Foreword 

On Montserrat there has long been a commitment 

to a balanced, integrated approach to forest conservation, 

designed at maintaining a range of functional 

habitats and assemblages of species. The major 

aims are (i) to promote sustainable use of natural resources 

and environmental goods and services in an 

equitable manner and (ii) to maintain biodiversity in 

its widest definition, including genes, populations, 

species and ecosystems. 

Over the years, a number of studies have been 

conducted on the biodiversity and natural environment 

of Montserrat, and recently, some conservation 

prescriptions have been tested, particularly on forest 

avifauna. While some of these efforts have produced 

useful data and are interesting conceptually, what 

have been largely lacking are mechanisms for translating 

sound conservation policies into routine practices 

in the field, based on the ecosystem approach. This 

inadequate application of conservation action is due 

primarily to limited capacity including human and 

financial resources, decision support systems and access 

to information. 

The apparent need for improved conservation 

action was brought into stark focus following the onset 

of volcanic eruptions in 1995 in which two‐thirds 

of the island was rendered inaccessible and a similar 

proportion of its forest was destroyed. As a result settlements 

and economic activities are expanding in 

areas where fragile ecosystems coexist and where 

competition for space is acute. Of particular concern 

was the plight of the Centre Hills Forest and surrounding 

habitats, the largest remaining tract of continuous 

forest on the island. 

The Centre Hills are of national, regional and 

global conservation importance because they support 

inter alia, assemblages of single‐island and regional 

endemic species of fauna and flora, as well as eight 

globally threatened vertebrate and plant species. The 

Centre Hills also provide many environmental goods 

and services which are important to sustainable livelihoods 

and quality of life. For example, all potable water 

comes from the Centre Hills; they serve as a buffer 

against the impacts of natural disasters such as hurricanes, 

floods and volcanic eruptions; and they control 

soil erosion thereby protecting agriculture and fisheries 

based livelihoods and beach, dive and eco‐tourism. 

From the start, it was recognised that conservation 

of the Centre Hills required a strategy for integrated 

management of the natural resources and the 

ecosystem services they provide on a sustainable basis, 

for the benefit of key stakeholders. As a result, a 

number of national and international partners, who 

have previously worked together on similar projects, 

presented a successful bid to the UK Darwin Initiative 

for a project to conserve the Centre Hills. Key partners 

in the project included the Ministry of Agriculture, 

Lands, Housing and The Environment; Montserrat National 

Trust; Montserrat Tourist Board; Royal Society for 

the Protection of Birds; Durrell Wildlife Conservation 

Trust and the Royal Botanic Gardens, Kew. The purpose 

of the project was to strengthen the capacity of the people 

of Montserrat to take targeted action to protect biodiversity 

and manage protected areas. 

In developing a management strategy for any 

resource, it is vital to know the resources that are available 

and in what quantity, where they are located, how 

they are changing over time and how these changes are 

impacting on the remaining resources. Therefore, before 

a management plan could be developed for the Centre 

Hills, a systematic assessment of biological resources 

was conducted. 

The biological assessment has provided robust 

data on which to base management of the Centre Hills 

and its biodiversity. It represents a first attempt at making 

a comprehensive assessment of the major plant, vertebrate 

and invertebrate animal taxa and the ecosystems 

of which they are a part. The key results and outputs of 

the biodiversity assessment and the highest priority conservation 

recommendations are summarised under the 

caption ‘The Report in Brief.’ Chapter 1 more fully summarises 

the findings and recommendations of the whole 

report, and Chapter 2 gives the background on Montserrat’s 

natural history and the Centre Hills Biodiversity 

Assessment Project. Entire chapters have been devoted 

to plants and habitats; invertebrates (with emphasis on 

beetles); amphibians and reptiles; birds; bats; and invasive 

rats. The appendices should not be overlooked as 

much valuable information is presented on invertebrates 

and native and non‐native plants. 

The report will be particularly useful to scientists, 

researchers, conservation managers, students and enthusiasts, 

as it represents the definitive text on Montserrat 

biodiversity following the onset of volcanic eruptions.

The biodiversity assessment of the Centre Hills, 

Montserrat, has been a significant effort, made possible 

only by an effective and close collaboration between 

the team of Montserratian and international 

biologists, forest rangers and taxonomic experts. The 

project team sincerely hopes that the Centre Hill’s 

unique and globally important biodiversity is better 

understood and will be made more secure thanks to 

this assessment. A number of people working for, or 

with, the Montserrat Department of Environment and 

Montserrat National Trust in the past or present made 

this project achievable, through their considerable 

skills, expertise and hard work, despite many challenging 

field conditions. These include, in no particular 

order, Lloyd Martin, James Daley, Calvin Fenton, 

Philemon Murrain, John Martin, James Boatswain, 

Lloyd Aymer, Jervain Greenaway, Gerard Gray and 

Claude Gerald. Their knowledge of the Centre Hills 

and passion for its wildlife is remarkable, and they are 

effective advocates for its conservation and sustainable 

use of its natural resources. 

The authors of the chapters in this volume deserve 

many thanks for all of their efforts; in the field, 

in the laboratory and at their desks. In terms of furthering 

our knowledge of the flora and fauna of the 

Centre Hills, Michael Ivie and his team at Montana 

State University, and Colin Clubbe, Martin Hamilton 

and colleagues at Royal Botanic Gardens, Kew, have 

made major contributions. Information about the invertebrates 

and plants of Montserrat has been massively 

improved through their efforts. The invertebrate 

and plant species checklists reported in an appendix 

to this volume are an invaluable resource for 

Montserrat. Geoff Hilton, Richard Allcorn and colleagues 

at the Royal Society for the Protection of Birds, 

in collaboration with the Department of Environment, 

have developed a systematic and well‐organised forest 

bird monitoring programme which delivers scientifically 

robust data on the state of the Centre Hills’ 

bird populations. These data are fundamental to the 

effective conservation of Montserrat’s birds and 

greatly strengthen this biodiversity assessment. Scott 

Pedersen from South Dakota State University and 

colleagues have invested much time, effort and money 

to research and monitor the bats of Montserrat over 

the past 10 years or more, providing vital information 

on this important taxon, which has been utilised in 

this report. Will Masefield of Durrell Wildlife Conservation 

Trust made a significant contribution to the bat 

survey in 2005, including catching the rare and little 

known white‐lined bat. Agnieszka Ogrodowczyk, 

also of Durrell, was meticulous and tenacious in leading 

an excellent survey of the reptiles and amphibians 

of the Centre Hills, which included hugely important 

finds of the Montserrat galliwasp that will advance the 

conservation of this unique but highly threatened and 

unknown species. 

Thanks to the ‘Centre Hills Project’, the findings 

of the biodiversity assessment are currently informing 

the design of a Management Plan for the Centre 

Hills that seeks to ensure this ecosystem is conserved 

over the long term. Carole McCauley, Stephen 

Mendes and Sarah Sanders of the RSPB have all 

worked extremely hard to ensure the Centre Hills will 

soon be designated as a National Park, with a suitable 

management infrastructure and an enabling legislative 

framework in place. The value of having a biodiversity 

assessment embedded into a management planning 

project is worth noting here and it is gratifying 

that these data are being actively used to inform conservation 

and not just sitting on a shelf. 

Throughout the biodiversity assessment, the 

people of Montserrat have shown overwhelming support 

for the project, despite having many other overriding 

issues to deal with, none more severe than the 

effects of the volcanic crisis on lives and livelihoods. 

Their friendliness and hospitality has been remarkable. 

The landowners in the Centre Hills area kindly 

allowed the project team to carry out the important 

biodiversity assessment fieldwork. The local media 

have shown a keen interest in the project and enabled 

the team to deliver information to people locally, and 

elsewhere, in order to raise awareness of the importance 

of Centre Hills biodiversity. Various people in 

the Governor’s Office and Department for International 

Development have also shown a keen interest 

and provided welcome support for the project. 

John Fa of the Durrell Wildlife Conservation 

Trust deserves much gratitude for conceiving and 

initiating the Centre Hills Biodiversity Assessment 

project. Also from Durrell, Sarah Seymour played a 

key role in supporting the management and delivery 

of the project, and Quentin Bloxam provided useful 

advice and encouragment. Finally, funding was provided 

by the Jersey‐based Elizabeth Violet Annie 

Rouse Settlement, the UK Darwin Initiative and all of 

the collaborating institutions.

The report in brief 

Background 

Through conversion of land to agriculture and 

human settlement, and impacts of natural disasters and 

invasive species, Montserrat has lost much of its natural 

habitats and the Centre Hills now supports the largest 

remaining tract of forest on this island. The Centre Hills 

forest can be regarded as internationally important due 

to an assemblage of island and regionally endemic species 

and highly significant, and in some cases entire, 

populations of eight globally threatened vertebrate and 

plant species. Although the majority of the Centre Hills 

forest is protected as a forest reserve, important habitats 

outside the boundary remain threatened with destruction 

and degradation, and the ecosystem as a whole is 

negatively impacted by invasive mammals and plants. 

The delineation of the forest reserve boundary was not 

based on robust data on the distribution of key biodiversity 

features. As momentum built in Montserrat for an 

effectively managed protected area for the Centre Hills, 

there was a clear need for a systematic biodiversity assessment 

to guide the design of a management plan for 

the Centre Hills forest. 

Project scope and objectives 

A team of national and international experts was 

assembled to conduct the Centre Hills Biodiversity Assessment 

(CHBA). Among its objectives were to: 

• inventory the biodiversity of the Centre Hills 

forest, by sampling a number of indicator taxa, 

including plants, invertebrates (with emphasis on 

beetles), amphibians, reptiles, birds and bats, 

• evaluate the status of species of biodiversity 

value and conservation concern, 

• map spatial patterns in biodiversity and important 

sites for key species in order to identify key 

biodiversity areas, 

• assess the status of invasive plants and mammals 

and their potential impact on indigenous flora 

and fauna, and 

• make recommendations for conservation management 

priorities within the Centre Hills forest. 

A variety of data‐gathering methods were employed 

in the assessment, including biodiversity surveys 

following a stratified (by elevation) random sampling 

design, ad‐hoc surveys, and analysis of existing 

datasets and specimen collections. 

Key results and outputs of the biodiversity 

assessment 

The Montserrat plant checklist contains 795 

known native species, 78 of which are of restricted‐range 

representing the highest priority plant species for conservation. 

Two of Montserrat’s endemic plants, Epidendrum 

montserratense and Rondeletia buxifolia, were discovered 

to have extremely limited distributions, the vast 

majority of which are not protected. The third endemic 

plant Xylosma serratum was not found and is feared extinct. 

The Centre Hills vegetation map clearly demonstrates 

the under‐representation of dry and littoral forest 

in the protected area. 

The number of invertebrate species known to 

occur in Montserrat is quadrupled to 1,241 species, including 

an increase in the number of known beetle species 

from 94 to an incredible 718 species from 63 families. 

The majority of these invertebrate species are 

probably only found in the Centre Hills forest. Roughly 

120 invertebrate species have been identified as being 

possibly unique to Montserrat, and these should be considered 

the highest invertebrate conservation priorities. 

The almost unknown endemic Montserrat galliwasp 

Diploglossus montisserrati was observed on three 

occasions, confirming the species’ continuing survival, 

and further suggesting that it has an extremely restricted 

distribution limited to the Woodlands Spring area. Interesting 

spatial patterns in mountain chicken Leptodactylus 

fallax population trends suggest hunting may be 

having a severe localised impact on their populations. 

An analysis of the bird monitoring data indicates 

highest population growth rates of the endemic Montserrat 

oriole Icterus oberi on the eastern flanks of Centre 

Hills, and important parts of its distribution falling outside 

of the northern boundary of the protected area. The 

Centre Hills appears to be a global stronghold for the 

endangered forest thrush Cichlherminia lherminieri. 

For the first time, all 10 species of bat known 

from Montserrat were captured in an annual survey. 

This included captures in the Centre Hills forest of single 

lactating females of the two most endangered species, 

yellow‐shouldered bat Sturnira thomasi vulcanensis 

and white‐lined bat Chiroderma improvisum, which had 

been feared extinct. A range of key resources for bats lie 

outside of the protected area boundary, and need protection 

to help safeguard Montserrat’s bat assemblage 

and to ensure that it continues to play vital ecological 

roles in the Centre Hills forest. 

The introduced and invasive brown rat Rattus 

norvegicus and black rat R. rattus were found to be common 

and widespread in the Centre Hills, with rats even 

reaching the highest elevations of Katy Hill. Both rat 

species are known to cause severe and pervasive damage 

to native flora and fauna in their introduced range, 

particularly on islands. Good evidence is revealed of a 

positive correlation between numbers of non‐native 

fruiting trees and the occurrence and numbers of rats in 

the Centre Hills forest. This has implications for how 

_______________________________________________________________________________________________________________________

invasive rats and other omnivores can be managed to 

reduce their impact on native flora and fauna. 

Based on a list of key biodiversity features and an 

assessment of threats, a set of conservation priorities for 

the management plan of the Centre Hills protected area 

is proposed. A number of proposed ‘strict conservation 

zones’ have been delineated to prioritise sites for protection 

and zone other management activities. 

Highest priority conservation 

recommendations 

1. Protection of dry and littoral forest lying to the 

east and north‐east of the Centre Hills is vital in 

ensuring the protected area is representative of 

all habitats in the contiguous Centre Hills forest. 

This habitat supports globally threatened plant 

species, important populations of a number of 

endemic reptiles, restricted‐range dry forest specialist 

birds and probably an important invertebrate 

assemblage. 

2. Protection of habitat in a hotspot for endemic 

plants that lies in the northern foothills of the 

Centre Hills outside the protected area boundary 

is an urgent priority. Tree protection orders are 

needed to safeguard veteran mango Mangifera 

indica trees in Belham Valley supporting important 

populations of Epidendrum montserratense. 

Ex‐situ conservation activities, including plant 

propagation and seed banking for both endemic 

plant species, are needed as a safety net should 

the worse happen in the wild. Full status assessments 

for both endemic plants should be conducted 

to further identify key sites. 

3. Enforce a series of appropriate regulations, and 

implement an improved population monitoring 

scheme, to ensure hunting of mountain chickens 

is sustainable. Improved biosecurity controls are 

needed at Montserrat’s borders and elsewhere to 

minimise the risk of the Chytridiomycosis fungus 

arriving in Montserrat and infecting mountain 

chickens. A co‐ordinated international captive 

breeding programme to hold a safety net population 

of mountain chickens in case of a Chytridiomycosis 

outbreak on Montserrat is also required. 

Protection of habitat in key ghauts lying outside 

of the Centre Hills protected area is a priority for 

this species. 

4. Strict protection of habitat in and around the site 

where galliwasps have been observed in Woodlands 

Spring is urgently required. A population 

assessment and ecological research to improve 

knowledge of the status and habitat requirements 

of the species must be conducted as soon as possible. 

Habitat restoration activities and lethal rat 

control is needed to reduce potential pressures on 

the galliwasp population. Captive breeding 

should be considered as a conservation intervention 

once results of population assessment are 

available. Awareness in the local community of 

the threat posed by domestic animals to the galliwasp 

needs to be raised. 

5. Monitoring of the Montserrat oriole and other 

forest birds should continue to provide early 

warning of population declines. Habitat protection 

in key Montserrat oriole sites lying outside 

the northern boundary of the Centre Hills protected 

area is important. 

6. Management of a variety of bat resources both 

inside and outside the Centre Hills forest is 

needed, including: maintenance or restoration of 

flow regimes of water courses; protection of riparian 

habitats; no removal of dead standing 

trees in the Centre Hills forest; and protection of 

bat colonies at Rendezvous Bluff and other key 

roosts. Research to understand habitat requirements 

and the status of the yellow‐shouldered 

bat and white‐lined bat is required as a priority. 

Strict protection of habitat in Bottomless Ghaut 

and tight regulation of public access to this ghaut 

should be considered. 

7. Habitat restoration activities are urgently required 

to reduce the impact of invasive mammals 

and plants on native flora and fauna in the Centre 

Hills forest, including: island‐wide pig eradication; 

feral cat control; and selective removal of 

non‐native fruit trees and rat control in experimental 

plots in key biodiversity areas. 

8. Strategic conservation planning should be conducted 

to engage relevant stakeholders and set 

out plans of conservation action for priority species 

and habitats. 

9. The sampling framework and data collection 

protocols used in this biodiversity assessment 

(and the forest bird and bat monitoring programmes) 

and the baseline data it has produced 

should be used to catalyse the implementation of 

a pressure‐state‐response monitoring scheme for 

the Centre Hills forest.

1. Biodiversity of the Centre Hills: importance, key features, 

conservation priorities and recommended actions 

R. P. Young, G. M. Hilton & L. Martin 

This chapter provides an in‐depth summary of 

the main findings of the Centre Hills Biodiversity Assessment 

(CHBA). The importance of the biodiversity of 

the Centre Hills ecosystem is evaluated in terms of species 

richness (the number of species at a particular site), 

endemicity (the number of species that are unique to a 

particular area, e.g. Montserrat, Lesser Antilles etc) and 

threat status. This evaluation allows us to identify key 

features (species, species assemblages, habitats and ecosystem 

processes) of Centre Hills’ biodiversity which 

represent priorities for conservation. The threats to 

these key features are then considered to allow recommendations 

on appropriate management actions. 

1.1. Importance of Centre Hills biodiversity 

at a national, regional, and global scale 

1.1.1. Species richness and endemicity 

The Caribbean region has been identified as one 

of 34 global biodiversity hotspots (Mittermeier et al., 

2005) due to its high levels of plant species richness 

(approximately 14,000 species) and endemism, which, 

due to extensive human‐related impacts, is highly 

threatened. The Caribbean is particularly rich in reptiles, 

the vast majority (93%) of the 502 described species 

being endemic to the region. It is also noted for exceedingly 

high levels of amphibian endemism (100% of 170 

described species are endemic to the region). Although 

much of this biodiversity is found in the western Caribbean, 

the Lesser Antilles is also recognised as supporting 

a considerable array of unique but threatened biodiversity 

of global importance. For example, it is remarkably 

rich in reptiles and has been identified as an Endemic 

Bird Area (Stattersfield et al. 1998), supporting 24 endemic 

bird species and seven endemic genera. 

Considering that the island of Montserrat is only 

just over 100 km2 in area, it is notable in a Lesser Antillean 

context for supporting a relatively large number of 

reptiles (eight native and one naturalised terrestrial species), 

bats (10 species), and as a result of the CHBA we 

now know that it has a very rich invertebrate assemblage. 

The CHBA invertebrate inventory has vastly increased 

the number of invertebrate species known to 

occur in Montserrat, from 306 to 1,241, including an incredible 

718 (up from 94 previously known) beetle species. 

On Montserrat, the majority of these invertebrate 

species are probably found only in the Centre Hills, 

which therefore supports the majority of the island’s 

biodiversity. The CHBA data were used to make a tentative 

prediction that over 4,000 animal species occur on 

Montserrat, with the large majority still undiscovered by 

science. 

The plant inventory revealed that nearly 800 native 

plant species are now recorded from Montserrat, 

and most of these are likely found in the Centre Hills 

forest. This forest comprises a dynamic mosaic of habitats 

which support a wide range of plants including 

many species of restricted distribution as well as several 

globally threatened species. This would qualify the Centre 

Hills as an Important Plant Area (IPA) as defined by 

the Important Plant Area programme co‐ordinated by 

Plantlife International and the World Conservation Union 

(Plantlife International 2004). The long‐term protection 

of the Centre Hills would be an important contribution 

to the implementation of Target 5 of the Global 

Strategy for Plant Conservation – ‘Protection of 50% of 

the most important areas for plant diversity assured’ 

(CBD, 2003). 

Montserrat is home to a range of single‐island 

endemic plants and vertebrates, i.e. species that are 

unique to Montserrat, nearly all of which occur in the 

Centre Hills and surrounding area (Table 1.1). Three 

species of plant are island‐endemics although one of 

these may now be extinct following the volcanic activity 

of the past decade. Six of the reptiles are unique to 

Montserrat at the species or subspecies level. This includes 

the almost unknown and rarely observed Montserrat 

galliwasp Diploglossus montisserrati, a lizard which 

can be considered a ‘biogeographical enigma’, in that it 

is the only member of its family (Anguidae) to occur in 

the Lesser Antilles. The Montserrat oriole Icterus oberi is 

the island’s only endemic bird and recent research has 

revealed that Montserrat has an endemic subspecies of 

bat, the yellow‐shouldered bat Sturnira thomasi vulcanensis 

(Genoways, 1998). Around 120 of the described invertebrate 

species, of which roughly 80 are beetles, are 

currently known only from Montserrat, and therefore 

may be single island endemics. The CHBA confirmed 

the continuing survival of four of the single‐island endemic 

vertebrates and plants (Epidendrum montserratense, 

Rondeletia buxifolia, Montserrat galliwasp and Sturnira 

thomasi vulcanensis), which were previously feared to be 

extinct. 

The Centre Hills support the vast majority of 

Montserrat’s terrestrial plants and animals, including 

most of its endemic species, and therefore in terms of the 

conservation of the island’s biodiversity it is clearly of 

utmost importance. 

1.1.2. Threatened species 

The Centre Hills forest supports significant (in 

some cases entire) populations of eight globally threatened 

(including two candidate globally threatened 

plants) vertebrate and plant species (Table 1.2). Consid‐

erable numbers of invertebrate species in the Centre 

Hills are also likely to be threatened, but insufficient 

information is available to make a formal Red List assessment. 

Three species, the Montserrat galliwasp (Day, 

1996), mountain chicken Leptodactylus fallax (Fa et al., 

2004) and Montserrat oriole (BirdLife International, 

2004) are classified as Critically Endangered (i.e. “at extremely 

high risk of extinction in the wild”), the highest 

level of threat as assessed by the World Conservation 

Union (IUCN). Although they have not yet been formally 

Red Listed, the CHBA has produced evidence that 

the two endemic plants, Epidendrum montserratense and 

Rondeletia buxifolia, will qualify as Critically Endangered. 

Two of the bat species are classified as Endangered, with 

a further three Near Threatened. Four plant species that 

occur in Montserrat are considered globally threatened 

despite being widely distributed in the Caribbean and 

Americas, as they are subject to over‐exploitation 

(mainly for timber) in many parts of their range. 

The Centre Hills qualifies as an ‘Important Bird 

Area’ (Sanders, 2006) because it supports a significant 

assemblage of ‘Restricted‐range [bird] species’ (see Table 

6.5 for a list), including important numbers of the 

two globally threatened species, forest thrush Cichlherminia 

lherminieri and Montserrat oriole. In this context, 

restricted‐range species are those that only occur in the 

Lesser Antilles and immediate surrounding area. 

The Centre Hills also supports a number of plant 

and vertebrate species that, whilst not threatened globally, 

are considered rare or declining in the Centre Hills 

and are worthy of conservation attention (Table 1.3).

Montserrat’s natural heritage. It is the only member of 

its family (Anguidae) in the Lesser Antilles, and is an 

enigmatic and Critically Endangered species. Four observations 

of possibly three individuals were made during 

the CHBA surveys in February and March 2006, con‐

firming the continued existence of this species, which 

was feared extinct (Ogrodowczyk et al. 2007). Extensive 

nocturnal amphibian and reptile surveys of the Centre 

Hills have been conducted as part of the CHBA and by 

the Department of Environment, but the galliwasp has 

only ever been observed in a highly localised area of 

Woodlands Spring (see Fig. 1.1). This suggests the species 

has an extremely restricted range, indeed one of the 

smallest distributions of any vertebrate animal species in 

the world. We cannot discount the possibility that it is 

more widely distributed in the Centre Hills but very 

difficult to find. Nevertheless, the status of the galliwasp 

is undoubtedly extremely precarious. 

The negative pressures on the Montserrat galliwasp 

are various and potentially disastrous, including 

predation by invasive alien mammals (e.g. rats, cats, 

dogs) and destruction of its forest habitat for urban and 

agricultural development. All known locations of the 

galliwasp fall just outside the forest reserve boundary 

(see Fig. 1.1) and therefore the species’ habitat may be 

completely unprotected. Another major problem is our 

lack of understanding of the ecological and conservation 

requirements of this key species.

1997/8 and 2005/6. 

The Montserrat oriole is arguably Montserrat’s 

best known endemic species, and acts as a flagship species 

for Centre Hills biodiversity and its conservation. 

Despite some evidence of a recovery from a population 

low in 2002/3 (Fig. 1.2), its population is still very small 

(in the range of 400‐700 pairs), with the vast majority of 

birds occurring in the Centre Hills, and it remains extremely 

threatened. Analysis of the Centre Hills Forest 

Bird Monitoring data shows that orioles have been increasing 

in number on the eastern flanks of the Centre 

Hills, whereas they appear to have declined on the western 

edge of the forest (see Fig. 1.3) [N.B. This figure and 

all other interpolated maps in this report are based on an Inverse

other figures in the report.

the Centre Hills and surrounding area 

not take into account other important factors such as elevation, 

topography, habitat type etc, and therefore should be 

interpreted with caution]. The 2004 monitoring data show 

that highest counts of Montserrat orioles occur on the 

eastern and southern flanks (Fig. 1.5). 

The bulk of the oriole population is protected 

from major habitat destruction within the Centre Hills 

forest reserve boundary, but a range of anthropogenic 

pressures still pose a severe threat to the Montserrat 

oriole. Perhaps most important is the predation of eggs 

and chicks by ship rats Rattus rattus, and a native bird, 

the pearly‐eyed thrasher Margarops fuscatus. Both of 

these predators occur at artificially high densities in the 

Centre Hills. Catastrophic natural events, while a natural 

feature of Caribbean islands, are also a major risk to 

Montserrat orioles. If more than one negative factor (e.g. 

unusual rainfall, hurricanes and eruptions) occurs close 

together in time, then populations with human‐induced 

limited ranges are clearly vulnerable to extinction, 

whether these events are ‘natural’ or not. Population 

modelling indicates that such events acting in combination 

greatly increase extinction risk for Montserrat oriole. 

1.2.1.c. Epidendrum montserratense 

Epidendrum montserratense is an epiphytic orchid, 

endemic to Montserrat. It is largely found on veteran 

mango trees Mangifera indica and sugar mill ruins, and 

all of these sites fall outside the current Centre Hills forest 

reserve boundary (Fig. 1.4). Like Rondeletia buxifolia 

(see below) this species must also be considered extremely 

vulnerable, as it has a highly restricted range, 

and enjoys no protection at either the habitat or species 

level. Interestingly, virtually all orchids found so far are 

located on anthropogenic features, i.e. non‐native mango 

trees and man‐made structures, which therefore play a 

vital role in the conservation of this species. The veteran 

mango trees found in the Belham Valley area provide 

the major location for Epidendrum montserratense, but are 

threatened by ongoing volcanic activity. 

1.2.1.d. Rondeletia buxifolia 

Rondeletia buxifolia is a small shrub, found only on 

Montserrat. To date, it has only been recorded growing 

outside the current Centre Hills forest reserve and therefore 

it enjoys no legal protection (Fig. 1.4). The majority 

of its population occurs in the northern foothills of the 

Centre Hills. During the CHBA, a significant population 

of this plant was lost due to the clearance of forest habitat 

for development. This species appears to have good 

dispersal ability, indicative of an early succession species, 

which in a natural forest would likely colonise gaps 

created by fallen trees. If the contemporary range of R. 

buxifolia is restricted to the modified habitats in the 

northern foothills of the Centre Hills, the habitat of this 

species may need to be actively managed rather than 

simply protected otherwise it will succeed to climax dry 

and mesic forest vegetation, unsuitable for R. buxifolia.

Falls in the South Soufrière Hills, where it was last recorded 

by Howard in the 1970s. Since this site was destroyed 

by a major pyroclastic flow during the 1995‐1997 

volcanic eruptions, this species may have disappeared 

from Montserrat and become extinct. However, since 

there are similar habitats to Great Alps Falls in the Centre 

Hills it is possible that this species still survives, but 

explorations so far have failed to find it. No ex situ material 

of this species exists so all that currently remains 

are dried herbarium specimens. A campaign to raise 

awareness of this species around Montserrat has been 

started in the hope that populations unknown to botanical 

experts may be discovered.

1.2.1.f. Yellow-shouldered bat 

The yellow‐shouldered bat Sturnira thomasi is 

only known from Montserrat and Guadeloupe. The 

form occurring on Montserrat is considered sufficiently 

different to the Guadeloupe population to be classified 

as a separate subspecies. The Montserrat subspecies, 

named Sturnira thomasi vulcanensis, has only been recorded 

with certainty on Montserrat on three occasions. 

It is thought to be mainly frugivorous (fruit‐eating), and 

therefore both native and non‐native fruiting trees are 

likely to be an important resource for this species. Previously 

suspected to be extinct following the volcanic activity, 

single individuals were captured in Bottomless 

Ghaut in 2005 and in 2006 (Fig. 1.5). Bottomless Ghaut 

therefore is currently the only known site in the world 

for this subspecies. As a species it is listed as globally 

Endangered (Chiroptera Specialist Group, 1996), but 

Fig. 1.6. Mean encounter rate of mountain chickens in the 

dry season between 1999 and 2005 (data from line 

transects repeated each year only). Error bars are 

standard errors 

very little is known about its distribution and population 

status on Montserrat (and Guadeloupe). Both captured 

individuals from Bottomless Ghaut were lactating 

females, providing evidence that the bat is breeding in 

Montserrat. 

1.2.1.g. Mountain chicken 

Along with the Montserrat oriole, the mountain 

chicken is a flagship species for the Centre Hills. It occurs 

only on Montserrat and Dominica and is prone to a 

wide‐range of threats, including disease, over‐hunting, 

habitat destruction and invasive mammals, and is classified 

as Critically Endangered. On Dominica it has suf‐

fered a catastrophic decline as a result of an outbreak of 

Chytridomycosis fungus. On Montserrat it is now restricted 

to the Centre Hills. All the above factors, combined 

with its use as a traditional food and its unusual 

breeding ecology, make the mountain chicken a key 

feature of Centre Hills biodiversity. 

Mountain chickens are currently most abundant 

in the east and south of the Centre Hills, particularly in 

the Fairy Walk area (see Fig. 1.5). Data generated by the 

Montserrat Department of Environment mountain 

chicken monitoring programme suggests that overall the 

mountain chicken population has remained fairly unchanged 

between 1999 and 2005, albeit with some fluctuations 

during the period (Fig. 1.6). The overall picture 

of no population change masks some spatial patterns in 

population trend. There is some evidence that populations 

in the eastern and north‐eastern ghauts are growing, 

whereas in the west and north‐west the mountain 

chicken is either absent or declining (Fig. 1.7). Mountain 

chickens are on average larger and in better body condition 

in the east compared to the west (J. Fa, unpubl. data). 

The Centre Hills Project socio‐economic assessment 

(McCauley & Mendes, 2006) revealed that mountain 

chicken hunting tends to happen in the west and north 

of the Centre Hills, which is the most plausible explanation 

for these spatial patterns. 

1.2.1.h. White-lined bat 

Like the yellow‐shouldered bat, the white‐lined 

bat Chiroderma improvisum was thought to be extirpated 

from Montserrat following the Soufrière Hills volcanic 

activity, but its survival was confirmed when a lactating 

female was captured in a patch of dry forest in Corbett 

Spring in 2005 during a CHBA survey (Fig. 1.5). This 

species has a very restricted global range, occurring only 

in Montserrat and Guadeloupe, and is classified as globally 

Endangered (Chiroptera Specialist Group, 1996). It 

has only been caught on Guadeloupe on three occasions 

and in Montserrat this species has previously been 

caught twice. Very little is known about this species, 

including its distribution and abundance in Montserrat. 

It is impossible to ascertain from a single capture how 

important Corbett Spring is for this species, but unfortunately 

the site has suffered damage from volcanic activity 

since the rediscovery. It is thought to be mainly 

frugivorous (fruit‐eating), and therefore both native and 

non‐native fruiting trees are likely to be an important 

resource for this species. 

1.2.1.i. Forest thrush 

The forest thrush appears to have become scarce 

in the other Lesser Antillean islands on which it occurs, 

and is classified as globally Vulnerable (BirdLife International, 

2004). The Centre Hills is thus probably a global 

stronghold for this species, and it should be considered a 

key species of conservation concern. Forest thrushes are 

largely concentrated in lower altitude forest around the 

edges of the Centre Hills, with hotspots in particular in 

the south‐west, north‐west and east (Fig 1.8), some of 

which fall outside of the forest reserve boundary and are

therefore unprotected. The map of change in forest 

thrush abundance (1997‐2004) shows a general increase 

in population density across much of the Centre Hills, 

but particularly in the east. 

1.2.1.j. Podocarpus coriaceus 

Montserrat’s only native gymnosperm plant, Podocarpus 

coriaceus, is listed in the IUCN Red List of 

threatened species as Least Concern (Conifer Specialist 

Group, 1998) using the IUCN 1994 Red List criteria. An 

important stand of large mature trees has been identified 

on the top of Hope Ridge (see Fig. 1.4), which contains 

some of the oldest trees in Montserrat and therefore this 

species is an important feature of Centre Hills biodiversity. 

To date, only limited data have been collected from 

the high ridges of the Centre Hills between 500‐700m. 

Therefore Fig. 1.4 under‐represents the true extent of 

occurrence for this species. The IUCN SSC Conifer Specialist 

Group is currently working to reassess all the 

gymnosperms using the IUCN 2001 Red List criteria. 

Data from the Montserrat biodiversity assessment have 

been made available to the chair of the Conifer Specialist 

Group to aid the reassessment. 

1.2.1.k. Brown trembler 

The brown trembler Cinclocerthia gutturalis is a 

restricted‐range species and is perhaps the only Montserrat 

bird species to have declined overall since forest 

bird monitoring began in 1997. It appears to be rare in 

Montserrat, almost entirely restricted to mesic forest, 

with a population size of around 400 birds, and therefore 

should be considered a species of local conservation 

concern. Brown tremblers appear to have their strongholds 

across a broad area of the eastern hills, plus some 

more localised hotspots in the western flanks, notably 

the Cassava Ghaut and Hope Ghaut areas (Fig. 1.9). 

1.2.1.l. Heliconia caribaea 

Heliconia caribaea is a relatively widespread 

clump‐forming plant of mid to higher elevation forests 

throughout the Caribbean and is Montserrat’s national 

flower. In Montserrat, the Centre Hills support the majority 

of the island’s population. It is an extremely important 

plant in the forest ecosystem and may be considered 

a keystone species. It produces abundant nectar at 

the base of the bracts. The large upright inflorescences 

can hold large quantities of water which support a widerange 

aquatic animal life and can provide important 

sources of water and food for many bird species. It is 

the major nesting site for Montserrat orioles who weave 

nests from the vascular material of old leaves and attach 

these to the lower side of established mature leaves. 

1.2.2. Species assemblages and habitats 

1.2.2.a. Invertebrates 

The CHBA has vastly increased our knowledge 

of the diversity of Montserrat’s invertebrate fauna, 

quadrupling the number of recognised species to 1,241 

(Table 1.4). The majority of these invertebrate species 

are probably found only in the Centre Hills. Due to the 

enormity of the task of cataloguing all the invertebrate 

species of the Centre Hills, the CHBA concentrated on 

investigating one taxonomic group that is known to be 

mega‐diverse, the beetles (Coleoptera). The known beetle 

fauna of Montserrat now stands at 718 species in 63 

families, with at least 81 possible single‐island endemics 

and 53 non‐native species. With an average body length 

of just 4.5mm, the vast majority of beetles (and other

invertebrates) that exist within the Centre Hills go completely 

unnoticed except by a few experts. 

In total, around 120 invertebrate species have 

been identified as possible single‐island endemics but in 

reality there may be hundreds. This means that the density 

of endemic animal species on Montserrat is drastically 

higher than understood hitherto. Another 54 beetle 

species may well be local endemics (i.e. only occur on 

Montserrat and a few neighbouring islands) and a further 

33 species are endemic to the Northeastern Antilles. 

Thus, 167 beetle species are known to occur either only 

on Montserrat or on this island and just a few 

neighbouring islands. Undoubtedly these numbers are 

underestimates, based on our still limited knowledge. 

These island and regionally endemic species should be 

considered the highest priority for invertebrate conservation. 

Because most invertebrate diversity on Lesser 

Antillean islands remains virtually unknown, it is extremely 

difficult to evaluate the importance of the Montserratian 

invertebrate fauna in a wider context. Drawing 

cautious comparisons of the Montserrat beetle fauna 

with the relatively well‐known faunas of Guadeloupe 

and Dominica suggests that Montserrat is indeed more 

diverse than would be expected for the size of the island 

and is important in a regional context. The invertebrate 

fauna of Montserrat is now one of the best documented 

of all island faunas in the Lesser Antilles. This knowledge 

should in itself be considered a key feature of the 

Centre Hills biodiversity. 

There are several unique aspects of Montserrat’s 

invertebrate fauna that elevate its importance from both 

a conservation and biogeographical perspective. A 

number of species are the only representatives of their 

taxonomic groups in the Lesser Antilles. For example, 

two very distinct beetle sister‐species of the genus 

Thonalmus are endemic to Montserrat, and represent the 

only known Lesser Antillean members of a small, West 

Indian endemic lineage. Another example is the evolutionary 

radiation of the anobiid beetle Trichodesma, with 

five undescribed species on Montserrat. No other Lesser 

Antillean island is known to harbour Trichodesma, with 

the closest site being in the Virgin Islands. The very odd 

undescribed weevil Prionarthrus n. sp. belongs to a 

group known otherwise from only a single described 

species from Brazil. The unique Eohomopterus from Katy 

Hill is one of only two extant species of the subfamily 

Paussinae known from the West Indies. Many more 

examples of species of high biodiversity value are documented 

in the invertebrate chapter in this report. 

1.2.2.b. Littoral and dry forest 

There has been little anthropogenic destruction of 

moist forest in Montserrat in recent years but, like elsewhere 

in the Lesser Antilles, dry and littoral forest has 

been greatly impacted by agricultural and urban development 

and is extremely vulnerable to further degradation. 

Only small patches of dry forest occur in the northeast 

and north‐west of the forest reserve, with the majority 

falling outside the boundary (Fig. 1.10). Most dry

and littoral forest in Montserrat is heavily impacted by 

grazing animals and and other non‐native mammals, 

but perhaps the least degraded and largest patch lies to 

the east and northeast of the Centre Hills, and is largely 

contiguous with the main forest block within the reserve 

boundary (Fig. 1.10). The dry and littoral forest is a key 

feature of the Centre Hills biodiversity for a number of 

reasons, and its protection is imperative: 

• Firstly, dry and littoral forest harbours high 

species richness of plants, invertebrates, reptiles 

and other biodiversity as mentioned in various 

sections above. 

• Secondly, dry forest is a key habitat for a number 

of locally and globally threatened species. For, 

example, the locally rare Antillean euphonia is 

thought to be a dry forest specialist. Three of 

Montserrat’s native globally threatened plants 

favour the dry forest: Cedrela odorata (stinking 

cedar) (Vulnerable: Americas Regional Workshop 

(Conservation & Sustainable Management of 

Trees, Costa Rica) 1998), West Indian mahogany 

Swietenia mahagoni (Endangered: Americas 

Regional Workshop (Conservation & Sustainable 

Management of Trees, Costa Rica) 1998), and 

lignum vitae Guaiacum officinale (Endangered: 

Conservation & Sustainable Management of 

Trees, Costa Rica) 1998). A fuller evaluation of 

the distribution of these species is needed, and an 

action plan developed, to ensure their 

conservation in Montserrat. 

• Thirdly, incorporating the dry and littoral forest 

that falls to the east and northeast of the Centre 

Hills into the protected area would allow it to 

encompass a full range of connected habitats, 

from the coast to the top of Katy Hill, and give as 

comprehensive coverage of Montserrat’s overall 

biodiversity as possible. 

• Finally, if contiguous with the main Centre Hills 

forest block, protection of this area of dry forest 

would provide an important buffer zone for the 

eastern flanks of the Centre Hills that are so 

important for a number of key species. 

1.2.2.c. Bats 

During 2005, for the first time since an extensive 

programme of bat research, including annual monitoring, 

started on Montserrat in 1978, all 10 species of bat 

were caught in a single survey. 

The bat fauna of Montserrat is a very important 

component of the Centre Hills ecosystem and is a conservation 

priority for three reasons: 

• Firstly, bats are the only extant native mammals 

in the Lesser Antilles 

• Secondly, they provide a number of ecological 

services that are key to the functioning of the 

Centre Hills ecosystem, particularly seed dispersal 

and pollination. Many fruit bats carry fruit 

and seeds further away from the parent plants 

than bird species and so are of particular importance 

in forest regeneration. Seed dispersal plays 

an important role in the regrowth of forests that 

have been damaged or destroyed (by volcanoes, 

hurricanes, clearance for agriculture, etc) and for 

some trees, bats are the main agents by which 

new areas can be reforested. Many economically 

important trees have closely evolved with bats as 

their main or only pollinators e.g. calabash Crescentia 

cujete, mango, banana Musa acuminata, and 

cashew Anacardium occidentale. 

• Bats are sometimes considered ʺkeystone speciesʺ 

(after the keystone that symbolically holds 

up an entire building) because the loss of these 

species from an ecosystem may cause pervasive 

negative effects. 

• Finally, of the 10 species that occur in Montserrat, 

two are globally threatened and three are considered 

‘Near Threatened’. Over the past 10 years, 

all of Montserrat’s bat species have been caught 

within or in the immediate vicinity of the Centre 

Hills forest. 

Due to their capacity for ranging over wide areas, 

it is difficult to identify key sites and habitats for bats 

within the Centre Hills. However, from the biodiversity 

assessment and long‐term monitoring data (S. Pedersen 

and team) a number of sites within the Centre Hills 

seem to be particularly important: the northeast region 

around Bottomless Ghaut; the Sappit River and Daly 

watershed system; Hope, Runaway, Cassava and Soldier 

Ghauts as well as Lawyers are other important sites for 

bats in the Centre Hills. The Centre Hills forest as a 

whole should be considered a vital habitat for bats on 

Montserrat, particularly frugivorous species, for foraging, 

roosts and nursery sites. Water bodies outside the 

Centre Hills boundary are also important sites for bats, 

for example, the Belham River is a key site for the bulldog 

bat Noctilio leporinus and funnel‐eared bat Natalus 

stramineus. 

However, given that some species of bat (e.g. 

Brachyphylla cavernarum) will regularly travel long distances 

between various resources, it is vital that conservation 

planning for the Centre Hills takes into account 

important bat resources that fall outside of the forest 

reserve boundary. For example, caves are important 

roost sites, at which large numbers of bats may congregate. 

Most importantly, a cave at Rendezvous Bluff next 

to Little Bay houses a large colony of 5,000‐6,000 individuals 

of Lesser Antillean fruit bats Brachyphylla cavernarum, 

and is probably vital for this species on Montserrat, 

their other main roost at Mosquito Ghaut having 

been lost to the volcano. The tarrish pits south of Belham 

Valley house the only known roosts for funneleared 

bats on Montserrat and therefore warrant protection.

1.2.2.d. Endemic reptiles 

With six reptiles endemic to Montserrat at either 

species or subspecies level, this group has the highest 

endemism of all vertebrate animal and plant taxa on the 

island. In total, 11 reptile species (although three may 

have been introduced by humans), occur on Montserrat, 

which therefore has high species richness for a Lesser 

Antillean island of its size (Ricklefs & Lovette, 1999). 

Compared to other vertebrate taxa, such as birds or bats, 

reptiles on islands tend to be habitat specialists, and 

therefore a range of habitat types needs to be protected 

for this assemblage. 

The CHBA surveys revealed a potentially important 

area of high herptile (reptiles and amphibians) species 

richness on the central western flanks of the Centre 

Hills, as well as a possible second area on the eastern 

side (Fig. 1.11). There was some evidence that mesic 

forest was the richest habitat type for reptiles, because it 

is a zone where species that are characteristic of both 

wetter and drier forests overlap. Of the endemic reptiles, 

the reasonably abundant Leeward racer is important, 

because elsewhere in the Lesser Antilles other species 

(and subspecies of the same species) from this family 

have suffered catastrophic declines due mainly to predation 

by the invasive small Indian mongoose Herpestes 

auropunctatus (which was never introduced into Montserrat). 

1.2.2.e. Elfin woodland 

The distinctive elfin woodland occurs at the highest 

elevations of the Centre Hills, on the top Katy Hill 

and in the high altitude area at the top of Hope Ridge 

(Fig. 1.10), and is thought to be a restricted habitat type 

within the Lesser Antilles. It is possibly the most vulnerable 

component of Montserrat’s biodiversity to the 

effects of global climate change. 

1.2.3. Ecosystem 

1.2.3.a. Shape and structure 

The Centre Hills is currently favoured by being a 

relatively continuous forest block, with a roughly circular 

shape (see Fig. 1.10), so minimising the edge‐effects 

that can be so damaging to small tropical forest blocks 

(Laurance et al., 2002). The structure of the Centre Hills 

forest is relatively intact, i.e. with few large cleared areas, 

and therefore it will be more resistant to hurricane 

damage than if it were highly fragmented. 

1.2.3.b. High densities of rats 

One negative but important feature of the Centre 

Hills fauna is the presence and abundance of the invasive 

brown rat Rattus norvegicus and black rat R. rattus. 

All available evidence from the CHBA and other recent 

field research points to rats occurring throughout the 

Centre Hills, even at the high elevations, and at particularly 

high density. The CHBA has provided compelling 

Fig. 1.12. Map showing the proposed highest priority strict conservation zones within and outside the Centre Hills protected 

area. Note that in order to accurately delineate a number of the zones, further surveys of key habitats and species 

are needed 

_______________________________________________________________________________________________________________________ 

22 


evidence that rat density is associated with numbers of 

non‐native fruiting trees in the local vicinity, presumably 

because they provide an abundance of food for rats. 

The negative impacts of rats on island biodiversity are 

well‐documented, and pose a major and pervasive 

threat to the Centre Hills ecosystem. Rats currently have 

a large negative impact on some of the most important 

and vulnerable species in the Centre Hills, including the 

Montserrat oriole, and probably the galliwasp and 

mountain chicken. 

1.3. Threats to key biodiversity features and 

recommended management 

recommendations 

The main threats to each of the key biodiversity 

features described above are given in Table 1.5, along 

with recommended management actions to remove or 

mitigate these threats. A number of the most wideranging 

pressures on Centre Hills biodiversity are discussed 

in detail outside the table, with brief information 

on recommended management actions. 

Similar to other islands in the Caribbean region 

and elsewhere around the world, invasive alien species 

pose perhaps the most severe threat to Montserrat’s native 

biodiversity. Black rats, brown rats, feral pigs, and a 

number of invasive plant species are the most problematic. 

Pigs are capable of causing severe damage to island 

flora and fauna, and an island‐wide eradication programme 

is a priority conservation action. Eliminating 

the negative impacts of rats through lethal control over 

the whole of the Centre Hills forest would be prohibitively 

expensive with current technology. However, the 

CHBA provided compelling evidence that rat numbers 

are highest where non‐native fruiting trees are abundant, 

presumably because they provide an abundance of 

food for rats. Zoned removal of these non‐native fruiting 

trees would be feasible (with sufficient money and 

expertise), and should lead to a reduction in numbers of 

rats and therefore the negative impacts they exert on 

native biodiversity. It should be noted that non‐native 

tree management would need to be conducted simultaneously 

with localised lethal rat control, to ensure that 

rats do not temporarily increase their intake of native 

flora and fauna when exotic food availability is reduced. 

Native pearly‐eyed thrashers Margarops fuscata also occur 

at artificially high density in the Centre Hills, probably 

because they are able to exploit abundant fruit for 

food. They have a negative impact on other species such 

as the Montserrat oriole, as well as being an agricultural 

pest in Montserrat. 

Removal of non‐native fruit trees from the Centre 

Hills would, however, need to take into account the 

needs of people who harvest fruit, and native species, 

such as bats, that feed on these trees. Zoning fruit tree 

removal in remote areas where fruit is not currently harvested 

and offsetting the loss in fruit productivity by the 

creation of community orchards and banana plantations 

outside the Centre Hills are potential management actions 

that would partially address this. It is important to 

note however that habitat restoration, including nonnative 

tree weeding, is likely an essential tool in improving 

the status of a number of key species, which occur 

outside of, or just within, the Centre Hills forest reserve. 

The most pressing example of this is the Montserrat galliwasp. 

Although habitat loss and degradation has not 

been widespread within the Centre Hills forest reserve 

boundary in recent years, destruction of vegetation does 

represent an existing threat to a number of biodiversity 

features, particularly, the galliwasp, endemic plants, and 

dry and littoral forest. These species and habitats are a 

vital component of Montserrat’s natural heritage and 

must be protected and/or managed sustainably. We 

recommend establishing a network of strict conservation 

zones (see Fig. 1.12 for the location of suggested strict 

conservation zones) which encompass the most important 

sites for these species and habitats (N.B. futher surveys 

are required to accurately delineate a number of the 

zones), within which appropriate management activities 

can be implemented, including, habitat restoration, habitat 

protection invasive species control, intensive monitoring, 

etc. The network of strict conservation zones also 

includes areas of forest within the Centre Hills forest 

reserve boundary, in which various management actions 

are recommended to safeguard key biodiversity features. 

See Table 1.5 for a list of recommended activities 

for the strict conservation zones. 

Finally, another problem hindering conservation 

of Centre Hills’ biodiversity, particularly those species 

not well protected by the forest reserve, is a lack of strategic 

conservation planning. Funding from the Overseas 

Territory Environment Programme has recently been 

secured to conduct a project entitled ‘Strengthening capacity 

for Species Action Planning in Montserrat’. This 

project was launched in September 2007 and will focus 

on developing the skills and resources in the Montserrat 

Department of Environment to conduct species action 

planning. By August 2009, Species Action Plans will be 

produced for five of Montserrat’s most threatened species: 

Montserrat galliwasp, mountain chicken, yellowshouldered 

bat, Epidendrum montserratense and Rondeletia 

buxifolia

2. Background to the Centre Hills biodiversity assessment 

R. P. Young & G. M. Hilton 

In this chapter, brief background information on 

the natural history of Montserrat is given, followed by 

the need for, and scope of, the Centre Hills Biodiversity 

Assessment (CHBA) project. This includes discussion of 

threats to the biodiversity and ecosystem goods and 

services of the Centre Hills, the aims and design of the 

project, and the structure of the project team. Finally, 

details are provided on how results of this project will 

be used to inform a management plan for the 

conservation of the Centre Hills, which will help support 

Montserrat to meet its national and international 

obligations for biodiversity conservation. 

2.1. A brief natural history of Montserrat 

Montserrat is located in the northern part of the 

Lesser Antilles island arc in the West Indies (62° 12ʹ 

west, 16° 45ʹ north) (Fig. 2.1), between the islands of 

Nevis and Guadeloupe, approximately 60 km northwest 

of the latter island. It lies on the eastern edge of the 

Caribbean tectonic plate in the subduction zone with the 

Atlantic plate and is volcanic in origin, emerging from 

the Caribbean Sea relatively recently ‐ around 25 million 

years ago. The island is mainly composed of andesitic 

lavas and volcaniclastic rocks produced by domeforming 

eruptions. It is 102 km 2 in area and consists of 

four main volcanic centres. From oldest to youngest 

these are the Silver Hills in the north, the Centre Hills in 

the centre (the focus of the CHBA), and the active 

volcano of the Soufrière Hills as well as South Soufrière 

Hills in the south (see Fig. 2.2 and 2.3). Average annual 

daytime temperature is 28 o C with annual rainfall 

varying between 1,100mm at the coast to 2,100mm at 

higher elevations. Montserrat has a humid tropical 

climate with a wet season from around July to 

December, with a drier season in the intervening period, 

although large seasonal and annual variation in rainfall 

does occur. 

Montserrat falls in the Lesser Antilles 

biogeographical province. Its terrestrial flora and fauna 

is influenced strongly by South America and to a lesser 

extent by Central and North America. Like other Lesser 

Antillean islands, Montserrat is an oceanic island and 

has never been connected to the mainland. Therefore all 

its fauna and flora have colonised by crossing the sea, 

both northwards from South America up the Lesser 

Antillean island chain and also southwards from the 

Greater Antilles. This has a number of implications for 

Montserrat’s assemblage of animals and plants. For 

example it explains the dominance of species with good 

dispersal ability in the vertebrate species assemblage, 

such as bats, birds and reptiles, and the absence of 

terrestrial mammals, freshwater fish and the scarcity of 

amphibian species. Flying vertebrates (i.e. bats and

birds) in the Lesser Antilles tend to show ties with 

Central and North as well as South America. The nonflying 

vertebrates in the Lesser Antilles, such as 

amphibians and reptiles which passively disperse, 

display a very strong South American influence. It is 

thought the prevailing south‐east to north‐west current 

in the Caribbean Sea carried much of the passivelydispersing 

fauna on flotsam from the mouths of major 

rivers in South America. 

The wider Caribbean has high levels of diversity 

and endemicity, particularly in plants, amphibians and 

reptiles, and the region has been identified as a 

‘biodiversity hotspot’ (Myers et al., 2000). However 

much of this diversity is found in the Greater Antilles. 

The Lesser Antillean islands tend to be relatively 

species‐poor in relation to a similar size region in the 

Greater Antilles or on mainland America at similar 

latitudes. The number of species that occur on Lesser 

Antillean islands is related to a number of factors (some 

of which are correlated), including island size, 

topography, diversity of habitat, and distance from the 

mainland or other islands. Due to its small size and 

remoteness from mainland South America, Montserrat is 

not the most biodiverse Lesser Antillean island. 

However, given its small size, it does support a large 

number of island and regionally endemic species, and is 

rich in reptile and bat species. The Caribbean as a whole 

has very high reptile diversity and endemicity, with 

large evolutionary radiations of groups such as the anole 

lizards (Anolis), dwarf geckos (Sphaerodactylus), and 

racer snakes (Alsophis), which is reflected in 

Montserrat’s relatively large reptile assemblage, with six 

island endemics at species or subspecies level.. The level 

of island endemism in the plants on Montserrat is low, 

with three recognised endemic plant species. Lower 

levels of island endemicity also occur in the volant 

groups of bats and birds, with one endemic bird species 

(Montserrat oriole Icterus oberi) and one endemic 

subspecies of bat (yellow‐shouldered bat Sturnira 

thomasi vulcanensis). Far less is known about the 

biogeography of invertebrates and reliable data with 

which to evaluate endemicity levels in this group do not 

exist, but it is the subject of investigation as part of this 

project (see Chapter 4).

A range of habitat types occur on Montserrat, 

with vegetation communities largely determined by the 

amount of rain, and to a lesser extent exposure, which is 

in turn closely linked to elevation. In lowland areas, 

where the least rain falls, dry scrub and forest tends to 

dominate. In certain coastal areas which are affected by 

sea spray, a thin band of littoral forest is found. Wetter 

riparian forests are found along the many ravines, or 

ghauts, that run down from the mountains to the coast. 

As elevation increases, so does rainfall, and the forest 

changes from dry to mesic and eventually wet forest at 

the higher altitudes. Elfin woodland occurs at the 

exposed peaks of the highest mountains. The Centre 

Hills are predominantly covered by mesic and wet 

forest, with small areas of elfin woodland at the peaks 

and dry forest at lower elevations. See Fig. 2.4 below for 

a map of the predicted pre‐human vegetation cover on 

Montserrat (also excluding any impacts from volcanic 

activity). 

The majority of Montserrat’s natural vegetation 

has been heavily modified following the arrival of 

Europeans in the 17 th century. Only small fragments of 

pristine habitat at the highest elevations and on the 

steepest slopes of the Soufrière and Centre Hills remain 

after centuries of intensive exploitation. Forest was 

cleared mostly for the cultivation of sugar cane, and 

other cash crops such as cotton, banana and tobacco. 

The large scale forest clearance has resulted in a number 

of environmental problems, such as changes to water 

catchments, flooding, and significant loss of topsoil 

through erosion in areas such as the Silver Hills. 

Agricultural production declined during the 20 th 

century, which allowed forest in the Soufrière and 

Centre Hills to regenerate naturally, and this has been 

supplemented by private and public reforestation efforts 

in these areas. However, many alien trees and other 

plant species remain in the secondary forest, so in terms 

of plant species composition, it is considerably modified 

from the original native forest. Natural lowland habitats 

in Montserrat remain very restricted in extent and are 

generally limited to narrow areas along steep sides of 

ghauts and small areas of littoral and dry scrub. 

Montserrat’s indigenous flora and fauna has also 

been modified through the introduction of non‐native 

mammals. Amerindians are believed to have introduced 

vertebrate species for food such as agouti Dasyprocta 

antillensis, red‐footed tortoises Geochelone carbonia, and 

probably green iguanas Iguana iguana, but the 

unintentional introduction of black Rattus rattus and 

brown rats R. norvegicus by European settlers is highly 

likely to have had much more wide‐ranging impacts on 

Montserrat’s biota. Other invasive alien species include 

marine toads Bufo marinus, house mice Mus musculus, 

feral cats Felis catus and pigs Sus scrofa and various plant 

taxa. 

On 18 th July 1995, following a three‐year period of 

increased seismic activity, the Soufrière Hills volcano 

began erupting. The eruption has been characterised by 

the repeated growth and collapse of a lava dome with 

associated pyroclastic flows, vulcanian explosion and 

debris flows, similar to the activity that produced the 

ancient deposits making up the rest of the island. Since 

1995, pyroclastic and mud flows and rock and ash falls 

have destroyed the capital Plymouth and other southern 

settlements, with the loss of 19 lives. The southern 60% 

of the island has been completely evacuated and an 

exclusion zone established. A large number of 

Montserratians relocated abroad, resulting in the 

population falling from 11,000 to around 4,000 people, 

with approximately 5,000 people currently living on the 

island. At the time of writing the volcano remains 

highly active and continues to affect the lives of 

Montserratians. 

The volcano has had a major impact on the forest 

and other habitats in the south of Montserrat, with most 

vegetation completely destroyed, including the pristine 

habitats at the peaks of the Soufrière Hills. Only a small 

forested area on the south‐eastern flanks of the South 

Soufrière Hills remains, which due its topography 

escaped pyroclastic flow. The rapid destruction of 

_______________________________________________________________________________________________________________________ 

33 


vegetation resulted in large scale habitat loss for a 

number of Montserrat’s endemic and endangered 

species and has presumably resulted in large population 

declines for many. As a result of habitat destruction in 

the south, approximately 60% of forest cover in 

Montserrat was lost. 

2.2. Need for project 

The Centre Hills now supports the largest 

remaining tract of forest in Montserrat and consequently 

supports the majority of its biodiversity, including a 

large number of island endemic species. It is also a key 

site for numerous globally threatened species. For 

example, the Centre Hills area is the only known site on 

earth for the extremely rare and almost unknown 

Montserrat galliwasp Diploglossus montisserrati, a subspecies 

of the yellow‐shouldered bat, as well as an 

endemic orchid Epidendrum montserratense and species of 

shrub Rondeletia buxifolia which both occur in the 

foothills. The Centre Hills supports the world’s largest 

population of the endemic Critically Endangered 

Montserrat oriole and very possibly of the Critically 

Endangered mountain chicken frog Leptodactylus fallax 

and Vulnerable forest thrush Cichlerminia lherminieri. 

The contiguous forest of the Centre Hills encompasses 

the largest and least disturbed areas of all the major 

terrestrial vegetation types that occur in Montserrat. 

The Centre Hills is also now by far the most 

important site in terms of the provision of ecosystem 

services for Montserrat. It is the most important water 

catchment and supplies the vast majority of Montserrat’s 

human water supply. The forest cover is essential to the 

regulation of the water supply and prevention of 

flooding at lower elevations. The forest also prevents 

soil erosion, which would lead to the siltation of streams 

and localised marine habitats. Being the largest forested 

area it is also extremely important for carbon 

sequestration and local climate regulation. It is 

noteworthy that the services provided by the Centre 

Hills and their economic value have never been studied 

and quantified. Nevertheless, the Centre Hills forest is 

undoubtly of great importance both for Montserrat and 

for its international environmental obligations. It needs 

to be protected and sustainably managed to conserve its 

biodiversity and ecosystem services. 

The Centre Hills also provides Montserrat with a 

range of aesthetic, cultural and recreational values. For 

example, it supports the main populations of the 

national bird, the Montserrat oriole, and the national 

plant, Heliconia caribaea, and has a network of trails 

which are used by Montserratians and visitors. It also 

has financial value, generating income from tourism, 

and also on a smaller scale from the extraction of nontimber 

forest products, for example, mountain chicken 

hunting. 

2.2.1. Threats to Centre Hills biodiversity 

Habitat destruction 

Currently, habitat destruction in the Lesser 

Antilles is primarily driven by pressure for tourist and 

urban development, and for agricultural land. In the 

Centre Hills of Montserrat, however, forest destruction 

has been minimal in recent years. Since 2000, the core 

area of the Centre Hills forest at mid to upper elevations 

has received statutory protection under the Protected 

Forest Order and Forest Reserve Order of the Forestry, 

Wildlife, National Parks and Protected Areas Act. The 

boundary of the forest reserve was demarcated in 2002 

encompassing an area of 11.3 km 2 . Land within the 

reserve is owned by private individuals and estates 

(60%) and by the Crown (40%). Through the Orders, 

restrictions are placed on activities within the forest 

boundary, including on clearing of land, cutting trees, 

grazing livestock and littering, and there are provisions 

for the establishment of management agreements with 

landowners. However no management plan has ever 

been implemented for the Centre Hills and the 

Department of Environment, which has a mandate over 

protected areas, has no regulations or enforcement codes 

under which to effectively manage activities within the 

forest boundary. Furthermore, much of the contiguous 

area of the Centre Hills forest at lower elevations lies 

outside of this forest reserve boundary, particularly on 

the eastern flank of the hills. Due to lower rainfall at 

these elevations, this tends to be dry forest which is 

vulnerable to further clearance and over‐grazing. 

Across the Lesser Antilles, dry forests occur in the 

lowlands nearer to the coast, and are therefore more 

susceptible to development pressure than higher 

altitude and relief rainforest areas. This is true of 

Montserrat, where mesic and wet forest are subject to 

relatively little pressure for clearance, because they are 

typically on steep slopes that are difficult to access and 

vital for watershed protection, but dry forest has been 

largely destroyed. 

Minor incursions for building development 

during the post‐volcano reconstruction have caused 

relatively small‐scale forest loss on the west and northwest 

flanks of the hills outside of the reserve boundary, 

as have agricultural clearances. Conversely, there has 

been considerable forest regeneration (reverting from 

agricultural land) in the east of the Centre Hills during 

the last ca.20 years (J. Daley & P. Murrain pers. comm.). It 

is important to point out that there has hitherto been no 

monitoring of landcover in the Centre Hills area, so 

there is no quantitative information on changes in forest 

cover. 

Forest patch configuration 

The Centre Hills is currently favoured by being a 

relatively continuous forest block, with a roughly 

circular shape (see Chapter 3 for vegetation map). This 

minimises the edge‐effects that can be damaging to 

_______________________________________________________________________________________________________________________ 


34

small tropical forest blocks (Laurance et al., 2002; Watson 

et al., 2004). 

We do not know anything about patterns of 

movement of animals and plants between the larger, 

now destroyed, southern forest block and the surviving 

Centre Hills forest. One can speculate that some species 

in the Centre Hills existed as sink populations that were 

maintained by immigration from the larger, higher and 

possibly more natural southern forests. Any such sinks 

would now be ‘exposed’ by the loss of the southern 

forests. Current forest bird monitoring data indicates 

that this is not likely to have been the case to a major 

extent for any of the forest bird species, since none have 

shown consistent declines since the loss of the southern 

forests. Nevertheless, both brown trembler and 

Montserrat oriole have shown apparent declines during 

parts of the 1997‐2006 period, and it is possible that 

immigration from the south would have boosted their 

populations in earlier periods. 

In any event, the existence of two largely 

separate, substantial sized forest blocks in Montserrat – 

the Centre Hills and the Soufrière/South Soufrière Hills ‐ 

likely reduced the extinction risk for many species, by 

reducing the probability that a single catastrophic or 

stochastic event could eliminate the whole‐island 

population. This is particularly so if the negative factors 

that affected the two forest blocks – for example rat 

population explosions, hurricanes, droughts and 

volcanic eruptions – did not occur simultaneously at 

both sites. 

Isolation and edge‐effects are likely to be most 

severe for the degraded dry forest areas that are 

contiguous with the main Centre Hills forest block, 

predominantly in the north‐east of the island. 

Invasive alien animals 

Both black (ship) rats and brown (Norway) rats 

occur in the Centre Hills, having been introduced since 

European settlement. Rat numbers appear to vary 

greatly between years, but are generally high, often 

exceptionally high, even up to the summits of the hills 

(Montserrat Centre Hills Project, unpubl. data). In other 

island ecosystems, rats are known to reduce tree 

regeneration, greatly reduce macro‐invertebrate and 

small herptile abundance and to predate birds’ eggs and 

chicks (Allen et al., 1994; Wilson et al., 2003; Towns et al., 

2006). Recent research work in the Centre Hills has 

confirmed that rats (apparently mostly black rats) are 

major predators of Montserrat oriole nests, and also 

predate forest thrush nests (G.A.L. Gray pers. comm.). 

Population models show that rat predation is sufficient 

to drive a decline in the Montserrat oriole population in 

the Centre Hills in some years. 

The status of feral cats in the Centre Hills is 

unclear. Signs of cats have been found in remote areas of 

the Centre Hills, as has evidence of cat predation on 

forest thrush and bridled quail‐doves Geotrygon mystacea 

(G.M. Hilton pers. obs.). It has not been definitively 

demonstrated that there is a true feral population, rather 

than just wandering domestic animals, though the 

former seems probable. There is no information on the 

cat population density or impacts of cats on Centre Hills’ 

biodiversity, but it is a cause for concern. The dense rat 

(and house mouse) population seems likely to be 

capable of sustaining a relatively large cat population, 

which could in turn have a significant predatory impact 

on native birds, reptiles and amphibians. Fortunately, 

the small Indian mongoose Herpestes auropunctatus, 

which is a major conservation problem on some West 

Indian islands (Stattersfield et al., 1998; Kairo et al., 2003), 

is not present on Montserrat. 

Feral pigs are thought to be a relatively new 

problem on Montserrat, having appeared in the Centre 

Hills since 2000, following the escape of domestic stock 

from abandoned agricultural areas in the south of the 

island. They spread through much of the Centre Hills 

with astonishing speed until a major control effort in 

2003‐4 pushed them back to the south‐eastern edges of 

the hills. Since the relaxation of control, populations are 

recovering, and pig‐sign was once again recorded near 

the summit of Katy Hill – relatively northward in the 

hills ‐ during 2005. Hitherto, the impact of pigs has been 

relatively slight, because they have not had time to reach 

high densities. In some island forests, such as in Hawaii, 

pigs have had catastrophic impacts, effectively 

destroying forests by preventing regeneration. In other 

islands, they have less massive, but still important 

impacts as predators and herbivores (Kessler, 2001; 

Schuyler et al., 2001; Sweitzer & Van Vuren, 2004). Their 

ultimate impact on the Centre Hills if the population is 

not checked is unclear. They are likely to be effective 

predators of ground‐nesting birds and we speculate that 

they could have a disastrous predatory impact on larger 

terrestrial herptiles, such as mountain chicken and 

Montserrat galliwasp (Kessler, 2001; GISD, 2006a). Their 

rooting activities may significantly deplete riparian 

Heliconia stands (G.M. Hilton pers. obs.), which could 

cause loss of Montserrat oriole nests and nesting 

territories. Whether they become significant ecosystem 

engineers, changing habitat structure and even, 

ultimately, destroying the forest remains to be seen. 

Agoutis and house mice are widespread and 

abundant in the Centre Hills, the former probably 

introduced by Carib Indians (Blankenship, 1990) and the 

latter presumably by Europeans. Their impacts are 

unknown. They may have some indirect effects, for 

example by affecting plant community composition 

through herbivory, and, in the case of mice, reducing 

invertebrate populations through predation (GISD, 

2006d). 

Large domestic grazing mammals regularly make 

incursions into the Centre Hills, especially goats Capra 

hircus and cattle Bos taurus. The former are a concern. 

As with cats, it is not clear whether there is a true feral 

population, or simply poorly controlled domestic stock, 

and it is not clear whether they are currently increasing. 

Both species can have major effects on forest vegetation 

structure (GISD, 2006c, b).

Alien fruit trees and opportunistic generalists 

In parts of the Centre Hills, alien fruit trees such 

as bananas Musa acuminata and mangos Mangifera indica 

are relatively abundant, a consequence of a long history 

of agriculture within and around the site. Most native 

fruit species produce relatively small fruits, whereas 

some of the alien species produce large fruits that are 

highly profitable to vertebrate frugivores. It is notable 

that in the Centre Hills opportunistic generalists (e.g. 

rats and pearly‐eyed thrashers Margarops fuscata) are 

extremely abundant. The density of pearly‐eyed 

thrashers in the Centre Hills is among the highest in 

their range (Arendt, 2006). This may simply reflect the 

fact that Montserrat is a relatively species‐poor island 

ecosystem that is subject to periodic catastrophic 

disturbance; this situation tends to lead to communities 

that are species‐poor, supporting high densities of a few 

adaptable species (MacArthur et al., 1972). Another (not 

mutually exclusive) hypothesis is that the abundance of 

alien fruit trees (and perhaps other anthropogenic food 

sources such as small agricultural plots) permits these 

opportunists to reach very high densities. Both as 

competitors and predators, rats and thrashers can have 

important detrimental effects on a wide range of native 

flora and fauna. They are notable predators of other 

small vertebrates, including birds’ nests, and major 

consumers of large invertebrates (Arendt, 2006; Towns et 

al., 2006). Thus it is possible that anthropogenic changes 

to the plant community composition in the Centre Hills, 

have led to an ecosystem which favours opportunisticgeneralists 

to an excessive degree, with negative 

consequences for other fauna. Direct evidence for such a 

syndrome is currently lacking and further research is 

needed. 

Catastrophic disturbance 

Montserrat is subject to both hurricanes and 

volcanic eruptions. Both of these are of course natural 

events, which have occurred throughout Montserrat’s 

history, and one would therefore expect the fauna and 

flora to be resilient. However, such events now occur in 

an anthropogenically modified landscape. For example, 

much of Montserrat’s forest (though relatively little of 

the hill ranges) has been cleared for human activities, so 

the natural habitat blocks are smaller and more isolated. 

This may make populations more vulnerable to 

extinction because they are smaller and less able to move 

between refugia. Secondly, a number of invasive alien 

plant and animal species have been introduced to the 

island since human colonisation. Typically, successful 

alien species are opportunists, adept at exploiting 

disturbed areas. Thus, the disturbances caused by 

hurricanes and eruptions may enhance the spread of 

alien species in modern Montserrat, with detrimental 

effects on native wildlife. 

Hurricane Hugo, one of the most powerful 

storms in Caribbean history, passed directly over the 

island in October 1989, with massive impacts on human 

society. There were also enormous ecological effects, 

with defoliation of forests, and substantial tree‐fall. 

Interestingly, there was some anecdotal evidence that 

the steeply incised valleys of the hill ranges served as 

refugia because defoliation in these more sheltered areas 

was less severe. 

The ongoing eruption of the Soufrière Hills 

volcano since 1996 has caused many major ash‐falls in 

the Centre Hills, as well as acid rain. During late 1996 to 

early 1998, ashfalls were very frequent. After this 

period, ash‐falls tended to be more infrequent one‐off 

events (e.g. in July 1998, 2001 and 2003), although 

absolute quantities of ash deposited were vast. Forest 

bird monitoring data indicates that many bird species 

showed substantial declines in the months following 

major ash‐falls (Dalsgaard et al., 2007). However, these 

declines were neither catastrophic nor long‐lived, with 

recovery in subsequent years. Overall, most forest bird 

populations were at least as numerous in 2005 as in the 

early stages of the eruption in 1997 (though pre‐eruption 

densities are not known). There is good evidence that 

arboreal arthropod populations are significantly 

depleted by ash‐falls (Marske, 2004). However, these 

effects are short‐lived – perhaps of the order of a few 

months. This suggests a mechanism for the observed 

declines in bird species following ash‐falls: a marked but 

short‐lived reduction in arthropod food availability. 


The specific risks posed by anthropogenic climate 

change to the Centre Hills ecosystem are largely 

unknown. However, the predicted significant and rapid 

shifts in temperature and precipitation patterns clearly 

could have a major impact on the Centre Hills. As has 

been observed elsewhere, the impacts of climate change 

are likely to first occur in animal and plant communities 

at higher elevations. This is a particular concern, since 

the area of land at high elevations is naturally small. 

The potential increase in frequency and strength of 

extreme weather events, such as hurricanes, poses 

another obvious risk. 

_______________________________________________________________________________________________________________________ 


36

Threats – Conclusions 

In refreshing contrast to many forest areas in the 

tropics, Montserrat’s Centre Hills do not appear to be in 

imminent danger of conversion for human use. Of 

much greater immediate concern is historic, ongoing 

and perhaps accelerating degradation by alien invasive 

species. Urgent attention to the potentially catastrophic 

threat to the forest from feral pigs is required. 

Catastrophic natural events, while a natural 

feature of Caribbean islands, are also a major risk to 

biodiversity. If more than one negative factor (unusual 

precipitation, hurricanes and volcanic eruptions) occurs 

close together in time, then populations with limited 

ranges are clearly vulnerable to extinction. 

A crucial point to note is that any assessment of 

threats to the Centre Hills is severely limited by lack of 

monitoring data. There are no historical data‐sets, or 

current monitoring programmes which permit changes 

in forest cover, forest habitat types, or alien species to be 

detected. Even weather data, which might elucidate the 

relationships between climate and population trends, 

are scarce due to the disruption caused by the volcanic 

crisis. This lack of monitoring is a significant threat in 

itself, since any negative population trends in key 

species cannot be diagnosed and rectified. An 

integrated pressure‐state‐response monitoring scheme is 

urgently required. 

2.2.2. The Centre Hills management plan project 

Since its inception, the CHBA has become a major 

component of the Centre Hills Project (CHP), a UK 

Government Darwin Initiative‐funded project which is 

working to achieve the goal of “enabling the people of 

Montserrat to effectively manage the Centre Hills and 

associated resources” for biodiversity conservation and 

sustainable natural resource use. The key activities of 

the project include institutional capacity building, 

training, a socioeconomic assessment, legislative review, 

outreach programme, ecological research as well as the 

CHBA. The CHP commenced in June 2005 and is due to 

run to March 2008. It is a collaboration of the Ministry 

of Agriculture, Lands, Housing and The Environment 

(MALHE), Royal Society of the Protection of Birds 

(RSPB), Royal Botanic Gardens, Kew (RBG‐Kew), 

Montserrat National Trust (MNT), Durrell Wildlife 

Conservation Trust (Durrell) plus the Montserrat Tourist 

Board. Information on how biodiversity is distributed, 

the status of species of conservation concern, and threats 

to biodiversity is needed to help set conservation 

priorities and inform the design of a Management Plan 

and Protected Area for the Centre Hills. 

2.2.3. National and international obligations to 

biodiversity conservation 

The CHBA (and CHP) will help Montserrat meet 

its national and international obligations for biodiversity 

conservation and sustainable natural resources use. 

These obligations include Montserrat’s Environmental 

Charter obligation “To safeguard and restore native species, 

habitats and landscape features, and control or eradicate 

invasive species”. It will also help achieve one of the ‘St. 

Georges’ Declaration Of Principles for Environmental 

Sustainability in the Organisation of Eastern Caribbean

States’ to protect plant and animal species; “The flora and 

fauna and the ecosystems of the region will be conserved and 

protected. At the same time, the people and authorities must 

prevent the introduction of alien and modified species which 

may have a negative impact on the environment and their 

health. Endangered species and their habitats will be secured 

and protected.” The Convention on Biological Diversity 

(CBD) obliges countries to adopt a National Biodiversity 

Strategy and produce Action Plans for the conservation 

of biodiversity and the sustainable use of the 

components of biodiversity. Scientifically robust 

information on the status, value and endangerment of 

biodiversity of the Centre Hills will underpin the 

development of such strategies, targets and action plans. 

Although Montserrat has to date not yet acceded to the 

CBD, the MALHE expects completion of this process in 

the near future and it is one of the highest priorities of 

the newly established Department of Environment 

(DoE). 

2.3. Scope of the project 

2.3.1. Project objectives 

The primary objectives of the CHBA project were to: 

• inventory the biodiversity of the Centre Hills, 

Montserrat, by collating existing data and 

sampling a number of indicator taxa, including: 

• plants and habitats 

• invertebrates, with emphasis on beetles 

(Coleoptera) 

• amphibians 

• reptiles 

• birds 

• bats 

• evaluate the status of species of particular 

biodiversity value and conservation concern, 

• map spatial patterns in biodiversity and 

important sites for key species to identify ‘key 

biodiversity areas’, 

• produce a classified habitat map of the Centre 

Hills, 

• assess the threats posed by invasive plants, 

• assess the status of introduced black and brown 

rats and their potential impact on indigenous 

flora and fauna, 

• provide a baseline biodiversity dataset and data 

collection protocols for future monitoring, 

• make recommendations for conservation 

priorities within the Centre Hills, and the 

management requirements of species and habitats 

of biodiversity value and conservation concern, 

and, 

• build capacity in MALHE for the design, 

implementation and analysis of biodiversity 

assessments and ecological surveys. 

2.3.2. Research design 

The indicator taxa outlined above were sampled 

at 28 sample points (CHBA points) distributed randomly 

across the Centre Hills (randomly selected from the 149 

sample points used for the Montserrat Forest Bird 

Monitoring Programme), but stratified by altitude so 

that each 100m altitude band was sampled in proportion 

to its area (Fig. 2.8). Two additional points were 

established outside of the immediate vicinity of the 

Centre Hills, in order to increase the sampling effort in 

dry forest habitat. This ‘stratified random design’ was 

employed to obtain an unbiased and representative 

sample of the biodiversity of the Centre Hills. This 

formal study was supplemented by the collation of 

historical data, analysis of previous plant and insect 

collections, recording incidental observations and ad‐hoc 

surveys of areas of particular interest. The teams of 

experts visited each CHBA point on one or more 

occasions to carry out data collection; methods for 

different taxonomic groups are outlined in the relevant 

chapters. A number of additional sample points were 

established and visited as part of the plant survey to 

collect data in order to ground‐truth a habitat map (see 

Chapter 3). Plants, amphibians and reptiles were 

surveyed in the wet season of 2005 and the dry season of 

2006. Invertebrates, bats and rats were surveyed during 

the wet season of 2005 only. 

Data on bird diversity was supplied from the 

MALHE/RSPB‐led Montserrat Forest Bird Monitoring 

programme. This programme has run since 1997 and 

has produced a large body of information on the 

avifauna of the Centre Hills. Details of the design of the 

Montserrat Forest Bird Monitoring programme and 

associated data collection protocols are given in Box 5. 

Additionally, the CHBA project was also able to utilise 

information collected by Scott Pedersen and team from 

South Dakota State University (SDSU) as part of a long 

term (1978‐) bat monitoring programme on Montserrat. 

2.3.3. Project outputs 

The outputs of the CHBA project will be as follows: 

• A published technical report 

• A biodiversity database linked to the 

Montserrat’s national Geographical Information 

System (GIS) held on the MALHE computer 

network 

• A vegetation map of Montserrat 

• A minimum of two articles published in peerreviewed 

scientific journals 

• Strengthened biodiversity assessment and 

monitoring skills in MALHE and MNT

3. Plants and habitats of the Centre Hills and Montserrat 


3.1. A brief history of botanical collection in 


Compared to other islands in the Caribbean, 

Montserrat has received little botanical exploration. The 

earliest botanical collections made in Montserrat were 

by John Ryan in the late eighteenth century. He lived 

and worked on the island as a physician and a 

plantation owner for several years. During this time, 

Ryan collected the type specimen of the small tree 

Xylosma serratum, endemic to Montserrat. Most of his 

collections are held in the Copenhagen Herbarium in 

Denmark, his home country. 

The West Indies received notable botanical 

studies in the form of two important Floras between the 

late eighteenth and mid nineteenth centuries – Swartz’s 

Flora Indiae Occidentalis (1797) and Grisbach’s Flora of the 

British West Indian Islands (1859‐1864). Although these 

works were important in the context of the West Indies 

and specifically for the British Territories, they lack 

detailed botanical information pertaining to the flora of 


The 20 th century brought new botanical explorers 

to Montserrat; however, the majority of these explorers 

spent little time on the island. Based on the collections 

held in the Kew Herbarium, the following botanists 

collected in Montserrat during this era: Robson, W. 

between 1907‐1911; Squire, F.A in 1937; Beard, J.S. in 

1944; Proctor, G.R. in 1959; Price, W.R. in 1969; Adams, 

Bryan R. in 1976‐1977; and Brussel, D. A. in 1977. 

It was not until 1979 that an extensive checklist 

was produced of the flora of Montserrat. This was 

achieved as part of Richard Howard’s work to produce 

the Flora of the Lesser Antilles (1979). This is currently the 

most important and comprehensive botanical inventory 

of Montserrat and the other islands in the Lesser 

Antilles. 

During the current effort to record Montserratian 

collection information held at Kew, and Howard’s 

collections recovered from the old Botanical Station in 

Plymouth, in the UK Overseas Territories Species and 

Specimens Database [BRAHMS software, http:// 

herbaria.plants.ox.ac.uk/bol/home/], only a few 

examples from the Centre Hills were noted. The 

majority of herbarium specimen collections over the 

years appear to have been made in the southern part of 

the island. This is a useful record of what may have 

been lost to the volcano; however, it highlights the lack 

of botanical knowledge for the rest of the island, 

particularly the Centre Hills. 

3.2. Data collection methods and progress 

The aim of the plant survey within the 

biodiversity assessment was to gather baseline 

information on the flora of Montserrat (to supplement 

Howard’s checklist), map the major vegetation types 

that occur across the island and investigate patterns in 

plant diversity within the Centre Hills. This is being 

achieved though the collection of plant specimens and 

seeds, site records, and vegetation surveys throughout 

the Centre Hills, including at the 30 CHBA points. 

Different habitats are visited to develop a wider 

knowledge of plant species composition. Additionally 

time is spent in other areas of the island, such as the 

Silver Hills, so as to increase the understanding of the 

island’s different ecosystems and species that occupy 

these areas. 

Herbarium specimen collections are made 

according to the methods outlined in The Herbarium 

Handbook (Bridson & Forman, 1998). In general, 

specimens in flower and/or fruit are collected to increase 

the likelihood of a fully determined specimen. Where a 

species has been previously collected and determined, a 

“Site Record” is made. In this case no plant material is 

collected; however, locality notes, GPS coordinates, and 

habitat details are recorded. This provides a better idea 

of particular habitats that are preferred by certain 

species and enables calculation of a species extent of 

occurrence. Site Records are also important in tracking 

the spread of invasive species. 

Special collections can be made, such as 

germplasm collections. For example, seeds were 

collected of two endemic species from Montserrat for 

long‐term storage. Seed collection procedures follow the 

Millennium Seed Bank guidelines. The full publication 

can be found at www.kew.org/msbp/internat/ 

fieldmanual.html. 

All of the records that are made in the field are 

directly entered into a PDA‐GPS (http:// 

www.garmin.com/products/iQueM5/) and later 

uploaded to the UKOTs Species and Specimens 

Database. Plant species collections, site records and 

habitats are, in general, photographically documented. 

All data collected are repatriated to Montserrat through 

the Physical Planning Department (PPD) as part of the 

national GIS. 

The initial assessment of plant diversity has 

provided baseline data on species composition, habitat 

structure, and given clues to habitat preferences of some 

species and allowed vegetation and habitat indicators to 

be identified. Many of the plant species recorded at 

CHBA points were not in flower or fruit when the initial 

assessments were undertaken. The presence of 

flowering and/or fruiting material is vital for accurate

identification to the species level. Consequently many 

plant taxa remain identified to family or genus level 

only. In some cases identification was not possible even 

to the family level and these taxa remain unknown. 

Monitoring of the CHBA points will continue until firm 

identifications are possible. 

At each of the CHBA points, data on a number of 

variables were recorded. These data have been analysed 

to determine the structure (e.g. species presence at 

ground layer, understory and canopy) of the different 

forest types (see section 3.3 for description of forest 

types), species composition and richness within forest 

types, and to determine differences in elevation and 

slope amongst the forest types. Summary data are 

shown in Figures 3.1 and 3.2. 

Three major collecting field trips have been 

undertaken since the CHBA started (November 2005, 

February 2006 and May 2006). Data from the database,

numbers of the collections made during these months. 

Depending on the type of plant, special 

collections are sometimes necessary to ensure 

appropriate material is available for taxonomists trying 

to name species. Special collections such as Carpological 

and Spirit Collections are made for plants with bulky 

fruits and delicate flowers, respectively. DNA 

collections can also be made for species of particular 

interest so that researchers can compare similar species 

or determine genetic diversity amongst populations. 

Leaf samples for DNA analysis are collected into silica 

gel to preserve the DNA. 

3.3. Diversity and status of plants in Montserrat 

3.3.1. The Montserrat plant species checklist 

To meet the need for baseline data on 

Montserrat’s plant diversity, a working species checklist 

for the island has been produced (see Appendix 1). A 

wide range of information sources have been consulted 

to make use of existing information including floras (in 

particular Howard’s Flora of the Lesser Antilles), 

checklists, monographs, and via personal 

communications. Species that have been verified to 

occur on Montserrat (i.e. via determined herbarium 

specimens) were added to the species checklist. 

Sightings by Kew’s UKOTs Programme staff and 

records from other sources indicating the possibility of a 

species occurring on Montserrat were added as 

‘candidate’ species to the list. These species will be 

confirmed on the checklist once herbarium specimens 

have been collected from the island and been positively 

determined. All data will be added to the UKOTs 

Species and Specimens Database (UKOTs Database). The 

full checklist will also be made available through the 

UKOTs website on the main Kew server (www.kew.org) 

and through BRAHMS On‐Line (www. 

herbaria.plants.ox.ac.uk/BOL/). 

All plant voucher specimens are deposited in the 

Kew Herbarium (K). Duplicates have been collected 

that can be repatriated to Montserrat once facilities have 

been established to house them. 

Species list categories 

Accepted plant Family, Genus, and Species 

names (including subspecies, varieties etc.) are used at 

all times. Species names are qualified by their 

appropriate authors. Common names are listed but 

emphasis is given to ‘local’, Montserratian, names. 

Common names are derived from published sources e.g. 

Howard (1979) whilst local names have been gathered 

from Montserratians during the current fieldwork 

programme. Information regarding species life‐form and 

_______________________________________________________________________________________________________________________

dimensions is provided along with, in some cases, key 

identification features. Species habitat information is 

entered into the list if available. A notes field is added to 

capture other relevant information (e.g. useful historical 

information, known localities, etc.). All information 

sources are referenced accordingly for each species 

entry. In general, the species list categories follow the 

layout of any standard species checklist. However, there 

are a number of important categories (listed below) that 

need special mention in this case. 

Plant category 

Each species is given an identification code and is 

assigned to one of the following categories: 

Dicotyledons (Dicots), Monocotyledons (Monocots), 

Pteridophytes, or Gymnosperms. This is particularly 

useful for the production of field lists. 

Biogeography 

The bio‐geographical categories are as follows: 

• Endemic to Montserrat: species range restricted 

to Montserrat. 

• Endemic to the Lesser Antilles: species range 

restricted to the Lesser Antilles (as defined by 

Howard (1979) the islands from Anguilla in the 

north to Grenada in the south and Barbados in 

the east). 

• Restricted range: species range exceeds Lesser 

Antilles but is restricted to a small area outside 

the Lesser Antilles. 

Antilles, Bahamas archipelago, Trinidad and 

Tobago. 

• Peri‐Caribbean: species range exceeds Caribbean 

but is restricted to a small continental area. 

• Wider distribution: species range exceeds all of 

the above geographical categories. 

• Introduced: denotes that a species is introduced, 

i.e. ornamental/ food crop/ invasive, etc. 

‘Lesser Antilles Distribution’ and ‘Distribution’ Fields 

The Biogeography of a species is generated from 

information held in the fields Lesser Antilles Distribution 

and Distribution and they provide further information 

for the red‐listing and conservation planning process. 

The Lesser Antillean Island chain are listed north to 

south in the following order: Anguilla, St. Martin, St. 

Barthelemy, Barbuda, Antigua, Saba, St. Eustatius, St. 

Kitts, Nevis, Redonda, Montserrat, Guadeloupe, La 

Desirade, Marie Galante, Les Saintes, Dominica, 

Martinique, St. Lucia, St. Vincent, the Grenadines, 

Grenada, Barbados. The field Distribution is used if a 

species range exceeds that of the Lesser Antilles. 

Cultivated 

A cultivation category is provided if a species is 

under cultivation on Montserrat (i.e. ornamental, food 

plant, medicinal herb, culinary herb, environmental use 

[sand stabilization, wind break], etc). This information 

may lead to and assist in further ethno‐botanical study 

or for targeting potentially invasive species.

Invasiveness 

Information is being compiled on known and so 

far unreported introduced (non‐native) plant species 

occurring in Montserrat. These species are being 

monitored by Kew’s UKOTs Programme staff and local 

project partners during field trips and are rated 

according to the degree to which they threaten native 

plant species and habitats. The following categories are 

used to rate species’ invasiveness: 

• Naturalized 

• Naturalized and spreading 

• Invasive 

Summarised totals 

The total number of verified species for 

Montserrat is 941 (see Table 3.3). Of these, three are 

known endemics to Montserrat, 70 are endemic to the 

Lesser Antilles, and another five species’ ranges exceed 

the Lesser Antilles but are restricted to a small area 

outside the Lesser Antilles. Potentially, Montserrat is 

home to 78 plant species of global conservation concern. 

These 78 restricted‐range species comprise the 

Candidate Red List (see Box 1) and will be the focus of 

investigation in the next phase of botanical work 

following the CHBA. 

3.3.2. Threats to Montserrat’s flora 

Threats to the flora of the Centre Hills are mainly 

restricted to feral mammals. Both pigs and rats are of 

major concern due to rooting up of vegetation by pigs 

and loss of seeds/seedlings to rats. On the periphery of 

the Centre Hills, clearance of vegetation for rural and 

urban development is a potential threat as this 

disturbance often breaks the contiguous forest, alters 

water tables/courses, causes erosion/silting, and allows 

access for non‐native species. 

Invasive alien species (IAS) are a major threat to 

the native biodiversity throughout the world and a 

recent review has highlighted their impacts in UK 

Overseas Territories (Varnham 2006). This review also 

highlighted the gaps in our knowledge of the current 

status of IAS and their impacts at a local level. Little 

information exists on the nature of the invasive plant 

threats in Montserrat and this situation is being 

addressed within the current project. An invasiveness 

field has been introduced to the Montserrat Species 

Checklist. Data to populate this field are being drawn 

from several sources: 

• Published species information to highlight 

species that are known to be non‐native to 


• Published sources of known invasive species (e.g. 

The Global Invasive Species Programme 

(www.gisp.org); the Invasive Species Specialist 

Group (www.issg.org); Florida Exotic Pest Plant 

Council (www.fleppc.org)). 

• Personal knowledge of invasive species in other 

Caribbean islands 

149 plant species are verified as having been 

introduced to Montserrat. There are another 45 species 

that are candidates, but not yet verified through 

herbarium specimens (See Appendix 3 for a full list of all 

non‐native species recorded from Montserrat). These species 

are being examined to determine which category of 

invasiveness they are best assigned to. 

The major invasive plant threats on Montserrat 

are currently outside the Centre Hills (as defined by the 

current 11.16 km 2 forest feserve boundary) with 

relatively little evidence of invasive plants presenting a 

major threat within the core areas of the Centre Hills. 

However, in areas outside the Centre Hills several 

aggressive invasive plant species have established 

themselves and are negatively impacting the native 

biodiversity. The main effects are the replacement of 

native biota. 

Within the Centre Hills forest reserve 

Two key alien species have been identified that 

are being monitored by RBG‐Kew & MALHE Staff: 

• Spathoglottis plicata, an invasive ground orchid 

that is becoming well established within the 

Centre Hills and has been recorded in several 

forest types, including in Elfin Woodland at the 

top of Katy Hill. Originally from Asia this species 

is thought to have escaped from cultivation in 

Puerto Rico and is gradually spreading 

throughout the Caribbean. No major negative 

impacts have been observed yet, but this species 

has the potential to crowd out native species 

especially in fragile habitats like Elfin Woodland. 

• Psidium guajava, (guava), an escaped tree of 

cultivation that is spreading rapidly outside the 

Centre Hills (e.g. Richmond Hill) and has been 

recorded within the Centre Hills. This plant is a 

major invasive species in many parts of the 

World. It has the potential to become a major 

threat to the habitats of the Centre Hills where 

abandoned plots of guava can quickly spread 

into other disturbed areas caused by feral 

mammals and volcanic activity. 

Outside the Centre Hills forest reserve 

Three key alien species have been identified and 

are being monitored: 

• Casuarina equisetifolia (Australian pine), a large 

tree originally from Australia and the Indo‐ 

Pacific. It has been planted throughout the 

tropics as a shade tree and is a major invasive 

problem. It grows particularly well and is freeseeding 

along the coast and in recently deposited 

volcanic ash deposits. 

_______________________________________________________________________________________________________________________ 


44

• Cryptostegia madagascariensis (known locally as 

purple allamanda), a vigorous scrambling shrub 

and escapee of cultivation. Originally from 

Madagascar, it is widely planted for ornamental 

purposes, especially as an effective and colourful 

hedge. This species is covering large tracts of 

land in the Silver Hills where it grows almost as a 

monoculture at the expense of all other species. 

• Psidium guajava, (guava) – see above. 

3.4 Patterns in plant diversity within the Centre 

Hills: Implications for biodiversity conservation 

3.4.1. Island endemic species 

Three plant species have been identified as 

strictly endemic to Montserrat: Rondeletia buxifolia, 

Epidendrum montserratense and Xylosma serratum and as 

such represent the most important plant species of 

global conservation concern and require the most 

stringent conservation protection measures. 

• Rondeletia buxifolia Vahl (Fig. 3.3) is a small shrub 

in the Rubiaceae that has so far only been found 

outside the current Centre Hills forest reserve 

boundary. This species must currently be 

considered as extremely vulnerable as it enjoys 

no protection at either the habitat or species level. 

During the course of this project significant 

populations of this plant have been lost to 

clearance of forest habitat for development. 

Although a formal red listing has yet to be 

completed, its candidate status is Critically 

Endangered, the highest level of threat of 

extinction recognized by IUCN. An initial seed 

collection was undertaken in May 2006 and the 

seeds are stored in the Millennium Seed Bank at 

Kew – Wakehurst Place. Cuttings have been 

established in ex situ cultivation in the 

conservation nursery at the Montserrat National 

Trust. 

• Epidendrum montserratense Nir (Fig. 3.4), an 

epiphytic orchid that seems to be largely found 

on veteran mango Mangifera indica trees and 

sugar mill ruins outside the current Centre Hills 

forest feserve boundary. Like R. buxifolia this 

species must also be considered as extremely 

vulnerable as it also enjoys no protection at either 

the habitat or species level and as such also has a 

candidate red list status of Critically Endangered. 

An initial seed collection was undertaken in May 

2006 and the seeds are stored in the Millennium 

Seed Bank at Kew – Wakehurst Place. Plants 

rescued from dead mango trees in the Belham 

Valley have been established in ex situ cultivation 

in the botanic garden at the Montserrat National 

Trust. 

• Xylosma serratum Urb is a small tree in the 

Salicaceae that is only known from one location

(Grisebach 1859‐1864; Howard 1979). Since this 

site was destroyed by a major pyroclastic flow 

during the 1995‐1997 volcanic eruptions we 

consider this species to be Extinct. However, 

since there are similar habitats to Great Alps Falls 

in the Centre Hills it is possible that this species 

exists there, but explorations so far have failed to 

find it. No ex situ material of this species exists so 

the only evidence we have are herbarium 

specimens. 

3.4.2. Other important plant species 

The on‐going fieldwork and analysis of these 

data has identified a number of other plant species of 

potential conservation concern. Three notable examples 

are: 

• Veteran mango trees (Mangifera indica), 

particularly in the Belham Valley area which 

provide the major location of the endemic 

Epidendrum montserratense. Careful consideration 

needs to be given to the long‐term protection of 

these trees 

• Montserrat’s only native gymnosperm, 

Podocarpus coriaceus, is listed in the IUCN Red 

List of threatened species as Lower Risk (Conifer 

Specialist Group, 1998). More information is 

required to re‐assess this species which is on the 

Candidate Red List. An important stand of large 

mature trees has been identified on the top of 

Hope Ridge highlighting the conservation value 

of this ridge within the Centre Hills. 

• Three tree species that have been widely utilised 

for timber throughout the region are native to 

Montserrat: Cedrela odorata (stinking cedar), 

Swietenia mahagoni (West Indian mahogany), and 

Guaiacum officinale (lignum vitae). In many 

countries in the region these species have been 

over‐exploited and as a consequence are all listed 

as threatened species by IUCN‐The World 

Conservation Union (Oldfield et al 1998). S. 

mahagoni and G. officinale are Endangered and 

listed on Appendix II of CITES; C. odorata is 

Vulnerable and listed on Appendix III of CITES 

(www.cites.org). A fuller evaluation of the 

distribution of these species needs to be 

undertaken and an action plan for their 

conservation developed. 

3.4.3. Habitat diversity 

A survey of the island’s vegetation has been 

underway since November 2005. Field data collection 

has taken many forms. Most notable are herbarium 

specimen collections with associated habitat data, CHBA 

surveys, and Vegetation Assessment Point surveys. 

Herbarium specimen collections are made when a new

species is encountered or a previously observed species 

is found exhibiting new characteristics (e.g. fruiting). 

The CHBA Point surveys are undertaken at 30 agreed 

points within the Centre Hills at least once within the 

first year of the project. Vegetation Assessment Point 

surveys are undertaken in the field when a transition of 

habitat is noticed (e.g. Dry Forest changes to Mesic 

Forest) or land use changes (e.g. abandoned agriculture 

plot, area cleared for development). A series of 

standardised forms have been produced by Kew’s 

UKOTs Programme staff to record habitat and 

vegetation data directly into a database file held on a 

PDA‐GPS. These files are later uploaded, compiled, and 

used in association with Maxent prediction software

Table 3.4 Contd. Land Cover descriptors detailing habitat types and indicator species 

(http://www.cs.princeton.edu/~schapire/maxent/) to 

generate potential vegetation distribution maps. 

The production of an island wide vegetation map 

will allow for a better understanding of the distribution 

of Montserrat’s plant species. This will be part of the 

final map production for the Centre Hills project and 

will include maps showing forest types, habitat 

disturbance, threatened species and invasive species 

distributions, and major land features (e.g. roads, trails, 

boundaries, water courses). Accompanying the maps 

will be a detailed description of the process undertaken 

to generate those maps and the data gathering and 

analysis. 

The vegetation of Montserrat is extremely varied 

due to the volcanic origin of the island. Several microclimates 

are found on the island due to geology, aspect, 

elevation, precipitation, and land use (mainly historic). 

These micro‐climates give rise to several different 

vegetation types. The different vegetation types are 

often home to plants that have adapted to these microclimates 

and are very specialized. The converse of this 

scenario is much more common where plant species are 

found growing across several different vegetation types; 

therefore, the structure and composition becomes very 

important in determining the type of vegetation/land 

cover. Table 3.4 is derived from observations made 

whilst undertaking field work on Montserrat. 

Once the Land Cover Descriptors were keyed 

and defined they were used to record the vegetation 

types on the island. For the Centre Hills, only forest 

types are of concern for the first draft of the vegetation 

map and these will need to be ground truthed to 

confirm boundaries before the map has more detail 

added (e.g. abandoned farmland, ponds, etc). Figure 3.8 

is a map of the Centre Hills vegetation cover showing 

the distribution of the various forest types identified. 

The Centre Hills ecosystem provides a range of 

habitats that are suitable for most of the species 

currently recorded on the Montserrat species checklist. 

In principle once the project is complete the Centre Hills 

species checklist could look very similar to the current 

Montserrat species checklist. However, the current forest 

boundary encompasses very little dry forest and no 

littoral forest. This means that threatened species that 

are restricted to dry forest (e.g. Swietenia mahagoni and 

Guaiacum officinale) currently have little protection and 

species restricted to littoral forest (e.g. Rhizophora mangle) 

currently have no protection. In addition to the underrepresentation 

of dry and littoral forest types within the 

existing forest reserve boundary, reference has already 

been made to the fact that all documented populations 

of the E. montserratense and R. buxifolia are outside the 

current reserve designation (Figs. 3.6 & 3.7). 

A key management objective for plant diversity 

in the Centre Hills is to ensure that all forest types and 

species occurring in those forest types are adequately 

represented within the protected/managed area. Steps 

need to be taken either to bring the locations supporting 

populations of E. montserratense and R. buxifolia within 

the protected area or for alternate species level

protection measures to be introduced. Other 

management measures that need to be introduced 

include: active conservation for threatened species; 

control of invasive plant species, especially in fragile 

habitats like Elfin Woodland; control of feral mammals, 

especially pigs and rats; and limiting the spread of 

abandoned crops (e.g. guava, mangos, bananas, 

coconuts). 

There is no doubt that the Centre Hills comprise 

a dynamic mosaic of habitats which support a wide 

range of plant species including many species of 

restricted distribution, two single island endemics as 

well as several threatened species. As such this would 

qualify the Centre Hills as an Important Plant Area 

(IPA) as defined by the Important Plant Area 

programme co‐ordinated by Plantlife International and 

IUCN‐The World Conservation Union (Plantlife 

International 2004). The long‐term protection of the 

Centre Hills would be an important contribution to the 

implementation of Target 5 of the Global Strategy for 

Plant Conservation – ‘Protection of 50% of the most 

important areas for plant diversity assured’ (CBD, 2003). 


The UK Overseas Territories Programme at Royal 

Botanic Gardens, Kew would like to thank everyone 

who has contributed to the plant components of the 

Montserrat Biodiversity Assessment. It’s been a 

remarkably collaborative and enjoyable journey. In 

particular we would like to pay special thanks to our 

field colleagues in Montserrat: Calvin “Blacka” Fenton, 

Jervain Greenaway, Phillemon “Mappie” James 

“Scriber” Daley, James “Boatswain” Boatswain, Lloyd 

“Lloydie” Martin, & John “Gamby” Martin. Without 

their in depth knowledge of the Centre Hills and 

commitment to fieldwork this assessment would have 

not been possible. 

Special mention goes to Carole McCauley, 

Darwin Project Manager, and Steven Mendes, Darwin 

Project Counterpart for all their logistical support and 

facilitation which ensured that all our visits to 

Montserrat were both successful and enjoyable. Thanks 

to Gerard Gray, Director, Department of Environment, 

for all his support since the establishment of the 

Department; to Claude Gerard, former Director of 

Agriculture, for making the initial assessment work 

possible; to Lady Eudora Fergus, Executive Director 

Montserrat National Trust for enabling Mappie to 

participate in the fieldwork and to Lavern Rogers, 

Physical Planning Unit, for her assistance with GIS 

related issues. Thanks to the Governor and staff of the 

Governor’s Office on Montserrat for their continuing 

support for all our work in Montserrat. 

Thanks to Richard Young for his tireless efforts to 

edit and chase contributors for their input. Many thanks 

to all our colleagues at RBG Kew, particularly in the 

Herbarium, who have given of and are still giving their 

time to identify and verify our Montserrat plant 

specimens and to the completion of the plant species 

checklist. 

And finally many thanks to the many friends, 

accommodation providers and restaurateurs who made 

our stays in Montserrat so agreeable.

4. Invertebrates of the Centre Hills and Montserrat, with an 

emphasis on beetles 


4.1. Introduction 

About three quarters of the world’s known organisms 

are animals (Fig. 4.1). Invertebrate animals 

alone make up the vast majority of the world’s biodiversity, 

the Arthropoda make up the vast majority of the 

invertebrates, the Insecta the vast majority of the arthropods, 

and the beetles the major portion of the insects 

(Fig. 4.1). In fact, one in 4 described animal species, and 

one in 5 organisms, is a beetle. 

The remainder of the animals, the vertebrates and 

their relatives, are a minor, tiny slice of the total biodiversity 

pie, and if the terrestrial vertebrates (i.e. nonfishes) 

are treated separately, they would virtually disappear. 

Although, because of their size and economic 

importance as food, tourist attractions and pets, they are 

the animals most familiar to the public, on a biodiversity 

scale, they are nearly insignificant. 

The number of terrestrial animal species native to 

Montserrat is probably several thousands, but the most 

extensive summary of the fauna to date (Stevens and 

Waldmann 2001) records only 53 tetrapods and 318 specific 

records for invertebrates on Montserrat (Table 4.1). 

Unfortunately, the vast majority of species present on 

Montserrat, and especially those populations of global 

conservation importance in terms of unique, endemic 

elements, are either poorly or not at all documented. 

The biodiversity of Montserrat is undoubtedly vastly 

more expansive than one would expect from a quick 

glance at a globe, but the scientific literature does nothing 

to indicate this fact, which under-values Montserrat’s 

biodiversity. 

This chapter will attempt the near impossible 

task of documenting the terrestrial invertebrate fauna of 

Montserrat, focusing on the Centre Hills. The data we 

have assembled and present below will show that the 

invertebrate fauna of Montserrat, concentrated mostly in 

the Centre Hills, ranks the island globally as among the 

most important areas in terms of density of unique, rare, 

valuable and endangered biodiversity. We hope to provide 

the jumping-off point for a discussion of this amazing, 

and still mostly unknown biodiversity, and the impact 

that increased knowledge can have on the status of

a small but biotically rich territory. We also give a general 

discussion of the historical data available, the history 

of exploration of Montserrat’s fauna (see Box 3), and 

some of the challenges faced whilst conducting the invertebrate 

inventory (see Box 2). We concentrated much 

of the effort of the inventory on the Coleoptera (beetles) 

as the primary example to illustrate the importance of 

the Centre Hills and the need for its recognition as a 

conservation priority. 

In an appendix to this report, we provide species 

lists of, and notes on, the beetles, the non-beetle hexapods 

(Insects), and the non-hexapod invertebrates of 

Montserrat. Also provided is a full Coleoptera checklist. 

4.2. Diversity of the Montserrat invertebrate 

fauna 

4.2.1. Results from pre-2000 collecting 

In all historical collections (see Box 3 for detailed 

discussion), except Bass and Stevens and Waldmann, the 

vast majority of specimens originated from south of the 

Belham Valley. It was clear that the big draw for most 

visitors was the Soufrière, and the high areas there, plus 

the area around Plymouth and the road to the south 

which were the most heavily sampled. The little bit of 

material coming from north of the Belham was from 

Woodlands. For instance, Blackwelder’s northernmost 

sites are at Woodlands and Trant’s beach. The 

Baranowskis made three long visits to Montserrat, making 

theirs perhaps the single greatest effort of any entomologist 

before 2000, but Slater & Baranowski (2005) 

report not a single specimen from the Centre Hills. Only 

the Aitken group, and possibly Fennah, spent much if 

any time in the north and only Fennah seems to have 

actually penetrated the mid-to-high elevations of the 

Centre Hills. 

The problem with this approach is that while the 

highest, wettest and most fertile point on the island before 

the volcanic crisis was in the southern mountain 

series, that area was in fact, secondary forest, which has 

relatively recently regenerated from both agricultural 

and historical volcanic activity. This fact was not obvious 

to earlier collectors who followed Darlington’s 

(1943) instruction to head to the tops of the highest 

peaks. Although we now know that the Centre Hills’ 

old forests are rich, possibly only a single one of the insect 

collectors who visited Montserrat between 1894 and 

2000 went to the specialized higher elevation forests of 

the Centre Hills, and that was Fennah. 

The only previous published summary of the 

fauna of Montserrat (Stevens and Waldmann 2001), provided 

a list of invertebrates totalling 455 species, which 

is summarised in Table 4.1. It is noteworthy, however,

that Stevens and Waldmann included records of species 

for Montserrat on the basis of extrapolation. For instance, 

not one of the 11 records of Thysanoptera (thrips) 

they list has actually been recorded from Montserrat - 

they are simply recorded to be widespread in the Lesser 

Antilles. Fully 30% of the invertebrates listed by Stevens 

and Waldmann are not accompanied by a record specific 

to Montserrat (Table 4.1), reducing their recorded total 

confirmed species by 136. That number is further reduced 

by their inclusion of erroneous records and double-listings 

(see below). Of those species listed, most are 

of medical, veterinary, or economic importance (Table 

4.1), and hence the list includes a disproportionate number 

of widespread, exotic and pestiferous species. However, 

this is no fault of Stevens and Waldmann, but is an 

accurate depiction of our unbalanced knowledge of the 

various groups of animals. Erroneous listings and double 

listings as alternative scientific names are simply

unavoidable in a broad general work such as theirs, but 

their frustration at finding no published records of 

groups obviously present on the island understandably 

lead to their use of non-specific records from neighbouring 

islands or the region in general. To the extent possible, 

we have listed all the additions and corrections to 

Stevens and Waldmann (2001) that we have found, but 

undoubtedly many remain. 

From what we have learned whilst reviewing the 

historical data, it is possible that another 100 species’ 

records for Montserrat lie buried in the world’s primary 

taxonomic literature, but given factors such as level of 

taxonomic uncertainty and the low sampling effort of 

the Centre Hills, the recorded fauna of Montserrat is 

clearly but a small fraction of reality. 

4.2.2. Post-2000 collecting history 

In 2000, our group, from the West Indian Beetle 

Fauna Project at Montana State University, began to 

work on Montserrat. Initially, a visit at the invitation of 

the Montserrat Department of Agriculture and the Royal 

Society for the Protection of Birds in June, 2000 included 

Michael Aaron Ivie and Kelvin Antonio Guerrero. The 

impetus was the question of whether Montserrat oriole 

chicks were starving because of the effects of volcanic 

ash on their insect food. Several nesting sites in the Centre 

Hills were visited, although the visit came in an extensive 

dry period, and relatively little was collected. 

Our initial impressions lead to a multi-year project, and 

a return visit in January 2002, by Ivie, Katharine Ann 

Marske and Kenneth Patrick Puliafico. On that visit, in 

anticipation of a return, Bridget Beatty, Ann Krakower 

and her mother, Rosalie Burrows, were recruited to run 

Malaise and ultraviolet-light traps on a bi-weekly schedule, 

from January through July 2002. In May, June, and 

July 2002, Marske, accompanied for part of the time by 

Ivie, began establishing long-term research sites in the 

Centre Hills. Monthly canopy fogging samples were 

taken from 4 sites in the Centre Hills in May-August 

2002, then bimonthly from October 2002 through August 

2003, by staff of the Montserrat Department of Environment, 

including Lloyd Martin, James Boatswain, John 

Martin, James Daley, and Lloyd Aymer. Marske and 

Ivie, accompanied by LaDonna Lynn Ivie, returned to 

the island in May and June, 2003 to continue work. A 

small amount of material was collected in May 2004 during 

a visit by Ivie for a workshop. On most of these trips, 

Philemon Murrain and/or Calvin Fenton worked with 

our collectors, providing access, guidance and advice to 

maximize the collections. 

Most of this work had been concentrated on the 

mid-elevation forest of the Centre Hills, with repeated 

samples at Hope Ghaut, Fogarty, Cassava Ghaut and 

Underwood Ghaut. Other samples were taken around 

Woodlands, at the Beatty house in Cassava Ghaut, Lawyer 

Mountain, Gunn Hill, Jack Boy Hill and various 

other locations around the Centre Hills, as well as by 

trapping at each of the houses used as residences. The 

Beatty house and Riverside House in Woodlands were

reserve 

of particular importance in this regard. Ivie and Marske 

made separate visits of a few hours each by helicopter 

into Roaches, with traps left for the week between. This 

represented the total of our collecting in the south. A 

helicopter lift to the flanks of Katy Hill gave Ivie an 

overnight collecting opportunity in June 2003, followed 

by a hike over the actual top and out via the ridge to the 

north. This gave the first look at the highest and wettest 

elevations on the island. 

With the goal of expanding the area sampled, the 

Ivies brought a new team of students to the island in 

July and August 2005. This team included graduate 

student Ian Andrew Foley, and undergraduates Vincent 

Goodwin Martinson, Patrick Edward Hughley, Levi 

James Lehfeldt, and Robert Anthony Semplet. They 

placed Malaise and ultraviolet traps in areas both wetter 

(Big River, Killicrankie, Jack Boy Hill, Bottomless Ghaut, 

Katy Hill, Fairy Walk) and drier (Furlong, Cedar Ghaut, 

Rendezvous Bay) than those previously sampled. 

[Material collected by this group is labelled “WIBF 

Group” for the West Indian Beetle Fauna Project, rather 

than listing individual names.] At the end of this field 

work, a week was spent by Ivie on Guadeloupe, studying 

pre-volcano collections in INRA. 

The last collecting to be reported here was the 

result of a visit by the American orithologists/ 

odonatologists Fred Charles Sibley (1933-) and Margaret 

Pries Sibley (1936-) in October, 2006. Their collections 

of damselflies and dragonflies are in their private collec-

4.2.3. Results of post-2000 collecting 

The result of all of these collection activities was 

approximately 1 million specimens of arthropods in 

bulk samples. The goal of the biodiversity assessment 

work was more an inventory than an ecological association, 

and establishing within-island distributions for the 

various species will require future work. From these 

samples, a selection of ca. 15,000 specimens was 

mounted and labelled, representing an attempt to extract 

individuals of all the Coleoptera and Orthoptera 

species, and representatives of other Orders as time and 

space allowed. Among 13,044 mounted specimens of 

beetles, there were 696 species (this is lower than the 

total of 718 beetles because of 22 previously collected 

species were not collected in our survey, discussed below). 

The other specimens were scattered among other 

Orders, and mostly remain unstudied. 

During the taxonomic work, we strongly concentrated 

on the Coleoptera, enumerating 81 probable single-island 

endemic beetles. We also managed to add 

many other groups to the known fauna of the island 

(Table 4.2), providing both some specific and general 

records here as well as material of many more for specialists 

to study. Much of the non-beetle material was 

sent to other systematises appropriate to the group. For 

instance, over a kilogram of samples of both spiders and 

ants were sent to specialists for study, none of which are 

reported on here. Already, 31 beetle records, 2 sawfly 

records, 2 scorpion records, and a fly record have appeared 

in the scientific literature based on our material 

(Valentine 2003, de Armas 2005, Chalumeau & Touroult 

2005, Smith 2005, Kung & Brown 2006), and many more 

will do so in the future. We have already raised the 

number of invertebrate species on Montserrat, either 

through our own collections, the study of others, or the 

discovery of previously missed literature records, from 

Stevens & Waldmann’s (2001) 306 to 1,241. Nearly 60% 

of these species are Coleoptera. Among the non-beetle 

Hexapods, which are an order of magnitude less-well 

studied than the beetles, we tallied 32 additional singleisland 

endemics, and a few among the even-morepoorly-known 

non-hexapod invertebrates. Together, 

this compares ten-fold to the 12 endemic invertebrates 

enumerated by Stevens & Waldmann (2001) just 6 years 

ago. A summary of the total known number of species of 

a range of invertebrate taxa is given in Table 4.2. 

Even with a quadrupling of the total invertebrates 

known from Montserrat to over 1,240 species, the 

majority of animal species on the island remain unknown. 

In order to generate such a prediction, we took 

the numbers of species predicted to exist globally

(Chapman 2006), extracted the data for terrestrial animals, 

and proportioned the insect portion of those numbers 

into 6 groups according to the only nearby wellknown 

insect fauna, that of North America (Triplehorn 

& Johnson 2004). Those numbers provided a percentage-of-the-whole 

for each group. We then used the 

mean Chao-1 indicator for total expected beetles, and 

worked backwards from there to find what would be 

expected number of each group if Montserrat’s total 

fauna fit the global proportional model. Obviously this 

is not an exacting analysis, but should be relatively good 

at making broad predictions of what is still missing. At 

the least, it provides a hypothesis for future testing. 

Considering the total list of beetle species for 

Montserrat by number of observed specimens as a single 

collection (Appendix 2), and subjecting it to the Chao-1 

estimator: S * 1 = Sobs + (a 2 /2b), where “Sobs“ is the number of 

species observed, “a” is the number of singletons, and 

“b” is the number of doubles (Chao 1984, Colwell 2005), 

gives an estimate of a mean expected 827 beetle species, 

with a 95% CI of 792-876 (Calculated with EstimateS 

7.5.1, Colwell 2005). This indicates that the current 

count of 718 species is probably about 87% of the expected 

total number of beetles, with a 95% chance that it 

is between 82 and 91% of the total. 

Using this estimate of the total number of beetle 

species, to extrapolate to the entire Kingdom Animalia, 

we predicted a total of 4,146 animal species occur on 

Montserrat. Fig. 4.3 shows the known and predicted 

number of species of animals, broken down into 10 

groups. Only the vertebrates have a full census, and of 

the invertebrates, only the Coleoptera have a majority of 

the expected species discovered. A simple glance at the 

extent of the yellow on the graph gives an excellent feel 

for just how much work remains to be done on Montserrat. 

Given that the majority of rare and endemic species 

are usually discovered in the last half of an inventory, 

the need for further work on Montserrat’s fauna is obvious. 

4.2.4. Results of post-2000 collections - beetles 

The Coleoptera are the largest and most diverse 

Order of living things. The other megadiverse Orders 

are very heavily biased to one or a few trophic levels 

(Lepidoptera as herbivores, Diptera as saprophages, 

Hymenoptera as predators/parasitoids). There are exceptions 

in all of these cases, but the vast majority of 

their species do relatively similar things. Not so for the 

Coleoptera, which are divided among herbivores, 

fungivores, predators, parasites, parasitoids, lignivores, 

saprophages, detritovores, and all the other “vores” you 

can think of, including mosses, algae, slimemolds, carrion, 

dung and more. Their lifestyles include living just 

about everywhere -- at the tops of the forest canopy, in 

leaf litter and the soil; in human houses, bird nests, and 

bee hives; in and on fresh water; inside other animals; on 

salt water beaches and in warm springs; under rocks, in 

the lichens on rocks and where there are no rocks. 

Therefore, the beetle assemblage reaches farther into the 

entire ecosystem than any other group. Plus, we believe 

they are the most beautiful, fascinating and frustrating 

animals on earth. Therefore, we explored them as the

primary representative of the invertebrate fauna of 


As was shown above, the total known, vouchered 

or validly recorded beetle fauna of Montserrat now 

stands at 718 species in 63 families, with at least 81 single-island 

endemics and 53 exotics. An estimate of 827 

species has been proposed for the true total. How does 

this compare to other islands of the West Indies? It is 

difficult to know, because there are so few comprehensive 

treatments, the types of data reported vary greatly, 

and the degree of completeness is so very different. To 

date, 97 families of beetles are known from the West 

Indian Bioregion (Ivie 2007), but no species total is available 

– not even as a wild guess. Island lists of beetles 

published in the last 25 years include those for Cuba, 

Dominica, Grenada and Guana. As expected, giant 

Cuba leads the pack with 2,673 species in 87 families 

(Peck 2005). The other islands all have fewer recorded 

species than Montserrat: Grenada with 507 species of 51 

families (Woodruff et al. 1998), Guana Island, British 

Virgin Islands, with 405 species in 55 families (Valentine 

& Ivie 2005); Dominica with 361 species of 42 families 

(Peck 2006); and Barbados with 239 species of 32 families 

(Bennett and Alam 1985). Thus, Cuba has less than 4

times as many beetle species as Montserrat, and Montserrat 

has more than any other recently reviewed island. 

However, not much can be made of these figures. 

Tiny Guana (300 hectares) is one of the most intensively 

studied islands in the world (Lazel 2005), and is very 

close (ca. 500 meters) to much larger Tortola. Guana 

was joined by land to all of the northern Virgin Islands 

as well as Puerto Rico 18,000 years ago, so of course, it is 

expected to have more species per hectare than an island 

like Montserrat, which has always been isolated by the 

surrounding sea. Peck’s (2005) Cuban book is a summary 

of the existing literature rather than the result of an 

inventory effort, and cannot be expected to be nearly as 

complete as the Montserrat work. So it should not really 

surprise anyone if the total number of beetles on Cuba 

were to be considerably above only 29% of the current 

total. Likewise, the Dominica and Grenada figures reflect 

mostly published records, not an attempt to work 

up the entire fauna in the way Guana or Montserrat 

have been done. Barbados is perhaps at an intermediate 

level of knowledge, with a simplified geography, highly 

modified environment, and considerable work on the 

fauna. Just where Montserrat would settle out if all islands 

were well known is hard to discern, but given 

what we know today, it seems likely that it would be 

found to be on the high side of what would be expected 

based simply on area. 

Another way to look at the expectations of diversity 

is to compare the beetle fauna to the vascular plant 

flora. Plants are in general more completely censused 

than invertebrates, and give another base for comparison. 

A reasonable expectation is that the number of beetle 

species in any given fauna should approximate the 

number of vascular plants. This correlation holds 

broadly, at the global (Chapman 2006 cf. Grimaldi & 

Engel 2006), the continental (BONAP 1994 cf. Marske & 

Ivie 2003), local (Lesica 1985 cf. Ivie unpublished data) 

and insular (Eldredge & Evenhuis 2003, Acevedo- 

Rodríguez 1996 cf. Ivie unpublished data) scales. There 

are an estimated 13,000 vascular plants in the West Indies 

(M. Smith 2005), but no list of the beetles for the 

whole region. Guana’s beetle fauna is 120% of its 339 

species of vascular plants (Proctor 2005). At the other 

end of the scale, Dominica has only 29% as many beetle 

species as its 1,226 vascular plants (Nicolson 1991). In 

the same general range, Barbados’ beetles total 38% of 

her 625 native plants (Gooding et al. 1965) and Cuba’s 

40% of its estimated 6,550 vascular plants. At 76% of 

Montserrat’s 941 verified species of plants, (Hamilton et 

al., this volume), the 718 species of beetles is double the 

ratio reported for Cuba, Dominica and Barbados, but 

considerably below that of Guana. This might suggest 

that Montserrat is simply better sampled than the other 

islands, but the disparity remains unexplained. 

A special effort was made to see which, if any, of 

the species of beetles either recorded or collected from 

Montserrat before the volcanic crisis were not recollected 

after the eruptions. Because of the small number 

of published records, this might seem an easy task. 

However, in far too many cases, this proved very difficult. 

To our best estimate, there are 106 published prevolcanic 

records for Montserrat beetles that seem to be 

valid. Of these, 22 were not recollected. That 21% of the 

beetles previously known from Montserrat were not 

recollected in such an extensive effort seems alarming, 

but because of the different parts of the island where 

sampling efforts were concentrated, and our bias away 

from certain habitats, it may not be of as much concern 

(Table 4.3). 

The most common case of a recorded species not 

recollected is a widespread species from habitats that we 

did not emphasize. Since our efforts were initially confined 

to the habitat of the Montserrat oriole, and later to 

the Centre Hills, missing 13 widespread, often invasive 

species associated with human stored products (Gibbium 

aequinoctiale Boieldieu), human gardens or farms 

[Glyptolennus chalybaeus (Dejean), Proeces depressus 

(Wollaston), Omophoeta albicornis Fabricius], sea beaches 

[Apocellus ustulatus (Erichson), Cafius bistriatus 

(Erichson), Cafius subtilis Cameron, Conotelus conicus 

(Fabricius)], under stones along the lower Belham River 

(Thinobius exasperatus Blackwelder) or dung of domestic 

animals [Neohypnus illucens (Erichson), Oxytelus incisus 

Motschulsky, Philonthus discoideus (Gravenhorst), 

Philonthus longicornis Stephens] is not unexpected. 

Of the 9 species remaining, one case remains 

taxonomically unresolved. The single known specimen 

of Nacaeus foveolus was taken by Hubbard, under bark of 

a Red Cedar (Cedrela odorata L., Meliaceae) on Montserrat 

in 1894. It may well prove to be the same as our 

Nacaeus sp. #1, which differs from the published description 

only in colour and a possible difference in interpretation 

of the word “fovae.” Until a specialist resolves 

this in consultation with the type specimen (NMNH), 

the status of this species is uncertain. 

Four widespread species may indeed have been 

lost on Montserrat: Espeson moratus Schaufuss, Sepedophilus 

interruptus (Erichson), Tetraonyx quadrimaculatus 

(Fabricius) and Neomida lecontei (Bates). The tiny (1.2-1.5 

mm) staphylinid Espeson moratus may simply have been 

overlooked. Apparently never common, Blackwelder 

(1943) reported only 17 specimens from 11 collecting 

events spread among 9 islands. Very little is known 

about this species. Blackwelder (1943) records specimens 

taken flying in Jamaica, in a rotten banana stem in St. 

Lucia, and deep in an unspecified cave, probably in 

Trinidad or Cuba. A specimen taken in a rotten log from 

the type locality, St. Thomas, was available for comparison. 

Another widespread but uncommonly collected 

staphylinid, Sepedophilus interruptus, is a fungivore that 

should have been recollected if it was present, but was 

not found. It was taken on Montserrat by Hubbard in 

1894, but not found by staphylinid specialist Blackwelder 

30 years later. There is not enough known about 

its biology to speculate as to why we did not find it. 

The meloid Tetraonyx quadrimaculatus presents an 

interesting situation. This large (6-12 mm) and showy- 

_______________________________________________________________________________________________________________________ 


62

orange-and-black meloid is widespread, known from 

North Carolina to Trinidad. In reports from the early 

twentieth century, it apparently was common on many 

islands, but in the past 30 years of collecting on some 40 

West Indian islands, we have collected it only on Hispaniola. 

Whether this represents a real, region-wide 

decline or simply bad luck is not known, but the fact 

that the larvae are parasitoids of bees, and that many 

studies show a post-WWII decline in native bees 

throughout the world, is worth noting. If its loss or rarity 

on Montserrat is simply a post-volcano issue, it may 

be due to the effects of ash on the phoretic larvae, which 

ride on the plumose setae of adult bees back to the nest. 

Volcanic ash is well known to accumulate among these 

setae (Marske 2004) and could be involved in this loss. 

Hubbard took a series of 18 specimens of the 

moderately large (6 mm) tenebrionid Neomida lecontei 

(Bates) on Montserrat in 1894. This species feeds on 

shelf fungi on trees and occurs widely from Mexico to 

Brazil, but is recorded only sporadically among the West 

Indies. We collect it regularly in Hispaniola. Our failure 

to collect it on Montserrat post-volcano may well reflect 

extirpation. 

None of the Montserrat populations of these species 

is of global importance, as they are widespread, and 

if they are truly extirpated, could be easily reintroduced. 

The same is not true for the remaining 4 species. 

These 4 species reported from Montserrat, but 

not recollected, represent more critical conservation issues. 

All are known from either several of the Lesser 

Antilles {Metamasius quadrisignatus (Gyllenhaul)], only 

Montserrat and Guadeloupe (Serrotibia n.sp.), only 

Montserrat, Guadeloupe and Dominica (Telephanus nodicornis 

Neverman), or Montserrat only [Cyrtosoma n.sp.]. 

Their loss from Montserrat could represent either a major 

reduction in range or even global extinction. 

The handsome black and red weevil Metamasius 

quadrisignatus is the most widespread and largest (up to 

17 mm including the beak) of these species, known from 

Montserrat, Guadeloupe, Dominica and Martinique 

(Vaurie 1966). Its larva bores in Tillandsia 

(Bromeliaceae), which are among the most likely of all 

plants to accumulate volcanic ash and acidity. It is never 

commonly collected, but would have been expected to 

be taken in canopy fogging samples. We had specimens 

from Dominica available for comparison. 

Leng & Mutchler (1917) recorded the Guadeloupean 

tenebrionid Cyrtosoma lherminieri (Chevrolat) from 

Montserrat, based on 2 Hubbard specimens in the 

NMNH. Marcuzzi (1984) has recorded it from several 

islands from Montserrat to Grenada. We have studied 

Hubbard’s Montserrat specimens, and compared them 

to specimens of both Guadeloupe Cyrtosoma species, C. 

lherminieri and C. picea Laporte & Brullé, determined by 

T. J. Spillman. Our conclusion is that the Montserrat 

specimens represent an as-yet undescribed species, apparently 

endemic to Montserrat. The genus is known to 

be associated with fungi in moist forests, and would be 

expected to occur in the Centre Hills, within the areas

University)

most intensively surveyed by our projects. Yet, we did 

not locate this species. At 13 mm in length, this is the 

second-largest, and only Montserrat single-island endemic, 

species certainly not recollected post-volcanic 

crisis. 

The silvanid Telephanus nodicornis Neverman was 

described from Montserrat and Guadeloupe. It was 

recently recorded from Dominica (Peck 2006). Hubbard 

collected at least 8 specimens on Montserrat in 1894, 

indicating that it was not rare when he visited the island. 

Although no biological information is recorded about 

this species, it belongs to a group of fungivores whose 

adults (and perhaps larvae) live on the surface of dead, 

withered and hanging leaves and branches, probably 

feeding on surface fungi. This expected habitat is among 

the most exhaustively sampled in our survey, yet we did 

not detect it. We have not seen any specimens of this 

species, from any islands. 

Serrotibia n. sp. is a still-undescribed species that 

has been taken at least twice on Montserrat. Again, 

nothing specific is known about its biology, but based on 

other members of the subfamily, it is probably a subcortical 

fungivore. Hubbard’s collections at the NMNH 

were the source of Leng and Mutchler’s (1917) record of 

this species, under an Ecuadorian name which had been 

recorded from Guadeloupe. The species name was then 

synonymised with a Columbian species, and the Guadeloupe 

and Montserrat records went with it. In the Chalumeau 

collection at INRA, we found a single Montser-

at specimen of this genus, representing an apparently 

undescribed native species that is not the same as the 

South American species. It has not been compared with 

specimens from Guadeloupe, so it is unknown whether 

1 or 2 species are involved. This is a beautiful, orange 

and black species, whose loss would be unfortunate. 

An intensive effort should be made to determine 

the fate of these last three species. Because of the general 

survey nature of our work on Montserrat, we did 

not specifically target these species, and they may still 

exist on the island, but if so, they may be very restricted 

and rare. A search of the remaining forest remnant at 

Roache’s is critical, as this is the closest remaining habitat 

to where all 3 were probably last seen. Considering 

the Cyrtosoma and Serrotibia, the very idea that two such 

elegant species might go extinct before even being described, 

is simply sad. 

4.3. An evaluation of the importance of 

Montserrat and the Centre Hills for 

invertebrate diversity 

4.3.1. The importance of Montserrat’s invertebrate 

fauna 

Montserrat is certainly special because it harbours 

endemic species found nowhere else on earth and 

because it represents the major portion of the range of 

many other species. However, this can be said of virtually 

every vegetated West Indian island. Montserrat is, 

after all, only one small component of the Caribbean 

Biodiversity Hotspot, so Montserrat is certainly special, 

but is this kind of “special” really important? 

There are several unique things about Montserrat 

that we believe make it absolutely more important than 

other special places in the region. Unlike endemic species 

that are part of a group occurring as closely related 

species on many Lesser Antillean islands, of which there 

are very large numbers on all the islands, there are also 

groups that are significant evolutionary outliers in the 

Lesser Antilles that occur only on Montserrat, or on 

Montserrat and a few neighbouring islands are important 

at a higher, regional level. Examples from the vertebrates 

are the Montserrat Galliwasp and Mountain 

Chicken discussed at length in other chapters. It is in 

this hosting of endemic groups otherwise absent from 

the region that Montserrat is important from both a conservation 

and scientific perspective. Two very distinct 

sister-species of the genus Thonalmus (Fig. 4.4) are similar 

in importance to the Montserrat Galliwasp. They are 

single-island endemics that represent the only Lesser 

Antillean members of a small, West-Indian-endemic 

lineage, otherwise present only in the Greater Antilles 

and Bahamas. This group is so colourful, abundant and 

obvious that it seems very unlikely that it has been 

missed on other Lesser Antillean islands. Further, 

Thonalmus have been on the island long enough to produce 

other single-island endemics that are mimetic associates, 

for instance Strangalia benitiespinali Chalumeau. 

Fig. 4.6. Eohomopterus sp. (Photo: M. Ivie, Montana 

State University) 

Another example of the importance of Montserrat 

is the radiation of the anobiid Trichodesma (Fig. 4.5), 

with five undescribed species on the island. These are 

the largest, or among the largest, species of the family in 

the West Indies, and are by far the most strikingly coloured. 

Guadeloupe has had its Anobiidae reviewed 

twice, and has never had a member of this genus reported. 

No other Lesser Antillean island is known to 

harbour Trichodesma. The closest island known to have 

Trichodesma is in the Greater Antillean Virgin Islands, 

and those species are very different from the Montserratian 

species. There are many more examples of this kind 

of “importance” scattered through this report, but again, 

a majority of the larger islands in the Antilles can make 

similar claims to importance, even if based on different 

details. 

So, Montserrat is special and important, but is it 

an island of such high biodiversity as to be on a unique 

scale? It is virtually impossible to establish this as fact at 

any credible level, because virtually any comparison 

with other islands is not valid due to a number of reasons. 

Differences in effort, emphasis and reporting 

make it very difficult to compare any two samples, if 

and when they exist. Even within Montserrat, different 

groups of collectors find different things. Comparing 

the various collections of Montserrat rove beetles 

(Staphylindae; Appendix 2, Table E), butterflies and 

flower flies (Syrphidae) shows this very clearly. 

There are many examples of groups with new 

and apparently endemic species on Montserrat scattered 

though this report that represent apparent outliers, but 

are members of groups so poorly studied that the reality 

of the gap cannot be evaluated. The very odd undescribed 

weevil Prionarthrus n. sp. belongs to a group 

known otherwise from only a single described species 

from Brazil. The unique Eohomopterus (Fig. 4.6) from 

Katy Hill is one of only 2 extant species of the subfamily 

_______________________________________________________________________________________________________________________

Paussinae known from the West Indies, and with its 

sister-species from Guadeloupe, are related to fossils in 

Dominican Amber. Both of these Montserrat endemics 

are known only from single specimens, and appear to be 

so rare that only extensive inventory efforts would find 

them. Are their lineages absent from other islands, or 

simply undetected? Most of the real biodiversity of islands 

in the Lesser Antilles remains virtually unknown, 

so that even though Montserrat has so many more 

known species per hectare than other islands in the region, 

it would be foolhardy to assert that this is evidence 

of Montserrat’s special stature. 

For the beetles the exception in the Lesser Antilles 

is Guadeloupe, which is reasonably well-known. 

Guadeloupe is, however, not an island but an archipelago 

of many islands that together have an area of 1,706 

km². Many, if not most, of the records are for the Department, 

not an individual island within it, making use 

of the data an unfair comparison. No Order-level checklist 

is available for the beetles of Guadeloupe, much less 

for its individual islands, so only a few groups can be 

examined. However, examples such as the Anobiidae 

mentioned above, where well-collected and twicereviewed 

Guadeloupe has 25 known species compared 

to Montserrat’s 32, gives one pause. On the face of it, 

comparison of Montserrat to Guadeloupe gives enough 

support to the idea of Montserrat’s uniqueness that we 

are still tempted to be amazed. 

One possibility of an independent data-set with 

which to evaluate Montserrat’s unique status may be 

Dominica. In the mid-1960s the Archbold-Breden- 

Smithsonian Survey of Dominica (ABS) sent the most 

richly equipped and well-supported expeditions ever 

seen in the region to that island. Together, the participants 

formed the largest pool of expertise ever to collect 

on any island east and south of Puerto Rico (Peck 2006). 

Their material was assembled at the Smithsonian, and 

reviews of many groups were published, giving us the 

best modern reviews of any Lesser Antillean island. 

Montserrat, on the other hand, has had far less expertise 

devoted to it. Of the many collectors that participated in 

our work, only the Ivies were fully trained collectors 

before arriving on the island. The others, productive 

and hard-working as they were, received their advanced 

training on-island during their stay(s). It seems that 

under these conditions, it is reasonable to expect the 

relative efforts on the 2 islands should be somewhat 

comparable, or for Dominica to be a bit better collected 

than Montserrat. 

Dominica is more than 7 times the area of Montserrat, 

and nearly 1.5 times as high. During our work, 

the vegetated extent of Montserrat was reduced to half 

of its area and removed the highest areas from the habitable 

area for insects, making Dominica nearly 15 times 

as large and twice as high as functional Montserrat. 

Thus, if Montserrat were just a normal “special and important” 

Lesser Antillean island, larger, wetter and 

higher Dominica would be expected to have many more 

species than Montserrat – at least twice the number under 

Darlington’s Rule of Thumb (MacArthur & Wilson 

1967). 

Yet, for the taxon best sampled by our group, 

Montserrat has 718 beetle species of 63 families, while 40 

years after the ABS, 361 species of 42 families are now 

reported from Dominica (Peck 2006), even though 3 of 

the ABS participants and 5 other contributors were professional 

research coleopterists (loc. cit.). Perhaps this is 

an unfair comparison, as we have worked up all the 

Montserrat beetles, but this has not been done for the 

Dominica samples. However, even for subgroups of 

beetles that have been fully worked, the totals do not tell 

the expected story. For instance, the 26 Scarabaeoidea 

we record from Montserrat is significantly below the 42 

reported from Dominica, but still more (62%) than the 

less-than-half expected. Another well-worked family is 

the Cerambycidae, where Montserrat’s 33 species, at 

79%, is again well above the one/half-level of Dominica’s 

42 species. For other fully-worked groups the story is 

also not so different as expected (numbers indicate Dominica 

and Montserrat respectively): Leiodidae (3,3), 

Buprestidae (7,7), Scydmaenidae (2,3), Carabidae 40,29). 

Moving to another Order, we did not actively 

seek out aculeate wasps, which hymenopterist Howard 

Evans targeted on Dominica, yet for the 6 families whose 

species have been identified from both projects, the expert 

on Dominica was equalled by the incidental on 

Montserrat at 29 and 29 species. There were 4 dipterists 

on the ABS, while we made no special effort to obtain 

flies on Montserrat, yet Dominica has only 23 reported 

flower flies, compared to 22 for Montserrat. The 46 

Montserrat species of Dolichopodidae is about what is 

expected compared with Dominica’s 113, until you consider 

that Harold Robinson is a dolichopodid specialist 

who personally conducted very directed collecting on 

Dominica, and we only took what fell incidentally into 

our traps. Further, Dolichopodidae are most diverse in 

wet habitats, of which Dominica has far, far more than 


Our studies on the invertebrate fauna of Montserrat 

point towards the true number of endemics being in 

the hundreds of species. There are 81 probable singleisland 

endemics in just the Coleoptera (Section 2), which 

comprises only one-third of the described Insecta. If 

local endemics are added in, i.e. those occurring on only 

a few neighbouring islands, another 54 species are 

added. Yet another 33 Leeward Island or Northeastern 

Antilles Endemics are represented. Thus, Montserrat is 

home to some 167 beetle species that occur either only 

on Montserrat or on it and a few neighbouring islands. 

Undoubtedly these numbers are all underestimates, because 

over 1/3 of the species of beetles are too poorly 

known to even rank their distribution status. Thus, that 

167 species of known conservation concern is nearly 40% 

of the pool of 445 that have an assigned distribution 

ranking. Keep in mind that the easiest species to identify 

are the widespread ones, so the proportion of endemics 

among the 270+ species still unranked may be higher 

than in the first 500, indicating that there are probably 

_______________________________________________________________________________________________________________________ 

65 


more than 100 species of beetles of conservation concern 

to be added to the total above. 

Moving beyond the beetles, there is no reason to 

expect that the Coleoptera are any more likely to evolve 

endemics than the rest of the Insecta. We know of 32 

more non-beetle single-island endemics, and 3 among 

the non-insect invertebrates, with nearly again as many 

local island, Leeward Island and Northeastern Antillean 

endemics. This means that the density of endemics and 

species of conservation interest is already so high that it 

should be measured in endemic species per hectares 

rather than endemic species per square kilometre on 105 

km² Montserrat. This density of endemism is a far better 

indicator of the importance of Montserrat than the number 

of endemics. With such a density of globally important 

species, a hectare of development on Montserrat 

may potentially have a far greater impact on global biodiversity 

than on Cuba, or Brazil, or Madagascar. 

Thus, we have to seriously consider the hypothesis 

that Montserrat is truly more diverse than expected, 

particularly when compared to Dominica and other 

Lesser Antillean islands. Again, we caution that these 

bits of information are highly suspect due to differences 

in collecting effort, expertise, technique and reporting, 

but they at least are strong enough to raise the issue of 

Montserrat’s uniqueness to a level that requires consideration 

of the possibility that it is more than just another 

“special and important” West Indian island. Thus, at the 

current state of knowledge, biodiversity managers can 

choose to consider these indications of uniqueness to be 

artefacts, or indications of reality. The consequences of 

being wrong, however, are very different for these two 

choices. There is no negative effect of protecting this 

“special and important” island, even if it is not unique, 

but to fail to do so and then discover that it was a globally 

unique place would be unforgivable. Thus, managers 

responsible for biodiversity would do well to proceed 

with caution before considering Montserrat an average 

“special and important” island, and, until data 

become available to show otherwise, proceed under the 

assumption that it is also a “uniquely biodiverse island.” 

4.3.2. The importance of the Centre Hills for 

Montserrat’s invertebrates 

It is well known that the only high-quality forest 

habitat left on Montserrat at this time is in the Centre 

Hills. What is less well-known is that this area is also 

the one most likely to harbour endemic species that 

evolved on the island (versus those that were once widespread 

and are now extinct elsewhere, similar to the 

Mountain Chicken). It is clear from the number of sibling 

species on Montserrat and Guadeloupe that a pattern 

of on-island evolution has indeed happened repeatedly. 

Darlington (1943) correctly pointed out that the 

oldest elements of a fauna, and usually the most specialized, 

will be expected on the tops of the highest peaks of 

islands. However, in this case “highest” assumes the 

mountain has been habitable for a long time. On Montserrat, 

a volcanic eruption in the early seventeenth century 

laid the southern mountain top bare, much as in the 

current volcanic crisis, forcing any forest and associated 

animal communities to later recolonise the south, far too 

short a time to produce the number of endemic species 

we see. The Centre Hills, on the other hand, has highelevation 

montane forest that is old in evolutionary time. 

If specialized high-elevation species were to evolve on 

Montserrat, it is in the Centre Hills that they would be 

found. The great increase in the number of known endemic 

species we have documented on Montserrat is 

attributable in large part to increased sampling intensity, 

but is also the result of the concentrating on this evolutionarily 

old and biodiversity-rich set of hills. 

The exact number of the known species of Montserrat 

that occur in the Centre Hills is still unknown. 

However, because our collecting effort was concentrated 

on the Centre Hills, we tentatively estimate that some 

90% of Montserrat’s invertebrate species we detected 

occur there. All but a handful of the known Island Endemics 

occur in the Centre Hills, and a majority of them 

are only recorded from that area. Those species not yet 

known from the Centre Hills are mostly widespread 

inhabitants of beaches, dry coastal scrub, or invasive 

species associated with human habitations (stored food 

or gardens). None of these species are of conservation 

importance. 

In summary, the Centre Hills clearly supports 

that vast majority of Montserrat’s invertebrate fauna, 

and given the dominance of this group in overall biodiversity 

it therefore supports the majority of the total 

biodiversity of Montserrat. If we were to select a species 

to represent Montserrat’s modern fauna, we would 

choose a globally rare, 3mm-long beetle first discovered 

in 2002, known only from the Centre Hills from a single 

individual, and which is either undescribed or cannot be 

named with certainty. Since this theoretical representative 

species is a stand-in for literally hundreds of others, 

and given that the Centre Hills is such a small area, they 

are therefore perhaps one of the very most critical areas 

on earth in terms of the density of unique biodiversity 

per hectare. This is the message in the invertebrate signal 

on Montserrat that most needs to be addressed.

Box 2. Challenges of conducting the invertebrate inventory 

There are a wide range of large challenges to conducting an invertebrate inventory. Lack of collection data is 

one problem (more on this later), but the taxonomic impediment is the major factor. The fact is that any knowledgeable 

amateur naturalist with a single book and binoculars can identify every species of resident breeding bird on the island 

without ever touching one. The same is true for the amphibians and reptiles. A few hours of training are necessary to 

be sure of the bat and rat species, and some of them have to actually be held in the hands in order to identify them, but 

a pair of gloves and a hand lens are the extent of the additional equipment needed. There are significant numbers of 

people who could identify every resident breeding species of 4 Classes of Montserratian terrestrial vertebrates 

(Amphibia, Reptilia, Aves, Mammalia). However, no single person alive can authoritatively identify all of the species 

of any of the major Classes of Invertebrates on Montserrat. Even identifying the major Orders of arachnids and insects 

is out of the question. There are just too many of them, they are too small, and the literature that does exist is huge, 

scattered, and of a widely varying quality, with an often convoluted and confusing nomenclature. 

The simple numbers of species of invertebrates is the first reason for the imbalance. The 44 native and 9 

introduced terrestrial tetrapods on Montserrat contrast with over 718 known beetle species, (plus the 109 or more 

expected to still be discovered), with probably 2-5 times that number combined in flies, moths, bugs, mites, spiders and 

wasps/ants/bees. The number of nematodes (undoubtedly huge) is totally up for grabs, but there is no one who could 

identify them to a level that would allow us to count them anyway. Thus, the simple number of invertebrate species to 

be determined overwhelms any single naturalist. 


Size is the next factor contributing to the problem. Virtually everyone can spot and identify the Soldier Crab or 

the White Land Crab, but these are the

Cotton Ginner (Sphaerodactylus fantasticus

largest 2% of beetle species on the island. 

Few people do not find it easier to identify 

an eagle species than a warbler, and size is 

an important part of that equation. Think 

about that when considering that the 

average beetle species on Montserrat is 4.55

Invertebrates, as an aggregate of 

individuals, average even smaller. Fig. 4.8 

shows the size distribution of all arthropods 

taken from a 10 meter by 10 meter section 

of forest canopy in the Centre Hills (from

A month earlier, one from Hope Ghaut 

taken 16 May 2002, included a stunning 

18,916 individual arthropods. Yet, 12,000 

of those were in the 1 mm range. It is no 

wonder that although the number of 

individuals in this 100 square meters is 

huge (nearly 190 individuals per square 

meter), they are seldom noticed by the 

casual observer. 

Tiny species can live in tiny places, and so it 

takes huge efforts by very knowledgeable 

specialists in hundreds of very specialized 

habitats, using equally specialized 

equipment, to find more than 20% of the 

invertebrate species in a given area.

variation in the numbers of invertebrate 

species than it does in the generally longerlived 

tetrapods, and many visits and much

work is needed to find even 50% of the 

species in a given area. True or perceived 

rarity is the result, making it a long-term 

numbers game to encounter the tiny, the 

specialized, the seasonal and the truly 

rare. Of the 718 species of beetles now 

known from Montserrat, more than half 

are known from 5 or fewer specimens, 149 

from only one, another 40 from only 2 

(Fig. 4.9). 

Keep in mind that these numbers were 

collected after obtaining and searching 

through approximately 1 million 

specimens of arthropods. The effort 

expended to reach this point has been 

huge. A reasonably competent amateur 

can find and identify half the species of 

tetrapods on Montserrat in the course of a 

week of concentrated field work, but 

obviously that is not at all true for 

invertebrates. Fig. 4.10 shows that it took 

98 years to reach the 50% point in 

discovery of beetles on Montserrat. This 

is, in large part, because most of the visits 

to Montserrat by invertebrate zoologists 

were in the range of a few days, with a 

few spending a week or two and very few 

staying for a month or more. Short visits 

mean that one is most likely to find the 

same relatively moderate-sized, abundant, 

and often invasive, anthropophilus and 

pestiferous species over and over again, 

without ever really getting to the core of 

the fauna. This is why the vast majority of records come from only a handful of investigators. This can be seen very 

graphically in the pattern of discovery of beetles on Montserrat (Fig. 4.10). There are 5 collectors or groups whose 

efforts added the vast majority of beetle species over the period starting in 1894 and ending 2005: Hubbard (1894), 

Blackwelder (1936), Cooter (1975), Chalumeau (1982-1984) and Ivie et al. (2000-2005). 

Thus, it takes a huge amount of time and effort to find the large number of small species of invertebrates. 

Identifying them is another major problem. Compounding problems of numbers and size is that fact that there are 

simply too few invertebrate systematists to do the work, and in general, funding for them is very low. Even after 

specimens are collected, often there is no one to identify them. Table 4.4 lists the 62 families of beetles known from 

Montserrat, arranged by numbers of species found. Note that for 2 of the 5 most speciose families, no living specialists 

exist who can identify the West Indian members of the family, and for only 3 of the 10 largest are there specialists who 

can deal effectively with the entire fauna. There are no specialists with taxonomic expertise available for 39 of the 62 

families of beetles known from Montserrat. In addition, the availability of coleopterists is far better than for specialists 

who work on mites, spiders, nematodes, flies or parasitic wasps. 

Lack of literature resources is the third taxonomic impediment. Even where no specialist is available, the 

existence of good papers would allow the identification of much collected material by non-specialists. However, while 

single books or references allow authoritative identification of any bird, amphibian, reptile or mammal on Montserrat, 

the same is not true for any Class of arthropod. In fact, only for a few small Orders, namely the Dermaptera (earwigs), 

Odonata (dragonflies and damselflies) and Isoptera (termites), are such works available, and they require the expertise 

of a specialist in order to use them. Even for the lower taxonomic unit of Family the situation does not become much 

easier, as very few comprehensive works are available, and most of them are only usable by a specialist. Among the 

entire Montserrat invertebrate fauna, only the butterflies, a mere 43 species, have an identification guide usable by the 

lay naturalist. 

The quality of the literature that is available is another factor. Unlike a bird field guide, the literature that does 

exist is very difficult to use. In assembling the list of Coleoptera below, references were consulted that were written in

English, Latin, French, German, Spanish, Portuguese and Russian. Some were over 200 years old, and written at a time 

when the standards for description of a species were very different from today, yet for many groups, nothing more 

recent has been published. Often the publication has only a description of a single species, and lists nothing 

comprehensive for the group that would allow one to understand whether the specimen being examined is the same as, 

or different from, a species reported only from Guadeloupe, or Puerto Rico, or Grenada. These publications include 

illustrations for fewer than 5% of the Montserrat beetle species, and many of these are of limited use. Most frustrating 

is that after assembling all these papers, reading and translating all these descriptions, consulting with a whole raft of

specialists, and comparing the specimens with the largest collection of West Indian beetle specimens in existence (Fig. 

4.11), only a relative few species can be confidently associated with an existing scientific species name. A few more can 

with certainty be determined as undescribed, but a huge portion remains in limbo. 

Montserrat has been visited by entomologists and invertebrate zoologists since at least 1894. However, no 2 

collectors ever find exactly the same things. Because of the incomplete and constantly changing level of work on the 

taxonomy of invertebrates, the correct names change with further information. It sometimes takes a massive amount of 

work in the library and museum in order to know whether the species you have just collected is the same species as 

that recorded from Montserrat 100 years ago, and again recorded under a different name 50 years ago. The voucher 

specimens that are the key to this system may be in London, UK, for one record, and in Washington, DC, USA, for the 

second, while we are working in Bozeman, MT, USA, so actual comparison is not practical in the short time available. 

Dealing only with literature records is far more difficult than if a voucher specimen is at hand. A few records 

are clear mistakes, and can be rejected. Other records are suspected, with a high degree of probability, to be 

misidentifications, and can be placed with confidence under species we collected. Far too many records can neither be 

associated with species we collected, or confidently excluded as something we did not collect. 

Montserrat’s plight in this regard is not unique; in fact it is the global norm. As an example of how these factors 

play out in the real world, we will take the example of the Montserrat Staphylinidae, one of the two most diverse 

families of beetles (Table 4.4). Unlike

West Indian beetles, a large portion of the 

S t a p h y l i n d a e ( e x c e p t i n g t h e 

Aleochorinae, Pselaphinae, and 

Scaphidiinae) were revised as a whole in 

modern times, and there are descriptions 

and keys to the species for the entire West 

Indian fauna known at that time 

(Blackwelder 1943). As such, the 

Staphylinidae is a best-case study, with 

most other families of beetles scattered on 

a scale of less optimal conditions. The 

reviser, Richard E. Blackwelder, assisted 

by his wife, Ruth, spent 2 weeks 

collecting on Montserrat, from 13-27 July 

1936. Blackwelder reported that they 

collected 15 species of the group to be 

revised. Interestingly, and as a harbinger 

of things to come, in the text we find 16 

species reported as collected by the 

B l a c k w e l d e r s o n M o n t s e r r a t . 

Blackwelder worked at the Smithsonian 

in Washington, DC, where he had access 

to the other large collection of Montserrat beetles of his day – that of Henry Guernsey Hubbard, who spent parts of 

February, March and April of 1894 on the island. Although Blackwelder was a specialist in the Staphylinidae, was on 

the island specifically to collect Staphylinidae, and was assisted by his wife, the generalist collector Hubbard bested 

them, and collected 18 species of the groups of Staphylinidae under revision. Most surprisingly, the two collections 

had only 2 species in common. So, Blackwelder had a total of 32 species recorded from Montserrat, a 78% increase by 

the second expedition over the first. 

Only a single additional species was recorded from Montserrat between 1943 and the review of the fauna by 

Stevens and Waldmann (2001), but some already recorded species were treated by various workers, moved from the 

names used by Blackwelder to other nomenclatural combinations and synonyms. Stevens and Waldmann recorded 34 

species of Staphylinidae from Montserrat - all dating to the Blackwelder (1943) revision. It turns out that the increase 

was due to double reporting of 2 species which had been moved to other genera subsequent to Blackwelder’s work, 

with Stevens and Waldmann then using both the new combination and the one Blackwelder used. So, the real number 

of recorded species was 33 (Blackwelder’s 32 plus one missed by Stevens and Waldmann), not the reported 34 (Table 

4.5). 

Our work on Montserrat began in 2000, and has involved several person-years of collecting, and trap-years of 

passive collecting. This represents many times the collecting effort by Hubbard and the Blackwelders, and, not 

surprisingly, we have again doubled the number of species of Staphylindae (excepting the Aleochorinae, Pselaphinae,

and Scaphidiinae) to 77 or more, up to 80. Although we can say that we have collected 67 species of this group on 

Montserrat, we cannot say for certain how many of the previously reported 33 species we have collected, nor how 

many of our species are not among the 33 that were included in the 1943 treatment of the whole West Indian fauna, 

because the literature is simply inadequate. The 1943 paper is 658 pages long, includes keys to 468 species, but includes 

only 8 illustrations. Given the nature of a key, each of our specimens is likely to key out to some species, but if that 

species is known from Puerto Rico, how can we know whether it is the same species as the one we have, or something 

unique and different? 

This discussion illustrates 3 points: the fauna of Montserrat is poorly documented, allowing the near doubling of 

the known species between the first visit by a beetle specialist and the second, and again by our group; that a simple 

listing by a non-specialist of all the names ever used for a fauna will be prone to a great deal of error; and that summary 

works (including this one) must be checked against the original literature and voucher specimens before being used for 

significant management decisions.

Box 3. A history of invertebrate collection in Montserrat 

Until recently, invertebrate collections from Montserrat were themselves small, scattered and even today they 

are incomplete. No comprehensive history documenting the discovery process for invertebrate zoology on Montserrat 

exists, but by carefully noting the label data on specimens we have seen, and those recorded in the primary literature, 

some of the more important visits can be reconstructed. This listing is incomplete, and biased towards the collectors of 

groups we have studied, but it gives some picture of the situation. Most of the information concerns entomologists, 

with a few references to other disciplines extracted from Stevens and Waldmann’s (2001) review of the fauna or the odd 

record. The impact of these workers on our knowledge of the beetle fauna is particularly noted. No attempt has been 

made to include unicellular groups, nor parasites of medical or veterinary importance, as that literature is of an entirely 

different character and beyond our expertise. 

The first person known to have collected invertebrates from Montserrat for scientific study is assumed to be Sir 

Rawson William Rawson (1812-1899), who sent 5 species of terrestrial snails from Montserrat to Thomas Bland for 

determination prior to 1875. Sir Rawson was Governor of Barbados and Governor-in-Chief of the Windward Islands 

(1868-1875), which did not include Montserrat (Anon. 1900). Exactly if and when he personally visited Montserrat is 

uncertain, but from this material, Bland (1875) described Amphibulimus rawsonis Bland, the first invertebrate we know 

of to be named from the island. 

The first entomologists to collect on Montserrat were apparently the head of the United States Department of 

Agriculture’s Division of Entomology, Charles Valentine Riley (1834-1895) and his assistant Henry Guernsey Hubbard 

(1850-1899). Riley’s work on biological control of citrus pests seems to be the basis for the earliest reports of specific 

insects from the island. Montserrat had begun exporting lime juice in the 1850’s and production peaked in 1884. 

Shortly after, an outbreak of scale insects attacked the lime trees, affecting the island’s lime juice industry. Riley was 

the most famous economic entomologist of his day, and had directed the successful control of the cottony cushion scale 

on California citrus using a ladybird beetle. Probably as a result of this fame, Riley received a letter dated 10 May 1890 

from the Montserrat Company in Birmingham, England, asking him to send some of the ladybirds to control a scale 

said to be related to the cottony cushion scale. Because of the very specific nature of the food habits of the ladybird in 

question, Riley requested that a sample of the scales be sent to him by the Company’s attorney in Montserrat, Mr. H. de 

C. Hamilton. When the specimens arrived, those from lime included the recently described snowy citrus scale [Unaspis 

citri (Comstock, 1883), then called Chionaspis citri Comstock] and the purple scale [Mytilaspis citricola (Packard)]. 

However, in the same package was indeed a new species of the same genus as the cottony cushion scale, albeit from 

Chrysophyllum leaves, not lime. Riley and H. C. Howard described this new cottony cushion scale as Icerya 

montserratensis Riley & Howard. This trio of records may be the earliest insect report from Montserrat (Riley & Howard 

1890). Whether the ladybird beetle that was the original reason for the correspondence was ever sent to Montserrat 

seems to remain unreported, and we did not find that species on the island, nor any records of it from the intervening 

years. Correspondence between Riley and agriculturalists in the region continued, and in 1893 Riley published a note 

listing scale insects collected by Mr. C. L. Barber (cited as C. A. Barber in some sources), Superintendent of Agriculture 

in the Leeward Islands, including 6 species from Montserrat (Riley 1893). 

By 1894 the scale problems on lime trees were becoming very serious (Innanen 1998). Following up on the initial 

relationships, Riley and Hubbard visited Montserrat in February, March and April of 1894, officially looking for 

parasitoids of citrus pests (Smith and Smith 1996). Interestingly, a lack of official authorization for this trip led to 

Riley’s resignation from his post, ending the career of one of the most celebrated entomologists of all time (Smith and 

Smith 1996). Riley and Hubbard material is deposited at the Smithsonian’s National Museum of Natural History, 

Washington (NMNH). 

Only a few Montserrat specimens with Riley’s collection labels survive, but Hubbard was prodigious in his 

efforts, and hundreds, if not thousands, of specimens bear his collecting label. Even today, this is the second largest 

collection of Montserrat insect specimens in existence. Hubbard did not describe any of the species himself, but his 

material has formed the basis for the majority of published records of Montserratian beetles to date. He concentrated 

mainly on beetles, and records of at least 57 of the 107 species of beetles previously recorded in the literature from 

Montserrat date to his material (Table 4.6). 

The first 27 beetle species records in the literature for Montserrat (Hopkins 1915, Leng & Mutchler 1917) seem to 

be totally derived from Hubbard’s material, but his material has continued to be studied, so that another 32 (or 33, 

origin of one is uncertain) first reports of Montserrat beetles have appeared in 19 papers by 16 different authors over 

the years, one as recently as 2006 (Table 4.6). It is likely, even certain, that more, perhaps many more, first collections 

remain undiscovered, scattered through the tens of thousands of drawers of beetles at the Smithsonian. For practical 

reasons, it would be impossible to effectively search them all to reassemble exactly everything Hubbard found, but his 

records will continue to appear in the literature as groups are revised. Hubbard’s contribution has been honoured with 

four Montserrat insects that bear the species epithet hubbardi (Stevens and Waldmann 2001). Although this was 

Hubbard’s only trip to Montserrat, the literature sometimes incorrectly reported a specimen from 1923 (e.g. Vaurie 

1966). In fact, the label on these specimens reads “Mar. 19-23” and lacks a year, leading to the misinterpretation.

Several other entomologists are known to have followed Riley and Hubbard after the turn of the century, most 

for only a short period of time and collecting only a few specimens, or specializing on a particular narrow group. The 

English entomologist Harold Maxwell Lefroy (1877-1925) collected on Montserrat in August, 1901, before achieving 

fame as the entomologist to the Government of India (Rehn 1905), and Henry Arthur Ballou (1872-1937), the 

Entomologist of the Imperial Department of Agriculture based in Barbados, collected on Montserrat in January, 1904 

(Rehn 1905, Rehn and Hebard 1927) around the time (1905) another scale, the green shield scale (Coccus viridus Green) 

was recorded attacking young lime trees (Ballou 1912, Innanen 1998). The specimens of Lefroy and Ballou are scattered 

among the collections of specialists. Another USDA entomologist, the Lepidopterist August Busck (1870-1944) has 

been reported to have been on the island in June 1905 (Thompson 1981, specimens in NMNH). However, these 

specimens were actually collected at Montserrat, Trinidad (see label data cited in Stone & Knight 1957). 

In 1906, the Curator of the Montserrat Botanic Station, W. Robson, sent 2 species to the Imperial Commissioner 

of Agriculture in Bridgetown, which formed the basis of a published record (Robson 1906). Rounding out the first 

decade of the twentieth century, Thompson (1981) reports fly specimens in the NMNH from an unnamed collector on 

the island in March of 1910. 

Amos Peaslee Brown (1864-1917), Professor of Geology and Mineralogy at the University of Pennsylvania, was, 

among other things, an avid malacologist interested in both paleontology and land snails (Stone 1918). The fact that he 

collected snails on Montserrat in 1913 is documented only through the existence of his specimens in the Academy of 

Natural Sciences, Philadelphia. He is known to have visited Antigua in July and August of that year, and he published 

a paper on the geology of that island (Brown 1913). Exactly what his purpose was on Montserrat, be it pursuit of his 

interest in malacology, paleontology, geology, or some other reason is unknown.

From 1910 to 1922, we find no records of visits to Montserrat that yielded insect specimens. Stuart T. Danforth 

(1900-1938) of the University of Puerto Rico is best known as an ornithologist, but was also an accomplished 

entomologist. He visited Montserrat on 4 short visits in July 1922, July 1931, June 1935, and August 1935. Finally, in 

February 1937, he made a more extended visit. He collected insect and avian specimens on the island, and performed 

several bird stomach dissections that yielded insect and snail records (Danforth 1939, Thompson 1981). His insect 

collection is now at the Museum of Comparative Zoology, Harvard University. 

The Montserrat resident, historian and naturalist T. W. Savage-English collected the first Onychophorans known 

from Montserrat in April 1924. His specimens are in the NMNH and BMNH (Clark 1929, Read 1988). Brooks (1998) 

reports a bee in the NMNH collected on Montserrat on 13 September 1925, but the collector is not reported, and this 

date does not match any of the known collectors. In July, 1929, William A. Hoffman of the School of Tropical Medicine 

in San Juan, and his assistant José Oliver-Gonzáles (later of the University of Puerto Rico) bred several species of 

mosquitoes from a crab hole which found their way to Belkin and Heinemann (1975) (see below). These specimens 

became the source of the original mosquito records for the island (Belkin and Heinemann 1975). No report of other 

material Hoffman and Oliver-Gonzáles may have collected has been found. 

Richard Eliot Blackwelder (1909-2001), assisted by his wife Ruth MacCoy Blackwelder (1910-1989), spent 2 

weeks in July, 1936 collecting on Montserrat, under a W. R. Bacon Fellowship (1935-1938) at the Smithsonian 

Institution. He published a detailed list of his localities and collecting efforts (Blackwelder 1943). Although the 

Blackwelders were concentrating on Staphylinidae, they picked up numerous other groups as well, most of which can 

be found in the NMNH. Their collecting has been the basis for the second largest group of published beetle records for 

the island (Table 4). Later in his career, he produced the most recently published checklist and bibliography of 

Neotropical beetle species (Blackwelder 1944-57), and still later became one of the foremost scholars of J. R. R. Tolkien! 

His efforts on Montserrat are described in more detail above. 

The famous Homopterist Ronald Gordon Fennah (1910-1987) spent much of his career in the British West Indies, 

first as Lecturer in Zoology (1935), then the Citrus Entomologist for the Windward and Leeward Islands (1937-1942), 

and finally Officer-in-Charge for the Food-Crop Investigation for the Windward and Leeward Islands (1942-1948), all 

three at the Imperial College of Agriculture in Trinidad (now University of West Indies). His visits to Montserrat 

ended when he became Entomologist of the Department of Agriculture for Trinidad (1948). Originally from the Welsh 

Marches, he left Trinidad after 22 years in the West Indies (1958), and joined the Commonwealth Institute of 

Entomology in London, where he finished his career as Director. His 1937 hire required him to investigate a 

mysterious die-off of lime trees in Montserrat (Lapointe 2000). He visited the island several times, starting in January 

1938 (and at least in September, 1939 and May, 1941). He reported numerous Fulguroidea from the island in the 17 

papers he published on the Homoptera of the West Indies. He described 10 of the 12 species of Fulguroidea known 

from the island today, including all 6 of the single-island endemics. In addition, Fennah recorded several economically 

important species in his agricultural papers, and provided specimens of many groups to others (Thompson 1981). 

Type material from his West Indian period is deposited in the NMNH, and his later material is mostly deposited in The 

Natural History Museum, London (Wilson 1988). 

Botanist George R. Proctor (1920- ) collected a specimen of dung beetle (Matthews 1966), a ground beetle (G. Ball 

pers. com.), and perhaps other specimens, in February, 1959. His material is deposited at the Science Museum, Institute 

of Jamaica, Kingston. The Smithsonian-Bredin Caribbean Expedition, on the Research Vessel Freelance, apparently 

made a port call at Montserrat in April, 1959, yielding specimens of Crustacea collected by Thomas Elliot Bowman III 

(1918-1995) on the beach at Fox’s Bay. Several records of marine species undoubtedly date to this voyage. Other 

specimens of Crustacea at the NMNH date to an M. S. Carson, collected in December, 1963. 

Reference to a single Montserrat lygaeid in the Leiden Museum, Netherlands (Slater & Baranowski 2005), 

collected 15 July 1965 by a Mrs. E. Geijskes, indicates a potentially unstudied collection at that museum. Ester “Ettie” 

Sollewijn Gelpke (1909-1994) was the wife of Dutch Odonatologist Dirk Cornelis Geijskes (1907-1985), famous for his 

work in Suriname. To our knowledge, that single specimen is the only indication of a visit by one or both of them to 


In October, 1966, a team visited Montserrat led by the well-known Yale University medical entomologist 

Thomas Henry Gardiner Aitken (1912- ), who was then at the Trinidad Regional Virus Laboratory (TRVL). Aitken, 

along with TRVL staffers Ambrose Guerra and Raymond Martinez, surveyed Montserrat’s mosquitoes for the 

Mosquitoes of Middle America Project (Belkin and Heinemann 1975, 1976). They visited 134 localities (Belkin and 

Heinemann 1976), covering the island better than any other invertebrate collectors. Their thoroughness is the reason the 

mosquitoes, along with the butterflies, are the best known group of invertebrates on the island. After a few stops along 

the way, the collections from this project are now at the NMNH.

Dutch zoologist Pieter Wagenaar Hummelinck (1907-2003) collected for a single day, 20 July, 1967 (not August 

as reported in Stevens & Waldmann 2001), as part of an area-wide survey of various animal groups (Wagenaar 

Hummelinck 1981). His insect collections are deposited mostly in the Leiden Museum. 

The Charles W. O’Brien collection contains weevil specimens collected in May 1968 and October 1971 by Peter 

Call Drummond (1937 - ), an isopod specialist from Santa Fe Community College, Florida. These specimens were 

submitted to O’Brien for identification by M. Sommeijer (presumably the Dutch entomologist Marinus J. Sommeijer, 

who worked for the UN Food and Agriculture Organization in Trinidad from 1971-1974) (C. W. O’Brien, in lit.). 

Montserrat specimens collected in November 1967 and July-August 1971 by Hawaiian biocontrol specialist Noel 

Louis Hilmer Krauss (1910-1996) are in the NMNH (Brooks 1998, Thompson 1981, Kung and Brown 2006). Fred D. 

Bennett, another biological control specialist based at the Commonwealth Institute of Biological Control in Trinidad, 

collected on Montserrat in February 1964, November 1973 and May 1974 yielding specimens of biological control 

agents (Gordon 1978, Frank et al. 1992). A citation of an unpublished report from a survey of plant parasitic nematodes 

(Braithwaite 1973) indicates that someone collected these common but oft-overlooked animals on Montserrat in the 

early 1970’s, most likely someone named C. W. D. Braithwaite from Trinidad. An original copy of this paper has not 

been located, but it contains the earliest records of non-medical nematodes from Montserrat. 

Montserrat has benefited from its proximity to the French Antilles, with several French scientists visiting 

Montserrat while working on Guadeloupe. The French entomologist Jacques Bonfils reported on some Montserrat 

species (Bonfils 1969), and he may have collected on the island during one of his visits to the French West Indies 

(Bonfils 1969). Specimens collected by Pére (Father) R. Pinchon and P. Enrico in December 1967 formed the basis for the 

first list of butterflies for the island (Pinchon & Enrico 1969). Malacologist Jean-Pierre Pointier, of the Université de 

Perpignan, collected aquatic snails in 1974 (Pointier 1975), apparently on a side trip from work in the French Antilles. 

His work was focused on the intermediate hosts of schistosomiasis. Fortuné Chalumeau of the Institut de Récherches 

entomologiques de la Caraïbe in Guadeloupe, collected insects, mostly beetles, on Montserrat in March 1982, December 

1983 and March 1984. His material is now in the collection of the Conseil Général de la Guadeloupe at the Institut 

National de la Recherche Agronomique (INRA), Petit-Borg, Guadeloupe. Also from Guadeloupe, the husband/wife 

team of entomologists Bernard LaLanne-Cassou and Jeanne le Duchat d'Aubigny collected on Montserrat in December 

1983. Their Montserrat material is also at INRA-Guadeloupe. The collections at INRA constitute the third largest insect 

collections from Montserrat. 

Following the schistosomiasis work of Pointier, M. A. Prentice collected aquatic snails in 1977 [identified as 

“Prantice” in Stevens and Waldmann 2001] (Prentice 1980) as a Rockefeller Foundation staffer based in St. Lucia. 

The English coleopterist Jonathan Cooter (1949- ) published (Cooter 1983) a brief report on a collection he made 

with his father (the designer of postage stamps, including many for Montserrat) John Edward Cooter (1913-2001) in 

August, 1975. He listed 20 species of beetles, 19 of them first records (Table 4). This represented only a portion of their 

specimens, all of which are deposited in the Natural History Museum, London (pers. com. J. Cooter). These collections, 

combined with others in London, are probably fifth in size among Montserrat insect collections. Coleopterist Robert 

Eugene Woodruff (1933 - ) of the Florida State Department of Agriculture visited the island in June of 1977, and ran an 

ultraviolet light trap at Fox’s Bay. His collections in the Florida State Collection of Arthropods (Gainesville), (along 

with records from Baranowski and Walker, below) form the basis for several Montserrat records included in Woodruff 

et al. (1998). Another coleopterist, Richard Stuart Miller (1945 - ) collected a few specimens while vacationing on 

Montserrat in July 1981. Most of his material is now in the West Indian Beetle Fauna Project collection in Bozeman, 

with some remaining in his private collection. 

One of the few synthetic works specifically on the invertebrates of Montserrat was published by Schwartz and 

Jimenéz (1982) on the island’s butterflies. The new material was based mainly on collections made between June 1980 

and February 1981 by Peter L. Richel and Geoffrey L. Blattin, who were resident on Montserrat at the time, attending 

medical school at the American University of the Caribbean. Additions to the butterfly fauna were made by Schwartz 

(1991), based on collections by herpetologist Robert W. Henderson in November 1987, and José Escobio in May 1990. 

This material is now deposited in the Milwaukee Public Museum. 

Hemipterist Richard Matthew Baranowski (1928- ) of the University of Florida, accompanied by his wife Helen 

B. Venn Baranowski, collected on Montserrat in June-July 1991, July-August 1992, and June 1993 as part of the work 

that led to a major volume on the Lygaeidae of the West Indies (Slater and Baranowski 2005). This material is largely 

housed in his private collection, with some in the Charles W. O’Brien collection and perhaps some at the FSCA. 

Baranowski’s collection also contains Montserrat material collected at ultraviolet lights run by P. Jeffers at Brades, in 

October 1992 and April-May 1993, as well as at Groves, in June 1993. No further information is available for Jeffers. 

Thomas J. Walker, University of Florida, visited Montserrat to collect Orthoptera in 1992. His material is in his 

private collection in Gainesville, and may be the source for some of the Montserrat records in Woodruff et al. (1998). In

August, 1992 and again in August 1993, another husband/wife team, Lee Denmar Miller (1935 - ) and Jacqueline 

Yvonne Miller (1944 - ), collected butterflies on the island, and included their records in their book (Smith et al. 1994). 

Their specimens are in the Florida Museum of Natural History, Gainesville. 

Canadian entomologist Christopher Kenneth Starr, Senior Lecturer at the St. Augustine campus of the 

University of the West Indies (Trinidad) collected briefly on the island in July 1994, and his small batch of material is in 

the UWI collection. [This collection may also house unreported specimens from Ballou, Fennah, Bennett or others.] 

While serving as a Fulbright Scholar at the University of the West Indies (Cave Hill) T. David Bass (1956 - ) of 

the University of Central Oklahoma (UCO) visited Montserrat in June 1996 to collect aquatic invertebrates. He 

obtained the first, and to date, the only, known mayfly in Lawyer’s River. That specimen is deposited at Texas A&M 

University (Baumgardner et al. 2003), but material of 24 more species he collected, including snails, decapods, 

ephemeropterans, odonates, hemipterans, trichopterans, coleopterans and dipterans are in the Caribbean Invertebrate 

Freshwater Invertebrate Collection at UCO (Bass 2003). 

Germans Michael Stevens and George Waldmann, from the Heinrich-Heine-Universität (Germany) and 

University of Coventry (United Kingdom) respectively, collected more extensively on the island in 1999, preparing 

their checklist of the fauna of Montserrat (Stevens and Waldmann 2001). They were assisted by several residents, 

including Bridgett Beatty and Ingrid Rapuano. Much of their insect material was donated to the West Indian Beetle 

Fauna Project, reported below, while other portions were distributed to specialists. 


The number of people who have helped with this 

project is very large, and perhaps it is best to start by 

thanking the People of Montserrat, who as a whole so 

graciously welcomed us, helped us, and encouraged us 

in our work. Never have we worked with such a 

pleasant population of wonderful people. If we leave 

someone out below, it is because of the limitations of 

space, not for lack of gratitude. To all the people who 

opened their homes, businesses offices and even their 

cars to us, provided hospitality and forbearance, we say 

Thank You. 

This project built upon our initial work on the 

effects of volcanic ash on the food of the Montserrat 

oriole. That first multi-year project was the idea of, and 

because of the commitment by, Geoff Hilton of the Royal 

Society for the Protection of Birds. He filled a variety of 

roles, including funding manager, project advocate, field 

companion and helper, friend and colleague, and we 

thank him for everything he has done to make this 

project possible. 

The project would not have been physically 

possible without the Montserrat Department of 

Agriculture and its Forestry Division, especially Lloyd 

Martin, James Boatswain, John Martin, James Daley, 

Lloyd Aymer and Gerard Grey. They cut red tape, 

made things happen, toted the fogger out to every site, 

every time, ran the fogging, and generally kept us going 

with good cheer and encouragement, not to mention 

belief in what we were doing. Philemon Murrain and 

Calvin Fenton were part of this cadre of field support as 

well. This group of men who work so hard to protect 

Montserrat’s biodiversity became our good friends, and 

we dedicate this chapter to them. 

The Montserrat National Trust provided critical 

logistic support and transportation, and we thank Lady 

Eudora Fergus, Jean White, Donna Henry, Stephen W. 

Macnamera, and Ann-Marie Graham. The Montserrat 

Volcano Observatory staff helped with helicopter time, 

advice, and general good ideas, especially, Simon 

Young, Peter Dunkley, Gill Norton, and Racquel Syers. 

Ann Krakower faithfully ran traps for us, helped by her 

mother Rosalie Burrows and Bridgett Beatty. Chris 

Bowden, Joah Madden, Bo Dalsgaard, Richard Allcorn, 

Mark Hulme, and Sarah Sanders of The Royal Society 

for the Protection of Birds all helped with the field work 

and other aspects of this project. Thomas Burkett of The 

Community College of Baltimore County accompanied 

MAI to the summit of Katy Hill, and brought him down 

in one piece. Montana State University students Kelvin 

Guerrero, Kenneth Puliafico, Vincent Martinson, Patrick 

Hughley, Levi Lehfeldt, and Robert Semple helped with 

extensive field work, while Sarah Jackson mounted a 

very large number of the specimens. 

Bridget Beattie, Nancy Hermany, Carol and 

Cerdic Osborne, Susan & Eddie Edgecombe, Betty Dix, 

Ingrid Rapuano, and Gerry and Helen Cooper gave us 

permission to collect and/or run traps on their 

properties, as well as other courtesies too numerous to 

detail here. Advice, encouragement, information and 

good company were provided by Sir Howard Fergus of 

the University of the West Indies, Anthony Hill of DFID, 

Elivina Farrell of Montserrat Forestry, Trevor Howe of 

Montserrat Environmental Health, and Robert Krakower 

of Palm Loop. Governor Anthony and Mrs. Jane 

Longrigg, and Governor Deborah Barnes Jones, and 

members of their staffs Geoff Patton and David Hume 

facilitated many aspects of our work, including 

permission to work in the exclusion zone. 

In addition to the assistance while on Montserrat, 

many more people helped from off-island. Fortune 

Chalumeau and Bernard Brochier of Guadeloupe 

opened their homes and knowledge of West Indian

material at IREC. For permission to use their 

photographs, thanks to Kenneth Puliafico, Quentin 

Bloxam, and Gerardo Garcia. For reviews of parts of the 

manuscript, discussions of techniques, and help with 

literature: Richard Hurley, Richard Miller, Kevin 

O’Neill, Christopher Marshal, Andrew Cline and the 

interlibrary loan staff of MSU’s Renné Library. Michael 

Stevens, of Heinrich-Heine-Universität, kindly donated 

material from his own field work on Montserrat.

Several people from the Durrell Wildlife 

Conservation Trust deserve a great round of thanks for 

their efforts on our behalf: John Fa for inviting us into 

this project; Richard Young for managing it and for his 

patience waiting for the manuscript, as well as the 

editing of this volume; Sarah Seymour and Quentin 

Bloxam have acted as effective advocates for this 

project’s initiation and completion. 

Funding for this project was provided by the 

Durrell Wildlife Conservation Trust, the Montana 

Agricultural Experiment Station of Montana State 

University and MSU’s Undergraduate Scholars 

Program, in cooperation with the Montserrat National 

Trust and Montserrat Forestry and Environment 

Division of the Montserrat Department of Agriculture. 

Earlier work that contributed so strongly to this project 

was funded by the Montserrat Forestry and 

Environment Division of the Montserrat Department of 

Agriculture, the United Kingdom Foreign and 

Commonwealth Office, The Royal Society for the 

Protection of Birds, and the Montserrat National Trust.

5. Amphibians and reptiles of the Centre Hills 

R. P. Young & A. Ogrodowczyk 

5.1. Diversity and status of amphibians and 

reptiles in Montserrat 

Three species of amphibian and 11 terrestrial 

reptiles have been recorded on Montserrat (see Table 

5.1) (Schwartz & Henderson, 1991; Malhotra & Thorpe, 

1999), although five of these species are thought to be 

human‐sponsored introductions. The native species 

assemblage is generally typical of the Lesser Antillean 

region, with two species of frog, two species of snake 

and five species of lizard. Six island endemics at species 

or subspecies level occur, including a tree lizard (Anolis 

lividus), ground lizard (Ameiva pluvianotata), dwarf gecko 

(Sphaerodactylus fantasticus ligniservulus), galliwasp 

(Diploglossus montisserrati) (Fig. 5.1), racer (Alsophis antillensis 

manselli) (Fig 5.3) and blind snake (Typhlops 

monastus monastus). The regionally endemic mountain 

chicken (Leptodactylus fallax) (Fig. 5.2), and a tree frog 

endemic to the Lesser Antilles (Eleutherodactylus johnstonei) 

also occur in Montserrat. The final native species 

is the turnip‐tailed gecko (Thecadactylus rapicauda), which 

has a widespread range in Central and South America. 

The high level of endemism in Montserrat’s amphibians 

and reptiles is typical of this taxonomic group across the 

Lesser Antilles. The number of species is higher than 

expected given the size of the island, as predicted by 

species‐area curves for the Lesser Antilles (Ricklefs & 

Lovette, 1999), and therefore, within the region, Montserrat 

can be considered to have high herptile species 

richness per unit area. This is probably due to high 

habitat diversity, thought to be the main driver of species 

richness in this taxonomic group in the Lesser Antilles 

(Ricklefs & Lovette, 1999). 

All the native species occur within the Centre 

Hills which, with the exception of the A. pluvianotata 

(which tends to occur in open and dry habitats), probably 

represents the most important site for the island endemics 

globally and the other native species at the national 

level. The amphibian and reptile species assemblage 

of the Centre Hills is of high conservation value 

due to its high endemicity and the occurrence of two 

Critically Endangered species, D. montisserrati (Day, 

1996) and L. fallax (Fa et al., 2004). D. montisserrati was 

until recently only known from a single specimen collected 

from the Woodlands area of the Centre Hills in 

the 1960s. After the volcanic activity in the mid 1990s it 

was thought to be potentially extinct. However, in 1998 

a second D. montisserrati was observed in the same locality 

by a member of the Montserrat Department of Environment. 

In 2004, a third individual was also spotted in 

Woodlands and three unconfirmed observations by local 

residents have been subsequently reported 

(Ogrodowczyk et al., 2007). The concentration of these 

sightings in this small area of moist forest has led to the

assumption that D. montisserrati is highly restricted in 

range (possibly < 1 km 2 ) and therefore extremely rare, 

although this assumption needs testing with a systematic 

survey. Over the past few years search effort at this 

site has probably been disproportionately high compared 

with other Centre Hills sites. It is thought to be 

semi‐fossorial and cryptic in behaviour and therefore 

extremely difficult to detect even when present. D. mon‐

tisserrati is the only member of the Anguidae family in 

the Lesser Antilles, with its closest relatives occurring in 

the Greater Antilles, and therefore represents a biogeographical 

enigma (Malhotra & Thorpe, 1999). 

L. fallax, one of the largest frogs in the western 

hemisphere, once occurred on six islands in the Lesser 

Antilles but is now only found on Montserrat and Dominica. 

The population on Dominica has undergone 

dramatic decline due to a disease outbreak of Chytridiomycosis 

in the early 2000s, and is severely threatened 

with extirpation. The recent eruptions of the Soufrière 

volcano in Montserrat is thought to have destroyed 

roughly 60% of Montserrat’s wetter forest habitats. It is 

unclear how much of this forest was occupied by L. fallax 

but some population decline in Montserrat is likely following 

the volcano. L. fallax is now probably only found 

in the Centre Hills, which probably supports the largest 

and globally most important population as despite recent 

extensive sampling, no evidence of Chytridiomycosis 

has been found (Garcia et al., 2007). Anecdotal evidence 

suggests that within the Centre Hills the L. fallax population 

is not overall in major decline (see Box 4: Mountain 

chicken monitoring) and it appears relatively widespread 

in the mesic and wet forest. However, there is evidence 

of severe localised declines of mountain chickens in the 

Centre Hills, possibly due to over‐exploitation. No 

quantitative data on the actual size of the L. fallax population 

in the Centre Hills exist. 

E. johnstonei is ubiquitous in Montserrat and is 

very abundant in the moist forests of the Centre Hills in 

particular. S. fantasticus ligniservulus and A. lividus are 

also widely distributed and abundant in the Centre Hills 

and occur in the dry as well as moist forest. T. rapicauda 

is less well known but not considered to be locally 

threatened and is associated with forest and scrub habitats. 

As mongooses have not been introduced to Montserrat 

A. antillensis manselli is thought to be generally 

abundant, particularly in the Centre Hills. Mongooses 

have extirpated other species of racer on other Lesser 

Antillean islands, e.g. Alsophis antiguae on mainland Antigua. 

A. pluvianotata has also probably benefited from 

the absence of this invasive mammal but is thought to 

have undergone a severe population decline as a result 

of habitat destruction after the volcanic eruption 

(Malhotra & Thorpe, 1999). It is considered to be relatively 

abundant in remaining dry open habitats, including 

the dry forest in the Centre Hills. T. monastus 

monastus (Fig. 5.4) is fossorial and highly cryptic and 

therefore information on its abundance and distribution 

is scant. 

Common to other taxonomic groups, amphibians 

and reptiles face a number of threats typical of Caribbean 

islands, mainly from invasive mammals and habitat 

destruction (through both natural events and urban 

development and agriculture) which have been outlined 

in more detail in the Introduction. Both the Critically 

Endangered mountain chicken and galliwasp possess 

behavioural and morphological traits that predispose 

them to being vulnerable to the effects of rat predation, 

as well as pigs and cats. It is suspected that rats will 

predate juvenile L. fallax and even attack adults, which 

have been seen with wounds that appear to have been 

inflicted by rats (see Fig. 5.5). 

However, amphibians, and L. fallax in particular, 

also face a number of unique threats. Firstly, as amphibians 

have permeable skin they may be susceptible to 

the toxic effects of volcanic ash which has regularly 

fallen on the Centre Hills since 1995. Under certain climate 

conditions (i.e. no rain), falling ash can lead to potentially 

damaging increases in environmental acidity 

levels which may have both short and long term effects 

on mountain chickens. Secondly, L. fallax have historically 

been extensively hunted (legally) for food on Montserrat. 

At present it appears that few people regularly 

hunt mountain chickens (McCauley & Mendes, 2006) but 

no quantitative data exist on the number of frogs 

hunted. It is suspected that hunting activities can result 

in the near complete removal of adult frogs from localised 

areas. However, perhaps the most severe threat to 

the persistence of mountain chickens in the Centre Hills, 

and more widely, is Chytridiomycosis. This disease can 

be transmitted between geographical regions via the 

human sponsored movement of amphibians and fungal 

spores contained in soil on boots, equipment and unwashed 

produce. Currently fruit is transported to Montserrat 

by boat from Dominica and this cargo is likely to 

contain small amphibians such as tree‐frogs. If Chytridiomycosis‐infected 

tree‐frogs survive the journey and 

escape from the shipment containers there is a high risk 

this disease will be introduced into the amphibian populations 

in Montserrat, which would have extremely se‐

once during the day. These surveys included intensive 

searching through leaf litter and refugia as well as visual 

inspection of the ground and vegetation. In total, approximately 

400 and 390 man hours of diurnal and nocturnal 

fieldwork respectively was conducted. Incidental 

observations of all species except E. johnstonei and S. 

fantasticus away from line transects were recorded. 

All amphibian and reptile species known from 

Montserrat, except Mabuya bistriata and Geochelone carbonaria 

(these two species are suspected to have now 

disappeared from Montserrat), were observed during 

the CHBA (i.e. during line transect surveys, dedicated 

searches and incidental observations). The number of 

sightings and encounter rate of amphibian and reptile 

species recorded during the line transect survey are 

given in Table 5.2. 

From the survey data it is clear that by far the 

most abundant species in the Centre Hills is E. johnstonei, 

which was recorded at all sample points and constituted 

90% of all herptile observations in the wet season (see 

Table 5.2). S. fantasticus was the second most frequently 

observed species and occurred at 77% of sample points. 

A. lividus was widely distributed (recorded at 93% of 

sample points) but was not as abundant in the Centre 

Hills as expected. Anoles typically occur at very high 

density in forests in the Lesser Antilles. For example, in 

St Lucia, Anolis luciae was encountered at a rate of 18.7 

anoles 100m ‐1 in a patch of dry forest and at 90.9 anoles 

100m ‐1 in xeric scrubland on a small offshore island (K. 

Varnham, unpubl. data). The dry season encounter rate 

of 2.3 anoles 100m ‐1 in the Centre Hills is an order of 

magnitude lower than these estimates. Populations of 

anoles are likely to fluctuate widely in size and so these 

estimates of relative abundance may represent a low 

point in a longer term trend. However, as they are so 

low, it does raise suspicions that the species is being 

held well below carrying capacity by a pressure such as 

predation by rats and we recommend this requires further 

investigation. Anoles are important prey species for 

a number of predators, such as A. antillensis, and therefore 

any reduction in their numbers could have knockon 

effects at higher trophic levels. 

L. fallax were frequently heard along nearly all 

line transects surveyed at night during the wet season 

which coincides with their breeding season when males 

call regularly. They were however rarely seen along the 

line transects. In the dry season L. fallax are congregated 

in ghauts and not regularly calling and were therefore 

recorded very infrequently at this time of year (for more 

information on L. fallax see Box 4: Montserrat mountain 

chicken monitoring programme). Relatively few observations 

of A. antillensis (n = 8) and T. rapicauda (n = 5) were 

made during the line transect survey, which probably 

reflects their low detectability rather than their scarcity. 

A further 12 and 7 incidental observations were made of 

A. antillensis and T. rapicauda respectively during the 

CHBA. Racers are highly threatened in the Lesser Antilles 

(e.g. Antigua, St Lucia) so a healthy population of A. 

antillensis in the Centre Hills would be of conservation 

importance. A single incidental observation of the 

highly cryptic T. monastus monastus was made during 

the wet season phase of the CHBA in the Fogarthy area 

of the Centre Hills (with a second incidental observation 

of two individuals in the National Trust office grounds). 

T. monastus across the Lesser Antilles are typically difficult 

to locate without specialized search techniques (e.g. 

digging) so it is impossible to draw any conclusions on 

the status of the species in the Centre Hills. 

Only 10 observations of the exotic B. marinus 

were recorded during the line transect survey, which 

was far lower than expected as they were previously 

thought to be widespread in the Centre Hills forest. 

They appeared to be relatively scarce in the forest interior 

but were frequently seen along trails and tracks and 

also in ghauts. Four incidental observations of Iguana 

iguana were made in the Fairy Walk/Jack Boy Hill area

Fig. 5.6. Location of galliwasp sightings (red triangles) in Woodlands Spring (the forest reserve lies to the east of black line 

which represents the current boundary) 

with one further sighting in Fogarthy. I. iguana was 

regularly seen away from the Centre Hills, particularly 

near to the coast. Hemidactylus mabouia was not observed 

in the Centre Hills but was widespread and common 

in areas of human habitation. 

Following the historical sightings of D. montisserrati 

in the Woodlands area of the Centre Hills a series of 

dedicated searches of the site were made during the dry 

season survey of the CHBA. On 26 th January (1915 

hours), an adult D. montisserrati was observed, only the 

fourth confirmed sighting of this species, providing evidence 

of its continued existence. Woodlands Springs is 

approximately 10 hectares of mesic forest interspersed 

with a small number of houses, large gardens and agricultural 

plantations (see Fig. 5.6), and thus people and 

domestic animals, including cats and dogs, are present 

in the area. Topography is steep and rocky 

(approximately 240 metres asl), and recorded annual 

rainfall is roughly 1500 mm. The galliwasp was found 

under a stone and caught by hand, examined briefly, 

then measured and weighed. It had a snout‐vent length 

of 18 cm, a tail length of 23 cm and was 170 g in weight. 

A second adult D. montisserrati was seen in 

Woodlands Springs on the 5 th February (1830 hours), 

approximately 20‐30 m from the location where the first 

individual was found. The animal was found within the 

roots of a tree with only its head visible but immediately 

retreated out of sight into the root system. It was observed 

again shortly afterwards and was followed for 

approximately 20 minutes walking across the forest floor 

in an attempt to examine its behaviour and to identify 

potential cues to aid its detection. The D. montisserrati 

appeared to be very sensitive to disturbance and would 

cease moving in response to any movement or noise 

made by the observer. Another sighting of what was 

presumed to be the same individual was made in exactly 

the same location on the 8 th March (1800 hours). It is 

noteworthy that all of the recent and most of the historical 

sightings have occurred around dusk, despite searching 

at all times of day and night, which suggests D. montisserrati 

may be crepuscular. 

The CHBA survey covered the whole Centre 

Hills and this represents the first multi‐species systematic 

survey of reptiles and amphibians dedicated to this 

area. Furthermore, the Montserrat Department of Environment 

has conducted regular nocturnal fieldwork 

throughout the area since 1998 as part of the mountain 

chicken monitoring programme. However, D. montisserrati 

has only ever been recorded in one site. This lends 

weight to the hypothesis that D. montisserrati does indeed 

have a highly restricted range and is therefore extremely 

rare. As Woodlands Springs does not appear to 

be markedly different in terms of topography, climate 

and habitat structure to other nearby forest areas, it is 

not clear why D. montisserrati would be restricted to 

such a small site. The rocky terrain may provide sufficient 

refuge from rat (and cat and pig) predation for a 

population to persist. 

Data on the ecology and natural history of D. 

montisserrati are sparse. As a first priority, quantitative 

information on distribution and population abundance 

is required to evaluate its status and inform conservation 

action. An effective and systematic survey technique 

needs to be developed and tested. Although the 

species is detectable by sight (and the noise of them 

moving through leaf litter provides a cue to their pres‐ 

_______________________________________________________________________________________________________________________ 


94

Fig. 5.7. Map of the mean dry season encounter rate of L. fallax between 1999 and 2005 

ence), the cryptic nature of D. montisserrati and their 

apparent sensitivity to human presence will result in 

low encounter rates, thus potentially precluding meaningful 

sample sizes. Pit fall trapping has been used in 

surveys of other galliwasp species, e.g. Celestus crusculus 

and C. duquesneyi in Jamaica (Wilson & Vogel 2000), but 

in the current field site, such capture methods may be 

problematic because of the presence of rats (Rattus rattus 

and R. norvegicus) and domestic cats and dogs, which 

may predate upon any trapped animals. 

Given the likely scarcity and vulnerability of D. 

montisserrati a Species Action Plan needs to be developed 

and implemented, including a programme of field 

research, habitat protection and potentially invasive 

mammal control. Rats are common in the Centre Hills 

(see Chapter 8: Rats in the Centre Hills) for more information) 

and may strongly limit the population growth of D. 

montisserrati and an experiment to quantify their impact 

would likely to prove informative for the design of control 

programmes. Protection of the forest in the Woodlands 

Spring site from further development is required 

and provision for this should be incorporated within the 

Centre Hills management plan along with other required 

conservation initiatives. However, the galliwasp 

sightings fell outside the existing forest reserve boundary 

and therefore currently the site has no protection 

(see Fig. 5.6). The Woodlands site should be considered 

as a strict conservation zone to safeguard this species 

whilst data on its abundance and distribution are gathered. 

However, given the probable vulnerability of D. 

montisserrati direct intervention to save the species, such 

as captive breeding, may be necessary. 

The number of native herptile species recorded at 

sample points varied between two and six. Only at one 

sample point (#81) in the west of the Centre Hills, between 

Woodlands and Salem, were all six regularly occurring 

native species recorded (i.e. those listed in Table 

5.2). Five species were recorded at five sample points, 

which were situated on the western and eastern flanks 

of Centre Hills. These high species richness sample 

points were all positioned in mesic forest and near the 

boundaries with wet forest and dry forest (at intermediate 

altitudes between 240 and 476m). There was a tendency 

for recorded species richness to be lower at the 

high altitudes (Fig. 5.8: NB. due to health and safety reasons 

it was not possible to survey four of the high altitude 

sample points at night, so therefore survey effort at 

these points was reduced which may have resulted in 

lower species richness). The CHBA data suggested the 

existence of some species habitat associations. S. fantasticus 

appeared to be at much higher densities in dry forest 

(an order of magnitude higher) than in mesic and 

wet forests. A. lividus was at higher density in dry and 

mesic forests. All observations of T. rapicauda were in 

mesic forest and all A. antillensis sightings were in wet 

and mesic forests (> 310m asl). There was no suggestion 

that E. johnstonei was associated with any particular 

habitat and was highly abundant in all three major forest 

types. 

L. fallax are traditionally thought to show a preference 

for mesic and wet forest in Montserrat. Figure 5.7 

shows how the encounter rate of L. fallax along monitoring 

transects varies across the Centre Hills. Fairy Walk 

has the highest recorded encounter rate of L. fallax and is 

likely to represent the most important site for this spe‐

cies in the Centre Hills. L. fallax encounter rate was also 

high in Corbett Spring, Sappit River, Killiecrankie, Bunkum 

River and Pelican Ghaut. It appears to be most 

abundant in the east and south of the Centre Hills. 

Analysis carried out elsewhere (J. Fa, pers. comm.) revealed 

that the body condition of L. fallax tended to be 

higher in the east of the Centre Hills than in the west. 

This would suggest that the L. fallax population in the 

east is in better condition, both in terms of population 

size and individual growth rates. It is not understood 

why this would be the case, but may be due to the increased 

difficulty of accessing the eastern sites for hunting 

compared to the west. For more information on L. 

fallax see Box 4: Montserrat mountain chicken monitoring 

programme 

In summary, the mesic forest appears able to support 

both the species that favour the dry and also the 

wet forest and is therefore likely to be the most valuable 

habitat type for amphibians and reptiles within the Centre 

Hills. However, it is noteworthy that the wet and 

dry forests were both under‐sampled in comparison to 

the mesic forest. We have tentatively identified two sites 

of high amphibian and reptile species richness in the 

Centre Hills (see Fig. 5.8). Firstly, there appears a relatively 

large area of high richness in the west and northwest 

of the Centre Hills, particularly in the forest directly 

to the east of Salem and Woodlands. The Woodlands 

site where the D. montisserrati individuals were 

found is located near to the western site of high richness 

(see Fig. 5.8) which further increases the potential value 

of this area for amphibians and reptiles. Secondly, there 

appears to be a site of high richness in the Jackboy Hill 

and Fairy Walk area to the east of the Centre Hills. Relative 

to other taxa, such as birds or bats, herptiles on islands 

tend to have more specific habitat requirements 

and therefore a range of habitats needs to be managed 

for conservation to protect the herptile community. This 

should include substantial areas of the least disturbed 

dry forest which is under‐represented in the region delineated 

by the historical forest reserve boundary, as 

well as mesic and wet forest. If an area running from the 

elfin woodland at the peaks of the Centre Hills in an 

eastward direction down to the dry forest at sea‐level 

was designated for biodiversity conservation, this would 

ensure all elevations and therefore a complete range of 

habitats be represented in the protected area. Such an 

area would encompass the Jack Boy Hill‐Fairy Walk area 

of high richness, and the sites of highest L. fallax abundance. 


Agnieszka Ogrodowczyk is grateful to the Montserrat 

Department of Environment for providing so 

much support during the amphibian and reptile survey. 

Especially, I want to thank Lloyd Martin for organising 

my work schedule so perfectly, and Philemon Murrain 

and Calvin Fenton for spending many hours in the field 

with me. I also want to thank James Daly, John Martin, 

James Boatswain, Lloyd Amer and Jervain Greenaway 

for teaching me how to work in Montserrat. I am grateful 

to Carole McCauley for caring for me during my stay 

in Montserrat and to Matt Morton for his ever‐friendly

Box 4. The Montserrat mountain chicken monitoring programme 

Since 1998 the Montserrat Department of Environment have monitored the Centre Hills mountain chicken 

population, using a scheme originally designed by Flora and Fauna International. From 2003 onwards, Durrell Wildlife 

Conservation Trust has provided assistance to the Montserrat Department of Environment on the design and 

implementation of the monitoring programme, training on wildlife disease sampling and the analysis of monitoring 

data. 

The monitoring programme (which is separate to the CHBA) consists of approximately 20 line transects of 200m 

in length subjectively placed along ghauts and trails to provide a reasonable spatial coverage of the Centre Hills. The 

number of frogs seen along each transect is recorded, along with data on each individual including, weight, snout‐ventlength, 

sex and condition. An encounter rate (number of frogs seen per 100m of line transect) is calculated, which 

serves as an index of abundance. Surveys are carried out between two and four times per year. A preliminary analysis 

of the field data is reported here along with a number of brief recommendations for improving the reliability of the 

monitoring programme. 

Some concern had been raised that small juvenile frogs (< 10 cm SVL) were not recorded on the data recording 

forms before 2003, and were recorded thereafter, and therefore a change in data collection protocol may have lead to 

the interpretation of misleading trends. Fig. 5.10 shows the distribution of snout‐vent length (SVL) data in the dry 

season before and after 2003. In both time periods, only a very small proportion of observations (1.6% each) were made 

of frogs

Box 4. The Montserrat mountain chicken monitoring programme 

population. Figure 5.13 shows the spatial variation in the trend of the mountain chicken population between 1999 and 

2005. There are five sites where there is a positive trend (slope of linear regression line) across this time period in the 

recorded encounter rate. The most positive trend is found in Fairy Walk followed in order by Corbett Spring, Bunkum 

River, Pelican Ghaut and Bottomless Ghaut. Four of these sites are in the east and north east of the Centre Hills. This 

underlines the importance of the east of the Centre Hills for mountain chickens where populations are larger and 

growing, and individual frogs are in better condition. Conversely, mountain chicken populations appear to be less 

abundant in the west, not increasing in size and in some ghauts seem to have disappeared. It is not certain whether 

this is due to the impact of hunting, predation by invasive mammals, difference in habitat quality or some other factor. 

A questionnaire survey of mountain chicken hunters in Montserrat revealed that a single individual is responsible for 

the majority of hunting and that he most frequently hunts in the western ghauts (McCauley & Mendes, 2006). This 

does suggest that the east‐west difference in abundance, population trend and body condition of mountain chickens 

may be due to the offtake from hunting. Given the range and severity of threats to the mountain chicken, and its low 

reproductive potential, we recommend that unregulated hunting of mountain chickens be actively discouraged until a 

positive trend in population size is detected 

with certainty or quantitative data on the vital 

rates of mountain chickens exist with which 

to reliably estimate quotas for sustainable 

harvesting. 

Further analysis of the monitoring 

data is needed to estimate the power of the 

monitoring programme to detect trends of

3.5

certain magnitudes over certain time periods 

and to make recommendations to improve its 

1.5 

sensitivity. A data collection protocol is 1 

needed to standardised methods of data 

collection to maximise data reliability. It 0.5 

should be noted that detection probability of 

mountain chickens is not estimated as part of 

the mountain chicken monitoring 

programme. Hence there is the potential for 

unquantified variation in detection 

probability resulting in changes in the index 

of abundance even when population size 

remains constant. This is a problem common 

to the majority of monitoring schemes relying 

on indices of abundance. 

However, we believe that given the 

level of threats to the mountain chicken in the 

Centre Hills it is vital that monitoring is 

continued for the foreseeable future. The 

current monitoring programme is likely to be 

able to detect any sharp declines in 

abundance through a potential outbreak of 

Chytrid fungus. Monitoring is also important 

so the impact of the Centre Hills management 

plan on this species can be quantified but 

changes to improve its sensitivity will need to 

be made to enable this. We recommend a 

minimum effort of one survey in the dry 

season and one in the wet season per year. It 

is imperative that surveys are conducted at 

the same time of year to remove the 

confounding effects of seasonal changes in 

behaviour on the estimates of encounter rate.

6. Birds of the Centre Hills 

G. M. Hilton 

6.1. Diversity and status of birds in Montserrat 

6.1.1. The Centre Hills avifauna 

The bird community of the Centre Hills is species‐poor, 

but of high conservation value. The avifauna 

comprises resident and wintering neotropical landbirds. 

There are no waterbirds of any kind, except for a small 

number of striated herons Butorides striatus along the 

larger ghauts. 

Taxonomically, the forest bird community is typical 

of Lesser Antillean islands. Pigeons and doves 

(Columbidae), hummingbirds (Trochilidae) and mimic 

thrushes (Mimidae) are particularly conspicuous. Raptors 

(Falconiformes) are scarce, owls (Strigidae) and 

woodpeckers (Picidae) are absent. Parrots (Psittacidae) 

are also absent, although it is likely that an endemic 

Amazona parrot species, similar to those surviving on 

Dominica and St Lucia, occurred at one time and is now 

extinct (Reis and Steadman, 1999)

Resident landbirds 

Figure 6.2. Pearly-eyed thrasher Margarops fuscata. 

(Photo: G. Hilton, RSPB) 

In general, and in common with other Antillean 

island bird communities (Raffaele et al., 1998), the bird 

species tend to be habitat (and dietary) generalists, relative 

to tropical forest birds in mainland Central and 

South America (Table 6.1). 

The avifauna is dominated by omnivores. The 

majority of the resident bird species eat a combination of 

fruit and insects, plus, variously, nectar, seeds and small 

vertebrates. The predominance of generalists may be a 

response to environmental conditions on Montserrat. 

The island’s small area means that populations that occur 

at low density are likely to be very small, and hence 

prone to stochastic extinction. Furthermore the relatively 

frequent catastrophic disturbances – notably hurricanes 

and volcanic eruptions ‐ mitigate against developing 

specialist habitat or diet selection: opportunism is likely 

to be strongly selected. 

Predatory birds are rare in the Centre Hills. The 

two characteristic hawks of the Antilles are both absent 

in the Centre Hills: the broad‐winged hawk Buteo platypterus, 

which is common in most of the Lesser Antilles, 

occurs only as a rare passage migrant on Montserrat 

(despite being abundant in Antigua); the red‐tailed 

hawk Buteo jamaicensis, common in the Greater Antilles, 

reaches its southern limit in St Christopher/Nevis 

(Raffaele et al., 1998). The only resident terrestrial raptor 

in Montserrat is American kestrel Falco sparverius, which 

is essentially an open country species and is scarce in the 

Centre Hills. It is rarely seen in closed forest, although 

observations have been made of this species pursuithunting 

Montserrat orioles Icterus oberi (unsuccessfully) 

under closed canopy woodland in the Centre Hills. Both 

merlins Falco columbarius and peregrines Falco peregrinus 

do occur in the Centre Hills as winter visitors, but are 

uncommon. As in most of the Lesser Antilles, owls are 

absent. Pearly‐eyed thrashers Margarops fuscata, which 

are super‐abundant throughout the Centre Hills may 

predate small passerines (Arendt, 2006), though they are 

more known as nest predators.

Migrant landbirds 

In terms of numbers of species, the majority of 

Montserrat’s landbirds are in fact passage migrants and 

winter visitors that breed in North America (Table 6.2). 

The migrants are dominated by Parulidae (woodwarblers), 

with a small number of other families represented. 

However, although relatively rich in species, the 

migrant avifauna is very thinly spread on Montserrat. 

None of these species have been recorded more than 10 

times during the Centre Hills Bird Monitoring Programme, 

during well over 1,000 point counts, indicating 

that they are all very scarce relative to the resident forest 

bird species (by comparison, even the rarer of the forest 

resident species, such as bridled quail‐dove Geotrygon 

mystacea, brown trembler Cinclocerthia gutturalis and 

Lesser Antillean bullfinch Loxigilla noctis have been recorded 

over 100 times). The passage migrants are probably 

under‐recorded. They are generally inconspicuous 

and quiet, their calls are less well known to the observers, 

and they have not been the focus of a great deal of 

_______________________________________________________________________________________________________________________ 

101 


attention. They are not present during summer census 

work. A number of records in the Forest Bird Monitoring 

Programme are of ‘unidentified warblers’, and we 

suspect that not all identifications are positive; for example 

prothonotary warbler Dendroica citrea seems curiously 

common since Raffaele et al. (1998) report it as 

predominantly a mangrove species that is easily confused 

with yellow warbler Dendroica petechia (common 

on Montserrat). Similarly, there are no records of northern 

waterthrush Seiurus noveboracensis, but several of 

Louisiana waterthrush Seiurus motacilla. Nevertheless, it 

is clear that migrant landbirds are not numerically an 

important part of the Centre Hills’ avifauna, and that the 

Centre Hills, and Montserrat more generally, does not 

support a significant proportion of the population of any 

migrant landbird species. 

Within the Centre Hills, Cape May warbler Dendroica 

tigrina, prothonotary warbler, American redstart 

Setophaga ruticilla and Louisiana waterthrush are the 

only Parulidae species that can currently be regarded as 

regular in occurrence. Merlin, peregrine, Antillean nighthawk 

Chordeiles gundlachii and barn swallow Hirundo 

rustica are all relatively frequent non‐breeding visitors to 

Montserrat, but none are numerous in the Centre Hills. 

6.1.2. Centre Hills birds in the Montserratian context 

The Centre Hills has the largest continuous forest 

block on Montserrat, comprising mostly mesic and wet 

forest at higher altitudes within the forest reserve, with 

dry forest at lower altitudes and mostly outside the reserve. 

There is a very limited area of elfin forest at the 

summits (Chapter 1, Fig. 1.11). Landbirds in Montserrat

Table 6.3. Breeding landbird species in Montserrat, and their distribution among major habitats Population densities of 

Montserrat forest birds 

Abundance estimates are based on the overall mean number of birds detected per point during census work, 1997-2006. 

Zero birds detected = “absent”; 1.0 birds per point = “abundant”. 

Estimates for ‘farms, gardens, settlements’ are subjective assessments, since no census work has been conducted in such 

habitats. 

vary in the degree to which they are forest‐dependent, in 

the degree to which they are able to persist in small forest 

patches away from the main Centre Hills block, and 

in their preference for dry lowland forest or rainforest 

(Table 6.3). Consequently, for some of Montserrat’s landbird 

species, the Centre Hills is the main breeding site on 

Montserrat, while for others it is of less importance. 

With the exception of Caribbean martin Progne 

dominicensis, all of the breeding landbirds in Montserrat 

have been recorded during Centre Hills bird census 

work. 

Species that flourish primarily in open country, 

and for which the Centre Hills represents a relatively 

marginal habitat are American kestrel, zenaida dove 

Zenaida aurita, common ground‐dove Columbina 

passerina, smooth‐billed ani Crotophaga ani and greenthroated 

carib Eulampis holosericus. Species that are most 

abundant in the dry lowland forest areas, and are rather 

rare in the wetter forests of the Centre Hills include 

Lesser Antillean bullfinch, Antillean euphonia Euphonia 

musica (Fig. 6.1), yellow warbler and black‐whiskered 

vireo Vireo altiloquus. Antillean crested hummingbird 

Orthorhyncus cristatus, scaly‐breasted Margarops fusca 

and pearly‐eyed thrasher (Fig. 6.2) and bananaquit Coeroba 

flaveola are common in all habitats in Montserrat, 

including inhabited and farmed areas. Caribbean elaenia 

Elaenia martinica is restricted to forest areas, but appears 

to be equally common in dry‐ and rainforest. 

However, for a number of species, including several 

of conservation concern, mesic and wet forest is the 

key habitat on the island. Montserrat oriole is only 

found in mesic and wet forest. Scaly‐naped pigeon

Table 6.4. Population densities of Montserrat forest birds 

Estimates are made using the December 2004 full census, comprising 146 point-counts, on an even grid throughout the 

Centre Hills. ‘Distance 5.0’ software was used to analyse data. 

1: Assuming an area of 1,440 ha; this is the size of the polygon onto which the point-count grid was originally set out. It does 

not equate to the full area of forested land in the Centre Hills. 

forest thrush Cichlherminia lherminieri and brown trembler 

all occur on occasion in lowland dry forest, but are 

much more abundant in the moist forests of the Centre 

Hills. Data for the other (much smaller) patch of rainforest 

on the island, in the South Soufrière Hills, are very 

scant, but seem to indicate that the bird community is 

similar to the Centre Hills. There is a hint that bridled 

quail‐dove, brown trembler and forest thrush might be 

at lower densities in the southern forest patch, whereas 

Montserrat oriole may be more common. 

6.1.3. Population densities 

We estimated density of the more abundant forest 

bird species using data from the December 2004 full 

census of the Centre Hills (Table 6.4). Distance‐sampling 

(Buckland et al., 1993) was used to convert point‐count 

data into estimates of absolute abundance. 

As always with distance‐sampling of mobile species 

such as birds, careful consideration of the biology of 

the species is required, to assess whether the assumptions 

of the technique are likely to be violated, and hence 

estimates to be incorrect. We suspect that abundance 

estimates for hummingbird species may be too high, 

because they are highly mobile; estimates for these species 

are likely to be rather sensitive to the duration of the 

count. It is quite possible that birds that were not close to 

the observer at the outset move past the observer at 

some point during the course of a 10‐min stationary 

point‐count. We have also argued that early censuses of 

Montserrat oriole tended to over‐estimate numbers because 

birds tended to respond to observers by approaching 

them and calling (Hilton et al. 2003). This phenomenon 

has tended to decline over the years since the census 

began, because the birds have become less naïve to human 

presence. Nevertheless, we suspect that distancesampling 

still over‐estimates oriole numbers to some 

degree. 

All population sizes reported here are essentially 

estimates of the number of individuals in the post‐

eeding populations, since most Montserratian birds 

breed during March‐July. It thus includes juveniles from 

the previous breeding season as well as territorial adults. 

Consequently, it is rather difficult to convert these estimates 

to densities of breeding pairs. 

Along with Antillean crested hummingbird, 

which may be substantially over‐estimated, the pearlyeyed 

thrasher stands out as being exceptionally abundant: 

almost twice as common as all other species in the 

Centre Hills. Numbers of purple‐throated carib (but see 

comments above regarding hummingbirds), Caribbean 

elaenia and bananaquit are also estimated to exceed 

10,000 individuals. The Restricted‐range Species – forest 

thrush, scaly‐breasted thrasher, and Montserrat oriole 

occur in populations of a few thousand. 

The estimate of ca. 5,000 Montserrat orioles 

equates to a breeding population of ca. 1,000 pairs 

(based on known breeding success during 2004, and 

estimates of the number of immatures and floaters in the 

population). Other work suggests that this is estimate is 

too high. A territory‐mapping exercise conducted in 

2005 suggests a population of several hundred pairs, but 

certainly well under 1000. 

The estimate for brown trembler is open to some 

doubt, because the detection curve is a relatively poor fit 

to the data, but the estimates are of a population of only

Bowden, RSPB)

a few hundred birds. Given that tremblers are almost 

entirely confined to the rainforest areas of Montserrat 

(being extremely rare in lowland dry forest), and also 

that there is some (tentative) evidence of decline since 

1997 (Dalsgaard et al., 2007), there is some concern for 

this species. Almost nothing is known of its ecology on 


6.1.4. Conservation importance of the Centre Hills 

The Centre Hills is an Important Bird Area 

(Sanders, 2006) of considerable importance to global 

conservation. It qualifies as such because it supports a 

significant assemblage of Restricted‐range Species, and 

important numbers of two Globally Threatened Species. 

Apart from being one of only two sites for the 

endemic, Critically Endangered Montserrat oriole (Fig. 

6.3), it is possibly the world headquarters of the globally 

Vulnerable forest thrush (Fig. 6.4): the species is reported 

to be uncommon and declining on St Lucia and 

Guadeloupe, with status on Dominica unclear 

(BirdLife_International, 2006), D. Wege, pers comm.) 

In keeping with the high endemicity characteristic 

of the Caribbean region, Montserrat forms part of an 

Endemic Bird Area – EBA030, the Lesser Antilles 

(Stattersfield et al., 1998). This 6,300 km 2 EBA stretches 

from Grenada in the South to Anguilla in the North, and 

has 33 Restricted‐range [bird] Species, of which 24 are 

found only within this EBA, and the remaining nine are 

found in parts of some of the neighbouring EBA’s 

(EBA029 Hispaniola, EBA028 Puerto Rico & the Virgin 

Islands, EBA026 Bahamas). 

(Stattersfield et al., 1998) report twelve Restricted 

Range Species occurring on Montserrat (Table 6.5). 

There are substantial populations of ten of these species 

in the Centre Hills. Lesser Antillean flycatcher Myiarchus 

oberi is a very rare species on Montserrat, and its status is 

unclear. It is most likely to be a non‐breeding vagrant, 

occasionally detected in lowland dry forest, and not recorded 

in the Centre Hills hitherto. Antillean euphonia 

is also very scarce and is primarily found in the fringes 

of the hills during the winter months. It has been recorded 

in the Duberry area of the Centre Hills during 

Forest Bird Monitoring work. It is not clear whether it is 

a regular breeding species in Montserrat, although we 

think this is likely (in very small numbers). For bridled 

quail‐dove, purple‐throated carib, forest thrush, brown 

trembler and Montserrat oriole, the majority of the 

Montserratian population occurs in the Centre Hills. The 

remaining five species have substantial populations elsewhere 

in Montserrat (see above). 

The two remaining IBAs on Montserrat are the 

Northern Forested Ghauts and the South Soufrière Hills. 

The former comprises discrete, small patches of lowland 

dry forest, mostly fringing the Centre Hills. The latter is 

a patch of wet and mesic forest in the exclusion zone of 

the south of the island, which is surrounded by pyroclastic 

flows. Both sites support most of the Restrictedrange 

Species that the Centre Hills holds. However, the

Northern Forested Ghauts site does not have Montserrat 

orioles, and other key species such as bridled quaildove, 

forest thrush and brown trembler are extremely 

scarce. Both sites are much smaller than the Centre Hills 

(only 100‐400 ha, compared to ca. 1,400 ha for the Centre 

Hills). It is therefore clear that the Centre Hills is by far 

the most important site for bird conservation in Montserrat, 

and has great importance in a regional and global 

context. 

6.1.5. Threats and limiting factors 

Habitat destruction 

The Restricted‐range and globally threatened 

bird species that occur in Montserrat are primarily 

threatened, not surprisingly, by habitat destruction and 

invasive alien species. The forest specialist species ‐ 

bridled quail‐dove, forest thrush, brown trembler, Antillean 

euphonia, and Montserrat oriole ‐ are most at risk 

from habitat destruction. . These are also the species 

with the smallest global ranges. However, as previously 

noted, in Montserrat, rainforest destruction has been 

slight in recent years. Dry forest is more vulnerable, because 

lying predominantly outside the Forest Reserve 

and in areas heavily impacted by human agricultural 

and urban development. Among the Restricted‐range 

Species in Montserrat, Antillean crested hummingbird, 

forest thrush, scaly‐breasted thrasher, Lesser Antillean 

bullfinch and possibly Antillean euphonia can be considered 

dry forest specialists. However, the first three of 

these are also found relatively frequently in other forest 

types, and the bullfinch is common in humandominated 

areas. 

Degraded dry forest areas are relatively widespread 

in lowland Montserrat, but only a relatively 

small area of dry forest is contiguous with the main Centre 

Hills forest block, predominantly in the north‐east of 

the island. Thus isolation and edge‐effects are likely to 

be most severe for dry forest bird populations. 

Invasive Alien Animals and opportunistic omnivores 

Lesser Antillean endemic birds are perhaps not 

as sensitive to introduced predatory mammals as species 

of islands such in the Pacific Ocean, because terrestrial 

predators were already present, in the form of various 

_______________________________________________________________________________________________________________________ 


108

eptile and amphibian species, prior to human introduction 

of rats, cats and mongooses. Nevertheless, the impacts 

of introduced species on Lesser Antillean landbirds 

are not well studied, and anecdotal information 

suggests that they may have been under‐estimated in 

the past. As noted above, both black (ship) rats Rattus 

rattus and brown (Norway) rats R norvegicus are abundant 

in the Centre Hills, and might be expected to reduce 

tree regeneration, and macro‐invertebrate and 

small herptile abundance (Allen et al., 1994; Wilson et al., 

2003; Towns et al., 2006). If this does occur in Montserrat, 

the effects on forest bird species might be considerable, 

for example by reducing food availability and changing 

habitat structure. An experiment is currently under way 

to investigate such effects. Research work during 2001‐5 

has shown that rats (apparently mostly R rattus) are major 

predators of Montserrat oriole nests, and also predate 

forest thrush nests (G.A.L. Gray pers comm.). Population 

models show that rat predation is sufficient to drive 

a decline in the Montserrat oriole population in the Centre 

Hills in some years. There is no information on 

whether other bird species are similarly affected. 

As noted above, feral cats are also probably present 

in the Centre Hills, with unknown impacts on forest 

birds. The high abundance of opportunistic omnivores is 

a potential concern for the avifauna. Both as competitors 

and predators, rats and thrashers can have important 

detrimental effects on the avifauna. They are notable 

predators of birds nests, and major consumers of large 

invertebrates (Arendt, 2006; Towns et al., 2006). 

Catastrophic disturbance 

The impacts of hurricanes on West Indian avifaunas 

have been well‐studied in recent years (Wiley and 

Wunderle, 1994). In general, effects have been relatively 

short‐term; it is often difficult to tell whether observed 

declines in some populations reflect mortality or redistribution 

to less affected areas. Most severe impacts are 

thought to occur due to food shortage after the storm – 

affecting nectarivores and frugivores above all – rather 

than due to direct impacts of the storm itself. There is 

evidence of inter‐site and inter‐habitat movements by 

some populations in response to hurricane damage. 

Hurricane Hugo, one of the most powerful storms in 

history, passed directly over Montserrat in October 1989, 

with massive impacts on human society. There were also 

enormous ecological effects, with defoliation of forests, 

and substantial tree‐fall. Bird survey work in March 

1990, with comparisons to earlier work by the same observer 

in 1984, suggested that the avifauna had suffered 

relatively minor and short‐lived impacts (Arendt, 1990). 

There was a suggestion that the steeply incised valleys 

of the hill ranges had served as refugia where defoliation 

was less severe. The effects of the volcanic eruption 

on the avifauna are summarised above. 

Catastrophic natural events, while a natural feature 

of Caribbean islands, are also a major risk to the 

avifauna. If more than one negative factor (unusual precipitation, 

hurricanes and eruptions) occurs close together 

in time, then populations with limited ranges are 

clearly vulnerable to extinction, whether these events are 

natural or not. Population modelling indicates that such 

events in combination are likely to greatly increase extinction 

risk for Montserrat oriole, and the 1997‐2002 

decrease in the oriole population seems to have resulted 

from a combination of ash‐falls and dry season drought, 

plus high numbers of nest predators. 

Precipitation 

Analysis of forest bird monitoring data indicates 

that rainfall is an important determinant of bird population 

trends, though exact patterns are currently hard to 

determine (Dalsgaard et al., 2007). Detailed studies of 

Montserrat oriole support this. In general, reproductive 

output of orioles is low in years when the dry season 

(which coincides broadly with the breeding season) is 

relatively dry (unpublished data). This is a consequence 

of both reduced reproductive investment (laying frequency, 

clutch size) and increased nest failure rates, particularly 

due to predation. Such a response may not be 

common to all species: Montserrat oriole is one of rather 

few species to strongly avoid dry forest areas, so clearly 

does not tolerate drought‐prone areas well. There is also 

evidence that adult survival of orioles is lower when the 

wet season is relatively wet (unpublished data). This 

may, speculatively, result from reduced arthropod availability 

in cool, wet and windy periods during winter. 

Recent research in other West Indian islands supports 

the idea that weather patterns have important influences 

on bird population trends (Dugger et al., 2004). 

Clearly, variability in weather is a natural phenomenon, 

and as such would not normally be considered 

a threat to conservation interests. However, if it is 

true that it is a major driver of population trends, then it 

is clearly important to monitor weather and be aware of 

likely consequences of droughts and wet periods. Furthermore, 

anthropogenic climate change will cause directional 

shifts in temperature and precipitation patterns 

during the present century, outside the range of current 

variations, and hence might cause major changes in bird 

abundance. 

Threats – Conclusions 

This section on threats to the birds of the Centre 

Hills needs to be set in context: over ten years of bird 

monitoring, all forest bird species have been stable or 

increasing, despite some shorter‐term declines, that appeared, 

in the case of the oriole 1997‐2002, extremely 

worrying (see below). The possible exception to this, 

though data are scant due to its rarity, is the brown 

trembler. Thus, it seems that, in recent years, the threats 

described have not been sufficient to drive population 

declines in Montserrat’s forest birds. 

Nevertheless, there is much to be concerned 

about. First, Montserrat’s forest birds have lost approximately 

60% of their habitat during the volcanic eruptions. 

There has been further small‐scale loss of small 

_______________________________________________________________________________________________________________________ 

109 


and peripheral forest areas in the north, as the area has 

been re‐developed. Therefore, the Centre Hills are increasingly 

the sole location for many species. Second, 

although invasive alien species and the very high 

pearly‐eyed thrasher densities don’t appear to be driving 

ongoing declines in forest birds, we do not know to 

what extent populations are limited by these factors; that 

is, forest bird populations may be stable, but at substantially 

lower levels than would be seen in the absence of 

aliens. Third, climatic threats will worsen dramatically 

in future years, due to anthropogenic climate change. 

Fourth, changing climate might increase the impact of 

invasive alien species. For instance, increased frequency 

or force of hurricanes might create more short‐term 

habitat destruction, but also the higher levels of disturbance 

might favour invasive alien plants over native 

species. As climate moves out of the range experienced 

on Montserrat in the past, native species may be increasingly 

stressed, and therefore be increasingly sensitive to 

competition and predation by invasive alien species. 

Finally, some invasive species are still in an increasing 

phase – most notably pigs, with their enormous destructive 

potential, and perhaps some plant species. 

6.2 Patterns in bird diversity within the Centre 


6.2.1. Altitudinal variation in species abundance 

The Centre Hills continuous forest block runs 

from almost sea level in the north‐east of the island to 

around 740 m asl on the summit of Katy Hill, and comprises 

a transition from dry forest, through mesic and 

wet forest to elfin forest: altitude is the key environmental 

gradient in the site. 

The Centre Hills Forest Bird Monitoring Programme 

provides quantitative data from points distributed 

between ca.50‐740 m asl, and in all major habitat 

types, and thus gives good information on altitudinal 

distribution of bird species (Fig 6.5). Among forest bird 

species, there are several which appear to be most frequent 

in dry forest: mangrove cuckoo, scaly‐naped pigeon, 

Caribbean elaenia, forest thrush, scaly‐breasted 

thrasher and Lesser Antillean bullfinch all show a general 

decline in abundance with increasing altitude. The 

effect is particularly marked for mangrove cuckoo and 

Lesser Antillean bullfinch. A second group of species 

reach peak abundance in mesic and wet forest at intermediate 

altitudes: bridled quail‐dove, brown trembler 

and pearly‐eyed thrasher reach peak abundance at 

around 350 m, in the mesic forest zone, while purplethroated 

carib and Montserrat oriole peak at 500 m, 

where mesic forest grades into wet forest. Among these, 

Montserrat oriole shows a particularly pronounced pattern, 

being effectively absent from dry forest, while bridled 

quail‐dove is almost absent from high altitude sites. 

Antillean crested hummingbird shows a curious and not 

very pronounced pattern, which we do not fully understand, 

of reaching peak abundance in dry and wet‐elfin 

forest, with lower abundance at intermediate altitudes. 

Bananaquit, somewhat surprisingly, becomes more 

abundant with increasing altitude. 

Overall species richness tends to decrease with 

increasing altitude in the Centre Hills (Fig 6.5). However, 

this trend masks a different pattern among more 

specialist forest bird species and among Restricted‐range 

Species, which are generally of greatest conservation 

concern. Among these groups, species richness increases 

with increasing altitude up to around 350 m asl, and 

decreases again at greater altitudes. 

The conclusion to be drawn from these varied 

altitudinal distribution patterns among species and species‐groups 

is that the conservation value of the Centre 

Hills can be maximised by conserving the full range of 

elevations in a single continuous forest block. This is the 

only way to capture the different altitudinal preferences 

of the full range of species. Given the comments made 

elsewhere about the relatively small area of dry forest, 

the greater threats it faces and its more fragmented state 

outside the forest reserve, maintaining an area of dry 

forest continuous with the higher elevation forest currently 

contained with the forest reserve is vital. 

Curves are based on Generalised Linear Models, 

using altitude as a covariate, year as a categorical effect, 

and point x season as a repeated‐measures effect. Linear 

and quadratic altitudinal effects were tested, and the 

best fit model (using Maximum Likelihood) was used. 

For more abundant species, the response variable was 

bird counts, with a Poisson distribution and log‐link 

function; for less abundant species, bird presenceabsence 

was the response variable, with a binomial distribution 

and logit link function. For species groups, the 

response variable was number of species, with a negative 

binomial distribution and log‐link function. 

6.2.2. Spatial patterns in the Centre Hills avifauna 

Figs 6.6 – 6.10 illustrate some spatial patterns in 

bird richness and abundance, based on an Inverse Distance 

Weighted interpolation of the 1997 and 2004 census 

data. The maps need to be interpreted with some 

caution. Each census comprised a single 10‐min pointcount 

in each location, so there is a considerable degree 

of stochasticity in the counts; apparent hotspots can be 

driven by random chance to some extent. Furthermore, 

each census lasted for approximately two weeks, during 

which weather conditions varied substantially. Certain 

parts of the hills were done on days when the weather 

was relatively poor for detecting birds, which can generate 

spurious spatial patterns. Finally, the interpolations 

are based purely on the count data; they take no account 

of topography or other environmental variables, which, 

in the steep hills of Montserrat can vary over very small 

areas, and which we have shown are important determinants 

of bird abundance. 

In both 1997 and 2004, Montserrat orioles had a 

number of localised and widely scattered hotspots, and 

were scarce across most of the Centre Hills (Fig 6.6a‐c).

There was almost no concordance between the hotspots 

in 1997 and 2004. This may reflect rapid turnover of local 

hotspots, due to stochastic factors or ephemerally suitable 

habitats; however, it may equally reflect a considerable 

degree of stochasticity in the point‐counts themselves, 

see above. There was evidence of a systematic 

shift in the oriole population between the two censuses. 

In 1997, the species appeared to be patchily distributed 

throughout the hills with one large area of higher density 

in the central zone, running west‐east from the head 

of Hope Ghaut to the Bugby Hole/Corbett Spring area. 

In 2004 there was a strong overall bias towards the eastern 

flanks. The change map shows a strong pattern of 

declines in the west, and increases in the east. 

Forest thrushes are largely concentrated around 

the edges of the Centre Hills, with hotspots in particular 

in the south‐west, north‐west and east (Fig 6.7a‐c). This 

pattern did not change between censuses in 1997 and 

2004, although the location of individual hotspots did, 

and probably reflects the species’ preference for lower 

altitude forests. The change map for forest thrush shows 

a general increase in population density across most 

areas, but little spatial pattern. 

The maps for bird species richness and Restricted‐range 

Species richness are very similar in their 

respective years, which largely reflects the fact that the 

majority of birds in the forest are of restricted‐range (Fig 

6.9a‐c, Fig 6.10a‐c). The patterns for the 1997 and 2004 

censuses are broadly similar, with hotspots dotted along 

the western flanks, and in a broad swathe across the 

south‐eastern half of the hills, and lower richness in the 

north. The change maps suggest declines across much of 

the north and parts of the west between 1997 and 2004, 

but increases over the greater part of the hills. 

Taking all the single species maps and the richness 

maps, there is an intriguing overall pattern of increases 

in the eastern and south‐eastern parts of the hills, 

and decreases in the west/north‐west. The increases generally 

outweigh the decreases. Forest regeneration has 

taken place in parts of the eastern Centre Hills in the last 

two decades, following the abandonment of agricultural 

land, and this may be a cause of increases in the east. 

However, this does not easily account for concomitant 

decreases in the west, and these remain unexplained. 

One might tentatively suggest that greater human presence 

around the western and northern forest fringes in 

recent years could lead to increased densities of opportunistic 

omnivores, especially rats and thrashers, which 

could in turn affect other bird species, but there is no 

direct evidence for this, and the stochastic nature of 

these data must be emphasised. 

The maps illustrate an important point about bird 

distributions in the Centre Hills: that a number of key 

areas lie outside or right at the edge of the forest feserve. 

As a result of their preference for the lower altitude 

fringes of the hills, important forest thrush hotspots lie 

outside the boundary in the north, south‐west and 

south‐east. The brown trembler, like the forest thrush, 

appears to be concentrated around the forest edge, but 

unlike the thrush, their hotspots lie mainly just within 

the forest reserve. This reflects their preference for midaltitude 

forests (Fig 6.8), which tend to lie just within the 

forest feserve boundary. The oriole, with it’s preference 

for higher altitudes still, is found predominantly within 

the reserve boundary, but some occupied areas do fall 

outside. Areas with above average richness of restrictedrange 

species occur outside the reserve boundary in several 

places in both censuses, including some notable 

hotspots. This pattern has obvious implications for management. 

Hotspots outside the boundary are effectively 

unprotected, while hotspots adjacent to the boundary 

have minimal buffering against adverse impacts of human 

activities on the other side. 

6.2.3. Temporal trends in bird abundance in the 


The Centre Hills Forest Bird Monitoring Programme 

allows an insight into population trends since 

1997 (see Dalsgaard et al., 2007). Such a long run of 

monitoring data is unique among the fauna and flora of 

Montserrat, and indeed is very rare for birds in the West 

Indies. 

There is a considerable concordance in population 

trends among bird species in the Centre Hills, suggesting 

that similar environmental drivers have tended 

to influence them. The most common pattern was for an 

increase between 1997 and 2001, and a subsequent decrease 

between 2001 and 2003 (Fig. 6.11). After 2003, the 

consistency in pattern breaks down, and population 

trends were very varied. The main exceptions to this 

general pattern were Caribbean elaenia and Montserrat 

oriole, which decreased between 1997 and 2001; bananaquit, 

which showed very little change until a sharp 

drop between 2002 and 2004, and purple‐throated carib 

and Caribbean elaenia which doubled in abundance 

between 2001 and 2003 while nearly all other species 

were decreasing dramatically. 

The overall conclusion is that almost none of the 

species showed an overall decline between 1997 and 

2006. The possible exception to this is brown trembler. 

The graph for this species suggests an ongoing downward 

trend, but statistical power to confirm this is weak, 

because detection rate is low. Nevertheless, forest rangers 

concur with the idea that this species has become less 

common, and as a forest specialist Restricted‐range Species, 

it deserves careful attention. Several species are far 

more abundant in 2005 than at the beginning of the 

monitoring scheme – most notably scaly‐naped pigeon, 

bridled quail‐dove, forest thrush and scaly‐breasted 

thrasher. Unfortunately, it is rather difficult to put these 

changes into a broader context. Monitoring began at the 

height of the volcanic activity. We do not know if populations 

at that point were depleted by the intense ashfalls 

of the previous year, or indeed by other entirely separate 

environmental factors such as precipitation (see above).

Box 5 The Centre Hills Forest Bird Monitoring Programme 

Field Methods 

Post‐volcano ornithological work on Montserrat commenced with a bird census in the Centre Hills during 

December 1997 (Arendt et al., 1999). This initial count had the aim of establishing whether and where there remained a 

viable population of Montserrat oriole, and determining the abundance of other forest species following the intense 

volcanic activity of the preceding year. This census indicated that orioles were still widespread in the Centre Hills, with 

a population estimate of ca. 4,000 birds (post‐breeding population), so concern for the species’ immediate future was 

reduced. Following this successful survey, an ongoing monitoring scheme was established, based on counting a sub‐set 

of the census points on a quarterly basis. This programme continues to the present, and has now generated a decade of 

monitoring data. From informal beginnings during the peak of the volcanic crisis, it has become one of the strongest 

bird monitoring schemes in the West Indies, and is used as a template for other programmes. 

All the monitoring work is based on stationary point‐counts. Line transects are not possible in the Centre Hills, 

because the lack of paths, steep terrain and dense vegetation prevents easy, quiet movement. At each point, there is a 3‐ 

min ‘settling down’ period, to allow bird activity to return to normal following the arrival of the observers. 

Subsequently, there is a 10‐min counting period, during which all birds detected are recorded. As a means of 

generating extra detections of Montserrat orioles, we initially deployed tape‐playback of oriole song for two‐minutes 

after the end of the count, and separately recorded orioles detected during that period. However, this practice was 

discarded, as it caused a major analytical problem. Naïve orioles respond strongly to playback, and so many detections 

were made by this method in the early census visits. However, as individual orioles became accustomed to people and 

the playback, their response rapidly diminished. Hence, a decline in detections occurred, independent of population 

trends (Hilton et al., 2003). This makes accurate assessment of population trends very difficult. 

The ‘full census’ conducted in 1997 was based on 149 points, set out on a systematic grid across the whole 

Centre Hills. This has been repeated in December 1999 and December 2004. The ongoing monitoring programme was 

based on an informally selected subset of 47 of these points. During 2006, the programme was revised, with the 

frequency of counts being reduced to once per year, in March, and the number of points increased to 90, giving 

coverage of all areas and altitudes of the Centre Hills. The original census was completed by staff from the Montserrat 

Department of Environment, with colleagues from RSPB and the International Institute of Tropical Forestry, Puerto 

Rico. The ongoing monitoring programme has always been executed by Forestry staff, but with data entered, stored 

and analysed at RSPB. In order to increase the local use of the scheme’s results, the programme was re‐launched in 2006 

as the ‘’Centre Hills Forest Bird Monitoring Programme’. The data are now entered and held in the Department of 

Environment, in a custom‐built database. The next step, currently under way, is to combine the monitoring data with 

spatial information, allowing improved management of the Centre Hills. 

The aim of the monitoring programme, as with all such, is to complete the essential feedback loop that permits 

adaptive conservation management. It allows deterioration in the status of any species or area to be detected 

quantitatively, thus triggering research to diagnose the problem. Once conservation measures have been identified, 

tested and deployed, the ongoing monitoring permits their success to be assessed. Data from the scheme have been 

used to assist global prioritisation exercises. For several of the West Indies’ Restricted‐range Species, Montserrat is the 

only nation able to supply IUCN/BirdLife with quantitative trends information for Red Listing. The monitoring 

programme proved its worth when an unexpected decline in the Montserrat oriole was detected in 2000/1. Since the 

1997 census had revealed an unexpectedly large population, and volcanic activity had subsequently declined, there was 

a general expectation that the oriole was safe. However, monitoring data indicated a rapid decline, which was not 

mirrored by other species in the forest. A major research programme (‘Emergency Conservation of the Montserrat 

oriole’), funded by the UK Foreign & Commonwealth Office, began in 2001, to determine the causes of the decline. 

These turned out to be a combination of high nest predation by rats and thrashers, dry season drought in 2001, and 

ashfalls in 1998 and 2001. 

Some further quantitative census data are available for Montserrat. Since December 1997, a parallel point‐count 

census programme, covering 43 points, has been undertaken in various forested ghauts in the north of Montserrat. 

Some of these dry forest patches form a ring around the Centre Hills, with a few being continuous with the main forest 

block. Others are in and around the Silver Hills in the far north of Montserrat. The census work has generally been 

undertaken with the same frequency as the Centre Hills monitoring. A very small number of point‐counts were 

undertaken in the surviving forest patch in the South Soufrière Hills during summer 2001 and 2002, giving a small 

amount of comparable quantitative data from this, the only other surviving patch of mesic and wet forest in 


Distance-sampling to estimate absolute abundances 

Distance‐sampling (Buckland et al., 1993) was used to estimate absolute densities of the more frequently 

detected birds in the Centre Hills. Data used in this report were from a full census of 146 points, conducted between 30

Box 5 The Centre Hills Forest Bird Monitoring Programme 

Nov – 14 Dec 2004, according to standard Montserrat bird census methods (see (Arendt et al., 1999). Data were analysed 

for bird species for which we had 20 or more detections (except for brown trembler, for which a model was developed 

based on 19 detections). All detections of birds or clusters of birds were assigned to one of five distance bands: (0‐5 m, 

5‐10 m, 10‐20 m, 20‐40 m, >40 m). Distance software (v.5.0) was used to analyse data. A priori we chose three data filters: 

firstly, with all data included, in their original distance bands; secondly, with the data truncated at 40 m (i.e. data from 

the outermost distance band were omitted); thirdly, with data from the two innermost distance bands pooled into a 

single band (0‐10 m). We selected the best of these data filters based on the Chi‐squared Goodness of Fit of the data to 

the modelled detection curves, and also on whether the modelled detection curve met the assumptions of distancesampling, 

specifically, whether the modelled detectability at zero distance approximated 1. Following (Buckland et al., 

1993), we examined, for each of the three data‐filters, the following four combinations of key functions and series 

expansions: uniform‐cosine, uniform‐simple polynomial, hazard‐cosine, half‐normal‐hermite polynomial, and chose 

the model with the lowest AIC value. Distance v5.0 automatically fits the optimum number of adjustment parameters 

for each detection curve. We did not use model averaging. Empirical variance estimates were used. 

Analysing population trends 

Information about trends in Centre Hills bird species was generated using Generalised Estimating Equations 

(GEE’s), with count or presence/absence of the species concerned as a response variable (Dalsgaard et al., 2007). The 

data used were just the data from those 47 points included in the frequent censuses; data from those points that were 

visited only during the three full censuses were not included. 

All modelling was conducted using PROC GENMOD in SAS v.9.1. Counts for each species were modelled as 

Poisson distributed count data (with rescaling using the DSCALE function), with a log link function. Where data were 

underdispersed in the Poisson model, we reverted to a binomial model (presence/absence), with a logit link function. 

To accommodate the multiple counts from each point (up to n=24 counts per point), we declared ‘point’ x ‘season’ as a 

repeated measures effect with a first‐order autoregressive covariance structure, there being four separate ‘seasons’ in 

which censuses took place (Dec/Jan, Mar/Apr, Jun/Jul and Sep/Oct). We used ‘year’ (n=8 years) as a categorical 

explanatory variable, the parameter estimates for each being used as the population index values. ‘Year’ was numbered 

from the Jun/Jul census in calendar yeart to the Mar/Apr census in calendar yeart+1. 

Analysing altitudinal preferences 

As for analysis of population trends, tests of altitudinal preference of forest bird species and species groups 

were conducted using GEE’s in SAS v9.1, with count or presence/absence as a Poisson‐ or binomially‐distributed 

response variable respectively, depending on the abundance of the species. 

We used data from all point‐counts conducted during 1997‐2005. As with population trends models, we 

declared ‘year’ as a categorical explanatory variable, and ‘point’ x ‘season’ as a repeated‐measures effect. We used 

‘altitude’ as a linear and quadratic covariate, and selected the model with the best fit to the data, using Maximum 

Likelihood. 

Altitudinal data were taken from altimeter readings taken during the December 2004 full census. Because 

comparison with GIS Digital Elevation Models (DEM) indicated a systematic under‐estimate, we added 35 m to all 

values. Where 2004 altimeter readings were not available, we took the 1999 altimeter reading (to which 35 m was 

added, there being no consistent difference between 1999 and 2004 altimeter readings, and the same instruments 

having been used in both censuses). This gave very few (n =7 points) large (>50m) anomalies between DEM and 

(adjusted) altimeter readings. Among these seven points, the 1999 and 2004 altimeter readings were in good agreement 

(differing by


Bird census and study in Montserrat has been an 

impressive collective effort over a decade, creating one 

of the Caribbean’s leading long‐term monitoring 

schemes. The programme has been led by the Montserrat 

Forestry Division – now contained within the Department 

of the Environment (DoE) ‐ with support from the 

Royal Society for the Protection of Birds (RSPB), and 

several other individuals. Ken Smith (RSPB), Gerard 

Gray (DoE) and John Hartley (Durrell Wildlife) planned 

the original 1997 bird census, and Gerard Gray, David 

Gibbons (RSPB) and Wayne Arendt (International Institute 

of Tropical Forestry) instigated and designed the 

long‐term programme. The Montserrat forest rangers 

have been the core data collectors throughout, and great 

credit is due to James Daley, James Boatswain, Lloyd 

Martin, Lloyd Aymer, Calvin Fenton, Jervain 

Greenaway and John Martin for rigorous data collection 

in often difficult conditions. Several RSPB staff, volunteers 

and students have also participated in data collection, 

discussion and analysis, notably Sarah Sanders, 

Phil Atkinson, Chris Bowden, Liz Mackley, Joah Madden, 

Mark Hulme, Richard Allcorn, Bo Dalsgaard, Matthew 

Brierley, Jo Wright, Glen Tyler and Mark O’Brien. 

Dyonne Duberry (DoE) and Ian Fisher (RSPB) have led 

on data management for the project. The Montserrat 

National Trust has provided strong support to the programme, 

and staff member Philemon Murrain has been 

involved in fieldwork since the beginning. The Centre 

Hills Project staff, Carole McCauley and Stephen Mendes, 

and Ministry of Agriculture, Lands, Housing and 

The Environment staff Tony Hill and Claude Gerald 

provided valuable logistical support. David Buckingham, 

Richard Bradbury, Paul Donald (RSPB), Richard 

Young (Durrell) and Preben Blæsild (University of Aarhus) 

have all provided statistical advice. We are very 

grateful to John and Bridget Beattie for providing fantastic 

accommodation for staff visiting Montserrat. The bird 

monitoring programme has been financially supported 

at various times by the American Bird Conservancy, UK 

Environment Fund for Overseas Territories and the UK 

Darwin Initiative, as well as by the implementing institutions.

7. Bats of the Centre Hills and Montserrat 

S. C. Pedersen, R. P. Young, M. N. Morton and W. Masefield 

7.1. Diversity and status of bats in Montserrat 

Ecologically, Montserrat has a relatively simple 

chiropteran fauna of ten species including one carnivore 

(Noctilio leporinus), two predominantly nectivorous species 

(Brachyphylla cavernarum, Monophyllus plethodon), 

four frugivores (Ardops nichollsi, Artibeus jamaicensis, 

Chiroderma improvisum, Sturnira thomasi), and three insectivorous 

species (Natalus stramineus, Tadarida brasiliensis, 

Molossus molossus), representing four families — Noctilionidae, 

Phyllostomidae, Natalidae, and Molossidae. 

Together, these ten species represent the entire extant 

fauna of native mammals on the island. 

Montserrat has historically received a great deal 

of attention from bat biologists. Twelve surveys, spanning 

28 years (survey year 1978 Jones & Baker; 1984 Pierson 

et al.; 1994 Pedersen et al.; 1995 Morton & Fawcett; 

1997‐98, 2000‐2002 Pedersen et al.; 2003 Kwiecinski; 2004‐ 

05 Pedersen et al.), have established a database that includes 

nearly 2500 captures of the ten species of bats 

from 60 locations on Montserrat. Despite this effort, two 

of these species, Sturnira thomasi (Fig. 7.1) and Chiroderma 

improvisum (Fig. 7.2) remain very poorly known 

on Montserrat (and elsewhere). 

Until recently, only two individuals of C. improvisum 

had ever been caught on Montserrat; in 1978, in 

the gallery forest that once ran through the golf course, 

1km from the mouth of Belham River, and in 1984 in the 

Paradise Estate. Just three individuals of this species 

have ever been examined in Guadeloupe (Baker & 

Genoways, 1978). Previous to the CHBA, only one individual 

of S. thomasi had been caught in Montserrat; in 

1994 in the Paradise Estate (Pedersen 1996). It was subsequently 

described as a subspecies, S. thomasi vulcanensis 

(Genoways, 1998), unique to Montserrat. As a result 

of damage caused by Hurricane Hugo and the volcanic 

activity, it was suspected that both these species had 

become extinct in Montserrat. However, the continuing 

existence of these species was confirmed during the 

CHBA when an individual of each species was captured 

in July 2005 (see below for more information). C. improvisum 

and S. thomasi are thought to be extremely rare 

and are classified by the IUCN as Endangered 

(Chiroptera Specialist Group, 1996b, d). 

Due to their vagility, bats in the Lesser Antilles 

tend to have relatively low levels of endemicity compared 

with other taxa such as reptiles and amphibians. 

However, Montserrat supports three restricted range 

species. S. thomasi vulcanensis is only known from the 

island (S. thomasi at species level occurs on Montserrat 

and Guadeloupe), C. improvisum is only recorded from 

Guadeloupe and Montserrat, while Ardops nichollsi is 

restricted to the northern Lesser Antilles (M. plethodon 

and B. cavernarum only occur on a few islands outside

Masefield, Durrell)

the Eastern Caribbean). The bat fauna on Montserrat 

can be considered of high conservation importance as it 

contains two Endangered species, as well as three Near 

Threatened species (Chiroptera Specialist Group 1996ae) 

(see Table 7.2). All of the 10 Montserrat species have 

been caught within or in the immediate vicinity of the

Centre Hills forest and therefore can be considered to 

use this site to some extent. The recently caught individuals 

of S. thomasi vulcanensis and C. improvisum were 

both captured in the Centre Hills, which therefore currently 

represents the only recorded home for these species 

on Montserrat since the volcanic eruption. 

Bats are the only extant native mammals in the 

Lesser Antilles and play a number of key ecological roles 

in ecosystems, particularly in seed dispersal and pollination, 

and are likely to be vital to the functioning of the 

Centre Hills forest. Many fruit bats carry fruit and seeds 

further away from the parent plants than bird species 

and so are of particular importance in forest regeneration. 

The dispersal of seeds plays an important role in 

the replanting of damaged forests or deforested areas 

(through volcanoes, hurricanes, clearance for agriculture, 

etc) and for some trees, bats are the main agents by 

which new areas can be reforested. Fruit production 

requires pollination of the flowers on the plant/tree in 

question and many bats feed on flowers and nectar, and 

in doing so transfer pollen between plants. Many trees 

that are of economical importance to man are pollinated 

by bats, i.e., calabash, mango, banana, and cashew. 

Many insectivorous bats eat huge numbers of insects 

nightly. For example, a small colony of free‐tailed bats 

can consume tens of thousands of mosquitoes in an area 

each evening, which represents free pest‐control for humans 

living nearby. Bats are sometimes considered 

ʺkeystone speciesʺ (after the keystone that symbolically 

holds up an entire building) because the loss of bats 

from an ecosystem may set‐off a devastating cascade of 

effects throughout an ecosystem. For example, some 

trees may depend entirely on bats for pollination; if bats

Data from Findley, 1993 

are lost from the ecosystem, so are the trees and all their 

dependent species. 

The number of species found on an island tends 

to be correlated with the size (area) of the island, the 

distance from a source (typically a continental area) and 

the diversity of habitats available, which in most cases is 

directly related to elevation of the island. Increased elevation 

usually results in increased rainfall and more 

diverse vegetation (MacArthur et al., 1972). Morgan and 

Woods (1986) found that 69% of the variance in West 

Indian mammalian faunal diversity could be explained 

by island area alone while the ʺremaining 31% of the 

variance must be dependent upon other variables such 

as habitat diversity and distance from source areas.” 

Following models that have been applied to amphibians 

and reptiles (Preston, 1962), birds (Hamilton et al., 1964), 

and West Indian bats or mammalian fauna (Morgan and 

Woods, 1986; Griffiths and Klingener, 1988), a speciesarea 

curve for the Antillean bat fauna was constructed 

(Fig. 7.3). 

The relative position of an island ʹabove the curveʹ 

may be attributed to (1) a long history of survey efforts; 

(2) a wealth of sufficiently diverse habitat that supports 

a high level of bat species richness; and (3) close proximity 

to source islands. Conversely, the relative position 

of an island ʹbelow the curveʹ may be attributed to (1) a 

simple case of under‐sampling; (2) a dearth of sufficient 

habitat to support bat diversity; and (3) the presence of 

an insurmountable biological barrier beyond which bats 

cannot move. The primary forcing agent behind the 

inter‐island movement of bats is probably by way of 

tropical storms (S. Pedersen, unpubl. data). Several islands 

with low biodiversity (e.g., Antigua, Barbuda, St. 

Maarten) may simply be so unfortunate as to not lie 

downwind from a large source island. 

Montserrat, with its 10 species of bat, is positioned 

well above the regression‐line in Fig. 7.3 relative 

to other islands of similar size due mainly due to the 

presence of two very rare species (S. thomasi, C. improvisum). 

We explain this as being due to Montserratʹs 

_______________________________________________________________________________________________________________________

down‐wind location and close proximity (55 kilometres) 

to Guadeloupe (12 species; Baker et al., 1978; Genoways 

& Baker, 1975; Genoways & Jones, 1975; Masson & 

Breuil, 1992), high elevation and topographic diversity, 

and the fact that the island remains relatively underdeveloped 

in terms of tourism. If this observation is correct 

and we can compare Guadeloupe and Montserrat 

bat faunas, it is interesting to note that two species of 

insectivorous bat (Myotis nigricans, Eptesicus guadeloupensis) 

remain ʺmissingʺ from Montserrat despite extensive 

survey efforts over 28 years. It is unclear whether there 

is something unique about these two bats that makes 

them less likely to disperse. 

Due to their mobility and nocturnal activity patterns, 

estimating the size of bat populations is very difficult. 

Given this difficulty, a simple metric (BNN ‐ bats 

captured per net‐night) has been developed to approximate 

the abundance of bat populations at our sample 

sites using mist‐netting to catch individual bats 

(Genoways et al., 2006; Pedersen et al. 1996, 2003, 2005, 

2006). Preliminary data based on night‐vision recordings 

of flyways with and without nets show that 

only 5% of the bats in an airspace ever come into contact 

with the mist‐net and then only 60% of those become 

snared by the net (Larsen et al., 2005). This suggests 

mist‐netting could vastly underestimate abundance and 

possibly species richness. However, given the large historical 

and current sampling effort on Montserrat it is 

unlikely that species richness has been substantially under‐estimated. 

Figure 7.4 shows a species accumulation 

curve for Montserrat, which reaches an asymptote in 

1994 at 10 species. 

We have utilized the BNN metric conservatively 

by avoiding its use as an estimate of population size per 

se, but rather as an approximation of bat activity at a 

particular location. However, if we compare trends in 

BNN over time from any single location, BNN can be 

viewed as a crude proxy for overall bat population 

trends. If all feeding guilds are considered, bat capture 

rates on Montserrat are second only to St. Eustatius in 

the northern Lesser Antilles and are comparable to those 

reported from mainland populations (Table 7.1; Peder‐

are listed as "out of date" (i.e. proceeding the current [2001] revision of IUCN's red list criteria). Work on Montserrat and 

other Eastern Caribbean islands (e.g. Pedersen et al., 1996, 2003, 2005, 2006) suggests that a re-assessment would result in 

the endangerment status of some of these species being revised downwards, with the probable exception of C.

sen et al., 2005). If only fruit bats are evaluated, average 

capture rates during our surveys on Montserrat are the 

highest in the northern Lesser Antilles (Table 7.1; Pedersen 

et al., 2005). 

In summary, for its size, Montserrat appears to be 

richer in species and its bat populations appear to be 

larger than those on neighbouring islands, taking into 

account differences in sampling protocols and sampling 

effort. This is probably due to the lack of habitat modification 

due to urban and rural development relative to 

other Lesser Antillean islands. However, the bat fauna 

of Montserrat has fluctuated dramatically over the last 

25 years due to the influence of several natural disasters. 

The implications of these stochastic events on long‐term 

population dynamics deserve attention, which can only 

be investigated by long‐standing monitoring programmes. 

As well as the catastrophic threats posed by 

hurricanes and volcanoes, bats on Montserrat are also 

vulnerable to a number of other factors. Deforestation 

leads to the reduction in the availability of food plants 

and roost sites for a number of species, particularly 

frugivorous bats. Caves represent important sites for 

roosting at which large numbers of bats may congregate. 

Many species have quite specific requirements for 

roosts, for example, N. stramineus seem to require very 

humid caves which prevent their delicate wing membranes 

from drying out. Mother bats congregate to give 

birth to and suckle their babies at so‐called nursery 

roosts. If these critical sites are destroyed or disturbed 

by humans, then the bat populationʹs reproductive output 

for that year could be lost or even a large proportion 

of the whole bat population on an island may be wiped 

out in a single event. No cave roosts are known in the 

Centre Hills, but invariably the forest supports a large 

number of roosting trees. Natural water bodies are important 

as they support increased densities of both insects 

and fruiting and flowering trees, as well as being 

resource for bats drinking, and therefore the modification 

of the flow of streams and rivers in the Centre Hills 

is predicted to have negative consequences for insectivorous 

and piscivorous species of bat. 

7.2. Patterns in bat diversity within the Centre 


All 10 species of bat known from Montserrat were recorded 

during the period of the CHBA, through mist 

netting both at CHBA sample points and at long‐term 

bat monitoring sites. This was the first time all 10 species 

of bat have been recorded during a single survey 

since sampling started in 1978. According to the mist 

netting data, by far the most dominant species in the 

Centre Hills was A. jamaicensis (Table 7.3). However, 

acoustic surveys suggested that Molossus molossus was 

present at the majority of sampling points and that this 

species is ubiquitous in the area, as it appears to be on 

most Eastern Caribbean islands. Far fewer captures

Table 7.3. Number of captures of bat species at the 16 

CHBA points 

were made of B. cavernarum and the restricted range 

species A. nichollsi and M. plethodon. 

The most notable captures were the individuals 

of C. improvisum and S. thomasi vulcanensis which were 

caught at the CHBA points in Corbett Spring and Bottomless 

Ghaut respectively (Fig. 7.4). Both were lactating 

females, providing important evidence of the existence 

of breeding colonies of these species. Another 

lactating S. thomasi vulcanensis individual has subsequently 

been caught in Bottomless Ghaut in 2006. It is 

very likely that C. improvisum is extremely rare in Montserrat, 

and possibly in Guadeloupe, and therefore highly 

threatened. Following the volcanic eruptions in the 

1990s, Bottomless Ghaut is now the only location in the 

world known to support S. thomasi vulcanensis, and is 

clearly a very important site. Mobs of roughly a dozen 

S. thomasi vulcanensis were observed on two occasions in 

both 2005 and 2006 in Bottomless Ghaut, which may 

suggest they are not as rare as once thought but were 

missed in previous monitoring efforts and tend to be 

hard to catch in mist‐nets. Another bat caught in Bottomless 

Ghaut during the CHBA was initially identified 

as A. nichollsi but (following discussions with G. 

Kwiecinski) it is possible this was a Stenoderma rufum. 

This species has not previously been described further 

south than the Virgin Islands but unfortunately no photographs 

were taken of this individual for retrospective 

identification; further sampling in Bottomless Ghaut is 

recommended and may prove productive. 

Three species were not recorded at the CHBA 

points but were caught at the long term monitoring sites. 

Two fishing bats (Noctilio leporinus) were caught at Sappit 

River in the Centre Hills. This was of interest as this 

species was unrecorded on Montserrat following the 

volcanic eruption until the capture of a single specimen 

in 2004 (by S. Pedersen and team). Though readily netted, 

these animals have never been captured in large 

numbers in Montserrat. The highest observed activity 

and netting success of these bats between 1978 and 2005 

was recorded in 1994 and 1995 (post‐Hugo, pre‐volcano) 

along the Belham Valley River, but this site has subse‐

quently suffered severe damage as a result of pyroclastic 

flow and ashfall. One individual was netted in a deep 

ravine at a higher elevation in Hope Springs in 1984. 

Given that the Hope springs site was 1.5 km distant 

from the nearest known foraging area, this suggested 

there was a N. leporinus roost site somewhere in this locality 

but whether it still exists is unknown. Although a 

globally widespread species, it appears restricted to 

lower elevations and may have limited habitat available 

to it on Montserrat, and other small Caribbean Islands, 

which makes Sappit River probably the most important 

site for N. leporinus on the island. T. brasiliensis was also 

caught at Sappit River and in an abandoned building in 

the village of Lees in 2005. Finally, N. stramineus, believed 

to be an obligate cave roosting species, was found 

at a roost in tarrish pits immediately south of the Centre 

Hills boundary near Happy Hill. 

The number of bat species recorded at the CHBA 

points varied across the Centre Hills (Fig. 7.5). Five species 

were caught at the Bottomless Ghaut sampling 

point, including S. thomasi vulcanensis, which therefore 

appears to be a very important ghaut for bats. Three 

species were recorded at three sampling points, including 

Gun Hill, Upper Blakes and Jackboy Hill. The latter 

two sites, Bottomless Ghaut and Corbett Spring, where 

the endangered C. improvisum was caught, all fall in the 

east and north‐east of the Centre Hills. This region 

therefore appears to be a key zone for bats in the Centre 

Hills. 

However, examination of the long term monitoring 

data (summarised in Table 7.4) reveals other important 

sites within the Centre Hills. Due to the large effort 

required to catch all bat species using a particular site, 

the monitoring data provide a more accurate estimate of 

species richness for a given area. The Sappit River, 

which is still relatively intact following the volcano, can 

be currently considered a key site for bats, with seven 

species recorded there between 1978 and 2005. The 

lower Belham Valley and Paradise Estate have suffered 

severe damage from the volcano and are currently 

unlikely to support the high species richness that has 

been recorded historically. Hope Springs, Soldier and 

Runaway Ghauts and the Lawyers area are other relatively 

undisturbed and important sites for bats in the 

Centre Hills. 

Due to their high mobility and capacity of ranging 

over wide areas, bats present a number of challenges 

to the identification of key zones and habitats within the 

Centre Hills. Further, the CHBA data only represent a 

single ‘snapshot’ of the distribution of bat species in the 

Centre Hills. The long term monitoring data tend to be 

collected between June and August and therefore may 

not be a representative sample of habitat use and movement 

of bats across an entire year. Despite these issues, 

it is clear the Centre Hills forest overall represents a vital 

resource for bats on Montserrat for foraging, roosts and 

nursery sites, particularly for the frugivorous species. It 

is noteworthy that both native and exotic fruiting trees

Table 7.4. Number of species caught and sampling effort expended between 1978 and 2004 at 11 sites within or in the 

vicinity of the Centre Hills 

are likely to be important for this guild and therefore 

removal of exotic trees may reduce food availability for 

a number of frugivorous species, including the two Endangered 

species. Offsetting this impact by planting 

native fruiting trees would need to be considered. Flowing 

and standing water bodies are a key resource for 

insectivorous and piscivorous bats and therefore water 

management practices in the Centre Hills will have implications 

for these species. 

Bats that frequent the Centre Hills also invariably 

rely on a number of resources located outside and perhaps 

far from the forest boundary. Therefore, a coherent 

conservation strategy for bats, and the services they provide 

to the Centre Hills forest, needs to include relevant 

mechanisms for protecting these resources. In particular, 

roost sites are an extremely valuable resource. Bats 

as a group use a number of different roost types such as 

caves, trees and buildings but whilst some species utilise 

a wide variety of roosts (e.g. A. jamaicensis and M. molossus) 

others seem to have more specific requirements (e.g. 

caves for N. stramineus and B. cavernarum; tree foliage for 

A. nichollsi). Volcanic activity is known to have destroyed 

a number of roost sites in the south of Montserrat. 

For example, a large roost used predominantly by B. 

cavernarum was eradicated by pyroclastic flows in 1996. 

It is absolutely critical therefore that the remaining caves 

elsewhere on the island are protected. A cave in Little 

Bay houses a large colony of 5000‐6000 individuals of B. 

cavernarum which is probably vital for this species on 

Montserrat. The potential future development of the 

nearby port facility is likely to endanger this colony. 

The tarrish pits south of Belham Valley house the only 

known roosts for N. stramineus on Montserrat and therefore 

warrant protection. However, they are currently 

endangered by the mining/gravel facilities therein, although 

apparently they still use the roost despite the 

noise and vibration. No caves providing roost sites are 

known to exist in the Centre Hills and data on other 

types of roost sites within the forest is lacking, but it 

seems highly likely that foliage and hollow tree roosts at 

least will be found inside the boundary. Water bodies 

outside of the Centre Hills boundary are also an important 

resource for bats. In particular, the Belham Valley 

River, the only known site for N. leporinus and N. stramineus, 

is a key site and warrants attention. 

Although bats on Montserrat have been the subject 

of intense field research, an investigation of the key 

feeding and roosting sites and resources is needed to 

inform the conservation management of bats. Specifically, 

a better understanding is required of the contemporary 

distribution of species across Montserrat following 

the volcanic activity, and resource use by species of 

conservation concern and biodiversity value throughout 

the entire year. Given their importance to the functioning 

of forests, monitoring of bats should be a key component 

of a management plan for the Centre Hills. We 

recommend a two‐pronged approach; sampling at long 

term sample sites established by S. Pedersen and team 

for longitudinal monitoring, combined with a more randomised 

approach (similar to the one utilised by the 

CHBA) to produce a spatially more representative sample 

of the bat fauna.

8. Rats in the Centre Hills 

R. P. Young 

8.1. Potential impact of introduced rats on 

the Centre Hills biota 

The negative effects of introduced species of rats 

(Rattus rattus, R. norvegicus and R. exulans) on indigenous 

island animal and plants have been long recognised 

and are well‐documented (see Towns, Atkinson 

and Daugherty, 2006, for a review). These effects can 

either be direct, e.g. through predation or exploitation 

competition for food, or indirect, e.g. through changing 

habitat structure leading to shifts in predator‐prey dynamics 

or access to food resources. There is increasing 

evidence that the impacts of rats are sufficiently pervasive 

to affect ecosystem structure and function and have 

far‐reaching consequences for the persistence of island 

biotas. Effects can be over relatively short time‐scales, 

e.g. effects of high predation rates by rats on small lizards, 

or over much longer periods, e.g. low recruitment 

due to seedling predation by rats preventing forest regeneration. 

Recent studies suggest that the effects of 

introduced rats on islands have probably been greatly 

under‐estimated (Towns et al. 2006). 

Fig 8.1. Black rat Rattus rattus. (Photo: G. Hilton, RSPB) 

Globally, black rats R. rattus (Fig. 8.1) have been 

demonstrably associated with the declines or extinctions 

of the largest number of indigenous vertebrate species, 

around 60 species, and are considered the most damaging 

of the introduced rats. They are arboreal and can 

predate birds’ nests, tree‐living reptiles, fruit and seeds 

and are also capable swimmers so therefore are good 

colonisers of islands. Brown rats R. norvegicus are also 

known to have major negative impacts on indigenous 

island species, albeit less wide‐ranging, but due to their 

greater body size may affect larger prey species such as 

seabirds. Both these species have been introduced onto 

Montserrat, probably with the arrival of the first Europeans 

roughly 400‐500 years ago, and now occur in many 

areas of the Centre Hills forest. In order to evaluate 

which native species in the Centre Hills may be affected 

by rats it is informative to assess which taxa have been 

shown to be vulnerable to rats elsewhere. The following 

taxonomic groups have demonstrated global vulnerability 

to black and/or brown rats (from Towns et al. 2006): 

1. Plants with fleshy fruits and/or large edible 

seeds, or heavily scented inflorescences, or dioecious 

reproductive systems, or reliant on seabird 

effects such as enriched soil or open disturbed 

ground 

2. Terrestrial flightless invertebrates, especially 

large, nocturnal and ground‐dwelling species 

3. Amphibians and reptiles that are large, nocturnal 

and ground‐dwelling, have low annual reproductive 

output and are oviparous, laying eggs in 

rookeries 

4. Diurnal ground dwelling reptiles, including some 

snakes (vulnerable to R. rattus only) 

5. Small terrestrial birds with weak flight and are 

surface or crevice nesters near ground level 

6. Small arboreal birds, especially hole nesting passerines 

and parakeets (vulnerable to R. rattus 

only) 

7. Small ground nesting birds, including wellflighted 

species 

8. Small burrowing sea‐birds (

of the Montserrat oriole (G.M. Hilton, pers. comm.) and in 

some years achieve very high densities in the Centre 

Hills resulting in high predation rates and a concomitant 

decrease in oriole annual productivity, which had longer 

term population effects in this species. None of the bat 

species on Montserrat are ground‐dwelling or groundforaging 

and so are unlikely to be directly affected by 

rats. Rats are also known to have a major impact on 

plants, through seed, fruit and seedling predation and 

affect recruitment in plant populations. Plants with 

fleshy fruits and/or large edible seeds, or heavily scented 

inflorescences are particularly vulnerable. Terrestrial 

flightless invertebrates, especially large, nocturnal and 

ground‐dwelling species, are also particularly at risk 

from rat predation. 

Black and brown rats are therefore highly likely 

to be posing a serious threat to the persistence of a large 

number of the Centre Hills taxa by exerting a range of 

direct and indirect effects, which may be sufficiently 

strong and wide‐ranging to influence the overall functioning 

of the Centre Hills ecosystem. Most worryingly, 

three Critically Endangered species, the oriole, galliwasp 

and mountain chicken possess traits that have been 

shown elsewhere to pre‐dispose them to being vulnerable 

to the effects of introduced rats. These effects may 

have already had a severe historical impact on the population 

growth rates of these species. However, no quantitative 

data exist on the distribution and abundance of 

rats in the Centre Hills and whether rats have penetrated 

the interior of the forest at the highest elevations. As 

part of the CHBA we carried out surveys to understand 

how rats are distributed across the Centre Hills and how 

their abundance varies with habitat and landscape features. 

Nevertheless, methods of reducing the impact of 

rats on the Centre Hills ecosystem should be a central 

consideration in the design of the management plan. 

8.2. Patterns and correlates of rat abundance 

within the Centre Hills: implications 

for biodiversity conservation 

In order to detect the presence of rats and to estimate 

their distribution, short pieces of wood soaked in 

vegetable oil (‘chew‐sticks’) were placed in the ground 

at CHBA points which, if rats are present, are chewed. 

The chew‐stick data demonstrate that rats occur 

throughout the Centre Hills, even in the interior of the 

forest and at the highest altitudes on top of Katy Hill 

(see Fig. 8.2). 

We estimated the relative abundance of black and 

brown rats by placing 11 independent lines of snap‐traps 

along trails and ghauts across the Centre Hills (N.B. 

trapping line is referred to as ‘sampling site’ in the 

analysis). Each trapping line consisted of 15 snap‐trap 

stations spaced 25m apart, with two traps situated on 

the ground (within 1m of each other) and two traps tied 

to branches at eye level of nearby trees. All snap‐traps 

were baited with peanut butter. Trapping rates were 

very high in the Gun Hill region (24.4 rats per 100 trap

nights), as well as Cassava Ghaut (14.0 rats per 100 trap 

nights) and Fogarthy (9.9 rats per 100 trap nights) (Table 

8.1). The high trap rate observed at Cassava Ghaut is 

concerning given the proximity of this site to Woodlands 

where the galliwasps were found and the pre‐disposed 

vulnerability of galliwasps to rat predation. The rat 

trapping data suggest that overall black rats are much 

more abundant in the Centre Hills than brown rats, although 

differences in capture probability have not been 

taken into account. 

To test the hypothesis that rats are more abundant 

in areas with higher numbers of non‐native fruiting 

trees we investigated the relationship between mean rat 

capture rate and mean number of fruiting trees at sampling 

sites (n=11). A linear regression revealed a strong 

positive relationship between these variables with the 

mean number of fruiting tress explaining 69.1% of the 

variance in rat capture rate (Fig. 8.3). However, the 

effect of one site (Gun Hill with both the highest number 

of rats and fruiting trees) on this relationship was 

stronger than expected (i.e. high leverage) and therefore 

these results should be treated with some caution. 

We also used generalised linear mixed modelling 

to investigate the relationship between the occurrence of 

rats in individual traps and the number of non‐native 

fruit trees within 10m of the trap. The effect of altitude 

at which the trap is located (rats are suspected to be 

scarcer at higher altitudes) was also included in the 

model, as well as the interaction between number of 

fruiting trees and altitude. Sampling site was entered 

into the model as a random term to take account of nonindependence 

of individual traps. 

There was a near‐significant relationship between 

the occurrence of rats at trap stations and the number of 

non‐native fruiting trees (P = 0.061) (Table 8.2). There 

was no relationship between rat occurrence and altitude, 

but there was an association between rats and the interaction 

of fruiting tree numbers and altitude (P = 0.024), 

suggesting a higher probability of catching rats at increased 

elevations with more non‐native fruiting trees. 

This is slightly contrary to expectation. However, due to 

logistical reasons it was not possible to sample at the 

highest elevations, and therefore most trapping was 

carried out lower and mid altitudes. Therefore, this interaction 

effect may not be relevant at the higher elevations 

of the Centre Hills. 

Overall, these analyses provide good evidence 

that the number of exotic fruiting trees in the Centre 

Hills forest is positively related to the abundance of rats 

in an area. Higher numbers of rats supported by plentiful 

food non‐native fruit resources will result in high 

predation pressure on indigenous plants and animals, 

which may be sustained even when native prey decline 

(i.e. inverse density dependent mortality through preda‐

duce rat abundance in key areas of biodiversity may be 

an optimal strategy. If successful, these zones could 

serve as refuges where native species would be allowed 

to achieve high productivity and survival which would 

increase the probability of long term persistence of these 

taxa. These zones should be placed at medium to high 

elevations so that brown rat abundance is low and far 

from the forest edge and agricultural areas where rat 

populations are likely to be very high. A zone of intensive 

rat control in the Woodlands area should be considered 

as part of a Species Action Plan for the Montserrat 

galliwasp. 

We recommend that introduced rats are included 

in pressure‐state‐response monitoring programme (i.e. 

rats as a pressure on the Centre Hills biodiversity) as 

part of the management plan. Such monitoring would 

serve both as an early warning device for vulnerable 

threatened species, such as the Montserrat galliwasp and 

oriole, and to quantify the impacts of any rat control 

measures on their population size. Evidence from the 

Montserrat oriole conservation project indicates that rat 

populations show large fluctuations in sizes and can 

achieve very high densities for periods of time. Testing 

and development of a sensitive but low intensity monitoring 

technique is vital; the tracking tunnel technique 

currently being developed by the Centre Hills Management 

Plan project is promising. 


Karen Varnham provided valuable expert advice 

on the design of the snap‐trapping lines and protocols 

for data collection, as well as carrying out training of key 

individuals. Will Masefield, Richard Allcorn and Lloyd 

Martin co‐ordinated the rat trapping fieldwork and collected 

much of the data. Agnieszka Ogrodowczyk led 

the rat distribution survey. Calvin Fenton, James Daley, 

James Boatswain, John Martin, Lloyd Aymer and Philemon 

Murrain all made valuable contributions to data 

collection.

Appendix 2. Species lists of the beetles, non-beetle hexapods 

and non-hexapod invertebrates of Montserrat 

M. A. Ivie, K. A. Marske, I. A. Foley & L. L. Ivie 

The beetles of Montserrat: an annotated checkllist 

Below are listed all of the beetles known to us from Montserrat, organized by family. Each has a name at the level we 

are able to assign it. Each has a code indicating the species’ distributional status (Table A), from single island endemic 

to invasive exotic. The symbol “?” associated with this ranking, indicates our lack of knowledge of a particular taxon. 

Following the distributional code is the original citation (if any) of the species from Montserrat, as well as any notes. 

This format is also followed for the sections on non‐beetle hexapods and the non‐hexapods invertebrates.

Rejected Record: Erwin and Sims 1984 recorded the very large, rare South American and Trinidadian species 

Enceladus gigas Bonelli from Montserrat, but it seems certain that this was either a mislabeled or misinterpted specimen. 

Since Montserrat is a common place name in Latin America, including a place name in Trinidad, the specimen must 

have been from a Montserrat in Trinidad or northern South America. A search for the specimen in question at the 

NMNH in 2007 did not turn up the source of the record, but at some point between 1984 and 2007, Erwin dropped the 

record from his distributional database (T. Erwin, pers. com.).

The non-beetle hexapods 

NOTE: No records for Protura, Diplura, Zoraptera, Mantodea, Embidina, Phthiraptera, Siphonaptera, and Strepsiptera 

are included, in spite of the fact that most, if not all of these Orders will be found to occur on Montserrat. All Orders 

listed below, even those without specific records, have vouchers in the WIBF collections, or have been deposited elsewhere 

as noted. 

COLLEMBOLA 

Stevens & Waldmann (2001) reported a single published record of an Isotomidae from Montserrat. However, several 

families of this group are present on Montserrat, and springtails are abundant and speciose in the soil, canopy and litter 

layers. Study of this group would yield many new species records for Montserrat.

MICROCORYPHIA 

Not reported from Montserrat by Stevens & Waldmann (2001), an unidentified species of this family was taken commonly 

in the Centre Hills. 

Meinertellidae

THYSANURA 

Not reported from Montserrat by Stevens & Waldmann (2001), an invasive member of this order was reported from 

Montserrat in 1995, and another undetermined species is very common in the Centre Hills.

The dragonflies and damselflies are widely used as indicators of environmental health. Cooter (1983) provides the only 

4 published records of this group for Montserrat, which we expand to 16. Given the sensitivity of this group to water 

conditions, we were surprised at the number which have survived the volcano’s deposits in Montserrat’s fresh water 

habitats. Two species are local endemics, both only recently discovered from Guadeloupe (Donnelly 2007).

DERMAPTERA 

Because the earwigs have been revised for the West Indies (Brindle 1971), little attention was paid to this group, and 

only 14 mounted specimens were preserved. This proved to be a mistake, as 8 species are represented, 4 of which cannot 

be identified using Brindle! Obviously, here is a place for more collecting.

THYSANOPTERA (Thrips) 

None of the species listed by Stevens & Waldman (2001) have actually been recorded from Montserrat, and no other 

records have been found, but thrips are speciose and abundant, both as plant pests (probably invasive species), and as 

native plant feeders, fungivores and predators in forest litter and canopy. Fig. P gives an idea of the diversity from a 

single canopy fogging sample.

Stevens & Waldmann (2001) recorded 6 species of ants from Montserrat. Several thousand specimens of many species 

from the WIBF have been deposited with E. O. Wilson at Harvard’s Museum for Comparative Zoology. 

NOTE: The following 6 families (Tiphiidae, Scolyidae, Pompilidae, Vespidae, Eumenidae and Sphecidae) were the subject 

of a review by Evans (1972) of material collected by the Bredin‐Archbold‐Smithsonian Biological Survey of Dominica. 

It is interesting to compare the relative numbers of species (Table C) produced with targeted collecting by wasp 

specialists and others on the much‐larger‐and‐higher island of Dominca, to those collected incidentally by coleopterists 

on Montserrat. From standard island biogeographic theory, we would expect 1.5‐2.5 times more species on Dominica 

than occur on Montserrat, with a correction for the bias of the 2 groups of collectors pushing the difference higher. 

However, Montserrat’s total for the 6 families equal those of Dominica, although the family‐by‐family totals vary. 

However, in none of the cases is Dominica’s recorded fauna as large as would be expected.

This group includes many important water‐quality indicators. Botosaneanu (1973) reported an early instar Oxyethira sp. 

(as Oxyethira by Stevens & Waldmann 2001) from Montserrat, but no adults have been reported (Botosaneanu 2002). 

He recorded a total of 360 species from the West Indies, although this number is inflated by inclusion of species from 

islands in the southern Caribbean that lie within the South American biogeographic region (Botosaneanu 2002). Flint 

and Sykora (1993) list 22 species from the Lesser Antilles, none from north of Guadeloupe. Botosaneanu (1994) added 

six more new species from Guadeloupe Seven species are now recorded from Montserrat, and given that these are 

from only a few samples, and that we did not try to collect this group, at least double that number are expected. Oliver 

Flint did the determinations.

LEPIDOPTERA 

The third of the megadiverse Orders, the vast majority of the biodiversity in this group is not in the well‐known and 

highly visible butterflies, nor even in the so‐called macromoths, but in the tiny microlepidoptera that are so understudied 

throughout the world. Many plant pests and biological control agents are included in this order. We made absolutely 

no effort to inventory this group, and our additions below are what can happen purely accidentally. 

Butterflies. Perhaps, with the mosquitoes, the best studied insect group world‐wide. Our material was highly sizebiased, 

missing entirely the smaller‐sized species. Smith et al. covered the West Indian fauna extensively. Yet, even 

with all of the work done on this group, we added 2 species of butterflies to those known from the island (Table D). 

Lack of a collection record in the Ivie et al. material should not be construed to indicate the species was absent, as we 

simply did not even try to collect any of the small species, nor anything that had to be chased down.

Moths. There are hundreds of moths on Montserrat, but aside from a few pest species, there are virtually no published 

records. Stevens & Waldmann (2001) could locate only 12 species, all pests (1 Lyonetiidae, 1 Gelichiidae, 2 Pyralidae, 8 

Noctuidae) with actual Montserrat records. To hopefully spur someone to the work on the moths of Montserrat, we 

give 2 new records of very large and beautiful moths that are recorded from the island in the scientific literature for the 

first time. 

Noctuidae. This huge family is well represented on Montserrat. The largest moth on the island, well‐known as the 

“Rat‐Bat,” belongs here (Fig. T)

Sphingidae. The very large and colorful frangipani worms that appear on ornamental and wild trees from time to time 

are our representative of this family. The adult is large, but rather dull. Several other, smaller, species are more attractive.

DIPTERA 

(Except as noted, determinations by Richard L. Hurley). The fourth and last of the megadiverse Orders, the number of 

flies in a Malaise trap sample can easily overwhelm. Montserrat, with over 130 species now recorded, can be expected 

to yield hundreds more species.

Dolichopodidae (Determinations by Richard Hurley and Justin Runyon). This family is one of the most dramatic examples 

of what remains to be discovered on Montserrat. A relatively large family of small, obscure predaceous flies, the 

dolies are often overlooked. Not a single previous record of the family for Montserrat exists. Because of the interest of 

Hurley and Runyon, we made a special effort to obtain samples of this group, and what they discovered is an amazing 

46 species from Montserrat. The group was revised for Dominica by Robinson (1975), providing a solid framework for 

evaluating the Montserrat fauna. The 46 species on Montserrat, obtained without the assistance of a Dipterist, compare 

with 113 species known from Dominica (Robinson 1975). Running the Chao1 estimator (classic option in EstimateS 

7.5.1, Colwell 2007) on the 735 specimens of the 46 species gives a mean estimate of 78 species (95% CI = 53‐176 species). 

Some species of this group are shore and beach specialists, habitats we did not sample, leaving the real expected total of 

Montserratian dolies unresolved.

Megaselia spp. ? 

Syrphidae. (Determinations by F. C. Thompson and R. L. Hurley)The flower flies are one of the few relatively speciose 

groups of insects with a comprehensive West Indian revision that records all of the specimens involved (Thompson 

1981). As such, it provides an excellent opportunity to study the discovery and accumulation of records. There are 22 

species of flower flies now known from Montserrat. Table 10 shows the relationship of Thompson’s (1981) original list, 

Stevens & Waldmann’s (2001) list, the WIBF material mounted in the early part of the project and the specimens 

mounted and labeled in 2005‐2006. The Chao 1 estimate of total species for Montserrat is 25, with a 95% confidence 

interval ranging from 22‐37 ‐‐ an amazing diversity considering that the entire Lesser Antilles have only 31 recorded 

species.

Table E. Discovery of Syrphidae on Montserrat. Thompson (1981) records 34 species from the Lesser Antilles, 10 

of which are endemic. Four of these are NOT Lesser Antillean in the biogeographic sense, occuring only in 

the Greater Antilles, including the Virgin Islands. One species (Toxomerus watsoni) was recorded from Grenada, 

but not listed as Lesser Antillean. Thus, the recorded fauna of the biogeographic Lesser Antilles is 31 

species (34-4+1). Montserrat now has 19-22 species, with a predicted total of 25.

Non-hexapod invertebrates of Montserrat 

PROTOCTISTA. We have nothing to add to the 3 medically important taxa reported by Stevens and Waldmann (2001). 

PLATYHELMINTHES. Stevens & Waldmann (2001) reported one species, the trematode agent of human bilharziasis, 

to which we add another Class for Montserrat. 

Additions to Stevens and Waldman (2001): 

TUBULARIA (Flat Worms). A land planarian, possibly of the genus Rhynchodemus, occurs in the Centre Hills (Fig. V). 

Fig. V. An unidentified land planarian. (Photo: Gerardo Garcia) 

NEMATODA (Round Worms). Stevens & Waldmann listed 3 human parasites from this group, all exotic. We discovered 

only one further record of an economically important plant‐pest nematode from Montserrat, from what must be 

hundreds more plant parasitic, animal (including insect and other invertebrate) parasitic, and free‐living species on the 

island. 

Additions to Stevens and Waldman (2001): 

Rotylenchulus reniformis Linford & Oliveira, 1940 (reniform nematode) Braithwaite (1973); 

ANNELIDA. Earthworms of the Class Oligochaeta occur on Montserrat, but none seem to have been recorded. 

ONYCHOPHORA (Onychophorans). A Peripatus has been repeatedly recorded from Montserrat (Clark 1929, Peck 

1975, Read 1988, Stevens & Waldman 2001) as both Peripatus sp and Peripatus antiguensis Bouvier, all apparently based 

on a series collected in 1924 by T. W. Savage‐English (not “J. W.”, as per Stevens & Waldmann 2001. Clark reported 

that Savage‐English reported the population “now nearly exterminated.” Whatever the correct name, after 78 years, it 

was recollected in the Centre Hills at Hope Ghaut Spring in May 2003. The group is globally sensitive, and of high conservation 

interest (New, 1995) 

MOLLUSCA. The many marine species are beyond the scope of this review. Often, marine shells end up on land because 

of their use by soldier (or hermit) crabs, but should not be confused with snail species that actually live on land 

or in fresh water. Data and determinations below were kindly provided by Gary Rosenberg and David Robinson. 

GASTROPODA (Snails and Slugs) Stevens & Waldman (2001) listed 5 species of snails from Montserrat ‐‐ 4 aquatic and 

one terrestrial species. One more aquatic species has been recorded since then (Bass 2003). Additions below include the 

terrestrial snails that made up the first 5 invertebrates reported from Montserrat (Bland 1875). Two terrestrial species 

were found among the collections of the Academy of Natural Sciences in Philadelphia (ANSP), and three species added 

from our collections, one a new record of an invasive pest (Fig. X), for a total of 14 snails and one unidentified slug (Fig. 

W). More terrestrial snail species have been sighted, and given the number of species known from St. Martin and Gua‐

deloupe, 30 or more species might be expected, with additions to the one single‐island endemic known to date. David 

Robinson of the USDA, based at the Academy of Natural Sciences in Philadelphia, is planning a much needed survey 

of the land snails of Montserrat in 2007. Land snails are often among the most sensitive of island species, and are a 

priority group for conservation monitoring.

ARANEAE (Spiders). Stevens & Waldmann (2001) listed 4 species of Montserrat spiders, to which we add 2 additional 

published records. This number represents but a drop in the bucket for what actually occurs on the island. Several 

thousand specimens, of what appeared to be a few dozen species, where sent to Norman Platnick at the American Museum 

of Natural History for eventual determination. The spiders recorded so far are:

ACARI (Mites and Ticks). Berlese samples, canopy fogging, beating vegetation, and infested insects indicated that 

there are hundreds (at least) of species of mites to be discovered on Montserrat. The variety of forms, sizes, colors (Fig. 

A3) and lifestyles make this a fascinating, but little known group. The opportunities for endemism are many. Unfortunately, 

they are beyond our expertise and efforts.

PSEUDOSCORPIONES (pseudoscorpions). We found no published records for this group, but one or more species 

were taken and more seen in the field. 

CRUSTACEA. To the list of 6 crabs and 6 freshwater shrimps in Stevens & Waldmann (2001) should be added Amphipods 

and Isopods, unidentified species of both, which occur in abundance on the island. 

The only records we found for this group are 2 Isopods.

This is a fertile field of further work, which may identify both invasive and native, if not endemic, species. 

CHILOPODA. Stevens & Waldmann (2001) found only 2 records for centipeds, both Scolopendridae, from Montserrat. 

A good variety of species of several Orders await formal identification, including members of the Scutigeromorpha and 

Geophilomorpha, both of which are well represented. 

DIPLOPODA. That no species of millipeds have been recorded from Montserrat is a surprise to anyone familiar with 

the island. Many species of several Orders occur on the island, from Polydesmidae, Polyxenidae, Julidae and Spirobolidae. 

SYMPHYLA. One or more species of these tiny and cryptic animals were seen in berlese samples from the Centre Hills.

Appendix 4. Information on invertebrate voucher specimens 

M. A. Ivie, K. A. Marske, I. A. Foley & L. L. Ivie 

Because of the level of taxonomic uncertainty 

involved in the identification of species from Montserrat, 

vouchers are critical to being able to track these records 

in the future. All records in this paper are vouchered 

with museum specimens, or by a citation from the literature, 

which themselves usually cite vouchers. The only 

exceptions are in the case of a few of the photos used to 

illustrate the non‐insect section, which were either taken 

by people not directly involved with this inventory, and 

which were not vouchered. 

Even well‐known species sometimes need to be 

re‐examined, and less‐known species are always subject 

to re‐evaluation. Undoubtedly, mistakes in identification 

have been made. Mistakes in species concepts are 

also expected. For many groups no literature exists to 

guide the delimitation of species, and we and our collaborators 

have been forced to use a best‐guess for species 

limits. It is expected that the number of times we 

have listed multiple species as one will approximately 

equal out with the number of single species we have 

split one as more than one, but only time will tell if this 

expectation holds. Vouchers are the key to determining 

this. Vouchers allow these identifications and concepts 

to be treated as testable hypotheses, subject to review 

and correction as needed. In any case, our listing represents 

our best understanding of the situation at the current 

time, and we hold sole responsibility for the errors 

that will be discovered. 

The vast majority of voucher specimens for this 

publication are in the West Indian Beetle Fauna Project 

Collection at Montana State University, Bozeman. However, 

it has been better to place all or portions of certain 

groups in other institutions, where they will be more 

accessible to researchers. These are listed below:

of Natural Sciences, Philadelphia.

The Durrell Wildlife Conservation Trust is a charity that was founded with the singular 

mission to save species from extinction. Our founder, the naturalist Gerald Durrell, 

was very clear in what he saw as the role of a zoo and what impact it could have in 

the future. This role was strongly linked to preservation of wildlife in its natural setting. 

Over the course of the last 50 years, the Trust has built up a worldwide reputation for 

its pioneering conservation techniques and the species that it has brought back 

from the brink of extinction. Currently the organisation runs projects in 18 countries 

worldwide. In all cases the Trust believes in working with local stakeholders to tackle 

threats in ways that are effective, sustainable and have the support of those that live 

in these regions. 

About the Conservation Monographs 

The Durrell Conservation Monograph series aims to publish applied research 

concerning either a single taxon or ecosystem that forms part of Durrell’s 

Conservation Programme. Each monograph provides a detailed source of 

information directly applicable to the conservation of biodiversity in the field. 

About the report 

The Centre Hills forest is the largest area of natural and semi-natural terrestrial habitat 

remaining in Montserrat, supporting an internationally important assemblage of 

plants and animals; many of which are unique to Montserrat and are considered 

globally threatened. The forest also provides a range of ecosystem services which 

are vital to Montserrat’s future. However the forest continues to be threatened by a 

number of pressures, including habitat degradation and invasive plants and animals. 

The monograph reports the findings of a systematic assessment of the plants, 

invertebrates, amphibians, reptiles, bats and birds of the Centre Hills and proposes a 

series of conservation priorities and actions. The assessment is being used to support 

the planning of a protected area, which will be soon implemented to conserve the 

Centre Hills forest and its natural resources.
