Location map of the study sites.
Location map of the study sites in southern Chile, indicating the distribution of Fitzroya forests in Chile and Argentina. The map does not show stands located in the Central Depression near Puerto Montt due to their small area. Darker shaded areas correspond to higher altitudes in the Coastal Range and Andean Cordillera.

Aboveground woody biomass and productivity per species and plot.
Left panel: a) Aboveground woody biomass per species in all trees ≥10 cm diameter, b) proportion of the woody biomass presented in a) contributed by the different species in percentage (%) and c) woody biomass contributed by the large (trees≥10 cm DBH) and small (trees < 10 cm DBH) tree components within each plot. Right panel: d), e), f) the same as a), b) and c), respectively, but for aboveground woody productivity.

Aboveground woody biomass and productivity per species and diameter classes.
a), b), e), f) aboveground woody biomass for each of the most important species along different diameter classes in Alerce Costero and Alerce Andino plots. c), d), g), h) the same as in a), b), e), f) respectively, but for aboveground woody productivity. FC: Fitzroya cupressoides, NN: Nothofagus nitida, DW: Drimys winteri, MC: Myrceugenia chrysocarpa, SC: Saxegothaea conspicua.

Forest structure and carbon dynamics in Alerce Costero and Andino.
Diagram exemplifying the structure of the forest in the coastal (upper panel) and the Andean site (lower panel). The main species in each forest are identified, the mean values for each carbon cycle component from both plots and the productivity allocated to canopy, wood and fine roots (in %) are shown. Arrows indicate separated values for the Fitzroya stand only and the Nothofagus dominated subcanopy forests in AA. FC: Fitzroya cupressoides, NN: Nothofagus nitida, DW: Drimys winteri, LP: Laureliopsis philippiana, MC: Myrceugenia chrysocarpa, SC: Saxegothaea conspicua. AGB: aboveground biomass, NPPAG: aboveground productivity, NPP: total productivity.

Mean wood residence time for the main species in each plot. FC: Fitzroya cupressoides, NN: Nothofagus nitida, DW: Drimys winteri, MC: Myrceugenia chrysocarpa, SC: Saxegothaea conspicua.
