Number of tree species threatened with extinction according to the IUCN Red List categories and criteria.

(a) Results of the Red List assessment conducted with all Red List criteria, based on a consideration of current threats, but excluding the potential impacts of climate change (from Tejedor Garavito et al. [28]).
(b) Number of species in each Red List category meeting the thresholds associated with criterion B1 only, using an estimate of EOO based on current distribution data, with area of unsuitable habitat subtracted (using Globcover map and altitudinal threshold).
(c) Number of species in each Red List category meeting the thresholds associated with criterion B1 only, using an estimate of EOO based on modelled potential present distribution using current climatic variables, with area of unsuitable habitat subtracted (using Globcover map and altitudinal threshold), and further limited to the minimum convex polygon based on current distribution.
(d) Number of species in each Red List category meeting the thresholds associated with criterion A3 only, using an estimate of EOO based on modelled potential distribution using climatic variables from the A2 scenario, with area of unsuitable habitat subtracted (using Globcover map and altitudinal threshold), and further limited to the minimum convex polygon based on current distribution.
(e) Number of species in each Red List category meeting the thresholds associated with criterion A3 only, using an estimate of EOO based on modelled potential distribution using climatic variables from the B2 scenario, with area of unsuitable habitat subtracted (using Globcover map and altitudinal threshold), and further limited to the minimum convex polygon based on current distribution.
(f) Number of species in each Red List category, considering both current threats and potential future climate change, and based on application of all Red List criteria. Abbreviations: CR, Critically Endangered; EN, Endangered; VU, Vulnerable; NT, Near Threatened; LC, Least Concern; DD, Data Deficient.
Note that the number of species classified as DD varied between columns according to the method used. For the first column, species were classified as DD according to the expert opinion of the network of specialists; for the second column, those listed as DD were those with fewer than three distributional points (required for MCP), and for those columns involving GAM, those species with fewer than five records were excluded from the modelling and classified as DD.
