Table 2. – Covariates of the distribution models and their contributions (mean values for all 129 species). Climate and altitude data have been downloaded from the Worldclim website, slope calculated from altitude with ArcGIS, vegetation indices have been downloaded from the IRI/LDEO data library and tree cover from GLCF. Minimal or maximal values showing the importance of a variable are marked in bold.
