Map of human activity, threatened species richness, priority species richness and priority regions. Intensity of human activity based on (a) human population and (b) GDP (100 million). Categories were based on IUCN classification. (c) CR, critically endangered; (d) EN, endangered; (e) NT, near threatened; (f) VU, vulnerable. (g) Yellow grid cells indicate priority regions combined the results of both human population (HP) and GDP vs. priority species diversity. Blue polygons indicate protected areas (national nature reserves).
