Maps of mammal diversity include the total species richness, major taxonomic Orders (Cetartiodactyla,Carnivora, Primates, Eulipotyphla, Chiroptera, Rodentia), threatened species, and small-ranged species. Species considered small-ranged are those with a geographic range size smaller than the global median (i.e., the 50% of species with the smallest ranges). Maps are based on data from the IUCN, July 2013 update.
For mammals, all of the maps have been generated at a spatial resolution of 10x10km. Maps represent native, extant species only. Tables of the mammal species included are available for download (http://biodiversitymapping.org/mammals.htm).
