Amphibians of the World (click maps to enlarge)
Maps of amphibian diversity include the total species richness, major taxonomic Orders (Anura, Caudata, Gymnophiona), 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.
All maps have been generated at a spatial resolution of 10×10km and use the Eckert IV equal-area projection. Maps represent native, extant species only. Tables of the amphibian species included are available for download here.
A zip file with higher resolution jpegs of the above maps can be downloaded here.
