Maps of mammal diversity in the USA include the total species richness, endemic species, threatened species, and small-ranged species. Species considered small-ranged are those with a geographic range size smaller than the median (i.e., the 50% of species with the smallest ranges) either globally or of the species in the lower 48 states. Maps are derived from digital distribution maps from the IUCN, July 2013 update.

The priorities map is described in, “U.S. protected lands mismatch biodiversity priorities,” by Clinton N. Jenkins, Kyle S. Van Houtan, Stuart L. Pimm, and Joseph O. Sexton. Published April 6, 2015, in Proceedings of the National Academy of Sciences. www.pnas.org/cgi/doi/10.1073/pnas.1418034112

Maps have been generated at a spatial resolution of 10x10km for rasters, or maintained as vector format where more appropriate, and use an Albers Equal Area Conic projection. Maps represent native, extant species only. Tables of the species included are available for download here.
