Habitat for mammals is disappearing quickly from the Earth's surface. Conservationists are in a race against time to protect remaining habitat to stem the loss of biodiversity. Critical to these conservation efforts is focusing on-the-ground actions on the places where threatened species are found. To aid conservationists in determining where these species occur, NatureServe and a consortium of conservation organizations joined forces to develop a digital library of the distributions of the mammals of the Western Hemisphere. The goal of the project was to make these maps easily accessible to conservation planners and other interested users.
The maps are fully annotated to indicate scale, sources, taxonomic decisions, and such issues as historic versus current ranges, origin (native or introduced) and island distributions, where applicable.
These maps are presented as a free resource for conservationists, researchers, and the general public. To view the map for each species, visit our NatureServe Explorer website, search for the species you are interested in, and click on "Range Map." The map files can be viewed using ESRI ArcExplorer software, which can be downloaded for free from ESRI's website. Please contact ESRI, not NatureServe, for any support needs related to the software.
