Below are estimated distribution maps for terrestrial vertebrate species across five western states including Arizona, Colorado, Nevada, New Mexico, and Utah. The maps employ animal habitat models from the Southwest Regional Gap Analysis Project at the United States Geological Survey. Some species distributions may extend beyond the five-state boundary.
