GAP Species Viewer


The Gap Analysis Program's (GAP) Species Viewer allows users to explore, download, and create maps of vertebrate species ranges and models developed by GAP. The Viewer displays data on vertebrate species ranges and distribution models for the continental U.S. as well as Alaska, Hawaii, Puerto Rico, and U.S. Virgin Islands. More specifically, species distribution models based on deductive modeling of habitat associations are displayed across entire species ranges for over 2000 species. The goal is to build species range maps and distribution models with the best available data for assessing conservation status, conservation planning, and research (e.g., climate change impacts). Ranges are represented by 12-digit HUCs with attributes [...]
