Western Migrations Reports

Ungulate Migrations of the Western United States is an annual conservation-focused publication commissioned by the U.S. Geological Survey to document seasonal migration routes and habitats of mule deer, elk, pronghorn, and other ungulates in the western U.S. The migrations cover long distances, and are threatened by roads, fences, and other forms of human development. The maps and reports provide critical information to help land managers, conservationists, planners, and others make decisions using the best available data and science to maintain these big-game migrations.

The InfoGraphics Lab collaborates with the USGS Corridor Mapping Team on the mapping effort for these reports. Contributors include scientists, researchers, wildlife managers, and biologists including those from Federal, State, and Tribal agencies across the western United States.
