Pronghorn are endemic to North America and make their home in the high plains and vast sagebrush sea of the American West, and like many ungulate species, their survival relies on the ability to roam freely. They need to be able to migrate across large tracks of ground to avoid bad weather and find food. The North Platte River Valley along the Colorado-Wyoming border is rich with wildlife diversity held mostly in private ownership. The rangelands in this area stewarded by ranchers make ideal habitat for pronghorn and other wildlife species. However, the miles of fences used to keep cattle in pastures are often barriers to the pronghorn’s and other wildlife’s movements.
