The Sheldon-Hart Mountain pronghorn (Antilocapra americana) herd is part of a large interstate metapopulation distributed across northwest Nevada, southeast Oregon, and portions of northeast California. Some animals travel up to 100 miles between summer and winter ranges and traverse multiple federal land jurisdictions, including the Sheldon National Wildlife Refuge, Hart Mountain National Wildlife Refuge, and surrounding Bureau of Land Management (BLM) lands. The herd can be characterized as conditionally or partially migratory with approximately 65% of collared animals exhibiting migratory tendencies. Major summer ranges include portions of the Hart Mountain Wildlife Refuge, Sheldon National Wildlife Refuge, and northern Black Rock Range in Nevada. Winter ranges are distributed across Hart Mountain and east to Catlow Valley, Sage Hen Flats in Oregon and portions of the Sheldon National Wildlife Refuge including Catnip Mountain, Gooch Table, Rock Springs Table, Summit Lake Indian Reservation, northern Calico Mountains. Challenges to this herd include invasive annual grasses and loss of native shrubs and grasslands, depletion of limited water resources due to severe droughts, and livestock fencing that prohibits efficient movements across the landscape. These data provide the location of winter ranges for female Pronghorn in the Sheldon-Hart Mountain herd in Nevada and Oregon. They were developed from 58 sequences collected from a sample size of 31 animals comprising GPS locations collected every 5-6 hours.
