The complete county distribution, spread across 16 Oregon counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Oregon’s 1,180 pronghorn records belong to the open country east of the Cascades. Union, Harney, and Lake counties carry the heaviest counts, and the named sites trace the sagebrush heart of the state, from Steens Mountain and its wilderness area past Malheur National Wildlife Refuge to Fremont and Winema national forests and Klamath Marsh National Wildlife Refuge.

Built for open ground

The pronghorn is the fastest land mammal in North America, capable of sprints near 55 miles per hour, and its enormous eyes spot movement at long distance. Speed and eyesight are its whole defense, which is why it lives where it can see and run: broad sagebrush flats and rolling grassland. It browses sagebrush, forbs, and grasses, and rather than jumping fences it prefers to slip underneath, a quirk that shapes how herds move across rangeland.

Fawns on the spring flats

Oregon reports rise from April and crest in May and June, when does drop their fawns on open ground and the high desert greens up. Herds shift between summer and winter range as snow and forage dictate, and records continue through every month, with a smaller December pulse as animals bunch up on winter range.

Status in Oregon

NatureServe ranks the pronghorn S4, Apparently Secure, in Oregon, and the species is native to the state. USGS NAS does not list it as nonindigenous here.
