In 1971, wild horses and burros were found roaming across 53.8 million acres of Herd Areas (HAs), of which 42.4 million acres were under the Bureau of Land Management’s (BLM’s) jurisdiction. Today the BLM manages wild horses and burros in subsets of these HAs, known as Herd Management Areas (HMAs) that comprise 31.6 million acres, of which 26.9 million acres are under BLM management.
The Little Colorado HMA encompasses 519,541 acres of BLM administered public lands. The majority of the HMA consists of consolidated public lands along with state school sections and, in the south of the HMA, Bureau of Reclamation lands. The HMA is bounded on the west by the Green River, on the east by Highway 191on the north by the Pinedale/Rock Springs Field Office boundary. The area is mostly rolling hills with significant canyons breaking up the area. Elevations range from approximately 6,300 to 7,900 feet, and precipitation ranges from 6-10 inches, predominately in the form of snow. The area is unfenced except for sections of the boundary fence between the Rock Springs and Pinedale Field Offices, and along Highway 191. The HMA is divided among Sublette, Lincoln, and Sweetwater counties.
