BLM Signs Wild Horse Gather Environmental Assessment, Plans Gathers

The Bureau of Land Management High Desert District Office (BLM) announces the Environmental Assessment (EA) for proposed wild horse gathers in Adobe Town and Salt Wells Creek Herd Management Areas (HMAs) near Rawlins and Rock Springs has been signed and is available for review.

The Finding of No Significant Impact (FONSI), Decision Record and EA for gathering wild horses has addressed public comments. The documents may be found online at:

As a result of this decision, the BLM will gather approximately 1,950 wild horses, treat and release approximately 100 mares with the fertility-control vaccine Porcine Zona Pelludica (PZP), and remove approximately 1,580 excess wild horses from the Herd Management Area, leaving a total of approximately 860 wild horses in the area, which is the appropriate management level (AML) for this herd complex. AML is the point at which the herd’s population is consistent with the land’s capacity to support wild horses in balance with other public rangeland uses and resources. The gather will start October 1 and is expected to conclude November 8.

“Our goal is to manage for healthy public lands and healthy wild horses,” John Ruhs, High Desert District Manager said. “We made the decision to conduct this gather after extensive public input and review of the best scientific information available to us.”

All gathered animals will be examined, and if needed, treated by a veterinarian. About 1,580 animals will be available for adoption to citizens willing and prepared to provide good care.

The gather is necessary to maintain these wild horse herds within the established AMLs and to comply with the 1971 Wild Free-Roaming Horse and Burro Act and the 2003 Wyoming Consent Decree.

Population surveys conducted in July 2009 revealed approximately 1,950 horses within the two adjacent HMAs. Both HMAs are over the appropriate management levels (AMLs). The AML range for the Adobe Town HMA is 610-800 wild horses and the AML range for the Salt Wells Creek HMA is 251-365 wild horses.

The BLM manages wild horses and burros on public rangelands in a manner consistent with its overall multiple-use mission, taking into account all natural resources and users of the public lands. As mandated by the Wild Free-Roaming Horses and Burros Act of 1971, the BLM protects, manages, and controls wild horses and burros to ensure that healthy herds thrive on healthy rangelands. Through land-use planning efforts that involve public participation, the BLM determines the appropriate number of wild horses that each HMA can support.

The BLM manages more than 245 million acres of public land, the most of any Federal agency. This land, known as the National System of Public Lands, is primarily located in 12 Western states, including Alaska. The BLM also administers 700 million acres of sub-surface mineral estate throughout the nation. The BLM's mission is to sustain the health, diversity, and productivity of America’s public lands for the use and enjoyment of present and future generations. In Fiscal Year 2015, the BLM generated $4.1 billion in receipts from activities occurring on public lands.
