Sulphur Wild Horse Gather Concludes With Return of Horses to Management Area

The Bureau of Land Management’s (BLM) Sulphur Wild Horse Management Area (HMA) gather concluded Saturday, December 18 with the return of 60 of the 90 gathered horses to the HMA.  
The returned horses included 38 mares that were treated with a fertility control vaccine to slow population growth and 22 stallions.   BLM had hoped to capture and treat 90 mares in the HMA during the gather but prevailing weather conditions precluded reaching this goal in a manner that was safe for both the horses and the gather personnel.
Because fewer mares were treated with fertility control than planned, the next scheduled gather for the Sulphur HMA may occur sooner than originally anticipated. With the help of the fertility control that was given to the 38 released mares, BLM estimates that the next gather would need to take place in three to five years. Timing would depend on the results of a scheduled population inventory of the HMA and the availability of forage and water, both of which are closely monitored.
A total of 30 horses, four young mares and 26 foals, from the Sulphur HMA were shipped to the Central Utah Correctional Facility in Gunnison, Utah. All of the animals from this gather will be available for adoption through the BLMs Internet Adoption program in early March ( If any horses are not adopted, they will be cared for in long-term pastures, where they retain their “wild” status and protection under the 1971 Wild Free-Roaming Horses and Burros Act. The BLM does not send any horses to slaughter.
The Sulphur HMA covers approximately 265,676 acres of public, state and private lands, located in Beaver, Iron, and Millard counties. The Appropriate Management Level (AML) established for the Sulphur HMA is a population range of 165 to 250 wild horses. The current estimated population of wild horses within the Sulphur HMA is around 250. 
AML is determined through land-use planning efforts that involve public participation, vegetation inventories and allocation of forage in terms of animal unit months; the BLM determines the appropriate number of wild horses that each HMA can support in balance with other uses of and resources on public land. Planning efforts include an inventory and the monitoring of all uses of the public rangelands.

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.
