2021 Rock Springs Wild Horse Gather

Background and Details of Gather:

The BLM Wyoming Rock Springs and Rawlins field offices will remove wild horses from the Great Divide Basin, Adobe Town, Salt Wells Creek, White Mountain and Little Colorado Herd Management Areas (HMAs) in southwestern Wyoming. 

The BLM estimates the wild horse population across the five HMAs to be approximately 5,105, which is more than double the combined appropriate management level of 1,550-2,145 horses. The gather is being conducted to address the overpopulation on the HMAs, prevent deterioration of the rangeland due to the overpopulation, remove horses from private lands and areas not designated for their long-term use, and comply with the 2013 Consent Decree between the Rock Springs Grazing Association and the BLM. 

The BLM plans to remove approximately 3,500 horses to return wild horse populations to within the appropriate management levels. BLM estimates that around 800 animals that are gathered will be returned to the range. Any mare returned to an HMA will be treated with temporary fertility control. Managing wild horses at appropriate levels allows BLM to maintain rangeland and wild horse heard health and reduce trespass onto private land and highways.

The gather will begin on or after October 7, 2021.

The BLM uses a federal contractor to gather wild horses from HMAs where the BLM has determined excess animals exist. The contractor uses a helicopter to locate and herd horses toward a set of corrals. The helicopter is assisted by a ground crew and a domesticated horse to lead the gathered horses into the corrals. If needed, the ground crew may assist the helicopter by roping wild horses from horseback.

The BLM takes the humane treatment of wild horses and burros during gather operations very seriously. Helicopters have been shown to be the most humane method to gather horses.

Public Observation:

Opportunities are available for the public to observe gather operations, provided that doing so does not jeopardize the safety of the animals, staff, contractors and observers, or disrupt gather operations. The BLM will escort the public to gather observation sites located on public lands or authorized private lands. If you are interested in watching the gather, you must contact Brad Purdy at bpurdy@blm.gov.

Observers must provide their own transportation, water and food. The BLM recommends a four-wheel drive, high clearance vehicle, and footwear and clothing suitable for harsh field conditions. Public restrooms will not be available onsite. 

Adoption Info:

The BLM will transport all wild horses removed from the range to holding facilities in Rock Springs, Wyoming; Wheatland, Wyoming; and other locations to be determined where the horses will be freeze branded, vaccinated, dewormed and given a Coggins test. The corrals receiving the horses from the gathers will not be taking requests from the public to hold specific horses.

Some of the horses may also be taken to the Wyoming Honor Farm in Riverton or the Mantle Adoption and Training Facility in Wheatland for gentling before being made available for adoption.

Gathered wild horses will be available for adoption through the BLM Wild Horse and Burro Adoption Program.
