BLM to seek public comment on proposed wild horse management in the Swasey Herd Management Area

FILLMORE, Utah — The Bureau of Land Management (BLM) Fillmore Field Office is seeking public comment on an environmental assessment (EA) analyzing a proposed wild horse gather, removal, and the use of population growth suppression in the Swasey Herd Management Area (HMA).

The Swasey Herd Management Area (HMA) is located in Juab and Millard Counties, about 50 miles west from Delta, Utah. It consists of approximately 120,113 acres of public and state lands. The HMA has an estimated population of 721 wild horses, more than seven times over the Appropriate Management Level (AML) upper limit. The AML is 60-100 wild horses.   

The EA analyzes a proposal to gather and remove excess wild horses and in the vicinity of the HMA. The BLM proposes to remove excess horses down to AML for a variety of reasons including but not limited to: resource impacts related to over AML horse population, habitat suitability, and actions necessary to improve Utah Rangeland Health and Standards in the area impacted by the overpopulation of horses.

The EA, including maps, is available on the BLM’s ePlanning website at:

Written comments will be accepted by letter or on ePlanning until Feb. 20, 2020. Special attention will be given to those comments that contain new technical or scientific information relevant to the proposed action. Comments should be as specific as possible. Comments that contain only opinions or preferences will not receive a formal response but may be considered in the BLM decision-making process.  Please reference “Swasey Herd Management Area” when submitting comments.
