The BLM plans to round up and remove wild horses from five Wyoming herds, shrinking free-roaming populations.
What’s at risk
Wild horse herds in the Antelope Hills, Crooks Mountain, Green Mountain, Lost Creek, and Stewart Creek areas face removal under new management plans. The BLM is labeling horses 'excess' to justify gathers that permanently reduce herd sizes.
If this goes through
Updated herd management plans will lock in lower population targets across all five areas, and gathered horses will be removed from the range, likely permanently.
Our plain-English read of the official notice ↗. Check it against the agency’s own words below.
In the agency’s own words
The Bureau of Land Management Lander and Rawlins field offices propose to update Herd Management Area Plans (HMAP) for the Antelope Hills, Crooks Mountain, Green Mountain, Lost Creek, and Stewart Creek herd management areas (HMAs), referred to as the Red Desert Complex. The field offices also intend to gather excess wild horses from the HMAs.
