White Mountain/Little Colorado Gather Environmental Assessment Available

The Bureau of Land Management Rock Springs Field Office is requesting public input on a proposal to gather excess wild horses from the White Mountain/Little Colorado Herd Management Areas (HMA). The comment period will be open for the Wild Horse Gather Environmental Assessment (EA) until May 6.

Population surveys show the current population in the White Mountain/Little Colorado HMAs is slightly more than 800 wild horses. The Appropriate Management Level (AML) for White Mountain HMA is between 205-300 horses, and the AML range for Little Colorado HMA is 69-100.

AMLs for the HMAs were established through an agreement with private land owners and wild horse advocacy groups, and confirmed in the 1997 Green River Resource Management Plan. The proposed gather, may include using fertility control, as well as adjusting sex ratios. The two HMAs were last gathered in November 2007.

A copy of the EA and more information is available at:
