Modified White Mountain/Little Colorado Wild Horse Gather Decision Released

The Bureau of Land Management Rock Springs Field Office modified the decision record (DR) for the wild horse gather slated for the White Mountain/Little Colorado Herd Management Areas (HMAs). The modified decision returns only gelded wild horses to the herd management areas, and does not include spaying. The goal of the gather is to help create a minimally reproducing herd.

This modified decision returns about 177 geldings to the two HMAs to reach appropriate management level (AML). AML is the point at which the herd’s population is consistent with the land’s capacity to support wild horses in balance with other public rangeland uses and resources. The projected wild horse population remaining on the range following the gather would be about 205 in the White Mountain HMA and about 69 in the Little Colorado HMA.

The current population estimate in the White Mountain/Little Colorado HMAs is nearly 1,000 wild horses. AML for White Mountain HMA is between 205-300 horses, and for Little Colorado HMA the number 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 two HMAs were last gathered in November 2007. The gather is scheduled to start in mid August 2011 and expected to conclude in early September.

Initial public scoping on the proposed gather was conducted in April and May 2010. The EA was made available for public comment in April and May 2011, and all comments concerning potential impacts were addressed in the EA. The DR is subject to administrative review through the appeal process, which is outlined in the DR. For more information, visit:

All gathered horses will be examined by a veterinarian, dewormed, Coggins tested, and given booster shots prior to being made available for adoption to qualified applicants. Adoption applications and requirements for the White Mountain/Little Colorado gathered horses are available at:
