The Bureau of Land Management (BLM) concluded a wild horse helicopter gather at the Reveille Herd Management Area (HMA), located about 50 miles east of Tonopah in Nye County, Nevada, on Feb. 3.

The BLM gathered 151 and removed 81 wild horses. Sixty-eight horses, both mares and stallions, were released back onto the range. All mares that were released—a total of 30—were treated with the fertility control vaccine PZP-22—a temporary fertility-control vaccine that can prevent pregnancy in wild horses for one to two years—to slow population growth in the HMA.

The BLM said it conducted the gather was to remove excess horses and apply fertility control to mares released back to the HMA to slow population growth rates and assist in maintaining wild horse population levels below the established appropriate management level (AML). The estimated post gather population of 90 wild horses will allow for at least three years until the population nears the established AML and another gather is scheduled.

All the horses removed were transported to the Ridgecrest Regional Wild Horse and Burro Corrals, in California, where they will be vaccinated, dewormed, and examined by a veterinarian. Once the horses have their vaccination boosters they will be available for adoption to qualified applicants. Information on and requirements for adoption are available at
