Three wild horses died and 160 were captured on the second day of a helicopter roundup in Wyoming’s Red Desert Complex on Wednesday.
Two colts died of capture shock, according to the Bureau of Land Management. One died shortly after being treated, the other en routed to a veterinary hospital in Lander, Wyo., according to BLM. A third horse was put down because of a pre-existing condition, according to BLM’s gather report, but no explanation was given as to the condition and no veterinary report was posted.
These were the first three known deaths during the roundup, which is expected to last six to eight weeks.
So far, 347 wild horses have been captured. BLM intends to remove 2,670 adult wild horses — 76% of the Red Desert population — from their home range.
The agency claims that the roundup is needed because of what it deems overpopulation of wild horses, deterioration of rangeland and requests to remove wild horses from neighboring private land. The current population is estimated by the agency to be about 3,500 wild horses.
BLM intends to select mares and stallions from among those captured “to ensure genetic variability and to preserve the New World Iberian Genotype present in the complex.” All mares returned are to be treated with fertility control vaccine.
Most of the wild horses captured will be transported to holding facilities in Rock Springs, Wyo., Canon City, Colo., or Axtell, Utah., seperated from their family bands, sorted by age and gender, then offered for adoption. Some will be taken to the Wyoming Honor Farm in Riverton, Wyo., or the Mantle Adoption and Training Facility in Wheatland, Wyo., for gentling before being offered for adoption.
On Wednesday, 89 wild horses were shipped to Rock Springs, 75 to Axtell.
BLM’s goal of capturing and removing “adult” wild horses implies that foals may not be counted. In 2017, BLM Wyoming conducted a roundup in the state’s Checkerboard region during which it quickly became clear to observers that foals and weanlings were not being counted toward the total. A federal judge rejected a preliminary injunction intended to stop the roundup, however.
The BLM-set “Appropriate Management Level” for the Red Desert Complex is 481-725 horses — as low as one horse for every 1,566 acres of the complex, which includes 703,500 acres of public land and 49,500 acres of private land.
For livestock in the complex, BLM has allotted 69,889 Animal Unit Months. One AUM is the amount of forage needed to sustain one cow-calf combination, one horse, or five sheep for a month. Actual use has varied from 10-70% of authorized use in recent years, depending on availability of forage and water, according to the agency.
The Red Desert Complex includes the Antelope Hills, Crooks Gap, Green Mountain, Lost Creek and Stewart Creek Herd Management Areas in south-central Wyoming.
