The Bureau of Land Management on Thursday released 97 wild horses, including 48 mares treated with fertility control, on the 18th day of a 947-horse helicopter roundup on the Owyhee Complex in Humboldt and Elko Counties in Nevada. No wild horses were killed on Thursday.

A total of 552 wild horses have been captured during the roundup, so far. Twelve wild horses have been put down for reasons that have also included poor body conditions, a developmental hernia, “no teeth / very old age,” and “chronic injury (fractured / broken ankle).”

A total of 166 wild horses have been released, according to BLM’s gather report, including 68 mares treated with the safe, proven and humane fertility control vaccine PZP, 94 stallions and four foals.

The agency plans to permanently remove 615 wild horses from their home range. Of the horses released, BLM plans to treat up to 185 mares with PZP.

“The purpose of the gather is to prevent undue or unnecessary degradation of the public lands associated with excess wild horses, to restore a thriving natural ecological balance and multiple-use relationship on public lands…,” BLM wrote in a press release. “By balancing herd size with what the land can support, the (field office) aims to address resources issues related to drought and past fire damage and protect habitat for other wildlife species such as sage grouse, pronghorn antelope and mule deer.”

Prior to the roundup, BLM estimated the population of the complex at 1,188 wild horses, including foals this year, based on a May 20 flight over the complex.

The Owyhee Complex is made up of the Little Humboldt, Little Owyhee, Owyhee, Rock Creek and Snowstorm Mountains Herd Management Areas. The total agency-set “Appropriate Management Level” for the 1.055 million-acre complex is 621-999 wild horses.

By comparison, BLM allows 153,624 Animal Unit Months for seasonal private livestock grazing on allotments that overlap the Owyhee complex by 5-91%, the equivalent of 12,802 cow-calf pairs annually, according to planning documents. One Animal Unit Month is a month’s forage for one horse, one cow / calf pair or five sheep.

Wild horses removed from the range will be shipped to the Sutherland, Utah, Off-Range Wild Horse and Burro Corrals, where they will be prepared for adoption or sale.

BLM last conducted a roundup on the Owyhee Complex in 2018. The “emergency” roundup followed a wildfire that burned 438,000 acres in northeastern Nevada. A total of 1,178 wild horses were captured. Of those, 280 wild horses were returned to the range, including 127 mares treated with fertility control, and 25 wild horses were killed.

In 2016, BLM captured 1,832 wild horses on the complex. Of those, 402 were re-released, including 199 mares treated with fertility control. Eighteen wild horses died.
