Forty-six wild horses were captured on Tuesday during the ongoing helicopter roundup at the Reveille Horse Management Area in Nevada.

The 21 mares, 16 studs and nine foals / yearlings brought the two-day total of wild horses captured to 78, according to the Bureau of Land Management. No injuries or deaths have been reported.

BLM plans to capture up to 135 wild horses from the HMA and surrounding area, which is located about 50 miles east of Tonopah, Nevada.

Of those, 80 wild horses will be permanently removed from the range and put up for adoption; 55 will be released, with all mares treated with fertility control vaccine.

A portion of the Reveille HMA is subject to a 1987 court order and 2001 and 2001 Interior Board of Land Appeals orders requiring BLM to conduct an annual population count. If the count exceeds BLM’s Appropriate Management Level (set at 138 wild horses in 2001), the agency has 120 days to begin a roundup to removed “excess” wild horses, beginning with wild horses outside of the HMA’s boundaries.

The Tonopah Resource Management Plan allows BLM to reduce the wild horse population to a level that will accommodate up to three years of population growth before again reaching Appropriate Management Level.

The goal for the upcoming roundup: reduce the population to 91 wild horses. The current population is estimated at 173 wild horses, based on an inventory flight in February 2016 and an annual estimated growth rate of 15 to 20%, according to BLM.
