Wild horse roundup in Montana, Wyoming planned

BILLINGS, Mont. — A federal judge has rejected a request to halt a roundup of about 190 wild horses in the Pryor Mountains along the Montana-Wyoming border.

The roundup had been delayed since Monday as U.S. District Judge Emmet Sullivan considered an injunction sought by two Colorado-based advocacy groups.

Sullivan denied the request Wednesday. The Bureau of Land Management, which operates the 38,000-acre Pryor Mountain Wild Horse Range, says the roundup will begin Thursday.

The roundup will capture the range’s entire population, with 70 adult horses and their foals to be kept for adoption. The remaining horses will be freed after some of the mares are given a contraceptive vaccine.

Opponents say the roundup could end up ruining one of the most genetically pure herds of Spanish colonial horses in the country.
