RENO, Nev. — Under the threat of another legal battle, the U.S. Bureau of Land Management has quietly pulled the plug on a public-private partnership in northern Nevada aimed at shrinking the size of a wild horse herd through the use of contraceptives, according to documents The Associated Press obtained Tuesday.

The dispute in Nevada’s Pine Nut Mountains southeast of Carson City has divided horse advocates over the appropriate use of fertility-control drugs on the range.

The federal agency approved a pilot project in 2014 working with the American Wild Horse Preservation Campaign and the Gardnerville-based Pine Nut Wild Horse Advocates to treat a herd that a federal judge in Reno has forbidden the agency from gathering.

But an internal email obtained by AP shows the BLM suspended the project Monday after Friends of Animals threatened to sue based on claims the drug, PZP, harms horses and violates the judge’s order.

“Administration of PZP to these wild horses is hereby suspended, pending further review,” BLM Sierra Front Field Manager Bryant D. Smith wrote in informing his staff he’d revoked the decision record for the Fish Spring Wild Horses PZP Pilot Project.

While some groups advocate fertility control as a preferred alternative to government roundups, others say scientific research suggests PZP can have long-lasting physical, behavioral and social effects on wild horses. Among other things, they say mares that cannot get pregnant choose to leave their bands, creating instability that affects the health of the entire herd.

“We are extremely happy to have killed the pilot project and to put a stop to the forced drugging of Pine Nut mares with the fertility control pesticide PZP for a second time,” said Pricilla Feral, president of Friends of Animals, an international advocacy group founded in Connecticut in 1957.

The BLM maintains the Pine Nut herd is overpopulated, and it intended to round up more than 300 horses last year before U.S. District Judge Larry Hicks sided with Friends of Animals and blocked the effort.

Deniz Bolbol, the American Wild Horse Preservation Campaign programs director, said she fears the horses may end up in government holding pens.

“This is a lawsuit filed by people sitting in an office in Connecticut against the folks in Nevada doing the hard work on the ground to keep wild horses free on the range,” Bolbol said.
