A wild horse grazes in 2012. The U.S. Bureau of Land Management is holding off on plans to return 186 wild horses to the range in central Nevada pending the review of an appeal filed by a rancher and rural county opposed to the move.

RENO, Nev. — The U.S. Bureau of Land Management is holding off on plans to return 186 wild horses to the range in central Nevada pending the review of an appeal filed by a rancher and rural county opposed to the move.

The agency originally had planned to return 104 mares treated with a fertility control vaccine and 82 studs to the Fish Creek Herd Management Area (HMA) near Eureka on Friday.

They were among 424 horses removed from the HMA during a roundup that ended earlier this week.

Rancher Kevin Borba, who joined Eureka County in filing the appeal with the Interior Board of Land Appeals on Friday, says the BLM has drastically reduced his livestock allotments in the HMA while allowing well over twice as many wild horses in it as it can support.

The bureau says the HMA's "appropriate management level" of wild horses is between 101 and 170.
