HELENA — A federal appeals court has denied a conservation group's request to block the use of a helicopter to haze wild bison in southwestern Montana back into Yellowstone National Park.
A three-judge panel from the 9th U.S. Circuit Court of Appeals denied the injunction request Monday.
The Alliance for the Wild Rockies filed the request as part of its legal challenge that low-altitude helicopter hazing harasses and displaces federally protected grizzly bears in the area.
The group is appealing U.S. District Judge Charles Lovell's ruling in March against its lawsuit.
Montana Department of Livestock spokesman Steve Merritt said Tuesday the annual bison-hazing operation appears to be wrapping up for the season.
He says state officials moved about 350 bison Monday from the Hebgen Basin west of Yellowstone.
