Roughly two-thirds of the federal oil and gas leases offered in a Colorado auction that spurred concerns about the impact on wildlife were sold Thursday.

The Colorado office of the Bureau of Land Management said leases on 49 parcels totaling 42,149 acres of public lands sold for $601,541. As part of its mandated quarterly auctions, the BLM offered a total of 73 parcels over 64,745 acres in Cheyenne, Garfield, Jackson, Kiowa, Moffat, Rio Blanco, Routt and Weld counties.

The agency deferred action on tracts totaling 13,946 acres in northwest Colorado to address state officials’ concerns about the potential effects on wildlife habitat and migration corridors. Gov. Jared Polis issued an executive order in August that directs state agencies to take steps to conserve big-game wintering areas and migration corridors.

A 2018 order by former Interior Secretary Ryan Zinke directs federal agencies to conserve and improve big-game winter range and migration corridors in the West.

“The BLM will continue to coordinate with the State to refine wildlife habitat data to to develop mutually beneficial strategies to protect big-game habitat and migration corridors consistent with the Secretarial Order. We are eager to work with the state to ensure these objectives are applied across all land ownership — federal, state and private,” Colorado BLM spokesman Jayson Barangan said in an email Friday.

The same consideration wasn’t given to the greater sage grouse, according to Nada Culver, the National Audubon Society’s vice president for public lands. Most of the 33 parcels up for lease in Jackson County in northwest Colorado are in sage grouse habitat. None of those leases were pulled from the sale.

It wasn’t immediately clear how many of the parcels in sage grouse territory were leased. Culver noted that the federal conservation plan for sage grouse in Colorado says that agencies should prioritize mineral development outside of the bird’s habitat.

At one time, greater sage grouse were under review for possible addition to the endangered species list. In 2015, the Interior Department decided against listing it, but wrote conservation plans for its territory across the West.

“It’s very troubling to not see them taking those commitments seriously,” Culver said. ” I think they’re really pushing people who care about sage grouse and, of course, the sage grouse itself.”

Conservation and wildlife organizations filed protests of the lease sale. Concerns included the impacts on wildlife, Dinosaur National Monument and Rocky Mountain National Park.

Oil and gas leases are awarded for at least 10 years. The federal government receives a royalty of 12.5 percent of the value of production. The state receives 48 percent of revenues from leases issued on public lands in Colorado.
