BILLINGS, Mont. — The Trump administration finalized changes Friday to sweeping federal land use plans for the West, easing restrictions on energy companies and other industries in a way officials said would still protect a struggling bird species.

The changes by the U.S. Bureau of Land Management will guide efforts to conserve greater sage grouse, ground-dwelling birds that range across portions of 11 Western states.

Environmentalists said the widely anticipated move will undermine protections for the chicken-sized grouse. It would allow more oil and gas drilling, mining and other activities that can disrupt grouse breeding grounds.

But the changes secured key backing from Democratic and Republican governors in affected states, bolstering the administration’s position that revisions were needed to plans crafted under former President Barack Obama.

Oregon Gov. Kate Brown, a Democrat, said the changes marked “a shift away from planning toward active conservation and landscape management.”

The birds are known for an elaborate mating ritual in which males fan their tails and puff out yellow air sacs in their chests as they strut around breeding grounds known as leks. Their numbers have plummeted because of energy development, disease and other factors.

Opponents are expected to challenge the changes in court. Brian Rutledge with the Audubon Society said the revisions will make it harder to stop the long-term decline of sage grouse by giving oil and gas companies access to crucial grouse habitat.

“It’s a free for all, based on prioritizing fossil fuel extraction over any other use of the federal landscape,” Rutledge said.

The chairman of the U.S. House Natural Resources Committee, Arizona Democrat Rep. Raul Grijalva, said the changes would benefit former clients of acting Interior Secretary David Bernhardt. Bernhardt worked as an oil and gas industry lobbyist before joining the Trump administration.

Grijalva called the administration’s decision “a smash-and-grab-job on our environment.”

U.S. Bureau of Land Management acting Director Brian Steed said the changes address concerns aired by state officials that previous policies governing millions of acres of federal land were too restrictive.

Those policies had been memorialized in a 2015 partnership between Western states and the federal government, but officials from several states had since sought changes.

Steed said the revisions to the Obama-era plans were meant to move beyond what he called a “one-size-fits-all” approach under the old rules. He said they give more flexibility to land managers and states concerned about balancing economic development with protections for the bird.
