Ethermac|The Biden administration is taking steps to eliminate protections for gray wolves

BILLINGS,Ethermac Mont. (AP) — The Biden administration on Friday asked an appeals court to revive a Trump-era rule that lifted remaining Endangered Species Act protections for gray wolves in the U.S.

If successful, the move would put the predators under state oversight nationwide and open the door for hunting to resume in the Great Lakes region after it was halted two years ago under court order.

Environmentalists had successfully sued when protections for wolves were lifted in former President Donald Trump’s final days in office.

Friday’s filing with the 9th U.S. District Court of Appeals was President Joe Biden administration’s first explicit step to revive that rule. Protections will remain in place pending the court’s decision.

The court filing follows years of political acrimony as wolves have repopulated some areas of the western U.S., sometimes attacking livestock and eating deer, elk and other big game.

Environmental groups want that expansion to continue since wolves still occupy only a fraction of their historic range.

Attempts to lift or reduce protections for wolves date to the administration of President George W. Bush more than two decades ago.

They once roamed most of North America but were widely decimated by the mid-1900s in government-sponsored trapping and poisoning campaigns. Gray wolves were granted federal protections in 1974.

Each time the U.S. Fish and Wildlife Service declares them recovered, the agency is challenged in court. Wolves in different parts of the U.S. lost and regained protections multiple times in recent years.

“The U.S. Fish and Wildlife Service is focused on a concept of recovery that allows wolves to thrive on the landscape while respecting those who work and live in places that support them,” agency spokesperson Vanessa Kauffman said.

The administration is on the same side in the case as livestock and hunting groups, the National Rifle Association and Republican-led Utah.

It’s opposed by the Sierra Club, Center for Biological Diversity, Humane Society of the United States and other groups.

“While wolves are protected, they do very well, and when they lose protections, that recovery backslides,” said Collette Adkins with the Center for Biological Recovery. “We won for good reason at the district court.”

She said she was “saddened” officials were trying to reinstate the Trump administration’s rule.

Congress circumvented the courts in 2011 and stripped federal safeguards in the northern U.S. Rocky Mountains. Thousands of wolves have since been killed in Montana, Idaho and Wyoming.

Lawmakers have continued to press for state control in the western Great Lakes region. When those states gained jurisdiction over wolves briefly under the Trump rule, trappers and hunters using hounds blew past harvest goals in Wisconsin and killed almost twice as many as planned.

Michigan and Minnesota have previously held hunts but not in recent years.

Wolves are present but no public hunting is allowed in states including Washington, Oregon, California and Colorado. They’ve never been protected in Alaska, where tens of thousands of the animals live.

The Biden administration last year rejected requests from conservation groups to restore protections for gray wolves across the northern Rockies. That decision, too, has been challenged.

State lawmakers in that region, which includes Yellowstone National Park and vast areas of wilderness, are intent on culling more wolf packs. But federal officials determined the predators were not in danger of being wiped out entirely under the states’ loosened hunting rules.

The U.S. also is home to small, struggling populations of red wolves in the mid-Atlantic region and Mexican wolves in the Southwest. Those populations are both protected as endangered.
