BILLINGS, MONTANA — U.S. wildlife officials finalized a recovery plan for imperiled populations of Canada lynx on Wednesday and proposed new habitat protections in the southern Rocky Mountains for the forest-dwelling wildcats that are threatened by climate change.
The fate of the proposal is uncertain under President-elect Donald Trump: Officials during the Republican’s first term sought unsuccessfully to strip lynx of protections that they’ve had since 2000 under the Endangered Species Act.
Almost 20,000 square kilometers of forests and mountains in Colorado and northern New Mexico are covered under the habitat proposal. That’s different from a previous plan that left out the southern Rockies and concentrated instead on recovery efforts elsewhere, including Wyoming, Montana, Minnesota and Maine.
“This is a significant change and a good one,” said Matthew Bishop, an attorney for Western Environmental Law Center who has been involved in efforts to protect lynx through court actions. “They weren’t really committing to conserve lynx in Colorado anymore, and now they are.”
Areas of protected habitat also are being added in Idaho and Montana. Protected areas in Wyoming would be sharply reduced under Wednesday’s proposal.
Wildlife officials said they were removing locations where they consider lynx unlikely to thrive in the future, while adding new areas that the latest science suggests are more suitable to their long-term survival.
Lynx are elusive animals that live in cold boreal forests and prey primarily on snowshoe hares.
They originally received federal protections because the U.S. Forest Service and the Bureau of Land Management didn’t have sufficient regulations in place to shield their populations from potential harm. Those protective rules are now in place, but climate change has emerged as a new, worsening threat.
Warmer temperatures are melting away the lynx’s snowy habitat and could decrease the availability of snowshoe hares. Declines for lynx are expected across the contiguous U.S. under even the most optimistic warming scenario that officials have considered.
Most areas suitable for lynx are in Canada and Alaska, where the animals are widespread and hunting and trapping of them is allowed.
Their numbers never were great in the contiguous U.S., which is at the southern fringe of the species range, but the hope is to maintain some population strongholds so they can persist in a warmer world.
The changes announced Wednesday follow a 2016 court ruling that faulted federal wildlife officials for not designating protections for lynx habitat in Colorado and some parts of Montana and Idaho.
There are more than 1,100 lynx in the contiguous U.S., according to estimates from scientists. Those numbers are expected to plummet in some areas, and officials are aiming for a minimum contiguous U.S. population of a combined 875 lynx over a 20-year period.
More than 200 lynx were reintroduced in Colorado beginning in 1999 and at the time their prospects were considered uncertain.
“There were concerns about whether it would stick,” said U.S. Fish and Wildlife Service lynx biologist Jim Zelenak. “But they do seem to be hanging on.”
Now that area could become one of the future population strongholds, with the southern Rockies in Colorado and the region around Yellowstone National Park are most likely to have temperatures favorable to lynx for the longest time, he said.
Maine has the most lynx currently but is expected to be hit harder by climate change.
“We’ve got this overarching threat of climate warming, and so we want to do everything we can to minimize the effects that we can control,” Zelenak said. “So we don’t want to put roads in the wrong places. We don’t want to permanently convert very much of the habitat at all in the hopes that we can keep these populations viable coming into a warming future.”
Habitat protections in Maine and Minnesota would remain unchanged under the proposal.
A final decision is expected late next year.
