US wildlife officials have agreed to craft a new habitat plan for the snow-loving Canada lynx that could include more land in Colorado and other western states where the rare animals would be protected.
A legal agreement made public on Tuesday said that the US Fish and Wildlife Service faces a 2024 deadline to draft the new plan for the wild cats after settling a legal challenge from two environmental groups — Wild Earth Guardians and Wilderness Workshop.
US District Judge Dana Christensen issued an order late on Monday approving the settlement.
The groups sued to enforce a prior court ruling from Ms Christensen that said federal officials wrongly excluded areas of Colorado, Montana and Idaho when they designated almost 104,000 square kilometres in 2014 as critical for the lynx’s long-term survival.
On land designated as critical, federal agencies are required to consult with wildlife officials before taking or allowing any activities that could destroy or alter the habitats of a protected species. Those consultations can potentially lead to restrictions of logging in federal forests or limitations on dirt roads used for recreation.
Ms Christensen cited the presence of a reproducing lynx population in the southern Rocky Mountains of Colorado.
Agency officials had earlier concluded that Colorado and adjacent areas of Wyoming and New Mexico were “not essential” for the recovery of the species, pointing in part to low population densities of snowshoe hares that lynx eat.
To comply with the judge’s order, the Fish and Wildlife Service will evaluate which parts of the Southern Rockies and elsewhere are critical for lynx and propose them for potential protections by November 21, 2024, a statement provided by agency representative Joe Szuszwalak said.
Lynx are elusive, forest-dwelling animals. There is no reliable population estimate, but several hundred are believed to roam parts of the US Rocky Mountains.
The animals also are found in Minnesota, Maine, Washington state and occasionally Michigan.
They were reintroduced to Colorado beginning in the late 1990s and listed as threatened under the Endangered Species Act across the contiguous US in 2000.
During Donald Trump’s presidency, officials said the lynx had recovered and no longer needed protection after their numbers rebounded in some areas. President Joe Biden’s administration reversed course in November and agreed to keep the lynx’s threatened species protections. That did not resolve the dispute over what areas they would need to survive.
“There’s a lot of really good habitat in Colorado — wilderness and really remote areas,” said John Mellgren, a lawyer who represented the environmental groups that reached the settlement.
But he added that those areas face increased pressure as trees in forested areas are killed by beetles, wildfires and other problems that are being worsened by climate change.
Some scientists say climate change could undo progress in lynx recovery by melting away their snowy habitat and decreasing the availability of snowshoe hares.
US government biologists in 2016 predicted some lynx populations would disappear by 2100. That was based on models predicting widespread and substantial habitat losses because of climate change.
Under Mr Trump, officials shortened their time span for considering climate change threats, from 2100 to 2050, because of what they said were uncertainties in long-term climate models. A government assessment based on that shortened time span concluded lynx populations had increased versus historical levels in parts of Colorado and Maine.
