A federal judge ruled on Wednesday, September 7, the U.S. government was wrong to exclude large areas of the Rocky Mountains when it designated almost 40,000 square miles of habitat as critical to the survival of imperiled Canada lynx.
U.S. District Judge Dana Christensen in Montana ordered the U.S. Fish and Wildlife Service to consider adding more habitat for the wild cats in several states.
The judge cited the presence of a reproducing lynx population in the southern Rocky Mountains of Colorado. Agency officials concluded that area was “not essential” for the recovery of the species, pointing in part to low population densities of snowshoe hares that lynx eat.
“The (Fish and Wildlife) Service’s own representations suggest that parts of Colorado constitute suitable critical habitat,” Christensen wrote. He added that snowshoe hares are “certainly present” in the southern Rockies at densities “at or near” the level needed to support lynx.
“In such a close call, the (Endangered Species Act) demands that the tie go to the species,” the judge said.
Lynx are elusive, forest-dwelling animals and there are no reliable population estimates. Canada lynx were listed as threatened in 2000, but a dispute lingers as to “where” lynx should receive the strongest protections.
Christensen also ruled that officials failed to analyze the potential for lynx to thrive in portions of Montana and Idaho when they made their critical habitat designation in 2014.
But the judge agreed with the government that a critical habitat designation wasn’t needed in Oregon and the Kettle mountain range in Washington state; where there is little evidence of lynx.
That means lynx in those areas will be protected from hunting and trapping, but there will be less stringent reviews of human activities that could affect the dense forests they need to survive.
Wildlife advocates sued the government following the 2014 habitat designation. They said Wednesday’s ruling could mark a “turning point” in lynx recovery.
“The species really now has a fighting chance,” said attorney Matt Bishop with the Western Environmental Law Center, who represented some of the plaintiffs in the case. “The feds can no longer discard the southern Rockies or its importance for lynx.”
Fish and Wildlife Service spokeswoman Serena Baker said the agency was disappointed with the ruling on the southern Rockies, Montana and Idaho—but pleased that aspects of the 2014 habitat designation were left in place. She declined to say if the agency would appeal Christensen’s ruling or how long it would take to comply.
