A lawsuit has been filed over the U.S. Fish and Wildlife Service's decision not to provide wolverines with Endangered Species Act protection/USFWS
Whether climate change is adversely impacting wolverines, something the U.S. Fish and Wildlife Service believes is uncertain, is being challenged by a coalition of conservation groups that is suing the agency to provide Endangered Species Act protection to the small carnivores.
Earlier this year Noreen Walsh, director of the agency's Mountain-Prairie Region, which includes Wyoming and Montana, decided there wasn't enough evidence to demonstrate climate change was adversely affecting the species, according to a story in the Los Angeles Times. That development led other biologists outside Fish and Wildlife to speculate that politics, not science, had forced that decision.
On Monday eight conservation groups announced they would challenge that decision in court.
Back in February 2013 the Fish and Wildlife Service proposed to list the wolverine as a threatened species under the Endangered Species Act after the agency's biologists concluded global warming was reducing the deep spring snowpack pregnant females require for denning.
But, according to the conservation groups, "after state wildlife managers in Montana, Idaho and Wyoming objected, arguing that computer models about climate change impact are too uncertain to justify the proposed listing," Ms. Walsh ordered her agency to withdraw the listing. The reversal came despite confirmation by a panel of outside experts that deep snow is crucial to the ability of wolverines to reproduce successfully, the groups said.
'The wolverine is a famously tough creature that doesn't back down from anything, but even the wolverine can't overcome a changing climate by itself,' said Earthjustice attorney Adrienne Maxwell in a release. 'To survive, the wolverine needs the protections that only the Endangered Species Act can provide.'
The groups behind the lawsuit are the Center for Biological Diversity, Conservation Northwest, Friends of the Clearwater, Greater Yellowstone Coalition, Idaho Conservation League, Jackson Hole Conservation Alliance, Klamath-Siskiyou Wildlands Center, and Rocky Mountain Wild.
Wolverines have been spotted in Denali National Park, Yosemite National Park, Yellowstone National Park, Grand Teton National Park, Glacier National Park, and North Cascades National Park, among others. It's difficult to say just how many wolverines are wandering around the parks. Their extensive travels, sneaky scavenger-like maneuvering, and solo dwelling make it difficult for researchers to closely monitor their patterns.
In their lawsuit (attached), the groups maintain that "the best available scientific information" predicts that snowfields that wolverines rely upon will shrink by nearly a third by 2045 due to climate warming, and by more than 60 percent by 2085.
"This threat of habitat loss associated with climate change is compounded by other threats facing the wolverine population in the lower-48 states, including highly isolated and fragmented habitat, extremely low population numbers, recreational wolverine trapping in Montana and incidental trapping elsewhere, and disturbance from winter recreation activities that has been demonstrated to disrupt wolverine reproductive denning," the lawsuit states.
Against this data, the lawsuit added, "FWS did not identify any new scientific information that cast doubt on the previous conclusions of the agency's own expert biologists. Nor did FWS identify any existing scientific information that the agency's biologists had overlooked. Instead, FWS attempted to apply a new interpretation of the existing scientific record in an effort to justify a refusal to afford the wolverine any protections under the ESA. In so doing, FWS disregarded the best available scientific information and the recommendations of its own scientists, made numerous analytical errors, and ultimately violated the ESA."
At the Center for Biological Diversity, endangered species director Noah Greenwald said Ms. Walsh's decision is "yet another unfortunate example of politics entering into what should be a purely scientific decision. All of the science and the agency's own scientists say the wolverine is severely endangered by loss of spring snowpack caused by climate change, yet the agency denied protection anyway.'
"The best available science shows climate change will significantly reduce available wolverine habitat over the next century, and imperil the species,' said Jackson Hole Conservation Alliance's Siva Sundaresan. 'As an agency responsible for protecting our wildlife, FWS should not ignore science and should make their decisions based on facts and data.'
"One of the most important things that we can do to get wolverines on the road to recovery in the face of a warming climate is to get them back on the ground in mountain ranges where they once lived,' said Megan Mueller, senior conservation biologist with Rocky Mountain Wild. 'We are disappointed by the Service's decision not to list wolverines under the Endangered Species Act as protections would have helped to facilitate such efforts in Colorado and beyond.'
'The remote, rugged, and snowy North Cascades are ideal wolverine habitat,' said Dave Werntz, Science and Conservation Director with Conservation Northwest. 'Protection under the Endangered Species Act will help wolverine survive a warming climate, shrinking snowpack, and increasingly fragmented habitat.'

"Best available science" has become a joke. Climate Change alarmists are losing ground and that is a good thing. Ms Walsh deserves an award for not falling to faux Climate Change agenda. We need more agency people willing to stand up against this politically fabricated hoax.
beachdumb,
The lawsuit cites McKelvey et al. (2011); Aubrey et al. (2009), (2007); Copeland et al. (2010); and Inman et al. (2013). In your review of the literature, which articles dispute this research?

You can't argue with the intentional ignorance of the climate change deniers.
These guys based thier research on flawed and manipulated climate data. The malfeasance of NCAR, NASA and IPCC is staggering.
You have to be intentionally ignorant to not question why the alarmist predictions are all based on manipulated data. But I guess many are just naive and gulliable.

All of those studies are now flawed, prediction models are wrong and not based on real climate data. It's a huge blow to the scientific community, they are losing credibility. Walsh is probably smart enough to realize this and not willing to go along with the cherade.
Direct from the black helicopters, no doubt, here are the credentials of your link:

Now, back to wolverines?
I'm sure beachdumbs experience in the Northern Rockies is vast. So he's seen the evidence that glaciers are expanding in the region, and that areas that used to be "permanent snow fields" are becoming more permanent from year to year, instead of dissappearing. Yeah right. So, let's spend an entire 20 hours debating some southeastern tea partier about the rights of wolverines to exist in the northern rockies by protecting their most critical habitat.
