New Report on Wolverines in Greater Yellowstone

Wolverines in the Greater Yellowstone Ecosystem can really move, they need a lot of room to roam, there are not very many of them in the large areas where they roam, and they tend to live in areas at or above treeline.  These are just a few results from this intensive study of 30 wolverines monitored from 2000 to 2008. 

What do the authors recommend we do for wolverines? They call for a refined wolverine habitat map for the western United States to help inform a metapopulation conservation and management strategy.

Here are a few more

Wolverines and Climate Change Publication

Congratulations to Dr. Kevin McKelvey of the U.S. Forest Service Rocky Mountain Research Station and his eight co-authors for the publication of their study, “Climate change predicted to shift wolverine distributions, connectivity, and dispersal corridors.”

This study is important because it presents some of the best available information on the projected effects of climate change on wolverines in the western U.S.  Current wolverine habitat was modeled based on areas with persistent spring snow cover as described by Copeland et al. (2010)

Wolverines and Winter Recreation

The effects of winter recreation on wolverines is critical conservation question currently under study in central Idaho.  Winter 2009-2010 was the first year of the study, and researchers live-trapped and collared 3 adult male and 3 adult female wolverines.  All three of the females denned in February, and two of the three are thought to have had kits that survived through the denning season.  The researchers concurrently monitored snow-cat skiers, backcountry skiers/snowboarders, and snowmobile riders through four methods:  GPS tracking devices

Wolverines Jump to Front of ESA Candidate List

The U.S. Fish and Wildlife Service (FWS) announced a new ESA listing settlement in mid-July with the Center for Biological Diversity that includes a listing determination for the contiguous U.S. wolverine population by the end of Fiscal Year 2013.  Wolverines were excluded from an initial FWS listing workplan that was the outcome of a previous legal settlement with WildEarth Guardians announced this spring.  The 2013 deadline puts wolverines near the front of the FWS’s updated six-year listing workplan.  Once the judge has signed the

Wolverines Discovered in Northeastern Oregon

Photographs of two individual wolverines and tracks in the snow are some of the preliminary results from a new study that has confirmed the presence of wolverines in eastern Oregon.  The Wolverine Foundation is behind the project and describes it as follows: 

“This pilot study is focused on surveying for wolverines (Gulo gulo) in the Wallowa-Whitman National Forest within and adjacent to the Eagle Cap Wilderness using proven non-invasive detection methods for wolverines.”

Yellowstone Wolverine Study Completed

A final report was just released from a study of wolverines in the eastern portion of the Greater Yellowstone area (not to be confused with a complementary study of wolverines in the western GYA by Wildlife Conservation Society that is still ongoing).  The eastern GYA study documented the movements of seven wolverines from 2005 - 2009.  Some of its key findings include:  (1) wolverines are even rarer than expected in Greater Yellowstone, with many areas of suitable habitat vacant; and (2) Yellowstone’s wolverines have a low reproduction rate, large

Wolverine Study in Canada’s Rocky Mountain Parks

A new study aims to determine the status of wolverines in Canada’s world-famous Banff, Yoho and Kootenay national parks, while evaluating the effects of the TransCanada highway and other major developments on wolverine genetics and movements.  The study gained some immediate publicity when remote cameras captured several wolverines on film.  Using “non-invasive” methods—collecting wolverine photos and hairs by attracting them with beaver carcasses secured to trees—basic questions about wolverine presence, abundance and fine-scale genetic

Wolverine listing decision Dec 2010

ESA listing found “warranted, but precluded” for wolverines

In a revised status review announced on December 13, 2010, the U.S. Fish and Wildlife Service determined that wolverines warrant Endangered Species Act protections, but the listing is precluded by other priorities.  Wolverines were found to be threatened in the western U.S. due to their low numbers and the decline of areas with persistent spring snowpack.  The Fish and Wildlife Service assigned the wolverine a listing priority number of 6—on a scale of 1 to 12 where 1 is the highest

New video promotes The Wolverine Foundation

Produced by Conservation Media for The Wolverine Foundation, a new short film explores one of the most fascinating and least understood animals on the planet. This small, rare, and elusive creature may be able to kill a moose or fend a grizzly off a kill, but it faces serious threats such as climate change for which it is no match.

Chasing the Phantom

Wolverine:  Chasing the Phantom showing on PBS Nature this November

Here is a description of the film from PBS Nature and links to the trailer and to the producer's website...

"Through the heart of the frozen north, roams a creature with a mystique as old as the mountains -- and a reputation as big as all outdoors. . .

Wolverine.  The name conjures images of the wild, the savage – the untamable.  Legend paints it as a solitary killer who takes down prey as large as moose, crushing bones to powder with its powerful jaws. 

But there is another image of the
