Delisting Litigation Status
Oral arguments are scheduled in federal court in Cheyenne, WY on January 29 to address the state of Wyoming’s request to delist wolves in Wyoming.

A hearing on the preliminary injunction request was held in Federal Court in Missoula, MT on August 31. Oral arguments were heard from the plaintiffs, U.S. Department of Interior, Montana, and Idaho. On September 8, the Federal Court denied the preliminary injunction motion filed by Defenders of Wildlife and others to stop the 2009 regulated gray wolf hunts in Idaho and Montana.  However, in issuing his order, the judge indicated that his preliminary review of the overall delisting case raised questions about Service’s approach of conferring ESA protections to a “significant portion of the range” of a species, as opposed to designating the entire species as a threatened or endangered species. A hearing date for oral arguments has not been set, but is expected to be soon after legal briefs are completed in late January 2010. 

For 2009, Wyoming had >319 wolves in >44 packs (>27 breeding pairs). Wyoming (outside Yellowstone National Park) had >223 wolves in >30 packs (>21 breeding pairs).Yellowstone National Park estimates >96 wolves in 14 packs (6 breeding pairs).

On January 16 and 17, the USFWS wolf crew in Jackson  aerial darted and radio collared 12 wolves in 4 packs in the Jackson area.

On January 1, 2, and 3rd, 9 wolves in 4 packs in the Sunlight Basin drainage were captured and radio collared by Quick Silver Air. Arthur Middleton (PhD graduate student from the University of Wyoming) and Abby Nelson (MS graduate student from the University of Wyoming) assisted in the capture and radio collaring. Wolves were fitted with 6 GPS collars and 3 VHF collars.

Idaho: Wolf hunting season is still open in parts of Idaho with a statewide quota of 220 wolves. The Idaho Fish and Game Commission extended the wolf hunting season until March 31 in units where quotas have not been reached. For the most current harvest status information, call 1(877)872-3190.

Nothing to report at this time.

On January 4, the USFWS and Grand Teton National Park began a collaborative research effort to monitor winter predation by wolves in Grand Teton National Park and the adjacent national forest. Two crews of volunteers (3 members/crew) are back tracking wolves to determine prey selection and predation patterns on elk and moose using native winter range.
