Litigation Status
Northern Rocky Mountains- Montana Federal Court relists wolves-  Yesterday August 5, 2010 Judge Malloy filed his ruling in the Northern Rocky Mountain wolf delisting case, vacating our rule and putting wolves back on the list as endangered.  

The ruling states, in part, that the Endangered Species Act "does not allow the U.S. Fish & Wildlife Service to list only part of a "species" as endangered, or to protect a listed distinct population segment only in part...and the legislative history of the Endangered Species Act does not support the Service's new interpretation of the phrase "significant portion of its range."  To the contrary it supports the historical view that the Service has always held, the Endangered Species Act does not allow a distinct population segment to be subdivided.  Accordingly, the rule delisting the gray wolf must be set aside because, though it may be a pragmatic solution to a difficult biological issue, it is not a legal one. "

DOI issued a statement yesterday and remains the primary spokesperson on this issue.   The statement is on  For further questions call Sharon Rose in Denver, CO at 303-236-4580. 

Wyoming: Oral arguments were heard in federal court in Cheyenne, WY on January 29 to address the state of Wyoming’s request that the USFWS accept the Wyoming Wolf Management Plan. A decision from Judge Allen Johnson is pending.

Wyoming: At least 23 wolf packs have denned in Wyoming in 2010. We anticipate more breeding pairs will be identified this summer as additional den/rendezvous sites are located and reproduction is confirmed. Reproducing packs in Wyoming, Yellowstone National Park (YNP), and Grand Teton National Park (GTNP) include:

Wyoming (outside national parks): 14 packs produced pups (Absaroka, Beartooth, Chagrin River, East Fork, Elk Fork Creek, Greybull River, Green River, Hoodoo, Pacific Creek, Pinnacle Peak, South Fork, Sunlight, Owl Creek, and Wiggins Fork), plus 2 packs that are suspected to have denned (Rim and Washakie).

YNP: 8 packs produced pups (Black Tail, Agate, Lamar, Silver, Molly, Delta, Madison, and Canyon), plus 2 packs that are suspected to have denned (Cougar and Quadrant).

GTNP: 1 pack produced pups (Phantom Springs), plus 1 pack that is suspected to have denned (Huckleberry).

Wyoming: We continue to manage wolf population growth and wolf distribution to minimize chronic loss of livestock from wolves and promote wolf conservation by maintaining the Wyoming wolf population well above recovery objectives.
Park County: On 7/26/10, WY Wildlife Services confirmed a calf was injured by wolves on private property west of Cody, WY.

Teton County: Wolves from the Buffalo Pack were suspected of killing a border collie herding dog in the Gros Ventre drainage, SW of Jackson.
