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.
Northern Rocky Mountains: The U.S. Federal District Court in Missoula, Montana, issued an order on August 5, 2010, in Defenders of Wildlife et al. v. Salazar, CV 09-77-M-DWM and Greater Yellowstone Coalition v. Salazar, CV 09-82-M-DWM, which vacated the delisting of the Northern Rocky Mountain (NRM) Distinct Population Segment (DPS) of the gray wolf. In compliance with this order, wolves are again considered endangered throughout the NRM DPS except where they are classified as experimental populations (southern Montana, Idaho south of Interstate 90, and all of Wyoming).
Wyoming: At least 25 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): 15 packs produced pups (Absaroka, Beartooth, Chagrin River, Dog Creek, East Fork, Elk Fork Creek, Greybull River, Green River, Hoodoo, Lava Mountain, Pacific Creek, Pinnacle Peak, South Fork, Sunlight, Owl Creek, and Wiggins Fork), plus 2 packs that are suspected to have denned (Rim and Washakie).
GTNP: 1 pack produced pups (Phantom Springs), plus 1 pack that is suspected to have denned (Huckleberry).
YNP: 9 packs produced pups out of 13 documented packs.

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.
Sublette County: WY Wildlife Services confirmed that wolves from the Green River Pack killed 1 calf on 8/14/10, 2 calves on 8/15/10, and 1 calf on 8/17/10 in the Upper Green River drainage. The pack killed 2 additional calves earlier this summer. Wildlife Services is attempting to trap and radio collar > 1 wolf. Control actions are ongoing to remove 3-4 wolves from the pack.
On 8/19/10, WGFD confirmed that a single wolf killed a yearling steer near Bondurant, WY.
Fremont County: WY Wildlife Services confirmed that wolves from the East Fork Pack killed 1 calf on 8/8/10, 1 calf on 8/14/10 and an adult cow on 8/15/10. On 8/20/10, Wildlife Services captured and radio collared an adult male and an adult female wolf. Control actions are ongoing to remove 2 wolves from the pack.

All 3 injured horses had to be euthanized.
