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: As of October 8, 2010, >28 wolf packs have denned throughout Wyoming (including all national parks) 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): 17 BP = We estimate >31 packs in Wyoming (outside national parks) with 17 packs producing 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, Washakie, and Wiggins Fork).
YNP: 9 BP = 13 documented packs with 9 packs producing pups (Agate, Black
Tail, Canon, Cougar, Delta, Lamar, Madison, Molly, and Quadrant).
GTNP: 2 BP = 2 documented packs with 1 pack producing pups (Phantom Springs), plus 1 pack that is suspected to have denned (Huckleberry).
Table 1. Total wolf mortality in Wyoming (outside YNP) from 2003-2010.
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 10/10/10, WY Wildlife Services confirmed that 1 calf had been killed by wolves from the Sunlight Pack on a grazing allotment west of Cody, WY. The Sunlight Pack consists of > 12 wolves and has recently been involved in another cattle depredation earlier this fall. The USFWS requested Wildlife Services to remove 3-4 wolves.
Table 2. Confirmed livestock depredations and control actions in WY from 2003 - 2010.
*One foal was killed by wolves (recorded as confirmed), 2 horses were chased by wolves and injured when they were run through a fence (recorded as 1 confirmed and 1 probable), and 1 horse was chased by wolves and broke its leg when it was run over a cattle guard (recorded as probable). All 3 injured horses had to be euthanized.
** In addition to 22 confirmed cattle depredations (losses), 1 dead calf was recorded as a probable wolf-kill, and 7 calves & 1 steer were also injured by wolves.
Figure 1. Annual wolf population size and the number of cattle and sheep losses per year in Wyoming (outside YNP) from 2000-2010. Preliminary population estimates and livestock depredations counts for 2010 were recorded as of October 15, 2010. All additional livestock losses due to wolf depredations occurring between October 16, 2010 and December 31, 2010 will be reported in our Weekly Reports and our 2010 Annual Report.
Figure 2. Annual number of wolf packs in Wyoming (outside YNP) and the number of wolf packs that are involved in at least 1 livestock depredation per given year. The following 13 packs have been involved in > 1 livestock depredation in 2010: Sunlight, Rim, Lava Mountain, Wiggins Fork, Black Butte, Pacific Creek, Clark, Dempsy Basin, Dog Creek, Hoodoo, Green River, Absaroka, and East Fork.

On the 14th, Bangs was part a tour for the annual meeting of the Society of Environmental Journalists 'Preserving Wildlife in a Changing World'. Talks on elk, bear, highway crossings, wolves, lynx, snowshoe hare, and working dogs for conservation were presented during the day long field trip. About 50 people attended.
