Wyoming: The Wyoming court ruled on November 18, 2010 in the case State of Wyoming v. U.S. Department of the Interior 09-cv-118. In this case, the State of Wyoming, et al., filed suit challenging the USFWS 2009 regulation removing ESA protections for the NRM DPS of the gray wolf, except in Wyoming. The USFWS determined that NRM wolves should remain listed in Wyoming because it determined that Wyoming’s regulatory mechanisms were insufficient. Judge Johnson remanded the 2009 delisting rule back to the USFWS for reconsideration. He ruled that USFWS’s determination “that Wyoming must adopt a state-wide trophy game management area" was not supported by the administrative record. The Court remanded the rule back to the agency to reconsider whether Wyoming’s existing management framework is sufficient to warrant delisting under the ESA.
Wyoming: At least 19 wolf packs have denned throughout Wyoming (outside YNP) in 2010. Figures 1-2 and Table 1 display preliminary population data recorded as of November 19, 2010. All additional population data recorded between November 19 and December 31, 2010 will be reported in our Weekly Reports and our 2010 Annual Report.

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. Figures 2-5 and Table 2 display preliminary depredation and control data recorded as of November 19, 2010. All additional livestock losses due to wolf depredations occurring between November 19, 2010 and December 31, 2010 will be reported in our Weekly Reports and our 2010 Annual Report.
On 11/17/10, livestock depredation control was completed in Sunlight Basin, west of Cody, when Wildlife Services removed 2 wolves from the Absaroka Pack and 2 wolves from the Sunlight Pack. Both packs had been involved in recent repeated livestock depredations.

*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 29 confirmed cattle depredations (losses), 1 dead calf was recorded as a probable wolf-kill, and 7 calves & 1 steer were also injured by wolves.
