Litigation Status
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: Oral arguments were heard in federal court in Missoula, MT. on June 15. The court will address the 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. Judge Malloy said he would issue a decision as soon as possible. 

Monitoring: At least 12 packs have denned this spring in Wyoming (outside YNP), including: Absaroka, Beartooth, Buffalo, Chagrin River, Elk Fork Creek, Green River, Hoodoo, Pacific Creek, Phantom Springs, Pinnacle Peak, Sunlight, and Owl Creek.

Control
Wyoming:
On 6/9/10, USFWS examined a US Forest Service horse with a broken leg. The horse had to be euthanized. Based on the investigation, it was determined that the horse was injured when a wolf(s) chased the horse over a cattle guard. The incident was recorded as a probable wolf depredation, but no control action was taken at that time. On 6/18/10, the USFS reported another horse injured in the same area. The horse was taken to a vet and will survive injuries sustained at the cattle guard. USFWS and USFS personnel inspected the area, but could not find evidence of wolves at the site. To minimize future problems, the USFS will install a gate to keep horses away from the cattle guard.

On 6/19/10, WY Wildlife Services confirmed a lamb killed by wolves near Dempsey Creek, northwest of Kemmerer, WY. Remains of additional dead sheep were found, but the cause of death could not be confirmed. At the request of the USFWS, Wildlife Services removed an old adult male wolf. On 6/20/10, Wildlife Services removed an adult female wolf and 6 pups.

On 6/9/10 and 6/13/10, WY Wildlife Services confirmed 2 calves were killed on private land by a new pack of wolves west of Cody, WY.  At the request of the USFWS, Wildlife Services removed two adult wolves at the depredation sites on 6/10/10 and 6/14/10. On 6/18/10, an adult male was radio collared. On 6/23/10, Wildlife Services removed 2 adults and 4 pups wolves after wolves from this new pack killed a 3rd calf on the same private property on 6/21/10.
