2009 Annual Report
The 2009 Interagency Annual Wolf (Canis lupus) Report for the NRM DPS in 2009 can be viewed on-line at http://westerngraywolf.fws.gov .  The Idaho and Montana state sections of the annual wolf report are also available on-line at the websites for Montana Fish, Wildlife and Parks http://fwp.mt.gov/wildthings/management/wolf/default.html and Idaho Department of Fish and Game http://fishandgame.idaho.gov/cms/wildlife/wolves.  The annual wolf report is composed of five Sections: 1) Montana; 2) Wyoming; 3) Idaho; 4) USFWS overview of dispersal, funding, litigation, and relevant publications; and 5) Tables and Figures of wolf population statistics and wolf depredations. 
                         
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
Wyoming: At least 14 packs have denned this spring in Wyoming (outside YNP), including: Absaroka, Beartooth, Chagrin River, East Fork, Elk Fork Creek, Greybull River, Green River, Hoodoo, Huckleberry, Pacific Creek, Phantom Springs, Pinnacle Peak, Sunlight, and Owl Creek.

Oregon: Images captured July 3, 2010 on a motion-triggered trail camera indicated the Imnaha Pack had at least four pups this year and mark the first visual confirmation of wolf pups in Oregon for 2010. While the alpha female was seen in some of the images taken, the alpha male was not. The alpha male’s GPS collar has not been detected since May 31 and his fate and that of the collar remains unknown. ODFW and Oregon State Police continue to investigate the whereabouts of this wolf. A full description of events concerning wolves in Oregon can be viewed at:   www.dfw.state.or.us/wolves

 

Control
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 (outside YNP) well above recovery objectives.

On 7/15/10, Wyoming Wildlife Services confirmed that 1-2 wolves killed a total of 14 lambs and 1 ewe on public land in the Big Horn Mountains, approx. 15 miles south of the Wyoming/Montana state border. Four additional lambs were injured and are not expected to survive. The depredations first occurred on 7/12/10, with additional depredations occurring on 7/13/10. The USFWS requested Wildlife Services to remove the offending wolves. Last year, 3 wolves killed >113 sheep in the Big Horn Mountains before the depredating wolves could be controlled.

*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.
