2009 Annual Report
The 2009 Interagency Annual Wolf (Canis lupus) Report for the NRM DPS in 2009 can be viewed on-line at .  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 and Idaho Department of Fish and Game  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: A hearing on the preliminary injunction request was held in Federal Court in Missoula, MT on August 31. Oral arguments were heard from the plaintiffs, U.S. Department of Interior, Montana, and Idaho. On September 8, the Federal Court denied the preliminary injunction motion filed by Defenders of Wildlife and others to stop the 2009 regulated gray wolf hunts in Idaho and Montana.  However, in issuing his order, the judge indicated that his preliminary review of the overall delisting case raised questions about 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. A hearing date for oral arguments has been set for June 15, 2010.  

FWP is taking applications to fill several volunteer positions to help FWP with wolf monitoring during the upcoming field season.  Volunteers investigate public and agency wolf reports and help with trapping efforts.  Volunteers are expected to get underway sometime in April and wrap up by June 30.  An extension past June 30 is possible but depends on funding availability.  Volunteers need not stay the whole time.  Learn more at:  Montana Fish, Wildlife & Parks: Gray Wolf Volunteer Opportunity
On 4/18/10, WY Wildlife Services confirmed a foal was killed by wolves and a yearling horse was injured by wolves NW of Pinedale, WY. The horse was later euthanized. This depredation was caused by 2 remaining wolves from the Black Butte Pack. On 3/10/10, WY Wildlife Services confirmed a calf killed by 3 wolves from the Black Butte Pack. Control efforts were completed when Wildlife Services removed 3 wolves from the Black Butte Pack. Due to this new depredation, control efforts are ongoing to remove the remaining wolves responsible for the horse depredations.

Outreach and Education  
Mike Jimenez (U.S. Fish and Wildlife Service) and Doug Smith (National Park Service) each gave presentations at the Varg-Symposiet in Valadalen, Sweden on April 13, 2010.  Approximately 400 European biologists and general public attended the conference.  The symposium was sponsored by the Swedish Environmental Protection Agency, Norwegian Directorate for Nature Management, World Wildlife Fund, and Sweden World Wildlife Fund. Mike Jimenez spoke about wolves and wolf management in the northern Rocky Mountains of the US. Doug Smith described population status of wolves in YNP, predator-prey relationships, and wolf management in YNP. 

Mike and Doug also gave presentations at the Grimso Wildlife Research Station at a session attended by students, biologists Olof Liberg, Hakan Sand, and several other Swedish and European biologists. Discussions continued about wolf population dynamics, wolf management, wolf human interactions, human habituated wolves, and potential wolf relocations from other Scandinavian countries to Sweden to improve genetic diversity in Swedish wolves.
