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. Oral arguments will be heard on June 15, 2010 in Missoula, MT.

Nothing to report at this time.

Wyoming: On 6/2/10, a horse was severely injured (and later euthanized) when it ran through a fence near Bondurant.  WY Wildlife Services examined a horse and concluded that the horse had been chased through a corral fence by > 1wolf. The owner was offered a Shoot-on-Sight permit, but declined. W.S. will set traps and attempt to remove the offending wolf (or wolves).

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.

*One foal was killed by wolves, 2 horses were chased by wolves and injured when they were run through a fence, and 1 horse was chased by wolves and broke its leg when it was run over a cattle guard. All 3 injured horses had to be euthanized.

As of June 10th, there have been six confirmed livestock depredations - all on private land - attributed to the Imnaha Pack in Wallowa County east of Enterprise, Oregon.  On May 31, ODFW authorized Wildlife Services to kill two uncollared wolves implicated in the livestock losses.  To date, no wolves have been killed.  On June 9th, ODFW extended the WS authorization to June 18th and expanded the area where WS may conduct control activities to 15 square miles (still limited to private pasturelands).
