Delisting Litigation Status
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 not been set, but is expected to be soon after legal briefs are completed in late January 2010. 

Official wolf population estimates for Wyoming will be published in the Annual Report. As of November 2009, preliminary estimates for Wyoming outside Yellowstone National Park (YNP) are >200 wolves in >30 packs (19-21 breeding pairs).  Inside YNP there are approximately 104 wolves in 14 packs (6 breeding pairs).
