Litigation: On January 28, 2011, the Missoula Federal District Court (Defenders of Wildlife et al v. Hall et al, 9:08-cv-00014-DWM) issued an order that vacated the February 4, 2010 oral arguments in a case over a provision of the 2008 experimental rules that allowed states and tribes to remove wolves in areas where wolf predation was having an unacceptable impact on a ungulate herd.  The court also ordered the Government and environmental Plaintiffs to supply information to the court showing why the court has any further jurisdiction in the case because there might not be a valid 10(j) rule.  The Court asked for information whether a 10(j) area could still exist since the experimental population wolves and the endangered wolves population now mix and interbreed.  Briefs were sent to the Court on February 22, 2011.

On 2/26/11, the USFWS captured and radio collared 5 wolves (in 2 packs) in the Jackson area and will continue capture/collaring efforts throughout the NW portion of the state during early March.
