Litigation: On March 24, 2011, the Missoula Federal District Court heard oral arguments on a settlement agreement between environmental groups and the Service, and whether a 10(j) area could still exist since the experimental population wolves and the endangered wolves population now mix and interbreed. A decision is pending.
On 3/18/11, the USFWS captured and radio collared 5 wolves (in 3 packs) in the Cody area. The YNP wolf project collared 2 wolves in YNP on 3/18/11.
