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. 

MONITORING
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.

CONTROL
Wyoming: In March 2011, wolves in Wyoming killed 1 calf on private property. Two wolves were removed.

On 3/22/11, a horse broke its leg and had to be euthanized after being chased by wolves in a pasture on private property. A Shoot-on-Sight permit was issued to the owner. During the next 2 evenings, the wolves returned to the ranch and continued to chase horses. One wolf was killed in the horse pasture on 3/25/11.
