MONITORING
Information about wolves in the NRM DPS (Idaho, eastern Oregon, Montana, north central Utah, eastern Washington, and Wyoming) will be published in the 2011 NRM Interagency Annual Wolf Report which will be available in early March 2012. Ongoing updates for these states include:

Idaho: As of December 30, 173 wolves were harvested by hunters and 24 wolves were taken by trappers. Hunting season is scheduled to close in 2 wolf zones (Beaverhead and Island Park) on December 31. The remaining wolf hunting zones are scheduled to close on March 31, with the exception of 2 zones (Lolo and Selway) closing on June 30. Trapping season (5 wolf zones) is scheduled to close on March 31.

Montana: As of December 30, 120 wolves were harvested. The wolf hunting season was extended to February 15 or until the quota is met, whichever comes first.

Oregon: The Oregon Wolf Conservation and Management Plan was adopted in 2005 and updated in 2010. At least 5 packs exist in the eastern portion of the state within the NRM DPS and >2 wolves have dispersed west outside of the DPS.

Washington: The Washington Fish and Game Commission approved a final wolf conservation and management plan in December 2011. At least 3 packs exist in the eastern portion of the state in the NRM DPS and >2 packs exist in the federally listed western portion of the state.

Utah: No wolf packs were documented in Utah in 2011.
 
Wyoming (outside YNP)
In 2011, Wyoming had > 37 packs including > 23 breeding pairs in Wyoming (outside YNP) (Figure 1).

Minimum number of wolf packs and breeding pairs: 1999-2011
