MONITORING

Utah: No wolf packs were documented in Utah in 2011; however, in early March 2012, several sightings of wolves were reported near Provo, Utah. On March 9th, the Utah Department of Natural Resources attempted to locate and capture wolves in the area using a helicopter. The capture crew followed tracks of 4-5 wolves but we unable to locate or capture them. State biologists will attempt to locate wolves again if continued sighting are reported.

Radio-collaring in Wyoming:  Winter capture and radio collaring efforts (using both GPS and VHF collars) were completed in YNP last month and are ongoing in other regions of WY through the end of March.
