A series of wolf attacks over the Memorial Day weekend left two calves dead and several others injured, according to the Colorado Cattlemen's Association.
The incidents occurred at the Lost Marbles Ranch, Crystal River Ranch, and McCabe Ranch in the Aspen-Snowmass area.
The attack at the Lost Marbles Ranch was carried out in broad daylight by a trio of wolves from the Copper Creek pack, the first group of gray wolves released into the wild as part of the state's reintroduction program.
Several members of the Copper Creek Pack have already been relocated due to repeated attacks on livestock.
CCA Executive Director Erin Spaur stated that the attacks represent a "clear betrayal of the public trust" and called for CPW to remove the Copper Creek Pack in compliance with the state's Wolf Plan
