Update, Sept. 23: Colorado Parks and Wildlife has confirmed that wolves killed one cow and one calf in Grand County. The investigation began after the cattle were found on Sept. 9. The Middle Park Stockgrowers Association sent Parks and Wildlife officials a letter on Sept. 13, expressing concern that the agency’s wolf Depredation Report webpage had not been updated since July 28. The webpage currently reflects the Sept. 9 depredation.

Colorado Parks and Wildlife is investigating a possible wolf-livestock depredation in Grand County, which may have occurred after the relocation of the Copper Creek Pack.

Local ranchers believe three calves were killed, after the relocation of two adult wolves and their four pups earlier this September. The dead animals were found the morning of Sept. 9.

“CPW (Colorado Parks and Wildlife) has received a report of a possible wolf depredation in Grand County. Local staff are conducting a field investigation,” agency officials stated Tuesday, Sept. 10.

If confirmed, staff will update the Gray Wolf Depredation Report webpage. 

Parks and Wildlife completed the operation to capture all six wolves from the Copper Creek Pack on Sept. 5. Following the wolves’ capture, the pack’s adult male died from injuries unrelated to the relocation, according to officials.

State officials are holding the female and four pups in captivity before making any decisions about releasing them back into the wild. 

The adult male of the Copper Creek Pack was believed to be responsible for multiple livestock killings in Grand County, as well as the adult female.
