Colorado Parks and Wildlife confirmed a fourth gray wolf livestock attack in Grand County on Sunday, according to the agency’s list of confirmed gray wolf depredations.

Local CPW staff conducted a field investigation and found injuries on one dead yearling calf consistent with wolf depredation, according to an email from CPW. The incident occurred on the same property as previous depredations on April 17 and 18. Claims for the three separate incidents have not been submitted.

Sunday’s incident is the fourth confirmed gray wolf depredation in Grand County in April and the sixth separate depredation incident since 10 gray wolves were released in Colorado in December 2023.

Colorado’s first confirmed wolf depredation after the release occurred on April 2 in Grand County. The second attack happened five days later and 60 miles north in Jackson County.

The Middle Park Stockgrowers Board requested that CPW officials lethally remove two wolves suspected in the livestock attacks Tuesday. However, officials stated that one wolf suspected in recent depredations is likely “denning” and in the breeding process. Removing the male wolf “would be irresponsible management and potentially cause the den to fail, possibly resulting in the death of the presumed pups,” CPW Director Jeff Davis said in a letter to the board Tuesday.

Amid reports of livestock depredation, one of the 10 gray wolves reintroduced to Colorado was found dead in Larimer County on April 18. Initial evidence shows the wolf likely died of natural causes, officials said Tuesday.

The approach to lethal removals will likely become more liberal as the wolf population in Colorado grows, according to Davis.
