A wolf killed a calf in north-central Colorado this week, but wildlife officials wouldn’t say whether the animal responsible was one of the 10 released in December as part of the state’s reintroduction effort.
The kill, discovered Tuesday in Grand County and confirmed Wednesday, was the first verified predation of livestock since the state released wolves late last year as part of its voter-mandated reintroduction of the species. Colorado had other wolves before the reintroduction, with two wolves remaining from a pack created by animals that migrated from Wyoming.
The risk of wolves preying on livestock fueled strong opposition by ranchers to the reintroduction, which found most of its support from urban voters.
A news release from Colorado Parks and Wildlife did not say if the wolf was one of the reintroduced animals or was one of the more-established wolves. In response to a follow-up question from The Denver Post, CPW spokesman Travis Duncan said: “CPW is not identifying which wolves were involved in this incident.”
Duncan also would not say how many wolves were involved in the kill.
The calf carcass had teeth marks on its hindquarters and neck and hemorrhaging under its hide, all of which are consistent with a wolf attack, CPW Area Wildlife Manager Jeromy Huntington said in the release.
Investigators also found wolf tracks nearby.
Wildlife officials believe there are 12 wolves in Colorado: the 10 introduced in December and two from a pack that established itself in Jackson County after migrating from Wyoming. The wolves released in December were set loose in Grand County and neighboring Summit County.
All of the wolves have GPS collars that record the animals’ locations every four hours, though one collar stopped functioning in the last month.
The owner of the calf will be eligible for fair-market compensation through the state’s reimbursement program for kills and injuries to livestock caused by wolves. The calf’s owner was not identified.
Colorado Parks and Wildlife staff will continue to work with ranchers in the area and encourage the use of non-lethal deterrents, according to the news release.
