Just months after being released as part of Colorado’s high-profile wolf reintroduction program, one of the transplanted gray wolves was killed in Wyoming. Wildlife officials shot the animal after confirming it had attacked and killed livestock on private land.
The male wolf, which was fitted with a collar from Colorado Parks and Wildlife (CPW), was discovered near five dead sheep in north-central Wyoming. Investigators from the U.S. Department of Agriculture’s Wildlife Services found tracks, signs of a struggle, and bite wounds that were consistent with a wolf attack. Because Wyoming classifies wolves as predators in most of the state, officials may lethally remove them when they threaten livestock.
Two States, Two Systems

This fatal encounter highlights a key tension between state policies. Colorado has designated gray wolves as a protected species under its voter-approved reintroduction program. However, the wolf had crossed into Wyoming, where protections are far less strict.
This difference illustrates the fragmented nature of wildlife policy in the West. Conservationists have called for more unified, science-based management across state lines. At the same time, many ranchers and rural residents are demanding stronger protections for their livestock and property.
CPW released the following statement relating to the event:
“CPW biologists received a mortality alert for male gray wolf 2505-BC this past weekend, March 16. The agency has confirmed the mortality took place in north-central Wyoming. 2505-BC was part of the group of wolves translocated to Colorado from British Columbia and came from areas where there is no overlap between wolves and livestock…”
