Colorado Wolf Update w/Mortality

General Areas Inhabited by Gray Wolves in Colorado – April 2025 Update

The April 2025 Collared Gray Wolf Activity Map is now live, which shows where wolves moved around the state this month. For a watershed to indicate wolf activity, at least one GPS point from at least one wolf collar was recorded within the boundaries of the watershed within the last 30 days.
 

Wolf Movement Updates:

• CPW biologists received a mortality alert for female gray wolf 2514-BC. CPW, in cooperation with the National Park Service, has confirmed that the mortality took place in Rocky Mountain National Park. As a federally listed species under the Endangered Species Act, the U.S. Fish and Wildlife Service is investigating. A final determination of the cause of death will not be made until the investigation is completed. 2514-BC was part of the group of wolves translocated to Colorado from British Columbia. 
• A female wolf (separate from the wolf in RMNP), released in Colorado in January after being translocated from British Columbia, has made significant movements across the state, covering more than 1,230 miles since translocation — an extraordinary display of the species’ natural exploratory behavior. This single wolf’s movement lit up nearly the entire southern line of watersheds on the map.
• Recent data shows activity in watersheds west of major population centers like Denver, Boulder and Estes Park due to the movement of other collared gray wolves. While these areas lit up due to brief movement on the western fringes of these watersheds, it does not mean that wolves were or are currently in high human-density areas.
• Wolves continue to make broad movements across many western counties (see map). Wolves travel long distances to find food, mates and space to live.
• CPW has an agreement with Utah, New Mexico and Arizona to ensure wolves crossing into those states can be safely returned to Colorado.
