On Monday, Dec. 18, Colorado Parks and Wildlife (CPW) experts released five gray wolves onto public land in Grand County.
The gray wolves were captured in Oregon where CPW veterinarians and biologists evaluated them to determine if they were fit for relocation to Colorado. Criteria for release included the age, sex, health and body condition of each animal.
Each gray wolf was weighed and measured. Staff collected genetic material — tissue and blood samples — before fitting each with a GPS satellite collar for tracking upon release by CPW staff. Then, the wolves were given vaccines and were placed in crates and flown to Colorado for release back into the wild.
CPW will repeat the process until at least 10 – 15 wolves have been reintroduced in Colorado by mid-March 2024. As outlined in the Colorado Wolf Restoration and Management Plan, CPW hopes to release 30 to 50 wolves over the next 3-5 years using wolves captured from nearby northern Rockies states from several different packs by trapping and darting them in the winter.
Gray wolves are listed both state and federally as an endangered species in Colorado by the U.S. Fish and Wildlife Service (USFWS). The U.S. Fish and Wildlife Service has designated the Colorado wolf population as Experimental under Section 10(j) of the Endangered Species Act. This provides management flexibility that would otherwise be prohibited.
Colorado Governor Jared Polis said, “I am proud of the Colorado Parks and Wildlife staff for their hard work to make this happen.”
“This is a historic day for Colorado,” said CPW Director Jeff Davis. “We want to thank the U.S. Fish and Wildlife Service for their work to complete and approve the 10(j) designation that lists wolves in Colorado as a nonessential, experimental population. This helps us to follow all of the conflict mitigation plans we accounted for in the final Colorado Wolf Restoration and Management Plan.”
