Colorado Parks and Wildlife has determined that a dead horse found about five miles south of Hayden was not a confirmed wolf depredation. The filly, owned by Kaitlynn Hayes Wood, was found in a pasture where no known wolves were present.
Why it matters
Confirmed wolf depredations trigger compensation considerations for ranchers, so the distinction between confirmed and unconfirmed losses matters for livestock owners across the state. The determination shows how wildlife officials weigh physical evidence and collar data when assessing wolf-related livestock deaths.
Investigators used on-scene evidence and collared wolf locations, placing the nearest collared wolves about 27 kilometers away from the horse's pasture. The cause of death remains unidentified in the publicly available information.
The players
Colorado Parks and Wildlife
Colorado Parks and Wildlife is the state agency responsible for managing wildlife, including the reintroduced gray wolf population, and for investigating livestock losses.
Kaitlynn Hayes Wood
Kaitlynn Hayes Wood is the owner of the filly found dead in a pasture south of Hayden.
The details
The filly was found dead in a pasture about five miles south of Hayden after being alive less than 24 hours earlier. CPW defines confirmed wolf depredation as physical trauma resulting in injury or death, and its investigation found the evidence did not meet that standard for this horse.
Timeline
September 2026: Seven calves, seven lambs, and one bull were confirmed killed by wolves in Grand County.
October 2026: Additional Grand County confirmed wolf kills were recorded during the month.
October 21, 2026: Two calves in Routt County were confirmed killed by wolves.
October 27, 2026: A second Routt County calf was confirmed killed by wolves.
November 5, 2026: CPW announced the Hayden horse investigation was not a confirmed wolf depredation.
Season Trajectory
Colorado's gray wolf reintroduction program has produced a steady series of confirmed livestock losses in Grand and Routt counties this fall. This investigation shows CPW applying its confirmed-depredation standard, which requires physical trauma, to separate wolf kills from other livestock deaths.
Ranchers who lose livestock to predators can report the loss to CPW for investigation. Owners should keep records of livestock deaths, including location and condition of the carcass, to support any future depredation review.
The takeaway
Confirmed wolf depredation requires physical evidence of trauma, so ranchers should document carcass condition and location promptly. Clear criteria help separate wolf-caused losses from other livestock deaths.
