CPW says chronic‑depredation policy triggered lethal removal after Pitkin County livestock losses

Colorado Parks and Wildlife officials briefed Pitkin County commissioners on July 1 about wolf reintroduction and management after a series of livestock depredations earlier this year led the agency to lethally remove one wolf under an administrative directive addressing chronic depredation.

The briefing provided a state‑level policy context and local detail: CPW described how reintroduction proceeded, how depredations were investigated, what the chronic‑depredation trigger requires, and what tools the agency is using to reduce conflict while limiting lethal removals.

“Administrative directive for us is just it's just a piece of information. It's a document that helps staff stay line outlined with what we're supposed to do,” Matt Yamashita, area wildlife manager for Colorado Parks and Wildlife out of Glenwood Springs, said. Yamashita described the agency’s chronic‑depredation directive and the operational threshold it sets: three depredation events in a 30‑day period, at least one of which must be clear and convincing evidence that wolves were the cause. The directive authorizes, but does not mandate, lethal removal when chronic depredation is demonstrated.

CPW staff said reintroduction in Colorado began with releases in December 2023 and continued in January 2025; some animals were translocated from Oregon and others from British Columbia. The agency reported that 15 animals arrived in January 2025 and that some packs were later released into Pitkin and Eagle counties.

CPW investigators confirmed depredations on livestock in February 2025 and again in May 2025. “This directive told us that if 3 depredation events occur in a 30 day period, 1 of which has to be clear and convincing that wolves were the culprit, that that triggers chronic depredation and would, otherwise warrant lethal removal of an animal,” Yamashita said. After a site analysis and collar data review, staff removed one yearling male they identified as a likely participant in at least one confirmed depredation.

The agency emphasized it is assessing whether that removal changed the pack’s behavior and said it is trying to avoid further lethal removals. CPW has been deploying nonlethal tools including range riders, flagging fencing, flashing “fox lights,” noise devices and increased on‑the‑ground monitoring. CPW staff also described financial remedies available to producers: confirmed killed animals are eligible for compensation, and the agency is implementing mechanisms to address indirect losses such as presumed missing animals and declines in pregnancy and weaning weights when producers can document a historical baseline.

Commissioners asked about acceptable loss rates and about whether Pitkin County’s experience differs from other counties. CPW said the initial threshold of acceptable losses is still being established and that local packs — in some cases multi‑generation groups rather than newly forming pairs — can behave differently. CPW said its harvest indices and field observations provide mixed signals: some indicators suggest populations are stabilizing while the abundance of sows with multiple cubs suggests healthy reproduction in parts of the region.

Ending: CPW asked for continued local collaboration on site assessments, deterrents and compensation administration while the agency monitors the pack and evaluates whether additional removals are necessary.
