Tehama County has documented its first recorded wolf-caused livestock death in 2026. County supervisors confirmed the finding after receiving Agricultural Commissioner Thomas Moss's report.
A wolf depredation is an injury or death investigators attribute to a wolf. The confirmed attack occurred in eastern Tehama County, within the Ice Cave pack's range, according to the Appeal-Democrat's Sept. 3 report.

What is confirmed—and what remains unknown
Moss said DNA results returned quickly enough to identify wolves. The available reporting does not identify the livestock species, the number of animals involved, the ranch or the exact date. Those gaps matter.
The case establishes that a wolf-caused livestock death occurred in the county, but it does not support assumptions about the size or circumstances of the loss. It also should not be confused with a March 23 case involving a dead steer in western Tehama County. The California Department of Fish and Wildlife's report, updated Aug. 10, classified that earlier case as "Non-Depredation.".
How investigators determine wolf depredation
CDFW investigators examine carcass injuries and evidence at the scene. They may also consider genetic findings and available wolf GPS information. DNA can establish that wolves were present, but genetic evidence alone does not prove that a wolf caused an animal's death.

Investigators must evaluate the evidence together before assigning a determination. The state's publicly posted 2026 depredation report predates the newly confirmed event. Readers should therefore expect a delay before the Tehama case appears with fuller determination details.
Why the Ice Cave pack is relevant
The Ice Cave pack ranges across eastern Tehama and northwestern plumas counties. CDFW's 2025 annual wolf report documented at least six pups in the pack that year. That range information explains why investigators would consider the pack when reviewing an eastern Tehama loss.
It does not, by itself, establish which wolf or wolves were involved. The confirmed case gives Tehama livestock producers a documented local example of depredation. It does not establish how frequently such attacks will occur or whether other unexplained livestock deaths involved wolves.
What the affected producer can do
The producer may seek state direct-loss compensation if CDFW classifies the loss as confirmed or probable wolf depredation. CDFW accepts applications for qualifying losses that occurred on or after July 1, 2024, according to the department's wolf compensation program page. The key practical checks are: Until CDFW updates that report, the livestock species, number lost, ranch and exact kill date remain unconfirmed publicly.
- Confirm that CDFW classified the incident as confirmed or probable.
- Verify that the loss occurred on or after July 1, 2024.
- Review CDFW's application requirements for direct-loss compensation.
- Monitor the state depredation report for the incident entry and added details.
