The Oregon Department of Fish and Wildlife says a calf found two weeks ago along the Imnaha River died from injuries inflicted by a wolf from the Snake River pack.
Rancher Charlie Warnock told The Observer newspaper that Fish and Wildlife has been emailing him updates on the whereabouts of collared members of the Snake River pack. Typically ranchers are contacted by text messages, but Warnock lives in a remote area without cell coverage.
The pack's territory is running close to the Imnaha pack, which has been involved in dozens of livestock losses and injuries since 2010.
The calf's death is the first confirmed cattle loss to the Snake River pack. Once there are four confirmed losses in six-month period, the state can kill members of the pack to prevent livestock attacks.
