Washington Fish and Wildlife Director Kelly Susewind has decided against taking another crack at culling the Couse wolf pack in southeast Washington in response to a predation that likely happened weeks ago.

Fish and Wildlife found an injured calf Oct. 13 in an area shared by the Couse and Tucannon packs in Asotin County. Investigators estimated the injuries were at least two weeks old.

The department said it was unsure which pack attacked the pack. Also, the department says killing a wolf more than two weeks after a predation doesn’t teach the rest of the pack to stay away from livestock.

“Due to the age of the injuries, the effective period for lethal removal has already passed,” the department stated in a press release Monday.

The Couse pack killed at least one calf and injured two calves and a cow and between late June and mid-September. In response, Susewind authorized removing one or two wolves on Sept. 24.

The order expired two weeks later on Oct. 8 without the department killing a wolf, or the pack attacking more cattle.

Fish and Wildlife considered lethal control in mid-July, too. The department decided not to after an adult male wolf in the Couse pack was legally shot while chasing livestock July 8.
