The Oregon Department of Fish and Wildlife has authorized the killing of up to two wolves from the Frazier Mountain pack in Baker and Union counties after wolves from the pack repeatedly attacked cattle.

A rancher requested the kill permit after four attacks on cattle since early November.

According to ODFW investigations, wolves from the pack have killed one calf and three cows, and injured a yearling cow, since Nov. 1.

Four of the depredations happened on private land north of Keating Valley.

One happened on private land in the Pyles Canyon area south of Union.

The permit allows the rancher or agent, including the federal agency USDA Wildlife Services, to kill up to two wolves on pasture land the rancher owns or leases.

The permit is valid until Jan. 31, 2024, or until two wolves are killed, whichever happens first.

According to ODFW, the rancher has tried nonlethal methods to deter wolves, including increased human presence, hazing of wolves, and moving cattle to other pastures.

The Frazier Mountain pack consists at least five wolves, including one juvenile, according to ODFW. The pack is named for the area it is known to roam, including Frazier Mountain, in southern Union County between Union and Medical Springs.
