A northeast Washington wolf pack attacked two more calves, Fish and Wildlife confirmed Tuesday, potentially pushing the department to consider lethal control.
The Wedge pack injured one calf and killed another in a private pasture in Stevens County, a department spokeswoman said.
The pack inflicted fatal injuries on another calf on May 11, according to the department.
Department officials planned to meet Wednesday to discuss the department's response.
According to the department's lethal-removal protocol,Fish and Wildlife will consider shooting one or two wolves after three attacks on livestock within 30 days.
The department considers whether additional non-lethal steps could be take to prevent the attacks. The decision rests with Fish and Wildlife Director Kelly Susewind.
Fish and Wildlife killed seven wolves in the Wedge pack in 2012, leaving two surviving members. It was the first time the department had culled a pack since wolves began returning to Washington.
After a prolonged period of no confirmed attacks, the Wedge pack killed a cow in a private pasture last June, according to Fish and Wildlife.
The Wedge pack had three wolves at the end of 2019, according to Fish and Wildlife. One pack member was legally harvested last year by a tribal hunter.
