Washington wildlife officials have resumed hunting for a wolf pack in Ferry County after investigators determined wolves injured a calf and probably killed two others.

In what would be a first for the state, WDFW said it planned to lethally remove the entire Profanity Peak pack to stop depredations on livestock.

The department shot two of the pack’s 11 members Aug. 5 and planned to kill more, but suspended operations Aug. 18 after the hunt became increasingly difficult. The halt angered county commissioners, who passed a resolution Friday authorizing the sheriff to remove the rest of the pack.

Later Friday, WDFW announced it had confirmed at least one more attack and probably two.

Since mid-July, WDFW investigators have confirmed that the pack has killed or injured six cattle and probably killed five others.

State policy calls for WDFW to consider shooting wolves after four confirmed depredations in a year. Previously, WDFW planned to “partially remove” the pack, but now plans to remove the remaining four adults and five pups.

“The department is committed to wolf recovery, but we also have a shared responsibility to protect livestock from repeated depredations by wolves,” WDFW wolf policy coordinator Donny Martorello said in a written statement.

The state has twice shot wolves, in 2012 and 2014, to stop chronic depredations, culling but not eliminating packs in Stevens County.

Wildlife managers in a helicopter shot two adult females in the Profanity Peak pack, including the pack’s breeding female.

Martorello said removing the rest of the pack will be hard because the wolves are in rugged timberlands.

The state has 19 known wolf packs, with 15 of them concentrated in the northeastern corner of the state. Wolves are no longer federally protected in the eastern one-third of Washington state, but they are a state-protected species.

The state’s policy calls for wolves to be widely distributed throughout Washington. While wolves have become an increasing problem for ranchers in northeastern Washington, progress toward meeting statewide recovery goals has been slow.

WDFW counted 90 wolves at the end 2015.
