Washington Wolf Population Continues To Increase

The recovery of Washington's wolf population continued in 2018 as numbers of individual wolves, packs, and successful breeding pairs reached their highest levels since wolves were virtually eliminated from the state in the 1930s.

Last week, the Washington Department of Fish and Wildlife published its annual year-end report, which shows the state has a minimum of 126 individual wolves, 27 packs, and 15 successful breeding pairs – male and female adults who have raised at least two pups that survived through the end of the year.

A year ago, those numbers were 122, 22, and 14, respectively.

In 2018, for the first time, WDFW documented the presence of a pack west of the Cascade Crest. A single male wolf in Skagit County, captured in 2017 and fitted with a radio collar, has been traveling with another wolf through the winter, thereby achieving pack status. Biologists chose the pack’s name – Diobsud Creek.

"We're pleased to see our state's wolf population continue to grow and begin to expand to the west side of the Cascades," said WDFW Director Kelly Susewind. "We will continue to work with the public to chart the future management of this important native species."

Information and survey findings are compiled from state, tribal, and federal wildlife specialists based on aerial surveys, remote cameras, wolf tracks, and signals from radio-collared wolves. As in past years, the annual count provides estimates of the minimum numbers of wolves in the state, because it is not possible to count every wolf.

Virtually eliminated from the state by the 1930s, Washington's gray wolf population has rebounded since 2008, when WDFW wildlife managers documented a resident pack in Okanogan County. Most packs occupy land in Ferry, Stevens, and Pend Oreille counties in the northeast corner of the state, but the survey revealed increasing numbers in Washington's southeast corner and the north-central region.

"Packs and breeding pairs are the building blocks of population growth," said Donny Martorello, WDFW wolf policy lead. 'It's reassuring to see our wolf population occupying more areas of the landscape."
