Current numbers: 4
Pack status: Active. Designated in 2013.
The Tucannon Pack was designated in 2013.
On May 1, 2016, the Washington Department of Fish & Wildlife (WDFW) captured and radio collared the breeding female, WA058F, from the Tucannon Pack. Five days later, she was found dead by WDFW staff. It is believed she died from an infection related to her capture a few days beforehand. At the time, it was believed that the pack had pups 5-6 weeks old, and there were concerns expressed over their survival.
With the the death of WA058F, there were no radio-collared wolves in the Tucannon Pack. A collar on a male wolf stopped transmitting over the winter, but reported sightings suggested the wolf was still alive.
At the end of 2016, the pack had a confirmed minimum number of four wolves.
In 2017, the pack had only two confirmed members and was not counted as a breeding pair.
For 2018, the pack had a minimum count of two wolves, and was not confirmed as a breeding pair. The 2019 annual survey detected three pack members, but pups were not confirmed for the year.
There were no successful breeding pairs counted in the 2020 annual survey, but a minimum of four pack members were counted.
In 2021 and 2022, eight wolves were confirmed in the pack.
The Tucannon pack broke apart after January 1st, 2023, and some stayed in the old pack territory while a portion of the pack shifted to the southeast and occupied a territory on the Oregon/Washington border, forming the Couse Pack (former WA139 Group). WA139F, a female wolf collared as a yearling in June 2022, was one of the pack members who dispersed to form the Couse Pack.
WA157M was collared in the Columbia pack territory as a 3-year-old in May 2023. He dispersed to the Tucannon pack territory during the summer, and the collar stopped transmitting location data. At the end of 2023, there were five wolves confirmed in the pack.
In 2024, there were four wolves confirmed in the pack, and they were not considered a successful breeding pair.
In January 2025, WDFW captured and collared a wolf in the pack.
