Washington's Wolf Population Grows Over 17%

The number of successful breeding pairs also increased by 27% in 2025, though human-caused mortality remains a concern.

Washington's wolf population increased by 17.4% in 2025, reaching 270 wolves in 49 packs, with 23 successful breeding pairs. However, at least 28 wolves died during the year, with 25 killed by humans, including 6 due to livestock conflicts and 12 from tribal hunting. Illegal killings also remain an issue, with research suggesting the discovered deaths are just a fraction of the actual poaching.

Why it matters

The growth in Washington's wolf population is encouraging, but the state's wolf recovery plan has not yet been fully achieved, with no breeding pairs established in the southern Cascades and north coast region. Reducing human-caused wolf mortality, including illegal poaching, will be crucial for allowing wolves to safely disperse and establish new packs across the state.

The details

According to the Washington Department of Fish and Wildlife, the state's wolf population increased from 230 wolves in 43 packs with 18 successful breeding pairs at the end of 2024, to 270 wolves in 49 packs with 23 successful breeding pairs by the end of 2025. However, at least 28 wolves died during the year, with 25 killed by humans. This includes 6 wolves killed for livestock conflicts, 4 by the department and 2 by livestock owners, as well as 12 wolves killed through tribal hunting by the Confederated Tribes of the Colville. There were also 3 known illegal killings under investigation.

  • At the end of 2025, Washington had 270 wolves in 49 packs, with 23 successful breeding pairs.
  • In comparison, at the end of 2024, the state had 230 wolves in 43 packs, with 18 successful breeding pairs.

What they’re saying

“It's encouraging that Washington's wolf population and number of breeding pairs increased last year, especially considering 2024's discouraging declines. Regaining lost footing is essential but these numbers don't mean wolves are recovered in Washington. The southern Cascades and North Coast boast some of the best wolf habitat in the state but still have no wolf packs or breeding pairs.”

— Amaroq Weiss, Senior wolf advocate, Center for Biological Diversity

“We have to figure out how to reduce human-caused mortality elsewhere in the state if we want to make it possible for wolves to safely make their way west and south into that third recovery zone. Once they get there, we must keep them safe from illegal poaching. The bottom line is that for Washington's wolf population to fully recovery, the department must focus on reducing human-caused wolf deaths.”

— Amaroq Weiss, Senior wolf advocate, Center for Biological Diversity

What’s next

The Washington Department of Fish and Wildlife will need to continue monitoring the state's wolf population and work to reduce human-caused mortality, including illegal poaching, in order to allow wolves to safely disperse and establish new packs in the southern Cascades and north coast region, the third recovery zone outlined in the state's wolf plan.

The takeaway

While the growth in Washington's wolf population is encouraging, significant challenges remain in ensuring the long-term recovery of the species across the state. Reducing human-caused wolf deaths, including from conflicts with livestock and illegal poaching, will be crucial for allowing wolves to fully reestablish themselves in suitable habitats throughout Washington.
