Shoreline modification is pervasive in the Puget Sound region and the use of physical structures to curtail erosion, known as armoring, degrades ecosystems and reduces salmonid forage opportunities. Shore Friendly, a program of the Washington Department of Fish and Wildlife, supports waterfront stewardship on private lands through technical

A chemical found in tires is leading to the deaths of untold numbers of coho salmon in Puget Sound every year. Chemical companies are searching for an alternative but say the unique chemistry and function of 6PPD are major challenges. This article is part one of a three-part series.

Formal legal processes are underway in Washington and California to seek alternatives to the highly toxic chemical in tires. We continue with part two of our three-part series on efforts to find a replacement for 6PPD.

With a worldwide market valuation somewhere around $1 billion a year for the single chemical 6PPD, tire companies and their chemical suppliers are working overtime to find a safe and effective replacement for the tire additive. The financial stakes are enormous, since virtually every tire on the market today contains 6PPD.

A 2026 report assesses region-wide cumulative risks for eelgrass and kelp in Puget Sound, identifying hotspots of concern, the relative threats, and projected future risks across eight marine subregions.

Researchers at the Puget Sound Institute and Washington Department of Fish and Wildlife present the first comprehensive risk assessment of threats to eelgrass and canopy kelp in Puget Sound.
