It has been more than ten years since the first of the Elwha River’s two dams was breached, and scientists are gaining new perspectives on the resilience of that ecosystem and its species. The dramatic sight of a river suddenly running free, and the swift return of its salmon has captured the public’s imagination. But a key […]

With sea-level rise, waterfront owners confront their options
Climate change could cause sea levels to rise more than four feet in some parts of Puget Sound, leaving shoreline residents with some tough decisions. Experts say fighting the waves with conventional seawalls may not be the answer. Read the story in our online magazine Salish Sea Currents.

Are we making progress on salmon recovery?
In recent decades, hundreds of millions of dollars have been spent to restore habitat for Puget Sound salmon. This month, PSI senior writer Christopher Dunagan looks at how scientists are gauging their progress. Are environmental conditions improving or getting worse? The answer may depend on where you look and who you ask. Read the article […]

Update: Killer whale miscarriages linked to low food supply
Our 2016 article “Killer whale miscarriages linked to low food supply” provided an early look at a study published this week in the journal PLOS ONE. PSI senior writer Christopher Dunagan wrote the article based on research that was presented at the 2016 Salish Sea Ecosystem Conference, and it remains a helpful summary of the […]

Eelgrass declines pose a mystery
New in Salish Sea Currents: Scientists want to know why eelgrass is on the decline in some areas of Puget Sound and not others. The answer will affect future strategies for protecting one of the ecosystem’s most critical saltwater plants. Read the full story from contributing writer Rachel Berkowitz in the Encyclopedia of Puget Sound.

Saving the last estuaries
When rivers spill into Puget Sound, they provide some of the most productive habitat in the ecosystem. The ebb and flow of the tides creates a perfect mix of fresh and salt water critical for young salmon. But over the past 100 years, the region’s tidal wetlands have declined by more than 75%. A coalition of […]

Urban lifestyles help to protect the Puget Sound ecosystem
The state of Washington estimates that the Puget Sound area will grow by more than 1.5 million residents within the next two decades. That is expected to have profound effects on the environment as more and more people move to undeveloped areas. The race is on to protect this critical rural habitat, but planners say […]

Program envisions fewer floods and more salmon
This week in Salish Sea Currents: PSI senior writer Christopher Dunagan reports on a new approach to flood control in Puget Sound. Rivers, scientists say, can be contained by setting them free. Conservationists hope this is good news for salmon recovery. The story is part of our ongoing series on the science of Puget Sound recovery. Funding […]

Finding a strategy to accelerate Chinook recovery
New in Salish Sea Currents: We continue our series on Puget Sound’s EPA-funded Implementation Strategies. This week we take on Chinook recovery. As threatened Chinook populations continue to lose ground, the state is looking to new strategies to reverse the trend. In the Skagit watershed, the scientists — and the fish — are among those […]
