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 […]

Identifying chemical suspects in stormwater
Scientists know this much about stormwater: It can be extremely toxic. It can kill exposed fish such as coho salmon within hours. But figuring out exactly what is in stormwater has been a complex puzzle that has so far confounded scientists. Many of the chemical compounds in it remain unidentified. Is there such a thing as typical […]

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 […]

New report shows high impact of toxic pollution on the Salish Sea
A new report about toxics in the Salish Sea brings together findings from over 40 research programs and includes case studies of Chinook salmon, shellfish and killer whales, among other species: The report from the Puget Sound Ecosystem Monitoring Program and co-edited by PSI’s Andy James highlights trends for toxics during 2016. While some of […]

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 […]

PSI study links happiness to interactions with nature
Can nature make you happy? Science weighs in. A recent study by PSI social scientist Kelly Biedenweg found that Puget Sound residents reported being happier when they engaged with the natural environment. “We (in the Pacific Northwest) are pretty much the leaders in trying to understand how happiness and integration with the environment relate to each other,” Biedenweg […]

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 […]

‘Bold actions’ to be discussed in a revised Chinook Implementation Strategy
By Christopher Dunagan, Puget Sound Institute A desire to come up with “bold actions” for rebuilding Chinook salmon runs in Puget Sound has slowed approval of the first Chinook Implementation Strategy designed to accelerate recovery efforts for the threatened species. The Puget Sound Salmon Recovery Council, which oversees salmon-related planning, was scheduled to adopt the […]

Special report for Puget Sound policymakers
It used to seem easier to spot the polluters. There were the usual suspects: Industrial pipes pumped toxic chemicals into the water; dams blocked the way for salmon; natural resources were over-harvested. Those problems still persist, but ecosystem management in Puget Sound has become increasingly complicated since the 1970s and 1980s. Scientists now recognize that […]
