Themes from the 2022 Salish Sea Ecosystem Conference

Stories exploring major research themes presented during the virtual 2022 Salish Sea Ecosystem Conference.


A new report says further study may reveal why experts cannot find expected benefits to salmon populations, despite widespread use of wood in stream restorations.

Occasionally, our magazine includes reports and essays from guest writers on the subject of Puget Sound ecosystem recovery. Biologist and author Eric Wagner has this look at an ongoing harbor seal survey at the mouth of the Stillaguamish River. Wagner says the study hinges on a basic question: Who is eating the salmon? 

The Swinomish Indian Tribal Community has begun constructing the first known clam garden to be built in modern times. They hope that what was once an ancient way of cultivating shellfish can now be a hedge against climate change.

Puget Sound Restoration Fund has launched a network to track declining kelp populations in the Salish Sea. The three-year initiative aims to support and standardize underwater monitoring to improve kelp conservation in the region.

Dam removals are often associated with salmon recovery, but new research on the Elwha River suggests that birds also benefit. Scientists say birds are a sometimes-overlooked indicator of river health.

It has been four summers since a mother orca’s dramatic vigil brought worldwide attention to the plight of Puget Sound’s southern resident killer whales. A recent gathering of legal experts, conservationists, and academic scholars looked at how perceptions of the whales have changed since then and whether laws and policies should reflect new thinking about ethical responsibilities to orcas and other animals. 

Endangered sea stars could help control urchin populations, aiding kelp forests in the Salish Sea, according to a new study at the University of Washington’s Friday Harbor Laboratories. Scientists say captive baby sea stars eat even more urchins than their adult counterparts.

Research on the sounds and feeding behavior of Puget Sound's southern resident orcas is providing new insight into how the whales respond to underwater noise. A recent online conference brought together some of these findings along with discussions on how to reduce the impacts of noise from vessel traffic.

A state law going into effect this month will significantly increase funding for the cleanup of abandoned and derelict vessels in Puget Sound. The funding will add about $4.3 million annually to remove hazardous sunken wrecks and related pollutants.

New research suggests that recovery efforts are working for Puget Sound’s threatened yelloweye rockfish. Preliminary models show "considerable improvement" in population numbers.

A pilot project to create a 'living dike' in Canada's Boundary Bay is designed to help a saltwater marsh survive rising waters due to climate change.
