Biologist and science writer Eric Wagner recently returned from a trip to observe pigeon guillemots on Protection Island. He wonders: How much do we really know about the health of seemingly abundant bird populations?
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.
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.
Prehistoric-looking lamprey are recolonizing parts of the Elwha River that they have not occupied for more than 100 years. Like salmon, the culturally and ecologically important fish also move from saltwater into rivers to spawn. And like salmon, lamprey were devastated by the dams that once blocked their way. We conclude our series 'Returning home: The Elwha's genetic legacy.'
Bull trout appear to be thriving in nearly every section of the Elwha River. Populations there have at least doubled in the years since dam removal, signaling good news for a species that has struggled throughout the West. We bring you part six of our series 'Returning home: The Elwha's genetic legacy.'
Restoration managers are hopeful that populations of coho, chum and pink salmon will rebound on the Elwha River as the fish take advantage of newly accessible habitat. Part five of our series 'Returning home' examines the importance of genetically distinct salmon runs.
The return of sockeye to the Elwha River is intriguing scientists. Could nearby freshwater kokanee help re-establish resident populations? We continue with part four of our series 'Returning home: The Elwha's genetic legacy.'
