A new beginning for endangered Chinook
The Stillaguamish River is home to what may be the most endangered stock of Chinook salmon in all of Puget Sound. What scientists are learning here at the Stillaguamish estuary on Port Susan Bay could help turn the tide for these fish and other salmon around the region.
Fin whales in the Salish Sea
Fin whales are the second-largest species of animal on the planet. Their occasional presence in the Salish Sea is notable because they are rare and listed as Endangered federally and in Washington State. Sightings today are considered most likely to occur in the Strait of Juan de Fuca, which is closest to their migration route on the outer coast. Fin whales inhabit deep, oceanic waters, however, at least 14 sightings of four different fin whales have been documented in inland waters in the past decade. This suggests a possible increase in their use of local waters.
All killer whales will remain one species — for now, according to marine mammal committee
A formal proposal to designate resident and Bigg’s killer whales as separate species has been rejected by a committee widely recognized as the authority in naming new marine mammal species.
Decision time approaches for two new orca species, as other issues bring new questions
Scientists are making the case that the world's orcas should be divided into two new species. Voting for the proposed change was scheduled to take place last week at the Society for Marine Mammalogy. [Update: Read about the decision here.]
A head start for Puget Sound's endangered turtles
The Puget Sound region is known for its salmon-filled estuaries and coastal forests, but on the southern portion of its range, evergreens give way to small patches of rolling grasslands that are home to some of Washington's rarest species. One of those species, the northwestern pond turtle, was recently proposed for listing under the Endangered Species Act. A captive breeding program is preparing these turtles for the challenges of life in the wild.
The voice of eelgrass
Wade out into the shallows of Puget Sound on a warm, sunny day and put your ear close to the water. You might catch the faint, champagne-like bubbling of eelgrass.
Rare tidal marshes set the table for salmon recovery
Tidal wetlands are crucial to Chinook salmon recovery but are among the most threatened habitats in Puget Sound. In 2012, The Nature Conservancy began restoring a 150-acre section of tidal marsh on Port Susan Bay at the mouth of the Stillaguamish River. That project is entering a new phase and may soon connect with other adjacent restoration efforts put forth by the Stillaguamish Tribe.
Hood Canal summer chum could be first-ever salmon removed from Endangered Species List
Summer chum salmon in Hood Canal are making a remarkable comeback. Could it be enough to support their removal from the Endangered Species List?
Will these gentle giants return to the Salish Sea?
A shark species the length of a bus was once common in the Salish Sea. Then it was labeled a "destructive pest" and nearly wiped out. Can the gentle and often misunderstood basking shark make a comeback?
The decline of Dall’s porpoise in the Salish Sea
Dall’s porpoises have declined in the Salish Sea since the early 1990s for reasons that are unknown. However, the species, which remains abundant in inshore waters of Alaska and in open coastal and offshore waters of the North Pacific Ocean, is not considered threatened or endangered. Major threats to Dall’s porpoise populations include direct hunting, by-catch in fisheries, and the impacts of environmental contaminants.
Under a new proposal, our local orcas — resident and Bigg’s killer whales — would each become a new species
A scientific paper, published on March 27th, spells out the unique physical and genetic characteristics that should make each group a separate species, with the proposed scientific names Orcinus ater for residents and Orcinus rectipinnus for Bigg’s.
Habitat protection and restoration in Puget Sound: An overview of Strategic Initiative Lead investments 2016-2023
Between 2016 and 2021, $21 million provided by the Environmental Protection Agency (EPA) funded 100 different projects to protect, restore, and study critical habitats in Puget Sound. This publication presents an overview of many of the key accomplishments and lessons learned from these efforts. It is a catalog of some of the ‘big ideas’ presented by the scientists and conservationists involved, and it is meant to inform and guide future Puget Sound recovery efforts. This overview is based on the full synthesis report, “Synthesis of Habitat Strategic Initiative Lead 1.0 2016-2023 Investments for Puget Sound Recovery," published by the Puget Sound Institute.
The words ‘in common with’ were pivotal to Judge Boldt’s ruling on Native American fishing rights
Three common words and their legal interpretation a half-century ago helped set the stage for a cultural revival among Native Americans while propelling an environmental movement that still resonates today. Environmental reporter Christopher Dunagan revisits the legal reasoning behind the famous Boldt decision that upheld tribal fishing rights in the state of Washington.
Science notebook: Winter studies of Puget Sound's threatened marbled murrelets
For years now, scientists have been braving the cold winter waters of Puget Sound to study one of the region's most enigmatic seabirds, the marbled murrelet. Listed as threatened under the Endangered Species Act in Washington, Oregon, and California, marbled murrelets nest in old-growth forests but find their food at sea. Much research on the birds has centered around the spring and summer breeding season, but less is known about what the murrelets do in winter. That puzzle prompted a team of scientists from the Washington Department of Fish and Wildlife to head out on the water last January. Writer and biologist Eric Wagner joined the expedition and brought back these notes from the field.
Puget Sound perceptions of environmental and climate change
About 80% of respondents to a 2022 human wellbeing survey reported some level of concern for environmental impacts affecting Puget Sound. The survey was funded by the Puget Sound Partnership and led by members in Oregon State University’s Human Dimensions Lab.

Lawsuits fly, as regulators come to grips with a toxic tire chemical
Finding a replacement for 6PPD in tires is one major challenge; another is to prevent the highly toxic derivative 6PPD-Q from reaching salmon streams and killing fish.
Scientists worldwide are immersed in studies of a deadly tire chemical
Research that began in Puget Sound has revealed much about the cellular-level assault on vulnerable salmon and trout, yet the puzzle remains incomplete.
Photographing the 'Creek of Hope'
Longfellow Creek near West Seattle's industrial district still draws spawning salmon despite a century of city development and an onslaught of toxic chemicals. A current exhibit by photographer Tom Reese explores this often-overlooked gem of urban nature.
Northern elephant seals in Puget Sound and vicinity
Northern elephant seals were hunted heavily in the 19th century and believed to be extinct by 1892. However, a small remnant population (~50–100 animals) off the western coast of Mexico grew to populations in the United States and Mexico to at least 220,000 individuals as of 2010. Elephant seals are distributed in the central and eastern North Pacific Ocean, from as far north as Alaska down to southern Baja California. Sightings of elephant seals were once considered rare in the Salish Sea, but increasingly single individuals are known to haul out onto sandy beaches on Smith, Protection, and Whidbey Islands. In 2010, a local breeding population established itself along the lower west side of Whidbey Island in Puget Sound.
