A western pond turtle perched on log next water.

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.


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.

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.

Summer chum salmon in Hood Canal are making a remarkable comeback. Could it be enough to support their removal from the Endangered Species List?


Underwater view of large shark with its mouth opened wide to filter feed.

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?


View of a single black and white Dall's porpoise swimming near the surface of the water.

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.

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.


Report cover

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.

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. 


Two seabirds with black and white plumage floating on water.

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.

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.

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.

Research that began in Puget Sound has revealed much about the cellular-level assault on vulnerable salmon and trout, yet the puzzle remains incomplete.

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 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.

Each year, the Puget Sound Ecosystem Monitoring Program releases the annual Puget Sound Marine Waters Overview report. The latest report combines a wealth of data from comprehensive monitoring programs and provides a concise summary of what was happening in Puget Sound’s marine waters during 2022. The report represents the collective effort of 84 contributors from federal, tribal, state, and local agencies, academia, nonprofits, and private and volunteer groups.


A stream full of hundreds of swimming salmon.

An estimated 70% of all the salmon in the North Pacific are pink salmon. Scientists say the extreme abundance of pinks could be causing a "trophic cascade" that is harming species across the food web.


Report cover

The 2023 State of the Sound is the Puget Sound Partnership’s eighth biennial report to the Legislature on progress toward the recovery of Puget Sound. The document reports on both the status of the Partnership's recovery efforts and a suite of ecosystem indicators referred to as the Puget Sound Vital Signs.

All across the region, communities are finding that rising seas and rising rivers are two sides of the same coin. New research funded by the Environmental Protection Agency may help managers target their responses to climate-fueled flood risks in Puget Sound. The following article was commissioned by the Habitat Strategic Initiative Lead (HSIL), a cross-agency team co-led by the Washington Departments of Fish and Wildlife and Natural Resources.

Zooplankton are critical to the marine food web, but until recently there have been few surveys of the zooplankton community in Puget Sound. Ongoing monitoring is now revealing a system full of complexity and surprises. The following article was commissioned by the Habitat Strategic Initiative Lead (HSIL), a cross-agency team co-led by the Washington Departments of Fish and Wildlife and Natural Resources.

Beavers provide critical benefits for wetland ecosystems but can also alter the landscape in ways that are unpredictable for property owners and conservationists alike. New techniques are helping humans and beavers share the landscape with the goal of benefiting both parties. The following article was commissioned by the Habitat Strategic Initiative Lead (HSIL), a cross-agency team co-led by the Washington Departments of Fish and Wildlife and Natural Resources.


En toda la región, las comunidades están descubriendo que el aumento del nivel del mar y los ríos son dos caras de la misma moneda. Una nueva investigación financiada por la Agencia de Protección Ambiental puede ayudar a los administradores a enfocar sus respuestas a los riesgos de inundaciones provocadas por el clima en el estrecho de Puget.
