The role of estuaries in the ecology of juvenile Pacific salmon and trout in Puget Sound

This overview describes the different ways that juvenile Pacific salmon and trout use estuaries, and why those differences are important for ecosystem recovery efforts. The report was commissioned by the University of Washington Puget Sound Institute with funding from the Environmental Protection Agency's National Estuary Program.

A new beginning for threatened Chinook

The Stillaguamish River is home to what may be the most imperiled 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. E

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.

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

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?
