NEW IN THE ENCYCLOPEDIA
The Puget Sound ecosystem is shaped by its physical environment. This article provides a summary of some of Puget Sound's geologic history as well as dynamic factors such as the flow of its rivers and currents.

A new study shows that increased populations of seals and sea lions are eating far more of Puget Sound’s threatened chinook than previously known, potentially hampering recovery efforts for both salmon and endangered killer whales.
Many groups have been formed around the goal of saving salmon, but few people talk about a concerted effort to save microscopic creatures. Whether or not a pro-bug movement catches on, future strategies to save salmon are likely to incorporate ideas for restoring streambound creatures known as benthic invertebrates.
Eelgrass, a marine plant crucial to the success of migrating juvenile salmon and spawning Pacific herring, is stable and flourishing in Puget Sound, despite a doubling of the region’s human population and significant shoreline development over the past several decades.

New EPA-funded Implementation Strategies are designed to target Puget Sound recovery in the most direct and coordinated way ever conducted by state and federal agencies. We report on how these strategies will affect Puget Sound’s Vital Signs for years to come, and why you should care (a lot).
A September 2016 report from the University of Washington Puget Sound Institute provides an overview of key products, results, and recommendations presented in three previous reports reviewing 50 projects from the first four years of the Puget Sound Marine and Nearshore Grant Program.
A 2016 article in the journal Conservation Letters makes policy recommendations to address shoreline armoring in the Salish Sea.
A "learn and adjust" strategy known as adaptive management plays a central role in state and federal Puget Sound recovery efforts. It is an approach that is gaining traction for ecosystem management worldwide. A December 2016 article from the Puget Sound Institute provides an overview of the concept and how it is being applied locally.
A September 2016 report from the University of Washington Puget Sound Institute summarizes and reviews 27 EPA-funded projects focusing on Puget Sound's marine and nearshore environments. The projects were conducted between 2011-2015 with support from the EPA's National Estuary Program. The report is an analysis of findings on shoreline restoration and derelict net and fishing gear removal.
The Puget Sound Actiona Agenda is a shared plan for Puget Sound recovery resulting from a collaboration by state and federal agencies, tribal governments, local governments, business and environmental groups, and others.
Drugs like Prozac and cocaine have been showing up in the region’s salmon. But these are just some of the potentially thousands of different man-made chemicals that escape into the Salish Sea every day, from pharmaceuticals to industrial compounds. Now the race is on to identify which ones pose the greatest dangers.
Efforts to reduce fire hazards over a half century ago have left an unintended trail of persistent environmental contaminants from flame retardant chemicals known as PBDEs. Bans and substitutes are still evolving.
New federal legislation, approved overwhelmingly by the U.S. Congress in December 2015 and signed into law by President Obama in June 2016, is designed to make sure that people and the environment are not harmed by new and old chemicals on the market.
The Puget Sound Recovery Atlas is a map-based, online tool that allows users to learn more about an important subset of Puget Sound restoration and protection activities.
A study in the journal PLOS ONE uses volunteer diver surveys to assess the impacts of sea star wasting disease in the Salish Sea. Data shows that sunflower sea stars were especially hard hit and have all but disappeared from the region.
New numbers show progress in the state’s efforts to remove shoreline armoring, but they don’t tell the whole story.
Scientists are testing ways to use transplanted shellfish such as mussels to monitor toxic contaminants in Puget Sound.
Invasive species are considered a top threat to the balance of ecosystems worldwide. New discoveries of non-native green crabs in Puget Sound have highlighted that concern here at home, but invasive species can impact more than just the food web. Some introduced species can produce toxins that accumulate in shellfish or by directly infecting the human body.
The Puget Sound Ecosystem Monitoring Program released its fifth annual Marine Waters Overview this week. The report provides an assessment of marine conditions for the year 2015 and includes updates on water quality as well as status reports for select plankton, seabirds, fish and marine mammals.
Another European green crab has been spotted in Puget Sound prompting concern that the species may gain a foothold in the region.
Sand lance in parts of British Columbia are ingesting small pieces of plastic that may be passed through the food web.
After an almost complete collapse in the 1970s, harbor porpoise populations in Puget Sound have rebounded. Scientists are celebrating the recovery of the species sometimes known as the "puffing pig."
Social scientists around the Salish Sea are predicting the effects of environmental change through the lens of culturally important foods.
A 2016 paper in the journal Society and Natural Resources looks at the creation of human well-being indicators across three regions in the Puget Sound watershed. The author suggests that overarching domains for these indictors might be applied more broadly in other environmental contexts.
Some of the most important fish in the Salish Sea food web are also the most mysterious. Researchers have only begun to understand how many there are, where they go, and how we can preserve their populations for the future. A University of Washington researcher describes how scientists are looking into the problem.
Gaps in regulations could allow invasive species to hitch a ride on ships and boats. We report on some of the potential impacts, and how state and federal agencies are trying to solve the problem.
Concerns over the potential arrival of the European green crab have inspired a small army of volunteers. A search is underway for early signs of an invasion.
Almost twenty years ago, volunteer biologists began an intensive survey for invasive species in the marine waters of Puget Sound. In a little over a week of hunting, they found 39 such species, including 11 never before seen in the region.
The Washington Invasive Species Council evaluated more than 700 invasive species in and around Washington, considering their threats to the state’s environment, economy, and human health. They included terrestrial plants and animals, aquatic plants and animals (both freshwater and saltwater), insects and diseases. In the end, the council listed 50 “priority species” for action, including five marine animals and two marine plants, along with one virus that infects fish.
A July 2016 report from the University of Washington Puget Sound Institute summarizes and reviews 10 EPA-funded projects focusing on Puget Sound's marine and nearshore environments. The projects were conducted between 2011-2015 with support from the EPA's National Estuary Program. The report is an analysis of findings on invasive species, toxics, oil spill, and integrated risk assessment.
Formerly known as “Red Tide”, harmful algal blooms are a health concern for both wildlife and humans. The following is a brief review of some of these algae and their effects.
