Monitoring

Scientists can now identify the presence of species just by testing the water for traces of DNA. The relatively new technique is being compared to the invention of the telescope or the microscope as a significant new tool for understanding ecosystems like Puget Sound. It could be a revolution for tracking the movements of all kinds of species, from salmon and killer whales to invasive green crabs.

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.

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.

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.

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.

A new strain of avian flu has been sweeping the globe since 2020, leaving thousands of dead seabirds in its wake. This past summer, it arrived at a colony of Caspian terns at Rat Island in the Salish Sea, with catastrophic results.
