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.
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.
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?
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.
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.
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.
Puzzling encounters between endangered killer whales and harbor porpoises point to questions about prey availability and whale culture, scientists say. Are the whales playing, practicing their hunting skills, or is something else going on?
