Beavers are typically associated with freshwater environments, but scientists have learned that they also survive and thrive in the shoreline marshes of the Salish Sea. New research is shedding light on the vital connection between tidal beavers and salmon.
Pink salmon now comprise nearly 80 percent of all adult salmon in the North Pacific. This record abundance is coming at a cost to other salmon species such as threatened Chinook, which compete with pinks for spawning territory. A new study shows that the ecological toll may extend all the way to endangered southern resident killer whales.
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
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.
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.
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.
An estimated 80% 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.
