Climate change

Raging wildfires can be an ecological disaster, especially as the planet warms due to climate change. But in small doses, some wildfires are actually beneficial. In prairie habitats, fires can enrich soils and maintain native plant species. In late September, state wildlife biologists oversaw several controlled burns near Joint Base Lewis-McChord (JBLM) as part of an effort to preserve habitat for the endangered Taylor's checkerspot butterfly. Less than 3% of Puget Sound's prairies now remain and are mostly concentrated along the region's southern edges, including land on the military base. Listen to a recording of some of the action, including comments from JBLM fire manager and biologist John Richardson.

Social Science for the Salish Sea (S4) provides a foundation for future research projects, accessible information for planning or management decisions, and synthesized content to inform ecosystem recovery.

Warming waters threaten the recovery of salmon in Puget Sound. New findings about stream temperature could help salmon survive the threats of climate change.

The number of golden-crowned kinglets in the Puget Sound watershed has declined by more than 91% over a recent 50-year period, according to data from the North American Breeding Bird Survey. The data was reported by the Washington Department of Fish and Wildlife, which tracks the information for the Puget Sound Partnership’s terrestrial bird indicator. The indicator was established to monitor the health of Puget Sound’s species and food webs.

The Salish Sea Model is a computer model used to predict spatial and temporal patterns related to water circulation in the Salish Sea. It was developed at the United States Department of Energy's Pacific Northwest National Laboratory with funding from the Environmental Protection Agency. It is housed at the University of Washington Center for Urban Waters which is affiliated with the Encyclopedia of Puget Sound.  

Close to 30% of Puget Sound's shoreline is armored with seawalls and other structures meant to protect beaches against rising tides and erosion. But science increasingly shows that these structures are ineffective and cause significant harm to salmon and other creatures. State and federal agencies have been encouraging private property owners to remove armoring in a race to improve habitat, but why did so much of it start appearing in the first place?
