The Puget Sound Institute

The Puget Sound Institute is a cooperative agreement between the University of Washington, the U.S. Environmental Protection Agency, and the Puget Sound Partnership, seeking to catalyze rigorous, transparent analysis, synthesis, discussion and dissemination of science in support of the restoration and protection of the Puget Sound ecosystem.

Traditional Ecological Knowledge

Traditional Ecological Knowledge (TEK), sometimes called Indigenous Knowledge, refers to cumulative knowledge and experience that indigenous cultures have of their environment. In the last thirty years, there has been growing interest in TEK as a resource for restoration and conservation projects.

In the south a persistent marine layer over the lowlands keep conditions cooler. River flows are high. Water temperatures approach 15 °C. High fluorescence in the Main Basin Extensive red-brown blooms in South Sound. In Whidbey Basin, higher DO and algal bloom in surface waters.

Featured resource: Puget Sound Stream Benthos

Puget Sound Stream Benthos is a data management project which monitors benthic invertebrates in streams and rivers in the Puget Sound region. The system is maintained and operated by King County and was the result of a joint effort between King, Pierce, and Snohomish Counties.

King County wetland habitat

Wetlands are recognized as critical ecosystems for biodiversity because of their disproportional use by wildlife and exceptional habitats for plants. It is their unique combination of shallow aquatic habitats and adjacent terrestrial conditions extending over a wide range of geomorphic and elevational settings that accounts for their ecological complexity and resultant richness. Because of their

King County subalpine and alpine habitat

Except for a very small area in the SE corner of the County, the subalpine and alpine habitats are located in the North Cascades Ecoregion that occupies the NE quarter of King County. This ecoregion is composed of steeply dissected valleys that rise precipitously to the subalpine (montane) forests, meadows, and parklands and, in a short distance more, to the alpine ridges and peaks of the Cascade

King County rivers and streams

The diversity of streams in the county is a reflection of the diversity of its geography. From the small rivulets that begin high in the Cascade Mountains, to the brooks that flow gently across the lowlands, to the five major rivers of the county, there are over 4,800 kilometers (3,000 miles) of perennial streamcourses in King County.

Despite the impressive total length, King County has no rivers

King County riparian habitat

Riparian habitats are often characterized by particular trees and shrub species that line the banks of most rivers and streams in the lowlands and foothills of King County.
