Cedar River Watershed Biodiversity
Lichens and mosses on felsenmeer
The Cedar River Watershed is a cross-section of habitat from the central Cascade Mountains crest to the Puget Sound lowlands. It provides protection to a rich biological diversity.
The watershed contains old-growth and second-growth forest, a variety of non-forested terrestrial habitats, and numerous streams and lakes.

The watershed provides a rare opportunity to preserve and restore biodiversity in western Washington. The City of Seattle is actively assessing and documenting its current biodiversity to serve as a regional benchmark and to help implement its habitat restoration activities under the Habitat Conservation Plan.

Note: The Cedar River Watershed referred to in these web pages consists of the upper two-thirds of the hydrologic watershed, which is almost entirely under City of Seattle ownership. The lower third of the watershed, downstream of Landsburg, is largely under private ownership in unincorporated King County.
