Description    


King County will restore 12.9 acres of riparian habitat along 1.02 miles of Green River shoreline nearly devoid of tree cover, by removing invasive plant species and planting native trees and shrubs. The project sites are in public ownership and were identified by the Muckleshoot Indian Tribe as an area with high or critical need for tree shade. Restoring native riparian vegetation will benefit spawning and rearing ESA listed Chinook salmon and steelhead in the Lower and Middle Green River basins. Historic removal of tall, native trees from the banks of the river allows too much sunlight to reach the water, resulting in summertime water temperatures that frequently exceed state water quality standards and the lethal threshold for ESA listed Chinook salmon and steelhead, as well as chum, coho, and pink salmon. The Green River Temperature TMDL identified the lack of shade as a main driver for these high temperatures and the need for tall, continuous riparian vegetation along the river’s banks (Department of Ecology, 2011). To support this finding, the Muckleshoot Indian Tribe developed a series of maps prioritizing shorelines where trees would most effectively shade the river based on solar aspect. These studies informed WRIA 9’s 2016 Re-Green the Green Vegetation Strategy, which set goals and named priority reaches for revegetating the Green-Duwamish River shoreline.

Project Benefit    


The goal of this project is to restore native riparian vegetation to benefit spawning and rearing ESA listed Chinook salmon and steelhead in the Lower and Middle Green River basins.
