Restoration Projects for Urban Shorelines and Riparian Habitats in Washington State

This report outlines several restoration initiatives aimed at improving urban shorelines and riparian habitats across Washington State. Projects include Saltwater Park, Washington Park Arboretum, Coal Creek, Gamble Creek, Swamp Creek, TCC Natural Area, and Yesler Creek. Each project targets invasive species, such as Scots broom and Himalayan blackberry, with goals to stabilize slopes, enhance native plant growth, and support salmon populations. Emphasizing the use of native flora, these restoration efforts aim to revitalize ecological balance in urbanized environments.
