The Hood Canal Summer Chum Riparian Enhancement and Knotweed Control Project is a restoration project focused on eight Hood Canal Summer Chum river basins, with the goal of restoring the structure and function of native riparian plant communities. The riparian zone is defined as the transitional area between terrestrial and aquatic ecosystems, including the active floodplain, riverine wetlands, terraces and adjacent upland that directly contribute organic matter to the active channel or floodplain. According to WDFW's Riparian Ecosystems, Volume 2: Management Recommendations (2020), riparian buffer widths for Type 1 or the equivalent Type S streams "shoreline of the state", should be a minimum of 215-225 feet from the active channel based on one 200-year site-potential tree height (SPTH). This project will restore degraded riparian habitat, through replanting with an emphasis on conifers and fast growing shade producing deciduous trees and shrubs; and the survey and treatment of the invasive knotweed complex (polygonum spp.).
