This project permanently protected approximately 3,962 acres of estuarine wetlands and 160 acres of diked uplands in Port Susan Bay, Snohomish Co., WA. The estuary provides spawning and rearing habitat for multiple salmonids including the federal and state threatened chinook salmon and candidate coho salmon. A restoration technical feasibility assessment was completed. The goal was to design, engineer, and commit to appropriate future restoration actions consistent with watershed planning efforts and in cooperation with public lands and private partners. Loss of estuarine salt marsh and tidal channels has significantly reduced the quantity and quality of juvenile and adult salmonid habitat. The property is the largest block of private tidal and estuarine wetland habitat in the Puget Sound. It is actively threatened with residential, commercial and recreational development, and Spartina. With so little coastal wetland habitat remaining, the proposed acquisition is essential for preserving biodiversity, aiding in species recovery and enhancing natural ecosystem processes. The project addressed several recovery actions for the federally listed Chinook and other salmonids: 1) acquisition of sites with restoration potential 2) restoration of degraded estuarine habitat conditions preferred by juvenile chinook 3) potential restoration of sites where dike removal could enhance habitat forming processes and 4) studies that lead to development of priority future restoration projects.
