tidal marsh restoration

Introduction. A new trail and viewing platform between Bayfront Expressway and the southern edge of Bedwell Bayfront Park Specifically, wetlands play a crucial role in the productivity of coastal waters, biogeochemical cycling, and geomorphological stability. California’s salt marshes have become a rare habitat in recent history and the various laws in place protecting them are evidence of their value. Tidal marshes are increasingly vulnerable to degradation or loss from eutrophication, land-use changes, and accelerating sea-level rise, making restoration necessary to recover ecosystem services. The refuge’s large tidal marsh restoration project is entering its final stages this spring. The significance of pickleweed-dominated tidal salt marsh in Elkhorn Slough, California. The regional responses of winter shorebird populations in the nearly 3,000 ha estuary of Tomales Bay, California, to the restoration of 223 ha of historic tidal wetlands were evaluated for 27 years: 19 years prior to tidal reintroduction and 8 years after tidal reintroduction. Lower Yolo Tidal Marsh Restoration Project . Goal 2: Reduce tidal scour in Elkhorn Slough. Permit applications are in preparation. Tidal salt marshes undergo the processes of subsidence and sediment accretion, which often allow them to maintain a stable elevation in pace with the natural rate of sea level rise.
