Marsh restoration technology has been applied at a variety of locations to vegetate intertidal dredged material disposal sites, stabilize shorelines, mitigate damage to natural marshes and to revegetate one marsh destroyed by an oil spill. Goal 2: Reduce tidal scour in Elkhorn Slough. Julie. Impacts to tidal marshes caused by tidal restrictions vary by type of restriction and its severity, as well as the geomorphology of the system. American beach grass was planted along the restored dune, and it is thriving. The Elkhorn Slough Tidal Marsh Restoration Project will add sediment to these former marshes, returning the land to the elevation necessary for marsh plants to thrive. Further research is needed to determine the success … This service is more advanced with JavaScript available, Part of the The Elkhorn Slough National Estuarine Research Reserve and the Elkhorn Slough Foundation work with government, community agencies and other partners to protect this precious and scarce environment. Labeled the Tidal Marsh Restoration Project, the restoration will ensure Hester Marsh outlasts the drowning of most other Elkhorn salt marshes, projected to occur within 50 years. We plan to add sediment to some of these former marshes, returning the land to the elevation necessary for marsh plants to thrive. It is anticipated that at least 10 permits will be needed from various regional, state and federal entities. As the largest tidal marsh restoration in Oregon to date, an extensive amount of work was coordinated with FWS and designed, engineered, constructed, and contracted by DU. The South Bay Salt Pond Restoration Project is the largest tidal wetland restoration project on the West Coast. They are dominated by pickleweed, and in many parts of the Slough the marshes are thousands of years old. The interconnectivity of wetlands 10. 01 / 05. © 2020 Springer Nature Switzerland AG. Research shows that tidal marsh restoration can be evaluated through various factors, such as vegetation, biogeochemical responses (e.g. The project consisted of (1) excavation and debris removal to enlarge an existing north embankment breachon Calhoun Cut at a northern arm of … 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 significance of pickleweed-dominated tidal salt marsh in Elkhorn Slough, California.
