Abstract:

Raising elevation with sediment addition is a potential strategy to enhance tidal marsh resilience in the face of rising seas. A diverse team of state and national coastal managers and scientists reached consensus on recommendations for the use of thin-layer placement (TLP) of sediments in tidal marshes.

In this webinar, "Building Marsh Capital: Adding Sediment to Help Marshes Face Rising Seas," presenters shared thin-layer placement recommendations, permitting guidance, and monitoring. The presenters also reported on findings from greenhouse experiments led by Drexel University that examined how different marsh plant species respond to varying sediment conditions. Finally, they described a coordinated restoration experiment conducted across eight National Estuarine Research Reserves on US East and West Coasts.

This webinar was originally presented on February 20, 2020 as part of the Restoration Webinar Series, hosted by the National Oceanic and Atmospheric Administration and U.S. Fish & Wildlife Service's National Conservation Training Center.
