Dredging and Seeds Help Restore Marsh Ecology

As sea levels rise, Ninigret Pond’s salt marshes are drowning, converting to mud flats or open water. The sand swept in by shoreline currents is covering eelgrass beds, leaving communities without a natural buffer against storms and hindering navigation for area boaters.

To rectify these issues, sediment is being dredged from a nearby channel and used to elevate areas adjacent to the salt marsh. The newly elevated area should be covered with vegetation within a few years, thanks to the marsh grass seed being planted as part of this project. This restoration will go a long way toward preserving the marsh ecology and lessening sediment build up in the pond. The deeper channel will improve navigation.

The Rhode Island Coastal Resources Management Council is coordinating this effort with various partners, including the Narragansett Bay National Estuarine Research Reserve. The information learned through this project will be used to better inform coastal wetland monitoring and restoration strategies.

The U.S. Department of the Interior provided funding for the project. The Rhode Island Coastal Resources Management Council is part of the National Coastal Zone Management Program. (2017)
