Round Island Marsh Restoration

Author(s): Tracy, S.

The Utilization of Dredge Material for Marsh Restoration in Coastal Mississippi Project was funded by the National Fish and Wildlife Foundation (NFWF) in November 2014. Over many decades, priority bays on the Mississippi Gulf Coast have experienced significant impacts due to shoreline erosion, storm damage, and alterations to sediment transport, contributing to the loss of thousands of acres of tidal marsh habitat. In the past, most dredge material has been disposed of offshore or in upland dredge disposal areas. This project advances Mississippi’s beneficial use program to facilitate a cost-effective, sustainable approach to restoring and protecting significant coastal marsh and bay shorelines. An example of one of these restoration efforts is located in Pascagoula, MS at the Round Island Coastal Preserve. Over 200 acres of marsh were created using dredge material provided by the U.S. Army Corps of Engineers from the Pascagoula Channel. This marsh will create habitat for living coastal and marine resources, reduce erosion along bay shorelines, and improve water quality.
