Sachuest Point National Wildlife Refuge

Project Sheet

Location: Newport County, Middletown, RI, US

Year: 2015 (ongoing)

Project Type(s): Habitat restoration

Project Description: The Maidford River Saltmarsh Restoration Project encompasses 11 acres of tidal salt marsh in the Sachuest Point National Wildlife Refuge, RI where elevation of the marsh prevented proper drainage at low tide. Eleven thousand cubic yards of sand were spread across the marsh using mechanical methods to target marsh elevation ranging between 2.2 and 2.3 NAVD88. This target elevation range is on the high end of the elevation range for Spartina patens. A thin layer of sand ranging from 2.5 to 30 cm was placed in the marsh to achieve these target elevations. The addition of sand to the marsh has improved marsh drainage, alleviated flooding of nearby roads, and improved habitat necessary for the growth of salt marsh plants critical for Saltmarsh Sparrow nesting. Plugs of marsh grasses were planted in May 2016 in locations were thin layer thickness was greater than 10 cm.
