Found at the interfaces of land formations and water, smooth cordgrass (Spartina alterniflora) is an herbaceous, native grass that densely inhabits shorelines. Compact, vegetative smooth cordgrass colonies grow along shorelines and inter-tidal flats of coastal wetlands such as canal banks, levees, marshes, barrier islands, and other regions of soil-water interface. This grass is highly adaptable to a variation of water depths and salinity levels making it a resilient species heavily used for coastal restoration. With an extensive rhizome system, smooth cordgrass is also highly effective as a soil stabilizer for loose soils, contributing to anchorage of the plants and sediment, as well as decrease of erosion effects. Smooth cordgrass acts as a natural buffer which dissipates energy of storm surge and wind impact to interior lands.
The Coastal Wetlands Planning, Protection, and Restoration Act frequently uses smooth cordgrass plugs during vegetative plantings due to the plant’s insensitivity to water and salinity levels, and its success in significant erosion protection to shorelines.
