Smooth cordgrass is the dominant emergent grass species found growing along tidal salt marshes of the Atlantic and Gulf coasts. It is utilized extensively for erosion control along shorelines, canal banks, levees, and other areas of soil water interface. Smooth cordgrass is an effective soil stabilizer used on interior tidal mudflats, dredge-fill sites, and other
areas of loose and unconsolidated soils associated with marsh restoration. Under natural conditions on tidal marshes, vigorous stands of this grass will absorb wave energy and screen suspended solids from intertidal waters, while uptaking available nutrients in the sediments.
