Planting of Levees at Corps of Engineers Dredge Material Placement Area for Erosion Protection, Brazoria County, Texas

Wetland plants provide natural erosion protection. Smooth cordgrass (Spartina alterniflora) is frequently used for stabilization and protection of shorelines from erosive wave action. The picture on the left shows smooth cordgrass planted by BEI on the fringe of a levee constructed by the Corps of Engineers for placement of dredge material. After the smooth cordgrass propagates along the shoreline of the levee, it will absorb erosive wave action and will offer excellent habitat for juvenile fish and other marine organisms. The picture below shows a levee planted by BEI at the Texas Parks & Wildlife marsh restoration project near Goose Island State Park in Aransas County, Texas. This levee was planted with smooth cordgrass and marshhay cordgrass (Spartina patens). As the picture shows, both species have successfully established and propagated and are providing erosion protection and valuable wetland habitat.
