Spartina alterniflora, commonly known as smooth cordgrass, is a perennial salt marsh grass native to the eastern United States and parts of South America. It thrives in intertidal zones, where it plays a crucial role in stabilizing shorelines and providing habitat for various wildlife. This grass can grow up to 2 meters tall and has long, slender leaves that are adapted to withstand saltwater and tidal fluctuations. Smooth cordgrass is essential for coastal ecosystems, as it helps filter pollutants and improve water quality. Its extensive root system prevents erosion and supports the growth of other plant species. Additionally, Spartina alterniflora serves as a food source for birds and other animals, contributing to the overall biodiversity of marsh habitats.
