A salt marsh is a coastal ecosystem characterized by salt-tolerant plants, such as cordgrass and pickleweed, that thrive in intertidal zones. These areas are regularly flooded by tidal waters, creating a unique habitat that supports diverse wildlife, including birds, fish, and invertebrates. Salt marshes play a crucial role in protecting coastlines from erosion and filtering pollutants from water. Salt marshes are found in temperate and tropical regions around the world, often adjacent to estuaries and coastal bays. They provide essential services, such as carbon storage and nursery grounds for marine species. Additionally, they serve as important areas for recreational activities and research on coastal ecology.
