Salt marsh

Coastal ecosystem between land and open saltwater that is regularly flooded

A salt marsh, saltmarsh or salting, also known as a coastal marsh, is a tidal wetland in the upper coastal intertidal zone between land and sea that is regularly flooded by tides of seawater or brackish water. It is a unique marine coastal ecosystem dominated by dense stands of salt-tolerant plants such as herbs, grasses, or low shrubs. These plants are terrestrial in origin and are essential to the stability of the salt marsh in trapping and binding sediments.
