Salt marsh
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. Salt marshes play a large role in the aquatic food web and the delivery of nutrients to coastal waters. They also support terrestrial animals and provide coastal protection.
