Low, wet, muddy area periodically or continuously flooded by brackish or salt water to a shallow depth, usually characterized by grasses and other low plants (but not trees); land transitional between terrestrial and aquatic systems where saturation with water is the dominant factor controlling plant and animal communities and soils..
Salt marsh is a key habitat of transitional waters lying at the interface between the land and the sea, depending on, and periodically covered by tidal sea water. Chapman (1960, 1977 a, b ) describes nine different geographical salt marsh regions throughout the world.
