Depending on where the salt marsh is located ...
The high marsh is also important to many habitat specialists such as the Saltmarsh Sparrow, Black Rail, American Black Duck, saltmarsh spike-grass, and salt-hay. These specialists rely on the high marsh ecosystem to provide for their biological needs to ensure stable productivity and abundance.
An inland salt marsh is a saltwater marsh located away from the coast. It is formed and maintained in areas when evapotranspiration exceeds precipitation and/or when sodium - and chloride -laden groundwater is released from natural brine aquifers .
The littoral zone, also called litoral or nearshore, is the part of a sea, lake, or river that is close to the shore.
