Shoreline Habitat Classification
Estuarine, intertidal, reef, partly enclosed, eulittoral
This common category includes marsh "islands" that develop near the mouth of broad river channels and near deltas, where marsh vegetation colonizes the substrate and provides some stability. The type of marsh vegetation varies with intertidal elevation and salinity. Substrata may be mud, peat, sand (near river channels) and clay.
