Estuarine Intertidal Sand: Partly Enclosed Eulittoral, Euhaline (Marsh)

This is a common habitat often associated with spits, berms or deltas where sand collects, where either there is little freshwater influence or marine derived salts are concentrated through evaporation. Substrata are sand, silty sand, or gravelly sand.  Salt pannes are common.

Diagnostic Species
