Description
Definition Salt marshes dominated by herbaceous, emergent vegetation and forb-like dwarf shrubs; areas are infrequently flooded by tides and characterized by distinctive patterns of halophytic vegetation (e.g., Spartina patens). Low shrubs may be present, but they are not dominant. Shrub-dominated portions of salt marshes are included in the Saltwater Tidal Scrub-Shrub Wetland Biotic Group. The list of biotic communities for this group is long: a few examples are provided below, and the complete list is available in Appendix F.
