Salt marshes of coastal tidal zones are grasslands dominated by perennial grasses and sedges. Distinct vegetation zones may be present, coincident with different flooding regimes. Saltmarsh cordgrass (Spartina alterniflora) dominates frequently inundated areas, whereas needle rush (Juncus roemerianus) dominates higher, less frequently flooded areas.
Mangrove swamp is a dense forest or shrubland, situated on coastal an estuarine shorelines with low wave energy. There are three mangrove species in Florida; red mangrove (Rhizophora mangle) and black mangrove (Avicennia germinans) occur within the coastal range of MLRA 154.
