Native Flora
- Flora changes from macroalgae in fresh and brackish waters to seagrass and mangroves as salinity increases
|
The freshwater habitats of the Everglades are dominated by marsh and slough flora, however the flora changes moving downstream where the freshwater mixes with seawater. Transitional macroalgae species including Chara hornemanni and Batophora oerstedi are common, preferring salinities from 0-10 parts per thousand (ppt).

Widgeon grass (Ruppia maritima) also prefers waters of low salinities. As salinities increase, Acetabularia crenulata, Caulerpa verticillata, and Udotea wilsoni become the dominant macroalgae along with shoal grass replacing widgeon grass. Mangrove forests and islands are also common along the shoreline and just offshore in estuarine waters.

Past the intertidal zone, turtle grass (Thalassia testudinum) becomes the dominant seagrass, forming extensive meadows that provide habitat and shelter for a diversity of marine organisms.
