Habitats in Florida 12
Each habitat page lists the plants and wildlife also found there.

Coastal tidal marshes (salinity not stated)




Open, wet, seepage-fed bogs of the Coastal Plain and Sandhills, often with pitcher plants.
Depression ponds and limesinks
Shallow ponds in Coastal Plain depressions, such as limesinks and the ponds in some Carolina bays, that rise and fall with the seasons.
Disturbed and introduced wetlands
Wet ground taken over by weedy or introduced plants after disturbance, such as common reed, Chinese tallow or tamarisk stands; the upland counterpart is roadsides, fields and disturbed ground.
Marshes along tidal rivers where the water is fresh but rises and falls with the tide.
Tidal forests and thickets of red, black and white mangrove along sheltered tropical and subtropical shores.
Coastal marshes flooded by salty or brackish tides.
Places where groundwater keeps the soil or rock wet, such as seepage slopes and spring runs.
