Habitats in Florida 15
Each habitat page lists the plants and wildlife also found there.







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.
Floodplain and bottomland forests
Forests on low ground beside rivers and streams that flood from time to time.
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.
