Habitats in North Carolina 12
Each habitat page lists the plants and wildlife also found there.
Floodplain and bottomland forests



Open sand of beaches, dunes and the hollows between them.
Coastal tidal marshes (salinity not stated)
Tidal marshes of the Atlantic and Gulf coasts where the source does not say whether the water is fresh, brackish or salt. A stated salinity files the marsh under freshwater tidal marshes or salt and brackish marshes instead.
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.
Coastal marshes flooded by salty or brackish tides.
Salt and brackish open water of sounds, bays and estuaries, with the mud and sand flats and seagrass beds that tides cover and uncover; the vegetated marsh is salt and brackish marshes.
Roadsides, fields and disturbed ground

Salt-pruned forests and shrub thickets behind coastal dunes.
