Where it lives
The places its habitat model includes. It is not found everywhere a habitat occurs.
Habitats in Virginia 12
Each habitat page lists the plants and wildlife also found there.




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.
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.
Flat, poorly drained uplands and terraces with oaks, sweetgum and sometimes loblolly pine, wet in winter and dry in summer, but neither a floodplain nor a swamp.
Wet, open, peaty mountain wetlands fed by seepage, often with sphagnum moss.
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.
