Where it lives
The places its habitat model includes. It is not found everywhere a habitat occurs.
Habitats in Louisiana 7
Each habitat page lists the plants and wildlife also found there.

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.
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.
Open, herb-covered wetlands with fresh, non-tidal water.
Still water and its edges: ponds, lakes, millponds and reservoirs.
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.
