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.
Open, wet, seepage-fed bogs of the Coastal Plain and Sandhills, often with pitcher plants.
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.
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.
