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

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.
Borders of forests, clearings and shrubby thickets.
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.
Salt-pruned forests and shrub thickets behind coastal dunes.
Forests between dry and moist, often oak-hickory on slopes.
Forests on moist but not wet ground, such as rich slopes and ravines.
Flat, sandy Coastal Plain pine woodlands, wetter than sandhills and denser than savannas.
Open, fire-kept longleaf pine stands over grasses and wildflowers on wet to moist sandy soil.
Roadsides, fields and disturbed ground
Ground opened by people: roadsides, old fields, pastures, fencerows and lots.
Tree plantations and managed pine
Planted or intensively managed stands of pine or hardwoods grown for timber; a land use rather than a natural community.
