Habitats in Louisiana 17
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.
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.
Floodplain and bottomland forests
Forests on low ground beside rivers and streams that flood from time to time.
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.
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.
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.
Forested wetlands with standing water much of the year, such as cypress and gum swamps.
Borders of forests, clearings and shrubby thickets.
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.
Open, grass-dominated places kept open by fire, grazing or thin soil, from tallgrass prairie to Piedmont prairies.
Roadsides, fields and disturbed ground
Ground opened by people: roadsides, old fields, pastures, fencerows and lots.
