Habitats in Alabama 12
Each habitat page lists the plants and wildlife also found there.
Streams, rivers and their banks

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.
Forests and open woodlands on dry ridges and slopes, often oak or pine.
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.
Glades, barrens and outcrops on limestone
Open, thin-soil openings and rock on limestone, dolomite or other lime-rich rock, including cedar glades.
Granite and other acidic rock outcrops
Bare or thin-soil rock on granite, gneiss, sandstone, quartzite and similar acidic rock, including granite flatrocks and domes.
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.
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.
