Habitats in Arkansas 9
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.
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.
Roadsides, fields and disturbed ground
Ground opened by people: roadsides, old fields, pastures, fencerows and lots.
Streams, rivers and their banks
Flowing water and its banks, bars and rocky shoals.
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.
