Habitats in Arkansas 6
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.
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.
Still water and its edges: ponds, lakes, millponds and reservoirs.
Streams, rivers and their banks
Flowing water and its banks, bars and rocky shoals.
