Habitats in Virginia 11
Each habitat page lists the plants and wildlife also found there.

Granite and other acidic rock outcrops


Roadsides, fields and disturbed ground

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.
Glades, barrens and outcrops on limestone
Open, thin-soil openings and rock on limestone, dolomite or other lime-rich rock, including cedar glades.
Forests between dry and moist, often oak-hickory on slopes.
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.
