GLOBAL DESCRIPTION<br />

Concept Summary: This early-successional upl<strong>and</strong> forest of the southeastern U.S. occurs on a<br />

variety of environmental settings, resulting from succession following human activities such as<br />

logging <strong>and</strong> clearing or agriculture. St<strong>and</strong>s are dominated by Liquidambar styraciflua<br />

(sweetgum), sometimes to the exclusion of other species. Pinus taeda (loblolly pine) is a<br />

common associate. Other associated species are highly variable <strong>and</strong> depend on location <strong>and</strong> st<strong>and</strong><br />

history.<br />

Environmental Description: This association is found in upl<strong>and</strong>s that have been heavily<br />

impacted by agriculture or other severe disturbances <strong>and</strong> are recovering.<br />

<strong>Vegetation</strong> Description: St<strong>and</strong>s are dominated by Liquidambar styraciflua (sweetgum),<br />

sometimes to the exclusion of other species.<br />

DISTRIBUTION<br />

Range: This association may be found throughout the southeastern United States, in the coastal<br />

plains <strong>and</strong> interior ecoregions. It is also attributed to New Jersey with the merger of<br />

CEGL006927. The status in intervening states (e.g., Delaware, Maryl<strong>and</strong>) needs to be assessed.<br />

States/Provinces: AL, AR?, DE, GA, KY, LA, MD, MS, NC, NJ, OK, SC, TN, VA.<br />

Federal L<strong>and</strong>s: NPS (Big South Fork, Chickamauga-Chattanooga?, Colonial, Cowpens,<br />

George Washington Birthplace, Guilford Courthouse, Kings Mountain, Mammoth Cave,<br />

Natchez Trace, Ninety Six, Petersburg, Shiloh, Thomas Stone, Vicksburg); USFS (Cherokee?,<br />

Oconee?, St. Francis?); USFWS (Prime Hook).<br />

CONSERVATION STATUS<br />

Rank: GNA (modified/managed) (19-Aug-2002).<br />

Reasons: This is an upl<strong>and</strong> successional vegetation type composed of native species. Its<br />

conservation value is limited, but it may provide buffer for communities of greater conservation<br />

value.<br />

CLASSIFICATION INFORMATION<br />
