General information
Provisional. A provisional ecological site description has undergone quality control and quality assurance review. It contains a working state and transition model and enough information to identify the ecological site.
MLRA notes
Major Land Resource Area (MLRA): 136X–Southern Piedmont
This area is in North Carolina (29 percent), Georgia (27 percent), Virginia (21 percent), South Carolina (16 percent), and Alabama (7 percent). It makes up about 64,395 square miles (166,865 square kilometers). (Ag Bulletin 296)
The northeast-southwest trending Piedmont ecoregion comprises a transitional area between the mostly mountainous ecoregions of the Appalachians to the northwest and the relatively flat coastal plain to the southeast. It is a complex mosaic of Precambrian and Paleozoic metamorphic and igneous rocks with moderately dissected irregular plains and some hills. (EPA Ecoregions descriptions)

Classification relationships
A PROVISIONAL ECOLOGICAL SITE is a conceptual grouping of soil map unit components within a Major Land Resource Area (MLRA) based on the similarities in response to management. Although there may be wide variability in the productivity of the soils grouped into a Provisional Site, the soil vegetation interactions as expressed in the State and Transition Model are similar and the management actions required to achieve objectives, whether maintaining the existing ecological state or managing for an alternative state, are similar. Provisional Sites are likely to be refined into more precise group during the process of meeting the APPROVED ECOLOGICAL SITE DESCRIPTION criteria.
This PROVISIONAL ECOLOGICAL SITE has been developed to meet the standards established in the National Ecological Site Handbook. The information associated with this ecological site does not meet the Approved Ecological Site Description Standard, but it has been through a Quality Control and Quality Assurance processes to assure consistency and completeness. Further investigations, reviews and correlations are necessary before it becomes an Approved Ecological Site Description.
Ecological site concept
This site occurs on occasionally flooded sandy flood plains in the mesic portion of the Southern Piedmont MLRA. Characteristic overstory trees of the site are Platanus occidentalis, Fraxinus pennsylvanica, Celtis laevigata, and Acer negundo. Other frequent or abundant species include Liquidambar styraciflua, Liriodendron tulipifera, Ulmus americana, and Carya cordiformis. Frequent understory trees include Carpinus caroliniana ssp. caroliniana, Asimina triloba, Cornus florida, and canopy species. The shrub layer is often moderate to dense, with Lindera benzoin, Arundinaria gigantea, Aesculus sylvatica, Asimina triloba, Ilex decidua, or the exotic shrub Ligustrum sinense abundant. Vines are often abundant. The herbaceous layer is usually dense. Elymus virginicus or Chasmanthium latifolium often dominate. Other frequent herbs include Boehmeria cylindrica, Carex spp. Galium aparine, Polygonum virginianum (= Persicaria virginiana), Sanicula canadensis, Verbesina occidentalis, and Viola spp.
