This association covers bottomland forests of the southern Piedmont of Georgia and South Carolina, the Piedmont-Ridge and Valley transition region of Alabama, the adjacent Upper East Gulf Coastal Plain of Georgia, and the Southern Ridge and Valley of Georgia and Tennessee. Stands occur in broad flat floodplains of medium-sized rivers, or as smaller occurrences along creeks and their adjacent floodplains. The diverse canopy is primarily composed of bottomland terrace species, but may also contain some levee species which would normally sort out better along a hydrologic gradient in the larger floodplains of the Coastal Plain. The canopy of stands is typically dominated by <i>Quercus shumardii</i> and <i>Quercus michauxii</i> with <i>Liquidambar styraciflua</i> and <i>Quercus nigra</i>. This type is found either in the outer edges of the Piedmont, in the transition area to the Ridge and Valley, or just barely coastward of the Fall-line, so <i>Quercus pagoda</i> is either not present at all, or if present it is at very low frequency. Other canopy and/or subcanopy species may include <i>Acer floridanum, Liriodendron tulipifera, Tilia americana var. heterophylla, Carya cordiformis</i> (which may have high cover), <i>Carya carolinae-septentrionalis, Juglans nigra, Quercus phellos</i>, and <i>Pinus taeda</i>. Occasionally, <i>Celtis laevigata, Platanus occidentalis</i> or <i>Betula nigra</i> may be present at low values, but they are not characteristic and may signal the start of a different bottomland community type when noted in large quantities. The rare tree <i>Quercus oglethorpensis</i> may be present within its limited range in the driest versions of this community (e.g., in Elbert and Wilkes counties of Piedmont Georgia and Greenwood and McCormick counties of Piedmont South Carolina). Shrubs include <i>Arundinaria gigantea</i> (which may be dominant in some stands), <i>Lindera benzoin, Ilex decidua, Callicarpa americana</i>, and <i>Corylus americana</i>. Woody vines may be prominent in stands. The herb stratum is fairly diverse. |

Sparganium americanum - (Sparganium erectum ssp. stoloniferum) - Epilobium leptophyllum Herbaceous Vegetation

This vegetation occupies marshes and impoundments within small rivers or streams with seasonal flooding, especially in areas currently or formerly flooded by beavers or restricted by natural bedrock or boulder accumulation. Most sites were heavily altered by logging in the late 1800s through the early 1900s, and this disturbance may have altered the distribution, cover, and physiognomy of these wetlands. Soils are variable and may consist of poorly to very poorly drained muck or organic-rich loamy soils of varying texture. <i>Sparganium americanum</i> strongly dominates the dense herb layer at many sites, although at some locations in the Allegheny Mountains and on the Cumberland Plateau, it is replaced by <i>Sparganium erectum ssp. stoloniferum</i>. Common associates vary with geography and include <i>Agrostis hyemalis, Callitriche heterophylla, Carex scoparia, Carex gynandra, Carex lurida, Carex stipata, Eleocharis obtusa, Epilobium coloratum, Epilobium leptophyllum, Galium tinctorium, Glyceria melicaria, Glyceria striata, Hydrocotyle americana, Hypericum mutilum, Impatiens capensis, Juncus effusus, Leersia oryzoides, Ludwigia palustris, Lycopus uniflorus, Poa palustris, Polygonum hydropiperoides, Polygonum sagittatum, Polygonum punctatum, Potamogeton</i> spp., <i>Scirpus cyperinus, Scirpus hattorianus, Scutellaria lateriflora, Solidago rugosa, Sphenopholis pensylvanica</i>, and <i>Symphyotrichum prenanthoides (= Aster prenanthoides)</i>. More locally, <i>Glyceria grandis</i> is an abundant grass. A very sparse shrub layer may be present. |
