This association covers the widespread longleaf pine communities of dry sands and occurs mostly in the Fall-line Sandhills, where plants characteristic of the coastal fringe are absent. Stands are dominated by <i>Pinus palustris</i> with a low-diversity scrub oak layer strongly dominated by <i>Quercus laevis</i> and a well-developed herbaceous layer dominated by <i>Aristida stricta</i>. <i>Gaylussacia dumosa</i> is a common, abundant shrub component. |

This type covers forests of brownwater river floodplain terraces and ridges in the Atlantic Coastal Plain and adjacent East Gulf Coastal Plain. Stands lack a significant component of levee tree species, and the concept does not include forests on active natural levees. These are stable bottomland forests found throughout the Atlantic and adjacent East Gulf coastal plains along large or medium-sized rivers. The canopy of these forests is generally dominated by a variable mixture of <i>Quercus michauxii, Quercus pagoda, Quercus phellos, Quercus laurifolia</i>, and <i>Liquidambar styraciflua</i>. In addition, <i>Acer rubrum</i> may be abundant. Other hardwoods which may be present include <i>Fraxinus pennsylvanica, Carya ovata, Carya cordiformis, Juglans nigra</i>, and others. Subcanopy species may include <i>Carpinus caroliniana</i> (which may be dominant), <i>Ilex decidua, Asimina triloba</i>, and <i>Ilex opaca var. opaca</i>. The understory is typically dominated by <i>Carpinus caroliniana</i>. Patches of <i>Arundinaria gigantea</i> may be common in places. <i>Vaccinium elliottii</i> and <i>Vaccinium formosum</i> may be the most constant shrubs. Some other frequent species include <i>Mitchella repens</i> and <i>Vitis rotundifolia</i>. Included here are topographically intermediate examples that lack a significant pine component. |

These forests occur along medium, and possibly large, Piedmont rivers, on floodplains or terraces that are elevated several meters above the river. They occur on sites that are higher above the river, less frequently flooded, and better drained than other floodplain communities. They are dominated primarily by bottomland hardwood species, but usually have a significant component of upland species present as well. <i>Liquidambar styraciflua, Quercus phellos, Quercus michauxii, Quercus nigra, Quercus pagoda</i>, and <i>Acer floridanum</i> predominate, but <i>Quercus alba, Carya ovata, Carya cordiformis, Carya tomentosa, Quercus shumardii, Liriodendron tulipifera</i>, and <i>Fagus grandifolia</i> are also fairly common. Occasionally, species shared with levee forests, such as <i>Platanus occidentalis</i> or <i>Celtis laevigata</i>, may be present. <i>Carpinus caroliniana</i> is the most abundant understory tree. Other high constancy understory species include <i>Ilex opaca, Ulmus alata, Acer floridanum, Juniperus virginiana</i>, and <i>Asimina triloba</i>. <i>Ilex decidua</i> is the most constant native shrub, but invasive exotic <i>Ligustrum sinense</i> is also usually present. Other common shrubs include <i>Lindera benzoin, Aesculus sylvatica</i>, and <i>Asimina triloba</i>. Frequent herbaceous species include <i>Chasmanthium latifolium, Mitchella repens, Polystichum acrostichoides</i>, and <i>Verbesina alternifolia</i>. <i>Microstegium vimineum</i> (exotic) also occurs with high frequency. Other herbs include both species typical of floodplains, such as <i>Boehmeria cylindrica, Carex debilis, Carex grayi</i>, and <i>Carex intumescens</i>, as well as more typical upland species such as <i>Dichanthelium commutatum</i> and <i>Danthonia spicata</i>. |

This association occurs in wetland flats, backdunes and interdune swales along the Atlantic coast from southern New Jersey to Florida. The substrate may be sand or loamy sand, sometimes with a thin layer of organic matter. It occurs beyond the reach of most storm tides but may be impacted by salt spray. The water table may often be less than half a meter below the surface, and may be dry at the end of the growing season. Canopy closure varies from densely closed to moderately open. This vegetation is dominated by <i>Morella cerifera</i>, sometimes intermixed with <i>Juniperus virginiana var. silicicola</i> (from North Carolina and possibly southern Virginia southward), <i>Morella pensylvanica</i> (from northern North Carolina northward), <i>Rhus copallinum, Baccharis halimifolia</i>, or <i>Ilex vomitoria</i>. The shrub layer can vary from 2-8 m in height. Occasionally, a sparse emergent canopy of trees (such as <i>Juniperus virginiana var. silicicola</i> or <i>Sabal palmetto</i> in the southern parts of the range) may be present. The herbaceous layer is characterized by <i>Spartina patens</i>. Other ground flora associates include <i>Toxicodendron radicans, Eupatorium capillifolium, Eupatorium hyssopifolium var. hyssopifolium, Panicum virgatum, Andropogon virginicus, Juncus dichotomus, Solidago sempervirens, Smilax</i> spp., <i>Parthenocissus quinquefolia, Vitis</i> spp., and <i>Schoenoplectus pungens</i>. Small openings may have wetland graminoids, such as <i>Juncus roemerianus, Spartina patens, Fimbristylis castanea, Andropogon glomeratus var. pumilus, Muhlenbergia filipes</i>, etc., and forbs, such as <i>Hydrocotyle bonariensis, Sabatia stellaris, Polygonum hydropiperoides, Eleocharis</i> spp., etc. In other cases, few herbs are present, because of the dense, thicket-like shrub layer. |

This oak-hickory forest occurs on well-drained loamy sand of midslopes in the northeastern United States. This vegetation is ecologically transitional between dry-rich oak-hickory forests of relatively high diversity and dry, acidic oak species-poor forests. <i>Quercus rubra, Quercus alba</i>, and <i>Quercus velutina</i> are prominent in the canopy. <i>Quercus prinus</i> and <i>Quercus coccinea</i> are canopy associates in the southern portion of the range. Typical hickory species include <i>Carya glabra, Carya ovata, Carya tomentosa</i>, and <i>Carya ovalis</i>. Other canopy associates may include <i>Acer rubrum, Sassafras albidum</i>, and <i>Amelanchier arborea</i>. At the northern range limit of this type, <i>Pinus strobus</i> and <i>Betula lenta</i> also occur as minor associates. <i>Cornus florida</i> is a characteristic understory tree in portions of the range. The shrub layer is characterized by <i>Viburnum acerifolium</i>, with other frequent associates including <i>Hamamelis virginiana, Vaccinium corymbosum, Corylus cornuta</i>, and <i>Corylus americana</i>. A short-shrub layer may be common, but is generally not abundant, and is characterized by <i>Vaccinium pallidum</i> and <i>Gaylussacia baccata</i>, with <i>Vaccinium angustifolium</i> occurring more frequently to the north. The herbaceous layer is characterized by <i>Carex pensylvanica, Carex rosea, Maianthemum racemosum, Aralia nudicaulis, Hieracium venosum, Solidago bicolor, Desmodium glutinosum, Desmodium paniculatum, Melampyrum lineare, Chimaphila maculata, Eurybia divaricata, Danthonia spicata, Aureolaria</i> spp., <i>Pteridium aquilinum, Dennstaedtia punctilobula</i>, and <i>Helianthemum canadense</i>. |
