This forest, dominated by <i>Quercus montana</i>, occurs mainly on resistant ridges (monadnocks) over felsic rock of the Piedmont from North Carolina to Alabama. Soils that are well-drained, acidic and nutrient-poor contribute to low species richness. <i>Quercus montana</i> is dominant or codominant in some occurrences with <i>Quercus alba</i>. Other canopy species include <i>Quercus falcata, Carya tomentosa, Quercus marilandica, Quercus coccinea, Nyssa sylvatica, Acer rubrum, Pinus echinata</i>, and <i>Quercus stellata</i>. The subcanopy is dominated by <i>Oxydendrum arboreum</i> with <i>Cornus florida</i>. The herb and shrub layers are sparse, with <i>Vitis rotundifolia</i> as a typical component. |

This open- to closed-canopy swamp forest occurs on fresh tidal rivers from Delaware to Virginia and is best developed in the Chesapeake Bay drainage. It occurs at the upper reaches of tidal influence (and somewhat beyond in some cases) and generally receives diurnal or irregular tidal flooding. The canopy is dominated by few tree species, generally <i>Fraxinus profunda, Fraxinus pennsylvanica</i>, and <i>Nyssa biflora</i>. Other canopy associates vary among occurrences and often include <i>Nyssa sylvatica, Acer rubrum, Liquidambar styraciflua, Magnolia virginiana, Ulmus americana</i>, and <i>Pinus taeda</i>. The shrub layer is well-developed and includes <i>Lindera benzoin, Clethra alnifolia, Eubotrys racemosa, Ilex verticillata, Ilex opaca, Ilex laevigata, Alnus serrulata, Rhododendron viscosum, Viburnum dentatum, Viburnum nudum, Viburnum recognitum, Viburnum prunifolium, Amelanchier canadensis, Morella cerifera, Vaccinium corymbosum, Vaccinium fuscatum, Itea virginica, Rosa palustris, Magnolia virginiana</i>, and <i>Cornus foemina</i>. <i>Alnus maritima</i> is also characteristic in Outer Coastal Plain stands in Maryland and Delaware. Vines may be dense and include <i>Smilax rotundifolia, Smilax laurifolia, Toxicodendron radicans, Apios americana, Parthenocissus quinquefolia, Bignonia capreolata</i>, and <i>Dioscorea villosa</i>. The herbaceous layer is variable in composition and richness. Common associates include <i>Polygonum arifolium, Polygonum sagittatum, Peltandra virginica, Saururus cernuus, Carex bromoides, Impatiens capensis, Boehmeria cylindrica, Carex intumescens, Leersia oryzoides, Commelina virginica, Cicuta maculata, Arisaema triphyllum, Thalictrum pubescens, Thelypteris palustris, Woodwardia areolata, Carex stricta, Zizania aquatica, Cinna arundinacea, Osmunda cinnamomea</i>, and <i>Osmunda regalis</i>. The invasive exotic <i>Murdannia keisak</i> can also occur in this association. In addition, stands that have suffered significant loss of canopy trees (presumably due to stress from sea-level rise) may be intermediate in appearance and composition between swamp forest and herbaceous marsh. This association is differentiated from tidal swamps to the north by the presence of species of southern affinity, including <i>Magnolia virginiana, Nyssa biflora</i>, and <i>Pinus taeda</i>. |

This is a low-elevation montane or submontane alluvial forest which is found on large alluvial flats and high terraces along large rivers (e.g., Little Pigeon River) or on small, disturbed flats along medium-sized perennial streams. It is found at lower elevations in the southern fringes of the Southern Blue Ridge Province, or in the adjacent Piedmont and Southern Ridge and Valley. It often occurs on sites that were formerly cleared for farming or settlement. Soils are typically deep, loamy silts but can have large rocks and cobbles. In the Great Smoky Mountains, the mean elevation of samples is 510 m (1680 feet), ranging from 450 to 580 m (1480-1900 feet). It would be possibly expected at lower elevations as well, especially in the adjacent ecoregions. This forest has an open to closed canopy dominated by <i>Liquidambar styraciflua</i> and <i>Liriodendron tulipifera</i>, often with <i>Platanus occidentalis</i>. It is distinguished from other kinds of Montane Alluvial Forests by the dominance or relatively higher importance of <i>Liquidambar styraciflua</i> in its stands, and by its habitat on larger, lower-elevation, riverine situations. <i>Platanus</i> is characteristic, but not necessarily dominant in stands of this association. In habitats with a more calcareous influence in the substrate, <i>Juglans nigra</i> may have a higher relative importance or even be codominant. The subcanopy is absent to well-developed. Typical dominants are <i>Carpinus caroliniana, Cornus florida</i>, and <i>Acer rubrum</i>. The shrub stratum is absent to moderately dense. <i>Rhododendron maximum</i> and <i>Tsuga canadensis</i> are the most common shrubs, although other species can be present. Herbaceous cover is often absent or sparse, with ground cover dominated by litter and duff. On smaller streams, near open fields or where animal grazing is evident, herbaceous cover can approach 100% cover. Species often present with high coverage include <i>Amphicarpaea bracteata, Ageratina altissima var. altissima, Dichanthelium boscii, Thelypteris noveboracensis</i>, and <i>Toxicodendron radicans ssp. radicans</i>. Stands found on small, disturbed flats along medium-sized perennial streams may contain patches of <i>Xanthorhiza simplicissima</i>. The exotic grass <i>Microstegium vimineum</i> may have high cover in some stands. |

This shrubland association occurs on gentle to steep southwest- and southeast-facing slopes at low elevations between 2 and 496 m. It is characterized by strong dominance of <i>Encelia californica</i> in the shrub layer and a scattering of mostly non-native species in the herbaceous layer. The emergent tree layer is usually absent. |

This forested community occurs in poorly drained to permanently wet depressions surrounded by upland or saturated wetland communities, primarily pine flatwoods, but it rarely can occur in floodplain depressions of blackwater rivers (i.e., Styx River, Baldwin County, Alabama). Examples often have a characteristic dome-shaped appearance resulting from the largest, highest trees occurring in the center with smaller trees around the margins. It occurs in peaty depressions on the Coastal Plain from North Carolina and South Carolina through Georgia, Florida, Alabama, and Mississippi to eastern Louisiana. This community occurs on acidic sand overlain by an organic layer. Size ranges from one to several hundred acres. <i>Taxodium ascendens</i> is the most conspicuous tree in the canopy; <i>Pinus elliottii var. elliottii</i> can sometimes be present or codominant. <i>Nyssa biflora</i> frequently occurs in the subcanopy but may occur as a canopy species. Shrubs occur on hummocks which form around cypress buttresses and knees. This stratum may be made up of one or several species of <i>Eubotrys racemosa, Cyrilla racemiflora, Itea virginica, Lyonia lucida, Litsea aestivalis, Hypericum fasciculatum, Clethra alnifolia, Morella cerifera, Ilex cassine, Cephalanthus occidentalis, Persea palustris</i>, and more. Shrubs form a distinct understory with increasing distance from the center depression. <i>Carex</i> spp. and <i>Sphagnum</i> spp. occur on the thin, peaty muck. Other ground cover is scattered on hummocks, and includes <i>Woodwardia virginica, Saururus cernuus</i>, and <i>Lachnanthes caroliana</i>. Density increases with proximity to the community's edge. <i>Pieris phillyreifolia</i>, an epiphytic shrub-vine may occur on the <i>Taxodium ascendens</i> trees, and <i>Tillandsia usneoides</i>, are often abundant in some parts of the range. |
