This is a dry-mesic forest found on apparently circumneutral slopes in the Southern Blue Ridge of Tennessee (Polk County). The canopy of stands of this forest is dominated by <i>Quercus montana, Quercus rubra, Carya glabra, Carya tomentosa, Carya ovata, Fraxinus americana</i>, and <i>Ulmus alata</i>. The subcanopy and tall-shrub strata contain, in addition to some of the canopy taxa, <i>Acer rubrum, Acer saccharum, Celtis occidentalis, Cercis canadensis, Juniperus virginiana var. virginiana, Nyssa sylvatica, Ostrya virginiana</i>, and <i>Prunus serotina</i>. Some low shrubs and woody vines include <i>Euonymus americanus, Hydrangea cinerea, Philadelphus hirsutus, Rubus allegheniensis, Vaccinium arboreum, Viburnum acerifolium, Bignonia capreolata, Cocculus carolinus, Parthenocissus quinquefolia</i>, and <i>Vitis rotundifolia</i>. On some of the slopes, <i>Solidago sphacelata</i> is an aspect dominant. Other herbs include <i>Dichanthelium boscii</i> (with higher values), <i>Acalypha gracilens, Agalinis setacea, Arabis laevigata, Asclepias variegata, Asplenium platyneuron, Asplenium trichomanes ssp. trichomanes, Eurybia divaricata, Campanula divaricata, Carex sparganioides, Desmodium</i> sp., <i>Dryopteris marginalis, Eupatorium sessilifolium, Helianthus microcephalus, Heuchera americana, Penstemon canescens, Pityopsis graminifolia, Pleopeltis polypodioides ssp. michauxiana, Pycnanthemum</i> sp., <i>Sedum ternatum, Solidago juncea, Symphyotrichum</i> spp., and <i>Thaspium barbinode</i>. This association occupies extensive areas between Big Rock Island and "The Narrows" at an elevation of about 300-350 m (1025-1175 feet). It is best developed on exposed areas and convex surfaces. This is a more-or-less closed-canopy forest with some open areas where there are massive bedrock exposures or shaly areas. Upslope, this vegetation grades into <i>Pinus echinata</i> and/or <i>Pinus virginiana</i> forests and woodlands, and downslope it grades into deciduous floodplain and riverfront forests. |

This dry to dry-mesic forest of the East Gulf Coastal Plain is dominated by <i>Quercus velutina</i> with smaller amounts of <i>Quercus alba, Carya pallida</i>, and <i>Carya glabra</i>. The relatively high importance value for <i>Quercus velutina</i> is distinctive and characteristic. Other <i>Quercus</i> species may be present in the canopy (for example <i>Quercus falcata, Quercus laevis</i>, and <i>Quercus margarettae</i>) as well as <i>Pinus taeda</i> and occasional <i>Pinus palustris</i>. The precise canopy values for the codominant or associated species may depend greatly on the relative isolation from natural fire of the habitat, and the length of the fire-return time for a particular stand. The subcanopy may contain any of the canopy species. The open tall-shrub stratum includes <i>Vaccinium arboreum</i> (which may dominate), <i>Osmanthus americanus, Acer floridanum, Cornus florida</i>, and <i>Ilex opaca</i> (an occasional individual of which could enter the subcanopy). The stature and abundance of components in this stratum could vary greatly with the recent fire history. Low shrubs include <i>Vaccinium stamineum, Quercus hemisphaerica, Viburnum rufidulum, Sideroxylon lanuginosum, Diospyros virginiana, Asimina parviflora, Aesculus pavia, Liquidambar styraciflua</i>, and <i>Yucca filamentosa</i> (which may be prominent in this stratum). The sparse to patchy ground layer contains <i>Smilax pumila, Vitis rotundifolia, Gelsemium sempervirens, Danthonia sericea, Schizachyrium scoparium, Coreopsis major, Tephrosia virginiana</i>, and <i>Pteridium aquilinum var. pseudocaudatum</i>. |

The important subcanopy trees are <i>Quercus nigra, Ilex opaca</i>, and <i>Acer rubrum</i>. The shrub layer is dense and dominated by <i>Cyrilla racemiflora, Vaccinium elliottii, Vaccinium arboreum</i>, and <i>Serenoa repens</i>. The most abundant herbaceous species is <i>Mitchella repens</i>. |

This <i>Quercus alba</i>-dominated forest occurs on steep, moist slopes, over slightly calcareous or subcalcareous substrates west of the Mississippi River. The subcanopy is characterized by high levels of <i>Acer leucoderme</i> and <i>Ostrya virginiana</i>. Diagnostic herbaceous species include <i>Spigelia marilandica</i> and <i>Solidago auriculata</i>. Both the subcanopy and herbaceous species listed above are believed to indicate the rich nutrient or high pH and moisture status of this community. |

This West Gulf Coastal Plain association comprises an open to very open, typically stunted <i>Pinus palustris</i> canopy above a very open hardwood subcanopy, composed largely of <i>Quercus marilandica</i>. This type tends to have an open, herbaceous-dominated understory in which shrubs occur only sporadically. <i>Panicum virgatum</i> is the dominant herbaceous species, which along with other grasses (<i>Sporobolus</i> sp., <i>Dichanthelium</i> spp.) form a nearly continuous grassy ground cover. A number of other herbaceous species are present which are suggestive of mesic but not particularly dry conditions, especially <i>Stenanthium gramineum</i>. |

This association represents freshwater aquatic vegetation of the Florida Peninsula, documented from the Ocala National Forest. It occupies large, clear water, spring-fed streams, forming beds in freshwater "spring runs." Stands are dominated or codominated by <i>Stuckenia pectinata</i>, with <i>Vallisneria americana</i>. Other characteristic species include <i>Najas guadalupensis</i>. The precise geographical and conceptual boundary between this and the equivalent Florida Panhandle type, ~<i>Sagittaria kurziana - Potamogeton illinoensis - Vallisneria americana</i> Aquatic Vegetation (CEGL004332)$$, is not entirely clear. |
