These montane woodlands of the Southern Blue Ridge are currently known from the lower mountains of North Carolina and Georgia, at 750-1150 m (2500-3800 feet) elevation, on sites with biotite gneiss geology with veins of base-rich hornblende gneiss. They have open and stunted canopies (3-8 m tall), with or without gnarly <i>Juniperus virginiana var. virginiana</i> and various deciduous species, typically <i>Carya glabra, Fraxinus americana, Quercus montana, Ostrya virginiana</i>, and <i>Chionanthus virginicus</i>. Occasionally, <i>Pinus virginiana</i> may be a component of the canopy mix. Occurrences are often physiognomic complexes of woodland, grassland, and rock outcropping, and are often associated with southern or eastern exposures on granitic domes or rocky summits. Some occurrences lack <i>Juniperus virginiana</i> but retain the same suite of species that are indicative of high base status rock. Shrubs are scattered or locally abundant and may include <i>Ptelea trifoliata, Physocarpus opulifolius, Hypericum prolificum, Vaccinium stamineum, Vaccinium pallidum, Lonicera flava, Amelanchier sanguinea</i>, and <i>Rosa carolina</i>. A dense, grassy herb layer can occur beneath the canopy or in open areas, interspersed with bare rock. Typical dominants include <i>Carex pensylvanica, Dichanthelium scoparium, Danthonia compressa, Danthonia sericea, Andropogon gyrans, Andropogon ternarius, Andropogon gerardii, Sorghastrum nutans, Schizachyrium scoparium var. scoparium, Aristida purpurascens</i>, and <i>Melica mutica</i>. Other herbaceous species can include <i>Dodecatheon meadia, Solidago nemoralis, Pycnanthemum curvipes, Pycnanthemum montanum, Hypericum punctatum, Hypericum gentianoides, Desmodium rotundifolium, Antennaria virginica, Piptochaetium avenaceum, Packera millefolium, Helianthus microcephalus, Claytonia virginica, Coreopsis major</i>, and <i>Coreopsis pubescens</i>. The steepest areas may have patches of <i>Sedum glaucophyllum, Houstonia longifolia</i>, and <i>Saxifraga michauxii</i>. |

This association includes upper marsh edges and flats strongly dominated by <i>Borrichia frutescens</i>, ranging in size from narrow bands to flats in excess of 500 ha. It is broadly described to include vegetation ranging from the Mid- and South Atlantic Coast to the West Gulf Coast of the United States. Other characteristic species may include <i>Spartina patens, Iva frutescens</i>, and <i>Limonium carolinianum</i>. In Texas, the composition of this low-diversity, irregularly tidally flooded shrubland is variable and can include <i>Distichlis spicata, Bolboschoenus robustus, Sporobolus virginicus, Monanthochloe littoralis, Atriplex matamorensis</i> (in south Texas), <i>Sarcocornia pacifica, Limonium carolinianum, Lycium carolinianum var. quadrifidum, Rayjacksonia phyllocephala, Prosopis reptans</i> (in south Texas), and <i>Batis maritima</i>. Here, this community often occurs just above the lower tidal flat communities ~<i>Batis maritima - Sarcocornia pacifica</i> Saline Dwarf-shrubland (CEGL003956)$$ or ~<i>Sarcocornia pacifica - (Batis maritima, Distichlis spicata)</i> Saline Dwarf-shrubland (CEGL002278)$$.<br /><br />This shrubland usually occurs as a very narrow band adjacent and below tidal shrublands. Two large examples of this association at Fort Pulaski, Georgia, are extensive enough to map and occur on tidal flats adjacent the extensive salt marsh communities of eastern Cockspur Island. Typically this community is monospecific, being made up almost exclusively of <i>Borrichia frutescens</i>. |

This dunegrass association occurs on ocean front dunes on barrier islands and barrier spits in the Mid-Atlantic Coastal Plain, from southeastern Virginia to South Carolina and possibly Georgia. <i>Uniola paniculata</i> is the dominant species, with <i>Schizachyrium littorale</i> and <i>Panicum amarum</i> also common and characteristic. <i>Ammophila breviligulata</i> may be common in Dare and Currituck counties of northeastern North Carolina, and in southeastern Virginia. Other typical species include <i>Croton punctatus, Oenothera humifusa, Physalis walteri, Hydrocotyle bonariensis, Heterotheca subaxillaris</i>, and <i>Chrysopsis gossypina</i>. This is the characteristic foredune vegetation immediately south and north of the Outer Banks of North Carolina, perhaps associated with slightly loamier soils with more influence of riverine sediments. |

This barrens community occurs on steep slopes with exposed outcrops of calcareous sedimentary, metasedimentary, and metamorphic rocks of the Central Appalachians. In the Ridge and Valley province, underlying bedrock includes calcareous shales of the Jennings, Hampshire, Martinsburg, and Brallier formations, and less commonly calcareous Silurian sandstones. Blue Ridge sites are underlain by Catoctin Formation metabasalt, amphibolite, and Harpers Formation metasiltstone and phyllite. Habitats are on steep, southeast - to southwest-facing slopes at elevations from 170 to 580 m (550-1900 feet). On sites underlain by shale, soils are thin but generally better developed than other shale-barren associations. Mafic-rock sites typically have high cover (about 50%) of exposed bedrock outcrops with some areas of shallow soil development. Sandstone sites generally consist of steep, continuous pavements with thin veneers and pockets of soil. Soils from all substrates have high calcium levels; those weathered from metabasalt and amphibolite also have high magnesium and manganese levels. A patchy overstory of stunted trees may ameliorate to some degree the otherwise xeric conditions imposed by exposure and slope. Canopy closure is usually less than 30%, occasionally higher, and tends to be patchy, with herbaceous openings. Shrubs are sparse at most known locations. The herbaceous layer forms 25-90% ground cover. The canopy is codominated by <i>Juniperus virginiana</i> and <i>Fraxinus americana</i>, with other associates including <i>Carya glabra, Quercus montana, Quercus stellata, Celtis tenuifolia, Amelanchier arborea, Quercus rubra</i>, and <i>Pinus virginiana</i>. <i>Rhus aromatica</i> is a characteristic shrub. The herbaceous layer is very diverse. <i>Carex pensylvanica</i> is constant and dominant. <i>Danthonia spicata</i> is frequent but sparse. Other characteristic species include <i>Cheilanthes lanosa, Woodsia obtusa, Phacelia dubia, Deschampsia flexuosa, Solidago arguta var. harrisii, Schizachyrium scoparium, Phlox subulata, Silene antirrhina, Elymus hystrix, Tradescantia virginiana, Helianthus divaricatus, Polygonum scandens var. cristatum, Polygonatum biflorum, Triodanis perfoliata, Pycnanthemum incanum, Allium cernuum</i>, and <i>Arenaria serpyllifolia</i>. This association is distinguished from other shale-barren types by its open physiognomy, occurrence on circumneutral to calcareous rock at low to moderate elevations, and the frequency of several characteristic herbs including <i>Cheilanthes lanosa, Phacelia dubia, Tradescantia virginiana</i>, and <i>Triodanis perfoliata</i>. In addition, <i>Fraxinus americana</i> and <i>Celtis tenuifolia</i> occur at a higher frequency in this association than in other shale-barren types. |

This community is a low- to moderate-statured, broad-leaved evergreen forest that is often, though not always, sculpted into streamlined forms by wind-borne salt spray due to proximity to the Atlantic Ocean, especially on barrier islands. This type ranges from southeastern Virginia to South Carolina (and possibly Georgia). Canopies are dominated by <i>Quercus virginiana</i> and <i>Quercus hemisphaerica</i> with lesser amounts of <i>Pinus taeda</i> and <i>Juniperus virginiana var. silicicola</i>. Subcanopy and shrub layers are well-developed and vines are typically abundant. The herb layer is sparse and low in diversity. Typical understory components include <i>Persea borbonia, Carpinus caroliniana ssp. caroliniana, Juniperus virginiana var. silicicola, Cornus florida, Osmanthus americanus var. americanus, Ilex opaca var. opaca</i>, and <i>Zanthoxylum clava-herculis</i>. Shrub species include <i>Ilex vomitoria, Morella cerifera, Sabal minor</i>, and <i>Callicarpa americana</i>. Dominant vines are <i>Toxicodendron radicans, Vitis rotundifolia, Smilax</i> spp., <i>Parthenocissus quinquefolia, Bignonia capreolata, Berchemia scandens, Nekemias arborea</i>, and <i>Gelsemium sempervirens</i>. Typical herbs are <i>Mitchella repens, Asplenium platyneuron var. platyneuron, Chasmanthium laxum, Piptochaetium avenaceum, Galium pilosum, Dichanthelium commutatum, Elephantopus nudatus</i>, and <i>Passiflora lutea</i>. This community occurs on sand flats, lower slopes, and on stabilized dunes that are protected from saltwater flooding but experience light to moderate salt spray. |
