Description:
Woodlands in this alliance have ~Fraxinus americana$ and ~Carya glabra$ as typical canopy dominants, although ~Juniperus virginiana, Quercus prinus$, or other ~Carya$ spp. may have significant coverage in some associations. Some associations have a nearly closed or locally closed canopy, and could in some cases as readily be considered as forests, while others have an edaphically maintained woodland physiognomy. Other minor canopy species vary with geography, but may include ~Quercus rubra var. rubra, Pinus virginiana, Ulmus alata, Quercus stellata, Carya ovata$, and ~Carya pallida$. Subcanopy and shrub species are variable between associations, but can include ~Amelanchier sanguinea, Ceanothus americanus, Celtis tenuifolia, Cercis canadensis, Chionanthus virginicus, Crataegus$ sp., ~Hypericum prolificum, Juniperus virginiana var. virginiana, Lonicera flava, Ostrya virginiana, Philadelphus hirsutus, Physocarpus opulifolius, Ptelea trifoliata, Rhus aromatica var. aromatica, Rhus typhina, Rosa carolina, Spiraea betulifolia var. corymbosa, Symphoricarpos orbiculatus, Toxicodendron radicans, Vaccinium arboreum, Vaccinium pallidum, Vaccinium stamineum, Viburnum rafinesquianum (= var. rafinesquianum)$, and ~Viburnum rufidulum$. Herbaceous species vary among associations, but species known from these woodlands include ~Allium cuthbertii, Andropogon gerardii, Andropogon gyrans, Andropogon ternarius, Anemone berlandieri, Anemone virginiana, Antennaria virginica, Aquilegia canadensis, Arabis canadensis, Arabis hirsuta var. pycnocarpa (= Arabis hirsuta var. adpressipilis), Arabis laevigata, Aristida purpurascens, Aristolochia serpentaria, Asclepias quadrifolia, Asplenium platyneuron, Symphyotrichum oblongifolium (= Aster oblongifolius), Symphyotrichum patens var. patens (= Aster patens var. patens), Campanula divaricata, Cardamine parviflora var. arenicola, Carex pensylvanica, Cheilanthes lanosa, Claytonia virginica, Coreopsis major, Coreopsis pubescens, Cunila origanoides, Danthonia compressa, Danthonia sericea, Danthonia spicata, Desmodium rotundifolium, Dichanthelium boscii, Dichanthelium scoparium, Dodecatheon meadia, Draba ramosissima, Elymus hystrix, Erigeron pulchellus, Helianthus divaricatus, Helianthus microcephalus, Houstonia longifolia, Hypericum gentianoides, Hypericum punctatum, Melica mutica, Muhlenbergia tenuiflora, Phacelia dubia, Phlox nivalis ssp. hentzii, Piptochaetium avenaceum, Polygala paucifolia, Polygonum tenue, Pycnanthemum incanum, Pycnanthemum montanum, Saxifraga michauxii, Schizachyrium scoparium, Sedum glaucophyllum, Selaginella rupestris, Packera millefolia (= Senecio millefolium), Packera obovata (= Senecio obovatus), Solidago arguta var. harrisii (= Solidago harrisii), Solidago juncea, Solidago nemoralis, Sorghastrum nutans, Tradescantia ohiensis, Verbesina occidentalis, Woodsia ilvensis$, and ~Woodsia obtusa$. These woodlands are often a physiognomic complex of woodland, grassland, and rock outcropping, often associated with granitic domes or rocky summits. Soils are circumneutral and derived from such base-rich rocks as greenstone, plagioclase-rich granite, hornblende gneiss, amphibole gneiss, limestones, or calcareous shales. Woodlands in this alliance are currently defined from 1000-3800 feet elevation in the southern and central Blue Ridge, the Ridge and Valley of Virginia, and the upper Piedmont of Georgia, North Carolina, and Virginia.
