Description:
These deciduous or mostly deciduous edaphically maintained woodlands are known from the Southern Blue Ridge of Tennessee and Virginia, possibly ranging into the adjacent Ridge and Valley. These woodlands occur as small openings on steep slopes, below 3000 feet elevation, on outcrops with mixtures of calcareous shales, siltstones, and sandstones. These xeric woodlands have canopies typically dominated by Carya glabra, Fraxinus americana, and Quercus prinus. In addition, Ulmus alata, Carya carolinae-septentrionalis, Quercus rubra and Juniperus virginiana var. virginiana may also be present in the canopy. Shrub cover can be sparse to moderately dense. Typical shrubs include Philadelphus hirsutus and Ostrya virginiana. Other shrubs and small trees may include Acer leucoderme, Cornus florida, Celtis tenuifolia, Staphylea trifolia, Cercis canadensis, Chionanthus virginicus, Ulmus rubra, Ptelea trifoliata, and Symphoricarpos orbiculatus. The ground cover is sparse, with large areas of bare substrate common. Coverage by mosses and lichens can be substantial. Characteristic herbaceous species include Dichanthelium boscii, Muhlenbergia tenuifolia, Packera obovata (= Senecio obovatus), Asclepias quadrifolia, Erigeron pulchellus, Polygala paucifolia, Arabis laevigata, Campanula divaricata, and Aristolochia serpentaria. Additional herbs from a stand assigned here from the Ocoee River Gorge (Tennessee) include Chasmanthium latifolium, Solidago sphacelata, Carex purpurifera, and Symphyotrichum oblongifolium (= Aster oblongifolius) (these dominant to frequent), as well as Asplenium platyneuron, Carex laxiflora, Carex pensylvanica, Cheilanthes lanosa, Dichanthelium sp., Euphorbia corollata, Geum sp., Heuchera sp., Oxalis grandis, Rudbeckia triloba, Sedum nevii, Senna marilandica, Tradescantia sp., Verbesina occidentalis, and Verbesina virginica. The exotic grass Microstegium vimineum may also be present in stands of this association.
