Name:
Fraxinus americana - Carya glabra - Juniperus virginiana Piedmont-Appalachian Woodland Alliance
Reference:
NatureServe Biotics 2019
Description:
This alliance encompasses a variety of woodlands found in the upper Piedmont of Georgia, North Carolina, and Virginia, as well as in the adjacent Southern Blue Ridge that have <i>Carya glabra, Fraxinus americana</i>, and/or <i>Quercus</i> species (e.g., <i>Quercus alba, Quercus stellata</i>) as typical canopy dominants, although <i>Juniperus virginiana</i> may have significant coverage in some associations. Other minor canopy species vary with geography, but may include <i>Carya ovata, Carya pallida, Pinus virginiana, Quercus rubra var. rubra</i>, and <i>Ulmus alata</i>. Subcanopy and shrub species are variable among associations, but can include <i>Amelanchier sanguinea, Ceanothus americanus, Celtis tenuifolia, Cercis canadensis, Chionanthus virginicus, Crataegus</i> sp., <i>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 corymbosa, Symphoricarpos orbiculatus, Toxicodendron radicans, Vaccinium arboreum, Vaccinium pallidum, Vaccinium stamineum, Viburnum rafinesqueanum</i>, and <i>Viburnum rufidulum</i>. Herbaceous species also vary among associations. Examples are often a physiognomic complex of woodland, grassland, and rock outcrops, 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. Some associations have a nearly closed or locally closed canopy, and could in some cases as readily be considered forests, while others have an edaphically-maintained woodland physiognomy. Canopy closure is probably also dependent on natural disturbances (fire, ice and wind storms) as well as management and edaphic factors.
