Description:
This alliance includes shortleaf pine-oak woodlands of the interior southeastern United States, ranging from the Piedmont, into the southern edge of the Southern Blue Ridge, and possibly into the Cumberland Plateau and Southern Ridge and Valley, and west into the Ozark and Ouachita Mountains. These woodlands have mixed evergreen and deciduous canopies where ~Pinus echinata, Quercus stellata$, and ~Quercus marilandica$ occur in varying ratios.. This vegetation tends to occur on edaphically and/or topographically extreme sites such as on steep and rocky south- and west-facing slopes and ridges with thin soils, although some may be on upland flats with extreme soil conditions. Canopy associates include ~Pinus virginiana, Quercus prinus, Quercus falcata, Nyssa sylvatica, Quercus alba, Quercus coccinea var. coccinea, Quercus velutina$, and other species. The trees are often stunted. Subcanopy and shrub species include ~Oxydendrum arboreum, Acer rubrum var. rubrum, Kalmia latifolia, Symplocos tinctoria, Vaccinium arboreum, Vaccinium formosum, Vaccinium pallidum, Vaccinium stamineum, Gaylussacia dumosa (= var. dumosa)$, and ~Lyonia mariana$. The herbaceous layer varies from sparse to dense and may contain ~Schizachyrium scoparium, Andropogon glomeratus var. pumilus (= Andropogon tenuispatheus), Danthonia spicata, Danthonia sericea, Iris verna var. verna, Pteridium aquilinum var. pseudocaudatum, Smilax glauca (= var. glauca)$, and ~Tephrosia virginiana$. Occurrences in the mountains likely will have ~Baptisia tinctoria, Chamaecrista fasciculata (= Cassia fasciculata), Chamaecrista nictitans (= Cassia nictitans), Ceanothus americanus, Chrysopsis mariana, Clitoria mariana, Coreopsis tripteris, Crotalaria sagittalis, Desmodium rotundifolium, Saccharum giganteum, Euphorbia corollata, Helianthus atrorubens, Helianthus microcephalus$, and ~Pityopsis aspera$ in the herbaceous layer. Species that are common on occurrences on mafic rock include ~Carya carolinae-septentrionalis, Fraxinus americana, Vaccinium arboreum, Viburnum rufidulum$, and ~Cercis canadensis var. canadensis$.
