Description:
This community includes vegetation of North Carolina's upper Piedmont and Blue Ridge, and Virginia's Southern Blue Ridge, on gently to moderately sloping, low-elevation outcrops, with irregular or undulating surfaces but few crevices, and containing plants characteristic of higher pH conditions. This community occurs as small patches (approx. 5-50 acres) at elevations below 1220 m (4000 feet). Vegetation consists of shallow mats dominated by <i>Selaginella rupestris</i> and deeper grassy mats, interspersed with areas of smooth rock or rock with few crevices or fractures. This community has few deep-rooted forbs, shrubs, or trees. The flora is diverse and characterized by the presence of plants indicative of higher pH soils, such as <i>Hylotelephium telephioides, Dodecatheon meadia, Sedum glaucophyllum, Cheilanthes lanosa, Pycnanthemum curvipes, Arabis laevigata var. laevigata</i>, and <i>Penstemon canescens</i>. Graminoids in this community include <i>Danthonia sericea, Andropogon virginicus, Carex biltmoreana, Andropogon gerardii</i>, and <i>Sorghastrum nutans</i>. Woody species may be scattered, rooted in crevices or in marginal zones between exposed rock and adjacent forests. Typical woody plants include <i>Philadelphus inodorus, Philadelphus hirsutus, Chionanthus virginicus, Quercus montana, Juniperus virginiana, Fraxinus americana</i>, and <i>Physocarpus opulifolius</i>.
