Name: Pinus (virginiana, taeda) / Juniperus virginiana - Chionanthus virginicus - Ulmus alata Granitic Flatrock Border Forest Reference: NatureServe Biotics 2019 Description: This granitic flatrock border woodland occurs on shallow soils over exfoliated granitic bedrock, on the margins of Piedmont Fall-line granite outcrops (some of which are actually found east of the fall-line in the Coastal Plain). Stands are generally associated with open granitic flatrock communities. Stands of this association are somewhat open forests or woodlands. The closure of stands may be variable, and many would fall below the 60% forest/woodland threshold, but this association is placed in a "forest" alliance. The canopy is typically dominated by <i>Pinus virginiana</i> or <i>Pinus taeda</i>. Other canopy species, which also may form an open understory, include <i>Juniperus virginiana, Ulmus alata, Carya glabra, Chionanthus virginicus</i>, and <i>Quercus stellata</i>. Frequent shrubs include <i>Vaccinium arboreum</i> and <i>Rhus copallinum</i>. Other shrubs include <i>Vaccinium stamineum</i> and <i>Rhus aromatica</i>. Woody vines, especially <i>Vitis rotundifolia, Toxicodendron radicans, Smilax bona-nox</i>, and <i>Smilax rotundifolia</i>, are often abundant. Herb cover is generally low to moderate and usually includes only small amounts of the species of the open rock. Grasses, including <i>Schizachyrium scoparium, Piptochaetium avenaceum</i>, or <i>Danthonia spicata</i>, may be common. Xerophytic species such as <i>Opuntia humifusa</i> or <i>Yucca filamentosa</i> are often present, as are typical forest species such as <i>Chimaphila maculata</i> and <i>Asplenium platyneuron</i>. The understories of stands of this type may become invaded by the exotic species <i>Ligustrum sinense, Lonicera japonica, Microstegium vimineum</i>, or <i>Stellaria media</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:32842-{D08EA12A-D00F-461F-8A8B-3199ED892196} Plot-observations of this Community Concept: 16
