Name: Quercus alba - (Quercus velutina) / Lespedeza virginica - Eupatorium hyssopifolium Woodland Reference: Eastern Ecology Working Group of... Description: This oak barrens community of the unglaciated Western Allegheny Plateau (and small portions in the glaciated portion of the ecoregion) occurs on moderate to steep hillside slopes and more level to gently rolling ridgetops with southern or southwestern exposure. Soils are generally acidic derived from Mississippian and Pennsylvanian age sandstones and conglomerates. Shallow, droughty, sandy loam soils tend to occupy the slopes, while a more heavy-textured silt loam is found on the ridges. Bedrock is often exposed at the surface. Seepage zones from the porous bedrock may be present. Dominant canopy species are usually <i>Quercus alba</i> and <i>Quercus velutina</i> with <i>Quercus coccinea, Acer rubrum</i>, and <i>Carya</i> spp. Other canopy associates may include <i>Quercus stellata, Quercus prinus, Populus grandidentata</i>, and <i>Pinus virginiana</i>. <i>Pinus rigida</i> can be locally dominant, particularly where the Sharon conglomerate outcrops are exposed, as in Pike and Jackson counties, Ohio. The shrub layer is sparse and poorly developed, comprised of scattered patches of <i>Vaccinium pallidum</i> or <i>Gaylussacia baccata</i>. Herbaceous cover is discontinuous and may vary considerably depending on topographical position and shade cast by canopy cover. <i>Schizachyrium scoparium</i> and, less often, <i>Sorghastrum nutans</i> may dominate in open areas where soils are well-developed or on the more level ridges. <i>Schizachyrium scoparium</i> also dominates on the drought-prone, sandy soils of hillside slopes.  Accession Code: VB.CC.31259.CEGL006433 Plot-observations of this Community Concept: 0
