Description:
This barrens or post oak openings community is found in the midwestern United States in southern Indiana and Ohio. Stands occur on rolling hill-and-swale topography over limestone or shale bedrock. The soils are stony and excessively well-drained. This is a prominent community on the Mitchell Karst Plain in south-central Indiana. There, it occurs on rolling hill-and-swale topography on a large sinkhole plain over limestone bedrock. Soils are formed from chert residue left from the erosion of limestone bedrock. These soils are stony, acidic, and excessively well-drained. In Ohio, this community occurs in the unglaciated Bluegrass Region, north of West Union in Adams County, where it is found only over Crab Orchard Shale, on slight slopes or mounded outcrops. On slopes, deep erosional gullies are usually present. Crab Orchard Shale is calcareous and weathers to a light brown to yellowish heavy silt loam containing scattered pieces of dolomite. Fire, drought and grazing are factors in maintaining the open woody character of this type. Vegetation may be sparse, consisting of xeric species and stunted individuals of species that reach considerable size elsewhere. Graminoids, such as <i>Schizachyrium scoparium</i> and <i>Sorghastrum nutans</i>, form most of the vegetation cover in this community, but tree canopy species may include <i>Juniperus virginiana var. virginiana, Quercus alba, Quercus imbricaria, Quercus marilandica, Quercus stellata</i>, and <i>Quercus velutina</i>. Herbaceous species which may be present include <i>Aconitum uncinatum, Allium cernuum, Andropogon gerardii, Aristida longispica, Asclepias amplexicaulis, Carex meadii, Danthonia spicata, Eryngium yuccifolium, Euphorbia corollata, Helianthus mollis, Helianthus hirsutus, Houstonia</i> sp., <i>Liatris cylindracea, Liatris squarrosa, Lobelia spicata, Panicum flexile, Pycnanthemum tenuifolium, Rudbeckia hirta, Salix humilis, Silphium trifoliatum</i>, and <i>Sporobolus vaginiflorus</i>.
