Reference:
NatureServe Biotics 2019
Description:
This shortleaf pine - oak woodland type is found in the central United States, in the Ozarks and Ouachita Mountains of Missouri and Arkansas, likely extending into Oklahoma. Stands occur on upper to middle, south-facing slopes, saddles, and flatter ridgelines. Soils are shallow to deep (25-100 cm), and well-drained. Parent material is a variety of sandstone and mixed sandstone/shale-derived substrates or, in parts of the Missouri Ozarks and central Ouachitas, chert substrates. The vegetation contains an open canopy. The canopy is dominated by <i>Pinus echinata</i> codominating with <i>Quercus alba, Quercus rubra</i>, or <i>Quercus velutina</i>, either singly or in combination. <i>Pinus echinata</i> often forms an emergent canopy over the oaks. Other woody species may be present in the shrub and sapling strata. Species from examples in the central Ouachita Mountains include <i>Acer rubrum, Amelanchier arborea, Carya tomentosa, Castanea pumila var. ozarkensis, Cornus florida, Hamamelis virginiana, Nyssa sylvatica, Ostrya virginiana, Prunus serotina, Sassafras albidum, Toxicodendron radicans, Vaccinium arboreum, Vaccinium stamineum</i>, and <i>Vitis rotundifolia</i>. Cover of the herbaceous stratum is variable (20-50%) depending on crown closure and fire history and comprises a mixture of graminoid and forb species. The herbaceous layer is often dominated by <i>Schizachyrium scoparium</i> and <i>Dichanthelium linearifolium</i>, but a diversity of herbaceous species is present. Other herbaceous species can include <i>Antennaria plantaginifolia, Symphyotrichum anomalum, Baptisia bracteata var. leucophaea, Carex</i> sp., <i>Clitoria mariana, Cunila origanoides, Danthonia spicata, Desmodium marilandicum, Desmodium glutinosum, Lespedeza capitata, Lespedeza virginica, Dichanthelium latifolium, Dichanthelium sphaerocarpon var. isophyllum, Solidago caesia, Solidago petiolaris</i>, and <i>Solidago ulmifolia</i>.
