Name: Quercus stellata / Viburnum rufidulum / Schizachyrium scoparium - (Sorghastrum nutans, Helianthus eggertii) Woodland
Reference: NatureServe Biotics 2019
Description: These woodlands are dominated by <i>Quercus stellata</i>; a scattered to dense subcanopy of <i>Juniperus virginiana var. virginiana</i> may be present. This community occurs as open patches (10x30 m or larger) on droughty mid to upper slopes in the unglaciated Interior Low Plateau, including on shaly siltstones of the Fort Payne Formation in the dissected escarpment of the Western Highland Rim of Tennessee, and related sites at Mammoth Cave National Park (Kentucky). The soils in Tennessee examples are mapped as Bodine; this is a droughty, excessively well-drained soil from which calcium ions have been removed by leaching, making it more acidic. The vegetation most frequently occurs on south- to southwest-facing slopes at an elevation of 150-260 m (500-850 feet) msl but may occur on other aspects as well. This community provides habitat for <i>Helianthus eggertii</i>. While fire undoubtedly played a role in its maintenance, local edaphic conditions function to maintain this distinctive vegetation. The presence of a subcanopy of <i>Juniperus virginiana var. virginiana</i> is probably a symptom of fire suppression. Other woody plants observed include <i>Quercus marilandica</i> in the canopy, <i>Cercis canadensis</i> in the subcanopy, and <i>Viburnum rufidulum</i> in the shrub stratum. <i>Schizachyrium scoparium</i> dominates the herbaceous stratum, with <i>Sorghastrum nutans</i> present in some examples. Distinctive herbaceous species present include <i>Eryngium yuccifolium, Ionactis linariifolius, Liatris squarrosa, Polytaenia nuttallii</i>, and <i>Parthenium integrifolium var. integrifolium</i>. The herb layer also contains <i>Dodecatheon meadia, Manfreda virginica, Monarda fistulosa, Symphyotrichum shortii, Ruellia humilis, Helianthus divaricatus</i>, and <i>Trichostema brachiatum</i>.
