Name: Quercus stellata / Viburnum rufidulum / Schizachyrium scoparium - (Sorghastrum nutans, Helianthus eggertii) Woodland Reference: Southeastern Ecology Working Gro... Description: These woodlands are dominated by Quercus stellata; a scattered to dense subcanopy of Juniperus virginiana var. virginiana may be present. This community occurs as open patches (10 x 30 m or larger) on mid to upper slopes of shaley siltstones of the Fort Payne Formation in the dissected escarpment of the Western Highland Rim of Tennessee. The soils 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 500-850 feet msl but may occur on other aspects as well. This community provides habitat for Helianthus eggertii. While fire undoubtedly played a role in its maintenance, local edaphic conditions function to maintain this distinctive vegetation. The presence of a subcanopy of Juniperus virginiana var. virginiana is probably a symptom of fire suppression. Other woody plants observed include Quercus marilandica in the canopy, Cercis canadensis in the subcanopy, and Viburnum rufidulum in the shrub stratum. Schizachyrium scoparium dominates the herbaceous stratum, with Sorghastrum nutans present in some examples. Distinctive herbaceous species present include Eryngium yuccifolium, Ionactis linariifolius, Liatris squarrosa, Polytaenia nuttallii, and Parthenium integrifolium var. integrifolium. The herb layer also contains Dodecatheon meadia, Manfreda virginica, Monarda fistulosa, Symphyotrichum shortii (= Aster shortii), Ruellia humilis, Helianthus divaricatus, and Isanthus brachiatus.  Accession Code: VB.CC.25670.QUERCUSSTELLATA Plot-observations of this Community Concept: 0
