Name: Schizachyrium scoparium - Sorghastrum nutans - Silphium spp. Herbaceous Vegetation Reference: Southeastern Ecology Working Gro... Description: Mesic to dry-mesic perennial grasslands of the southern Ridge and Valley of Tennessee. This vegetation is dominated by Schizachyrium scoparium and Sorghastrum nutans, in patches of various combinations and percent covers depending on slope position. Also contains Andropogon spp., Dichanthelium spp., and diverse forbs. Best developed on mid to lower slopes, where soils are deep enough to support perennial grasses. Silphium terebinthinaceum can be a prominent feature of this vegetation type. Some other taxa present include Hypericum dolabriforme, Manfreda virginica, Silphium asteriscus, and Silphium trifoliatum. Some examples of this vegetation are partly maintained by mechanical clearing of powerline rights-of-way. A slightly more mesic community which may occur adjacent to this one is Andropogon gerardii - Panicum (anceps, virgatum) Herbaceous Vegetation (CEGL007931). Under conditions of fire suppression, Juniperus virginiana may invade examples of this vegetation and can form dense stands which suppress herbaceous plants.  Accession Code: VB.CC.19570.SCHIZACHYRIUMSC Plot-observations of this Community Concept: 0
