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 <i>Schizachyrium scoparium</i> and <i>Sorghastrum nutans</i>, in patches of various combinations and percent covers depending on slope position. Also contains <i>Andropogon</i> spp., <i>Dichanthelium</i> spp., and diverse forbs. Best developed on mid to lower slopes, where soils are deep enough to support perennial grasses. <i>Silphium terebinthinaceum</i> can be a prominent feature of this vegetation type. Some other taxa present include <i>Hypericum dolabriforme, Manfreda virginica, Silphium asteriscus</i>, and <i>Silphium trifoliatum</i>. 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 ~<i>Andropogon gerardii - Panicum (anceps, virgatum)</i> Herbaceous Vegetation (CEGL007931)$$. Under conditions of fire suppression, <i>Juniperus virginiana</i> may invade examples of this vegetation and can form dense stands which suppress herbaceous plants.
