Name:
Quercus marilandica / Schizachyrium scoparium - (Helianthus mollis, Silphium asteriscus, Liatris aspera) Woodland
Reference:
Southeastern Ecology Working Gro...
Description:
These barrens are found on flat exposed ridgetops of the Western Highland Rim (Lewis County, Tennessee), and are dominated by a great variety of grasses and forbs. Scattered <i>Quercus marilandica</i> are characteristic. Among the dominant grasses, <i>Schizachyrium scoparium</i> is most abundant, with <i>Andropogon gerardii</i> and <i>Sorghastrum nutans</i>; <i>Carex complanata</i> and <i>Dichanthelium</i> spp. are also present. Forbs present include <i>Liatris aspera, Liatris spicata, Silphium asteriscus, Monarda fistulosa, Mimosa microphylla, Tephrosia virginiana, Lobelia puberula, Eryngium yuccifolium, Euphorbia corollata, Porteranthus stipulatus, Symphyotrichum patens (= Aster patens), Sericocarpus linifolius (= Aster solidagineus), Eupatorium hyssopifolium, Eupatorium rotundifolium, Eupatorium serotinum, Eupatorium sessilifolium, Parthenium integrifolium, Solidago odora, Helianthus hirsutus, Hypericum virgatum (= Hypericum denticulatum var. acutifolium)</i>, and <i>Lysimachia tonsa</i>. In addition, this community provides habitat for <i>Helianthus eggertii</i>, a globally rare plant. At the one site known, this vegetation consists of scattered <i>Quercus marilandica</i> with a dense cover of grasses and forbs. Due to fire suppression, <i>Rhus copallinum</i> is invading; adjoining areas have been converted to <i>Festuca</i> pasture or are in <i>Quercus stellata - Quercus falcata</i> forest. These barrens occur on winter-wet, summer-dry loessal soils on the surface of the Western Highland Rim of middle Tennessee. Soils are generally deep, with chert fragments; rock outcrops are absent. The presence of this or similar vegetation may be related to remnant deposits of Cretaceous gravels which remain on some of the high flat ridges in this landscape.
