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 Quercus marilandica are characteristic. Among the dominant grasses, Schizachyrium scoparium is most abundant, with Andropogon gerardii and Sorghastrum nutans; Carex complanata and Dichanthelium spp. are also present. Forbs present include 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), and Lysimachia tonsa. In addition, this community provides habitat for the Federal Threatened Helianthus eggertii. At the one site known, this vegetation consists of scattered Quercus marilandica with a dense cover of grasses and forbs. Due to fire suppression, Rhus copallinum is invading; adjoining areas have been converted to Festuca pasture or are in Quercus stellata - Quercus falcata 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.
