Description:
This association represents Ridge and Valley woodlands found on the 'Red Knobs' landform in the vicinity of Little Toqua Creek in the Cherokee National Forest. These knobs are composed of red calcareous sandstone. The reddish soils are of the Tellico Soil Series, which consists of well-drained soils on high hills and knobs, formed in residuum from reddish, calcareous sandstone, which contains seams of sandy shale. These knobs are from 275-300 m (900-1000 feet) high and are capped by a series of openings with xeric vegetation dominated by Quercus stellata and Pinus virginiana. Canopy closure is variable; the knobs with lower canopy closure exhibit an herbaceous stratum dominated by Schizachyrium scoparium and/or Piptochaetium avenaceum (= Stipa avenacea). These open woodlands have a grass- and forb-dominated understory, exhibiting a barrens-like appearance. The most notable and characteristic species in this stratum are Andropogon gerardii, Lithospermum canescens and Manfreda virginica. Other herbaceous species include Agrimonia sp., Antennaria sp., Arabis laevigata, Minuartia patula? (= Arenaria patula?), Asclepias tuberosa, Asclepias viridiflora, Asteraceae spp., Bidens sp., Desmodium rotundifolium, Desmodium sp., Dichanthelium boscii, Eupatorium fistulosum, Euphorbia corollata, Geranium carolinianum, Helianthus hirsutus, Helianthus sp., Hypericum hypericoides ssp. multicaule (= Hypericum stragulum), Hypoxis hirsuta, Lespedeza sp., Parthenium integrifolium, Penstemon canescens, Phlox amoena, Pycnanthemum tenuifolium, Sanicula sp., Packera anonyma (= Senecio anonymus), Sphenopholis nitida?, Tephrosia virginiana, and Verbena simplex.
