Name: Schizachyrium scoparium - Andropogon ternarius - Liatris microcephala - (Pityopsis ruthii) Herbaceous Vegetation
Reference: Southeastern Ecology Working Gro...
Description: This is a river scour community of the Hiwassee and Ocoee rivers of southeastern Tennessee. In this temporarily flooded river scour community, the herbaceous species are limited to the cracks and crevices of the boulders, with Pityopsis ruthii dominating in many places. In its more open phase, it is dominated by perennial grasses and forbs. The principal grasses here are Schizachyrium scoparium, Andropogon ternarius (both becoming abundant in areas with increased soils), and Panicum sp. Other abundant herbaceous species include Liatris microcephala, Symphyotrichum novae-angliae (= Aster novae-angliae), Solidago sp., Coreopsis tripteris, and Agalinis sp. The shrub stratum is also clumpy in distribution with Cornus amomum, Hypericum prolificum, and Leucothoe racemosa also present. Several liana species are present, most notably Bignonia capreolata and Toxicodendron radicans, along with the non-native Lonicera japonica. The adjacent blufftop is dominated by Pityopsis ruthii and lichens, with small clusters of Pinus virginiana and Juniperus virginiana scattered throughout, where soils have accumulated covering between 25% and 40% of the more open areas. The woody plants become thicker about 25 m from the edge, with coverage approaching 75-90% where lack of scour has allowed woody species to invade. Other canopy species noted include Pinus strobus, Platanus occidentalis, and Acer rubrum. In the more open areas, these species are small and stunted.
