Name: Panicum virgatum - Andropogon gerardii Grand Prairie Herbaceous Vegetation
Reference: Southeastern Ecology Working Gro...
Description: This mesic tallgrass prairie community occurs on Pleistocene alluvial terraces in eastern Arkansas and northeastern Louisiana. It is characterized by varying dominance of Panicum virgatum, Andropogon gerardii, Sorghastrum nutans, and Schizachyrium scoparium. Typical forbs include Liatris pycnostachya, Liatris elegans, Baptisia alba var. macrophylla, Baptisia bracteata var. leucophaea, Silphium laciniatum. Mespilus canescens is endemic to the Grand Prairie; and Oenothera pilosella ssp. sessilis may be endemic. Soils have relatively thin topsoil of silt (loess) underlain by impermeable subsoil. Prairie sites are flat interfluves subject to extremes of wet/dry, and have few breaks to retard fire. In a region with >125 cm annual rainfall, frequent fire is essential for maintenance.
