Name: Panicum virgatum - Andropogon gerardii Grand Prairie Grassland
Reference: NatureServe Biotics 2019
Description: This mesic tallgrass prairie community occurs on Pleistocene alluvial terraces in eastern Arkansas and northeastern Louisiana. It is characterized by varying dominance of <i>Panicum virgatum, Andropogon gerardii, Sorghastrum nutans</i>, and <i>Schizachyrium scoparium</i>. Typical forbs include <i>Liatris pycnostachya, Liatris elegans, Baptisia alba var. macrophylla, Baptisia bracteata var. leucophaea, Silphium laciniatum</i>. <i>Mespilus canescens</i> is endemic to the Grand Prairie; and <i>Oenothera pilosella ssp. sessilis</i> 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 &gt;125 cm annual rainfall, frequent fire is essential for maintenance.
