Name:
Schizachyrium scoparium - Sorghastrum nutans Coastal Plain Prairie Alliance
Reference:
NatureServe Biotics 2019
Description:
This alliance includes a variety of relatively restricted dry-mesic patch prairie types which are found in the coastal plains of the southeastern United States. They are rare and/or have been greatly reduced through land-use change. The most abundant species in stands of this alliance are <i>Bouteloua curtipendula, Schizachyrium scoparium</i>, and <i>Sorghastrum nutans</i>. Other common or characteristic graminoid species include <i>Andropogon gerardii, Andropogon glomeratus, Carex</i> spp., <i>Danthonia spicata, Fimbristylis puberula, Panicum flexile, Panicum virgatum, Sorghastrum nutans</i>, and <i>Sporobolus clandestinus</i>. Component forbs are highly variable among the various associations across the region, with members of the Asteraceae and Fabaceae being most abundant and prominent. Some examples may exhibit a scattered canopy of one or more of <i>Juniperus virginiana var. virginiana, Quercus muehlenbergii</i>, and/or <i>Quercus stellata</i>. Much of this patch prairie vegetation occurs on distinctive soils or geologic formations, such as calcareous clays. This includes the Jackson Formation of Mississippi and Louisiana; the Cook Mountain Formation, Fleming Formation, and Morse Clays of Louisiana; and the Demopolis and related formations of the Alabama Black Belt.
