Name: Central Interior-Appalachian Riverscour Barrens & Prairie Group
Reference: NatureServe Biotics 2019
Description: This group consists of riverbank "prairies" and riverine shrublands often occurring as distinct zones, maintained by flash flooding events on larger rivers of the south-central portion of the United States, including the Central and Southern Appalachians, Interior Low Plateau, Ozark and Ouachita regions. Stands are scoured by floods that may reach well above normal summer water levels. Grasses typical of midwestern prairies are characteristic of this group, including <i>Andropogon gerardii, Panicum virgatum, Schizachyrium scoparium</i>, and/or <i>Sorghastrum nutans</i>. Typical shrubs may include <i>Alnus serrulata, Cephalanthus occidentalis, Hamamelis virginiana, Ilex vomitoria</i>, and <i>Physocarpus opulifolius</i>. The substrate includes gravelly streambanks, cobbles, as well as exposed bedrock that ranges from acidic to calcareous. The vegetation is highly variable in composition and structure, with plants often restricted to boulder cracks and shallow soil pockets.
