Name: Panicum virgatum - Andropogon gerardii Interior Gravel Riverscour Prairie Alliance Reference: NatureServe Biotics 2019 Description: This alliance includes scoured riverbank "prairies" of the Interior regions of the United States, including the Interior Low Plateau, Ozarks, and Ouachitas. These may locally be called "riverside prairies," "linear prairies," "rivershore grasslands," "scoured riverine prairies," or other local names. These grasslands may be associated with dry cobble or gravel riverbanks, as well as flood-scoured, acidic or calcareous bedrock exposures associated with major rivers. This includes riverine gravel/cobble bar "prairies" along the upper Cumberland River in Kentucky and Tennessee, as well as scour areas along high-gradient sections of major rivers, such as the Duck River of Tennessee, the Kentucky and Green rivers of Kentucky, the Glover and Kiamichi rivers of Oklahoma, and the Cossatot River of Arkansas. Examples typically contain <i>Andropogon gerardii, Chasmanthium latifolium, Panicum virgatum, Schizachyrium scoparium</i>, and/or <i>Sorghastrum nutans</i>, any of which could be locally dominant. Examples of this alliance have mixed shrub and herbaceous physiognomy and may include a few taller trees. Trees are characteristically less than 5 m tall (but scattered individuals may approach 10 m), and canopy cover characteristically ranges from 0 to 10% (but in intervals between flood events may locally approach 30%).  Accession Code: urn:lsid:vegbank.org:commConcept:38322-{03D84BEE-9D70-41B3-8011-2EEAF57F1703} Plot-observations of this Community Concept: 0
