Name: Andropogon gerardii - Panicum virgatum - Baptisia australis Herbaceous Vegetation Reference: Eastern Ecology Working Group of... Description: This community is found in the east-central United States along high-gradient sections of major rivers, such as in gorges and along the fall-line. It usually occupies rocky areas within the active channel shelf at an intermediate level above the low-water level and the bank-full level. Flood scouring and ice floods are powerful and ecologically important abrasive forces that shape the physiognomy and composition of this association. Soils are rapidly drained Psamments. Often, soil material is restricted to the narrow interstices of tightly packed boulders, or to small crevices in bedrock exposures. This community is characterized by a luxuriant growth of the robust grasses <i>Andropogon gerardii, Sorghastrum nutans, Panicum virgatum</i>, and <i>Spartina pectinata</i> which resembles prairie vegetation. <i>Tripsacum dactyloides</i> may also occur. Many of the forbs are also typical of prairies. Characteristic species include <i>Baptisia australis, Allium cernuum, Aristida purpurascens, Bidens frondosa, Chasmanthium latifolium, Clematis viorna, Eleocharis compressa, Conoclinium coelestinum (= Eupatorium coelestinum), Eupatorium serotinum, Lespedeza violacea, Packera aurea, Physostegia virginiana, Pycnanthemum virginianum, Solidago rupestris, Teucrium canadense, Veronicastrum virginicum, Zizia trifoliata</i>, and <i>Zizia aurea</i>. Scattered and flood-battered shrubs and tree saplings often occur.  Accession Code: VB.CC.31373.CEGL006283 Plot-observations of this Community Concept: 0
