Name: Andropogon gerardii - Chasmanthium latifolium - Amsonia tabernaemontana var. salicifolia Herbaceous Vegetation Reference: Southeastern Ecology Working Gro... Description: This association occurs along the Duck River in Tennessee's Central Basin, as well as the Green River and Kentucky River in the Interior Low Plateau of Kentucky. The Duck River is undammed and free-flowing for much of its length. Where sections of the river flow west and meet high east-facing banks of Ordovician limestone, the force of seasonally high water levels scours the banks, reducing the likelihood of woody vegetation becoming dominant at these sites. The vegetation is characterized by robust grasses such as <i>Andropogon gerardii, Sorghastrum nutans</i>, and <i>Chasmanthium latifolium</i>. <i>Amsonia tabernaemontana (var. gattingeri, var. salicifolia</i>?) is present as well. This community has been referred to as 'scoured riverine bluff prairie.' This or closely related vegetation is found in Kentucky along the Kentucky River and Green River. On limestone bedrock shelves along their banks, the vegetation includes the grasses <i>Andropogon gerardii, Chasmanthium latifolium, Elymus virginicus var. virginicus (= Elymus virginicus var. intermedius), Elymus riparius</i>?, and <i>Panicum virgatum</i> (which is rare in most Kentucky uplands). Shrubs and woody vines include <i>Cornus obliqua, Hypericum prolificum</i>, and <i>Toxicodendron radicans</i>. Additional herbs are infrequent but include <i>Solidago rupestris</i>.  Accession Code: VB.CC.36170.CEGL004739 Plot-observations of this Community Concept: 0
