Name: Schizachyrium scoparium - Sporobolus compositus - Fimbristylis puberula var. puberula Wooded Herbaceous Vegetation Reference: Southeastern Ecology Working Gro... Description: This dry blackland prairie community of the Upper West Gulf Coastal Plain of Arkansas typically occurs on dry ridges. Examples also occur on recovering eroded areas. The vegetation is typically short (2-3 feet) and somewhat sparse, with patches of bare ground present. Dominant species include Schizachyrium scoparium, Sporobolus compositus (= Sporobolus asper), and Fimbristylis puberula var. puberula. Other herbaceous species include Acacia angustissima, Agalinis skinneriana, Andropogon virginicus, Asclepias viridiflora, Asclepias viridis, Manfreda virginica (rarely), Coreopsis lanceolata, Croton capitatus, Croton monanthogynus, Dalea purpurea, Delphinium carolinianum ssp. virescens, Hedyotis nigricans var. nigricans, Liatris squarrosa, Rudbeckia hirta (in places large clones covering 2-3 square m perhaps the result of heavy grazing in the past), and Ruellia humilis. The bare soil is often covered with blue-green algae (Nostoc sp.). Occasional woody species include Sideroxylon lanuginosum (= Bumelia lanuginosa), Diospyros virginiana, Fraxinus americana, Quercus muehlenbergii, and Juniperus virginiana var. virginiana which occur locally during periods of fire suppression or between severe droughts. Fire and edaphic factors (drought) play a role in limiting woody vegetation distribution in this community. Soils are calcareous alkaline clays with the high shrink-swell character of the Sumter and Demopolis series over deep calcareous substrates comprising marl, chalk, or broken limestone.  Accession Code: VB.CC.26474.SCHIZACHYRIUMSC Plot-observations of this Community Concept: 0
