Name: Pinus banksiana - (Quercus ellipsoidalis) / Schizachyrium scoparium - Prairie Forbs Barrens Woodland
Reference: Midwestern Ecology Working Group...
Description: This jack pine barrens type is found in the northern tallgrass and prairie-forest border region of the United States and Canada. The topography is flat to rolling, and stands are formed on sands of glacial, lacustrine, or riverine origin. The sandy soils are acidic, droughty, and infertile. The open vegetation was historically influenced by fires. The vegetation is dominated by grasses and forbs with a sparse tree layer. The dominant tree is <i>Pinus banksiana</i>, with varying amounts of <i>Quercus ellipsoidalis, Pinus resinosa, Populus tremuloides</i>, and <i>Populus grandidentata</i>. The composition of all the strata of this community can vary significantly. <i>Pinus banksiana</i> is a constant across all sites, but it can be virtually the only tree species present or one of many. <i>Quercus ellipsoidalis</i> or <i>Quercus macrocarpa</i> can outnumber <i>Pinus banksiana</i> on some sites, especially those that have not been burned for many years. <i>Pinus resinosa</i> is typically at low densities in most examples of this community. Dry sites tend to have fewer woody shrub species and more herbaceous species with sand prairie affinities. Among these are <i>Dalea villosa, Koeleria macrantha, Prunus pumila, Schizachyrium scoparium</i>, and <i>Calamovilfa longifolia</i>. Dry-mesic areas have more <i>Andropogon gerardii, Amorpha canescens, Liatris aspera</i>, and <i>Hesperostipa spartea (= Stipa spartea)</i>. Patches of heath may occur, dominated by shrubby species such as <i>Arctostaphylos uva-ursi, Comptonia peregrina, Hudsonia tomentosa</i>, and <i>Vaccinium angustifolium</i>.
