Name: Populus tremuloides - Quercus macrocarpa - Salix spp. / Andropogon gerardii Shrubland Reference: Midwestern Ecology Working Group... Description: This aspen - oak brush prairie shrubland is found in the aspen parkland regions of the United States and Canada, specifically northwestern Minnesota and southeastern Manitoba. Stands occur on somewhat poorly drained to well-drained, sandy clay loam to loamy fine sandy soils. A sand and gravel subtype occurs on coarse-textured outwash deposits. These soils form in lake-washed glacial till or in sandy lacustrine deposits (of variable thickness) over till. Entisols are common; most soils are strongly calcareous. The vegetation is composed of various amounts of shrubs in a matrix of herbaceous prairie species. Andropogon gerardii and Sporobolus heterolepis are common throughout this community. On drier sites Schizachyrium scoparium and Koeleria macrantha are also important, while on wetter sites Spartina pectinata, Calamagrostis stricta ssp. inexpansa (= Calamagrostis inexpansa), and Muhlenbergia richardsonis are codominants. The major shrub species are Populus tremuloides, Salix spp. (including Salix humilis), and Quercus macrocarpa. Amelanchier alnifolia, Amorpha canescens, Prunus pumila and Corylus spp. are usually present. The brush layer is generally less than 2 m tall with a total cover of 30-50%. The dominant grasses of most sites are tall or mid grasses. Fires are important to prevent conversion of this community to more wooded types.  Accession Code: VB.CC.19706.POPULUSTREMULOI Plot-observations of this Community Concept: 0
