Name: Populus tremuloides - Quercus macrocarpa / Andropogon gerardii Woodland Group
Reference: NatureServe Biotics 2019
Description: This aspen-oak woodland group is found primarily on part of the Glacial Lake Agassiz plain in northwestern Minnesota, ranging into south-central Manitoba, Canada. Historically this group occurred in the context of a mosaic of tallgrass prairie, brush prairie and wetlands. It is dominated by <i>Populus tremuloides</i> with scattered <i>Quercus macrocarpa</i> and <i>Betula papyrifera</i>. Shrubs such as willows (<i>Salix</i> spp.) and hazelnuts (<i>Corylus</i> spp.) are also common. The dominant tallgrass species, at least in open, fire maintained sites, is <i>Andropogon gerardii</i> often associated with <i>Sorghastrum nutans, Calamagrostis</i> spp., and <i>Sporobolus heterolepis</i>. Calcareous glacial drift overlain with lacustrine soils ranging from loamy to gravelly is characteristic of the lakeplain within the range of this group. Fire is the most important natural dynamic in this group and helps maintain the open parkland or brush nature of this group. Wind and grazing are also important dynamics. Conversion to agriculture and fire suppression have decreased the range of this group and allowed more shrubs and trees to establish.
