Name: Quercus macrocarpa - Quercus (alba, ellipsoidalis, velutina) Woodland Alliance Reference: Midwestern Ecology Working Group... Description: This alliance, found in the Midwest, occurs on wet-mesic to dry-mesic sites. Stands in this alliance can have a canopy ranging from moderately open to moderately closed, approximately 25-80%. There is often a moderate shrub canopy (30-50%) layer 1-2 m tall but this can be absent. Quercus macrocarpa is the dominant tree in nearly all stands in this alliance. It can also be prominent in the shrub layer. Celtis occidentalis and Quercus bicolor are common trees in wet-mesic stands, along with smaller amounts of Platanus occidentalis and Ulmus americana, while Quercus alba, Quercus muehlenbergii, Quercus rubra, and Quercus velutina are often found in mesic to dry-mesic stands. In the shrub layer, Corylus americana is the most abundant. It is often accompanied by Ceanothus herbaceus, Cornus foemina, Euonymus atropurpurea, and Prunus spp. The herbaceous layer contains species such as Andropogon gerardii, Carex pensylvanica, Elymus virginicus, Laportea canadensis, and Sorghastrum nutans. This alliance occurs in wet-mesic, mesic, and dry-mesic moisture regimes. The environmental conditions vary substantially with the moisture regime. Wet-mesic communities are typically found on terraces near rivers and streams. Mesic and dry communities are found on flat, rolling, or hilly topography. All communities are most often found on silt and loam soils, and upland communities are also found on coarse-grained soils. Fire is an important factor in maintaining the relatively open structure of upland stands in this alliance.  Accession Code: VB.CC.18661.QUERCUSMACROCAR Plot-observations of this Community Concept: 0
