Name: Quercus alba - Quercus macrocarpa - Carya ovata Forest, Woodland & Savanna Macrogroup Reference: NatureServe Biotics 2019 Description: The vegetation structure of this macrogroup ranges from open savanna or barrens, with at least 10% tree cover, to closed forest. Typical dominant oak species include <i>Quercus alba, Quercus ellipsoidalis, Quercus macrocarpa, Quercus rubra</i>, and/or <i>Quercus velutina</i>. In forest and woodland stands, hickories such as <i>Carya tomentosa, Carya cordiformis, Carya glabra</i>, and <i>Carya ovata</i> are characteristic associates. Forested stands can have a dense shrub understory. Most barrens and savanna examples have understories dominated by prairie graminoids such as <i>Andropogon gerardii, Hesperostipa spartea, Schizachyrium scoparium, Sorghastrum nutans</i>, and <i>Sporobolus heterolepis</i>, and can have a rich forb component. This fire-dependent type is transitional between dry prairies and mesic hardwood forests. This macrogroup is found throughout the glaciated regions of the Midwest, most typically in the tallgrass prairie border-central lowlands region. It can occur on glacial landscape features such as moraines, kettle-kame topography, and outwash plains. Soils are well-drained to excessively drained, with a loamy to sandy texture. Fire suppression leads to more closed-canopy forests and woodlands, and a more mesic understory, and eventually replacement of oak canopy with mesic hardwoods, such as <i>Acer saccharum</i> and <i>Acer rubrum</i>. Periodic strong winds and browsing also impact this type. Many of the stands have been cleared and converted to agriculture.  Accession Code: urn:lsid:vegbank.org:commConcept:40443-{3350F3CA-CDC4-4102-A071-5E341A72EA0F} Plot-observations of this Community Concept: 0
