Name:
Quercus phellos Piedmont-Cumberland Wet Depression Forest Alliance
Reference:
NatureServe Biotics 2019
Description:
This alliance includes vegetation of wet depressions and related habitats in the Piedmont, Cumberland, and Interior Plateau regions of the southeastern United States from Alabama north to Kentucky and Maryland. Examples have <i>Quercus phellos</i> as an indicator and typically dominant to codominant component of the canopy. It is noteworthy as an indicator in these regions as it is primarily a species of the coastal plains. The associated species vary across this range. Additional canopy trees include <i>Liquidambar styraciflua, Quercus alba, Quercus lyrata, Quercus michauxii, Quercus nigra, Quercus shumardii</i>, and <i>Quercus stellata</i>. Some other canopy and subcanopy trees include <i>Acer floridanum, Carya carolinae-septentrionalis, Celtis laevigata, Fraxinus americana, Juglans nigra, Morus rubra, Nyssa biflora</i>, and <i>Ulmus americana</i>. The small understory trees <i>Cercis canadensis, Cornus florida, Cornus foemina, Crataegus viridis, Quercus oglethorpensis</i>, and <i>Sideroxylon lycioides</i> may also occur. Some herbs that are found in component associations include <i>Carex albolutescens, Carex intumescens, Carex joorii, Chasmanthium laxum, Chasmanthium sessiliflorum, Dichanthelium boscii, Dulichium arundinaceum, Glyceria striata, Hymenocallis occidentalis, Podophyllum peltatum</i>, and <i>Zephyranthes atamasca</i>. This alliance occurs in upland depressions and swales in flatwoods that do not receive overbank flooding, including gently sloped upper drainages in flat Piedmont terrain with dense clay hardpan soils that have restricted internal drainage; shallow depressions in ridgetop or plateau-top sandstone of the Cumberland Plateau or on limestones and dolostones in the Southern Ridge and Valley; sloping terrain or shallowly depressed upland flats over gabbro-derived clays in the Piedmont of Georgia and South Carolina; as well as depression swamps found in the Piedmont and in limited areas of the adjacent Inner Coastal Plain.
