Name:
Juniperus virginiana - Rhus aromatica Shrubland Alliance
Reference:
Southeastern Ecology Working Gro...
Description:
This alliance, encompassing shrubland zones of calcareous glades and rocky cliffs, is a zonal component of these systems; it occupies deeper soil zones around herbaceous-dominated flatrock glades or exposed areas at the tops of cliffs. It may occur as islands in herbaceous-dominated areas or as a marginal zone varying from 5-30 m in width. Examples are known from the limestone glades of the Central Basin of Tennessee, limestone outcrops of the Alabama Cumberland Plateau, dolostone glades associated with the Cahaba River in Bibb County, Alabama, the Moulton Valley glade systems of northern Alabama, or rocky limestone cliffs in central Kentucky. Characteristic shrubs include Juniperus virginiana var. virginiana, Rhus aromatica var. aromatica, Frangula caroliniana, Forestiera ligustrina, Berchemia scandens, Hypericum frondosum, Sideroxylon lycioides, and stunted individuals of Acer saccharum, Quercus muehlenbergii, Quercus shumardii (in Tennessee examples), Quercus austrina (in Bibb County, Alabama, examples), Fraxinus americana, and Ulmus alata. Typically grades into open, herbaceous-dominated glades or into woodlands or forests commonly dominated by Quercus muehlenbergii, Quercus stellata, Fraxinus americana, Fraxinus quadrangulata, and/or Celtis laevigata.
