Name:
Juniperus virginiana - Rhus aromatica Alkaline Bedrock Shrubland Alliance
Reference:
NatureServe Biotics 2019
Description:
These are shrubland zones of calcareous glades and rocky cliffs. Characteristic shrubs include <i>Berchemia scandens, Forestiera ligustrina, Frangula caroliniana, Hypericum frondosum, Juniperus virginiana var. virginiana, Rhus aromatica var. aromatica, Sideroxylon lycioides</i>, and stunted individuals of <i>Acer saccharum, Fraxinus americana, Quercus austrina</i> (in Bibb County, Alabama, examples), <i>Quercus muehlenbergii, Quercus shumardii</i> (in Tennessee examples), and <i>Ulmus alata</i>. Typically grades into open, herbaceous-dominated glades or into woodlands or forests commonly dominated by <i>Celtis laevigata, Fraxinus americana, Fraxinus quadrangulata, Quercus muehlenbergii</i>, and/or <i>Quercus stellata</i>. This alliance is a zonal component of calcareous glades; it occupies deeper soil zones around herbaceous-dominated flatrock glades. 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, and the Moulton Valley glade systems of northern Alabama.
