CEGL003938 Juniperus virginiana - Forestiera ligustrina - Rhus aromatica - Hypericum frondosum Shrubland

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Eastern Red-cedar - Upland Swamp-privet - Fragrant Sumac - Cedar Glade St. John''s-wort Shrubland

Colloquial Name: Southern Limestone Glade Margin Shrubland

Hierarchy Level:  Association

Type Concept: This shrubland is a zonal component of Central Basin (Tennessee) limestone cedar glades. It is also found on limestone outcrops of the Alabama Cumberland Plateau and Moulton Valley glade systems, and as a component of cedar glade complexes at Chickamauga-Chattanooga National Military Park. It also occurs on the Pennyroyal Karst Plain of Kentucky. Alabama and Kentucky occurrences are rare and of restricted distribution and limited extent. The substrate consists of broken fragments of flat-bedded sedimentary limestone, with accumulations of shallow soil. 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, Fraxinus americana, and Ulmus alata. Alabama occurrences may contain an occasional Aesculus pavia. A low "herbaceous" stratum is dominated by Cheilanthes lanosa, Pleurochaete luteola, Thuidium delicatulum, Climacium americanum, Cladonia spp., and Opuntia humifusa. Typically grades into open, herbaceous-dominated glades, or into woodlands or forests commonly dominated by Quercus muehlenbergii, Fraxinus americana, and Celtis laevigata.
