Name: Igneous Ozark Dry Cliff Sparse Vegetation
Reference: Midwestern Ecology Working Group...
Description: This igneous dry cliff type is found in the Missouri Ozarks of the United States. Stands occur on extremely steep to vertical rock exposures along bluffs and mountain domes, often occurring in a series of irregular rock terraces and ledges or as highly weathered massive outcrops. Aspect is variable, but sites are best developed south and west. Soils are generally absent, except on ledges, where they are shallow, ephemerally wet, but very rapidly drained. Parent material is igneous (dellenite, felsite, granite or rhyolite). The vegetation contains few, if any, tree species, but if present they are stunted, limby, and gnarled. Herbaceous cover is sparse (less than 20%) consisting of spring ephemerals and grasses on ledges. Lichens are common on the rock face. Sites are disturbed by droughts, wind and storm damage. Woody plants include <i>Juniperus virginiana</i> and <i>Ulmus alata</i>. Characteristic herbaceous species include <i>Symphyotrichum oblongifolium (= Aster oblongifolius), Cheilanthes lanosa, Coreopsis lanceolata, Danthonia spicata, Opuntia humifusa (= Opuntia compressa), Polypodium virginianum (= Polypodium vulgare var. virginianum)</i>, and <i>Sporobolus clandestinus</i>. Lichens include <i>Pleopsidium chlorophanum (= Acarospora chlorophana), Cladonia caroliniana, Cladonia strepsilis, Placidium lachneum (= Dermatocarpon lachneum)</i> and <i>Punctelia hypoleucites (= Parmelia hypoleucites)</i>.
