CEGL002285 Ozark Chert Dry Cliff Vegetation
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Ozark Chert Dry Cliff Vegetation
Colloquial Name: Ozark Dry Chert Cliff
Hierarchy Level: Association
Type Concept: This dry chert cliff type is found in the Missouri Ozarks region of the United States. Stands occur on extremely steep to vertical rock exposures along bluffs or rock ledges in valleys. Aspect is variable, but best developed south and west. Soils are generally absent, except on ledges, where they are shallow, very rapidly drained and dry (they can be ephemerally wet). Parent material is chert or cherty conglomerate. Disturbances include drought stress and wind and storm damage. The vegetation contains few, if any, trees, and these are limby, gnarled, open-grown, and stunted. Herbaceous cover is less than 20%, consisting of spring ephemerals and grasses on ledges, and lichens on the open rock. Characteristic woody plants include Quercus marilandica. Herbaceous species include Asplenium bradleyi, Cheilanthes lanosa, Coreopsis lanceolata, Danthonia spicata, Lechea tenuifolia, Opuntia humifusa, and Polygonum tenue. Lichens include Pleopsidium chlorophanum, Cladonia caroliniana, and Xanthoparmelia spp.
