Name: Sandstone Interior Highlands Talus Sparse Vegetation Reference: Midwestern Ecology Working Group... Description: This sandstone talus community is found in the Ozark and Ouachita regions of the United States. Stands occur at the bases of steep cliffs along larger streams or rivers, or strongly dissected valleys. Aspect is variable, and they can be relatively moist or relatively dry. Soils are generally absent. Parent material is sandstone with a mixture of rock fragments and large boulders. The vegetation is generally sparse but may vary depending on degree of slope, exposure (open versus shaded) and rock type. The composition of the type may be heavily influenced by adjacent forested stands. Vascular plants are generally very sparse, absent, or limited to marginal areas. Vines and viney shrubs are characteristic of this community (at least its margins), because their habit allows them to exploit the combination of abundant available light and scarce rooting opportunities. Characteristic vines and shrubs can include Ribes spp., Toxicodendron radicans, Parthenocissus quinquefolia, and Philadelphus pubescens. Characteristic herbaceous species can include the annual composite Polymnia canadensis and the ferns Dryopteris marginalis and Polypodium virginianum. Sassafras albidum seems to be a particularly characteristic tree species of the margins of this community; Cornus alternifolia is also reported from Missouri occurrences. Foliose, crustose, and umbilicate lichens are common.  Accession Code: VB.CC.27656.SANDSTONEINTERI Plot-observations of this Community Concept: 0
