Name: Sedum nuttallianum Sparsely Vegetated Alliance Reference: Southeastern Ecology Working Gro... Description: This alliance contains one community characterized by large expanses of exposed granite surfaces, with scattered soil-filled depressions, crevices, gravel areas, and shallow pools. Vegetative cover is sparse and limited to areas where shallow sand or gravel accumulate. Typical species include Sedum nuttallianum, Plantago wrightiana, Talinum parviflorum, Helenium amarum, Campanula reverchonii, Aphanostephus skirrhobasis, Hypericum gentianoides. Areas with deeper soils are dominated by Schizachyrium scoparium occurring with other grasses such as Bouteloua hirsuta, Bouteloua curtipendula, and Aristida purpurea. Bare rock is occupied by scattered patches of crustose and foliose lichens, mosses, and several ferns and fern allies including Selaginella peruviana, Selaginella arenicola ssp. riddellii, Cheilanthes lindheimeri, Cheilanthes tomentosa, Woodsia obtusa ssp. occidentalis, and Pellaea ternifolia. Narrow, shallow crevices harbor species tolerant of the most xeric conditions including Echinocereus reichenbachii, Eriogonum tenellum, and Opuntia leptocaulis.  Accession Code: VB.CC.22783.SEDUMNUTTALLIAN Plot-observations of this Community Concept: 0
