Name: Cercocarpus intricatus Slickrock Sparse Vegetation Reference: NatureServe Biotics 2019 Description: This sparse shrubland association occurs on exposed sandstone slickrock in the Colorado Plateau. Total vegetation cover is less than 15% and often less than 5%. <i>Cercocarpus intricatus</i> is dominant or codominant, with lesser cover by other shrubs such as <i>Amelanchier utahensis, Arctostaphylos patula, Artemisia bigelovii, Cercocarpus montanus, Glossopetalon spinescens var. meionandrum, Ephedra viridis</i>, or <i>Fraxinus anomala</i>. The herbaceous layer is diverse, variable and low in cover. Occasional dwarfed individuals (often only 1-1.5 m tall) of <i>Pinus edulis</i> or <i>Juniperus osteosperma</i> may occur with low cover. The herbaceous cover is sparse and frequently includes <i>Achnatherum hymenoides, Bouteloua gracilis</i>, and <i>Pleuraphis jamesii</i>. Forbs are variable among plots and only have trace cover. Stands are restricted to exposures of massive sandstones such as on the Colorado Plateau. Elevations range between 1196 and 2348 m (3920-7700 feet), while slopes and aspects vary widely. The density of the vegetation is limited by the availability of crevices and shallow depressions where sandy soil collects and plants can root. Soils are rapidly drained loamy sands derived from Navajo sandstone, White Rim sandstone of the Cutler Group, or Cedar Mesa sandstone. Most of the surface is sandstone, sometimes with high cover of lichens. Litter and biological soil crusts have sparse to low cover.  Accession Code: urn:lsid:vegbank.org:commConcept:31879-{FD476EC8-F8C6-4F54-AA24-9D14CBA7DC1F} Plot-observations of this Community Concept: 7
