Name: Eriogonum leptocladon Sparse Vegetation Reference: Western Ecology Working Group of... Description: This sparse shrubland association is characteristic of sheets of loose or partially stabilized sand in southeastern Utah between 1220 and 1573 m (4000-5160 feet) elevation. Stands occur on level to gently sloping sites with a tendency toward warmer western aspects. Soils are loamy sands and sandy loams derived from local eroding sandstone or eolian sands. Most of the unvegetated surface is bare soil, although incipient biological soil crusts (consisting mostly of dark cyanobacteria) may cover up to 20% of the ground in more stable sites. Stands of this association tend to be small and occur in a mosaic of other sandy communities. Total vegetation cover by vascular species rarely exceeds 15%. The open shrub canopy is consistently dominated by <i>Eriogonum leptocladon</i> with between 2 and 10% cover. Other shrubs present may include <i>Eriogonum corymbosum, Atriplex canescens</i>, and <i>Gutierrezia sarothrae</i>. If <i>Artemisia filifolia</i> or <i>Coleogyne ramosissima</i> are present, it is with 1% or less cover. The herbaceous layer is also generally sparse (5% or less total cover) and consists of species adapted to somewhat disturbed, sandy conditions. Common species include <i>Achnatherum hymenoides, Abronia fragrans, Oenothera pallida, Sporobolus</i> spp., and <i>Salsola tragus</i>.  Accession Code: VB.CC.31877.CEGL002822 Plot-observations of this Community Concept: 0
