Name: Coleogyne ramosissima Shrubland Alliance
Reference: Western Ecology Working Group of...
Description: This alliance occurs at the transition between the Mojave and Great Basin deserts on mountain slopes, mesas or bajadas bordering intermountain basins. Soils are highly variable across the large range of this vegetation type, but are generally coarse-textured and well-drained. This vegetation is characterized by a sparse to moderately dense shrub layer of Coleogyne ramosissima. Although Coleogyne is apparently restricted to a particular elevational zone, associated shrub species can be of either Mojavean or Great Basin affinities. Shrub species may include Menodora spinescens, Picrothamnus desertorum (= Artemisia spinescens), Eriogonum fasciculatum, Ephedra spp., Atriplex spp., Grayia spinosa, Larrea tridentata, Chrysothamnus viscidiflorus, Yucca baccata, Gutierrezia sarothrae, and Opuntia spp. Occasionally, scattered individuals of Yucca brevifolia may be emergent through the shrub layer. The herbaceous layer is typically sparse. Species of Eriogonum, Navarretia, Sphaeralcea, Pleuraphis jamesii (= Hilaria jamesii), Mirabilis multiflora, Achnatherum hymenoides (= Oryzopsis hymenoides), and Achnatherum speciosum (= Stipa speciosa) may be present. Diagnostic of this alliance is the dominance of Coleogyne ramosissima in the shrub layer.
