Name: Atriplex canescens - Ephedra viridis Talus Shrubland
Reference: Western Ecology Working Group of...
Description: This sparse shrubland association occurs on talus slopes throughout the northern Colorado Plateau. It has been reported from western Colorado and southeastern Utah. Sites are on moderately steep to steep slopes (21-86%), occur between 1500 and 1865 m (4920-6140 feet) elevation, and tend to occur on southeast aspects. The underlying substrate is usually shale, covered by a layer of sandstone talus. Total vegetation cover is somewhat sparse, ranging between 8 and 35%. The shrub layer is generally diverse, while being codominated by <i>Atriplex canescens</i> and <i>Ephedra viridis</i>. Other common shrubs include <i>Ephedra torreyana, Artemisia bigelovii, Chrysothamnus viscidiflorus</i>, and <i>Gutierrezia sarothrae</i>. Total shrub cover ranges from 3 to 30%. The herbaceous layer is similarly diverse, but cover rarely exceeds 5%. The most consistent species are the exotic grass <i>Bromus tectorum</i> and the natives <i>Achnatherum hymenoides, Aristida purpurea</i>, and <i>Hesperostipa comata</i>. Forbs are sparse. Scattered <i>Juniperus osteosperma</i> trees occur throughout many stands, but with cover not exceeding 5%.
