Name: Fraxinus anomala - Rhus trilobata Talus Shrubland
Reference: Western Ecology Working Group of...
Description: This shrubland association occurs on steep, rocky colluvial slopes as well as on thin soils near the edges of canyon and mesa rims. Sites are located on gentle to steep (1- to 34-degree) slopes between 1195 and 1536 m elevation, with a strong orientation toward northerly aspects. The unvegetated surface is mostly covered by rocks, gravel, boulders, bedrock and bare soil, with little litter or dead wood evident. Soils tend to be sandy, with a few stands on silt loams or clay loams derived from sandstone and shale. This open shrubland is characterized by sparse to low cover (<15% total cover) from a mix of xeric shrubs, among which <i>Fraxinus anomala</i> and <i>Rhus trilobata</i> are conspicuous and usually at least codominant. Many other shrub species are usually present, including <i>Artemisia bigelovii, Atriplex confertifolia, Ephedra torreyana, Chrysothamnus viscidiflorus var. stenophyllus</i>, and <i>Gutierrezia sarothrae</i>. The herbaceous layer may include many species but never provides more than a few percent cover; <i>Pleuraphis jamesii, Achnatherum hymenoides, Stanleya pinnata, Chamaesyce fendleri</i>, and <i>Xylorhiza</i> spp. are the most consistent species. Biological soil crust formation is rare on these active slopes.
