Name: Atriplex confertifolia - (Acamptopappus sphaerocephalus, Picrothamnus desertorum) / (Pleuraphis jamesii) Scrub
Reference: NatureServe Biotics 2019
Description: This sparse warm desert scrub association is known from Glen Canyon National Recreation Area but occurs more widely in the Colorado Plateau. It is characterized by dominance of <i>Acamptopappus sphaerocephalus</i> (with 1-8% cover) and codominance of <i>Atriplex confertifolia</i> and/or <i>Picrothamnus desertorum</i>. Associated shrubs with sparse to low cover may include <i>Chrysothamnus viscidiflorus, Coleogyne ramosissima, Ephedra</i> spp., <i>Lycium andersonii, Gutierrezia</i> spp., <i>Opuntia</i> spp., and <i>Suaeda moquinii</i>. The herbaceous layer has sparse to moderate grass cover that is usually dominated by <i>Pleuraphis jamesii</i>, with up to 10% cover. Other grass species with low cover may include <i>Achnatherum hymenoides, Pleuraphis rigida</i>, and the exotic <i>Bromus rubens</i>. Forb cover is sparse with only exotic <i>Erodium cicutarium</i> with more than trace cover. Stands occur on plains, bajadas, alluvial fans, hills, sideslopes, valley floors, overflow stream channels, and arroyos between 1182 and 1330 m elevation. Sites are flat to moderately sloping and occur on all aspects. Soil surface is mostly bare soil and gravel with low cover of litter. Soils are variable and range from loams to silty clay loams and clays derived from older alluvium or eolian deposits from shale or sandstone.
