Name: Gutierrezia (microcephala, sarothrae) Dwarf-shrubland
Reference: NatureServe Biotics 2019
Description: This dwarf-shrubland association is known from Glen Canyon National Recreation Area and Grand Canyon National Park and is likely widespread throughout the interior western U.S. The sparse to open dwarf-shrub canopy is characterized and dominated by <i>Gutierrezia sarothrae</i> and/or <i>Gutierrezia microcephala</i>. Total shrub cover is variable, ranging from 15-20% for open stands with 8-18% cover of <i>Gutierrezia</i> spp. to sparse stands with 3-10% shrub cover (<i>Gutierrezia sarothrae</i> with 1-7% cover and/or <i>Gutierrezia microcephala</i> with 3-5%). Trees are generally lacking although occasional <i>Tamarix chinensis</i> or <i>Juniperus osteosperma</i> may be present with trace cover. Other shrubs present with sparse to low cover may include scattered <i>Acacia greggii, Artemisia filifolia, Atriplex confertifolia, Chrysothamnus viscidiflorus, Coleogyne ramosissima, Ephedra aspera, Ericameria nauseosa, Lycium andersonii, Opuntia phaeacantha, Opuntia polyacantha</i>, or <i>Yucca baccata</i>. If present the herbaceous layer is generally sparse and composed of weedy, often exotic annual and short-lived perennial species. Stands occur on plateaus, benches, hills, slopes, valley bottoms, and along washes/drainage channels. Sites are flat to gently sloping and between 1100 and 1900 m elevation. Soils are variable, ranging from sands to silty clay loams derived from eolian or alluvial deposits, shales or sandstone.
