Name: Gutierrezia (microcephala, sarothrae) - (Encelia frutescens, Brickellia microphylla) / Stephanomeria pauciflora Dwarf-shrubland
Reference: NatureServe Biotics 2019
Description: This sparse slickrock dwarf-shrubland association is known from Glen Canyon National Recreation Area and is likely more widespread in the Colorado Plateau. It is characterized by a sparse dwarf-shrub canopy dominated by <i>Gutierrezia microcephala</i> or <i>Gutierrezia sarothrae</i> with the perennial forb <i>Stephanomeria pauciflora</i> dominating the herbaceous layer with up to 3% cover. Sometimes <i>Encelia frutescens</i> and/or <i>Brickellia microphylla</i> are codominant in the shrub canopy layer with less than 2% individual cover. Several other associated shrubs may be present with sparse to low cover. The sparse herbaceous cover may include native, perennial grasses <i>Achnatherum hymenoides, Aristida purpurea, Pleuraphis jamesii</i>, and <i>Sporobolus cryptandrus</i>, and the exotic annual grasses <i>Bromus rubens, Bromus tectorum</i>, and <i>Schismus barbatus</i>. This sparse dwarf-shrubland has total vegetation cover of 1 to 11%. Stands occur on slickrock benches, lakeshores, piedmont slopes, sideslopes, canyon sides, and mesas between 1101 and 1213 m elevation, all in close proximity to the lakeshore. Sites range from flat to moderately sloping, occurring on all aspects. Bedrock covers most of the unvegetated surface, with lesser cover by bare soil, sand, gravel, and large rocks. Soils are sands, loamy sands, and silt loams derived from eolian or alluvial deposits, from sandstones or shales.
