Name: Atriplex canescens - (Ephedra viridis) / (Muhlenbergia porteri) Sandstone Sparse Vegetation
Reference: NatureServe Biotics 2019
Description: This sparse association is currently only known from Wupatki National Monument in Arizona, and the following description is based on occurrences there. Additional information will be added as it becomes available. Elevation ranges from 1340-1480 m (4396-4856 feet). The topography ranges from small to steep slopes with 0-25% slope. This association is specific to sandstone soils including bluffs, boulders, and shards. Total vegetation cover is 5-16%, and total species diversity ranges from 12-17 species in the 7 sampled plots. The shrub layer is dominated by <i>Atriplex canescens</i> and sometimes <i>Ephedra viridis</i>. The herbaceous layer can be dominated by <i>Muhlenbergia porteri</i>. <i>Atriplex canescens</i> must be present in this association, even with low percent cover. <i>Ephedra viridis</i> and <i>Muhlenbergia porteri</i> are often present; however, they do not necessarily need to be present within this sparse vegetation type.
