Name: Achnatherum hymenoides Shrub Grassland Reference: NatureServe Biotics 2019 Description: Stands occur in the southern Colorado Plateau on low to moderately steep slopes at elevations from 1485-2131 m (4869-6991 feet). Landforms are variable and range from hills, mesas, sideslopes, bajadas to stands along drainage channels and in sand deposits. Substrates are typically sandy soils, but textures range from sandy loam to clay loam. There may be low cover of gravel. The vegetation is characterized by a lush perennial herbaceous layer dominated by <i>Achnatherum hymenoides</i> with an open shrub layer. The total shrub cover ranges from 5-20%. The total herbaceous cover ranges from 50-75%. The shrub stratum is typically composed of a mixture of shrub species, although one may dominate. Common shrubs include scattered <i>Atriplex canescens, Ephedra torreyana, Ericameria nauseosa, Eriogonum leptophyllum, Gutierrezia sarothrae, Parryella filifolia, Purshia tridentata, Tetradymia canescens</i>, or <i>Yucca angustissima</i>. The average height for the shrub stratum is 1-2 m. The herbaceous stratum is dominated by the native grass <i>Achnatherum hymenoides</i>; other herbaceous species present may include <i>Pleuraphis jamesii, Poa fendleriana</i>, or <i>Sporobolus airoides</i>. The non-native invasive species <i>Bromus tectorum</i> and <i>Carduus nutans</i> both occur with significant cover.  Accession Code: urn:lsid:vegbank.org:commConcept:32183-{094401A6-6BFC-4539-8E6B-415A36A446C6} Plot-observations of this Community Concept: 0
