Name: Sporobolus cryptandrus Great Basin Grassland Reference: NatureServe Biotics 2019 Description: The association is found on terraces of large rivers in the Colorado Plateau and Uinta Basin and likely occurs elsewhere in the southwestern U.S. The vegetation is dominated by the warm-season perennial graminoid <i>Sporobolus cryptandrus</i>. Other graminoids such as <i>Achnatherum hymenoides, Equisetum variegatum, Hesperostipa comata, Pleuraphis jamesii, Sporobolus contractus</i>, or <i>Sporobolus giganteus</i> frequently occur in low abundance. Low cover of native forbs such as <i>Sphaeralcea grossulariifolia</i> or <i>Chamaesyce fendleri</i> may be present. The introduced annual grass <i>Bromus tectorum</i> and several other exotic or invasive species such as <i>Bromus diandrus ssp. rigidus, Schismus barbatus, Salsola kali, Helianthus annuus, Sisymbrium altissimum</i>, or <i>Tribulus terrestris</i> may be present to abundant, especially on disturbed riparian stands. Occasional <i>Brickellia</i> spp. or other shrubs may occur, but they are not dense enough to form a shrub layer. This plant association is described from the Uinta Basin and Colorado Plateau where it occurs on alluvial terraces of major rivers, sandy upper stream terraces along intermittent washes, and on sand deposits on mesas and plains. Elevation ranges from 1158 to 1630 m. Soils are loamy sands and sandy loams derived from alluvium, eolian deposits or sandstone residuum. Sites have generally been disturbed by flooding, shifting sands, livestock grazing, or human recreation.  Accession Code: urn:lsid:vegbank.org:commConcept:31599-{274382F1-3F72-4377-A499-94590167D3E8} Plot-observations of this Community Concept: 3
