Name: Artemisia tridentata / Achnatherum hymenoides Shrubland
Reference: Western Ecology Working Group of...
Description: This broadly defined sagebrush association is reported from the Great Basin to the western slope of the southern Rocky Mountains, but it likely occurs throughout the Intermountain western U.S. Stands occur in broad valleys in the Great Basin, on midslopes below rimrock on mesatops, on hillslopes, and along drainages and in washes in valley bottoms in the Colorado Plateau and southern Rocky Mountains. Sites are nearly level to moderately steep ranging from 1525-1677 m elevation in the Great Basin and Colorado Plateau to 2317-2546 m elevation in the southern Rocky Mountains. Substrates tend to be coarse-textured and likely have low salinity and high sand content, gravel or rocks. The vegetation is characterized by an open to moderately dense (10-50% cover) shrub layer dominated by sagebrush, usually <i>Artemisia tridentata ssp. vaseyana, Artemisia tridentata ssp. tridentata</i>, or with subspecies unspecified. A typically open herbaceous layer is characterized by the large bunchgrass <i>Achnatherum hymenoides</i>. Other shrubs present may include low cover of <i>Artemisia frigida, Chrysothamnus viscidiflorus, Grayia spinosa, Gutierrezia sarothrae, Opuntia</i> spp., <i>Quercus gambelii</i>, and <i>Rhus trilobata</i>. Scattered trees may also be present. The herbaceous layer provides sparse to moderate cover. Other graminoids present on more diverse sites include <i>Bouteloua gracilis, Elymus elymoides, Hesperostipa comata, Pleuraphis jamesii</i>, and <i>Poa secunda</i>. Forb cover is variable and generally low.
