Description:
This common black sagebrush association occurs from northern Nevada to Colorado and north to Idaho and Montana. Sites are located on gently to moderately sloping, dry, often windswept hills and ridges that may be oriented to any aspect. Elevation ranges from 1400 to 2610 m (4600-8560 feet). Soils are shallow, gravelly and are often high in calcium carbonate. Rock and gravel cover much of the unvegetated ground surface. The vegetation is characterized by a low-shrub canopy dominated by <i>Artemisia nova</i> with 5 to 30% cover. Other shrubs are generally present, although with very low cover, including <i>Artemisia tridentata, Chrysothamnus viscidiflorus, Grayia spinosa, Symphoricarpos longiflorus</i>, and <i>Gutierrezia sarothrae</i>. Graminoids usually dominate the diverse herbaceous layer, with <i>Pseudoroegneria spicata</i> being the most conspicuous of as many as 10 species, including <i>Poa secunda, Achnatherum hymenoides, Pascopyrum smithii, Koeleria macrantha, Carex filifolia, Elymus trachycaulus, Pleuraphis jamesii</i>, and <i>Hesperostipa comata</i>. Sparse forbs are usually present and may include <i>Phlox hoodii, Crepis acuminata, Astragalus miser, Stenotus acaulis, Phlox diffusa, Artemisia frigida</i>, and <i>Calochortus</i> spp. Some sites have scattered <i>Juniperus osteosperma</i> trees.
