Name: A.1502
Reference: EcoArt 2002
Description: Vegetation within the ~~Juniperus osteosperma$ Wooded Herbaceous Alliance (A.1502)$$ is described only from the semi-arid Basin and Range Province of southern Idaho. In this region it occurs from 1800-2200 m in elevation. Average annual precipitation is 25-40 cm with a peak in early summer. Soils are rocky, well-drained, and derived from limestone parent materials. These communities are characterized by an open canopy of ~Juniperus osteosperma$, usually as the only tree species. ~Cercocarpus ledifolius$ is a common associate on thin soils near rock outcrops. Shrub associates include ~Artemisia tridentata, Artemisia nova$, and ~Krascheninnikovia lanata$. Perennial bunch grasses dominate the herbaceous layer, with ~Pseudoroegneria spicata, Leymus ambiguus$, and ~Hesperostipa comata (= Stipa comata)$ being the most common species. Adjacent vegetation is ~Artemisia$ shrub-steppe at the lower elevation margin and ~Cercocarpus ledifolius$ shrublands on rocky outcrops.
