Name: Juniperus occidentalis / Pseudoroegneria spicata Wooded Herbaceous Vegetation
Reference: Western Ecology Working Group of...
Description: This association is a broadly defined open steppe community which is widespread in eastern Oregon, somewhat restricted in Idaho, and may occur in California, Washington, and Nevada. Stands occur at elevations of 1070-1680 m (3500-5500 feet) on all aspects and slopes. Soils are loams, clay loams, and silt loams that are shallow and stony. About 55% of the surface is bare of vegetation. Vegetation is typically dominated by a graminoid layer with <i>Juniperus occidentalis</i> presence varying from as little as 2 individuals per acre to 32% canopy cover. The sparse to moderately dense graminoid layer is composed of <i>Pseudoroegneria spicata, Festuca idahoensis</i>, and <i>Poa secunda</i> with 3-30%, 0-20%, and 0-28% cover, respectively. Bare ground can occupy as much as 51% of the ground cover. Shrubs are sparse with <i>Artemisia tridentata</i> accounting for less than 4% cover. This association is distinguished from similar associations by the dominance of <i>Pseudoroegneria spicata</i> in the grass layer and by the lack of <i>Artemisia tridentata</i> or <i>Purshia tridentata</i> which are present in most <i>Juniperus occidentalis</i> stands.
