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 Juniperus occidentalis presence varying from as little as 2 individuals per acre to 32% canopy cover. The sparse to moderately dense graminoid layer is composed of Pseudoroegneria spicata, Festuca idahoensis, and Poa secunda 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 Artemisia tridentata accounting for less than 4% cover. This association is distinguished from similar associations by the dominance of Pseudoroegneria spicata in the grass layer and by the lack of Artemisia tridentata or Purshia tridentata which are present in most Juniperus occidentalis stands.
