Name: Cercocarpus ledifolius / Pseudoroegneria spicata Scrub
Reference: Western Ecology Working Group of...
Description: This small-patch association occurs in isolated stands throughout the interior western U.S. Sites are generally located in gentle to moderately steep, dry, rocky habitats, where soils are patchy and shallow and fracturing allows <i>Cercocarpus</i> roots to penetrate the underlying bedrock. Elevations range from 1400 m (4600 feet) in Montana to over 2600 m (8530 feet) in western Colorado. The substrate is often limestone, less often quartzite or sandstone. This tall shrubland is dominated by <i>Cercocarpus ledifolius</i>, often treelike in form. Scattered <i>Juniperus osteosperma, Juniperus scopulorum</i>, and <i>Pinus edulis</i> may also occur in the canopy. Total canopy cover is between 30 and 60%. There is usually no developed shrub layer, but <i>Amelanchier utahensis, Amelanchier alnifolia, Artemisia nova, Artemisia tridentata, Physocarpus monogynus, Symphoricarpos oreophilus</i>, and <i>Juniperus communis</i> may be present. <i>Prunus virginiana</i> is absent or has very low cover. Herbaceous species have relatively high cover (20-30%), dominated by <i>Pseudoroegneria spicata</i>. Other graminoid species with significant cover include <i>Achnatherum hymenoides</i> and <i>Hesperostipa comata</i>, and common forbs include <i>Artemisia frigida, Balsamorhiza sagittata, Hackelia patens, Mertensia oblongifolia, Phlox hoodii</i>, and <i>Petradoria pumila</i>.
