Name: Juniperus osteosperma Woodland Alliance
Reference: Western Ecology Working Group of...
Description: This woodland alliance is distributed across the Intermountain West from the eastern Sierra Nevada to the central and southern Rocky Mountains. Stands occur on middle mountain slopes of the many mountain ranges and plateaus of the region above areas of cold-air drainage in high intermountain basins. Vegetation included in this alliance is characterized by an open tree canopy of Juniperus osteosperma, quite often in association with Pinus monophylla or Pinus edulis. Cercocarpus ledifolius is a common associate in these interior stands. Scattered Pinus ponderosa, Pinus flexilis, Pinus aristata, or Pseudotsuga menziesii trees may be present where stands grade into montane coniferous forest. If present, the shrub layer may be composed of Artemisia tridentata, Artemisia arbuscula, Artemisia nova, Symphoricarpos oreophilus, Amelanchier alnifolia, Cercocarpus intricatus, Cercocarpus montanus, Chrysothamnus spp., Quercus gambelii, Prunus virginiana, or Purshia tridentata. The herbaceous layer if present is usually sparse and dominated by cespitose perennial grasses, including Pseudoroegneria spicata, Festuca idahoensis, Pleuraphis jamesii (= Hilaria jamesii), Achnatherum hymenoides (= Oryzopsis hymenoides), Elymus elymoides, and Stipa spp. Diagnostic of this alliance is an open tree canopy greater that 25% cover that is dominated by Juniperus osteosperma.
