Name: Pinus contorta / Juniperus communis Woodland Reference: Western Ecology Working Group of... Description: This woodland association occurs in the upper montane and subalpine zone throughout much of the Rocky Mountains, although it is more common from along the Continental Divide east where climates are often drier. Sites are warm and dry and occur on nearly level benches, and gentle to very steep slopes. Aspects vary from south at high elevations to north aspect at lower elevations in canyons. Substrates are typically rocky, shallow to moderately deep, well- to excessively well-drained, gravelly or coarse-sandy loam or clay loam. Parent materials are variable, but are more often igneous or metamorphic rocks. The vegetation is characterized by an open to moderately dense (30-70% cover) tree canopy that is often solely dominated by Pinus contorta. However, scattered Abies lasiocarpa, Picea engelmannii, Pinus albicaulis, Pinus flexilis, Pseudotsuga menziesii, or Populus tremuloides trees may be present in some stands, especially in the subcanopy. The understory is typically depauperate and dominated by the conspicuous dwarf-shrub Juniperus communis with 5-15% cover. Arctostaphylos uva-ursi is often present with low cover. Other shrubs may be present in low cover. The herbaceous layer is usually sparse with a few scattered species. Diagnostic of this association is the dominance of Pinus contorta in the tree canopy with Juniperus communis dominating the understory.  Accession Code: VB.CC.23018.PINUSCONTORTAJU Plot-observations of this Community Concept: 0
