Name: Pinus contorta / Jamesia americana Forest
Reference: NatureServe Biotics 2019
Description: This association is well-documented in Rocky Mountain National Park where it typically occurs on somewhat steep to steep (26-100%), north- or east-facing midslopes between 2550 and 2900 m (8370-9520 feet) elevation. Surficial geology is granitic and may exist as exposed rock in as much as 10-35% of the surface area. Soil texture typically is sandy loam and is moderately well-drained to rapidly drained. Litter and duff layering may comprise 35-70% of the surface area of the stand. The forest canopy of this association is typically 10-15 m tall and provides coverage over 50-70% of the stand. The tree canopy is strongly dominated by <i>Pinus contorta</i> (40-70%), and occasionally <i>Pseudotsuga menziesii</i> may be present with moderate cover. <i>Jamesia americana</i> dominates the understory shrub stratum with coverage ranging from 20-40%. Other shrubs that may be present include <i>Juniperus communis, Populus tremuloides, Shepherdia canadensis, Acer glabrum, Arctostaphylos uva-ursi, Mahonia repens, Physocarpus monogynus, Ribes montigenum, Rosa woodsii</i>, and <i>Vaccinium myrtillus</i>; however, few rarely reach &gt;5% cover. There is no distinct herbaceous layer in this association, though forbs and graminoids do exist in low concentrations.
