Name: Populus tremuloides / Juniperus communis Forest
Reference: Western Ecology Working Group of...
Description: This association is known from the mountains of Colorado, Wyoming and Montana, where it occurs in two differing environments: (1) warm, dry sites near the margins of bunchgrass meadows and (2) swales, broad benches or dry flats acting as frost pockets, or where subject to cold-air drainage. This association occurs on nearly all exposures, gentle to moderate slopes (10-18%), and elevations from 9000 to 9720 feet. Stands have a somewhat closed to closed canopy of trees 5-20 m tall, that is dominated or codominated by the cold-deciduous, broad-leaved tree Populus tremuloides. Scattered conifer trees such as Pseudotsuga menziesii and species of Pinus, Picea, and Abies may also be present. Common shrubs include Juniperus communis, Acer glabrum, Mahonia repens (= Berberis repens), Dasiphora fruticosa ssp. floribunda, Arctostaphylos uva-ursi, Paxistima myrsinites, Rosa woodsii, Symphoricarpos oreophilus, and dwarf-shrubs Mahonia repens and Vaccinium myrtillus. The herbaceous layer is not abundant.
