Reference:
NatureServe Biotics 2019
Description:
These forests and woodlands are primarily distributed in the southern Rocky Mountains, and as far east as Texas. They include evergreen forests dominated by <i>Pseudotsuga menziesii</i>. Canopy associates vary widely depending on geographic location and may include <i>Abies lasiocarpa, Juniperus scopulorum, Pinus contorta, Pinus flexilis, Pinus ponderosa, Pinus strobiformis</i>, and <i>Populus tremuloides</i>. Understories are most often shrub-dominated, but in some associations a layer of graminoids takes prominence. Common dominant shrubs may include <i>Arctostaphylos patula, Arctostaphylos uva-ursi, Artemisia tridentata, Cercocarpus montanus, Holodiscus dumosus, Juniperus communis, Paxistima myrsinites, Physocarpus monogynus, Quercus gambelii</i>, and <i>Quercus x pauciloba</i>. Herbaceous dominants may include <i>Festuca arizonica, Jamesia americana, Muhlenbergia montana, Muhlenbergia straminea</i>, and <i>Poa fendleriana</i>. Elevations range from less than 1000 m in the northern Rocky Mountains to nearly 2900 m in the Southern Rockies and plateaus of the southwestern U.S. Lower elevation stands typically occupy protected northern exposures or mesic ravines and canyons, often on steep slopes. At higher elevations, these forests occur primarily on southerly aspects or ridgetops.
