Name: Populus tremuloides Southern Rocky Mountain Woodland & Scrub Alliance
Reference: NatureServe Biotics 2019
Description: Communities of this alliance are characterized by open woodlands or regenerating stands of <i>Populus tremuloides</i>. Conifers such as <i>Pinus ponderosa</i> and <i>Pseudotsuga menziesii</i> from the surrounding mixed conifer stands can be interspersed in the canopy. In the open canopy, shrub cover is often dense and may include <i>Ceanothus fendleri, Holodiscus dumosus, Rhus trilobata, Ribes leptanthum, Robinia neomexicana</i>, and <i>Symphoricarpos oreophilus</i>. The herbaceous layer ranges from sparse to dense and is typically graminoid-dominated. Species include <i>Carex rossii, Carex siccata, Piptatheropsis micrantha</i>, and <i>Poa fendleriana</i>. This alliance is known only from Grand Canyon National Park and El Malpais National Monument on plateaus and gentle to steep slopes. Elevations range from to 2350-2690 m. Communities occur on all aspects and slopes may be gentle to steep.
