Name: Populus tremuloides - Abies lasiocarpa / Carex geyeri - Calamagrostis rubescens Forest
Reference: NatureServe Biotics 2019
Description: This is a widely distributed forest association from Idaho and Wyoming to southern Utah. It is documented to occur between 1800 and 3000 m (6000-10,000 feet) elevation. This type occurs on gentle and moderately steep slopes and on igneous- and sedimentary-derived soils. In one stand soils are described as poorly drained silt loam with high organic matter. The prominence of either <i>Carex geyeri</i> or <i>Calamagrostis rubescens</i> in the herbaceous layer and the lack of a distinct shrub layer characterize the undergrowth of this type. The tree layer is a variable mixture of <i>Populus tremuloides</i> and either <i>Abies lasiocarpa</i> or <i>Picea engelmannii</i> or both. Other conifers may be present, including <i>Pseudotsuga menziesii</i> and <i>Pinus contorta</i>. Shrubs can occur within the type; no single characterizing species is prominent. Common shrub species present can be <i>Symphoricarpos oreophilus, Lonicera utahensis, Rosa woodsii</i>, and <i>Mahonia repens</i>. Additional herbaceous species include <i>Elymus glaucus, Bromus ciliatus, Thalictrum fendleri, Achillea millefolium, Osmorhiza berteroi, Taraxacum officinale, Arnica cordifolia, Astragalus miser, Fragaria virginiana, Galium boreale, Geranium viscosissimum</i>, and <i>Lathyrus</i> spp.
