Populus angustifolia / Rosa woodsii Forest | Western Ecology Working Group of...
click to update datacart
Name: Populus angustifolia / Rosa woodsii Forest Reference: Western Ecology Working Group of... Description: This deciduous riparian forest occurs on stream terraces and adjacent floodplains in the LaSal and Abajo mountains in southeastern Utah, the west slope of the Wasatch Range in central Utah, in western Wyoming, and in various mountain ranges in Nevada. It may also occur in Colorado. Elevation ranges from 1780-2300 m. Substrates are moderately well-drained alluvial soils derived from sandstone or other sedimentary rock. The community is one of the drier <i>Populus angustifolia</i> plant associations. This association has a closed upper tree canopy that is dominated by <i>Populus angustifolia</i>. Other tree species may include <i>Quercus gambelii, Populus tremuloides</i>, and an occasional <i>Juniperus osteosperma</i> or other upland tree species. <i>Prunus virginiana</i> and <i>Salix bebbiana</i> may form a tall-shrub layer, especially streamside. A dense short-shrub layer dominated by <i>Rosa woodsii</i> or <i>Rosa nutkana</i> is diagnostic of this type. <i>Symphoricarpos oreophilus</i> is often present and occasionally codominant. <i>Rhus trilobata, Mahonia repens</i>, or <i>Cornus sericea</i> are present in some stands. The vine <i>Clematis ligusticifolia</i> is abundant in some stands. The herbaceous layer is generally sparse but may be denser in openings where the introduced grasses <i>Poa pratensis</i> and <i>Agrostis stolonifera</i> and the native <i>Elymus glaucus</i> are dominant. Common native forbs include <i>Maianthemum stellatum, Thalictrum fendleri, Osmorhiza berteroi (= Osmorhiza chilensis), Geranium richardsonii</i>, and <i>Galium boreale</i>. The introduced forb <i>Taraxacum officinale</i> is often also present. The dense short-shrub layer dominated by <i>Rosa</i> spp. separates this association from other <i>Populus angustifolia</i> riparian forests. If present, <i>Cornus sericea</i> is always a minor component.  Accession Code: VB.CC.33019.CEGL000653 Plot-observations of this Community Concept: 0
