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 and the west slope of the Wasatch Range in central Utah. It may also occur in Colorado. Elevation ranges from 1900-2200 m. The community is one of the drier Populus angustifolia plant associations. Substrates are well drained, rocky alluvial soil. This association has a closed upper tree canopy that is dominated by Populus angustifolia. Other tree species may include Quercus gambelii, Populus tremuloides and an occasional Juniperus osteosperma or other upland tree species. Prunus virginiana and Salix bebbiana may form a tall-shrub layer especially streamside. A dense short-shrub layer dominated by Rosa woodsii or Rosa nutkana is diagnostic of this type. Symphoricarpos oreophilus is often present and occasionally codominant. Rhus trilobata, Mahonia repens or Cornus sericea are present in some stands. The vine, Clematis ligusticifolia, is abundant in some stands. The herbaceous layer is generally sparse but may be denser in openings where the introduced grasses Poa pratensis and Agrostis stolonifera and the native Elymus glaucus are dominant. Common native forbs include Maianthemum stellatum, Thalictrum fendleri, Osmorhiza berteroi (= Osmorhiza chilensis), Geranium richardsonii and Galium boreale. The introduced forb, Taraxacum officinale is often also present. The dense short-shrub layer dominated by Rosa spp. separates this association from other Populus angustifolia riparian forests. If present, Cornus sericea is always a minor component.  Accession Code: VB.CC.18942.POPULUSANGUSTIF Plot-observations of this Community Concept: 0
