Western Ecology Working Group of...
Description:
This plant association is found in narrow bands on the floodplains and benches of montane streams (1900-2700 m) in Colorado and New Mexico, primarily in the Southern Rocky Mountains. Stands occur along narrow, fast-moving stream reaches in montane areas. It is characterized by a dense stand of Alnus incana lining the streambank with a variable canopy of Populus angustifolia. Populus angustifolia is always present, although sometimes only as a sapling. A variety of riparian and upland tree species may also be present, including Populus X acuminata, Populus tremuloides, Pseudotsuga menziesii, Juniperus scopulorum, Pinus ponderosa, Abies concolor, or Picea pungens. Alnus incana is the most abundant shrub within the stand with a minimum of 10% cover. Other shrubs may include Salix bebbiana, Salix monticola, Salix drummondiana, Salix ligulifolia (= Salix eriocephala var. ligulifolia), Salix lucida ssp. caudata, Salix exigua, Cornus sericea, Rosa woodsii, Acer glabrum, and Betula occidentalis. Herbaceous growth is generally sparse. Herbaceous species include Equisetum arvense, Heracleum maximum, Maianthemum stellatum, Calamagrostis canadensis, Cardamine cordifolia, Carex rossii, Carex praegracilis, and Carex nebrascensis.
