Name:
Acer glabrum Drainage Bottom Wet Shrubland
Reference:
NatureServe Biotics 2019
Description:
This shrubland association occurs in major upland drainage bottoms in the mountains of Montana, Wyoming, Colorado, Nevada and California at elevations of 1400 to 2620 m (4590-8600 feet) in the north extent and 2500 to 2620 m (8200-8600 feet) in the south. Sites are moderately sloping (10-20%) and typically found on the cooler north and east aspects. Substrates are relatively moist, gravelly soils. Vegetation is characterized by a relatively dense tall-shrub layer, dominated by the cold-deciduous shrub <i>Acer glabrum</i>, sometimes with abundant <i>Prunus virginiana</i> and occasional <i>Populus tremuloides</i> trees present. Scattered <i>Populus tremuloides</i> saplings, <i>Alnus incana, Betula occidentalis</i>, and <i>Salix bebbiana</i> may also be present in this layer. An open to moderately dense short-shrub layer is often present and composed of a variety of shrubs, such as <i>Artemisia frigida, Juniperus communis, Mahonia repens, Populus tremuloides</i> seedlings, <i>Philadelphus lewisii, Ribes</i> spp., <i>Rosa woodsii, Rubus</i> spp., <i>Symphoricarpos</i> spp., or <i>Sambucus racemosa</i>. The moderately dense to dense (50-90% cover) herbaceous layer may be dominated by either perennial forbs or grasses and is often diverse, with <i>Bromus hordeaceus, Calamagrostis canadensis</i>, and mesic forbs such as <i>Heracleum</i> spp., <i>Maianthemum</i> spp., <i>Osmorhiza</i> spp., <i>Ranunculus uncinatus, Thalictrum fendleri, Galium aparine</i> and <i>Stellaria media</i> present.
