CEGL002645 Populus angustifolia / Salix (monticola, drummondiana, lucida) Riparian Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Narrowleaf Cottonwood / (Park Willow, Drummond''s Willow, Shining Willow) Riparian Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This riparian woodland association occurs at moderate elevations (2400-2700 m) on all types of active floodplains throughout the Colorado Plateau, Great Basin and San Juan Mountains of Colorado, Utah and Nevada. Stands generally occur within 0.3-1.4 m (1-4.5 feet) of the active channel elevation. All sites show signs of active flooding; soils are somewhat deep (1 m) loamy to clay soils over very coarse alluvial layers. This is an early- to mid-seral stage of more mature Populus angustifolia-dominated plant associations, with an upper canopy dominated by young (12-53 cm dbh) Populus angustifolia (25-80% cover) and a diverse understory of willows and other shrubs. The shrub understory (15-85% cover) consistently includes two or more willow species of the following: Salix exigua, Salix ligulifolia, Salix monticola, Salix lucida ssp. caudata, Salix drummondiana, and Salix geyeriana, although none individually exceeds 10% cover. Other shrubs present may include Rosa woodsii, Ribes spp., Alnus incana, Crataegus rivularis, Dasiphora fruticosa ssp. floribunda, and/or Symphoricarpos spp., with none exceeding 5% cover. The herb layer is generally low in total cover (10-30% cover forbs, 10-15% cover graminoids). Common herbaceous species include Maianthemum stellatum, Erigeron spp., and the introduced species Trifolium spp., Poa pratensis, and Bromus inermis.
