CEGL000646 Populus angustifolia / Acer grandidentatum Riparian Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Narrowleaf Cottonwood / Bigtooth Maple Riparian Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: The association has a limited range of distribution and is known from southeastern Idaho and northeastern Utah. It occurs on gently to moderately sloping stream terraces at elevations between 1500 and 2000 m. The overstory is usually dominated by Populus angustifolia with occasional codominance by Acer negundo. Acer grandidentatum creates a low tree layer. Shrubs are typically sparse and may include Mahonia repens, Paxistima myrsinites, or Symphoricarpos oreophilus. Herbaceous cover is variable and common species include Osmorhiza berteroi, Maianthemum stellatum, Elymus glaucus, and the invasive grass Poa pratensis.
