Common (Translated Scientific) Name: Narrowleaf Cottonwood / Mountain Big Sagebrush / Sulphur-flower Buckwheat Dry Outwash Riparian Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association is documented only from Grand Teton National Park, Wyoming, on the Snake River floodplain and along Pilgrim Creek. The riparian woodland occurs on the valley floor at elevations of 1970 and 2100 m (6455-6880 feet). The soils are well-drained sandy loams. It is a phreatophytic woodland with an overstory canopy of Populus angustifolia tapping into the alluvial water table, while surface is well-drained sandy loam with coarse alluvial cobbles. Consequently, the understory canopy is a mix of mesic riparian and upland species. The shrub layer is composed of Artemisia tridentata, Amelanchier spp., Mahonia repens, and Symphoricarpos spp. The herbaceous undergrowth is dominated by forbs, but some graminoid genera occur, including Carex and Elymus. Eriogonum umbellatum is the dominant forb. Other forbs present include Achillea millefolium, Arabis spp., Collomia linearis, Lomatium ambiguum, Packera streptanthifolia, and Sedum lanceolatum.
