CEGL000633 Alnus rhombifolia / Celtis laevigata var. reticulata Riparian Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: White Alder / Netleaf Hackberry Riparian Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This riparian plant association is described from data collected in the Snake and Salmon river corridors, within the Blue Mountains ecoregional section. The association is described as occurring within a relatively discrete elevational band (275-655 m [900-2150 feet] and 430-655 m [1400-2150 feet], respectively) in the deeply incised terrain of the Snake and Salmon river canyons. The plant association occurs on stable and unstable riparian substrates. The broad-leaved, deciduous forest stands are dominated by Alnus rhombifolia. Celtis laevigata var. reticulata is consistently present. Prunus virginiana and Populus balsamifera ssp. trichocarpa may also be associated. Associated understory shrub species include Cornus sericea, Ribes oxyacanthoides ssp. irriguum, Rosa woodsii, Philadelphus lewisii, Sambucus nigra ssp. cerulea, Amelanchier alnifolia, and Frangula purshiana.

Environmental Description: he association is described as occurring within a relatively discrete elevational band (275-655 m [900-2150 feet] and 430-655 m [1400-2150 feet], respectively) in the deeply incised terrain of the Snake and Salmon river canyons. The plant association occurs on stable and unstable riparian substrates.
Geographic Range: Miller (1976) describes the association as occurring on the Snake and Salmon rivers and their tributaries in Idaho, Oregon and Washington. Mancuso and Moseley (1994) report the association for the Craig Mountain area.
