CEGL003401 Alnus rubra / Petasites frigidus Riparian Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Red Alder / Arctic Sweet-colt''s-foot Riparian Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This red alder forest of western Washington and Oregon has a canopy dominated by Alnus rubra which is sometimes only at shrub height due to its early-successional status. The understory is dominated by Petasites frigidus although other forbs are typically present. Shrubs (other than shrub-height alder) are under 20% cover, if present. This association occurs on well-drained soils at lower to middle elevations on riparian floodplains, bars, or low-lying streambanks. These sites are frequently flooded and/or this community occurs as an early-successional vegetation type.
