Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Red Alder / Common Ladyfern - British Columbia Wild Ginger Swamp Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: Found only along two streams on the northwestern slope of the Blue Mountains of Oregon and Washington and reported in another drainage in the Clearwater Mountains of Idaho, this riparian forest community typically appears on streamsides and wet seeps in the grand fir zone. Elevations range from 610 to 1070 m (2000-3500 feet). This riparian association is dominated by Alnus rubra, typically the sole tree species in a closed canopy. Abies grandis or Pseudotsuga menziesii dominate the forests on adjacent uplands. This association is floristically diverse and characterized by high cover of Athyrium filix-femina plus other moist sites species, such as Asarum caudatum, Glyceria striata, Tiarella trifoliata var. unifoliata, and Carex deweyana. It may have a tall deciduous shrub layer dominated by Physocarpus capitatus and/or Cornus sericea.

Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: A definite unit that is well-described, the central concept is Crowe and Clausnitzer''s (1997) Alnus rubra / Athyrium filix-femina Community Type. This is a disjunct Rocky Mountain version of typical Cascadian red alder types. This may need a careful review with Idaho Alnus rubra types.
