Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Sitka Alder / Devil''s-club Shrub Swamp
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association occurs in the Cascade Range and Olympic Mountains at middle elevations 1125-1410 m (3700-4600 feet). Sites are usually moderate to steep slopes, usually on talus, debris fields or avalanche chutes with subsurface irrigation. The well-developed tall-shrub layer is dominated by Alnus viridis ssp. sinuata with a slightly lower shrub layer characterized by >10% cover of Oplopanax horridus. Several other shrub species, especially Rubus spectabilis and Sambucus racemosa, can occur in abundance. Frequently occurring herbs include Athyrium filix-femina, Achlys californica, Achlys triphylla, Claytonia sibirica. Streptopus lanceolatus var. curvipes, Maianthemum stellatum, and Viola glabella. Callitropsis nootkatensis is the most constantly occurring tree species but it is never prominent.
