CEGL003420 Myrica gale - Spiraea douglasii / Sphagnum spp. Fen
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Sweetgale - Rose Spirea / Peatmoss species Fen
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association is a shrub-dominated peatland (sphagnum bog or poor fen) that occurs around low-elevation lakes and very slowing-moving streams on the northwestern Olympic Peninsula of Washington and Vancouver Island, British Columbia. It is saturated year-round and in some cases is seasonally flooded with minerotrophic water. Soils are sphagnum, fibrous and heath peat. The dense deciduous shrub layer is dominated by Myrica gale and codominated by Spiraea douglasii. The herbaceous layer is characterized by Trientalis europaea ssp. arctica, and is otherwise variable. The moss layer is dominated by Sphagnum spp., usually >40% cover. The combination of dominant Myrica gale and abundant Spiraea douglasii and Sphagnum is diagnostic.
