CEGL000638 Alnus rubra / Polystichum munitum Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Red Alder / Western Swordfern Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: [From Crawford et al. (2009)]: This association is described from the Puget Lowlands, Mount Rainier and the Olympic Mountains. It occurs on upland slopes (varying steepness) usually with mesic, well-drained soils. It is not associated with riparian landforms, rather it is result of succession after fires, logging, landslides or slope failures. This forest association is dominated by Alnus rubra. The herb layer is always dominated by Polystichum munitum. Other frequently occurring species include Claytonia sibirica, Athyrium filix-femina, Anaphalis margaritacea, and Tellima grandiflora. If present, a well-developed shrub layer is usually dominated by Rubus spectabilis.

Classification Comments: Sites found on landslide deposits, especially at lower elevations, are similar to ~Acer macrophyllum - Alnus rubra / Polystichum munitum - Tellima grandiflora Forest (CEGL003334)$$ but differ in no or low cover of Acer macrophyllum, Holodiscus discolor, Rubus parviflorus, Blechnum spicant, and Tiarella trifoliata.
