CEGL001831 Dulichium arundinaceum Shore Fen
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Threeway Sedge Shore Fen
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This herbaceous vegetation association is known from British Columbia, Canada, the western states of California, Idaho, Montana, Oregon, Washington, and possibly occurs in Wyoming. The community occurs over fibrous peat or mineral soils in areas that are seasonally or permanently flooded with shallow water. In Idaho and Montana stands are typically present in fens and may occur on fixed or floating mats. West of the Cascades it occurs in freshwater marshes as well as in fens. Dulichium arundinaceum may occur as a monoculture, but stands are sometimes moderately species-rich with Carex viridula ssp. viridula, Carex exsiccata, Carex aquatilis, Carex limosa, Carex lasiocarpa, Eleocharis palustris, Juncus arcticus ssp. littoralis, Lycopus uniflorus, Mentha arvensis, Menyanthes trifoliata, Comarum palustre, Rhynchospora alba, Schoenoplectus subterminalis, and/or Utricularia macrorhiza present.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This plant association is described based on limited data in Idaho and Montana and is uncommon in these states (Pierce 1986, Bursik and Moseley 1995). It is more common west of the Cascades in Oregon and Washington (Christy 1993, Kunze 1994, Christy et al. 1998, Titus and Christy 1996a). A comparison of data from stands east and west of the Cascades may indicate that two distinct associations should be recognized.

Environmental Description: The community occurs over fibrous peat or mineral soils in areas that are seasonally or permanently flooded with shallow water. In Idaho and Montana stands are typically present in fens and may occur on fixed or floating mats. West of the Cascades it occurs in freshwater marshes as well as in fens.
Geographic Range: This association is a minor type in the western United States of Montana, Idaho, Oregon, Washington, California and possibly Wyoming. It is also reported from British Columbia, Canada, and Alaska (Christy 2004).
