CEGL003369 Carex lyngbyei Salt Marsh

Type Concept Sentence: No Data Available

Common (Translated Scientific) Name: Lyngbye''s Sedge Salt Marsh

Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: This community type occurs along the lower Columbia River, Washington, as far upriver as Fisher Island near Longview. It occurs on floodplains subject to daily freshwater tidal inundation and is typically laced with sinuous tidal creeks. The substrate is mud. This is a heterogeneous community type dominated by Carex lyngbyei. It forms narrow bands or extensive marsh flats. In some places examples of this community type have been degraded by grazing and invasion of Phalaris arundinacea, but in most cases it appears to be below the line of Phalaris arundinacea invasion. Additional species include Bidens cernua, Boltonia asteroides, Caltha palustris, Deschampsia cespitosa, Eleocharis palustris, Equisetum fluviatile, Juncus oxymeris, Sagittaria latifolia, Sium suave, and Typha angustifolia.

Rationale for Nominal Species or Physiognomic Features: No Data Available

Classification Comments: With further study this community type from Washington may be split into separate Carex lyngbyei- and Bidens cernua-dominated community types. This community type is most similar to the Carex lyngbyei community type which occurs in the surge plain in southwestern Washington and is distinct from the Carex lyngbyei community type that occurs in salt marshes. Christy (1993) listed several references for a freshwater tidal Carex lyngbyei community.
