CEGL000229 Salix farriae / Eleocharis quinqueflora Shrub Fen
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Farr''s Willow / Few-flower Spikerush Shrub Fen
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This infrequent bog and poor fen association appears between 579-1525 m (1900-5000 feet) in northeastern Washington and the northernmost East Cascades. It is associated with very low-gradient streams and lakes in very broad, very low-gradient valleys. This bog association has deep moss-peat soils that usually remain saturated throughout the growing season and with little surface water exposed. These are anaerobic soils with poor nutrients, and they are much warmer than other low willow associations in the region. This association has low vascular species diversity and, as sampled in Washington, no species appears in all plots. The species that appear in over half the samples are: the less than 2-m tall willow Salix farriae, the forb Comarum palustre, the graminoids Carex utriculata, Carex limosa, and Eleocharis quinqueflora, and seedlings of Picea engelmannii. Species that occur in 33% of plots are Salix planifolia ssp. planifolia, Betula glandulosa, Viola macloskeyi, Calamagrostis canadensis, Carex diandra, and Eriophorum angustifolium ssp. angustifolium.

Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This includes Kovalchik''s (1993) 4 plots of Salix farriae / Eleocharis pauciflora. Kovalchik (2001, p. 224) concluded with more plots (6) that this association is a bog, whereas ~Salix (farriae, planifolia) / Carex utriculata Wet Shrubland (CEGL001228)$$ is a fen. Kovalchik (2001) reports the diagnostic species as Salix farriae, Eleocharis quinqueflora, Eriophorum spp., Carex limosa, Carex pauciflora, and Carex diandra.
