CEGL000484 Vaccinium cespitosum - (Salix farriae) / Danthonia intermedia Wet Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Dwarf Bilberry - (Farr''s Willow) / Timber Oatgrass Wet Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This short shrubland occurs along the dry transitions of alpine/subalpine wetlands that are associated with meandering streams and fen-shrublands in the western Thompson-Okanogan Plateau (Northeast Cascades). It was sampled at 1784 and 2010 m (5850-6590 feet) elevation in low-gradient, broad and moderately broad valleys. Soils were loamy that dry relatively deep. Vaccinium cespitosum codominates an open short-shrub layer with slightly taller shrubs, either Salix farriae, Salix planifolia, or Betula glandulosa. The ground cover is primarily Danthonia intermedia with scattered Calamagrostis canadensis and Achillea millefolium. Both wet-site species Carex scopulorum var. bracteosa and Carex nigricans and drier-site species Festuca saximontana, Phleum alpinum, or Trisetum spicatum may be present but never abundant.

Classification Comments: This association is based on Kovalchik''s (2001) Salix farriae / Danthonia intermedia association. It is a tentative type, given the small number of stands sampled. This type occurs in somewhat wet environments, which is why Salix farriae is included in the name, and it may be more appropriately placed in a wetland alliance. Until further inventory and classification work are done to clarify the relationship of this type to other Salix farriae or Vaccinium cespitosum types, it has been placed in an existing upland alliance.
Kovalchik''s (2001) Danthonia intermedia and Festuca ovina associations are similar to this type, in that most plots also have Vaccinium cespitosum in them, sometimes with cover up to 25%. However, the associated species in these two Kovalchik (2001) types are more subalpine dry meadow in character. ~Vaccinium cespitosum - (Salix farriae) / Danthonia intermedia Wet Shrubland (CEGL000484)$$ is clearly a transitional community between wetter Salix fens or bogs and drier subalpine to alpine grass-dominated meadows. According to Kovalchik (pers. comm. 2002), this type is found on the margins of Salix farriae / Carex scopulorum var. prionophylla wetland basins in the transition to drier soils and usually the Danthonia- or Festuca-dominated associations.
