CEGL003314 Equisetum arvense Wet Meadow
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Field Horsetail Wet Meadow
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: Habitat is seepy alluvial fans, slopes, wet meadows, and fens. This is mostly a low- to mid-elevation association, often occurring in sites with some groundwater movement. It is often small-patch size in water tracks, and the plots suggest considerable inclusions of upland species that may be an artifact of plot size or configuration in a sinuous wetland configuration. Discounting the trees and shrubs that are mostly peripheral to the stand, the primary species in the herb layer is Equisetum arvense, with average cover of 88% and cover ranging from 80-95%. Other wetland associates with lesser cover include Hypericum anagalloides and Mimulus guttatus. Of the other 25 species, nearly half are upland taxa and should not be part of this association. This is a widespread and well-known association in other regions and obviously undersampled locally.
