Hierarchy Level: Association
Type Concept: This herbaceous vegetation occurs from Oregon to British Columbia. Habitat is gently sloping, silty rivershores exposed at seasonal low flows, between the high water cutbank and the water line. Soils are moist silt loam. No trees are present below the high water cutbank, but Salix fluviatilis and Salix lucida ssp. lasiandra are frequently present at the toe of the cutbank and sometimes form extensive stands along the flat shore adjacent to this association. The exotic Amorpha fruticosa is rapidly spreading along the riverbanks in this habitat (Glad and Halse 1993). The herb layer contains over 20 different species, some exotics and some opportunists on seasonally scoured and inundated shorelines. Euthamia occidentalis is the principal species and forms tall stands with an average cover of 38% and ranging from 30-45%. Most of the other species are incidental and have low cover values but are of interest because some are uncommon except in this habitat.
