Hierarchy Level: Association
Type Concept: Habitat of this herbaceous vegetation of western Oregon and Washington is low-elevation (2-152 m [8-500 feet]) marsh and mudflats along low-gradient streams and around shallow ponds. Soil is seasonally flooded to perennially saturated silt loam. The association is strictly herbaceous and dominated by Bidens cernua and a variety of other marsh species that tolerate early-season flooding and summer drying that exposes mudflats with subirrigation. Other typical species present in lesser amounts include Polygonum hydropiperoides, Sagittaria latifolia, Eleocharis palustris, Ludwigia palustris, and Leersia oryzoides, but more than 15 other species are recorded. This association was probably fairly widespread in the Willamette Valley prior to flood control but is now mostly restricted to the Columbia River floodplain in the Vancouver Basin. Prolonged pooling in depressions and freshwater tidal flooding along streams helps to keep invasive Phalaris arundinacea from invading stands.
