  Citation × Citation Citation Abstract Copy Title: Native freshwater wetland plant associations of northwestern Oregon Author: Institute for Natural Resources, Christy, John A., Oregon Natural Heritage Information Center This guide provides keys, descriptions, and stand tables for 122 native freshwater plant associations (14 forest and woodland, 28 shrub, 78 herbaceous, 2 nonvascular) in northwestern Oregon, based on analysis of data from 1,992 plots distributed throughout the study area. Descriptions are provided for eight other plant associations for which there are no plot data. Data were also not available for 114 additional associations reported from the study area (Kagan et al. 2000). The study area includes the north half of both the Coast Range and Western Cascade ecoregions, and all of the Willamette Valley. Vegetation is classified according to the National Vegetation Classification System, and plant associations are assigned to ecological systems that are currently being developed on a nationwide level.
