  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.

  Citation × Citation Citation Abstract Copy Title: Classification of native vegetation of Oregon Author: Institute for Natural Resources, Christy, John A., Titus, Jonathan A., Oregon Natural Heritage Information Center, Kagan, James S., Murray, Michael P. This classification lists the native plant associations known to occur in Oregon, and includes both successional and climax vegetation types that were an important part of the presettlement landscape of Oregon. It serves as an index to the diversity, distribution and relative rarity of the state's native plant associations, and as a guide to their literature. Plant assocations are listed by scientific name, followed by common name and acronym. Listings include the global and state rank of each association, the ecoregion in which it occurs, its status as wetland or upland, and references describing the association. A bibliography lists all cited references. The classification is presented in a spreadsheet format, but can also be imported into a database format. Published and unpublished reports were the primary sources for the classification. Descriptions supported by quantitative data were used whenever possible. Publications from other states or provinces in the Pacific Northwest were used for associations known to occur in, but not described from Oregon. Sampling methods and concepts of species and associations differ greatly among researchers. To accommodate variation occurring in the field, some associations have been lumped.
