  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: Wet Meadow Plant Associations, Malheur National Wildlife Refuge, Harney County, Oregon Author: Christy, John A. Year: 2013 In July 2012, we sampled 131 plots in wet meadow habitat at the southern end of the Malheur National Wildlife Refuge. Analysis of the data identified eleven different plant associations: Alopecurus pratensis, Carex aquatilis var. aquatilis, Carex nebrascensis, Carex pellita, Carex praegracilis, Carex sheldonii, Distichlis spicata, Juncus balticus, Leymus triticoides, Phalaris arundinacea, and Sparganium eurycarpum. Plant associations spanned a wetland gradient from seasonally moist to seasonally or perennially flooded, but surface water had left most stands at time of sampling. Mean Wetland Indicator Status scores help to place the plant associations within gradients in soil moisture and alkalinity. The Alopecurus pratensis and Phalaris arundinacea associations are dominated by exotic, invasive species and appear to be outcompeting native plant associations. Phases of the Carex praegracilis association appear to be replaced by the Alopecurus pratensis association, while the Carex pellita, Juncus balticus, and Leymus triticoides associations may be replaced by the Phalaris arundinacea association. The Carex aquatilis and Sparganium eurycarpum associations were undersampled and provide only an estimate of composition. Most associations are consistent with what has been included in the National Vegetation Classification.

  Citation × Citation Citation Abstract Copy Title: Forested plant associations of the Olympic National Forest Author: Henderson, Jan A., Shaw, David C., Peter, David H., Lesher, Robin D. A potential vegetation classification system is presented for the Olympic National Forest. It is based on a sample of 1046 Reconnaissance and 408 Intensive plots. The hierarchical classification includes sixvegetation series and 64 plant associations. Diagnostickeys are presented to aid in the identification of series and associations. Descriptions are presented for each series and association which are oriented toward the application of this classification for land management objectives. Association descriptions include information about plant species occurrences, including mosses and lichens, mammals, birds, insect pests and diseases. Most descriptions include information on timber productivity and soils. Background information is also presented on the ecology, geology, soils and history of the Olympic Mountains. Key words: vegetation classification, climax vegetation, climax plant communities, plant association, vegetation series, plant community ecology, forest ecology, mosses, lichens, birds, mammals, forest diseases, timber productivity, soil, Olympic Mountains.

  Citation × Citation Citation Abstract Copy Title: Forested plant associations of the Colville National Forest Author: Pacific Northwest Research Station (Portland, Or.), Kelley, Brian F., Smith, Bradley G., Lillybridge, Terry R., Williams, Clinton K. A classification of forest vegetation is presented for the Colville National Forest in northeastern Washington State. It is based on potential vegetation with the plant association as the basic unit. The classification is based on a sample of approximately 229 intensive plots and 282 reconnaisance plots distributed across the forest from 1980 to 1983. The hierarchical classification includes 5 forest tree series and 39 plant associations or community types. Diagnostic keys are presented for each tree series and plant association or community type. Descriptions include information about plant association or community species composition, occurrences, distribution, environment, soils, forest productivity, management implications and relations to other vegetation classifications. Background information is also presented on the ecology, geology, soils, climate, and fire history of the Colville National Forest.

  Citation × Citation Citation Abstract Copy Title: Field guide to the forested plant associations of the Mt. Baker-Snoqualmie National Forest Author: Henderson, Jan A., Shaw, David C., Peter, David H., Lesher, Robin D. A classification of forest vegetation is presented for the Mt. Baker-snoqualmie Forest. It is based on the potential National vegetation and uses the plant association as the basic unit. The classification is based on 2464 sample plots distributed across the Forest from 1979 to 1990. Of these 1963 were in late successional stands over 150 years old. An additional 633 plots were taken in non-forest communities or undescribed plant associations. The hierarchical classification includes 4 forest series, 19 plant association groups, and 60 plant associations. Diagnostic keys are presented to aid in the identification of vegetation series and plant associations. Descriptions are presented for each series and association. Plant association descriptions include information about plant species occurrences, distribution, environment and soils, potential timber productivity, management considerations, and comparisons with similar plant associations.
