Regional gradient analysis and spatial pattern of woody plant communities in Oregon

Creator:: Ohmann, Janet L.
Abstract:: Knowledge of regional-scale patterns of plant community structure and controlling factors is largely qualitative and based on numerous local studies. Data from a subsample of 10,000 field plots were used to quantify and map compositional gradients of woody plant communities across Oregon forests. Canonical correspondence analyses explained 9-14% of the...

The quantity and composition of ground vegetation in different light environments under a Douglas-fir, Pseudotsuga menziesii (Mirb) Franco, stand in the Oregon Coast Range

Creator:: Temmes, Eeva Karin Marianna
Abstract:: The relationship between ground vegetation and light intensity under a 60 to 65-year-old Douglas-fir forest was investigated. Biomass and height of ground vegetation were measured and cover was estimated on small sample units (30 centimeters in diameter) on permanent research plots, one-acre in size, on the George T. Gerlinger Experimental...

Field guide to riparian plant communities in northwestern Oregon

Creator:: USDA Forest Service Pacific Northwest Region, McCain, Cindy, Christy, John A., Oregon Natural Heritage Information Center, and Institute for Natural Resources
Abstract:: This field guide combines classifications of common streamside plant communities and native freshwater wetland communities in Northwest Oregon. It is a condensed version of two separate works which are both available on the CD that accompanies this book. The information is also available for reference or to download as a...

Classification of native vegetation of Oregon

Creator:: Kagan, James S., Christy, John A., Murray, Michael P., Titus, Jonathan A., Oregon Natural Heritage Information Center, and Institute for Natural Resources
Abstract:: 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...

Analysis and prediction of patterns in lichen communities over the western Oregon landscape

Creator:: Peterson, Eric B.
Abstract:: The diverse lichen flora of the Pacific Northwest is being impacted by population growth and by forest management practices. Accumulating information about our lichen flora will improve our conservation strategies. This dissertation first collects information to improve our understanding of how lichen communities vary among forests of differing structure, and...

A preliminary classification of forest communities in the central portion of the western Cascades in Oregon

Creator:: Dyrness, C. T., Franklin, Jerry F., Moir, William H., and U.S. International Biological Program. Coniferous Forest Biome
Abstract:: Forest communities in the central portion of Oregon's western Cascades are arrayed along moisture and temperature gradients. With the aid of reconnaissance data and a computerized ordination technique, 23 forest communities have been provisionally recognized in two distinct forest zones, the Tsuga heterophylla (300 to 1050 m in elevation) and...
