Riparian and wetland vegetation of central and eastern Oregon

Creator:: Crowe, Elizabeth A. (Elizabeth Ann), 1963-, Kovalchik, Bernard L., Kerr, Marie Jeannette James, 1968-, Oregon Natural Heritage Information Center, and Institute for Natural Resources
Abstract:: The structure and components of riparian areas influence the rate, amount, and timing of water, nutrients, organic debris, and inorganic materials that enter streams and rivers. The energy of floodwaters and their ultimate volume, timing and erosive power is influenced by the soils, vegetation and geomorphology of fluvial surfaces within...

Coarse woody debris in streams of the Drift Creek Basin, Oregon

Creator:: Veldhuisen, Curt N.
Abstract:: This study examined the occurrence of coarse woody debris (i.e., pieces greater than 0.15 m in diameter and 2.0 m in length) in first- through fifth-order streams located within the Drift Creek Basin of the Oregon Coast Range. Nine "tributary reaches" were surveyed to determine how three land management treatments...

Evaluating the restoration potential of black cottonwood (Populus trichocarpa) from multiple scales of observation, Grande Ronde River Basin, Oregon, USA

Creator:: Hines, Cynthia A.
Abstract:: As a key factor contributing to slope stability, in-stream habitat for aquatic species (e.g., salmonids), nutrient cycling, and corridors for upland species, riparian vegetation and its maintenance is of critical conservation importance. Subsequently, the chronic degradation of aquatic and riparian ecosystems in the semi-arid and arid landscapes of the western...

Denitrification and vegetative uptake in a pasture, poplar and native oak riparian buffer area

Creator:: Brown, Dina E.
Abstract:: Managing riparian buffer zones is a potentially important approach to protecting streams from agricultural pollution. This study was conducted to determine if a pasture, a hybrid poplar (Populus trichocarpa x deltoides) stand, or a native oak (Quercus garryana) forest, had the greatest potential to serve as a nutrient buffer zone....

Effect of riparian areas on the ecological condition of small, perennial streams in agricultural landscapes of the Willamette Valley : research plan, June 1997

Creator:: Moser, Thomas J., Wigington, P.J., Schuft, Michael J., Kaufmann, Phillip R., Herlihy, Alan T., Van Sickle, John, and McAllister, Lynne S.
Abstract:: Little research has been directed toward determining the status and ecological role of riparian areas in agricultural landscapes of the Willamette Valley, Oregon. A research project has been designed to contribute to the development and evaluation of alternative future scenarios and to improve the basic understanding of the role of...

Relations among hydrology, soils, and vegetation in riparian meadows : influence on organic matter distribution and storage

Creator:: Dwire, Kathleen A.
Abstract:: Organic matter dynamics in riparian ecosystems are largely driven by interactions among hydrology, soil, and vegetation. In two riparian meadows, northeast Oregon, I examined the hypothesis that vegetation and soil characteristics in three plant communities - defined as wet, moist, and dry meadow - were strongly influenced by hydrological and...

Historical land use and its impact on Oak Creek, Oregon

Creator:: Yamaguchi, Keiko, 1964-
Abstract:: The purposes of this study were:1) to review the land use history of Oak Creek watershed since European settlement. And 2) to consider the human-caused impacts and their effects associated with different land uses. The study area was classified into three land use patterns: residential,agricultural, and forested areas.Since the European...

Riparian vegetation and abundance of woody debris in streams of southwestern Oregon

Creator:: Ursitti, Victoria L.
Abstract:: Riparian vegetation (trees > 10 cm dbh), woody debris (> 10 cm diam, > 1 m long), channel, and landform characteristics were inventoried in mature (80-150 yrs) and old-growth riparian areas (>250 yrs) selected from small tributaries of the Coos and Coquille River basins in southwestern Oregon. Basal area of...

Comparison of stand development of a deciduous-dominated riparian forest and a coniferous-dominated riparian forest in the Oregon Coast Range

Creator:: Poage, Nathan Jeremy
Abstract:: Riparian forests in the central Oregon Coast Range vary along a coniferous-deciduous compositional continuum. Variations in structure and composition affect water quality, fish and wildlife, biodiversity, timber, and aesthetics. A retrospective approach was taken in this study in order to understand and compare the structure, pattern, and history of an...

Multiscale controls on woody riparian vegetation : distribution, diversity, and tree regeneration in four western Oregon watersheds

Creator:: Sarr, Daniel Allen
Abstract:: I studied riparian forests of four western Oregon watersheds (dry south to wet north) to determine the multiscale controls on woody riparian vegetation. I conducted separate analyses of controls on plant distribution, diversity, and tree regeneration using vegetation and environmental data collected in two related field studies: (1) a multiscale...
