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...

Creator:: Nierenberg, Tara R.
Abstract:: Riparian areas that can be used as reference sites on which to base goals of vegetation restoration have not been documented in the Oregon Coast Range. I examined the composition and distribution of unmanaged riparian overstories in the central Oregon Coast Range along nine streams which have experienced minimal disturbance...

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...

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...

Creator:: Froyd, Cynthia A.
Abstract:: Salmonberry community structure was examined in alder-dominated riparian buffer strips in the Oregon Coast Range. Salmonberry growing on slopes was found to respond differently, to both characteristics of the buffer strips and to environmental factors, than salmonberry growing on terraces. Salmonberry, as measured by total height, number of ramets or...

Creator:: McClellan, Michael H.
Abstract:: Denitrification, the biological or chemical reduction of ionic nitrogen oxide or dinitrogen, has not been widely studied in forest ecosystems despite widespread interest in other facets of the forest nitrogen economy. This study had three main objectives: to determine whether potential for denitrification exists in forest riparian and hill slope...

Creator:: Hunter, Matthew G.
Abstract:: Most recent research on stream amphibians in the Pacific Northwest has focused on associations with reach-level or stand-level environmental features. Little is known about landscape-level distributions of these species or landscape-level aspects of their life-histories. I used a watershed-wide sample and logistic regression to develop models and maps of probability...

Creator:: Vesely, David G. (David Gordon), 1954-
Abstract:: I examined the abundance and habitat associations of terrestrial amphibian species and the species richness of terrestrial amphibian communities in riparian buffer strips, clearcuts, and unmanaged riparian forests. The study was conducted in the western hemlock (Tsuga heteropliylla) vegetation zone of the northern and central Oregon Coast Range. Data were...
