A characterization of unmanaged riparian overstories in the central Oregon Coast Range

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...

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....

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...

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...

Terrestrial amphibian abundance and species richness in headwater riparian buffer strips, Oregon Coast Range

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...

Riparian litter inputs to streams in the central Oregon Coast Range

Creator:: Hart, Stephanie K.
Abstract:: Riparian zone vegetation can influence terrestrial and aquatic food webs through variations in the amounts, timing, and nutritional content of leaf and other litter inputs. Differences in vegetation composition and density, as well as riparian topography, may modulate the strength and quality of these inputs. Changes in inputs to small...

Functional relationships among vegetation, nocturnal insects, and bats in riparian areas of the Oregon Coast Range

Creator:: Ober, Holly K.
Abstract:: Vegetation provides food for many insects, and many insects serve as food for bats. We investigated the linkages among these three trophic levels in riparian areas throughout the Oregon Coast Range by examining the influence of vegetation cover, composition, and structure on the activity of nocturnal insects and bats, the...

The use of ơ15N and ơ¹³C to analyze food webs and identify source-sink relationships in riparian canopy vegetation of the Oregon Coast Range

Creator:: Scott, Emily E.
Abstract:: In the Coast Range of western Oregon, some natural resource managers are converting red alder-dominated riparian areas to conifers to increase the future source of in-stream large wood for salmonid habitat. However, studies in Alaska have shown red alder-dominated riparian areas support greater invertebrate biomass compared to conifer-dominated areas. In...

The ecology of riparian ecosystems of Northeast Oregon : shrub recovery at Meadow Creek and the structure and biomass of headwater Upper Grande Ronde ecosystems

Creator:: Case, Richard L.
Abstract:: Riparian ecosystems play numerous and essential roles related to the quality and flow of water, and food/habitat for fish, and varieties of wildlife. Due to lateral and linear linkages throughout the landscape, these zones influence the integrity of the terrestrial as well as the entire aquatic-riverine ecosystem. Since Euro-American settlement...
