Watershed response to western juniper control

Creator:: Deboodt, Timothy L.
Abstract:: Western juniper (Juniperus occidentalis) encroachment has been associated with increased soil loss and reduced infiltration resulting in the loss of native herbaceous plant communities and the bird and animal species that rely on them. Hydrologically, however, change in water yield has been linked with the amount of annual precipitation a...

Baseline stream chemistry and soil resources for the Hinkle Creek Research and Demonstration Area Project

Creator:: George, Robert Lance
Abstract:: This research addressed the opportunity to obtain baseline data for both stream chemistry and soil resources for an intensively managed forest watershed, encompassed by the North and South Forks of Hinkle Creek Watershed Research and Demonstration Area Project near Sutherlin, Oregon. A solid representative database for both stream and soil...

Down by the creek : understanding landowner perspectives on streamside health and management

Creator:: Wiskind, Adam
Abstract:: Both policy makers and private landowners have come to recognize the importance of streamside areas in the maintenance of water quality and fish habitat. Because non-industrial landowners own 42% of the streamside area in the Coast Range, their management is a significant factor in the streamside health of Western Oregon....

Forest Soils and Topography : Decoding the Influence of Physical Site Characteristics on Soil Water and Forest Productivity in Oregon's Coast Ranges

Creator:: Rodman, Henry
Abstract:: Forest soils and topography have long been known to influence forest productivity in complex terrain such as Oregon’s Coast Ranges. Incorporating physical site characteristics into predictions of forest growth and yield, however, has been problematic because of the high spatial variability of soil properties and the challenges associated with representing...

The influence of contemporary forest management on stream nutrient concentrations in an industrialized forest in the Oregon Cascades

Creator:: Meininger, William Scott
Abstract:: The increased demand for wood and fiber from a continually shrinking land base has resulted in the use of intensively managed forest plantations. The concentration of timber production on the most suitable sites allows the world's demand for forest products to be met on less land and enable native forests...

Uncertainty in forest road hydrologic modeling and catchment scale assessment offorest road sediment yield

Creator:: Surfleet, Christopher G.
Abstract:: The goal of this study was to advance methods for assessment of forest road hydrologic response and sediment yield at a catchment scale. This research looked at the effect of soil depth estimation on the Distributive Hydrology Soil Vegetation Model (DHSVM), assessed the uncertainty and accuracy of hydrologic modeling of...

Patterns in stream geomorphology and implications for hyporheic exchange flow

Creator:: Anderson, Justin K.
Abstract:: Longitudinal water surface profiles from high-gradient mountain streams provide useful indicators of the relative potential for hyporheic exchange flow in stream reaches with varying morphology. The spacing between slope breaks in step-pool and pool-riffle streams provides a geomorphic scaling metric that indicates how the length of average hyporheic flow paths...

Sediment production from forest roads in the upper Oak Creek Watershed of the Oregon Coast Range

Creator:: Amann, Joseph R.
Abstract:: Unpaved roads are sources of chronic sediment in forested watersheds. Bare soil on roads is exposed to erosion from rainfall and runoff Published research on sediment production from forest roads focuses primarily on road characteristics. Since water drives the mechanics of sediment transport, hydrologic variables should correlate with sediment production....

Forestry at the urban fringe : issues, stakeholders and conflict potential in Oregon's Soap Creek Watershed

Creator:: Edwards, Kearstin K.
Abstract:: Increasing land fragmentation, environmental regulations and neighbors' concerns pose significant challenges to forest owners at the urban fringe, whose properties are physically caught between rural landscapes and continually expanding urban centers. Using Oregon's Soap Creek Watershed as a study site, we paired qualitative and quantitative methods to identify stakeholders, their...

A physical and chemical characterization of stream water draining three Oregon Coast Range catchments

Creator:: Hale, V. Cody
Abstract:: Few studies have examined both long-term and fine-scale spatial variations in water quality of small streams in the Pacific Northwest. As such, a case study was conducted to determine if current physical and chemical properties of water in three streams located in the Oregon Coast Range differed from historically measured...
