An econometric analysis of timber demand and supply relationships on the Siuslaw National Forest

Creator:: Shih, Kung
Abstract:: To abstract the fundamental market structures of stumpage sold from the Siuslaw National Forest, a three-equation structural model with different assumptions on private cut was empirically derived. Under the private cut price-fixed assumption, the structural model can be simplified as a single-equation model with stumpage price as dependent variable and...

Assessing the Potential for a Late Pleistocene-Early Holocene Occupation at the Tahkenitch Landing Site (35DO130), Siuslaw National Forest, Oregon Dunes National Recreation Area

Creator:: Kirkpatrick, Molly C.
Abstract:: The archaeological record of the First Americans is known almost exclusively from interior sites located away from coastal margins. While archaeologists hypothesize that early peoples initially migrated into the Americas along the Pacific coast, environmental changes associated with postglacial sea level rise may have destroyed or obscured such early sites....

Effects of burrowing by mountain beaver (Aplodontia rufa) on soil in a young forest in the Oregon Coast Range

Creator:: Russell, William Ogburn, 1964-
Abstract:: Soil effects from mountain beaver (Aplodontia rufa ) burrowing were investigated in Oregon Coast Range soils formed from Tyee sandstone. The potential for observed changes in soil to affect productivity was assessed. Soil horizons from mountain beaver mound soil and adjacent unmounded profiles were collected with a monolith-type quantitative sampler....

Where the Stream Meets the Road : Prioritizing Culvert Replacement for Fish Passage

Creator:: Reagan, Rachel E.
Abstract:: Streams across the world are highly fragmented due to the presence of in-stream barriers (e.g., dams and stream-road crossings), many of which restrict or block fish passage. Retrofitting or replacing these structures is a high priority for restoring habitat connectivity for native fishes and other aquatic organisms in the Pacific...

A Methodology to directly input data from an uncontrolled aerial photograph into a vector based geographic information system

Creator:: Sneed, Jacquelin M.
Abstract:: Historically the U.S. Forest Service has used uncorrected aerial photographs to delineate proposed and past management activities on the land base it manages. Transferring a boundary from an image not planimetrically correct to a planimetrically corrected image introduces errors. Positional accuracy of boundaries affects the number of acres the Forest...

Seasonal variations in tidal dynamics, water quality and sediments in the Siuslaw Estuary

Creator:: Utt, Michael Ernest
Abstract:: Seasonal data on tides, water quality and sediments in the Siuslaw Estuary were collected. Tide and velocity data were analyzed to evaluate damping conditions in the estuary. The system was found to approximate a weakly damped standing wave. A strong relationship of damping conditions to river flow was observed. The...

The effects of forage improvement practices on Roosevelt elk in the Oregon Coast Range

Creator:: Stussy, Rosemary J.
Abstract:: Forage availability, diets, distribution, and productivity were compared for Roosevelt elk, Cervus elaphus roosevelti, using improved (i.e. seeded, fertilized, and grazed) and untreated areas of the Oregon Coast Range. Seasonal forage availability was substantially different on 1-year-old improved and untreated clearcuts, but the differences diminished by clearcut age 4 and...

An economic evaluation of logging road maintenance

Creator:: Feeney, Daniel John
Abstract:: This thesis describes the results of a project conducted to determine the economics of forest road maintenance alternatives between periods of timber harvesting. An open road and a closed road alternative will be compared to the economics of clearcutting an entire area and obliterating the road system until reentry at...

One-dimensional numerical model test and predictions for the Siuslaw Estuary

Creator:: Farreras, Salvador F.
Abstract:: The one-dimensional numerical model developed by Carl R. Goodwin is applied to the Siuslaw estuary. Vertical displacement, horizontal velocity and flow of the water as a function of time and distance from the mouth given by the model are compared with field observations taken under different water mixing conditions in...
