Creator:: LeDoux, Chris B.
Abstract:: Strip thinning is recognized as a way of commercial thinning young-growth stands. strip thinning has been used worldwide. The purpose of this study was to explicitly evaluate the costs and benefits associated with skyline strip thinning in young Douglas-fir (Pseudotuqo menzesii Franco) stands in the Pacific Northwest and to compare...

Creator:: Chung, Woodam
Abstract:: Designing timber harvesting units is a challenging task. The task requires decision making on logging equipment, landing site, cable road profile, road location, and transportation system. Traditionally forest planners have done the task manually. However, the manual method makes it difficult to examine many alternatives and the harvest plans depend...

Creator:: Kelly, Sharon
Abstract:: New types of exchange arrangements are becoming increasingly popular for a wide range of goods traded internationally. Several types of countertrade arrangements have been identified, ranging from pure barter to more elaborate schemes where only a portion of the trade is "paid for" in goods, including bilateral trading agreements with...

Creator:: Pilkerton, Stephen J.
Abstract:: Contract harvest operations have become the preferred approach to reducing the largest cost component of timber production through free market competition amongst logging contractors bidding or negotiating for work. The goal of this research was to investigate economic components of harvesting operations not previously studied for steep slope thinning harvests...

Creator:: Duan, Jinfan
Abstract:: This work describes the modeling framework and initial results for CLAWS (Coupled Landscape And Water System), a physically-based, spatially-distributed hydrologicgeomorphic model that has been coupled with a vegetation dynamics simulation. Spatial variability of topography, soil, vegetation, and climate drive a hydrology module that calculates the water budget at given time...

Creator:: Riyadi, Dedi M. M. (Dedi M. Masykur)
Abstract:: Objective of this study was to compare accuracy of several travel cost methods, by employing Monte Carlo simulations in the single site framework. Estimates from five methods were compared to the "true" travel cost coefficient and "true" consumer surplus. Each method was ranked, using the root mean squared error (RMSE)...

Creator:: Zégre, Nicolas P.
Abstract:: This dissertation is a collection of three manuscripts that serve to fill the knowledge gaps and advance methods of detecting the effects of contemporary forest harvesting in experimental catchment studies. While there is a preponderance of studies evaluating the environmental effects of forest harvesting in the western United States, few...
