A Multi-Spatial Scale Economic Analysis of the Impacts of Bear Damage to Douglas-fir on Private Timberlands in the Pacific Northwest

Creator:: Kline, Kristina N.
Abstract:: Black bears (Ursus americanus) in western Oregon and Washington peel bark from conifers in early spring to forage on the sugar-rich phloem and cambial tissues. This provides important energy at a time when similarly attractive forage is scarce. Bears often damage Douglas-fir (Pseudotsuga menziesii) trees in stands that are intensively...

An analysis of technical efficiency and productivity growth in the Pacific Northwest sawmill industry

Creator:: Helvoigt, Ted L.
Abstract:: The objective of this project was to investigate technical efficiency and productivity growth in the Pacific Northwest sawmilling industry over the period 1968-2002. Productivity growth was decomposed into three components: technical change, efficiency change, and scale efficiency change. In addition, using econometric methods, changes in output elasticities and input substitution...

Biochemical conversion of lignocellulosic biomass to ethanol : experimental, enzymatic hydrolysis modeling, techno-economic and life cycle assessment studies

Creator:: Kumar, Deepak
Abstract:: Ethanol production from lignocellulosic feedstock has been under intense scrutiny as a transportation fuel due to its potential to address concerns of increasing energy consumption, limited fossil energy resources, climate changes due to greenhouse gas emissions from fossil fuels, and especially use of non-food biomaterials, which address the biggest limitation...

Cost-efficient management of aquatic invasive species : application to New Zealand mudsnails in the Pacific Northwest

Creator:: Lim, Youngah
Abstract:: By affecting the ecological, pecuniary and aesthetic productivity of ecosystems, invasive species (IS) increase production and management costs to business, while straining public agencies' budgets with monitoring, enforcement and management efforts. Understanding invasion pathways or vectors, and identifying costs and benefits of alternative management strategies are critical to public and...

Exploration of statistical methods for synthesizing the effects of variable-retention harvesting on multiple taxa

Creator:: Lam, Tzeng Yih
Abstract:: Variable-retention harvesting was proposed to reduce loss of biodiversity and ecosystem processes associated with late-seral Douglas-fir (Pseudotsuga menziesii) forests in the Pacific Northwest. The Demonstration of Ecosystem Management Options experiment was established to test this hypothesis. Analysis presents various challenges to drawing statistical inferences about treatment effects. This dissertation explored...

Forest Harvest Residue Moisture Management in the Pacific Northwest, USA

Creator:: Belart Lengerich, Maria Francisca
Abstract:: Moisture content management is a key requirement to improve forest harvest residue economics for bioenergy production. This dissertation aims to contribute towards better management through these three general objectives (1) Determine average moisture content of fresh forest harvest residues and its changes over the different seasons of the year, focusing...

Net farm income and the role of water development projects

Creator:: Anderson, William J.
Abstract:: The recent 2013 Oregon State Board of Agriculture report identified several ways to improve agricultural income in Oregon. Recommendations to improve water development are at the top of the report's list of objectives. In this study, I analyze the relationship between net cash farm income (NCFI) and a cross-sectional set...

Pacific Northwest rangeland carbon sequestration

Creator:: Wiggins, Seth T.
Abstract:: This paper models the supply curve of carbon sequestration on Pacific Northwest rangelands. Rangeland managers have the ability to sequester carbon in agricultural soils by implementing alternative management practices on their farms. Their low adoption rate in practice suggests a high opportunity cost associated with their implementation. To increase their...

Response of Soil Microbially Mediated Nutrient Cycling and Community Structure to Timber Harvest in the Pacific Northwest

Creator:: Danielson, Rachel E.
Abstract:: Forest harvest persists as one of the most globally important industries, and crucially provides raw wood products for both building and fuel materials. Mechanistically complex abiotic and biotic processes curb ecosystem recovery following timber harvest and it is of great importance to understand the effects of this practice on biogeochemical...

The effects of increased supply and emerging technologies in the forest products industry on rural communities in the northwest U.S.

Creator:: Crandall, Mindy S.
Abstract:: The development of a market for currently non-merchantable forest material, such as harvest residues of tops and limbs of trees or small diameter trees, has been suggested as a possible win-win solution that could: (i) provide a financial incentive to help motivate treatments to reduce wildfire risk or restore forest...
