In-forest log segregation based on acoustic measurement of wood stiffness

Creator:: Amishev, Dzhamal Y.
Abstract:: To remain competitive, the forest products industry needs to look for new and innovative processes and technologies to not only reduce costs but also to recover more value through the entire seedling-to-customer forest products supply chain. It is well recognized that measuring wood properties of logs in real time during...

Thinning aged Douglas-fir : an analysis of mobilization costs and a log bucking strategy for revenue improvement

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...

The role of strategic planning in the management of fire-prone western Oregon forests for maximizing terrestrial carbon stocks over a 100-year horizon

Creator:: Vanderberg, Michael R.
Abstract:: Current frameworks for analyzing forest carbon offset projects in disturbance-prone western forests often fail to address the dynamic nature of carbon pathways through time. They do not account for the probability of loss due to wildfire, which can influence the prediction of carbon storage at the end of a planning...

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...

The economics of carbon sequestration in western Oregon forests

Creator:: Im, Eun Ho
Abstract:: This study considered regional forest policies for sequestering carbon in existing forests in western Oregon. A model of log markets in western Oregon was employed to examine the impacts of forest policy changes on future carbon stock, harvests, and management activities. A carbon tax program, as a mitigation option for...

Balancing Timber Production and Conservation in the Oregon Coast Range: an Examination of the Response by Birds and Bird-induced Ecosystem Services to Forest Management at Multiple Scales

Creator:: Harris, Scott H.
Abstract:: Society derives many critical and irreplaceable values from forests. With a growing global human population and rates of consumption, forests are under increasing pressure to provide all these values simultaneously. To meet societal demands for wood products, tree plantations are becoming increasingly common and are replacing native forests. Yet, forests...

A comparison of the value of forest plans developed under three levels of detail regarding management intentions

Creator:: Hirte, Sarah Rebecca
Abstract:: In the field of forest planning, assumptions regarding the appropriate modeling of management behavior, translated through management prescriptions, minimum harvest ages, green-up periods, and other variables are needed if a stand-level optimization process is not used to guide the selection of stand management regimes Forest planners thus generally have a...

Forest biomass estimation with hemispherical photography for multiple forest types and various atmospheric conditions

Creator:: Clark, Joshua Andrew
Abstract:: The importance of accurately identifying inventories of domestic energy, including forest biomass, has increasingly become a priority of the US government and its citizens as the cost of fossil fuels has risen. It is useful to identify which of these resources can be processed and transported at the lowest cost...

Wood properties and use of sensor technology to improve optimal bucking and value recovery of Douglas-fir

Creator:: Acuna, Mauricio A.
Abstract:: There are a number of wood properties which affect the quality of forest products such as lumber and pulp. Of these, wood density is considered by some to be the single most important physical characteristic because it is an excellent predictor of strength, stiffness, hardness, and paper-making capacities. Accurately assessing...

Assessment of Airborne Light Detection and Ranging (LiDAR) for use in common forest engineering geomatic applications

Creator:: Craven, Michael B.
Abstract:: Airborne Light Detection and Ranging (LiDAR) has become a popular remote sensing technology to create digital terrain models and provide forest inventory information. However, little research has been done to investigate the accuracy of using airborne LiDAR to perform measurement tasks common to Forest Engineering. This thesis contains two manuscripts...

Determining optimal timber harvest and fuel treatment on a fire-threatened landscape using approximate dynamic programming

Creator:: Lauer, Christopher Joseph
Abstract:: Forest management in the face of fire risk is a challenging problem because fire spreads across a landscape and because its occurrence is unpredictable. Additionally, management must be adjusted over time as unpredictable fire events are realized. Land managers have some control over the vegetation conditions that facilitate fire spread,...

Economic modeling of tropical deforestation in Antioquia (Colombia), 1980-2000 : an analysis at a semi-fine scale with spatially explicit data

Creator:: Orrego, Sergio A.
Abstract:: This dissertation used land rent theory and an economic model of land-use conversion to examine the main drivers of the deforestation occurred in Antioquia,Colombia, between 1980 and 2000. Land-cover information at a semi-fine scale (1:25,000) obtained largely from aerial photography was employed to calculate deforestation. In addition, free international databases...

Aerial forest operations : mineral amendment project

Creator:: Cornell, Jennie L.
Abstract:: A helicopter operations problem was studied for a private forest landowner testing an experimental application of minerals on Douglas-fir (Pseudotsuga menziesil) in the Coast Range of Oregon to offset growth reductions from Swiss needle cast disease. A planning approach was needed to minimize costs for transportation and aerial application of...
