An investigation of factors affecting the optimal output log distribution from mechanical harvesting and processing systems

Creator:: Marshall, Hamish Douglas
Abstract:: Globally the forest harvesting industry is becoming increasingly mechanized. Driving this trend is the desire to increase productivity and reduce cost, as well as to improve labor-related issues. With mechanization comes an in-forest platform for the introduction of state-of-the-art communication and measurement technologies, and powerful on-board computers. These systems have...

Economic optimization of forest biomass processing and transport

Creator:: Zamora Cristales, René Arturo
Abstract:: An economic analysis and optimization of forest biomass processing and transportation at the operational level is presented. Renewable sources of energy have captured the interest of public and private institutions to develop cost-effective supply chains to reduce dependence on fossil fuels. The production of energy from forest harvest residues constitutes...

A simulation of the comparative costs and benefits of skyline strip thinning

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...

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...

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...

Estimating volume and value on standing timber in hybrid poplar plantations using terrestrial laser scanning : a case study

Creator:: Barnett, Jennifer S.
Abstract:: Terrestrial laser scanning (TLS) may provide a way to increase timber value recovery by replacing manual timber cruising with a simple-to-use, cost-effective alternative. TLS has been studied in several trials worldwide. Past studies have not compared TLS based estimates with mill estimates of stem value and volume. Three differently stocked...

Contemporary forest road management with economic and environmental objectives

Creator:: Thompson, Matthew P.
Abstract:: One of the basic questions facing transportation planners and road managers is how to provide and maintain a road system that provides efficient access to the forest while limiting adverse effects roads can have on water and soil resources. The purpose of this study is to develop decision support models...

Thinning with prescribed fire and timber harvesting mechanization for fuels reduction and forest restoration

Creator:: Matzka, Peter J.
Abstract:: In the Blue Mountains of northeastern Oregon, prescribed fire and mechanical harvesting economics were investigated for fuels reduction and forest restoration. Using a cut-to-length harvesting system, three single-grip harvesters and three forwarders produced significantly different production rates. For the harvesters, significant variables that affected production rates were found to be:...

An integrated study of mechanical forest fuel reduction: quantifying multiple factors at the stand level

Creator:: Bolding, Michael Chad, 1977-
Abstract:: Recent catastrophic wildfires have forced the forest management community to develop new strategies for reducing forest fuels. Tightly spaced understory trees often create a fire ladder allowing surface fires to encroach into the crowns of overstory trees. This situation can lead to intensive, catastrophic, stand-replacement forest fires. Mechanical removal or...
