This study estimates a range of opportunity costs associated with three land
management alternatives for a site in the Oregon Coast Range. A 35,000 acre site was
selected which includes a mix of federal and private land ownership and provides
significant biological resources. The first alternative examines a plan for...
The purpose of this publication is to introduce you to the world of forest
protection by: (1) providing you with broad definitions of the five
principal groups of destructive agents; and (2) presenting some information on the impacts of these groups on the forests of Oregon.
Harvesting costs were determined for commercial thinning of young stands to
achieve vegetation and wildlife objectives. This included replicated comparisons of
thinning treatments. Treatments were defined based on residual tree stocking after
thinning. Study procedures were developed and evaluated to improve statistical
relevance. Multiple linear regression models were used to...
Logging planning and layout costs were examined for commercial thinning of 40- to 50-yr-old stands of Douglas-fir on the Willamette National Forest in the Cascade Mountains of Oregon. The study consisted of four replications of three silvicultural treatments. Thinning involved three types of logging systems: mechanized cut-to-length (a combination of...
This project was a part of larger work that compared major factors controlling patterns of carbon dynamics in two regions of the globe, the Pacific Northwest, USA and northwestern Russia. It was funded through the NASA foundation (grant # NAG5- 6242). Human economic activity is causing the release of pollutants...
Production rates and costs for skyline harvesting were examined over a range of residual thinning intensities, operational methods, and sites. The sites included three stands of 40- to 50-yr-old Douglas-fir on the Willamette National Forest in the Cascade Mountains of Oregon. Three silvicultural treatments were studied at two sites, and...
Forest recreation is one of the many non-commodity functions of forests that have
experienced a rapid growth in demand in the past few decades. Even faster growth in
demand for recreation is expected for several decades. However, such growing demand
for forest recreation is often not well perceived by owners...
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...
