Creator:: Leatherman, Louis M.
Abstract:: Co-located mills that share a log resource through a single merchandising facility are challenged with the task of allocating the costs of joint-products in order to determine log cost for each mill during a given period. While allocating joint-costs is inherently arbitrary, some allocation must be made to include raw...
Resource Type:: Capstone Project
Full Text:: Caplan for his time and for providing invaluable advice and guidance. And thank you to Scott Leavengood

Creator:: Allen, Marganne Mary
Abstract:: Soil bulk density and disturbance were measured before and after a commercial thinning of 3 0-50 year-old Douglas-fir using a cut-to-length (CTL) and a skyline system on the Willamette National Forest in the Oregon Cascades. A dual-probe nuclear densimeter was used to measure bulk density at four and eight inches....

Full Text:: in all units. Data were analyzed using paired t-tests, Tukey-Kramer multiple comparison tests

Creator:: Wilson, Robert A.
Abstract:: Time study data was collected for two horsepower classes of rubber tired skidders from field operations controlled by Associated Pulp and Paper Mills, Ltd., Tasmania, Australia. A wide range of site and logging conditions were used to produce both production per hour and cycle time predictive equations. The resultant equations...

Creator:: Litton, Sabrina
Abstract:: This study examined the effects of timber harvest and subsoiling on soil physical properties considered important to forest productivity and hydrologic concerns. Ground based mechanical timber harvesting on some soil types can cause soil disturbance including compaction. These effects in turn can influence multiple important soil physical properties that affect...
