Creator:: Olsen, Eldon D., Keough, David S., LaCourse, Diane K., and Oregon State University. Forest Research Laboratory
Resource Type:: Technical Report

Creator:: Olsen, Eldon D. and Oregon State University. Forest Research Laboratory
Abstract:: A compilation of Oregon State University research work on computer-aided crosscutting (bucking) of trees into logs. Major considerations for deciding whether to adopt optimal bucking and steps to implement it are described. The bulletin references field studies which evaluated and tested prototype optimal bucking systems.
Resource Type:: Technical Report

Creator:: Olsen, Eldon D. and Oregon State University. Forest Research Laboratory
Abstract:: The use of crew incentives in logging operations in the western United States is an effective way to reduce costs and provide attractive wages. However, such systems require a reliable method of setting the price, a good estimate of the daily costs of labor and equipment, and a method of...

Resource Type:: Technical Report

Creator:: Kellogg, L. D. (Loren D.), Olsen, Eldon D., and Oregon State University. Forest Research Laboratory
Abstract:: The production rates and costs of harvesting smallwood were determined for a small yarder (Koller K-300) operating under variable conditions: the size of the crew, the addition of a skidder to swing logs from the landing, and the type of harvest method-employed, either conventional or hot thinning (simultaneous felling and...

Creator:: Olsen, Eldon D., Hossain, Mohammad M., Miller, Mark E., and Oregon State University. Forest Research Laboratory
Abstract:: Work-study guidelines were developed using field data from thinning sites in the Oregon Cascade Range. Regression of detailed time study and shift-level data predicted harvesting production rates. Statistical analysis showed the relative difference in the discriminating power between shift-level studies versus detailed time studies. Indicator variables tested if there were...

Creator:: Kellogg, L. D. (Loren D.), Miller, Mark E., Olsen, Eldon D., and Oregon State University. Forest Research Laboratory
Abstract:: 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...
