Statistical comparison of methods used in harvesting work studies

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...

Production and costs of cut-to-length thinning : experience from the Willamette Young Stand Project

Creator:

Kellogg, L. D. (Loren D.), Spong, Ben, and Oregon State University. Forest Research Laboratory

Abstract:

Young Douglas-fir stands were commercially thinned to achieve vegetation- and wildlife-related objectives. Harvesting and forwarding production and costs were compared among three mechanized thinning treatments: light thin [(115 residual trees per acre (tpa)], light thin with 0.5-ac openings (92 residual tpa), and heavy thin (53 residual tpa). The sites were...
