Skyline thinning production and costs : experience from the Willamette Young Stand Project

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...

Contributions to Collaborative Filtering Research

Creator:: Nong, Shuzhen
Abstract:: In this report, I first introduce three areas of interest to collaborative filtering researchers, namely: (a) how to solve the sparsity and scalability problems in recommendation systems; (b) how to rapidly develop and test collaborative filtering algorithms; and (c) how to apply collaborative filtering to unbounded numeric preference data. In...

College of Forestry Integrated Research Project : ecological and socioeconomic responses to alternative silvicultural treatments

Creator:: Maguire, Chris C., Chambers, Carol L., and Oregon State University. Forest Research Laboratory
Abstract:: The College of Forestry Integrated Research Project (CFIRP) is an on-going experiment in the eastern Coast Range foothills of western Oregon. Started in 1989, a team of scientists, resource managers, and students at Oregon State University designed and implemented silvicultural alternatives to clearcutting. These silvicultural practices aimed to create and...

Characterizing PM2.5 with Different Source Contributions

Creator:: Perez, Allison Mae S.
Abstract:: Ubiquitous fine particulate matter (PM2.5) exposures significantly impact global public health, yet little is known about the mechanisms causing these known adverse health effects. Oxidative stress due to PM2.5 associated chemical constituents, such as polycyclic aromatic hydrocarbons (PAHs), is a proposed possible mechanism for PM2.5 mediated health effects. Variations in...

Silviculture and Swiss needle cast : research and recommendations

Creator:: Filip, Gregory M., Kanaskie, Alan, Kavanagh, Kathleen L., 1955-, Johnson, Greg, Johnson, Randy (G. Randy), Maguire, Douglas A. (Douglas Alan), and Oregon State University. Forest Research Laboratory
Abstract:: For the past ten years, Douglas-fir on the Oregon and Washington coast has shown a progressive decrease in height and diameter increment as a result of Swiss needle cast, which is caused by Phaeocryptopus gaeumannii. In this contribution, we discuss the effects of silvicultural operations on Swiss needle cast and...

Maximizing efficiency of forest herbicides in the Sierra Nevada and Oregon : research background and user guide

Creator:: Fredrickson, Edward and Newton, Michael, 1932-
Abstract:: This paper comprises two major sections. In the first, tests of the influence of several application factors on efficiency of silvicultural herbicides are described for evergreen shrub, deciduous shrub, and herbaceous forest vegetation in Oregon and California. The second presents decision trees illustrating how to use the experimental results and...

Wood pole maintenance manual

Creator:: Morrell, Jeffrey J. and Oregon State University. Forest Research Laboratory
Abstract:: The specification, inspection, and remedial treatment of utility poles are addressed. Included are discussions of enhancing specifications for improved performance, techniques for detecting decay and other defects, and chemical treatments available for arresting decay of poles in service.

Poplar chip production for Willamette Valley grass seed sites

Creator:: Withrow-Robinson, Bradford A., Hibbs, David E., Beuter, John H., and Oregon State University. Forest Research Laboratory
Abstract:: This publication is part of a 1-year project funded by the Oregon Department of Agriculture, Alternatives to Field Burning Program. Crop substitution is one strategy for reducing smoke from field burning. The objective of the project was to evaluate the potential for hybrid poplar as an alternative crop for poorly...

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...

Reanalysis of the SMC-ORGANON equations for diameter-growth rate, height-growth rate, and mortality rate of Douglas-fir

Creator:: Hann, David W., Marshall, David D., Hanus, Mark L., and Oregon State University. Forest Research Laboratory
Abstract:: Using existing data from untreated research plots, we developed equations for predicting 5-yr diameter-growth rate (ΔD₅), 5-yr height-growth rate (ΔH₅), and 5-yr mortality rate (PM₅) for Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] in the coastal region of the Pacific Northwest. These equations are revisions of the equations constructed in 1995–1997 for...
