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...

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...

Equations for predicting height-to-crown-base, 5-year diameter-growth rate, 5-year height-growth rate, 5-year mortality rate, and maximum size-density trajectory for Douglas-fir and western hemlock in the coastal region of the Pacific Northwest

Creator:: Hann, David W., Marshall, David D., Hanus, Mark L., and Oregon State University. Forest Research Laboratory
Abstract:: Using existing permanent research plot data, we developed equations for predicting height-to-crown-base (HCB), 5-yr diametergrowth rate (delta D), 5-yr height-growth rate (delta H), 5-yr mortality rate (PM), and the maximum size-density trajectory for Douglasfir and western hemlock in the coastal region of the Pacific Northwest. With the exception of the...

Tractor thinning productivity and costs : experience from the Willamette Young Stand Project

Creator:: Kellogg, L. D. (Loren D.), Davis, Chad T. (Chad Thomas), and Oregon State University. Forest Research Laboratory
Abstract:: Harvesting productivity rates and costs were determined for three silvicultural treatments used in commercial ground-based thinning of young stands to achieve timber management objectives and enhance wildlife habitat. Treatment definitions were based on residual trees per acre (tpa) after thinning. The treatments were light thin (115 residual tpa), light thin...

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...

An annotated bibliography of selected guides for stream habitat improvement in the Pacific Northwest

Creator:: Keim, Richard F., Price, A. Blake, Hardin, Timothy Stone, Skaugset, Arne E., Bateman, Douglas S., Gresswell, Robert E., Tesch, S. D., and Oregon State University. Forest Research Laboratory
Abstract:: This annotated bibliography is a response to widespread interest in stream habitat improvement in the Pacific Northwest by land managers, governmental and nongovernmental organizations, and the lay public. Several guides to stream habitat improvement have been written in the past, but may not be easily accessible to people from diverse...

Enhanced height-growth-rate equations for undamaged and damaged trees in southwest Oregon

Creator:: Hann, David W., Hanus, Mark L., and Oregon State University. Forest Research Laboratory
Abstract:: Equations for predicting the 5-yr height growth rate of a tree are presented for six conifer species from southwest Oregon. Equations for the combination of undamaged and damaged trees were estimated with weighted nonlinear regression techniques. These equations are being incorporated into the new southwest Oregon version of ORGANON, a...

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...

Enhanced diameter-growth-rate equations for undamaged and damaged trees in southwest Oregon

Creator:: Hann, David W., Hanus, Mark L., and Oregon State University. Forest Research Laboratory
Abstract:: Equations for predicting the 5-yr diameter-growth rate of a tree are presented for eight conifer and nine hardwood tree species from southwest Oregon. Equation parameters for undamaged and damaged trees combined were estimated by weighted nonlinear regression. The resulting equation for Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] explained more than 71%...

Practical methodology for operational layout of commercial skyline thinning systems

Creator:: Cornell, Jennie L., Kellogg, L. D. (Loren D.), and Oregon State University. Forest Research Laboratory
Abstract:: On-the-ground harvest unit layout, especially in skyline-thinning operations, is critical to meeting multiple resource objectives of the land manager and maintaining the economic viability of the timber harvesting operator. This phase of an operation can optimize the layout and harvesting of a sale or unit. Detailed layout by a knowledgeable...
