Environment and shoot growth of woody plants

Creator:: Lavender, Denis P. and Oregon State University. Forest Research Laboratory
Abstract:: Perennial woody plants have a complex annual cycle keyed to the environment. Temperate plants have an annual dormant period commonly broken by exposure to low temperatures, although daily photoperiods of 16 hours or longer may partially substitute for the chilling. Shoot growth in the spring is normally stimulated by rising...

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...

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...

Forest Service Special Agent in Charge Report: Nationwide Study

Creator:: Chavez, Deborah J. and Tynon, Joanne F.
Abstract:: This study is the second in a series of studies to evaluate perceptions of USDA Forest Service law enforcement personnel of the roles, responsibilities, and issues entailed in their jobs. An e-mail survey was administered to the nine Forest Ser-vice special agents in charge (SACs) across the United States. All...

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...

Logging planning and layout costs for thinning : experience from the Willamette Young Stand Project

Creator:: Kellogg, L. D. (Loren D.), Milota, Ginger, Stringham, Bennett, and Oregon State University. Forest Research Laboratory
Abstract:: Logging planning and layout costs were examined for commercial thinning of 40- to 50-yr-old stands of Douglas-fir on the Willamette National Forest in the Cascade Mountains of Oregon. The study consisted of four replications of three silvicultural treatments. Thinning involved three types of logging systems: mechanized cut-to-length (a combination of...
