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...

Service life of treated and untreated fence posts : 1996 post farm report

Creator:: Morrell, Jeffrey J., Miller, Donald James, Schneider, Philip F., and Oregon State University. Forest Research Laboratory
Abstract:: Untreated and preservative-treated fence posts were exposed in soil at a test site near Corvallis, OR. Several species, including western juniper and Osage-orange, showed exceptional natural durability. Preservative treatment generally extended the useful life of the posts, but the degree of protection varied with the chemical and the application method.

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...

Natural durability of wood : a worldwide checklist of species

Creator:: Scheffer, T. C., Morrell, Jeffrey J., and Oregon State University. Forest Research Laboratory
Abstract:: Naturally durable woods have a variety of commercial uses. Natural resistance to decay has been evaluated in field and laboratory tests of wood from many species, but there are few places where commercial wood users can find comparative assessments of natural durability. In this report, previous studies have been used...

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...

Extending southwest Oregon's Douglas-fir dominant height growth equation to older ages

Creator:: Hann, David W. and Oregon State University. Forest Research Laboratory
Abstract:: Hann and Scrivani (1987) developed dominant height growth equations for Douglas- fir in southwest Oregon using stem analysis data sets with an upper age of approximately 125 years at breast height. The objective of this study was to determine whether these equations could be extrapolated for ages of 250 years...

Regenerating coastal forests in Oregon : an annotated bibliography of selected ecological literature

Creator:: Loucks, Donna M., Knowe, Steven A. (Steven Alan), 1954-, Shainsky, Lauri J., Pancheco, Alex A., and Oregon State University. Forest Research Laboratory
Abstract:: This annotated bibliography was compiled to provide a comprehensive list of sources on the ecological factors that affect forest regeneration. Abstracts from 494 publications are indexed by author, species, and subject, and are arranged into 4 major sections. Topics include the effects of biotic factors, abiotic factors, and stand and...

Survival and growth of Douglas-fir seed sources in the Hospital Tract rangewide source archive plantation

Creator:: Gamble, William E., Adams, W. T., Tappeiner, J. C. (John C.), and Oregon State University. Forest Research Laboratory
Abstract:: "In 1954, Dr. Helge Irgens-Moller initiated a rangewide collection of seed and seedlings of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco). Nearly 700 trees or stands were sampled in 10 western states, Canada, and Mexico. From 1957 to 1971, 639 of these collections were planted in the Hospital Tract Rangewide Source Archive...
