Comparative effects of precommercial thinning, urea fertilizer, and red alder in a site 11, coast Douglas-fir plantation

Creator:: Miller, Richard E., Obermeyer, Edmund L., and Anderson, Harry William
Abstract:: The authors varied the number of red alder retained with 300 Douglas-fir per acre on a high-quality site in coastal Oregon. Alder densities of 0, 20, 40, and 80 per acre were tested. The authors' fifth treatment eliminated nitrogen-fixing alder, but substantial nitrogen fertilizer. Treatment 6 had neither thinning nor...

The effects of dietary algal and lipid supplements on the gonadal and larval development of Crassostrea gigas kumamoto (Thunberg)

Creator:: Robinson, Anja M.
Abstract:: Under laboratory conditions, elevated temperatures accelerated production of gametes. However, when conditioning for spawning at elevated temperatures was initiated early in the season (January-March), larval survival and number of spat collected were significantly lower than when conditioning was initiated in may or June. At elevated temperatures, broodstock oysters were fed...

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...

The Role of Natural Resources Information in Oregon Legislative Policy-Making; Two Case Studies from the 1991 Legislative Session

Creator:: Brown, Mara Arwyn
Abstract:: This paper focuses on the role of natural resources information in Oregon legislative policy-making, based on the two legislative case studies from the 1991 Legislative Session, surveys conducted of state natural resource agency legislative liaisons, and a review of current literature addressing policy-making and the role of science in policy-making....

Post-eruption recovery and secondary production of grazing insects in two streams near Mt. St. Helens

Creator:: Meyerhoff, Richard Dietrich
Abstract:: The eruption of Mt. St. Helens provided the opportunity to study secondary production of grazing insects in the context of disturbance. Two stream sites were chosen that significantly differed in how their watersheds were impacted by the eruption. Clearwater Creek was catastrophically disturbed (physical alteration of habitat, loss of riparian...

Asymptotic height-diameter equations for twenty-four tree species in western Oregon

Creator:: Garman, Steven L. (Steven Lee), 1955-, Acker, Steven A., Ohmann, Janet L., Spies, Thomas A. (Thomas Allen), and Oregon State University. Forest Research Laboratory
Abstract:: Equations for predicting height from diameter outside bark at breast height (DBH) were generated for 24 tree species in western Oregon. The equations were based on the asymptotic Chapman-Richards function. Because geographic location and site productivity may influence height-diameter relationships, height-diameter measures from 8727 plots were first grouped by site...

The willingness of Central Oregon irrigators to donate water rights to augment Deschutes River flow

Creator:: Barkley, David, 1972-
Abstract:: This study used contingent valuation techniques to estimate the willingness of central Oregon Irrigators to donate a portion of their water rights to increase Deschutes River flow. This study was different from previous contingent valuation studies in that it used water rights as the payment vehicles instead of dollars -...

Pilot experiment of forest fertilization during an outbreak of the western spruce budworm in Northeastern Oregon

Creator:: Mason, Richard R., Wickman, B. E., Paul, H. G., and Torgersen, T. R.
Abstract:: Mixed-conifer stands of grand fir (Abies grandis (Dougl. ex D. Don) Lindl., Douglas-fir (Pseudotsuga menziesii var. glauca (Beissn.) Franco), and ponderosa pine (Pinus ponderosa Dougl. ex Laws.) were fertilized with nitrogen and combination treatments of nitrogen, phosphorus, potassium, and sulfur to test their effects on trees and associated insects during...

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...
