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...

Abstract:: An analysis of lumber prices provided regressions for price trends during the period 1971-95 for composite lumber grades of major timber species found in the Pacific Northwest west of the crest of the Cascade Range. The analysis included data for coastal Douglas-fir and hem-fir lumber; coastal and inland Pacific Northwest...

Abstract:: A pandora moth (Coloradia pandora Blake) outbreak began in 1991 in a ponderosa pine (Pinus ponderosa Dougl. ex. Laws) spacing study area that also included scattered sugar pine (P. lambertiana Dougl). The relation of defoliation to five tree spacings (with and without understory vegetation) was examined, and stand growth reduction...

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...

Abstract:: Six high-use destination areas were studied in the Alpine Lakes, Mount Jefferson, and Three Sisters Wildernesses in Washington and Oregon. Exit interviews were conducted with visitors, and recreation impacts and visitor encounter rates between groups were quantified. Encounter rates were extremely high and impacts were substantial but localized. Visitors were...

Abstract:: This paper provides a primer on research in the field of public involvement in natural resource decision making. Previous studies are synthesized and organized into three areas: (1 ) goals of public involvement, (2) principles related to implementing public involvement programs, and (3) evaluation of public involvement methods. A bibliography...

Creator:: Main, Marty L. and Amaranthus, Michael P.
Abstract:: Throughout the Applegate watershed, dense, overstocked, immature stands of mixed conifers and hardwoods and declining stands of mature conifers present significant and complex silvicultural problems. Stand stagnation is common, as is loss of largediameter conifers from insects and wildfire. Treatments designed to maintain or encourage development of large-diameter conifers have...

Abstract:: In September 1991, the Bureau of Land Management asked the Secretary of the Interior to convene the Endangered Species Committee. The Bureau wanted permission to proceed with 44 timber sales In Oregon that the U.S. Fish and Wildlife Service had ruled would jeopardize the continued existence of the northern spotted...

Abstract:: Recently released national forest plans and conservation plans for the protection of the northern spotted owl all call for a change in management direction on public forest lands in Oregon. The result will be a substantial reduction in public timber harvests in the state. This report summarizes how the conservation...

Abstract:: Equations for predicting individual-tree height growth per 5-year period are presented for Douglas-fir, white fir, grand fir, ponderosa pine, sugar pine, and incense-cedar growing in the mixed-conifer zone of southwest Oregon. The data used to develop the equations came from 3,648 trees sampled from 391 stands in the study area....
