Abstract:: Secondary plant succession and the accumulation of biomass and nutrients were documented at seven ruminant exclosures in Abies and Pseudotsuga forests variously disturbed by logging, burning, and grass seeding. Long-term (25 or more years) foraging by Rocky Mountain mule deer (Odocolleus hemionus) and Rocky Mountain elk (Genius elaphus) suppressed the...

Creator:: Weigand, James F.
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...

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...

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...

Creator:: Cole, David N., Watson, Alan E., Hall, Troy E., Spildie, David R., and Rocky Mountain Research Station (Ogden, Utah)
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...

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...

Creator:: Alexander, Robert R. and Rocky Mountain Forest and Range Experiment Station (Fort Collins, Colo.)
Abstract:: Summarizes a series of comprehensive reports on the silviculture of lodgepole pine, ponderosa pine, mixed conifer, and spruce-fir timber types. Includes what is known, what can be recommended, and what additional information is needed for each timber type. Oxford: 614. Keywords: Silviculture; forest regeneration; growth-yield; Abies lasiocarpa, A. lasiocarpa var....

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....
