Composition, volume, and prices for major softwood lumber types in western Oregon and Washington, 1971-2020

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...

Technical Report
Growth and yield of western larch under controlled levels of stocking in the Blue Mountains of Oregon

Creator:

Cochran, P.H.

Abstract:

Repeated thinning to five growing-stock levels resulted in widely differing tree sizes and volumes per acre after 30 years. Largest trees but the least cubic-volume yield per acre were produced in the heaviest thinning level, whereas highest board-foot yields were found in intermediate thinning levels. partial defoliation by larch casebearer...

Lodgepole pine development after early spacing in the Blue Mountains of Oregon

Creator:

Cochran, P.H. and Dahms, Walter G.

Abstract:

Seedlings were thinned to spacings of 5, 9, 12, 15, and 18 feet and measured periodically. Twenty-seven years after treatment, quadratic mean diameters increased curvilinearity (p < or = 0.05) as spacing increased, but total height did not differ significantly (p < or = 0.05) with spacing. Corresponding basal areas...

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...

Stereo photo series for quantifying forest residues in coastal Oregon forests: second-growth Douglas-fir--western hemlock type, western hemlock--Sitka spruce type, and red alder type

Creator:

Ottmar, Roger D. and Hardy, Colin C.

Abstract:

A series of stereo photographs displays a range of residue loadings for cleancut units in three general forest types common to coastal Oregon forest lands: Douglas-fir--western hemlock (second-growth), western hemlock--Sitka spruce, and red alder. Postburn residue levels are also represented for the Douglas-fir--western hemlock, and red alder types. Information with...

Invertebrates of the H. J. Andrews Experimental Forest, western Cascade Mountains, Oregon. IV, the oribatid mites (Acari: Cryptostigmata)

Creator:

Moldenke, Andrew R., Fichter, Becky L., Pacific Northwest Research Station (Portland, Or.), and H.J. Andrews Experimental Forest (Or.)

Abstract:

A fully illustrated key is presented for identifying genera of oribatid mites known from or suspected of occurring in the Pacific Northwest. The manual includes an introduction detailing sampling methodology; an illustrated glossary of all terminology used; two color plates of all taxa from the H.J. Andrews Experimental Forest; a...

Modification of Mixed-Conifer Forests by Ruminant Herbivores in the Blue Mountains Ecological Province

Creator:

Riggs, Robert A., Tiedemann, Arthur R., Cook, John G., Ballard, Teena M., Edgerton, Paul J., Vavra, Martin, Krueger, William C., Hall, Frederick C., Bryant, Larry D., Irwin, Larry L., and Delcurto, Timothy

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...

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...

Starkey Project : history facilities, and data collection methods for ungulate research

Creator:

Rowland, Mary M., Bryant, Larry D., Johnson, Bruce K., Noyes, James H., Wisdom, Michael J., and Thomas, Jack Ward

Abstract:

In the 1980s, resource managers were increasingly concerned about effects of timber harvest on ungulates in National Forests. Land and resource management plans incorporated restrictions on timber harvest to maintain cover for Rocky Mountain elk (CeNus e/aphus ne/soni V. Bailey) and mule deer (Odocoileus hemionus hemionus RafinesqueJ, and habitat models...

Reducing stand densities in immature and mature stands, Applegate Watershed, Southwest Oregon

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...
