This was the first year that extensive monitoring of forest vegetation for ozone injury was carried out in Oregon, and Washington. Injury was detected on ponderosa and Jeffrey pine in the Sierra Nevada permanent plots and on red elderberry at one FHM location in southwest Washington. No injury was detected at the Mount Rainier sites. The authors also report on results of a trial where red alder, huckleberry, blue elderberry, and chokecherry were exposed to ozone under controlled conditions.

  Citation × Citation Citation Abstract Copy Title: Watershed restoration, jobs-in-the-woods, and community assistance : Redwood National Park and the Northwest Forest Plan Author: DeForest, Christopher E., Pacific Northwest Research Station (Portland, Or.) There are many parallels between the 1978 legislation to expand Redwood National Park and the Northwest Forest Plan, which together with the Northwest Economic Adjustment Initiative formed the 1993 Pacific Northwest Initiative. In both situations, the Federal Government sought to promote retraining for displaced workers, to undertake watershed assessment and restoration work, and to assist communities with economic planning, grants, and transitions. Both of these efforts point out the inherent conflicts between the economic and ecological objectives of watershed restoration. No one wants to have to choose between reducing sediment an reducing unemployment in coastal forests.

  Citation × Citation Citation Abstract Copy Title: Management experiments for high-elevation agroforestry systems jointly producing matsutake mushrooms and high-quality timber in the Cascade Range of southern Oregon Author: Weigand, James F. Experimental prescriptions compare agroforestry systems designed to increase financial returns from high-elevation stands in the southern Oregon Cascade Range. The prescriptions emphasize alternative approaches for joint production of North American matsutake mushrooms (also known as North American pine mushrooms; Tricholoma magnivelare) and high-quality timber. Other agroforestry byproducts from the system are ornamental conifer boughs, pine cones, and Christmas trees. Management practices concentrate on increasing the physiological efficiency and vigor of trees, and on altering leaf area index, tree species composition, and stand age-class structure to increase matsutake reproduction. Programs of thinning and branch pruning test regulating flows of energy and moisture to mushroom mycelia in the upper soil. Experimental prescriptions incorporate monitoring to evaluate ecosystem responses to management and to accelerate adaptive learning.

• 5. [Article] Growth and yield of western larch under controlled levels of stocking in the Blue Mountains of Oregon

  Citation × Citation Citation Abstract Copy Title: Growth and yield of western larch under controlled levels of stocking in the Blue Mountains of Oregon Author: Cochran, P.H. 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 (Coleophora Iaricella Hubner), drought, and top damage from ice occurred, and site trees grew less in height than expected during the 30-year study. Curvilinear increases in periodic annual increments of both basal area and cubic volume generally occurred with increasing stand density, but increments dropped off at the highest stand densities for some periods. Anticipated patterns for these increments were found after fitting a model that included stand density index, height increments of site trees, and dummy variables for periods as independent variables. heavy thinning did not increase the age of culmination of cubic-volume means annual increment as expected. Thinning stands of larch to densities as low as 50 percent of 'normal' results in little loss of basal-area growth, a moderate loss in volume production, and a large increase in tree diameter. Thinning is necessary in many larch stands to maintain vigorous, rapidly growing trees.

  Citation × Citation Citation Abstract Copy Title: Reduction in growth of pole-sized Ponderosa pine related to a Pandora moth outbreak in central Oregon Author: Pacific Northwest Research Station (Portland, Or.), Cochran, P.H. 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 due to defoliation was estimated. Defoliation generally increased as spacing varied from 2 to 5.7 meters and then decreased as spacing increased to 8 meters. Partial defoliation in 1992 reduced stand volume growth, while partial defoliation in 1994 reduced height growth during 1990-94. Basal area growth of nonefoliated sugar pine and partially defoliated ponderosa pine trees outside the outbreak area. Ratios of annual basal area increments for nondefoliated trees to annual increments of partially defoliated ponderosa pine sharply increased after the outbreak. Basal area annual increments of sample trees were reduced by 25 prcent in the first growing season after defoliation (1992), 30 percent the second year after defoliation (1993), and 63 percent after the second defoliation (1994).

  Citation × Citation Citation Abstract Copy Title: Reducing stand densities in immature and mature stands, Applegate Watershed, Southwest Oregon Author: Amaranthus, Michael P., Pacific Northwest Research Station (Portland, Or.), Main, Marty L. In the study the authors examined conditions following density management treatments in two adjacent but dissimilar stands in Applegate Watershed, Oregon. An immature stand received a unique density reduction treatment retaining both hardwoods and conifers to encourage long-term survival and growth of its coniferous component. The mature stand density reduction treatment focused on removal of the competitive influence from overstocked, surpressed understory trees and maintaining existing large-diameter conifers. Precommercial thinning greatly reduced stand density and increased quadratic mean diameters in the immature stand. In the immature stand the combination of commercial and precommercial thinnings produced a reduced stand density designed to improve overall stand vigor.

The Northwest economic adjustment initiative (NWEAI) provides economic assistance to a region including western Washington, western Oregon, and northern California. Timber harvests have fallen markedly in this region since 1990. The forest products industry is the largest manufacturing sector in the region, and employment has followed the downward trend in timber harvest. There are important differences in the declines in timber harvest, employment, and the importance of the forest products industry at the county level. The NWEAI is a significant initiative designed to coordinate and manage Federal economic assistance efforts in the region.

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 ponderosa, sugar, and western white pines; and inland Pacific Northwest and Rocky Mountain lodgepole pine. Future prices of grades by species group are based on these price trends and the latest average regional lumber values established in the Timber Assessment Market Model (TAMM). Land managers can use the price projections in financial analyses of management practices that are designed to affect the quality of timber resources.
