  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.

On February 11, 1998, the U.S. Forest Service (USFS) requested that a representative of NIOSH conduct a health hazard evaluation (HHE) to evaluate and compare timber marker's (also called Forestry Technicians) exposures to a new waterborne formulation of tree marking paint developed for use by the U.S. Forestry Service. NIOSH performed several previous investigations to document Forestry Technician's exposures to alkyd enamel tree marking paint traditionally used by the USFS for timber marking operations. On May 18, 1998, two NIOSH industrial hygienists met with USFS employees and management representatives in LaGrande, Oregon, where an opening conference was conducted to discuss details of this investigation which occurred on may 19-21, 1998, at the Little Bear timber sale in the Catherine Creek Wildlife Unit located approximately 25 miles southeast of LaGrande.

  Citation × Citation Citation Abstract Copy Title: An analysis technique for testing log grades Author: O'Regan, William G., Newport, Carl A. (Carl Allen), 1925- Workable log grading systems are needed as aids to marketing timber and other phases of forest management. How can on system be evaluated and compared with other systems. The question of comparisons arose soon after the Western Pine Section of the Forest Service's National Log Grade Project was established in 1958. The analytical technique described in this report was developed as an objective, statistically sound method of evaluating log-grading systems. It has been used as the major analytical procedure in developing an advanced system for grading ponderosa pine and sugar pine saw logs in trees. Computations were done first on an IBM 701 computer. These operations demonstrated the usefulness of the technique and confirmed some anticipated limitations.

• 15. [Article] Trees, snow and flooding: an investigation of forest canopy effects on snow accumulation and melt at the plot and watershed scales in the Pacific Northwest

  Citation × Citation Citation Abstract Copy Title: Trees, snow and flooding: an investigation of forest canopy effects on snow accumulation and melt at the plot and watershed scales in the Pacific Northwest Author: Storck, Pascal Concerns about the extent to which major Pacific Northwest floods over the last decade might have been exacerbated by logging have heightened the need for a better scientific understanding of the role of forest maturity on snow accumulation and melt. To address this need, a multi-scale field and modeling study of the effects of forest canopies on snow accumulation and melt was conducted. Over a three year period, weighing lysimeters and cut-tree experiments were used to measure the process controlling snow interception and its fate at a site in the Umpqua National Forest, OR (elevation 1200 m). Continuous observations of below-canopy snowpack evolution were made over the same period. Over the study period, approximately 60 percent of annual snowfall was intercepted by the canopy (up to a maximum of 40 mm water equivalent). Approximately 72 percent and 28 percent of the intercepted snow was removed as meltwater drip and large snow masses, respectively. Apparent average sublimation rates from the intercepted snow were less than 1 mm per day and totaled approximately 100 mm per winter season.

  Citation × Citation Citation Abstract Copy Title: Fire history and pattern in a Cascade Range landscape Author: Swanson, Frederick J., Pacific Northwest Research Station (Portland, Or.), Morrison, Peter H. Fire history from years 1150 to 1985 was reconstructed by analyzing forest stands in two 1940-hectare areas in the central-western Cascade Range of Oregon. Serving as records for major fire episodes, these stands revealed a highly variable fire regime. The steeper, more dissected, lower elevation Cook-Quentin study area experienced more frequent fires (natural fire rotation = 95 years) that were commonly low to moderate in severity. The Deer study area, with its cooler, moister conditions and gentler topography, had a regime of less frequent (natural fire rotation = 149 years), predominantly stand-replacement fires. Fires created a complex mosaic of stands with variable date and severity of last burn. Fire-created forest patches originating in 1800-1900 are mostly less than 10 hectares. Since 1900, very little of the study areas burned, possibly because of fire suppression.

  Citation × Citation Citation Abstract Copy Title: Environmental effects of postfire logging: literature review and annotated bibliography Author: Pacific Northwest Research Station (Portland, Or.), Starr, Lynn, McIver, James D. The scientific literature on logging after wildfire is reviewed, with a focus on environmental effects of logging and removal of large woody structure. Rehabilitation, the practice of planting or seeding after logging, is not reviewed here. Several publications are cited that can be described as 'commentaries', intended to help frame the public debate. The authors review 21 postfire logging studies and interpret them in the context of how wildfire itself affects stands and watersheds. Results of this review are summarized in 16 major conclusions at the end of the text, most of which are based on results of no more than a handful of studies. The review is followed by an annotated bibliography and an index.

Large fallen trees in various stages of decay contribute much-needed diversity of ecological processes to terrestrial, aquatic, estuarine, coastal beach, and open ocean habitats in the Pacific Northwest. Intensive utilization and management can deprive these habitats of large fallen trees. The publication presents sound information for managers making resource management decisions on the impact of this loss on habitat diversity and on ecological processes that have an impact on long-term ecosystem productivity.

  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.
