es Woody biomass for bioenergy and biofuels in the United States—a briefing paper. By www.fs.fed.us Published On :: Mon, 09 Aug 2010 11:10:00 PST Woody biomass can be used for the generation of heat, electricity, and biofuels. In many cases, the technology for converting woody biomass into energy has been established for decades, but because the price of woody biomass energy has not been competitive with traditional fossil fuels, bioenergy production from woody biomass has not been widely adopted. However, current projections of future energy use and renewable energy and climate change legislation under consideration suggest increased use of both forest and agriculture biomass energy in the coming decades.

Portland, OR: U.S Department of Agriculture, Forest Service,Pacific Northwest Research Station. 80 p. By www.fs.fed.us Published On :: Thu., 25 Oct 2012 13:30:00 PST Forest managers are seeking practical guidance on how to adapt their current practices and, if necessary, their management goals, in response to climate change. Science-management collaboration was initiated on national forests in eastern Washington where resource managers showed a keen interest in science-based options for adapting to climate change at a 2-day workshop. Scientists and managers reviewed current climate change science and identified resources vulnerable to expected climate change. Vulnerabilities related to vegetation and habitat management included potential reductions in forest biodiversity and low forest resilience to changing disturbance regimes. The vulnerabilities related to aquatic and infrastructure resources included changing water quality and quantity, the risk to roads and other facilities from changes to hydrologic regimes, and the potential loss of at-risk aquatic species and habitats. Managers then worked in facilitated groups to identify adaptations that could be implemented through management and planning to reduce the vulnerability of key resources to climate change. The identified adaptations were grouped under two major headings: Increasing Ecological Resiliency to Climate Change, and Increasing Social and Economic Resiliency to Climate Change. The information generated from the science-management collaborative represents an initial and important step in identifying and prioritizing tangible steps to address climate change in forest management. Next would be the development of detailed implementation strategies that address the identified management adaptations.. Full Article

es Domestic Market Opportunities For Alaska Lumber-Species Preferences By Secondary Wood Products Manufacturers In The Continental United States. By www.fs.fed.us Published On :: Wed, 05 Apr 2006 15:25:36 PST New equipment, technology, and marketing efforts have allowed Alaska's wood products producers to consider opportunities previously unavailable to them. Until recently, the primary product produced by Alaska firms was rough, unseasoned lumber sold primarily within local markets. Given the purchase and installation of new drying and planing equipment, Alaska producers can now enter domestic and export markets for a variety of secondary wood products. Previously underutilized species, such as red alder (Alnus rubra Bong.), paper birch (Betula papyrifera Marsh.), and Alaska yellow-cedar (Chamaecyparis nootkatensis (D. Don) Spach) are also gaining in popularity and market potential. A detailed knowledge of species preferences for Alaska lumber, across business types and geographic regions, will be essential if Alaska producers are to be competitive. Full Article
es The Pacific Northwest Research Station's Biodiversity Initiative: Collaborating For Biodiversity Management By www.fs.fed.us Published On :: Wed, 05 Apr 2006 15:25:36 PST The Pacific Northwest Research Station launched a Biodiversity Initiative to assist natural resource professionals in integrating complex biodiversity concepts into natural resource management processes.

es Searing The Rhizosphere: Belowground Impacts of Prescribed Fires By www.fs.fed.us Published On :: Fri, 14 Apr 2006 15:00:36 PST A century of fire suppression has resulted in dense fuel loads within the dry pine forests of eastern Oregon . To alleviate the risk of stand-replacing wildfire, forest managers are using prescribed fire and thinning treatments. Until recently, the impact of these fuel treatments on soil productivity has been largely unknown. Such information is essential for making sound management decisions about the successful reintroduction of fire to the ecosystem to retain biodiversity of soil fungi and achieve the desired future condition of large ponderosa pines with low fuel loads. In a recent pair of studies, led by researchers at the PNW Forestry Sciences Laboratory in Corvallis, Oregon, novel molecular techniques were utilized to investigate the response of soil ecosystems to prescribed burning and thinning. The research compared impacts of the season of burn and various combinations of fuel-reducing treatments. Results suggest that overly severe fires can damage soil productivity and that less intense fires can be used to gradually reduce accumulations of fuel. The findings are currently being implemented in decisions about forest management and contribute important new information to the science. Full Article
es Northwest Forest Plan-The First 10 Years (1994-2003): Socioeconomic Monitoring Results By www.fs.fed.us Published On :: Fri, 21 Apr 2006 15:25:36 PST The socioeconomic monitoring report addresses two evaluation questions posed in the Northwest Forest Plan (the Plan) Record of Decision and assesses progress in meeting five Plan socioeconomic goals. Volume I of the report contains key findings. Volume II addresses the question, Are predictable levels of timber and nontimber resources available and being produced? It also evaluates progress in meeting the goal of producing a predictable level of timber sales, special forest products, livestock grazing, minerals, and recreation opportunities. The focus of volume III is the evaluation question, Are local communities and economies experiencing positive or negative changes that may be associated with federal forest management? Two Plan goals are also assessed in volume III: (1) to maintain the stability of local and regional economies on a predictable, long-term basis and, (2) to assist with long-term economic development and diversification to minimize adverse impacts associated with the loss of timber jobs. Progress in meeting another Plan goal-to promote agency-citizen collaboration in forest management-is evaluated in volume IV. Volume V reports on trends in public values regarding forest management in the Pacific Northwest over the past decade, community views of how well the forest values and environmental qualities associated with late-successional, old-growth, and aquatic ecosystems have been protected under the Plan (a fifth Plan goal), and issues and concerns relating to forest management under the Plan expressed by community members. Volume VI provides a history of the Northwest Forest Plan socioeconomic monitoring program and a discussion of potential directions for the program. Full Article
es Nontimber Forest Product Opportunities In Alaska By www.fs.fed.us Published On :: Fri, 12 May 2006 12:00:00 PST Nontimber forest products from southern Alaska (also called special forest products) have been used for millennia as resources vital to the livelihoods and culture of Alaska Natives and, more recently, as subsistence resources for the welfare of all citizens. Many of these products are now being sold, and Alaskans seek additional income opportunities through sustainable harvest and manufacture of such forest resources. We discuss the unique legal, regulatory, land tenure, geographic, vegetation, and climatic context that southern Alaska presents for marketing nontimber forest products; summarize the various species and types of products being harvested; and consider the marketing challenges and opportunities new entrepreneurs will encounter. The information and resources we provide are intended to enhance income opportunities for all Alaskans, while sustaining the organisms harvested, respecting traditional activities, and ensuring equitable access to resources.

es WestProPlus: A Stochastic Spreadsheet Program For The Management of All-Aged Douglas-Fir-Hemlock Forests In The Pacific Northwest By www.fs.fed.us Published On :: Thu, 08 Jun 2006 14:00:36 PST WestProPlus is an add-in program developed to work with Microsoft Excel to simulate the growth and management of all-aged Douglas-fir-western hemlock (Pseudotsuga menziesii (Mirb.) Franco-Tsuga heterophylla (Raf.) Sarg.) stands in Oregon and Washington. Its built-in growth model was calibrated from 2,706 permanent plots in the Douglas-fir-western hemlock forest type in Oregon and Washington. Stands are described by the number of trees per acre in each of nineteen 2-in diameter classes in four species groups: Douglas-fir, other shadeintolerant species, western hemlock, and other shade-tolerant species. WestProPlus allows managers to predict stand development by year and for many decades from a specific initial state. The simulations can be stochastic or deterministic. The stochastic simulations are based on bootstrapping of the observed errors in models of stand growth, timber prices, and interest rate. When used in stochastic simulations, this bootstrap technique simulates random variables by sampling randomly (with replacement) from actual observations of the variable, rather than from an assumed distribution. Users can choose cutting regimes by specifying the interval between harvests (cutting cycle) and a target distribution of trees remaining after harvest. A target distribution can be a reverse-J-shaped distribution or any other desired distribution. Diameterlimit cuts can also be simulated. Tabulated and graphic results show diameter distributions, basal area, volumes by log grade, income, net present value, and indices of stand diversity by species and size. This manual documents the program installation and activation, provides suggestions for working with Excel, and gives background information on West-ProPlus's models. It offers a comprehensive tutorial in the form of two practical examples that explain how to start the program, enter simulation data, execute a simulation, compare simulations, and plot summary statistics.

es A Review of Double-Diffusion Wood Preservation Suitable For Alaska By www.fs.fed.us Published On :: Fri, 14 Jul 2006 12:00:00 PST Currently, all treated lumber used in Alaska is imported from the 48 contiguous states and Canada because there are no wood-treating facilities in Alaska. This report explores conventional and alternative wood-treating methods and reviews previous studies and laboratory tests on treated wood. In investigating wood treatment as a possible processing option for Alaska forest products manufacturers, the double-diffusion method of using sodium fluoride followed by a copper sulfate appeared to be the most advantageous approach. This method of treating wood was identified because it can be used to treat freshly cut or green wood. This was an important factor to consider, owing to the limited drying capacity in Alaska. Little information was available as to the chemical retention after treating and its resistance to leaching. Full Article
es Integrated Research In Natural Resources: The Key Role of Problem Framing By www.fs.fed.us Published On :: Fri, 28 Jul 2006 12:00:00 PST Integrated research is about achieving holistic understanding of complex biophysical and social issues and problems. It is driven by the need to improve understanding about such systems and to improve resource management by using the results of integrated research processes. Traditional research tends to fragment complex problems, focusing more on the pieces of problems rather than the whole that comprises multiple interrelationships and interactions. The outcome is that a lot is known about the parts (e.g., recreation, fish, and wildlife) but relatively little about how they are interrelated. There seems to be general agreement that integrated questions must drive the search for integrated understanding, but tradition, inertia, institutional culture,budgets, training, and lack of effective leadership foster reductionism (at worst) or minimal degrees of integration (at best) rather than any substantial, sustainable effort toward integrated research. In this paper, a phased approach to framing integrated research questions and addressing the substantial barriers that impede integrated efforts are discussed. A key conclusion is that to make any significant progress toward comprehensive integrated research will require more than rhetoric. Progress must begin with more effective leadership throughout various levels of research organizations. Full Article
es Northwest Forest Plan-The First 10 Years: Socioeconomic Monitoring of The Olympic National Forest and Three Local Communities By www.fs.fed.us Published On :: Mon, 31 Jul 2006 12:00:00 PST This report examines socioeconomic changes that occurred between 1990 and 2000 associated with implementation of the Northwest Forest Plan (the Plan) in the Olympic National Forest in western Washington. We used a combination of quantitative data from the U.S. census and the USDA Forest Service, historical documents, and interviews from Forest Service employees and members of three case study communities-Quilcene, the Lake Quinault area, and the Quinault Indian Nation. We explore how the Plan affected the flow of socioeconomic benefits associated with the Olympic National Forest, such as the production of forest commodities and forest-based recreation, agency jobs, procurement contract work for ecosystem management activities, grants for community economic assistance, payments to county governments, and opportunities for collaborative forest management. The greatest change in socioeconomic benefits derived from the forest was the curtailment of timber harvest activities. This not only affected timber industry jobs in local communities, but also resulted in declining agency budgets and staff reductions. Mitigation efforts varied. Ecosystem management contracts declined and shifted from labor-intensive to equipment-intensive activities, with about half of all contractors from the Olympic Peninsula. Economic assistance grants benefited communities that had the staff and resources to develop projects and apply for monies, but provided little benefit to communities without those resources. Payments to counties served as an important source of revenue for rural schools and roads. We also examine socioeconomic changes that occurred in the case study communities, and the influence of forest management policy on these changes. Between 1990 and 2000 all three communities showed a decrease in population, an increase in median age, a decline in timber industry-related employment, and an increase in service-industry and government jobs. Quilcene's proximity to the larger urban centers has attracted professional and service industry workers that commute to larger economic hubs. Lake Quinault area residents are increasingly turning to tourism, and its growing Latino population works in the cedar shake and floral greens industries. For the Quinault Indian Nation, employment in tribal government and its casino has helped offset job losses in the fishing and timber industries. Many changes observed in the communities were a result of the prior restructuring of the forest products industry, national economic trends, and demographic shifts. However, for Quilcene and Lake Quinault, which were highly dependent on the national forest for timber and served as Forest Service district headquarters, the loss of timber industry and Forest Service jobs associated with the Plan led to substantial job losses and crises in the economic and social capital of these communities.

es Yellow-Cedar Decline In The North Coast Forest District of British Columbia By www.fs.fed.us Published On :: Mon, 28 Nov 2005 15:25:36 PST The distribution of a forest decline of yellow-cedar (Callitropsis nootkatensis (D. Don) Orsted) has been documented in southeast Alaska, but its occurrence in British Columbia was previously unknown. We conducted an aerial survey in the Prince Rupert area in September 2004 to determine if yellow-cedar forests in the North Coast Forest District of British Columbia were experiencing a similar fate as in nearby Alaska. Numerous large areas of concentrated yellow-cedar mortality were found, extending the known distribution of the decline problem 150 km south of the Alaska-British Columbia border. The forests with the most concentrated tree death occurred at 300 to 400 m elevation, frequently on south aspects. The appearance of these forests including proximity to bogs; mixtures of dying, recently killed, and long-dead trees; and crown and bole symptoms of dying trees were all consistent with the phenomenon in southeast Alaska.

es Sustainable Forestry In Theory and Practice: Recent Advances In Inventory and Monitoring, Statistics and Modeling, Information and Knowledge Management, and Policy Science By www.fs.fed.us Published On :: Fri, 22 Dec 2006 12:00:00 PST The importance to society of environmental services, provided by forest ecosystems, has significantly increased during the last few decades. A growing global concern with the deterioration of forests, beginning perhaps most noticeably in the 1980s, has led to an increasing public awareness of the environmental, cultural, economic, and social values that forests provide. Around the world, ideas of sustainable, close-to-nature, and multi-functional forestry have progressively replaced the older perception of forests as only a source for timber. The international impetus to protect and sustainably manage forests has come from global initiatives at management, conservation, and sustainable development related to all types of forests and forestry. A few of the more notable initiatives include: the 1992 Earth Summit in Rio de Janeiro, Brazil (United Nations Conference on Environment and Development, UNCED); regional follow-ups to the Earth Summit such as the Montreal Process and Helsinki Accords; the forest elements of the Convention on Biological Diversity (CBD); and the Framework Convention on Climate Change (FCCC).

es Growth of Bear-Damaged Trees In A Mixed Plantation of Douglas-Fir and Red Alder By www.fs.fed.us Published On :: Fri, 02 Feb 2007 10:25:10 PST Incidence and effects of tree damage by black bear (Ursus americanus altifrontalis) in a 50-year-old, coast Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii) plantation are described. Bears girdled or partially girdled 35 dominant or codominant Douglas-fir trees per acre, but only in that portion of the plantation that had been interplanted at age 4 with red alder (Alnus rubra Bong). No red alder were damaged. Bears damaged Douglas-fir in this stand on at least four occasions between 1929 (planting) and 1991. Fully girdled Douglas-fir (six per acre in 1976) died within 2 to 14 years. Of the 29 per acre partially girdled trees, 17 percent died in the 16 years of observation, compared to 9 percent of nondamaged trees. Crosssectional growth of surviving damaged trees exceeded that of matched, nondamaged trees by about 30 percent at three heights on the bole: 6 ft, 4.5 ft, and immediately above the damaged area. Death of six large Douglas-fir trees per acre reduced live stand volume of this species for about 6 years after bear damage until growth of the remaining trees compensated for the volume lost to mortality. Confirmation of the stimulating effects of bear damage on subsequent tree growth is needed at other locations. Full Article
es Palau's Forest Resources, 2003 By www.fs.fed.us Published On :: Fri, 02 Feb 2007 10:34:36 PST The Forest Inventory and Analysis Program collected, analyzed, and summarized field data on 54 forested plots on the islands in the Republic of Palau. Estimates of forest area, tree stem volume and biomass, the numbers of trees, tree damages, and the distribution of tree sizes were summarized for this statistical sample. Detailed tables and graphical highlights provide a summary of Palau's forest resources and a comparison to 1987 data. Full Article
es The Fall River Long-Term Site Productivity Study in Coastal Washington: Site Characteristics, Methods, and Biomass and Carbon and Nitrogen Stores Before and After Harvest By www.fs.fed.us Published On :: Fri, 02 Feb 2007 11:00:00 PST The Fall River research site in coastal Washington is an affiliate installation of the North American Long-Term Soil Productivity (LTSP) network, which constitutes one of the world's largest coordinated research programs addressing forest management impacts on sustained productivity. Overall goals of the Fall River study are to assess effects of biomass removals, soil compaction, tillage, and vegetation control on site properties and growth of planted Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco). Biomass-removal treatments included removal of commercial bole (BO), bole to 5-cm top diameter (BO5), total tree (TT), and total tree plus all legacy woody debris (TT+). Vegetation control (VC) effects were tested in BO, while soil compaction and compaction plus tillage were imposed in BO+VC treatment. All treatments were imposed in 1999. The preharvest stand contained similar amounts of carbon (C) above the mineral soil (292 Mg/ha) as within the mineral soil to 80- cm depth including roots (298 Mg/ha). Carbon stores above the mineral soil ordered by size were live trees (193 Mg/ha), old-growth logs (37 Mg/ha), forest floor (27 Mg/ha), old-growth stumps and snags (17 Mg/ha), coarse woody debris (11 Mg/ha), dead trees/snags (7 Mg/ha), and understory vegetation (0.1 Mg/ha). The mineral soil to 80-cm depth contained 248 Mg C/ha, and roots added 41 Mg/ha. Total nitrogen (N) in mineral soil and roots (13 349 kg/ha) was more than 10 times the N store above the mineral soil (1323 kg/ha). Postharvest C above mineral soil decreased to 129, 120, 63, and 50 Mg/ha in BO, BO5, TT, and TT+, respectively. Total N above the mineral soil decreased to 722, 747, 414, and 353 Mg/ha in BO, BO5, TT, and TT+, respectively. The ratio of total C above the mineral soil to total C within the mineral soil was markedly altered by biomass removal, but proportions of total N stores were reduced only 3 to 6 percent owing to the large soil N reservoir on site.

es Considering Communities In Forest Management Planning In Western Oregon By www.fs.fed.us Published On :: Tue, 20 Feb 2007 12:00:00 PST A recurrent theme in the development of U.S. forest policies has been the assertion of strong positive relations among communities, economies, and natural resource management. Now as a new round of federal land management planning is getting underway, questions are being raised about the strength of that assertion and how to view communities following a decade of reduced federal harvests. This report examines these questions considering the 433 communities in six Bureau of Land Management districts in western Oregon. It discusses the ways that forest-based communities have been considered in the context of federal forest management planning, and it summarizes information on socioeconomic conditions and trends for communities in western Oregon.

es Managing For Wildlife Habitat In Westside Production Forests By www.fs.fed.us Published On :: Tue, 20 Feb 2007 12:00:00 PST On October 18, 2006, a workshop was held in Vancouver, WA, with the title "Managing for wildlife habitat in Westside production forests." The purpose of the workshop was to provide prescriptions and guidelines for people who manage Westside forests (those west of the Cascade Mountains' crest) primarily for wood production, but because of mandate or personal preference, want to integrate wildlife values. The audience included over 150 professionals from forest industry, consulting firms, and public and tribal forest and wildlife management agencies. This proceedings includes ten papers based on oral presentations at the workshop plus a synthesis paper summarizing workshop themes, discussions, and related information. Topics include a history of wildlife management research in the Pacific Northwest, elements of habitat and how to manage for them, the challenges of appropriately implementing ecosystem management, and economic implications to private forestland owners.
