academic and careers National forests on the edge: development pressures on America's national forests and grasslands By www.fs.fed.us Published On :: Mon, 25 Oct 2007 13:10:00 PST Many of America's national forests and grasslands--collectively called the National Forest System--face increased risks and alterations from escalating housing development on private rural lands along their boundaries. National forests and grasslands provide critical social, ecological, and economic benefits to the American public. This study projects future housing density increases on private rural lands at three distances--2, 3, and 10 miles--from the external boundaries of all national forests and grasslands across the conterminous United States. Some 21.7 million acres of rural private lands (about 8 percent of all private lands) located within 10 miles of the National Forest System boundaries are projected to undergo increases in housing density by 2030. Nine national forests are projected to experience increased housing density on at least 25 percent of adjacent private lands at one or more of the distances considered. Thirteen national forests and grasslands are each projected to have more than a half-million acres of adjacent private rural lands experience increased housing density. Such development and accompanying landscape fragmentation pose substantial challenges for the management and conservation of the ecosystem services and amenity resources of National Forest System lands, including access by the public. Research such as this can help planners, managers, and communities consider the impacts of local land use decisions. Full Article
academic and careers Taper equation and volume tables for plantation-grown red alder By www.fs.fed.us Published On :: Wed, 07 Nov 2007 08:00:00 PST A taper equation and associated tables are presented for red alder (Alnus rubra Bong.) trees grown in plantations. The data were gathered from variable-density experimental plantations throughout the Pacific Northwest. Diameter inside bark along the stem was fitted to a variable exponent model form by using generalized nonlinear least squares and a first-order continuous autoregressive process. A number of parameterizations of the exponent were examined in a preliminary analysis, and the most appropriate form was determined. This was achieved by examining alternative models across geographic locations and silvicultural treatments on the basis of their ability to behave well outside the range of the modeling data by using an independent evaluation data set from across the region and a model validation procedure. Incorporating three easily measured tree variables--diameter at breast height, total tree height, and crown ratio--provided the best fit among location and treatment. This taper equation can be used to estimate diameter inside bark anywhere along the stem, inside bark volume of the entire stem to any top height diameter, and merchantable height and volume between any two points along the stem (i.e., individual log volumes). The flexibility of the model allows for accurate volume predictions across a range of operational stand conditions and management activities and is therefore an improvement over previously published red alder volume and taper equations.

academic and careers Sociocultural effects of tourism in Hoonah, Alaska By www.fs.fed.us Published On :: Wed, 07 Nov 2007 08:00:00 PST This report examines the growth and development of the tourism industry in Hoonah, Alaska, and its effects on community life and resource use. The report describes the gradual development of tourism in Hoonah and presents resident perceptions of tourism's effect on the natural and social environment. A multisited ethnographic approach was used featuring indepth, open-ended interviews with local residents, tourism providers, business owners, and government officials. Data were analyzed using Ethnograph, a software program used to assist in coding data based on prominent themes. Results indicate that tourism has brought changes to the lives of Hoonah residents, particularly those relying on natural resources for everyday survival. Expansion of nature-based tourism in the area surrounding Hoonah resulted in conflicts between resource users. The growth of the charter fishing fleet led to competition with commercial fishers. Nature tour operators using remote recreation sites experienced conflicts with local hunters and fishers as well as other commercial guides. The development of a cruise ship destination on private land outside of Hoonah led to shifts in use of this historic site by local residents as well as in use of other private lands used for subsistence. Findings may enable Forest Service planners to identify factors involved in the relation between tourism growth and community well-being. It also may assist small southeast Alaska communities in decisionmaking related to tourism development. Full Article

academic and careers Growth of Douglas-fir near equipment trails used for commercial thinning in the Oregon Coast Range By www.fs.fed.us Published On :: Fri, 18 Jan 2008 15:08:00 PST Soil disturbance is a visually apparent result of using heavy equipment to harvest trees. Subsequent consequences for growth of remaining trees, however, are variable and seldom quantified. We measured tree growth 7 and 11 years after thinning of trees in four stands of coast Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb. Franco)) where soil disturbance was limited by using planned skid trails, usually on dry soils. The three younger stands had responded to nitrogen fertilizer in the 4 years before thinning, but only one stand showed continued response in the subsequent 7- or 11-year period after thinning. The most consistent pattern observed was greater growth of residual trees located next to skid trails. The older stand also showed greater growth in trees located next to skid trails, whereas tillage of skid trails failed to benefit growth of nearby residual trees for the first 7 years after tillage. We conclude that traffic that compacted soil only on one side of residual trees did not reduce growth of nearby trees. Full Article
academic and careers Northwest Forest Plan-the first 10 years (1994-2003): first-decade results of the Northwest Forest Plan By www.fs.fed.us Published On :: Tue, 19 Feb 2008 11:05:00 PST The Northwest Forest Plan (the Plan) was developed in 1994 to resolve debates over old-growth forests and endangered species on federal forests in the range of the northern spotted owl. In 2005, federal agencies reviewed the first 10 years under the Plan to learn what worked and what did not, what changed, and what new information or surprises might influence these forests in the future. I highlight the monitoring results and new science from that review. Following are some of the key findings. Nearly all existing older forest habitat on federal land was protected from timber harvest. Older forest on federal land had a net increase of over 1 million acres in the first 10 years of the Plan. Despite protection of northern spotted owl habitat on federal land, spotted owl populations declined at a greater rate than expected in the northern half of their range, likely because of barred owl competition, climate, and the changing condition of historical habitat. Watershed condition improved slightly, because of reduced harvest in riparian areas, tree growth, and increased emphasis on restoration. Federal timber harvest in the Plan area averaged only 54 percent of Plan goals. In spite of mitigation measures, some local communities near federal lands had job losses and other adverse effects. State, federal, and tribal governments worked together on forest issues better than they ever had before. Increased collaboration with communities changed how the agencies get work done. Full Article
academic and careers Water and people: challenges at the interface of symbolic and utilitarian values By www.fs.fed.us Published On :: Tue, 19 Feb 2008 11:10:00 PST The demand for water is rapidly increasing, but the uses to which that water is put and the values society places on water are changing dramatically. Water is the source of life, the sustenance for living, the resource needed for manufacturing, mining, agriculture; the element required to grow our lawns, to water our landscaping, to shower us with refreshment; it is the place where we play; it provides the snow for our winter recreation, and it provides the habitat for much of our wildlife. Water in contemporary American society is more than a simple physical entity, its symbolic values, and noninstrumental uses are growing in significance. As with many Native American cultures, water is as much a symbol as it is something to extract and use in the production of commercial products. This book is about the issues associated with these symbolic values and uses of water: the challenges they present--in our language, in our allocation mechanisms, in our communication--the conflicts raised; and the potential for resolving the difficult, contentious and complex issues concerning the use of water for various purposes. It is as much about framing the questions about symbolic values of water as it is anything else. Full Article
academic and careers National Visitor Use Monitoring implementation in Alaska By www.fs.fed.us Published On :: Tue, 19 Feb 2008 11:15:00 PST The USDA Forest Service implemented the National Visitor Use Monitoring (NVUM) program across the entire National Forest System (NFS) in calendar year 2000. The primary objective of the NVUM program is to develop reliable estimates of recreation use on NFS lands via a nationally consistent, statistically valid sampling approach. Secondary objectives of NVUM are to characterize recreation visits, collect data in support of regional economic analyses, and gauge national forest visitor satisfaction. We document and review the round 1 NVUM implementation in the USDA Forest Service Alaska Region (R-10) with examination of the R-10 prework, sample day implementation, survey completion rates, sampling at cabins, boat docks, and air carriers; and the NVUM expansion weights assigned to survey cases. Several opportunities to improve the implementation of the standard NVUM protocols in R-10 are identified. Full Article

academic and careers A review of the literature on seed fate in whitebark pine and the life history traits of Clark's nutcracker and pine squirrels By www.fs.fed.us Published On :: Mon, 21 Apr 2008 11:15:00 PST Whitebark pine is a critical component of subalpine ecosystems in western North America, where it contributes to biodiversity and ecosystem function and in some communities is considered a keystone species. Whitebark pine is undergoing rangewide population declines attributed to the combined effects of mountain pine beetle, white pine blister rust, and fire suppression. The restoration and maintenance of whitebark pine populations require an understanding of all aspects of seed fate. In this paper, we review the literature on seed dispersal in whitebark pine. Clark's nutcracker, pine squirrels, and scatter-hoarding rodents are all known to influence whitebark pine seed fate and ultimately affect the ability of whitebark pine populations to regenerate. We also provide a general overview of the natural histories of the most influential species involved with whitebark pine seed fate: Clark's nutcracker and the pine squirrel. Full Article
academic and careers Forest inventory-based estimation of carbon stocks and flux in California forests in 1990 By www.fs.fed.us Published On :: Mon, 21 Apr 2008 11:20:00 PST Estimates of forest carbon stores and flux for California circa 1990 were modeled from forest inventory data in support of California's legislatively mandated greenhouse gas inventory. Reliable estimates of live-tree carbon stores and flux on timberlands outside of national forest could be calculated from periodic inventory data collected in the 1980s and 1990s; however, estimation of circa 1990 flux on national forests and forests other than timberland was problematic owing to a combination of changing inventory protocols and definitions and the lack of remeasurement data on those land categories. We estimate annual carbon flux on the 7.97 million acres of timberlands outside of national forests (which account for 24 percent of California's forest area and 28 percent of its live tree aboveground biomass) at 2.9 terragrams per year.

academic and careers Evaluation of landscape alternatives for managing oak at Tenalquot Prairie, Washington By www.fs.fed.us Published On :: Thu, 01 May 2008 08:15:00 PST In recent years, interest has increased in restoring Oregon white oak (Quercus garryana Dougl. ex Hook.) and prairie landscapes in the Pacific Northwest, especially where elements of historical plant communities are intact. We evaluated the effect of alternative management scenarios on the extent and condition of Oregon white oak, the extent of prairie, and the harvest and standing volumes of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) within a 2934-ha portion of Fort Lewis, Washington (named the Tenalquot Planning Area for the purpose of the project). A landscape-level analysis of the scenarios was completed using a geographic information system, a forest growth model (ORGANON), and landscape visualization software (EnVision). The scenarios ranged from no active management to restoration of the historical extent of oak and prairies within the planning area. The results indicate that the window of opportunity for restoring oak and prairie landscapes in the Puget Sound lowlands and other regions is small, and aggressive management is needed to maintain or enhance these landscapes. The project demonstrates the value of landscape level analyses and the use of new technologies for conveying the results of alternative management scenarios. Full Article
academic and careers Emergent lessons from a century of experience with Pacific Northwest timber markets By www.fs.fed.us Published On :: Thu, 01 May 2008 08:15:00 PST Timber markets in the United States are areas where timber prices tend to be uniform because of the continuous interactions of buyers and sellers. These markets are highly competitive, volatile, and change relentlessly. This paper looks at how market interactions in the Pacific Northwest have responded to changes in underlying determinants of market behavior and government actions that have influenced supply or demand. Several messages emerge from timber markets about price reporting and changing definitions of price, long-term price trends, timber as an investment, impacts of market intervention, relations among different markets, and implications for future stewardship. The enduring message is that landowners and managers respond to price signals arising from market interactions, and their actions create the forests inherited by future generations. Full Article
academic and careers True fir spacing trials: 10-year results By www.fs.fed.us Published On :: Thu, 01 May 2008 08:15:00 PST Eighteen precommercial thinning trials were established in true fir-hemlock stands in the Olympic Mountains and the west side of the Cascade Range during the period 1987 through 1994. This paper updates a previous report, with results for the first 10 years after establishment. Results are given for (1) all trees, (2) the largest 80 per acre of any species, and (3) those noble fir (Abies procera Rehd.) and Pacific silver fir (Abies amabilis Dougl. ex Forbes) included in the largest 80 per acre. Diameter growth of all species increased with increase in spacing. Height growth of Pacific silver fir decreased with increase in spacing. The largest 80 trees per acre of all species showed some increase in diameter and basal area growth with increased spacing, while height growth declined slightly and volume growth was nearly constant. Over time, these installations will provide a unique source of information on early development of managed stands of these species, for which little information is now available. Full Article
academic and careers A protocol using coho salmon to monitor Tongass National Forest Land and Resource Management Plan standards and guidelines for fish habitat By www.fs.fed.us Published On :: Thu, 22 May 2008 14:00:00 PST We describe a protocol to monitor the effectiveness of the Tongass Land Management Plan (TLMP) management standards for maintaining fish habitat. The protocol uses juvenile coho salmon (Oncorhynchus kisutch) in small tributary streams in forested watersheds. We used a 3-year pilot study to develop detailed methods to estimate juvenile salmonid populations, measure habitat, and quantitatively determine trends in juvenile coho salmon abundance over 10 years. Coho salmon have been shown to be sensitive to habitat alterations, and we use coho salmon parr as the primary indicator in the protocol. A priori criteria for type I and type II error rates, effect size, and sample sizes for the protocol were derived with estimates of variance computed from the 3-year pilot study. The protocol is designed to detect trends in abundance of coho salmon parr, as well as coho salmon fry and Dolly Varden (Salvelinus malma), in small streams managed according to TLMP standards and guidelines and to compare these to trends in unmanaged (old-growth) watersheds. Trends are adjusted to account for statistically significant habitat covariates. This information provides an important element in monitoring land management practices in the Tongass National Forest. The methods we describe may have application to monitoring protocols elsewhere for fish populations and land management practices. Full Article
academic and careers Understanding concepts of place in recreation research and management By www.fs.fed.us Published On :: Thu, 22 May 2008 14:00:00 PST Over a 3-day weekend in the spring of 2004 a group of scientists interested in extending understanding of place as applied in recreation research and management convened a working session in Portland, Oregon. The purpose of the gathering was to clarify their understanding of place-related concepts, approaches to the study of people-place relations, and the application of that understanding in recreation management for the purpose of integrating perspectives from different disciplines, discussing approaches to understanding and measuring sense of place, and other questions around the study and application of place-related concepts. Topics that generated the most discussion included how social processes influence place meanings, how place meanings are shared and negoitated within social groups, and when and how place meanings and attachments focus, reduce, or avert conflict in natural resource planning and management. This collection of papers is a result of that meeting. Full Article

We address four topics: (1) views and values people have relating to biodiversity, (2) the resource use and management practices of local forest users and their effects on biodiversity, (3) methods and models for integrating traditional and local ecological knowledge into biodiversity conservation on public and private lands, and (4) challenges to applying traditional and local ecological knowledge for biodiversity conservation. We focus on the ecological knowledge of three groups who inhabit the region: American Indians, family forest owners, and commercial nontimber forest product (NTFP) harvesters. Full Article
academic and careers Soils under fire: soils research and the Joint Fire Science Program By www.fs.fed.us Published On :: Thu, 22 May 2008 14:00:00 PST Soils are fundamental to a healthy and functioning ecosystem. Therefore, forest land managers can greatly benefit from a more thorough understanding of the ecological impacts of fire and fuel management activities on the vital services soils provide. We present a summary of new research on fire effects and soils made possible through the Joint Fire Science Program and highlight management implications where applicable. Some responses were consistent across sites, whereas others were unique and may not easily be extrapolated to other sites. Selected findings include (1) postfire soil water repellency is most likely to occur in areas of high burn severity and is closely related to surface vegetation; (2) although wildfire has the potential to decrease the amount of carbon stored in soils, major changes in land use, such as conversion from forest to grasslands, present a much greater threat to carbon storage; (3) prescribed fires, which tend to burn less severely than wildfires and oftentimes have minor effects on soils, may nonetheless decrease species richness of certain types of fungi; and (4) early season prescribed burns tend to have less impact than late season burns on soil organisms, soil carbon, and other soil properties.

academic and careers A synthesis of biomass utilization for bioenergy production in the Western United States By www.fs.fed.us Published On :: Mon, 16 Jun 2008 09:15:00 PST We examine the use of woody residues, primarily from forest harvesting or wood products manufacturing operations (and to a limited degree from urban wood wastes), as a feedstock for direct-combustion bioenergy systems for electrical or thermal power applications. We examine opportunities for utilizing biomass for energy at several different scales, with an emphasis on larger scale electrical power generation at stand-alone facilities, and on smaller scale facilities (thermal heating only) such as governmental, educational, or other institutional facilities. We then identify west-wide barriers that tend to inhibit bioenergy applications, including accessibility, terrain, harvesting costs, and capital costs. Finally, we evaluate the role of government as a catalyst in stimulating new technologies and new uses of biomass material. Full Article
academic and careers Incorporating understanding of informal economic activity in natural resource and economic development policy By www.fs.fed.us Published On :: Mon, 16 Jun 2008 09:15:00 PST This report synthesizes the literature on the role of informal economic activity in the United States postindustrial economy. Informal economic activity is expanding in the United States and is likely to continue in the foreseeable future. The formal and informal economic sectors are inextricably intertwined, with individuals and households combining elements of both sectors to construct their livelihoods. Although the informal economy is often thought of as the domain of economically marginal individuals and households, virtually everyone participates in the informal economy to some extent. However, the literature highlights how factors such as social status and household position in the formal economy affect whether participation in informal economic activity is exploitative or empowering. The nontimber forest products sector serves as a case study of why it is important to consider informal economic activity when developing natural resource and economic development policy. We recommend steps policymakers can take to identify and encourage positive aspects of the informal economic activity. We also highlight several areas of research to improve understandings of the role of informal economic activity in postindustrial societies. Full Article
academic and careers A closer look at forests on the edge: future development on private forests in three states By www.fs.fed.us Published On :: Mon, 16 Jun 2008 09:15:00 PST Privately owned forests provide many public benefits, including clean water and air, wildlife habitat, and recreational opportunities. By 2030, 44.2 million acres of rural private forest land across the conterminous United States are projected to experience substantial increases in residential development. As housing density increases, the public benefits provided by private forests can be permanently altered. We examine factors behind projected patterns of residential development and conversion of private forest land by 2030 in northwestern Washington, southern Maine, and northwestern Georgia. Some key factors affecting the extent of future residential housing include (1) population growth from migration into an area; (2) historical settlement patterns, topography, and land ownership; and (3) land use planning and zoning.

academic and careers Influence of four tree shelter types on microclimate and seedling performance of Oregon white oak and western redcedar By www.fs.fed.us Published On :: Tue, 08 Jul 2008 09:10:00 PST Four types of tree shelters were evaluated in southwestern Washington for their effects on seedling microenvironment and performance of two tree species. Shelter types were fine-mesh fabric shelters, solid-walled white shelters with and without vent holes, and solid-walled blue unvented shelters. Summer mean and daily maximum air temperatures were increased by 0.8 degrees C and 3.6 degrees C, respectively, in solid-walled tree shelters. Shelter color and shelter venting did not influence air temperatures. Tree shelters only affected vapor pressure deficit late in the growing season. Midday photosynthetically active radiation within shelters ranged from 54 percent of full sun in fine-mesh fabric shelters to 15 percent of full sun in blue solid-walled shelters. In the first year after planting, height and diameter growth of western redcedar (Thuja plicata Donn ex D. Don) were significantly increased by all shelter types, with blue solid-walled shelters resulting in the greatest height growth. However, in blue solid-walled shelters, photosynthesis and stem diameter growth of Oregon white oak (Quercus garryana Dougl. ex Hook.) seedlings were significantly less than for unsheltered seedlings.

academic and careers Calibration and modification for the Pacific Northwest of the New Zealand Douglas-fir silvicultural growth model By www.fs.fed.us Published On :: Tue, 08 Jul 2008 09:10:00 PST This paper describes a growth model for young plantations of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) growing in the Pacific Northwest. The overall model has three major components. The first is a yield model for diameter and height distributions describing stands prior to pruning or precommercial thinning. The second component is an annual per-acre net increment model adapted from a recent model for Douglas-fir plantations in New Zealand; thinning and pruning are features of the model. The third component is growth equations for cohorts of individual trees; the results from this component are adjusted to match those from the second component. Fitting data are from Stand Management Cooperative experiments, with top heights generally below 75 ft. An intended use of the model is the evaluation of pruning regimes, in conjunction with the ORGANON model for growth at older ages, and TREEVAL model for clear-wood recovery and economic evaluation.

academic and careers Northwest Forest Plan-the first 10 years (1994-2003): Socioeconomic monitoring of the Okanogan-Wenatchee National Forest and five local communities By www.fs.fed.us Published On :: Tue, 08 Jul 2008 09:10:00 PST This report examines socioeconomic changes that occurred between 1990 and 2003 associated with implementation of the Northwest Forest Plan (the Plan) in and around lands managed by the Okanogan-Wenatchee National Forest in Washington state. Our findings are based on quantitative data from the U.S. census, the USDA Forest Service and other federal databases, historical documents, and interviews with Forest Service employees and members of five case study communities: Naches Valley, Cashmere, Entiat, Twisp, and the Upper Okanogan Valley. We explore how the Plan affected the flow of socioeconomic benefits associated with the Okanogan-Wenatchee 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 socioeconomic change stemming from the national forest during the study period was the sharp decline in timber harvest activities, a change that had been underway prior to the Plan. This decline not only affected timber industry jobs in local communities, but also resulted in declining agency budgets and staff reductions. Communities' responses differed.

academic and careers Cordwood energy systems for community heating in Alaska--an overview. By www.fs.fed.us Published On :: Tue, 03 Feb 2009 15:50:00 PST Wood has become an important energy alternative in Alaska, particularly in rural areas where liquid fuel costs can be substantial. In some cases, wood fuel is readily available to communities, increasing the attractiveness of wood energy. Wood energy systems in rural Alaska can also lead to employment gains as well as benefits to local cash economies. Many Alaska villages are now considering wood as a fuel source for community heating, several have completed feasibility studies, and others are moving forward with design and construction activities. Cordwood is readily available in many regions of Alaska, although not always in commercial quantities. However, for many small-scale applications, efficient cordwood systems could be a viable energy option. In this paper, we provide a qualitative review of factors such as wood fuel availability, cordwood system size, wood fuel cost, wood quality, labor, fuel drying, and underground piping. Other general observations are noted, based on case studies of operating cordwood systems in Alaska. Full Article
academic and careers Estimating sawmill processing capacity for Tongass timber: 2005 and 2006 update By www.fs.fed.us Published On :: Tue, 3 Feb 2009 13:37:00 PST In spring 2006 and 2007, sawmill capacity and wood utilization information was collected for selected mills in southeast Alaska. The collected information is required to prepare information for compliance with Section 705(a) of the Tongass Timber Reform Act. The total estimated design capacity in the region (active and inactive mills) was 289,850 thousand board feet (mbf) Scribner log scale in calendar year (CY) 2005 and 284,350 mbf in CY 2006. The estimated design capacity of active mills was 259,850 mbf for CY 2005 and 247,850 mbf for CY 2006. This is a 2.9-percent decrease in active design capacity from CY 2004 (255,350 mbf) to CY 2006. The estimated volume of material processed during CY 2006 was 32,141 mbf Scribner log scale. This is a 3.6-percent increase over CY 2004 (31,027 mbf Scribner log scale). Full Article
academic and careers Dry forests of the Northeastern Cascades Fire and Fire Surrogate Project site, Mission Creek, Okanogan-Wenatchee National Forest By www.fs.fed.us Published On :: Wed, 08 Feb 2009 09:10:00 PST The Fire and Fire Surrogate (FFS) project is a large long-term metastudy established to assess the effectiveness and ecological impacts of burning and fire "surrogates" such as cuttings and mechanical fuel treatments that are used instead of fire, or in combination with fire, to restore dry forests. One of the 13 national FFS sites is the Northeastern Cascades site at Mission Creek on the Okanogan- Wenatchee National Forest. The study area includes 12 forested stands that encompass a representative range of dry forest conditions in the northeastern Cascade Range. We describe site histories and environmental settings, experimental design, field methods, and quantify the pretreatment composition and structure of vegetation, fuels, soils and soil biota, entomology and pathology, birds, and small mammals that occurred during the 2000 and 2001 field seasons. We also describe the implementation of thinning treatments completed during 2003 and spring burning treatments done during 2004 and 2006. Full Article
academic and careers An evaluation of the grades and value of red alder lumber in southeast Alaska By www.fs.fed.us Published On :: Tue, 17 Feb 2009 16:40:00 PDT Many stands in southeast Alaska harvested since 1950, especially where there has been a high degree of disturbance of mineral soil, have regenerated to red alder (Alnus rubra Bong.) and are now approaching maturity. The availability of red alder raises questions addressed in this study about the recovery of lumber from this resource. Information in this study was obtained from trees estimated to be 46 years old on a site outside of Ketchikan. Rates of recovery using a thin-kerf portable band mill were higher than those reported by larger production mills in Washington and Oregon. Grade yields of the Alaska material are comparable to those attained in other regions. This study determined that there were no significant differences in material characteristics that would set this Alaska log resource apart from red alder in the other regions of North America. The potential value of the products is sufficient to allow production in Alaska for use in the manufacturing of value-added products within the state or shipment of finished lumber to domestic or export markets.

academic and careers Adoption of engineered wood products in Alaska By www.fs.fed.us Published On :: Tue, 24 Feb 2009 14:40:00 PST Based on an in-grade testing program, the Ketchikan Wood Technology Center has registered three proprietary grademarks for Alaska species of hemlock (Tsuga heteraphylla (Raf.) Sarg.), yellow-cedar (Chamaecyparis nootkatensis (D. Don) Spach), and spruce (combined Sitka spruce [Picea sitchensis (Bong.) Carr.] and white spruce [Picea glauca (Moench) Voss]). The Ketchikan Wood Technology Center conducted tests to establish glulam beam manufacturing specifications. In conjunction with this program, there is a need to measure the market for glulam beams in Alaska. The purpose of this research was to compare Alaska residential builder adoption rates of glulam beams and other engineered wood products to those of the continental United States. The results showed that a higher percentage of Alaska builders use glulam beams compared with builders in the rest of the United States. Full Article

academic and careers Effects of timber harvest following wildfire in western North America By www.fs.fed.us Published On :: Fri, 06 Mar 2009 10:10:00 PST Timber harvest following wildfire leads to different outcomes depending on the biophysical setting of the forest, pattern of burn severity, operational aspects of tree removal, and other management activities. Fire effects range from relatively minor, in which fire burns through the understory and may kill a few trees, to severe, in which fire kills most trees and removes much of the organic soil layer. Postfire logging adds to these effects by removing standing dead trees (snags) and disturbing the soil. The influence of postfire logging depends on the intensity of the fire, intensity of the logging operation, and management activities such as fuel treatments. In severely burned forest, timing of logging following fire (same season as fire vs. subsequent years) can influence the magnitude of effects on naturally regenerating trees, soils, and commercial wood value. Removal of snags reduces long-term fuel loads but generally results in increased amounts of fine fuels for the first few years after logging unless surface fuels are effectively treated. By reducing evapotranspiration, disturbing the soil organic horizon, and creating hydrophobic soils in some cases, fire can cause large increases in surface-water runoff, streamflow, and erosion. Through soil disturbance, especially the construction of roads, logging with ground-based equipment and cable yarding can exacerbate this effect, increasing erosion and altering hydrological function at the local scale. Effects on aquatic systems of removing trees are mostly negative, and logging and transportation systems that disturb the soil surface or accelerate road-related erosion can be particularly harmful unless disturbances are mitigated. Cavity-nesting birds, small mammals, and amphibians may be affected by harvest of standing dead and live trees, with negative effects on most species but positive or neutral effects on other species, depending on the intensity and extent of logging. Data gaps on postfire logging include the effects of various intensities of logging, patch size of harvest relative to fire size, and long-term (10+ years) biophysical changes. Uncertainty about the effects of postfire logging can be reduced by implementing management experiments to document long-term changes in natural resources at different spatial scales. Full Article
academic and careers Ecological foundations for fire management in North American forest and shrubland ecosystems By www.fs.fed.us Published On :: Thu, 19 Mar 2009 11:45:00 PST This synthesis provides an ecological foundation for management of the diverse ecosystems and fire regimes of North America, based on scientific principles of fire interactions with vegetation, fuels, and biophysical processes. Although a large amount of scientific data on fire exists, most of those data have been collected at small spatial and temporal scales. Thus, it is challenging to develop consistent science-based plans for large spatial and temporal scales where most fire management and planning occur. Understanding the regional geographic context of fire regimes is critical for developing appropriate and sustainable management strategies and policy. The degree to which human intervention has modified fire frequency, intensity, and severity varies greatly among different ecosystems, and must be considered when planning to alter fuel loads or implement restorative treatments. Detailed discussion of six ecosystems--ponderosa pine forest (western North America), chaparral (California), boreal forest (Alaska and Canada), Great Basin sagebrush (intermountain West), pine and pine-hardwood forests (Southern Appalachian Mountains), and longleaf pine (Southeastern United States)--illustrates the complexity of fire regimes and that fire management requires a clear regional focus that recognizes where conflicts might exist between fire hazard reduction and resource needs. In some systems, such as ponderosa pine, treatments are usually compatible with both fuel reduction and resource needs, whereas in others, such as chaparral, the potential exists for conflicts that need to be closely evaluated. Managing fire regimes in a changing climate and social environment requires a strong scientific basis for developing fire management and policy. Full Article

academic and careers Diversity, ecology, and conservation of truffle fungi in forests of the Pacific Northwest By www.fs.fed.us Published On :: Tue, 28 Apr 2009 08:40:00 PST Forests of the Pacific Northwest have been an epicenter for the evolution of truffle fungi with over 350 truffle species and 55 genera currently identified. Truffle fungi develop their reproductive fruit-bodies typically belowground, so they are harder to find and study than mushrooms that fruit aboveground. Nevertheless, over the last five decades, the Corvallis Forest Mycology program of the Pacific Northwest Research Station has amassed unprecedented knowledge on the diversity and ecology of truffles in the region. Truffle fungi form mycorrhizal symbioses that benefit the growth and survival of many tree and understory plants. Truffle fruit-bodies serve as a major food souce for many forest-dwelling mammals. A few truffle species are commercially harvested for gourmet consumption in regional restaurants. This publication explores the biology and ecology of truffle fungi in the Pacific Northwest, their importance in forest ecosystems, and effects of various silvicultural practices on sustaining truffle populations. General management principles and considerations to sustain this valuable fungal resource are provided. Full Article
academic and careers Outdoor recreation in the Pacific Northwest and Alaska: trends in activity participation By www.fs.fed.us Published On :: Tue, 12 May 2009 16:40:00 PDT Population growth in Oregon, Washington, and Alaska is expected to increase demand for outdoor recreation on public land. This trend will be tempered by changes in the sociodemographic composition of the population. Among sociodemographic characteristics, different ages and incomes correspond to different participation rates. Although older Americans are participating more, participation is still lower among this group for active pursuits. Hence, as the population ages, demand for passive activities may increase. Low-income people participate at a much lower rate than higher income people in outdoor recreation, and the growing disparity between the wealthy and poor may create inequities in opportunities for participation. State recreation planning documents for Oregon, Washington, and Alaska have identified this issue as a significant concern for recreation providers. Another important factor in recreation trends in the region is ethnicity: different ethnic groups participate in outdoor recreation at different rates, exhibit some different preferences for specific activities, and use recreation sites in different ways. In Alaska, the number of Asian/Pacific Islanders is expected to quadruple by 2025; in Oregon, the Hispanic population may triple by 2025; and in Washington, both these segments of the population may double.
