During this period, FIA conducted 972 surveys of epiphytic macrolichen communities for monitoring both spatial and long-term temporal trends in forest health. Major research findings are presented with emphasis on lichen biodiversity as well as bioindication of air quality and climate. Considerable effort is devoted to mapping geographic patterns and defining lichen indicator species suitable for estimating air quality and climate. Full Article
re 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
re 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.

re 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
re 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
re 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

re Traditional and local ecological knowledge about forest biodiversity in the Pacific Northwest By www.fs.fed.us Published On :: Thu, 22 May 2008 14:00:00 PST This paper synthesizes the existing literature about traditional and local ecological knowledge relating to biodiversity in Pacific Northwest forests in order to assess what is needed to apply this knowledge to forest biodiversity conservation efforts. 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
re 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.

re 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
re 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.

re 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.

re 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. Communities with greater economic diversity were able to absorb the changes in forest management, whereas communities more heavily dependent on timber experienced an additional destabilizing effect.

re 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
re 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.

re 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

re 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
re 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
re 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
re 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.

re Wood energy for residential heating in Alaska: current conditions, attitudes, and expected use. By www.fs.fed.us Published On :: Tue, 20 Jul 2010 14:10:00 PST This study considered three aspects of residential wood energy use in Alaska: current conditions and fuel consumption, knowledge and attitudes, and future use and conditions. We found that heating oil was the primary fuel for home heating in southeast and interior Alaska, whereas natural gas was used most often in south-central Alaska (Anchorage). Firewood heating played a much more important role as a secondary (vs. primary) heating source in all regions of Alaska. In interior Alaska, there was a somewhat greater interest in the use of wood energy compared to other regions. Likewise, consumption of fossil fuels was considerably greater in interior Alaska.

re Trends in global shipping and the impact on Alaska's forest products By www.fs.fed.us Published On :: Mon 29 Aug 2011 1350:00 PST Traditionally, there has been a strong forest products trade between Alaska and Asia. This trade relationship has developed owing to Alaska's proximity to Asia and, in the past, an abundance of high-quality timber. Although forest products markets in North America remain soft, markets in Asia are growing. However, to benefit from Asia's growing forest products market, it is important to understand the concepts of global shipping including containerization, intermodal transport, non vessel operating common carriers, and freight forwarders. One key development that could have a major impact on Alaska's forest products trade is the opening of the Port of Prince Rupert (British Columbia) in 2007. The Port of Prince Rupert ships lumber, logs, and wood pellets to Asia and is much closer to southeast Alaska than are the ports of Seattle and Tacoma. The Prince Rupert port is also 1 day closer to Asia. Despite Prince Rupert's proximity to Alaska, however, there is still no regularly scheduled barge service between the Port of Prince Rupert and southeast Alaska. Potential connections that may develop are examined in this paper. This paper also examines the changing concepts of global shipping and how they affect Alaska's forest products industry.

re Giving credit where credit is due: increasing landowner compensation for ecosystem services. By www.fs.fed.us Published On :: Wed, 06 Apr 2011 11:04:00 PST Conservation of biodiversity serves a number of human needs, including maintenance of ecosystem services that are critical to the sustainability of all life. Effective biodiversity conservation will require better landowner incentives for restoration and protection of ecosystems. Many services produced from healthy, functioning landscapes are not well recognized in current conservation incentive structures, including sequestering or storing carbon in trees and soil, providing fish and wildlife habitat, filtering water, and reducing damages from natural disasters. Most existing incentive programs pay landowners to protect and restore a specific service rather than the suite of services produced from well-functioning ecosystems. Full Article

re Quantifying competitive ability of perennial grasses to inhibit Scotch broom. By www.fs.fed.us Published On :: Fri, 10 Jun 2011 14:35:00 PST Greenhouse pot studies were conducted to quantify the competitive abilities of three native perennial grass species to inhibit development of Scotch broom (Cytisus scoparius (L.) Link ) seedlings: spike bentgrass (Agrostis exarata Trin. ), blue wildrye (Elymus glaucus Buckley), and western fescue (Festuca occidentalis Hook. ). In single-species stands (1) soil water content decreased with increasing grass density, (2) soil water depletion per plant differed among species as ratios of 2.4:1.3:1 for bentgrass, fescue, and wildrye, respectively, and (3) average percentage of ground cover per plant was ranked by species as bentgrass (14 percent), wildrye (8 percent), broom (8 percent), and fescue (5 percent). Regression models predicted 90, 85, and 72 percent reductions in average biomass per plant of broom when grown with approximately 250 plants/m2 of bentgrass, wildrye, and fescue, respectively. Bentgrass and wildrye were more competitive than fescue because of their early-season depletion of soil water and rapid development of cover. Full Article
