Woody biomass for bioenergy and biofuels in the United States—a briefing paper.

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.

Costs of Landscape Silviculture For Fire and Habitat Management

In forest reserves of the U.S. Pacific Northwest, management objectives include protecting late-seral habitat structure by reducing the threat of large-scale disturbances like wildfire. We simulated how altering within and among-stand structure with silvicultural treatments of differing intensity affected late-seral forest (LSF) structure and fire threat (FT) reduction over 30 years in a 6070-ha reserve. We then evaluated how different financial requirements influenced the treatment mix selected for each decade, the associated effects on FT reduction and LSF structure in the reserve, and treatment costs. Requirements for treatments to earn money (NPV+), break even (NPVO), or to not meet any financial goal at the scale of the entire reserve (landscape) affected the predicted reduction of FT and the total area of LSF structure in different ways. With or without a requirement to break even, treatments accomplished about the same landscape level of FT reduction and LSF structure. Although treatment effects were similar, their associated net revenues ranged from negative $1 million to positive $3000 over 30 years. In contrast, a requirement for landscape treatments to earn money ($0.5 to $1.5 million NPV) over the same period had a negative effect on FT reduction and carried a cost in terms of both FT reduction and LSF structure. Results suggest that the spatial scale at which silvicultural treatments were evaluated was influential because the lowest cost to the reserve objectives was accomplished by a mix of treatments that earned or lost money at the stand level but that collectivel broke even at the landscape scale. Results also indicate that the timeframe over which treatments were evaluated was important because if breaking even was required within each decade instead of cumulatively over all three, the cost in terms of FT reduction and LSF structure was similar to requiring landscape treatments to earn $0.5 million NPV.

Domestic Market Opportunities For Alaska Lumber-Species Preferences By Secondary Wood Products Manufacturers In The Continental United States.

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.

Necessary work: discovering old forests, new outlooks, and community on the H.J. Andrews Experimental Forest, 1948-2000.

The H.J. Andrews Experimental Forest (Andrews Forest) is both an idea and a particular place. It is an experimental landscape, a natural resource, and an ecosystem that has long inspired many people. On the landscape of the Andrews Forest, some of those people built the foundation for a collaborative community that fosters closer communication among the scientists and managers who struggle to understand how that ecosystem functions and to identify optimal management strategies for this and other national forest lands in the Pacific Northwest. People who worked there generated new ideas about forest ecology and related ecosystems. Working together in this place, they generated ideas, developed research proposals, and considered the implications of their work. They functioned as individuals in a science-based community that emerged and evolved over time. Individuals acted in a confluence of personalities, personal choices, and power relations. In the context of this unique landscape and serendipitous opportunities, those people created an exceptionally potent learning environment for science and management. Science, in this context, was largely a story of personalities, not simply a matter of test tubes, experimental watersheds, or top-down management sponsored by a large federal agency or university. Ideas flowed in a constructed environment that eventually linked people, place, and community with an emerging vision of ecosystem management. Drawing largely on oral history, this book explores the inner workings and structure of that science-based community. Science themes, management issues, specific research programs, the landscape itself, and the people who work there are all indispensable components of a complex web of community, the Andrews group. The first four chapters explore the origins of the Forest Service decision to establish an experimental forest in the west-central Oregon Cascades in 1948 and the people and priorities that transformed that field site into a prominent facility for interdisciplinary research in the coniferous biome of the International Biological Programme in the 1970s. Later chapters explore emerging links between long-term research and interdisciplinary science at the Andrews Forest. Those links shaped the group's response to concerns about logging in old-growth forests during the 1980s and 1990s. Concluding chapters explore how scientists in the group tried to adapt to new roles as public policy consultants in the 1990s without losing sight of the community values that they considered crucial to their earlier accomplishments.

Area-specific recreation use estimation using the national visitor use monitoring program data

Estimates of national forest recreation use are available at the national, regional, and forest levels via the USDA Forest Service National Visitor Use Monitoring (NVUM) program. In some resource planning and management applications, analysts desire recreation use estimates for subforest areas within an individual national forest or for subforest areas that combine portions of several national forests. In this research note we have detailed two approaches whereby the NVUM sampling data may be used to estimate recreation use for a subforest area within a single national forest or for a subforest area combining portions of more than one national forest. The approaches differ in their data requirements, complexity, and assumptions. In the "new forest" approach, recreation use is estimated by using NVUM data obtained only from NVUM interview sites within the area of interest. In the "all-forest information" approach, recreation use is estimated by using sample data gathered on all portions of the national forest(s) that contain the area of interest.

The LSSEs are both spatially and temporally large scale, with experimental treatment units between 5 and 100 acres and proposed study durations of 20 to 200 years. A defining characteristic of the LSSEs is that a broad range of response variables are measured to characterize the response of forest ecosystems to experimental treatments. We discuss the general value and limitations of the LSSEs and highlight some possible roles that can be played by the LSSEs in addressing management issues emerging at the beginning of the 21st century.

Taper equation and volume tables for plantation-grown red alder

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.

Water and people: challenges at the interface of symbolic and utilitarian values

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.

Evaluation of landscape alternatives for managing oak at Tenalquot Prairie, Washington

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.

Emergent lessons from a century of experience with Pacific Northwest timber markets

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.

Influence of four tree shelter types on microclimate and seedling performance of Oregon white oak and western redcedar

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.

Cooperative Alaska Forest Inventory

The Cooperative Alaska Forest Inventory (CAFI) is a comprehensive database of boreal forest conditions and dynamics in Alaska. The CAFI consists of fieldgathered information from numerous permanent sample plots distributed across interior and south-central Alaska including the Kenai Peninsula. The CAFI currently has 570 permanent sample plots on 190 sites representing a wide variety of growing conditions. New plots are being added to the inventory annually. To date, over 60 percent of the permanent sample plots have been remeasured and approximately 20 percent have been remeasured three times. Repeated periodic inventories on CAFI permanent sample plots provide valuable long-term information for modeling of forest dynamics such as growth and yield. Periodic remeasurements can also be used to test and monitor large-scale environmental and climate change.

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.

Giving credit where credit is due: increasing landowner compensation for ecosystem services.

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.

Quantifying competitive ability of perennial grasses to inhibit Scotch broom.

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.

Sage-Grouse on the edge: understanding and managing western landscapes for their survival

Scientists have had little information about how prescribed fire and cattle grazing—common practices in many Western ponderosa pine forests—affect plant abundance and reproduction in the forest understory. Pacific Northwest Research Station scientists began to explore how these practices affect vegetation in a five-year study of postfire vegetation in eastern Oregon ponderosa pine forests where cattle have been routinely pastured from late June or early July through early to mid August. For this area of eastern Oregon, they found that excluding cattle grazing during peak growing season increased native plant cover and grass flowering capability in ungrazed areas compared to grazed areas. Because vegetation was measured prior to releasing cattle on the land, the study's results tend to reflect lasting grazing impacts rather than simple consumption.

The Asian wood pellet markets.

This study examines the three major wood pellet markets in Asia: China, Japan, and South Korea. In contrast to the United States, where most wood pellets are used for residential heating with pellet stoves, a majority of the wood pellets in Asia are used for co-firing at coal-fired power plants. Our analysis indicated that Japan is the largest importer of wood pellets in Asia and that most of the pellets it consumes are used for co-firing at power plants. South Korean wood pellet imports are fairly small; however, South Korea is striving to increase its percentage of renewable energy, which could benefit the wood pellets industry. We found that China, the largest energy consumer in Asia, has an established wood pellet market. However, a majority of these wood pellets are manufactured in China, thus imports are minimal. A consistent factor in these nations is that their governments are promoting renewable energy, leading to policies that are driving demand for wood pellets. As these countries strive to meet their renewable energy targets, their wood pellet consumption is projected to grow.

Building a citizen-agency partnership among diverse interests: the Colville National Forest and Northeast Washington Forestry Coalition Experience

Concerns about forest health and the threat of wildfire across the Western United States increasingly provide the impetus for communities to find land management solutions that serve multiple interests. Funding and procedural changes over the past decade have positioned federal agencies to put greater emphasis on multistakeholder partnerships and public outreach efforts. Partnerships build slowly over time, but can result in a healthier resource, reduced fire risk, greater stability for agency planning processes, and more resilient communities. Drawing on interviews with stakeholders representing broad interests in a partnership between the Northeast Washington Forestry Coalition and the Colville National Forest, we examine some of the critical factors leading to the partnership's success and identify challenges along the way. We illustrate how the citizens of Colville, Washington, overcame conflicts by learning to communicate their interests and use existing resources to advance a variety of goals, ranging from fuels reduction and active forest management to roadless area and wilderness management. We highlight a set of important organizational themes that have emerged from Colville to provide managers and other stakeholders with ideas for similar efforts.

Precommercial thinning: implications of early results from the Tongass-Wide Young-Growth Studies experiments for deer habitat in southeast Alaska.

This report documents the results from the first “5-year” round of understory responses to the Tongass-Wide Young-Growth Studies (TWYGS) treatments, especially in relation to their effects on food resources for black-tailed deer (Odocoileus hemionus sitkensis). Responses of understory vegetation to precommercial silviculture experiments after their first 4 to 8 years posttreatment were analyzed with the Forage Resource Evaluation System for Habitat (FRESH)-Deer model. The studies were conducted in western hemlock (Tsuga heterophylla)-Sitka spruce (Picea sitchensis) young-growth forests in southeast Alaska. All four TWYGS experiments were studied: (I) planting of red alder (Alnus rubra) within 1- to 5-year-old stands; (II) precommercial thinning at narrow and wide spacings (549 and 331 trees per hectare, respectively) in 15- to 25-year-old stands; (III) precommercial thinning at medium spacing (420 trees per hectare) with and without pruning in 25- to 35-yearold stands; and (IV) precommercial thinning at wide spacing (203 trees per hectare) with and without slash treatment versus thinning by girdling in >35-year-old stands. All experiments also included untreated control stands of identical age. FRESHDeer was used to evaluate the implications for deer habitat in terms of forage resources (species-specific biomass, digestible protein, and digestible dry matter) relative to deer metabolic requirements in summer (at two levels of requirements—maintenance only vs. lactation) and in winter (at six levels of snow depth).

Estimation of national forest visitor spending averages from National Visitor Use Monitoring: round 2.

The economic linkages between national forests and surrounding communities have become increasingly important in recent years. One way national forests contribute to the economies of surrounding communities is by attracting recreation visitors who, as part of their trip, spend money in communities on the periphery of the national forest. We use survey data collected from visitors to all units in the National Forest System to estimate the average spending per trip of national forest recreation visitors engaged in various types of recreation trips and activities. Average spending of national forest visitors ranges from about $33 per party per trip for local residents on day trips to more than $983 per party per trip for visitors downhill skiing on national forest land and staying overnight in the local national forest area. We report key parameters to complete economic contribution analysis for individual national forests and for the entire National Forest System.

Tangled trends for temperate rain forests at temperatures tick up.

Climate change is altering growing conditions in the temperate rain forest region that extends from northern California to the Gulf of Alaska. Longer, warmer growing seasons are generally increasing the overall potential for forest growth in the region. However, species differ in their ability to adapt to changing conditions. For example, researchers with Pacific Northwest Research Station examined forest trends for southeastern and southcentral Alaska and found that, in 13 years, western redcedar showed a 4.2-percent increase in live-tree biomass, while shore pine showed a 4.6-percent decrease. In general, the researchers found that the amount of live-tree biomass in extensive areas of unmanaged, higher elevation forest in southern Alaska increased by as much as 8 percent over the 13-year period, contributing to significant carbon storage. Hemlock dwarf mistletoe is another species expected to fare well under warmer conditions in Alaska. Model projections indicate that habitat for this parasitic species could increase 374 to 757 percent over the next 100 years. This could temper the prospects for western hemlock—a tree species otherwise expected to do well under future climate conditions projected for southern Alaska. In coastal forests of Washington and Oregon, water availability may be a limiting factor in future productivity, with gains at higher elevations but declines at lower elevations.

Terrestrial species viability assessments for national forests in northeastern Washington.

We developed a process to address terrestrial wildlife species for which management for ecosystem diversity may be inadequate for providing ecological conditions capable of sustaining viable populations. The process includes (1) identifying species of conservation concern, (2) describing source habitats, and other important ecological factors, (3) organizing species into groups, (4) selecting surrogate species for each group, (5) developing surrogate species assessment models; (6) applying surrogate species assessment models to evaluate current and historical conditions, (7) developing conservation considerations, and (8) designing monitoring and adaptive management. Following the application of our species screening criteria, we identified 209 of 700 species as species of concern on National Forest System lands east of the Cascade Range in Washington state. We aggregated the 209 species of conservation concern into 10 families and 28 groups based primarily on their habitat associations (these are not phylogenetic families). We selected 32 primary surrogate species (78 percent birds, 17 percent mammals, 5 percent amphibians) for application in northeastern Washington, based on risk factors and ecological characteristics. Our assessment documented reductions in habitat capability across the assessment area compared to historical conditions. We combined management considerations for individual species with other surrogate species to address multiple species. This information may be used to inform land management planning efforts currently underway on the Okanogan-Wenatchee and Colville National Forests in northeastern Washington.
