Wood and Coal Cofiring In Interior Alaska: Utilizing Woody Biomass From Wildland Defensible-Space Fire Treatments and Other Sources

Cofiring wood and coal at Fairbanks, Alaska, area electrical generation facilities represents an opportunity to use woody biomass from clearings within the borough's wildland-urban interface and from other sources, such as sawmill residues and woody material intended for landfills. Potential benefits of cofiring include air quality improvements, reduced greenhouse gas emissions, market and employment development opportunities, and reduction of municipal wood residues at area landfills. Important issues that must be addressed to enable cofiring include wood chip uniformity and quality, fuel mixing procedures, transportation and wood chip processing costs, infrastructure requirements, and long-term biomass supply. Additional steps in implementing successful cofiring programs could include test burns, an assessment of area biomass supply and treatment needs, and a detailed economic and technical feasibility study. Although Fairbanks North Star Borough is well positioned to use biomass for cofiring at coal burning facilities, long-term cofiring operations would require expansion of biomass sources beyond defensible-space-related clearings alone. Long-term sources could potentially include a range of woody materials including forest harvesting residues, sawmill residues, and municipal wastes.

National forests on the edge: development pressures on America's national forests and grasslands

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.

Regional Cost Information For Private Timberland Conversion and Management

Cost of private timber management practices in the United States are identified, and their relationship to timber production in general is highlighted. Costs across timber-producing regions and forest types are identified by forest type and timber management practices historically applied in each region. This includes cost estimates for activities such as forest establishment practices such as reforestation and afforestation on crop and pastureland. Establishment costs for reforestation in the Southern United States are less than in other regions, although regional differences in establishment costs are less evident in hardwood than in softwood stands. Also, included in the list of timber management costs ate the intermediate management treatments of precommercial thinning, herbicide, and fertilizer application. Intermediate management treatments are less costly in the southern United States than in other regions. Trends in timber management costs reported as part of the management costs reporting.

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

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.

Linking Land-Use Projections and Forest Fragmentation Analysis

An econometric model of private land-use decisions is used to project land use to 2030 for each county in the continental United States. On a national scale, forest area is projected to increase overall between 0.1 and 0.2 percent per year between now and 2030. However, forest area is projected to decrease in a majority of regions, including the key forestry regions of the South and the Pacific Northwest Westside. Urban area is projected to increase by 68 million acres, and cropland, pasture, rangeland, and Conservation Reserve Program land is projected to decline in area. Regional econometric models are needed to better represent region-specific economic relationships. County-level models of forest fragmentation indices are estimated for the Western United States. The core forest model is found to perform better than the model of like adjacencies for forest land. A spatially detailed analysis of forest fragmentation in Polk County, Oregon, reveals that forests become more fragmented even though forest area increases. By linking the land-use projection and forest fragmentation models, we project increases in the average county shares of core forest in 8 of the 11 Western States. The average like adjacency measure increases in six of the states. The aggregate and spatially detailed fragmentation methods are compared by projecting the fragmentation indices to 2022 for Polk County, Oregon. Considerable differences in the results were produced with the two methods, especially in the case of the like adjacency metric.

Evaluating Forest Land Development Effects On Private Forestry In Eastern Oregon

Research suggests that forest land development can reduce the productivity of remaining forest land because private forest owners reduce their investments in forest management. We developed empirical models describing forest stocking, thinning, harvest, and postharvest tree planting in eastern Oregon, as functions of stand and site characteristics, ownership, and building densities. The models are based on USDA Forest Service Forest Inventory and Analysis data gathered in eastern Oregon in 1987 and 1998, and data describing building densities gathered by the Oregon Department of Forestry from aerial photographs taken over the same period. We used the models to examine the potential effects of population growth and development, as described by increasing building densities, on the likelihood that private forest owners maintain forest stocking, precommercially thin, harvest, and plant trees following harvest. Empirical results suggest that population growth and development have had no measurable effect on these activities in eastern Oregon during the period examined. Any development effects on private forest management and investment so far are likely to be fairly localized.

An assessment of frameworks useful for public land recreation planning.

Public land managers are confronted with an ever-growing and diversifying set of demands for providing recreation opportunities. Coupled with a variety of trends (devolution of governance and decisionmaking, population growth, technological innovation, shifts in public values, economic restructuring) and reduced organizational capacity, these demands represent a significant and complex challenge to public land management. One way of dealing with this situation is to use a framework to assist in working through this complexity. A framework, for the purpose of this report, is a process using a set of steps, based on sound science, that assists managers in framing a particular problem, working through it, and arriving at a set of defendable decisions. Several such frameworks exist for providing recreation opportunities on public lands. These include the Recreation Opportunity Spectrum, Limits of Acceptable Change, Visitor Experience and Resource Protection, Visitor Impact Management, and Benefits-Based Management. The report traces the development of each of these frameworks, describes the fundamental premises and concepts used within them, and provides an assessment of the experience with their use. Each of the frameworks has been used with varying success, depending on the organization's will, its technical capacity, the extent to which the process is inclusive of varying value systems, how open and deliberative the process is, the extent to which the organization is concerned with effectiveness, and the extent to which issues are confronted at the systems level.

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.

A protocol using coho salmon to monitor Tongass National Forest Land and Resource Management Plan standards and guidelines for fish habitat

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.

Calibration and modification for the Pacific Northwest of the New Zealand Douglas-fir silvicultural growth model

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.

Ecological foundations for fire management in North American forest and shrubland ecosystems

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.

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.
