w New cost estimates for carbon sequestration through afforestation in the United States By www.fs.fed.us Published On :: Wed, 21 May 2014 9:55:00 PST This report provides new cost estimates for carbon sequestration through afforestation in the United States. We extend existing studies of carbon sequestration costs in several important ways, while ensuring the transparency of our approach. We clearly identify all components of our cost estimates so that other researchers can reconstruct our results as well as use our data for other purposes. Our cost estimates have five distinguishing features: (1) we estimate costs for each county in the contiguous United States; (2) we include afforestation of rangeland, in addition to cropland and pasture; (3) our opportunity cost estimates account for capitalized returns to future development (including associated option values) in addition to returns to agricultural production; (4) we develop a new set of forest establishment costs for each county; and (5) we incorporate data on Holdridge life zones to limit afforestation in locations where temperature and moisture availability prohibit forest growth. We find that at a carbon price of $50/ton, approximately 200 million tons of carbon would be sequestered annually through afforestation. At a price of $100/ton, an additional 100 million tons of carbon would be sequestered each year. Our estimates closely match those in earlier econometric studies for relatively low carbon prices, but diverge at higher carbon prices. Accounting for climatic constraints on forest expansion has important effects on cost estimates. Full Article

w Terrestrial species viability assessments for national forests in northeastern Washington. By www.fs.fed.us Published On :: Mon, 02 Oct 2017 9:55:00 PST 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. Full Article

w The geologic, geomorphic, and hydrologic context underlying options for long-term management of the Spirit Lake outlet near Mount St. Helens, Washington. By www.fs.fed.us Published On :: Tue, 04 Jun 2017 14:38:00 PST The 1980 eruption of Mount St. Helens produced a massive landslide and consequent pyroclastic currents, deposits of which blocked the outlet to Spirit Lake. Without an outlet, the lake began to rise, threatening a breaching of the blockage and release of a massive volume of water. To mitigate the hazard posed by the rising lake and provide an outlet, in 1984–1985 the U.S. Army Corps of Engineers bored a 2.6-km (8,500-ft) long tunnel through a bedrock ridge on the western edge of the lake.

w Life cycle assessment of wood energy for residential heating—opportunities for wood pellet production in southeast Alaska. By www.fs.fed.us Published On :: Tue, 01 Aug 2017 08:00:00 PST Southeast Alaska is a remote area, located approximately 700 miles north of Seattle, Washington. Most of the region’s goods are imported by barge, creating logistical and economic challenges not faced by many other parts of the United States. In this context, we used life cycle assessment (LCA) to evaluate the potential environmental impact on global warming potential (GWP) of converting home heating systems from heating oil to wood pellets in southeast Alaska. Once the current level (status quo) was established, we evaluated imported pellet utilization at 20-, 40- and 100-percent penetration into the residential heating oil markets. We also modeled local production of wood pellets in southeast Alaska, assuming a 20-percent penetration. Our research found that reductions in GWP resulting from the conversion to wood pellets ranged from 10 to 51 percent, with the greatest reductions being associated with the highest levels of imported pellets. The scenario of producing wood pellets in southeast Alaska to meet local needs had a reduction in GWP of 14 percent (versus the status quo). Full Article
w Gene conservation of tree species—banking on the future. Proceedings of a workshop.

w Economic Sensitivity and Risk Analysis for Small-Scale Wood Pellet Systems—an Example From Southeast Alaska. By www.fs.fed.us Published On :: Tue, 08 Aug 2017 08:00:00 PST This research models a wood pellet heating system at the Tlingit-Haida Regional Housing Authority in Juneau, Alaska, used to provide thermal energy to a 929-m2 warehouse, as an alternative to a heating system that burns more costly fossil fuels. Research objectives were to evaluate project economics of the pellet system and to conduct cost:benefit analysis on key variables (initial capital cost, fuel oil cost, and wood pellet cost). Economic results of interest included net present value, payback, internal rate of return, and cost:benefit ratio. Monte Carlo simulations were conducted using RETScreen software with the parameters of heating oil cost, wood pellet cost, fuel price escalation, and heating load. Cost:benefit analysis was conducted for capital cost versus wood fuel cost and also versus alternative fuel cost. This research found that economic performance was favorable over a wide range of normal operating conditions, even when paying a relatively high price for wood fuel. A pellet production facility in southeast Alaska could lead to lower wood fuel costs and even more favorable regional economics. Full Article

w Wood and Coal Cofiring in Alaska—Operational Considerations and Combustion Gas Effects for a Grate-Fired Power Plant. By www.fs.fed.us Published On :: Thu, 16 Feb 2018 08:00:00 PST Coal is the primary fuel source for electrical power generation in interior Alaska, with more than 600,000 tons burned annually at five different power plants. Woody biomass could be used as part of this fuel mix, offering potential environmental and economic benefits. In this research, debarked chips were cofired with locally mined coal at the Aurora Power Plant facility in downtown Fairbanks, Alaska. During two days of testing, aspen chips were successfully cofired with coal at average rates of 2.4 percent and 4.8 percent of total energy value. Combustion gases were analyzed during combustion of 100- percent coal, as well as at two different blends with aspen chips, for levels of carbon dioxide, carbon monoxide, oxygen, and nitrogen compounds. Carbon monoxide was suggested as the combustion gas most influenced by changes in woody biomass blend rate. The potential logistic and operational challenges when cofiring were also observed. Cofiring biomass at low levels in grate-combustion systems could be performed with relative ease, with only minor impacts on plant operations, including fuel storage, handling, and performance.

w Procurement Contracting In The Affected Counties of The Northwest Forest Plan: 12 Years of Change By www.fs.fed.us Published On :: Fri, 13 Jan 2006 12:00:00 PST As part of the 10-year socioeconomic monitoring of the Northwest Forest Plan, this report evaluates changes in Forest Service and Bureau of Land Management (BLM) procurement contracting between 1990 and 2002 by asking, (1) How much and what kind of work did the Forest Service and BLM contract during this period, and (2) who received economic benefits from this procurement contracting? Procurement contracting is a particular focus of the socioeconomic monitoring because one expectation of the Northwest Forest Plan was that the Forest Service and BLM would create high-skill, high-wage private sector jobs in public land restoration through contracting to partially offset job losses in timber production, harvesting, and processing. This report finds that, to the contrary, the Forest Service reduced its contracting of land management activities on national forests in the Northwest Forest Plan area from a high of $103 million in 1991 to a low of $33 million in 2002. By contrast, BLM spending was fairly constant at just under $20 million annually. Both the Forest Service and the BLM changed the type of activities that they contracted, shifting from activities associated with intensive forest management such as tree planting in clearcuts to activities associated with ecosystem management. Contractors located near national forests and BLM lands and rural communities captured a similar proportion of contracts in both the earlier and later parts of the study period. However, the significant decline in Forest Service contract spending resulted in considerable decline in the amount of money flowing to rural communities through contracting. Thus, it is unlikely that federal land management contracting created a net increase in jobs to replace jobs lost in mills and logging operations in public lands communities. Full Article

w Deep Canyon and Subalpine Riparian and Wetland Plant Associations of The Malheur, Umatilla, and Wallowa-Whitman National Forests By www.fs.fed.us Published On :: Thu, 09 Nov 2006 09:26:36 PST This guide presents a classification of the deep canyon and subalpine riparian and wetland vegetation types of the Malheur, Umatilla, and Wallowa-Whitman National Forests. A primary goal of the deep canyon and subalpine riparian and wetland classification was a seamless linkage with the midmontane northeastern Oregon riparian and wetland classification provided by Crowe and Clausnitzer in 1997. The classification is based on potential natural vegetation and follows directly from the plant association concept for riparian zones. The 95 vegetation types classified across the three national forests were organized into 16 vegetation series, and included some 45 vegetation types not previously classified for northeastern Oregon subalpine and deep canyon riparian and wetland environments. The riparian and wetland vegetation types developed for this guide were compared floristically and environmentally to riparian and wetland classifications in neighboring geographic regions. For each vegetation type, a section was included describing the occurrence#40;s#41; of the same or floristically similar vegetation types found in riparian and wetland classifications developed for neighboring geographic regions. Lastly, this guide was designed to be used in conjunction with the midmontane guide to provide a comprehensive look at the riparian and wetland vegetation of northeastern Oregon. Full Article

w Field Survey of Growth and Colonization of Nonnative Trees On Mainland Alaska By www.fs.fed.us Published On :: Mon, 17 Apr 2006 15:25:36 PST Six of nine nonnative boreal conifers in three genera (Abies, Larix, and Pinus) regenerated in 11 to 31 years after they were introduced to mainland Alaska. Lodgepole pine (Pinus contorta var. latifolia Engel.) and the Siberian larches (Larix sibirica Ledeb. and L. sukaczewii N. Dyl.) were the most widely introduced species and will likely be the first nonnative conifers to naturalize. Siberian larch grew up to six times more stem volume than white spruce in the first 40 years on upland sites, but was susceptible to the larch sawfly and a blue stain pathogen carried by bark beetles. On productive sites, lodgepole pine appeared to grow more stem wood than white spruce for about 35 years after planting. Snowshoe hares and moose were the most serious pests of the nonnative conifers. Balsam fir (Abies balsamea (L.) Mill.) was the only species to regenerate in an established moss understory. Growth and age relationships were negative for all adequately sampled nonnative conifers and positive for native white spruce (Picea glauca (Moench) Voss). Data were insufficient to assess niche availability for commercial-use of productive nonnative conifers in mixed stands in Alaska. Survey results indicate that introduction and naturalization of noninvasive tree species may improve the diversity, stability, and productivity of managed forest ecosystems. Full Article
w Assessment of The Risk of Invasion of National Forest Streams In The Pacific Northwest By Farmed Atlantic Salmon By www.fs.fed.us Published On :: Fri, 17 Nov 2006 12:00:00 PST This report describes the evidence for invasion of Pacific Northwest streams by Atlantic salmon (Salmo salar) that have escaped from marine salmon farms, and assesses the potential impact of farmed salmon invasion on native fishes inhabiting streams on National Forest System lands. The current risk to streams on National Forest lands in the Pacific Northwest from Atlantic salmon invasions appears to be low and is limited to a few areas in northwest Washington and southeast Alaska. However, long-term risks may be substantial if fish continue to escape from marine rearing pens or freshwater hatcheries. The two greatest threats appear to be that (1) Atlantic salmon could transmit a serious disease or parasite to native fishes, and (2) escaped salmon could eventually adapt to local conditions, leading to self-sustaining populations. If Atlantic salmon populations are eventually established, this species' preference for swiftly flowing stream habitats could facilitate competition with currently at-risk species such as steelhead (Oncorhynchus mykiss). This could result in a pattern of expansion similar to that observed in other nonnative aquatic plants and animals, in which a prolonged early colonization period is followed by a rapid phase of exponential growth as breeding populations adapt to local conditions.

w Toward understanding the ecological impact of transportation corridors By www.fs.fed.us Published On :: Thu, 14 Jul 2011 10:25:00 PST Transportation corridors (notably roads) affect wildlife habitat, populations, and entire ecosystems. Considerable effort has been expended to quantify direct effects of roads on wildlife populations and ecological communities and processes. Much less effort has been expended toward quantifying indirect effects. In this report, we provide a comprehensive review of road/transportation corridor ecology; in particular, how this new field of ecology has advanced worldwide. Further, we discuss how research thus far has shaped our understanding and views of the ecological implications of transportation infrastructures, and, in turn, how this has led to the current guidance, policies, and management options. We learned that the impacts of transportation infrastructures are a global issue, with the potential to affect a wide variety of taxonomically diverse species and ecosystems. Because the majority of research to date has focused on the direct and more aesthetic and anthropocentric implications of transportation corridors, mainly wildlife-vehicle collisions, it is a fairly standard practice to incorporate underpasses, green bridges (i.e., overpasses), fencing, and barriers into road corridors to alleviate such impacts. Few studies, however, have been able to demonstrate the efficiency of these structures. Furthermore, it is becoming increasingly evident that the indirect implications of transportation infrastructures (i.e., behavioral responses of wildlife individuals to roads) may be more pervasive, at least from the standpoint of biological diversity. Understanding how road corridors influence the functional connectivity of landscapes is crucial if we are to effectively manage species of concern. With these issues in mind, we propose a program of study that addresses the indirect and cumulative implications of transportation infrastructure on species distributions, community structure and ecosystem function Full Article
w Northwest Forest Plan—the first 15 years (1994–2008): status and trend of nesting habitat for the marbled murrelet By www.fs.fed.us Published On :: Mon, 29 Aug 2011 13:39:00 PST The primary objectives of the effectiveness monitoring plan for the marbled murrelet (Brachyramphus marmoratus) include mapping baseline nesting habitat (at the start of the Northwest Forest Plan [the Plan]) and estimating changes in that habitat over time. Using vegetation data derived from satellite imagery, we modeled habitat suitability by using a maximum entropy model. We used Maxent software to compute habitat suitability scores from vegetation and physiographic attributes based on comparisons of conditions at 342 sites that were occupied by marbled murrelets (equal numbers of confirmed nest sites and likely nest sites) and average conditions over all forested lands in which the murrelets occurred. We estimated 3.8 million acres of higher suitability nesting habitat over all lands in the murrelet's range in Washington, Oregon, and California at the start of the Plan (1994/96). Most (89 percent) baseline habitat on federally administered lands occurred within reserved-land allocations. A substantial amount (36 percent) of baseline habitat occurred on nonfederal lands. Over all lands, we observed a net loss of about 7 percent of higher suitability potential nesting habitat from the baseline period to 2006/07. If we focus on losses and ignore gains, we estimate a loss of about 13 percent of the higher suitability habitat present at baseline, over this same period. Fire has been the major cause of loss of nesting habitat on federal lands since the Plan was implemented; timber harvest is the primary cause of loss on nonfederal lands. We also found that murrelet population size is strongly and positively correlated with amount of nesting habitat, suggesting that conservation of remaining nesting habitat and restoration of currently unsuitable habitat is key to murrelet recovery.

By www.fs.fed.us Published On :: Mon., 15 Oct 2012 13:50:00 PST Forest managers are seeking practical guidance on how to adapt their current practices and, if necessary, their management goals, in response to climate change. Science-management collaboration was initiated on national forests in eastern Washington where resource managers showed a keen interest in science-based options for adapting to climate change at a 2-day workshop. Scientists and managers reviewed current climate change science and identified resources vulnerable to expected climate change. Vulnerabilities related to vegetation and habitat management included potential reductions in forest biodiversity and low forest resilience to changing disturbance regimes. The vulnerabilities related to aquatic and infrastructure resources included changing water quality and quantity, the risk to roads and other facilities from changes to hydrologic regimes, and the potential loss of at-risk aquatic species and habitats. Managers then worked in facilitated groups to identify adaptations that could be implemented through management and planning to reduce the vulnerability of key resources to climate change. The identified adaptations were grouped under two major headings: Increasing Ecological Resiliency to Climate Change, and Increasing Social and Economic Resiliency to Climate Change. The information generated from the science-management collaborative represents an initial and important step in identifying and prioritizing tangible steps to address climate change in forest management. Next would be the development of detailed implementation strategies that address the identified management adaptations.. Full Article
w Relations of native and exotic species 5 years after clearcutting with and without herbicide and logging debris treatments By www.fs.fed.us Published On :: Thur, 20 Dec. 2012 11:34:00 PST To increase timber production and manage other forest resource values, some land managers have undertaken logging debris and vegetation control treatments after forest harvest. We explored the roles of clearcutting on plant community composition and structure at three sites where logging debris was dispersed, piled, or removed and vegetation was annually treated or not treated with herbicides for 5 years. Without vegetation control, a competitive relation was identified between exotic and native ruderal (i.e., disturbance-associated) species. When exotic ruderal cover changed by 4 percent, native ruderal cover changed by 10 percent in the opposite direction. This relation was independent of site, but site was important in determining the overall dominance of ruderals. Five annual vegetation control treatments increased Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) growth, but decreased richness and cover of other species at the rate of one species per 10 percent reduction in cover. Debris treatment effects were small and found on only one site.

w Users Guide For FRCS: Fuel Reduction Cost Simulator Software By www.fs.fed.us Published On :: Tue, 28 Feb 2006 15:25:36 PST The Fuel Reduction Cost Simulator (FRCS) spreadsheet application is publicdomain software used to estimate costs for fuel reduction treatments involving removal of trees of mixed sizes in the form of whole trees, logs, or chips from a forest. Equipment production rates were developed from existing studies. Equipment operating cost rates are from December 2002 prices for new equipment and wage rates for the Pacific Northwest. These cost assumptions can be modified by the user. There are four ground-based systems, four cable systems, and two helicopter systems. Cost estimates are in U.S. dollars per 100 cubic feet, per green ton, and per acre. Full Article
