    <p>Abstract</p> <p>Background</p> <p>Although significant amounts of carbon may be stored in harvested wood products, the extraction of that carbon from the forest generally entails combustion of fossil fuels. The transport of timber from the forest to primary milling facilities may in particular create emissions that reduce the net sequestration value of product carbon storage. However, attempts to quantify the effects of transport on the net effects of forest management typically use relatively sparse survey data to determine transportation emission factors. We developed an approach for systematically determining transport emissions using: 1) -remotely sensed maps to estimate the spatial distribution of harvests, and 2) - industry data to determine landscape-level harvest volumes as well as the location and processing totals of individual mills. These data support spatial network analysis that can produce estimates of fossil carbon released in timber transport.</p> <p>Results</p> <p>Transport-related emissions, evaluated as a fraction of transported wood carbon at 4 points in time on a landscape in western Montana (USA), rose from 0.5% in 1988 to 1.7% in 2004 as local mills closed and spatial patterns of harvest shifted due to decreased logging on federal lands.</p> <p>Conclusion</p> <p>The apparent sensitivity of transport emissions to harvest and infrastructure patterns suggests that timber haul is a dynamic component of forest carbon management that bears further study both across regions and over time. The monitoring approach used here, which draws only from widely available monitoring data, could readily be adapted to provide current and historical estimates of transport emissions in a consistent way across large areas.</p

    Enhancing Western Managers’ Knowledge and Use of Available Economic and Financial Biomass Information and Tools

    The Joint Fire Science Program (JFSP) sponsored this study to enhance the ability of federal land managers to understand and deal with the economic and financial aspects of woody biomass removal as a component of fire hazard reduction treatments. The study objectives were to synthesize the body of economic and financial information and tools currently available to federal land managers in the West, identify managers’ information needs and disconnects from available information, and fill the gaps between existing information and tools versus managers’ awareness of available information and access to tools. The methods used for this study included 1) preparing an annotated bibliography of existing information sources and tools, 2) conducting focus groups with federal land managers throughout the West to understand their current knowledge and use of existing information and tools as well as barriers to biomass utilization, and 3) reporting study findings and distributing the bibliography in a format that provided managers with improved access to necessary and useful financial and economic information and tools. A total of 26 focus groups were conducted in six United States Forest Service (USFS) regional offices, 17 national forests, and two national parks, with a total of 97 agency personnel. On average, participants had 25 years of service with their agency and 6 years in their current position. Focus groups identified several issues and information disconnects in two major areas: the economic and financial analysis process, and the tools and information used for economic and financial analyses
