A century of fire suppression has created heavy fuel loads in many U.S. forests, leading to increasingly intense wildfires. Addressing this problem will require widespread fuels treatments, yet fuels treatment planners do not always have access to the current scientific information that can help guide their planning process. The Fuels Planning: Science Synthesis and Integration project was launched to compile relevant fuels treatment information for managers. Products include syntheses on various topics, a guidebook on silvicultural prescriptions, a set of models and information databases on possible environmental effects of fuels treatments, and a financial analysis tool for estimating costs and revenues of fuels treatments. The Fuels Planning project provides an example of how collaboration between managers and scientists can improve the utility of scientific findings. It is currently forming partnerships with several National Environmental Policy Act (NEPA) interdisciplinary teams who will use these decision support tools in planning fuels reduction projects starting in the summer of 2005.
