    Climate change studies suggest that extreme wildfires will become more frequent in the future. We investigated the prediction of extreme wildfire events - plausible but rare scenarios that describe yet to be observed fire disasters - using fire simulation methods.

    We integrated the widely used Forest Vegetation Simulator with FSim, a large wildfire simulator, to study how management policies affect future wildfire regimes. The model leverages decades of research and development on the respective forest growth and wildfire simulation models, and their integration creates a strategic forest landscape model that can be used to examine forest fire and management policy issues on National Forests in the western United States.

    The USDA Forest Service Rocky Mountain Research Station recently released a new General Technical Report, GTR-392, Cross-boundary Wildfire and Community Exposure: A Framework and Application in the Western US. The publication describes the development and application of a framework to assess cross-boundary wildfire exposure for the Western U.S. with the purpose of mapping potential fire transmission among public and private lands, and identifying areas where ignitions are most likely to expose communities to wildfire.  
    ForSys is a flexible platform for exploring landscape management scenarios and optimizing decisions in terms of where and how to achieve landscape restoration and fuel management goals. The model is spatially explicit and uses multi-criteria prioritization and optimization created to rapidly design fuel treatment and restoration scenarios. The program evolved from the Landscape Treatment Designer used in prior studies.
    The USDA Forest Service Scenario Investment Planning Platform was developed by Forest Service Research & Development to help the agency modernize its approach to prioritizing land management investments. 
    Firesheds are a way to delineate where fires ignite and are likely to, or not to, spread to communities and expose buildings. The fireshed map shows the source of exposure to fire. The fireshed registry is the geospatial portal that portrays the past, present, and future in terms of agency investments in forest and fuel management in relation to historical and predicted fire activity.   
    ArcFuels was built to streamline the fuel management planning process, and provide tools for quantitative wildfire risk assessment.
    We integrated the widely used Forest Vegetation Simulator with FSim, a large wildfire simulator to study how management policies affect future wildfire regimes.  The model leverages decades of research and development on the respective forest growth and wildfire simulation models, and their integration creates a strategic forest landscape model that has a high degree of transparency in the existing user communities.  We are using the model to examine forest fire and management policy issues on national forests in the western US.
    We are using the agent-based landscape simulation model Envision to explore a wide range of forest management and future wildfire scenarios to understand how accelerated restoration programs and climate change might alter forest trajectories over time. We are particularly interested in landscape tipping points, feedbacks, and synergies between wildfire and restorative forest and fuels management. We are measuring a wide range of response variables including landscape carbon, spatial pattern and patch size of high severity fire, and resilient forest. The modeling work is being conducted with study areas in central Oregon that encompass 3 million ha of federal and private forest lands. 
    This project investigated the issue of radionuclide resuspension from wildland fires in areas contaminated by the Chernobyl nuclear power plant explosion. The work was originated from a scientific exchange among scientists from the USDA Forest Service, Ukraine and Belarus that was organized by USFS International Programs to assess science and technology gaps related to wildfire risk management.  One of the products from that exchange was the development and application of a wildfire risk modeling system to predict likely hotspots for large fires and where wildfire ignitions will most likely result in significant radionuclide (Cesium, 137Cs) resuspension. The system was also used to identify locations for ignition prevention and strategic fuel breaks to reduce future emissions.  
    In this project we provide the first comprehensive assessment of where public wildlands in the western United States potentially contribute wildfire exposure to communities in the 11 western states and provide a framework for assessing cross-boundary wildfire exposure.
