Current Research

My research broadly focuses on economic aspects of wildland fire and fuels management with specific research interests including: 1) wildland fire risk assessment, 2) identification of values-at-risk to wildland fire, 3) decision support system development, 4) performance measurement of wildland fire suppression, 5) modeling and forecasting of wildfire suppression costs, and 6) social and managerial tradeoffs among resources affected by fire management

Research Interests

My research interest are in exploring opportunities where economic tools can be brought to bear to improve the effectiveness and efficiency of wiland fire management programs and incident decision making.

Past Research

Currently fire mangement represents over 50 percent of the USFS budget and significantly impacts the Agency's ability to meet its core goal of caring for the land and the people. A number of challenges restrict our ability to assure that fire management investments are economically justified. Risk assessment tools present opportunities to consistently measure the current effectiveness of fire management activities and economic analysis can inform appropriate investment structures to protect both developed and highly valued natural resources.

Why This Research is Important

1. Developed the Rapid Assessment of Values At Risk (RAVAR) model, the economic impact module of the Wildland Fire Decision Support System WFDSS. 2. Authored and co-authored several papers reviewing factors influencing fire and fuels mangement costs. 3. Primary Investigator of a study that resulted in the development of valuation tools for Burned Area Emergency Response teams. 4. Investigated issues associated with the cost and efficiency of biomass utilization and associated carbon impacts.

    Mt. Jefferson, covered in snow, is highly visible behind a burned section of pine trees.
    A new tool developed through collaboration between RMRS and researchers at Oregon State University tracks treefall through time and may just save lives. Researchers found that snag hazard to fire responders decreased significantly 10-years post fire, but that in some areas, unsafe conditions could last as long as 35 years. Maps of snag hazard risk can be used by decision makers and fire responders to reduce exposure and improve the safety of wildfire response.
    Rocky Mountain Research Station scientists have developed a simulation system designed to estimate wildfire risk for Fire Planning Units (FPUs) across the conterminous United States. This research demonstrates a practical approach to using fire simulations at very broad scales for operational planning and ecological research. Findings are being used in national wildfire decision support applications such as the Forest Service and Department of Interior Hazardous Fuel Prioritization and Allocation System, and to create national maps of wildfire potential. 
    Rocky Mountain Research Station scientists affiliated with the National Fire Decision Support Center worked closely with the Agency's Western and Eastern Threat Centers to develop novel methods to assess wildfire risk to communities, watersheds, and wildlife habitat, and to developed, natural, and cultural resources. 
    The role of large airtankers (LATs) in fire suppression in the United States has been the source of debate and discussion in recent years. Using drop location data from 2010-2012 for the conterminous U.S., we linked retardant drops to fire occurrence and resource ordering records to identify whether LATs were used during initial attack, and if so, whether or not the fire was contained at the initial attack phase.
    In 2015, the cost of large fire management expenditures exceeded the allocated budget by over $700 million USD. Despite the scale of investment, little is known about how suppression resources affect large fire containment, and there remains considerable variation among fires in their relative costs. The Wildfire Risk Management Team is exploring economic issues related to cost and effectiveness of using suppression resources to manage wildland fires.
    The Wildfire Risk Management Team is an interdisciplinary team that explores wildfire management through the lenses of risk analysis, economics, decision science, and landscape ecology to improve the scientific basis for the full range of wildfire management decisions. Primary research topics include integrated spatial risk assessment modeling and planning, econometric modeling of fire management expenditures, effectiveness of suppression resource utilization, organizational structure and managerial incentive systems, and performance measurement.
