Current Research

Much of my current research focuses on better understanding the relationship between climate and wildfire, and how this relationship might shift with climate change. In addition, I am interested in how spatial planning can be utilized to inform fire and landscape management options.

    Forest plot data is matched to gridded landscape data from LANDFIRE using the random forests method. The output consists of a grid of the IDs for the best-matching plot for each pixel.
    https://www.treesearch.fs.fed.us/pubs/53114Maps of the number, size, and species of trees in forests across the western United States are desirable for a number of applications including estimating terrestrial carbon resources, tree mortality following wildfires, and for forest inventory. However, detailed mapping of trees for large areas is not feasible with current technologies. We used a statistical method called random forests for matching forest plot data with biophysical characteristics of the landscape in order to populate entire landscapes with a limited set of forest plot inventory data. 
    The RMRS Wildfire Risk Management Team has been instrumental in the development and maintenance of national fire and vegetation datasets that are foundational to U.S. wildfire risk science. The assessment of contemporary wildfire hazard--a fundamental part of the risk assessment framework--is not possible without a reliable source of historical fire-occurrence data.
    Effective and efficient risk based management requires integrated knowledge, systems and planning tools that explore the interaction of the full range of land and fire management activities. The Wildfire Risk Management Team is working with managers to develop and demonstrate the power of integrating fire-risk science across the full range of fire management activities from local to national scales. Improved linkages between landscape fire potential and land management objectives will have profound effects on the efficiency of the full range of fire management activities. 
    Effective and efficient risk-based management requires integrated knowledge, systems and planning tools that explore the interaction of the full range of land and fire management activities. The Wildfire Risk Management team is working to develop and demonstrate the power of integrating fire-risk science across the full range of fire management activities. This work will include the first pilot study of changes in wildfire risk across time, using the prototype LANDFIRE time series dataset, created specifically for the study landscape.
    How is drought affecting the forests and rangelands of the United States? Dr. Karin L. Riley, Research Ecologist with the Human Dimensions program of the USDA Forest Service Rocky Mountain Research Station, participated in a recent effort to synthesize the current science on this topic, along with 76 other scientists from federal land management agencies, universities, and other research institutions.
    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.
