Fuel Loads, Fire Behavior, and Emissions
Studying predictors of forest fuel loading, fuel consumption, and fire behavior is key to understanding natural fire regimes, predicting wildfire danger, and estimating smoke and particulate matter produced by burning under different conditions. Research in the Fire Ecology Program has focused on the effects of fire frequency, management history, and pine tree stocking on these factors in southeastern U.S. pinelands. One area of focus in collaboration with Florida A&M University has been improved estimation of emission factors for particulate matter (PM, or smoke particles). Emission factors predict the amount of pollutant produced per fuel consumed are important for regional and national emissions inventories and development of air quality policy. Research findings and data are provided to agencies that develop user-friendly computer models that predict fuel loads, fire behavior, and smoke emissions to assist in fire management planning and incident response. These data are also important for understanding plant productivity and carbon cycling on pineland landscapes.
