Title: Demonstration Plots for Comparing Fuel Complexes and Profile Development in Untreated Stands versus Stands Treated for the Management of Spruce Beetle Outbreaks and Implications for Fuels Manipulation

Project Proposal Abstract: The activity of insects, diseases and abiotic agents is known to contribute to changes in the characteristics of fuels complexes and associated fire behavior. Landscape-scale density management strategies have been proposed as viable alternatives to sanitation or salvage for managing insect and disease outbreaks. The effect pf various density treatments on fuels complexes, or fuels development, however, is not known. An important agent of disturbance in Intermountain Region National Forests is the spruce beetle. Outbreaks have caused extensive mortality resulting in significant loss of timber, recreational opportunities and reduced aesthetics. Mortality resulting from outbreaks has also resulted in increased dead fuel loads and will likely alter the fuels complex of infested stands over time. The Fishlake National Forest in cooperation with the Utah State Division of Forestry, Fire and State Lands will implement two density management treatments in several spruce-fir forests with the purpose of reducing susceptibility of these stands to spruce beetle infestation to and enhance tree vigor. This situation provides an excellent opportunity to establish permanent demonstration plots in treated verses untreated stands. Fuels inventories and appraisals will be conducted to determine changes in the fuel complex and profile over time. Based on the fuel inventory and appraisal data fuels treatment strategies including a combination of mechanical and biomass utilization will be implemented on the demonstration plots. Prescribed fire will also be considered for treating fuel provided all prescription variables are met. Other benefits derived from this information include the demonstration of strategies for managing insect outbreaks and fuel development and manipulation.
