Project Objectives: We request support from the JFSP to: 1. adapt FFE-FVS to support fire-related economic analysis by linking FFE-FVS to IASELECT (Wiitala 1992) and CHEAPOII (Horn and others 1986). IASELECT quantifies the optimal economic performance of a fire organization in suppressing a site specific fire contained by initial attack. CHEAPOII provides routine economic analyses (such as cost benefit analysis) given costs of accomplishing treatments and revenue of the resulting product flow. Modification of this model will require the addition of fire-related treatment costs to the existing model. 2. Format fuel output so that predicted future fuel loadings can be used in emissions source strength models (like the Emissions Production Model). This will allow explicit evaluation of forest management actions based on simulated emissions at various points in the future, as fuels continue to accumulate and decay. FFE-FVS already predicts total smoke production if a prescribed fire or wildfire is simulated. 3. Modify the FFE-FVS to produce data required as input by FARSITE (1998) at chosen time intervals, and to receive fire occurrence information from FARSITE. This will allow landscape level assessments of fuel treatments by providing a means to simulate outcomes of treating fuels in some stands and not others, treating at different times, or both. Outputs will include a full array of fire effects and subsequent forest structure, function, and composition. Since FFE-FVS tracks surface and crown fuels over time, this will require only minor modifications to the program.
