The Interagency Fuel Treatment Decision Support System (IFTDSS, https://iftdss.firenet.gov/) can be used to evaluate fuel treatment scenarios and their thresholds to effectiveness. For this project, we developed a potential fuel treatment layer based on vegetation type, topography and aspect class that can used for landscape evaluations of fuel treatment strategies. We focused on two priority landscapes identified within the 20-year Forest Health Strategic Plan for eastern Washington State, including Methow Valley and Republic (https://www.dnr.wa.gov/publications/rp_forest_health_20_year_strategic_plan.pdf). Strategic fuel treatment layers were created by classifying the LANDFIRE Biophysical Settings (BPS) layer into units with the same vegetation type, topographic position, and aspect classes. Because our study areas are dominated by low elevation mixed conifer forests, we applied a consistent fuel reduction treatment (forest thinning followed by a combination of pile burning and prescribed underburning) to randomly selected treatment units across scenario landscapes, ranging in treatment intensity from 10% to 60%.
