Watershed Scale Wildfire Risk Characterization and Mitigation in the Big Thompson Basin

Abstract: This executive summary examines wildfire risk dynamics, human dimensions of natural resource planning, and mitigation strategies within Colorado's 78 mile Big Thompson watershed. Integrating research from Colorado State University’s Department of Human Dimensions of Natural Resources, the report details the ecological and public health consequences of wildland urban interface (WUI) fires, notably severe air quality degradation from fine particulate matter (PM2.5) and drinking water catchment contamination. Using the Wildfire Action Plan (WARP) risk assessment matrix spanning hazard identification, exposure calculation, and fuel toxicity remediation the study provides actionable recommendations, including defensible space vegetation management, automated air/water quality monitoring, community protective resources, and legal liability enforcement for anthropogenic ignitions.
