The interaction between wildfire and human development is one example of a coupled human natural system where human activities affect patterns of fires and fires presents risks to society. This research asked (1) how does development interact with fire?, (2) where are homes at risk from fires?, and (3) where can fires burn without risk? First, I quantified detection rates of active fire detections from the Terra and Aqua MODIS satellite sensors from 2000 to 2006 with a set of reference fire perimeters. Second, I quantified patterns of fire occurrence using the MODIS fires. Third, I evaluated the relative importance of vegetation, climate, topography, and human variables in predictive models of fire occurrence. Finally, I used the fire occurrence models to quantify risk to homes in the U.S. and identify areas where fires can burn without risk. The MODIS fires captured most reference fires, especially large fires relevant for understanding fire occurrence and risk. Between 2003 and 2006, 1.24% of the U.S. and 1,000,000 housing units experienced MODIS fires each year. However, fires were considerably larger in the West than in the East. Human variables had strong influences determining patterns of fire occurrence, which were independent from the effects of vegetation, climate, and topography and exhibited non-linear responses in many ecoregions. When predicted fire occurrence was used to estimate risk, I found that 3,700,000 homes were spread over 403,000 km2 and had a 1% probability of fire occurrence. However, when only large fires were considered there were only 402,000 homes spread over 8,400 km2 with 1% probability of fire. Potential for fire use is high for 44% of the U.S. and 1,500,000 km2 have high fire use potential and are free of homes. Human development introduces novel disturbance patterns and acts as an external driver of ecosystem change. Fires have reciprocal effects on adjacent development and present significant risk to human values. Development and fire are inextricably linked, and development in fire-prone landscapes will continue. Consequently, ecosystem and fire management will be continually challenged by development and solutions are needed that better integrate communities with ecosystem dynamics.
