Wildfires account for a lot of property damage every year in the US, and forestry officials are constantly assessing how to predict when and where they will occur. One researcher says a largely overlooked predictor is the human factor. Brian Bull reports:
Generally, vegetation and terrain are examined to figure out fire-prone areas. But Alexandra Syphard, a University of Wisconsin researcher, says most blazes happen along developments or roads, where forestland borders urban areas. Syphard says while she used southern California for her research model, her findings can be applied anywhere there is natural terrain along with man-made roads and structures.
“While the variables may differ a little bit in their degree of influence in different regions, you can still use these same kinds of methods to account for all of the factors that influence fires, as opposed to what a lot of people commonly do which is just simply looking at areas where fuels have accumulated.”
Syphard presented her research at the Third International Fire Ecology and Management Congress. She says variables such as terrain, climate, and vegetation still figure largely in active burns but that the human factor needs to be reviewed more closely.
