Text Appearing Before Image:
NEW MODEL PREDICTS SPOT FIRE DISTANCE Flying sparks or embers sometimes cause spot fires beyond the advancing front of a main fire. Fire spread by spotting is a chance event requiring the right combination of fuels, wind, and foliage moisture. When spot fires do occur, they complicate the task of wildfire control and sometimes cause prescribed fires to escape their intended boundaries. Inability to predict spotting severity increases the danger to f irefighting crews and increases the chance of failure in planned fire management activities. A new model developed by scientists at the Intermountain Forest and Range Experiment Station can help fire managers answer some of their questions about spotting. The model predicts the maximum spot fire distance that can be expected from a burning tree or small group of trees. The predicted spotting distance depends on tree species and size, windspeed, and downwind terrain. The algorithm for estimating spotting distance can be solved using a graphic procedure or a programable handheld calculator. Although many questions remain unanswered, experience with this new model should help fire researchers and managers better understand and cope with spot fires.
