Study on fire behavior in dry deciduous dipterocarp forest at Huai Kha Khaeng Wildlife Sanctuary, Uthai Thani Province is aimed to determine fire behavior and to find relationships between the fire behavior and some environmental factors. The results of the study will be applied to fire control and fire suppression in the area. Total twenty one burning plots with 200 m*200 m size of each were established in experimental burning site for fire behavior data collection. In addition, fuel properties and fire weather data were collected. The results revealed that averages of rate fire spread, fireline intensity and flame length were 1.89 m/min, 190 kW/m and 0.86 m, respectively. Rate of fire spread was related positively to wind velocity and fuel bed depth, but it was related negatively to moisture content of live fuel. Fire behavior was low to moderate fire intensities, that could generally be attacked at the head, flanks and rear fires by firefighters using hand tools. Hand line with at least 4 m wide could hold the fire and it should be at top alert when wind velocity was strong. Reduce the fuel bed depth and maintain high moisture content of live fuel are recommended for fuel management.
