If it is possible to know under what conditions a forest fire result in a moderate behavior, then it could be used in a controlled way to achieve specific goals. Accordingly, this study monitored how environmental factors influence fire behavior, when a prescribed burn was applied in a pine-oak forest stand. The parameters of fire behavior evaluated were rate of spread, flame height and flame length. In relation to the factors that influence fire behavior, burn elapsed time, relative humidity, wind speed and temperature were evaluated. It was concluded that relative humidity had a major influence on fire behavior. However, at times flame height and length showed erratic behavior in relation to relative humidity, which could be caused by variations in fuel availability and continuity. In general, an increase in temperature was associated with a decrease in relative humidity. This integration clearly influences the first stage of the burn. However, due to low wind speed, this factor had no significant influence.

Palabras llave : flame height; flame length; rate of fire spread; forest fuels.
