The relationship between woody fuel consumption and fireline intensity was assessed using data collected at controlled fires and wildfires in south-western Western Australia, central Victoria and south-eastern New South Wales. The combined dataset consisted of fires in a range of dry eucalypt forests. Fire behaviour varied from slow, self-extinguishing prescribed bums to intense, fastmoving fires burning under conditions of extreme fire danger. Fire line intensity ranged from 50 kW m-1 to > 31 000 kW m-1 • Woody fuel consumption ranged from 31% to I 00%, and generally increased with fire intensity. Percentage consumption was highest for small woody fuels where the diameter was between 0.6 em and 2.5 em. Fireline intensity had a statistically significant, positive relationship with the proportion of woody fuel consumed by both controlled fires and wildfires. Two generalised linear models (GLM) describing woody fuel consumption as a function of fire line intensity were developed, one applicable to the prescribed fire environment (with fire line intensities typically< 750 kW m-1 ) and the other to the full range of fire line intensities. The prescribed burning model produced the best fit and lowest error statistics.
