A New Fuel-Load Model for Eucalypt Forests in Southeast Queensland
Fires, whether wild or prescribed, exhibit a dominating influence on the Australian landscape. Land managers are required to develop and implement fire management plans in order to contend with the complex requirements of life and property protection as well the ecological needs of the fire-adapted landscape. Land managers in southeast Queensland rely upon fuel growth models and hazard assessment guides developed in other regions of Australia and the reliability of these guides has not been thoroughly tested. Fuel accumulation models are to estimate and predict fuel quantities worldwide. Linear models were developed for Eucalyptus racemosa open woodland and Eucalyptus major/Corymbia citriodora open forest types. The linear regression model suggests that time since fire, fuel depth and foliage projective cover are reliable predictors of surface fuel quantity and they can independently explain a total of 68% of the variation within the data set. The most reliable model for E. racemosa open woodland was y = (0.286) Fuel Depth + (0.321) Time Since Fire + (0.100) Foliage Projective Cover. The variation in the data also suggests that fuel is related to factors other than those measured here. Overall, this model provides useful guidance on the development of fine fuels in eucalypt forests of southeast Queensland, but more extensive testing of the model is needed.
