6.2     Derivation of inputs for assessment of the Potential Bushfire Intensity Class
The assessment of the Potential Bushfire Intensity Class using the protocol of A new methodology
for state-wide mapping of bushfire prone areas (Leonard et al, 2014) requires the following inputs.
Potential Fuel Load
Based on the map of the visually assessed vegetation communities shown in Figure 7 above, the
Potential Fuel Loads can be derived by relating the assessed vegetation to Table 1: Vegetation
Hazard Classes (VHC) and associated Potential Fuel Loads in Risk and Resilience Technical
Manual: A ‘fit for purpose’ approach in undertaking natural hazard studies and risk assessments

Table 3: Potential fuel loads for the assessed vegetation communities based on their applicable
potential fuel hazard classes

 Eucalyptus spp tall open forest           9.1 Moist to dry eucalypt open forests          24.1 t/ha
                                              on coastal lowlands and ranges

      Rural residential lots with           40.4 Low grass or tree cover in rural            5 t/ha
      gardens, mown grass etc                             areas


Fire Weather Severity
The applicable Fire Weather Severity for the subject lot was drawn from the map of Queensland
Fire Weather Severities on Figure 16: Fire weather severity for Queensland in Leonard et al
(2014), page 17.
The applicable Fire Weather severity for the subject area = FDI 50
