5.5     Assessment of fuel loads
Fuel loads for the impacting hazardous vegetation was assessed using the Overall Fuel Hazard
Guide.
Note: The fuel loads for the vegetation in the camp ground will be reduced to reflect the
discontinuous nature of the vegetation due to access tracks and campsites.

5.6     Assessment of radiant heat loads
The table below shows the expected bushfire fire line intensity in the various vegetation formations
and the distances from the vegetation to achieve a radiant heat load no greater than 2.1kW/m2.
All bushfire intensities were assessed using a Forest Fire Danger Index (FFDI) of FFDI = 50 to
maintain consistency with the A new methodology Bushfire Prone Area Mapping (Leonard et al.,
2014) which was used to derive the potential bushfire intensities shown on Figure 2 above.
