Bushfire Hazard Assessment & Management Plan v2                                                                 NCES REF: J001313

           of VHC’s1;
          Subdividing the identified vegetation hazard classes into bushfire hazard sub-units based on
           slope differences and vegetation hazard classes. All upslope and across slope vegetation
           units are allocated an underlying slope of 1 degree as per methodology prescribed within
           Queensland Fire and Emergency Services - (2019) Planning for Bushfire Resilient
           Communities. The maximal slope recorded within 25m x 25m grids within the VHC’s is
           adopted as the effective slope underlying the VHC. A conservative approach is adopted
           where multiple slopes persist within VHC’s;
          Assigning SPP Potential Bushfire Intensity classes to the sub-units;
          Application of 100m Potential Impact Buffers to the amended sub-units to derive an overall
           Local Hazard Area Map.

3.2       Vegetation Hazard Classes
The following vegetation hazard classes (classified in accordance with QFES (2019)) were identified
within the assessment area which includes a 150m buffer surrounding the site (proposed wedding
marquee and access):
          Vegetation Hazard Class 2.1 – Complex to simple, semi-deciduous mesophyll to notophyll
           vine forest;
          Vegetation Hazard Class 8.1 – Wet eucalypt tall open forest;
          Vegetation Hazard Class 9.1 – Moist to dry eucalypt open forest on coastal lowlands and
           ranges;
          Vegetation Hazard Class 24.1 – Acacia open forest on residuals;
          Vegetation Hazard Class 36.1 – Exotic & hardwood plantations;
          Vegetation Hazard Class 38.4 – Continuous dryland cropping and horticulture;
          Vegetation Hazard Class 39.2 – Low to moderate tree cover in built-up areas;
          Vegetation Hazard Class 40.4 – Continuous low grass or tree cover; and
          Vegetation Hazard Class 43.6 – Water bodies or very low vegetation cover.
The characteristics of each observed vegetation hazard class are described in Appendix 2 whilst
Plas BF01a and Plas BF01b – Vegetation Hazard Classes depicts their distribution across the
assessment area.

  The patch and corridor filtering process to remove or downgrade hazard levels of small patches and narrow corridors involves the
following three stages:
          Merging small patches of a single Vegetation Hazard Class less than 0.5 ha;
          Merging small Vegetation Hazard Class patches between 0.5 and 1 ha with higher or moderate fuel loads (greater than 8
           tonnes/ha); and
          Removing narrow corridors of vegetation less than 50m wide through a process of patch erosion and dilation. These small
           patches are merged with surrounding vegetation by allocating a patch to the Vegetation Hazard Class that is most common to
           the patch boundary (Leonard et al., 2017).
