4.2       Vegetation Hazard Classes (VHC’s)
The vegetation which contributes to bushfire hazard is classified into Vegetation Hazard Classes
(VHC’s) according to a modified version of Queensland’s broad vegetation groups. VHC’s are
assigned a prone type, which is a categorical indicator of the status of a VHC with respect to its
capacity to support a significant bushfire. The prone type categories are:
• Forest or Shrub fires (1)
• Grassland fires (2)
• Low hazard (3).
The following vegetation hazard classes were identified within the 150 m assessment area:
      •    9.1 Moist to dry eucalypt open forests on coastal lowlands and ranges (Prone Type 1)
      •    22.1 Melaleuca open forests on seasonally inundated lowland coastal swamps (Prone Type
           1)
      •    41.4 Low grass or tree cover in built-up area (Prone Type 3) ;
      •    42.6 Nil to very low vegetation cover (Prone Type 3); and
      •    43.6 Water bodies or very low vegetation cover
The characteristics of the identified vegetation hazard classes are described in Appendix 2.
No woody vegetation clearing is proposed under the application hence the extent and composition
of observed pre-development VHCs is not expected to change post development. Preparation of a
post development VHC map was therefore deemed unnecessary.
The distribution of VHCs across the assessment area is described on:
      •    Plan BF01 –Vegetation Hazard Classes.
The extent of vegetation depicted in BF01 has been utilised to formulate the Local Hazard Maps
presented herein.
