            table also presents the hazard scores for a range of vegetation communities. Vegetation
            community data is available in digital map form from the Queensland l-ierbarium,
            Environmental Protection Agency, at a scale of 1: 100,000.

              Note 1: Vegetation assessment should he based upon examination of the vegetation on the subject site and
              surrounding the subject site. :Narrow strips of vegetation may be/latnmable; however, bush f res will not
              ,generally reach their !dl intensity where bushfire fronts are less than /00 metres wide. For this reason
              due following examples may be viewed as having the new lower hazard score (i.e. paperbark heath would
              have a score of h not 8, cypress pine forest 5 not 6):
               •   areas with a linear shape (e.g roadside vegetation beside a cleared paddock): and
               •   writs of vegetation less than 50 hectares in area and more than one kilometre from the nearest
                   extensive vegetation.



     A3.14 Where the vegetation community is assessed as having a vegetation community hazard
           score of zero, no other factors need to be taken into account and the relevant sub-units
           should be given a Low severity of overall bushfirc hazard. No further action is required.
