2.3.2    Vegetation Hazard Class 39.2 – Low to moderate tree cover in built up areas
Vegetation Hazard Class 39.2 (VHC 39.2) occurs adjacent to the existing residence and surrounding
areas of moderate tree cover, typically with a cleared or mown understorey. Common canopy
species include E. racemosa (scribbly gum) and M. quinquenervia (broad leaved paperbark), L.
suaveolens (swamp brushbox), Eucalyptus latisinensis (white mahogany), Angophora leiocarpa
(rusty gum) and Pinus elliottii (slash pine).
In open areas the mid-storey is typically void due to past clearing with A. melanoxylon (blackwood)
and Glochidion ferdinandi (cheese tree) occurring at low densities. The understory is comprised of
a mix of mown grass species.
VHC 39.2 is attributed a potential combined surface fuel load of 5 t/ha and a potential total fuel load
of 8 t/ha (QFES 2019). VHC 39.2 is assigned a Low Potential Bushfire Intensity class on flat ground
(Leonard et al., 2017).

2.3.3    Vegetation Hazard Class 41.4 – Discontinuous low grass or tree cover
Vegetation Hazard Class 41.4 (VHC 41.4) occurs in the north east of the site and dominates the
lands immediately to the north and east of the site where a low density tree cover is present. This
VHC primarily consists of landscaped gardens and open paddocks with low density native trees and
regularly mown grass areas.
VHC 41.4 is attributed a potential total fuel load of 2 t/ha and a potential combined surface fuel load
of 2 t/ha (QFES, 2019). VHC 41.4 is assigned a Low Potential Bushfire Intensity class on flat ground
(Leonard et al., 2017).
