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:
          Vegetation Hazard Class 22.1 – Melaleuca open forests on seasonally inundated lowland
           coastal swamps;
          Vegetation Hazard Class 29.2 – Woodlands associated with heathlands, scrubs and
           shrublands;
          Vegetation Hazard Class 34.5 – Sedgeland dominated wetlands; and
          Vegetation Hazard Class 39.2 – Low to moderate tree cover in built-up areas.
The characteristics of each observed vegetation hazard class are described in the following sections
whilst Plan No. BF01 – Vegetation Hazard Classes depicts their distribution across the assessment
area.

3.2.1      Vegetation Hazard Class 22.1 – Melaleuca open forests on seasonally inundated
           lowland coastal swamps
Vegetation Hazard Class 22.1 (VHC 22.1) is located in two units to the north and south of the
assessment area. The community exhibits an average canopy height of 20-25m with crown cover of
approximately 30-40%.
The canopy was dominated by Melaleuca quinquenervia (broad-leaved paperbark) but also
contained scattered Corymbia intermedia (pink bloodwood), and Acacia spp.
The mid-storey was characterised by rejuvenating paperbark, Banksia aemula (wallum banksia),
Allocasuarina littoralis (black sheoak), Glochidion sumatranum (cheese tree) and Lophostemon
confertus (brush box).
The understorey contained a mix assemblage of native grasses, shrubs and herbs and was
dominated by Blechnum indicum (bungwahl fern) in many areas.
VHC 22.1 is attributed a potential combined surface fuel load of 23.4 t/ha and a potential total fuel
load of 28.4 t/ha, and is classed as Prone Type 1 (QFES, 2019). Plate 5 depicts typical conditions
within VHC 22.1.

3.2.2      Vegetation Hazard Class 29.2 – Woodlands associated with heathlands, scrubs and
           shrublands
Vegetation Hazard Class 29.2 (VHC 29.2) is located in the southern and central extents of the
assessment area. The community exhibits an average canopy height of 10-16m with crown cover of
approximately 10-30%.
The canopy was dominated by Banksia aemula (wallum banksia) and Allocasuarina littoralis (back
she-oak). The mid-storey was characterised by rejuvenating B. aemula, Acacia spp., and
Pittosporum revolutum (forest pittosporum). The understorey is dominated by a range of native ferns,
