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 3.1 – Notophyll vine forest;
      •    Vegetation Hazard Class 24.1 – Acacia open forest on residuals;
      •    Vegetation Hazard Class 39.2 - Low to moderate tree cover in built-up areas; and
      •    Vegetation Hazard Class 40.4 – Continuous low grass or tree cover.
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 3.1 – Notophyll vine forest
Vegetation Hazard Class 3.1 (VHC 3.1) is the dominant vegetation type within the site and offsite to
the northeast. The community exhibits an average canopy height of 16-22m with crown cover of
approximately 40-80%.
The canopy is dominated by Acacia concurrens (black wattle) and Acacia disparrima (hickory wattle)
but also contained Jagera pseudorhus (foambark), Macaranga tanarius, Guioa semiglauca (wild
quince), Flindersia schottiana (bumpy ash cudgerie), and Glochidion sumatranum (cheese tree).
The mid-storey contained a mix assemblage of Alphitonia excelsa (soap tree), Polyscias elegans
(celery wood), Alphitonia petriei (white ash), Mallotus claoxyloides (green kamala), and
Cinnamomum camphora (camphor laurel).
The understorey in the eastern site extent was almost dominated by a monoculture of Lantana
camara with Smilax australis (barbwire vine) and Solanum mauritianum (tobacco bush) also present.
Whereas the balance VC1 exhibited an understorey dominated by Pteridium esculentum (bracken
fern) in the gully with Smilax australis (barbwire vine), Cordyline rubra (cordyline lily), and scattered
Cinnamomum camphora and Lantana camara also present.
VHC 3.1 is attributed a potential combined surface fuel load of 4.5 t/ha and a potential total fuel load
of 12.0 t/ha (QFES, 2019). It should be noted that Rainforest vegetation is a low hazardous
vegetation type and is not assessable under the SPP 2019. Plate 5 depicts typical conditions within
VHC 3.1.

3.2.2      Vegetation Hazard Class 24.1 – Acacia open forest on residuals
Vegetation Hazard Class 24.1 (VHC 24.1) is the dominant vegetation type in the south and western
limits of the assessment area. The community exhibits an average canopy height of 10-15m with
crown cover of approximately 30-40%.
The canopy is dominated by a monoculture of Acacia melanoxylon (blackwood) but also contained
scattered regrowth rainforest species found in VHC 3.1 and low density of Eucalyptus tereticornis
