2.3.1    Vegetation Hazard Class 3.1 – Notophyll vine forest
Vegetation Hazard Class 3.1 (VHC 3.1) is present within the north-west and eastern extent of the
site and located offsite to the south and north. The vegetation generally consists of early phase
regrowth and has attained an average height of 20m. The canopy is dominated by Acacia
melanoxylon (black wattle), Commersonia bartramia (brown kurrajong), Flindersia schottiana
(bumpy ash) and Alphitonia excelsa (red ash). Crown cover percentage is approximately 60% with
the majority of canopy trees attaining an average diameter at breast height (DBH) of approximately
150-200mm.
The mid-storey is mid-dense and contains sub-adult canopy species and additional species such as
Litsea leefeana (brown bolly gum), Guioa semiglauca (native quince), Acacia disparrima (hickory
wattle), Ficus fraseri (sandpaper fig) and the invasive species Cinnamomum camphora (Camphor
laurel).
The understorey is highly degraded and dominated by the invasive species Lantana camara
(lantana).
VHC 3.1 is attributed a potential combined surface fuel load of 4.4t/ha and a potential total fuel load
of 4.4t/ha (QFES, 2019). Plate 4 depicts typical conditions within VHC 3.1.

2.3.2    Vegetation Hazard Class 9.1 – Moist to dry Eucalypt open forests on coastal lowlands
         and ranges
Vegetation Hazard Class 9.1 (VHC 9.1) is present offsite to the west of Black Mountain Range Road.
The upper canopy has attained an average height of 40m and is dominated by Eucalyptus grandis
(flooded gum). Corymbia intermedia (pink bloodwood) and Lophostemon confertus (brushbox) were
also observed within the canopy, having a sub-dominant presence. Crown cover percentage is
approximately 40% with the majority of flooded gums reaching an average diameter at breast height
(DBH) of approximately 500mm.
The mid-storey is sparse and is dominated by Acacia melanoxylon (black wattle), Commersonia
bartramia (brown kurrajong), Flindersia schottiana (bumpy ash) and Alphitonia excelsa (red ash).
The understorey is moderately degraded and includes native and exotic grasses, and ferns such as
Pteridium esculentum (bracken fern).
VHC 9.1 is attributed a potential combined surface fuel load of 21t/ha and a potential total fuel load
of 24.2t/ha (QFES, 2019). Plate 5 depicts typical conditions within VHC 9.1.
