3.2.4    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 a small linear unit in the northwest site extent.
The vegetation community exhibits an average canopy height of 12m. The unit exhibited a
monoculture of Melaleuca quinquenervia (broad-leaved paperbark) at a thickness of 2-3 trees. The
understorey contained unmanaged grass.
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 classified as Prone Type 1 (QFES, 2019). Plate 5 depicts typical conditions
within VHC 22.1.

3.2.5    Vegetation Hazard Class 24.1 – Acacia open forest on residuals
Vegetation Hazard Class 24.1 (VHC 24.1) is located in a single unit in the northeast of the site. The
community exhibits an average canopy height of 20m with crown cover of approximately 20-30%.
The canopy exhibited a monoculture of Acacia disparrima (hickory wattle). The mid-storey was
characterised by rejuvenating wattle, Glochidion ferdinandi (cheese tree), Flindersia schottiana
(bumpy ash), Heptapleurum actinophyllum (umbrella tree), and Macaranga tanarius (macaranga).
While the understorey was dominated by weed species Bidens Pilosa (cobblers pegs), Lantana
camara (lantana), and Ageratum houstonianum (blue billy goat weed), with Parsonsia straminea
(monkey rope) also present.
VHC 24.1 is attributed a potential combined surface fuel load of 9.5 t/ha and a potential total fuel
load of 10.1 t/ha, and is classified as Prone Type 1 (QFES, 2019). Plate 9 depicts typical conditions
within VHC 24.1.
