Reference Sites: 12 Quaternary
Vegetation Community 5b: Vegetation Community 5b is the dominant woodland an open forest
community on Moa Island where it occupies silty alluvial outwash plains and piedmont fans,
typically derived from granite, hornfels and metamorphic lithologies. The community is mapped
as the newly described RE subtype 3.3.20c which is represented as a woodland to open forest,
with canopy heights ranging from 18 to 27m. Corymbia clarksoniana tends to dominate the
canopy, although associated canopy species may include Corymbia nesophila, Corymbia
tessellaris, Corymbia stockeri subsp. peninsularis and Welchiodendron longivalve.
Welchiodendron is often well represented in the canopy and shrub layers which may also
