2.2. Regional Ecosystems
The rehabilitation area is primarily mapped as non-remnant vegetation. One small pocket of Regional
Ecosystem (RE) 12.3.1a is present in the south-western part of the rehabilitation area. Pre-clearance
RE mapping identifies the rehabilitation area as previously containing RE 12.3.11 and 12.3.2.
RE 12.3.1a:
Gallery rainforest (complex to simple notophyll vine forest) on alluvial plains; classed as endangered
under the Vegetation Management Act. Typical canopy species include Castanospermum australe,
Elaeocarpus grandis, Grevillea robusta, Cryptocarya obovata, Beilschmiedia obtusifolia, Dysoxylum
mollissimum subsp. molle, Pseudoweinmannia lachnocarpa, Argyrodendron trifoliolatum,
Planchonella australis, Ficus watkinsiana, F. macrophylla forma macrophylla, Aphananthe
philippinensis, Toona ciliata and Syzygium francisii. Emergent Eucalyptus grandis or Lophostemon
confertus may occur. Waterhousea floribunda and Tristaniopsis laurina may occur on banks of stream
channels. Typical sub canopy species include Cryptocarya triplinervis, Archontophoenix
cunninghamiana, Endiandra pubens, Arytera divaricata, Syzygium moorei and Macadamia spp.
Occurs on Quaternary alluvial plains and channels in areas of high rainfall (generally >1300mm).
Riverine. (BVG1M: 4b).
RE 12.3.11:
Eucalyptus tereticornis +/- Eucalyptus siderophloia, Corymbia intermedia open forest on alluvial plains
usually near coast; classed as of concern under the Vegetation Management Act. Corymbia
tessellaris, Lophostemon suaveolens and Melaleuca quinquenervia frequently occur and often form
a low tree layer. Other species present in scattered patches or low densities include Angophora
leiocarpa, E. exserta, E. grandis, E. latisinensis, E. tindaliae, E. racemosa and Melaleuca sieberi.
Corymbia trachyphloia and/or C. citriodora subsp. variegata may dominate on areas of Pleistocene
alluvia. Occurs on Quaternary alluvial plains and drainage lines along coastal lowlands. Rainfall
usually exceeds 1000mm/y. Contains Palustrine. (BVG1M: 16c).
RE 12.3.2:
Eucalyptus grandis tall open forest on alluvial plains; classed as of concern under the Vegetation
Management Act. Eucalyptus grandis +/- E. microcorys, Lophostemon confertus tall open forest often
with vine forest understorey ('wet sclerophyll'). Patches of Eucalyptus pilularis sometimes present
especially in vicinity of sedimentary rocks. Fringing streams and in narrow gullies in high rainfall areas.
Riverine. (BVG1M: 8a).
