Description: Deciduous vine thicket. Occurs on granite slopes mainly on the Great Dividing<br />
Range <strong>and</strong> offshore isl<strong>and</strong>s.<br />
Status: Of Concern<br />

Reference Sites: 3 Secondary (DA01, DA32, DA47), 18 Quaternary<br />
<strong>Regional</strong> Ecosystem 3.12.21 represents a diverse array of floristic <strong>and</strong> structural variations of<br />
semi-deciduous <strong>and</strong> deciduous vine thicket mapped individually in the <strong>Vegetation</strong> Community<br />
Classifications 2b, 2f, 2x, 2n, 2v <strong>and</strong> 2s. This RE also comprises components of the<br />
vegetacomplexes 18c <strong>and</strong> 14d. The features of the major VC’s are discussed briefly below. All<br />
component VC’s are described under the sub-unit RE 3.12.21a. <strong>Vegetation</strong> 2v, being an Acacia<br />
polystachya dominant variation, is poorly sampled <strong>and</strong> as such, is not included in the vegetation<br />
descriptions.<br />
<strong>Vegetation</strong> Community 2b: This is a floristically uniform community on the granite boulder<br />
footslopes of Dauan Isl<strong>and</strong>. The community, which was nearly fully deciduous at the time of<br />
survey, forms a semi-deciduous notophyll vine thicket <strong>and</strong> occasional low closed forest.<br />
Dominant canopy species include Canarium australianum, Cochlospermum gillivraei, Bombax<br />
ceiba var. leiocarpum, Cleistanthus peninsularis, Cupaniopsis anacardioides, Pouteria sericea,<br />
Ficus virens var. sublanceolata, Terminalia subacroptera, Elaeocarpus arnhemicus <strong>and</strong><br />
Manilkara kauki. The understorey is diverse comprising Glycosmis trifoliata, Dimorphocalyx<br />
australiensis, Salacia disepala, Psydrax reticulata, Cyclophyllum maritimum, Cupaniopsis<br />
anacardioides, Memecylon pauciflorum, Cliestanthus peninsularis, Micromelum minutum,<br />
Ganophyllum falcatum, Cryptocarya exfoliata, Litsea glutinosa, Tabernaemontana orientalis,<br />
Eugenia reinwardtiana, Drypetes deplanchei, Diospyros reticulatus, Aidia racemosa, Capparis<br />
sepiaria, Ixora timorensis, Exocarpos latifolius, Cathormion umbellatum subsp. monoliforme,<br />
Celtis philippensis, Murraya ovatifoliolata, Cryptocarya exfoliata, Litsea glutinosa, Diospyros<br />
reticulatus, Chionanthus ramiflora, Pleomele angustifolia, Macaranga tanarius, Pouteria<br />
sericea, <strong>and</strong> Ficus obliqua var. obliqua. Thin wiry vines are numerous such as Gymnosporia<br />
inermis, Trophis sc<strong>and</strong>ens, Cissus sp., Flagellaria indica, Cansjera leptostachya, Hoya australe<br />
subsp. sanae <strong>and</strong> Jasminum elongata.<br />
