Appendix 2 - Vegetation Communities and Regional Ecosystems

The understorey is diverse featuring Memecylon pauciflorum, Dimorphocalyx australiensis,
Drypetes deplanchei, Eugenia reinwardtiana, Exocarpos latifolius, Micromelum minutum,
Murraya ovatifoliolata, Glycosmis trifoliata, Turraea pubescens, Manilkara kauki, Litsea
glutinosa, Cryptocarya exfoliata, Wrightia pubescens subsp penicillata, Diospyros hebecarpa,
Chionanthus ramiflora, Cupaniopsis anacardioides, Ixora timorensis, Streblus brunonianus,
Luvunga monophylla, Miliusa traceyi, Diospyros compacta, Alyxia spicata, Aidia racemosa,
Micromelum minutum, Arytera bifoliolata, and Intsia bijuga. Typical vines are Capparis
quiniflora, Derris trifoliata, Trophis scandens, Opilia armentacea, Flagellaria indica, Secamone
elliptica, and Salacia disepala.
Vegetation Community 2s: This vine thicket variant occupies windsheared upper slope
positions on Dauan Island. Limited floristic information was gathered for this community due to
its occurrence on a precipitous slope, which greatly limited the ability to sample safely. Thus the
community description pertains largely to canopy features which were recorded though
observation. The canopy is relatively even with strong wind shearing and typical height
estimated at 8m. Dominant canopy species comprised Ficus virens var. sublanceolata, Pouteria
sericea, Shefflera actinophylla, Pouteria obovata, Garcinia warrenii, Syzygium puberulum, Ficus
microcarpa, Acmenosperma claviflorum, Ficus destruens, Terminalia subacroptera, Myristica
insipida, Canarium australianum, Arytera divaricata, Aglaia elaeagnoidea and Drypetes
deplanchei.
