5.2.19 Regional Ecosystem 3.2.19 Photograph 50. Corymbia latifolia (DGF9199+DJS) forms a scattered canopy tree in VC8b on Muralug (Site PWQ5). Description: Leucopogon yorkensis ± Asteromyrtus brassii open heath on old beach ridges. Status: Of Concern Vegetation Communities: 14n, 14e, Reference Sites: 2 Quaternary (PO4, HI14, MO148) Vegetation communities 14n and 14e provide representation for RE3.2.19. These communities have a scattered distribution, with small areas mapped on Horn, Possession, Muralug and Moa Islands where they occupy deeply leached sand deposits of relict beach ridges. Vegetation Community 14n: This community is classified as RE3.2.19a based on advice provided by the Queensland Herbarium. On Horn Island, the community represents a shrubland dominated by Acacia crassicarpa, Neofabricia myrtifolia, Leucopogon ruscifolius, L. yorkensis, and Cochlospermum gillivraei. These species form a relatively uneven shrubland canopy from 4 to 8m tall and with a scattered low shrub layer of Pouteria sericea, Psydrax banksii, Exocarpos latifolius, Myrsine sp., Alyxia spicata, Breynia oblongifolia, Pandanus sp., Jacksonia thesioides, Drypetes deplanchei and Notelaea ovata. The groundcover is sparse of Lomandra banksii, Aristida sp., and Dianella bambusifolia. Sterculia quadrifida and Premna serratifolia are associated with a number of additional shrubs including Grevillea parallela and Pouteria sericea which join the mix of species on Possession Island. Representative examples of this community 3d Environmental – Torres Strait Regional Ecosystem Mapping Project – August 2008 74
are also mapped on Badu Island where the community occupies a broad dune formation. On Badu, Leucopogon ruscifolius and Acacia crassicarpa form the dominant sparse shrubby canopy, although scattered emergents of Corymbia novoguinensis and Syzygium suborbiculare are occasionally present. The representation on Badu Island occupies an unstable transgressive dune sequence (as discussed in Section 1.1.3 and shown in Photograph 1) and appears to be a transitional to better developed open forest and woodland types on more stable dune formations. A representative community on Possession Island is shown in Photograph 51. Vegetation Community 14e: A single representative unit of VC14e has been mapped on Moa Island where it is represented as RE sub-type 3.2.19b. This community is structurally dissimilar to the RE type description, and has been assigned to RE3.2.19 in the absence of a more suitable classification. The community is a dwarf open shrubland dominated by Leucopogon ruscifolius with co-dominant Melaleuca viridiflora and subdominant Asteromyrtus brassii and Baeckea frutescens. Associated species are Banksia dentata, Acacia crassicarpa, Alyxia spicata and Exocarpos latifolius. The epiphytes Dischidia major and Myrmecodia platytyrea subsp. antoinii are abundant throughout. Ground cover, dominated by Dapsilanthus spathaceus, Schoenus sparteus, Lomandra banksii and Dianella bambusifolia is sparse, with areas of bare sand between the scattered shrubs. The community occupies a deeply leached sand sheet, which forms a low rise above the Tertiary sand plain on which it sits, interpreted to be a relict sand dune based on its position in the landscape and broad crescent shape. The VC is illustrated in Photograph 52. Photograph 51. A relatively extensive occurrence of VC14n (RE3.2.19) on Possession Island. Photograph 52. Sparse low shrubland 14e (RE3.2.19) on relict dune.
