River. The community is therefore unique in the Torres Strait regional context with future consideration to fire management requirements important for its long-term preservation. 5.2.18 Regional Ecosystem 3.2.15 Photograph 47.

Description: Melaleuca viridiflora, Neofabricia myrtifolia woodland on beach ridges. Status: Not of Concern Vegetation Communities: D8c, D13a, D17i Reference Sites: 1 Secondary (BAS20), 1 Quaternary (PWQ5) Two VC’s are classified under this ecosystem, of which VC13a is the most prominent. Characteristics of these vegetation communities are summarised below. Vegetation Community 13a: Melaleuca viridiflora shrubland and low woodland occupies extensive areas on the broad degraded sand dunes of Badu Island. The community in this location forms a low woodland of 8 to 12m height dominated by Melaleuca viridiflora with scattered Asteromyrtus brassii and rare Corymbia novoguinensis. The sparse shrub layer is composed of Banksia dentata, Pandanus sp., and scattered Acacia crassicarpa. Ground covers 3d Environmental – Torres Strait Regional Ecosystem Mapping Project – August 2008 72
are similarly sparse, dominated by Dapsilanthus spathaceus and a range of scattered herbs such as Drosera spatulata, Eriocaulon sp. and Dianella sp. In the better developed deflationary sand sheets on Badu Island, the community forms a sparse shrubland, verging on a sedgeland in areas where deflation has scoured the overlying sand sheet to its erosional base level (on the capillary fringe of the water table). Several examples of this community are also represented on Horn Island in association with a low dune-swale complex, where the structural and floristic affinities are similar to the examples on Badu Island. In some locations on Badu Island the Melaleuca shrub layer becomes very sparse, and the structural formation grades to a Dapsilanthus spathaceus dominant sedgeland generally with scattered emergent shrubs. These areas are mapped as VC17i, although are retained within the broader group of RE3.2.15. Photograph 49. Low woodland of Melaleuca viridiflora (VC13a) occupying degraded sand dunes on Badu Island (BAS20). Vegetation Community 8c: A variant of the RE, represented as VC8c was mapped on the tapering slope of an old dune system on Muralug Island. The canopy of this community was dominated by Lophostemon suaveolens with Corymbia clarksoniana, Asteromyrtus symphyocarpa, Melaleuca saligna and Melaleuca viridiflora scattered evenly throughout. Melaleuca viridiflora, Pandanus sp., and Banksia dentata formed the dominant sub-canopy component. Corymbia latifolia (shown in Photograph 50) was recorded in this community and in adjoining woodlands of E. tetrodonta and C. nesophila on old beach ridges. The species is known previously from a collection housed at the NSW Herbarium (T. Bean pers. comm. Jan 08). Its occurrence on Muralug and on Zuna verifies a considerable extension of the geographical extent being otherwise known only from the Northern Territory and West Kimberley Region (Brooker et al. 1994) and south west Papua (Conn et al. 2006+). Due to the extremely limited size of this community, it has been classified under RE3.2.15, in the absence of a more suitable classification. 3d Environmental – Torres Strait Regional Ecosystem Mapping Project – August 2008 73
