5.2.10 Regional Ecosystem 3.2.4 Description: Melaleuca leucadendra ± M. dealbata open forest. In dune swales and swamps.. Status: Of Concern Vegetation Communities: 7b, 7d, 7f, 3e, 16c (co) Reference Sites: 4 Secondary Sites (PWQ4, MO66, MO20, BAS39), 17 Quaternary Sites Melaleuca leucadendra dominant communities are a relatively frequent community on dune swale systems of the Inner and Near Western Island groups. The extent of this RE is somewhat broadened by a range of Melaleuca dominant communities. These communities provide valuable wetland (palustrine) habitat and may be inundated for a number of months over the wet season. Vegetation Community 7b: Melaleuca saligna forms the dominant canopy in VC7b, which is a relatively widespread community in dune swale systems on Moa Island where it is mapped as RE sub-type 3.2.4d. Remnants of it are also recognised on Mabuiag Island where it has been extensively cleared for residential development. It is ecologically and structurally similar to VC7f although canopy heights are often significantly lower, in the range of 15 to 20m. There is currently no RE or RE subtype classification that comfortably accommodates this vegetation community and it is suggested that an additional RE sub-type be erected to provide a suitable classification. Dependant on studies of the broader CYP bio-region, a sufficient extent of this community may be recognised to warrant an individual RE classification. A complex of VC7b and 14t (RE3.2.5) recognised near Kubin on Moa Island as complex type 16c (sites MOQ118 to MOQ120) appears to be similarly unique. Vegetation Community 7d: Melaleuca quinquenervia forms the dominant canopy component of VC7d (sampled at Site MOQ66), which is restricted to a broad swale south of Saveka Point on Moa Island. The community is mapped as RE sub-type 3.2.4b in this exercise, based on recommendations from the Queensland Herbarium. Sub-dominant canopy species in this community include Lophostemon suaveolens, Melaleuca saligna and Melaleuca cajuputi and canopy heights attain 20m. The sub canopy is dominated by Livistona muelleri and includes Lophostemon suaveolens, Melaleuca quinquenervia, Acacia crassicarpa and a host of epiphytes such as Myrmecodia platytyrea subsp. antoinii, Dendrobium triamellatum, Dischidia major and Hydnophytum moseleyanum var. moseleyanum. A sparse understorey comprises Acacia leptocarpa, Melaleuca quinquenervia, Acacia crassicarpa, Livistona muelleri and Glochidion disparipes. Similar communities are classified as RE sub-type 3.2.4b in current mapping databases (REDD, Version 5.2, 2007) and this occurrence has been similarly classified. The extent of such communities in the Torres Strait Islands appears however to be extremely restricted. Photograph 28.

Vegetation Community 7f: VC7f forms what would probably be considered the type example of RE3.2.4 (classified in this exercise as RE3.2.4a) comprising a tall open forest of Melaleuca leucadendra (canopy 30-35m). In its best development sampled behind Long Beach on Muralug (Site PWQ4) the sub-canopy is extremely sparse comprising Livistona muelleri, Melaleuca saligna, Melaleuca cajuputi and Ficus virens. Well-developed examples also occur on Friday Island (Site FQ3) where the understorey of the features Livistona muelleri, Glochidion apodogynum, Cyclophyllum maritimum, Alstonia spectabilis, Mimusops elengi, Breynia cernua, Acacia polystachya, Pandanus tectorius, Gymnosporia inermis, and Vitex acuminata. 3d Environmental – Torres Strait Regional Ecosystem Mapping Project – August 2008 61
