The resultant community complex ranges from Low to Tall Closed forest grading into Mid High to Tall Closed Shrublands, all occurring in dis crete bands or zones related to the abovementioned fac tors. The mangrove communities of Cobourg Peninsula tend to fall in the Mid-High to Tall Closed Forest range with some areas of Low Closed Forest or shrublands on the landward fringe. These mangrove communities are typical of the vast areas of mangroves occurring along the Northern Territory coasts - particularly of those occurr ing along the western and northern coastl ines. Such communities have not been well represented in our natio nal parks to date." For these reasons the ir conservation value is high. Added to this current botan ical research indicates that the north Austral ian man grove communities are more diverse than has been thought in the past and the Cobourg Peninsula mangrove communities provide ideal sites for continuing botanic al research: CAppendix V contain~ a full 1 ist of species coll ected from this community.} - 39. 8 km 2) f"'~~',,,z,,,, Interspersed with the. mangroves desc',ibed above are large expanses of completely unvegeta'ted sal ine ..

The larger mudflats have been mapped ~eparately and are thus given a separate map un it number ~ 5.3.4 Minor communities not appearing as discrete map units Many of the communities described above contain isolated pockets of vegetation types quite different from the ir sur: roundings and too small to be mapped at the current scale. Such communities are often of great, interest to park planners and managers because of their rarity or their unusual nature and beca"use they often contain species which are rare or en dangered. The following descriptions contain b~ief structural and floristic summaries of some such communities. - 41
