5.3.3 Communities of the coastal fringe ~Ja) Grasslands. (Map Unit 11 - 26.7 km 2) The beach ridge systems of Cobourg Peninsula sup port a Very Tall Grassland with emergent cl umps of Pandanus sp. and Casuarina equisetifolia usually with a distinctive line "of casuarinas immediately behind the active beachfront. The dominant grass ois Sorghum in trans which stands about two meters tall. Beneath this is a sparse to mid-dense stratum of grasses, herbs and sedges~ notably Enneapqgon pa77idus, Fimbristylis nutans, BorrerJa exserta, Pti70tus conicus and Cana val ia maritima. This community is limited to Dune land system, it is representative of similar communities scattered along the Northern Territory coastl ine and therefore has a high conservation value since such"communities are not represented in other National Parks. id-High Woodland (Map Unit 10 - 11.4 km2) In some areas the grassl ands described above are replaced by woodland commmu~ities consisting mainly of Metrosideros eucal YP,toides; ~\ Mel al euca viridif7 ora, Erythri,}a vesperti7io, Timonruj timon/ and Acacia aula cocarpa. This community occurs at Record Point in Port Es_s1ngton and on the northern coastl ine in Mountnorris Bay. As with the grasslands described "above, this community is restricted to Dune land system. 4*(~r Mangroves. (Map Un it 12 - 209.4 km 2) The mangrove community is easily recognised as being distinct from an>, other:. vegetation type; it con tains salt tolerant species, occupies the zone from extreme high tide mark to just below the extreme low water mark and forms a dense-c~nopied c~osed commun ity. Within these cons~raints, however, there is a great deal of variation. Mangrove spec ies tend to occur inmonospecific stands, the relative positions of which depend on such factors as soil salinity levels, - 40
