Made available via the Publications (Legal Deposit) Act 2004 (NT).; Remnant vegetation is defined as an area of land which contains native vegetation in a natural state. Much remnant vegetation has been lost or seriously degraded as a result of urban expansion, clearing and development. Poor land management practices have also contributed to long term deterioration of native bushland. Factors causing negative impact include uncontrolled fires, weed intrusion, stormwater runoff, unformed tracks with subsequent erosion, and indiscriminate dumping of household and industrial waste. The main aim of this survey was to identify, describe and map areas of native remnant vegetation and to both determine and graphically represent their significance.

An interesting transition community with species allied to dry coastal monsoon rainforest present in all strata. Lophostemon Iaotif/uus, Pandanus spiralis woodland to open forest, sometimes forming closed forest, with Eucalyptus polyoarpa and E. alba emergents, Mid layer may be absent, or if present includes Pandanus spiralis and MeIaieuoa spp. Grass layer is generally dominated by Sorghum intrans and Eriaohne triseta, with Pennisetum polystaohion if near urban areas. A variety of shrubs and herbs are found, often including Lophostemon Iaotifluus regeneration. Common on drainage lines or broad moist flats. Lophostemon Iactifluus mixed species very low open woodland to 5m tall with scattered emergents 10-15m tall. Other species include Pandanus spiralis, Livistons humilis, TerminalIa ferdinandiana, Xanthostemon paradoxus and occasional Malaleuoa vindflora. Mid layer is commonly absent, and dominant grasses include Heteropogon trifleeus, 'Themeda triandra and Eriachne burkittii. Open depressions. PANDANUS COMMUNITIES 3.21 Pandanus spiralis low woodland to very low open woodland, with Lophostemon Iaotifluus, Orevillea preridifolia, TerminalIa ferdinandiana and Livistona humilis. Scattered emergents Eucalyptus alba and E, polycarpa are found on more waterlogged sites. Mid stratum is commonly absent, and ground layer dominants include the grasses Ohrysopogon fallax, Eriaohne burkittii, EUlalia inaokinlayi, Heteropogon trifleeus and Pseudopogonantherum o0. ntortum, and sedges such as Fimbristylis acuminata, F. furva, Rhynoospora submarginata and Soleria caneina.
