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.

. L . . \ tootifioa on shallower soils. Species composition in inid stratum similar to Community 13 but generally denser cover. Grassland ground cover, with a variety of shrubs, herbs and occasional vines. Understorey shrubs, tree seedlings vary in height and density with seasonal variation and recent fire history. A widespread community closely allied to community 13, varying in density and cover of upper and inid layers, and with generally denser, more varied ground cover. Eucalyptus mixed species. low woodland, including Eucalyptus miniata, E. napuana and E. polyoarpa. Pennisetum polystachion is common in ground cover. Contains disturbed or cleared areas, some poorly degraded, Disturbed or degraded Unit 15 woodland to open woodland. Disturbance events include fire and weed impacts following severe cyclone damage, partial or selective clearing over recent history, and networks of trails and tracks. Bare areas are common, with some shrubby regeneration. Eucalyptus miniata, E. tetrodonta, E. -bleeseri woodland to open woodland, with E. teetMea as an occasional subdominant tree. Commonly sparse inid layer with dense grassland ground cover. Occurs on shallow plateau surfaces, and is allied to Communities 13 and 15. Eucalyptus teetifioa low open wood'land, with E. o1avigera and Xanthostemon paradoxus as sub-dominant trees, and scattered E. polyoarpa emergents. Mid stratum may be absent or if present includes such species as BUGhanania obovata and'Greyillea deourrens. Grasses dominate the ground layer, including Sorghum intrans and Eriaehne' ciliata, with a variety of herbs and shrubs. Eucalyptus papuana, E. polyoarpa, Pandanus spiralis, Erythrophleum chlorostaohys, mixed species low woodland to low open woodland, with Syzygium suborbiou!are andXanthostemon paradoxus. The grassland/shrubland understorey includes Eriachne burkittiiand E. triseta. This sometimes forms a 3. , 5a 3.15b 3.16 3. ,7 3.33 . 1.1
