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.

, ,. . .. , margins. No fire damage was apparent, likewise disturbance from other factors was minor or absent. Isolation and separation from dry mainland habitats have provided long term protection for the patch from fire and intrusion, at the same time giving good fauna habitat. 6.9 Hidden Valley complex (including Rifle Range area) 6.9. , Very small rocky gully on eastern side of Rifle Range plateau (site 66, area approx. 500 sq. in). Dry monsoon rainforest pocket, with Banyans, Myristica insipida, Black Wattles and Calcphyllum si1. 32 species were recorded. Severe fire damage was evident, with few (15-20) mature trees and struggling regeneration, and weedy grasses in lower part of patch and on margins. Another example of a tenuous rainforest patch dotted amongst the more widespread woodland. 6.9.2 The stands of eucalypt open forest on the sideslopes are of generally high quality and .should be regarded as with comments in 1.8. 6.9.3 An extensive plateau dominates the eastern side of the region, largely covered with eucalypt woodland. Tracks and small scrapes are generalised over the surface, with sporadic household rubbish dumping. Much of the plateau edge affords pleasant outlooks, with particularly beautiful views from the southwestern area overlooking the valley, mangroves and Darwin Harbour to the west. 6.9.4 The drainage creek begins near the Studrt Highway I Amy Johnson intersection, and flows to the south west into Reichhardt Ok. Severe weed infestations, especially dense swathes of Mission Grass and Pennisetum 'pedicillatum, occur beside the upper reaches and side arms of the creek. ' Along the creek line itself, Pandanus spiralis is dominant with associated .Lophostemon Iaotifluus, with scattered Acacia auriouliformis, EUodia elle!yana, Timonius timon and MeIaleuoa vindiflora also present. Lower slopes adjacent to the creek are dominated by mixed Pandanus spiralis communities. 6.9.5 Several smallindtistrial businesses are located along Farrell Oresc. , Winnellie, which back onto a series of cliffs and gullies sloping down to the upper western reaches of the creek.
