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.

E , . , ~ covers much of the surrounding slopes. Rubbish dumping occurs in localised sites. A small dump containing mostly farm type refuse mars the environment; the origin of the rubbish would appear to be Bentmah Farm. 6. ,0.2 (Site 89 and surrounds). Much of the higher ground surrounding the TDZ supports mixed eucalypt woodland to open woodland; fire impact is commonly severe, particularly with damage to ground layer' vegetation. Undulating landscape to the west of the TDZ includes several small hills which afford pleasant outlooks and elevated views over the nearby mangroves and harbour. Knuckey's Lagoons (site 94). A wonderful aquatic6. ,, environment providing habitat and refuge for birdlife, snakes and rodents; vegetation includes aquatic plants, -fringing grasses and sedges, and Pandanus clumps. String of permanent swamps seasonalIy connected depending on wet season topup. High recreation and birdwatching value. High probability of surrounding grasses (including Mission Grass) on higher ground being annually burnt., 6.12 CSIRO grounds, MCMillan's Rd. (sites 16 & 17). These areas of high quality eucalypt open forest (community 13) have been fire protected for approximately 15 years (D. Braithwait6 pers. coinm. ). At site 16, the inid layer to 6m tall was the dominant layer in projected foliage cover (60%), under sparser upper layer emergents to 17m tall, presumably a reflection of vigourous regrowth since Cyclone Tracy damage in 1974. Minor occurrence of exotics and low density of canopy regeneration in the ground layer were recorded, markedIy less than other comparative sites. Acacia auriculiformis, a rainforest species, was present as seedlings in the ground layer and co-dominant in the inid layer, a situation unlikely to occur in a fire prone habitat. Leaf litter covers of 50-60% were much higher, often double those of other open forest sites. This area provides a good wildlife habitat, where approximately 30 reptile species including Carpet Snake have been recorded (N. Gambold pers. coinm. ). ., . . 6.13 Holmes Jungle Nature Park and. environs The Park is managed by the Conservation Commission of the N. T. 39 :;
