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.

. . 4.5 Native vegetation in planning and development Vegetation holds the soil together, increases moisture infiltration and reduces the volume and velocity of run off. Soil erosion occurs as a -natural process, but may be exacerbated by changes in land usage or drainage patterns, or poor land management practices. Undisturbed drainage systems are generally in a state of balance with respect to flow rate and channel size. When catchment systems and drainage lines are vegetated, erosion and siltation are reduced and water flows remain clear. SensitiveIy managed natural systems require less regulation and maintenance compared with modified environments, As far as possible, riparian corridors, drainage lines, seasonalIy inundated areas including freshwater wetlands should retain their natural vegetation cover. Certain vegetation communities act as buffer zones in the system, stabilising, settling soil and filtering water turbulence in dynamic regions of the landscape. Future urban and rural planning should aim to maintain natural environments and address the values of remnant vegetation in. any .proposed developments. Regional planning should incorporate such 'areas into vegetation corridors which provide public access, link open space avenues, and importantly, maintain viable habitat for native fauna. These corridors should be designed to create natural linkages between districts, in contrast to the current situation where bushland is commonly left vulnerable in isolated remnants. A comprehensive bushland strategy is needed to assess natural values in a regional context, taking full account of community interests, integrated open space, and existing native vegetation. . 22 . .
