Victoria River


This Technical Report describes a land resource survey. It was mapped at a survey scale of 1:100 000 and includes a description of the landforms, soils and vegetation for 237 land units. The surveyed area of 74 502km2 is located 700km south west of Darwin and covers 23 major land holdings in the Victoria River District, (VRD) Northern Territory. The objectives of the project were to map, describe and evaluate the pastoral lands of the VRD and provide this information to land managers, industry, government and other relevant stakeholders.
