This report for Auvergne Station is a supplement to Land Resources of the Victoria River District (2012) and completes the land resource assessment of the district which covers 24 properties and approximately 78 760 km² of pastoral land. Land unit mapping at 1:100 000 describes the landforms, soils and vegetation in the district.

Land Resources of Auvergne Station A supplement to the Land Resources of the Victoria River District 15 5. Landform Eight landform classes have been described in the VRD and are outlined in Table 5.1 and are presented in Figure 5.1. Table 5.1 Landform classes (NCST 2009) Landform class Extent (km2) Plateaux 304 Sideslopes to Plateaux 304 Low Hills (30 90 m) 459 Rises (5 9 m) 320 Plains (0 9 m) 1 301 Alluvial Plains 1 025 Drainage Systems 483 Wetlands 8 Marine 56 Plateaux Plateaux are level to rolling patterns of plains, rises or low hills above a scarp or escarpment. In the VRD they can be elevated flat landscapes through to undulating rises and low hills surrounded in some part by a steep sideslope or escarpment. In some cases, especially on the basalt plateau, they can be surrounded by abrupt scarps or in some parts by gently undulating sideslopes. The plateaux on Auvergne are associated with the Pinkerton Range on the west or the rugged terrain on the Nagurunguru ALT and Judbarra National Park in the south and are derived largely from sandstone and siltstone. A basalt plateau exists in the south-west corner of the lease. Plateau soils are generally shallow (Rudosols) and often littered with rock outcrop and abundant surface rock. Sideslopes Sideslopes are associated with plateaux and are generally very steep (20-50%). They include escarpments, scarps, cliffs, and to some degree, steep erosional hill slopes surrounding plateaux. Sideslopes on Auvergne are derived from the sandstone and siltstone lithology of the Pinkerton Range (Pinkerton Sandstone). A common feature of the soil landscape is the shallowness of the soils (Rudosols) and abundant surface rock and gravel (rock armour). Low Hills Low Hills are landform patterns with low relief (30-90 m). They typically encompass hillcrests and upper, mid and lower hill slopes but also include scarps, mesas, knolls and strike ridges. Low Hills are found on the sandstone landscape (Jasper Gorge Sandstone) that extends from the rugged country on Judbarra National Park boundary on the east and south-east of the
