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 53 Slope Slope is a critical element that influences runoff and soil erosion and, in particular, erodible soils with low levels of vegetative cover during intense rainfall periods. Slopes above 0.5% will generally require detailed erosion and sediment control planning if developed. Even innocuous disturbances on properties such as fence lines, tracks and cattle pads have the potential to become severely degraded given the right conditions.

Most rock outcrop on Auvergne is associated with the steep or rugged terrain on the Pinkerton Range or the sandstone landscape to the east. These areas are generally not utilised for pastoral purposes and are relatively undisturbed by infrastructure and other development.
