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 71 Land unit 8l13A These are relict channels of the Victoria River system adjacent to its current course and includes backplains and swales (Figure 10.10). Both the soil and vegetation vary in these landscapes. The soils have a very high K factor of 0.061 and moderate levels of fine sand and silt (combined total of 55%) however some areas are extremely sodic (ESP% ranging from 27 46) and extremely saline (ECe (dS/m ranging from 18 26) from below 0.50 cm. These factors in combination highlight that these areas are highly vulnerable to erosion and land degradation. Although these units are in close proximity to the Victoria River they are generally not heavily utilised by cattle because access is often restricted by inundation and rough terrain. The variability in vegetation means that not all areas are palatable to stock. Currently these landscapes are quite stable however if circumstances were to change and these areas are targeted for more intensive purposes, then land management would need to focus on mitigating the contributing land management factors as well as the disturbance to the significant vegetation habitats with this unit.
