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 12 absent elsewhere in the VRD are widespread and are common on Auvergne. Hummock grasslands with scattered trees or Eucalyptus pruinosa (Silver box) low open woodland communities also occur but are not as widespread. Alluvium Alluvium is widespread in the Auvergne valley encompassing four main land types. The first group is the extensive alluvial plains that run from north to south. These areas are pastorally productive and are dominated by Vertosols (including aquic Vertosols) and Hydrosols particularly in the north where the major river systems and internal drainage influence the nature of these landscapes. In particularly wet years it is common for these plains to be inundated for lengthy periods. The second group is the major river systems and stream channels and their associated floodouts, banks, and levees, both active and relict. The river systems include areas formed from high energy fluvial action such as channels and banks and low energy alluvial backplains. The river systems generally contain red and brown earths (Red and Brown Kandosols). In some cases the stream beds have eroded back to basement rocks. The backplains or flood-outs generally contain finer and heavier textured cracking clay soils (Vertosols). In the case of the Victoria and Baines rivers the relict levee systems can extend some distance from the current stream channel. The vegetation along river systems and creeks is highly variable, but is generally characterised by riparian communities such as the Corymbia bella (Ghost gum) or Eucalyptus camaldulensis (River red gum) woodland communities. The third group is the wetlands and broad drainage depressions that are dispersed throughout the property. Again these areas are either cracking clays (Aquic Vertosols) or Oxyaquic or Redoxic Hydrosols and often dont dry until quite late in the year. Vegetation is commonly Melaleuca viridiflora (Broad-leaved paperbark) low open woodlands or in reasonably large systems, sedgelands of Eleocharis spp. are common. Marine Alluvium The fourth group is the marine plains near the mouth of the West Baines and along the Victoria River. These areas have been formed from both estuarine and alluvial deposition. At the surface they appear to be similar to alluvial plains, but differ by the underlying marine sediments. These Holocene clay plains are underlain by estuarine sediments similar to those described in Lewis et al. (2010) and Tickell and Hill (2001) on Bullo River and Legune Stations. The flat landscapes are often salt encrusted and support samphire and grass communities tolerant of semi-saline conditions. The soils are generally silty Hypersalic and Supratidal Hydrosols. Tidal creeks and drainage lines dissect the landscape and contain poorly drained cracking clays (Vertosols) and non-cracking clays (Hydrosols) while supporting mangrove species or communities. Colluvium The colluvium group is quite variable including remnant and active colluvial landscapes. These landscapes are generally level to gently undulating plains, footslopes and rises with little rock. On Auvergne the colluvium group represents a block at the southern base of the Pinkerton Range and large areas to the east at the base of the rugged terrain of Judbarra National Park.
