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 30 There is evidence of die back on the usually semi-saline tolerant species Excoecaria parvifolia (Gutta percha) along small tidal creeks indicating that salt levels have increased. (Figure 7.3). Tickell and Hill (2001) identified extreme soil salinity on low-lying deltas on Legune Station and concluded relatively recent sea level rise and shallow marine incursions were responsible. The four sites that highlight areas of concern (18, 25, 67 and 84), presented in Table 7.6 can be linked to these processes and also the tidal influence from the Victoria River and West Baines. Although soil profiles were field tested for salinity, insufficient laboratory data was collected to accurately map salinity risk. Figure 7.4 provides a general assessment of soil salinity risk using the values in Table 7.6 together with an assessment of aerial and satellite imagery, topographic relief, landscape position and proximity of individual mapped polygons to estuarine areas. The mapped areas in Figure 7.4 do not correlate directly with the salinity classes of each land unit in Table 9.9 (9.7 Saline Soils). Although the map of extremely and highly saline soils is considered reasonable, further field investigation would be required to accurately confirm the extent of the secondary salinity risk zone, if intensive developments were proposed. Figure 7.3 Gutta percha (Excoecaria parvifolia) dieback along a creek line due to elevated salt levels. Figure 7.2 Vegetation is unable to grow on these eroded and salt encrusted areas.
