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 5 2. Previous Mapping Land System Mapping Land system mapping is a broad scale survey considered to be the reconnaissance stage of the collection and interpretation of land resource information (Lynch and Wilson 1998). It describes the land resources at a regional scale which can be refined later in greater detail such as land unit mapping that identifies smaller and increasingly homogenous land types. Land system mapping is usually undertaken at a scale of 1:250 000 to 1:1 000 000 although some regions have been mapped at 1:100 000. The Land Systems of the VRD including Auvergne Station were described by CSIRO in 1970. The Lands of the Ord-Victoria Area, W.A. and N.T. provided broad descriptions of pasture lands at a scale of 1:100 000 that are still referenced today. Land systems were remapped over the northern part of the VRD at 1:250 000 as part of the Northern Territory contribution to the Australian Soil Resource Information System (ASRIS). Although this mapping provides more detail, the land systems and their descriptions are considered interim and are based on the original descriptions used by CSIRO. These updates can be found in the Land Systems for the Northern Part of the Northern Territory DRAFT (Lynch et al. 2012). Land Unit and Vegetation Mapping Land unit mapping is similar to land system mapping however the survey area is studied in greater detail. These areas usually have relatively similar landform, soil and vegetation features and present as a uniform pattern on aerial photography or satellite imagery. Variation within a land unit does occur, however these are usually too small to map separately at the given survey scale. In the Northern Territory, land units are commonly mapped at either 1:25 000, 1:50 000 or 1:100 000. Land unit mapping for the VRD was completed in 2012 at a scale of 1:100 000. Although Auvergne Station was not covered in the original VRD report, 160 vegetation sites were described in 1998 and these sites have been used and incorporated in this report. The 1998 survey describing the vegetation communities on Auvergne and Spirit Hills Stations can be found in Brocklehurst et al. (1998) Reconnaissance Land Resource Survey of Auvergne Station and Sections of Spirit Hills Station, Northern Territory. Soil studies A study of the soils of the North and East Kimberleys was undertaken in 1986 and one site was collected near the West Baines on Auvergne and sent for chemical and physical analyses. The results can be found in Isbell and Chapman (1986) Studies of Rangeland Soils in the North and East Kimberley Regions, North West Australia.
