1.1.1.1 Definitions used

The Arckaringa subregion is located entirely in SA (Figure 4), and is defined by the extent of the Arckaringa geological basin (see Section 1.1.1for further detail). The subregion spans an area of about 82,505 km² and extends west beyond the Kati Thanda – Lake Eyre surface drainage catchment into the Gairdner surface drainage catchment. The whole of the Arckaringa geological basin is though included within the Lake Eyre Basin bioregion.
