1.3.2 Ecological assets

Summary

The water-dependent asset register for the preliminary assessment extent (PAE) of the Arckaringa subregion contains 1845 individual ecological assets. The water-dependent ecological assets encompass a large proportion of the area of the PAE. The asset register consists of 1027 assets in the ‘Vegetation’ subgroup, 88 in the ‘Groundwater’ subgroup and 730 in the ‘Surface water’ subgroup. All nominated surface water and groundwater assets were assessed as water dependent. Of the nominated ‘Vegetation’ subgroup assets, 383 groundwater-dependent ecosystem (GDE) assets were excluded because of their low reliability status and a lack of evidence of water dependence using the datasets based on satellite imagery. Furthermore, 10 species habitat assets were excluded as the habitats could not be shown to fulfil the criteria for water dependence. The asset register includes one threatened ecological community and the potential spatial habitat distribution of nine species listed under the Commonwealth’s Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act).
