1.3.2.1 Description


1.3.2.1.1 Introduction to assets by subgroup, class and data source

The total number of ecological water-dependent assets in the PAE of the Galilee subregion is 3973 (from a total of 4122 ecological assets on the asset list). Of the water-dependent assets, 2383 assets are vegetation features, with the remainder surface water features (1439) and groundwater features (151) (Table 7). Most of the vegetation features are groundwater-dependent ecosystems (GDEs). Most of the surface water features are waterholes, pools, rock pools or billabongs. Of the ecological assets, 3610 assets are assessed as dependent on surface water and 3178 assets are assessed as dependent on groundwater. Of these assets, 795 assets are assessed as dependent or possibly dependent on surface water alone, 363 assets are assessed as dependent or possibly dependent on groundwater alone, and 2815 assets are assessed as dependent or possibly dependent on both surface water and groundwater.

Table 8 summarises the assets and their water dependence according to database source. Maps of the distributions of the key data sources are shown in Figure 13 to Figure 22. Total assets cover a large proportion of the 611,000 km2 area of the PAE, giving confidence that the asset register is a thorough basis for the assessment of potential impacts of coal resource developments during later stages of the BA. In some datasets, at least some large assets intersect with only a small part of the PAE and extend far beyond the boundaries of the PAE. This is most strongly the case for the World Heritage Areas dataset, in which the Great Barrier Reef World Heritage Area lies largely to the northeast of the PAE, and for the WAIT dataset, in which Great Artesian Basin groundwater aquifers and recharge beds extend far to the north, west and south of the PAE.

1.3.2.1.2 Threatened ecological communities

Seven ecological communities listed under the EPBC Act occur in the Galilee subregion, and six are assessed as water dependent (Table 9). Management plans indicate only ‘The community of native species dependent on natural discharge of groundwater from the Great Artesian Basin threatened ecological community’ depends on groundwater and the ‘Coolibah – Black Box Woodlands of the Darling Riverine Plains’ and the ‘Brigalow Belt South Bioregions threatened ecological community’ depend on surface water. However, the assessment data based on satellite imagery shows that at least parts of the other four ecological communities are likely to be water dependent, and so these assets are also assessed as water dependent on the basis of the precautionary principle.

1.3.2.1.3 Habitats of threatened species

Of the 39 species listed as threatened under the EPBC Act, 19 species are assessed to rely upon water-dependent habitats, with four species dependent on surface water, six species dependent on groundwater, and nine species dependent on both surface water and groundwater (Table 10). All six EPBC Act-listed species that are only dependent on groundwater are exclusively associated with the community of native species dependent on natural discharge of groundwater from the Great Artesian Basin threatened ecological community (as listed under the EPBC Act). Evidence for dependence on surface water is often much less clear cut. The species occur across a wide range of community types that are more commonly ephemeral rivers, creeks, swamps and floodplains than permanent waterbodies. In such community types, determination of absolute dependence on water in excess of rainfall (i.e. flows down drainage lines and across floodplains) cannot be made with complete confidence, and in all cases the precautionary principle has been applied to assess these species’ habitats.

Of the 78 species listed as threatened under the Nature Conservation Act, excluding those also listed under the EPBC Act, 24 species are assessed to rely upon water-dependent habitats, with 17 species likely or possibly dependent on surface water, one species possibly dependent on groundwater, and six species possibly dependent on both surface water and groundwater (Table 11). Evidence for dependence on surface water or groundwater is not clear cut for most of these species. As for some of the species listed under the EPBC Act, species listed under the Nature Conservation Act occur across a wide range of community types that are more commonly ephemeral than permanent waterbodies. In such community types, determination of absolute dependence on water in excess of rainfall cannot be made with complete confidence, and again the precautionary principle has been applied to assess these species’ habitats.

Although examples of individual species are listed, bioregional assessments consider the potential impact to the habitat of species not individual species per se.
