3.5.2.1 Description


The water-dependent asset register for the Maranoa-Balonne-Condamine subregion (Bioregional Assessment Programme, 2017) contains 2215 ecological assets (Table 21). This includes:

  • 23 assets in the ‘Groundwater feature (subsurface)’ subgroup, including alluvial aquifers, geological formations, recharge areas and groundwater management areas
  • 1688 assets in the ‘Surface water feature’ subgroup, including several spring complexes, wetlands and lagoons. The spring complexes are part of the 177 springs assessed in Section 3.4
  • 504 assets in the ‘Vegetation’ subgroup, comprising:
    • 313 assets in the ‘Groundwater-dependent ecosystem’ class that rely on either the surface or subsurface expression of groundwater described in the National atlas of groundwater dependent ecosystems (GDE Atlas) (Bureau of Meteorology, 2012) and the Queensland Government GDE mapping (DSITIA, 2012)
    • 171 assets in the ‘Habitat (potential species distribution)’ class that are listed threatened ecological communities, species or regional ecosystems under the Commonwealth’s Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) or Queensland’s Nature Conservation Act 1992 (Nature Conservation Act)
    • 20 assets in the ‘Riparian vegetation’ class that include protected reserves, parks, bird habitats and key environmental assets.
