3.4.2 Landscape classes that are unlikely to be impacted


Landscape classes in the Galilee assessment extent that occur outside the zone of potential hydrological change, where impacts are very unlikely (Table 19), include:

  • 526,658 km2 of remnant vegetation, including 360,204 km2 in the ‘Dryland’; 76,121 km2 in the ‘Floodplain, terrestrial GDE’; 59,555 km2 in the ‘Floodplain, non-wetland’; 19,348 km2 in the ‘Non-floodplain, terrestrial GDE’; 5,783 km2 in the ‘Floodplain, disconnected wetland’; 4,707 km2 in the ‘Floodplain, wetland GDE’; and 519 km2 in the ‘Non-floodplain, disconnected wetland’ landscape groups
  • 71,563 km2 of non-remnant vegetation, including 51,319 km2 in the ‘Dryland’; 10,363 km2 in the ‘Floodplain, non-wetland’; 7,666 km2 in the ‘Non-floodplain, disconnected saline wetland’; 674 km2 in the ‘Floodplain, terrestrial GDE’; 346 km2 in the ‘Floodplain, disconnected wetland’; 263 km2 in the ‘Non-floodplain, terrestrial GDE’; and 98 km2 in the ‘Non-floodplain, wetland GDE’ landscape groups
  • 101,460 km2 of groundwater-dependent vegetation, including 76,796 km2 in the ‘Floodplain, terrestrial GDE’; 19,611 km2 in the ‘Non-floodplain, terrestrial GDE’; 4,796 km2 in the ‘Floodplain, wetland GDE’; and 258 km2 in the ‘Non-floodplain, wetland GDE’ landscape groups
  • 387,170 km of streams, including 45,737 km of streams that are groundwater dependent (‘Streams, GDE’) and 341,433 km of streams that are not groundwater dependent (‘Streams, non-GDE’). Streams outside of the zone predominantly have an intermittent or ephemeral water regime, including ‘Temporary, lowland stream’ (323,930 km), ‘Temporary, lowland GDE stream’ (38,735 km), ‘Temporary, upland stream’ (17,002 km) or ‘Temporary upland GDE stream’ (6,802 km) rather than a perennial or near-perennial water regime (552 km of streams)
  • 20,373 km2 of wetland vegetation, including 8133 km2 of saline wetlands, 6129 km2 in the ‘Floodplain, disconnected wetland’; 4796 km2 in the ‘Floodplain, wetland GDE’; 1058 km2 in the ‘Non-floodplain, disconnected wetland’ and 258 km2 in the ‘Non-floodplain, wetland GDE’ landscape groups
  • 1359 springs, including 6 springs in the Doongmabulla Springs complex and 1353 Great Artesian Basin (GAB) springs that are not otherwise described in the three clusters of springs within the zone (Section 3.4.3).

Table 19 Landscape groups and landscape classes showing, for each one, extent within the assessment extent, extent in zone of potential hydrological change and whether qualitative and/or receptor impact models have been prepared

The extent of each landscape class is either an area of vegetation (km2), length of stream network (km) or count of springs (number).
