There are twothat are automatically ruled out of this component of the analysis. Firstly, the ‘Dryland remnant vegetation’ landscape group is ‘ruled out’ from potential because it comprises vegetation communities that are deemed to be non-water dependent (for further information, see Section 2.3.3 of companion product 2.3 for the Namoi subregion ( )). Secondly, the ‘Human-modified’ landscape group (comprising six landscape classes) is excluded from this analysis because it primarily comprises agricultural and urban landscapes that are highly modified by human activity, and contains a set of ecohydological attributes distinct from the other landscape groups (for further information, see Section 2.3.3 of companion product 2.3 for the Namoi subregion ( )). Attributes of the water dependency of some aspects of these landscapes are considered elsewhere (see Section ) (i.e. the impact of coal resource development on economic assets such as ).
None of the 15 ‘Non-GAB springs’ found in theare located within the . Therefore, this can be ruled out as it is unlikely to be impacted due to .
The remaining three landscape groups, and their respective landscape classes that intersect the 7014 km2 zone of potential hydrological change, are considered dependent on groundwater and/orregimes. These landscape groups, therefore, are potentially impacted due to additional coal resource development.
