The model predicted only very small hydrological changes and therefore the potential impacts were not further assessed.
More than half of the bioregion is used for dryland agriculture (57.5% of the , which is the area in which potential impacts to and are investigated). Natural vegetation covers 37.8% of the area, including woodlands, open forest and rainforest.
The landscape classification is based on the geology; the physical features of the region, known as geomorphology; , which describes the way water moves underground; land use; and ecology. Existing classification systems and were used where relevant and modified as necessary.
At the start of the assessment, representatives from governments, natural resource management groups and community groups identified more than 2000 ecological, economic and sociocultural of value to the community. The list of these assets that could potentially be affected by changes in water due to coal resource development, known as , included (as of August 2015):
- 1520 ecological assets, including the potential habitat of 186 threatened or endangered species, 4 globally important habitats for birds, 170 wetlands, 7 threatened , and 157 ecosystems that rely on
- 752 economic assets, including water access rights
- 160 sociocultural assets, including 110 recreational sites, 15 heritage sites and 35 Indigenous sites.
