The National Atlas of Groundwater Dependent Ecosystems presents the current knowledge of groundwater dependent ecosystems across Australia. It displays ecological and hydrogeological information on known groundwater dependent ecosystems and ecosystems that potentially use groundwater. The Atlas is a tool to assist the consideration of ecosystem groundwater requirements in natural resource management, including water planning and environmental impact assessment. The Atlas was funded by the Australian Government through the National Water Commission's Raising National Water Standards Program. It was developed by the National Water Commission, SKM, CSIRO, Cogha and the Bureau of Meteorology with input from every State and Territory as part of the Groundwater Action Plan. A key aim of the Groundwater Action Plan is to improve Australia's understanding of groundwater dependent ecosystems and facilitate how they are considered in water management.
