Project 5.13: Coastal wetland systems repair across GBR catchments: values based causal framework validation.
The Burdekin floodplain includes Australia’s largest sugarcane production district. Concomitant with sugarcane development, the floodplain and waterways are in poor ecological condition, with altered hydrology, poor water quality, and extensive invasive weeds and noxoius fish. Considerable effort continues to be made on reversing the decline in water
quality reaching the Great Barrier Reef (GBR), particularly the Bowling Green Bay Ramsar wetland located along the coastal strip. The floodplain now comprises a highly modified
distribution network used to move Burdekin dam water, which is turbid, across the floodplain to provide shallow groundwater aquifer recharge and surface water resources for two distinct sugarcane irrigation schemes. The floodplain has been the subject of research and restoration for many years, however, it remains in poor condition. This case study took the opportunity to partner with major restoration activities under the direction of local restoration practitioners charged with managing overall threats on the floodplain, in an effort to restore the services and values possible. This case study supports and builds on limnological knowledge on the floodplain (see Davis et al., 2014 review).
