A recent study published in Nature Ecology and Evolution journal provides support for better control over flood flows such as would be captured by the New Bradfield Scheme and redirected to storage dams inland. Flood flows carry debris, sediments, nutrients, and other pollutants into the coastal regions – and add further stress to the Great Barrier Reef. Improving local water quality may help some reefs better withstand the bleaching impacts of climate change.
Using a composite water quality index, we find that while reefs exposed to poor water quality are more resistant to coral bleaching, they recover from disturbance more slowly and are more susceptible to outbreaks of crown-of-thorns starfish and coral disease—with a net negative impact on recovery and long-term hard coral cover.
