Maroochy River floodplain
Blue Heart
A floodplain handed back to the water
>5,000 hectares
of floodplain being restored
On low ground cut off from its own river a century ago — drained for cane and grazing — the tide is being let back in. The method is mostly subtraction: cut a gap in an old levee, and the water finds its own way in. Saltmarsh and mangrove return on the tidal flats, freshwater wetland on the ground above. It stores floods that would otherwise reach houses, cleans the water on its way to the bay, and starts the carbon vault filling again.
