Managing natural systems without knowledge of their previous state is like navagating without a map. The power of such research on policy development is hard to overstate.
Two hundred years ago our coast was oyster reef
Our discovery of 1500 kilometres of lost reef has made managers think about restoration of these reefs. What did they once provide nature?
We have projects on discovering their food and habitat potential for increased fish productivity and filtration capacity for clear coastal waters.

Seventy years of poleward movement
Our discovery suggests that seaweeds have been moving polewards for a long time.
Ocean warming may be accelerating, but it is not recent and not insignificant for plant and animal life.

Thirty years ago we had 'urban' kelp forests
Our recovery of the urban kelp baseline enabled cross-government concenus on the need to improve water quality. Previously, the absence of urban kelp was argued to be natural and water improvement unnecssary. South Australia now aims to reduce its release of nitrogen by 75% to our urban coast.
