Colonists dredged away Sydney's natural oyster reefs. Now, scientists know how best to restore them

• New research has identified optimal design for artificial habitats to support restoration of oyster reefs, based on a detailed understanding of natural oyster reef geometry. • Published in the global journal Nature, the Sydney-based study shows the complex shapes of natural oyster reefs are not random-their structure and arrangement optimize the establishment and survival of developing oysters and their protection from predators.
