Bald reef gets new growth with seaweed transplant

levels of sewage.

Despite improved water quality around Sydney after the introduction of better infrastructure in the 1990s, which pumped sewage into the deeper ocean, the 70 km gap of depleted 'underwater forest' between Palm Beach and Cronulla - has never been able to recover naturally.

Now, with some well-executed intervention, it looks as though this habitat-forming crayweed could make a successful comeback in Sydney's coastal waters.

"This is an environmental good news story," says research supervisor UNSW Professor Peter Steinberg, Director of the Sydney Institute of Marine Science.

"This kind of restoration study has rarely been done in these seaweed-dominated habitats, but our results suggest that we may be able to assist in the recovery of underwater forests on Sydney's reefs, potentially enhancing biodiversity and recreational fishing opportunities along our coastline."

The researchers say their results could provide valuable insights for restoring similar macroalgae marine ecosystems in Australia and globally, but further research is needed to understand the complex processes that affect recruitment and survival.
