Operation Crayweed is restoring lost underwater forests in the Sydney region for the crayfish and abalone that reside there. These giant reef structures support hundreds of smaller invertebrates that are food for local fish populations. By restoring these forests, we are restoring equilibrium to the food chain.

The goal of Operation Crayweed is to re-establish lost underwater forests of crayweed along the entire Sydney Metropolitan coastline. Crayweed (Phyllospora comosa) is a large seaweed that forms dense forests which dominate shallow rocky reefs along ~2000 km of the Great Southern Reef, from Port Macquarie (NSW) to Tasmania. Crayweed disappeared from 70 km along Sydney’s coastline in the 1980s, most likely due to sewage pollution at the time.

The team behind Operation Crayweed has developed an effective method to re-establish these lost underwater forests by harnessing the power of crayweed reproduction.

Operation Crayweed is a partnership between Sydney Institute of Marine Science, University of New South Wales and University of Sydney.
