Operation Crayweed is working to restore underwater forests of crayweed (scientific name Phyllospora comosa) on the reefs where it once flourished between Palm Beach and Cronulla.

During the 1980s crayweed disappeared completely from the metropolitan area. The high volumes of poorly treated sewage that were pumped directly off Sydney’s coastline before the 1990s is the probable cause of its decline.

The aim of Operation Crayweed is to re-establish this seaweed habitat and food source which is essential for Sydney’s coastal marine biodiversity.

The project team have put together a visually impressive and interesting website that is well worth visiting – see Operation Crayweed.
