Restoration of Australia’s shellfish reefs has been a key component of The Nature Conservancy’s Great Southern Seascapes program since its inception in 2014. There are now active shellfish reef restoration projects established in Port Phillip Bay, Victoria; Gulf St Vincent, South Australia; Oyster Harbour, Western Australia; Noosa and Pumicestone Passage in Queensland.
Shellfish reefs were once one of the dominant habitats in many estuaries across Southern Australia, however overfishing by the early European settlers decimated these reefs, removing a thriving ecosystem and vital benefits to human society. Restoration of shellfish reefs at scale will increase fish productivity, water filtration, stabilisation of sediments and coastal protection.
Pioneering restoration of shellfish reefs in an Australian context has required many elements to align. This presentation will provide an overview of the driving force behind the success of these projects highlighting barriers and challenges. Common project management considerations will be identified as well as restoration, communications, monitoring approaches and mechanisms to increase community involvement. The experience gained and lessons learnt from implementing these projects continues to unfold, and will be valuable information to natural resource managers and other practitioners embarking on similar undertakings.
