This proposal seeks to restore 2.25 hectares of native Angasi oyster reefs at two sites in the Derwent Estuary and D'Entrecasteaux Channel. This will involve constructing patches of low-profile artificial reef at 8-12m depth, using around 1680 tonnes of quarried limestone. The reef patches will be seeded with hatchery-produced native flat oysters, settled on scallop shells. Over time, it is expected that the reefs will become colonised by the native Angasi oysters, thereby enhancing the associated ecological communities.
The two proposed reef sites are:
- Dixons Beach, Taroona (Derwent Estuary)
- Helliwells Point, Woodbridge (D'Entrecasteaux Channel)
The above proposal has been referred to the Board of the Environment Protection Authority (the Board) for assessment under Section 27 of the Environmental Management and Pollution Control Act 1994 (EMPC Act). An Environmental Impact Statement (EIS) has been lodged in support.
