2022-05-16 GC Agenda - Item 7 - Attachment 2 - Noosa Oyster Ecosystem Restoration Project - Project Restoration Plan

                 The works proposed in this submission are intended to restore 3,600m2 of oyster beds in phase 1 of
                 the project. That equates to between 1.7 and 9 percent of the original area expected to have been
                 covered by oyster beds in the Noosa River estuary.

                 Restoration Benefits

                 The benefits of restoring rock oyster ecosystems to the Noosa River estuary are extensive. Oysters are
                 ecosystem engineer species capable of improving ecosystem function and providing habitat for other
                 organisms4. Oyster ecosystems added extensive ‘natural infrastructure’ to the estuary and provided the
                 estuary with a range of environmental benefits.

                 These benefits include:
                    • Providing complex habitats for marine species (the diverse habitats typically consist of fish,
                        invertebrates, corals, ascidians, lace corals, encrusting sponges and algae).
                    • Filtering water and removing suspended sediment and pollution.
                    • Processing nutrients; providing bank stabilization and protection.
                    • Providing complex vertical and horizontal living spaces, and feeding grounds, for a multitude of
                        intertidal and marine creatures.
                    • Enhancing marine and coastal lifestyle and tourism activities such as fishing, diving and bird
                        watching.

                 The recognition of the significant contribution of oyster ecosystems led to their recognition as an
                 important wetland habitat type in the Convention on Wetlands of International Importance (The
                 Ramsar Convention – habitat type ‘Ga’)5.

                 1.4 Restoration approach

                 The restoration approach follows the eight principles for ecological restoration established by the
                 international Society of Ecological Restoration (SER)6, which have been newly interpreted for shellfish
                 restoration7. The project approach is also guided by best-practice ecological restoration and shellfish
                 restoration monitoring guidelines, including the Open Standards for the Practice of Conservation8, the
