Shellfish Reefs project wins Eureka Prize
成人大片 marine ecologists are among a team of scientists awarded a Eureka Prize for their research towards rebuilding Australia鈥檚 lost shellfish reefs.
Our researcher from the Environment Institute,听Dr Dominic McAfee听and the School of Biological Sciences, and听Dr Heidi Alleway, from the Division of Research and Innovation, joined researchers from v in winning the NSW Environment, Energy and Science (DPIE) Eureka Prize for Applied Environmental Research.
Shellfish reefs, once common across the temperate bays and estuaries of southern Australia, have been overexploited to near extinction.
This research has documented the decline and provided the knowledge required to successfully commence restoring them and their vital ecosystem services, such as cleaner water, more fish and protected shorelines.
Much of the groundwork for the research stems from Dr Heidi Alleway's work with听Professor Sean Connell听on the ecological baseline for SA's shellfish reefs, published in the journal听Conservation Biology听in 2015.
This work was pivotal to realising Australia's first large-scale restoration 鈥 the Windara Reef, Yorke Peninsula.
Dr McAfee joined the University鈥檚 marine ecology group in 2017, working with Professor Connell on understanding the ecology and function of shellfish reefs in NSW and SA. He has now been working on oyster reefs for eight years.
鈥淔or thousands of years, oysters were of great cultural importance to Australia鈥檚 Indigenous communities, as food for mass social gatherings and using their shells to fashion fishhooks and cutting tools,鈥 says Dr McAfee.
鈥淥ysters also played a large role in Australia鈥檚 colonial history鈥 its shell was burned to produce lime, and the colony鈥檚 first buildings were built with the help of oyster cement.
鈥淯nfortunately the insatiable appetite of our colonial ancestors brought overexploitation and oyster populations crashed within a century of colonisation. Today oyster populations are at less than 1% of their pre-colonial extent in Australia.鈥
Dr McAfee says oysters are an 鈥榚cological superhero鈥.
鈥淭hey have the capacity to increase marine biodiversity, clean coastal waters, enhance neighbouring seagrass, reduce coastal erosion, and even reduce the impacts of climate change,鈥 he says.
鈥淩estoring oyster reefs has the potential to return these ecosystem services and increase the productivity of our coastal ecosystems.鈥
Dr McAfee and Dr Alleway are part of the Australian Shellfish Restoration Network. Inspired by restoration success abroad, the team of researchers and conservationists is resurrecting shellfish reefs at a national scale, providing global leadership in ecosystem recovery.
