This record provides an overview of the NESP Marine and Coastal Hub small-scale study - "Quantifying the ecosystem services of the Great Southern Reef". For specific data outputs from this project, please see child records associated with this metadata. The Great Southern Reef (GSR) is an 8,000 km network of temperate rocky reefs stretching from Western Australia to New South Wales. Dominated by kelp forests, it is one of the world’s most biodiverse and productive marine ecosystems, supporting important fisheries, tourism, cultural values, and ecological functions. Despite its significance, kelp forests are in decline due to ocean warming, marine heatwaves, pollution, and expanding herbivore populations—threatening both biodiversity and the services these reefs provide. Evidence-based management is hindered without accurate estimates of the GSR's contribution to society and the economy. This project delivered the first systematic synthesis of existing data on the ecosystem services and economic value of the GSR, focusing on shallow reefs (0–50 m). Market and non-market services—such as commercial and recreational fishing, tourism, carbon sequestration, and existence value—were assessed for each state in which the GSR occurs. The synthesis highlighted the high societal dependence on the GSR, with over 17 million Australians living within 50 km of its waters and significant national engagement in related economic and cultural activities. All data inventoried by the project were aligned with national and international environmental-economic accounting standards to support future inclusion in Australia’s ocean accounting frameworks. This inventory provides the foundation for developing a national ocean account for kelp forests, and identifies the key data gaps that must be addressed to fully capture the GSR’s value and guide long-term policy and investment. Outputs • Inventory of data collated and assessed for the purpose of developing ecosystem accounts for GSR • Final technical report with analysed data, including a short summary of recommendations for policy makers of key findings (written)
