This record provides an overview of the NESP Marine and Coastal Hub scoping study - "Scoping for an Australian Wetland Inventory: identifying knowledge gaps and solutions for mapping Australian marine and coastal wetlands". No data outputs were generated by this project. -------------------- Marine and coastal wetlands provide extensive ecosystem services—protecting shorelines, improving water quality, supporting healthy fisheries, promoting tourism, storing carbon, and holding cultural significance for Aboriginal and Torres Strait Islander people. Like many wetlands around the world, Australian wetlands continue to be threatened, degraded, and lost due to climate change, development, and other human activities. To support the Australian Government’s development of a national wetland inventory, this project assessed the current state of coastal wetland mapping across five key areas: seagrass, saltmarsh, intertidal macroalgae, shorebird habitat, and blue carbon. It identified major knowledge and inventory gaps through a combination of literature review and consultation with 73 end-users and experts, resulting in 25 targeted recommendations to guide future mapping and data integration. A summary of the status of mapping habitat attributes and ecosystem services such as blue carbon, coastal protection and shorebird habitat is available in the project's Final Technical Report. This report incudes recommendations to guide investment in high-demand areas and support nationally consistent wetland management and reporting to address key knowledge gaps.
