Restoration of coastal marine habitats is being implemented across the world at varying spatial scales. For many of those restoration efforts, improved benefits to the broader ecosystem is presumed rather than guaranteed. Under the current United Nations Decade of Ecosystem Restoration, performance assessment of restoration efforts should be implemented to ensure that ecosystem functions are evaluated and guaranteed, rather than just assumed. One proposed benefit of shellfish reef restoration is the improvement of sediment stability so that other associated habitats (e.g. seagrass) can flourish as an integrated seascape. To establish a reliable understanding of sediment movement dynamics around a new shellfish restoration site in South Australia, at Glenelg, we employed multiple approaches that could be used to determine if sediments are being stabilised as the reef evolves. Electronic equipment such as an Acoustic Doppler Current Profiler (ADCP), pressure sensors, an acoustic sediment analyser, along with physical sampling for sediment profiles, nutrients and trace elements were used to provide an integrated understanding of hydrodynamics and sediment dynamics. Our modelled data can be built upon through time as we move from habitat to seascape restoration so that sediment stabilisation as an ecosystem value can be defined, improved, and guaranteed into the future.
