Seagrass meadows are a threatened coastal habitat globally, providing crucial ecosystem services including carbon sequestration, nutrient cycling and fish nursery habitat. Despite their value, seagrass restoration has never been attempted in Moreton Bay, Queensland, where meadow coverage has declined by approximately 20% due to poor water quality and ongoing anthropogenic pressures. As a direct consequence of poor water quality, seed-based restoration methods are unfeasible in the region. We assessed the effectiveness of mature plant transplanting for restoring seagrass extent and function in Moreton Bay. We transplanted 30 x 30cm sods from an adjacent donor meadow into a 25m2 plot on an intertidal flat. Seasonal sampling events since the initial transplant were used to monitor the success of the restored plot for change in seagrass coverage, carbon and nitrogen abatement, and fish community composition in comparison to the adjacent donor meadow and bare sediment. We found that with time, seagrass coverage and shoot length converged to match that of the donor bed, while fish abundance and diversity remained low in the restored meadow. These results will determine whether this method is viable for restoring seagrass in Moreton Bay and will provide a foundation for future seagrass in south-east Queensland.
