Blue Carbon Ecosystems (BCE) play an important role as profound carbon reservoirs and have the potential to sequester more carbon in an area than any other ecosystem. This has sparked interest in these ecosystems and their potential for use in climate mitigation strategies and more specifically, carbon abatement. BCEs can be restored in areas which have been tidally modified through anthropogenic interventions. One such location which has experienced anthropogenic tidal regime modification is the Lower Shoalhaven River region - a region that has a broad floodplain with many floodgates separating rivers, creeks, and associated tributaries from the tidal influences of the Shoalhaven River Estuary. Recent studies have investigated the Blue Carbon potential at a national and state level, but there are limited studies on the application on a regional scale. Accordingly, using the Blue Carbon Accounting Model (BlueCAM) and its derivative, the Forward Abatement Estimator (FAE) this study aime
