Positive cross-habitat interactions such as sediment stabilisation, wave attenuation and nutrient provisioning, can enhance seascape connectivity, ecological functioning and resilience. Incorporating these interactions may help scale-up efforts to repair and restore seascapes. These interactions have been documented to occur on scales ranging from metres to hundreds of kilometres but to plan restoration that explicitly harnesses them, a greater understanding of the place-based spatial scales and dependencies of these interactions is needed. At Facing Island (Port of Gladstone), Queensland, we surveyed transects of intertidal seagrass, oyster and mangrove habitats at varying distances from each other. We characterised the habitats and sampled the current profile, sediment dynamics and biodiversity to identify the types and magnitude of positive cross-habitat interactions occurring among them. Preliminary results suggest that, as expected, oysters play a role in modifying the currents in surrounding habitat and that the sediment dynamics and associated biodiversity respond to the density of habitat formers. Finally, we demonstrate how these data are incorporated into a conceptual model of the site to plan upcoming seascape restoration trials that seek to maximise ecological outcomes by harnessing these positive interactions. These results demonstrate how incorporating seascape connectivity data can inform multi-habitat seascape restoration approaches.
