  • This record provides an overview of the NESP Marine and Coastal Hub small-scale study - "A national framework for improving seagrass restoration". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Across Australia, the loss of >275,000 ha of seagrass meadows and associated ecosystem services – valued at AU$ 5.3 billion – has contributed to the long-term degradation of estuarine and coastal marine ecosystems. Restoration of seagrass is critical for improving the health and function of these ecosystems and sustaining coastal communities and industries that depend on them. This is primarily because restoration practices are piecemeal and driven by local drivers and are generally not conducted at scales of seagrass loss. We address this problem by bringing together scientists and key stakeholders to collate knowledge on seagrass ecology and restoration and generate a framework to scaling-up restoration nationally. We also build on ongoing restoration trials to test the proposed framework.These are: assessing sediment quality and manipulations (Gamay Rangers, UNSW); use of sediment filled hessian tubes for seed and seedling capture (Malgana Rangers, UWA), and: scaling up seed collection for seed-based restoration (Seeds for Snapper, OZFISH, UWA). Planned Outputs • Effect of sediment quality and manipulation on seagrass transplant success (field data) • Locations and health of beachcast fragments of Posidonia in Botany Bay (field data) • Effect of engineering hydrodynamics (by use of hessian socks) on seagrass transplant success (field data)

  • This record provides an overview of the NESP Marine and Coastal Hub Research Plan 2024 project "De-risking nature repair activities in Australian coastal and marine ecosystems". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Scaling up marine and coastal restoration and nature-based solutions (NbS) (“nature repair”) in Australia is necessary to achieve national and international commitments to biodiversity and climate change mitigation and adaptation. The goal of this project is to guide coastal marine nature repair in Australia at scales relevant to help meet national targets through the following aims: 1) Update a stocktake of the coastal and marine restoration and NbS activities which have occurred in Australia. 2) Develop the evidence-base to de-risk coastal and marine nature repair. 3) Scope a forward-looking coordinated framework to support continued implementation of investments in nature repair of Australia’s coastal and marine ecosystems. Addressing these aims is required to move forward beyond uncoordinated efforts to achieve effective seascape-scale interventions that support the Nature Positive Plan and international targets. Outputs • Updates to Australian Coastal Restoration Network database, and the Living Shorelines Australia database [dataset] • Draft national framework for coordinated nature repair [written] • Final project report [written]
