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 2023 project "Improving data on the distribution and ecological value of temperate subtidal seagrass in tayaritja (Furneaux Group of Islands), Tasmania". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Seagrass meadows are a dominant marine ecosystem of tayaritja (Furneaux group of Islands) in the north-eastern waters off Tasmania, with historical coarse mapping indicating extensive beds of Posidonia, Amphibolis, Hetreozostera and Zostera seagrass. The beds of Posidonia and Amphibiolis are potentially some of the largest and deepest extents found in temperate waters of Australia. Lack of data on the distribution and ecological value of these seagrass habitats represents a significant knowledge gap in understanding Australian wetland natural assets that provide a range of ecological, social, cultural and economic values. This project aims to map the extent and ecological composition, population structure and blue carbon value of the seagrass beds around tayaritja in partnership with the Tasmanian Aboriginal Centre. This project will help managers and the Aboriginal communities to understand the significance of these seagrass meadows and understand how they may be monitored. Outputs • Seagrass extent and composition map for Furneaux group [dataset] • Video and imagery of seagrass [dataset] • Final project report [written]
