  • This record provides an overview of the NESP Marine and Coastal Hub small-scale study - "Quantifying the ecosystem services of the Great Southern Reef". For specific data outputs from this project, please see child records associated with this metadata. -------------------- The Great Southern Reef (GSR) is an interconnected system of reefs dominated by kelp forests spanning over 8,000 km along southern Australia. It is a global hotspot for marine biodiversity and endemism, and one of the most productive ecosystems on Earth. Kelp forests, however, are diminishing and evidence-based management is hindered without accurate estimates of their contribution to society and the economy. In this project, we will systematically compile and synthesise existing data on the ecosystem values and services provided by the GSR, including market and non-market values. These assessments will be aligned with existing accounting standards to ensure compatibility with ongoing and future efforts. Outputs • Inventory of data collated and assessed for the purpose of developing ecosystem accounts for GSR • Final technical report with analysed data, including a short summary of recommendations for policy makers of key findings (written)

  • This record provides an overview of the NESP Marine and Coastal Hub small-scale study - "A national inventory of implemented nature-based solutions to mitigate coastal hazards". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Climate change and continued population growth are accelerating the need for diverse solutions to coastal protection. Traditionally shorelines are armoured with conventional “hard” or “grey” engineering structures, which are non-adaptive and come with significant economic, environmental and social costs. While hard structures will continue to have a place in coastal protection, alternative methods that are more sustainable and climate-resilient should be more broadly adopted into the future where appropriate. Nature-based methods (through “soft” or “hybrid” techniques) have the potential to play important roles in climate adaptation and mitigation because of their ability to reduce the threats of coastal erosion and flooding and provide co-benefits such as carbon sequestration. One reason that nature-based methods have been underutilised in Australia is that decision-makers need clearer guidelines for when a soft, hybrid or hard coastal defence approach is most appropriate. This resulted in the recently published foundational guide (led by Morris and Swearer and delivered under ESCC Hub Project 5.9: Natural habitats for coastal protection and carbon sequestration) to inform the national use of nature-based methods for coastal hazard risk reduction. In the process of producing these guidelines, the lack of a national inventory of coastal protection projects already using nature-based methods was identified by end-users as a priority to enable their wider adoption as an adaptation strategy in Australia. This project generates an online inventory of all current and planned on-ground actions by coastal land managers that have implemented a nature-based solution (NBS) to mitigate coastal hazards. The resulting inventory is the first step in identifying best practice, which will inform the future development of detailed technical design guidelines for implementing different nature-based methods in Australia. Planned Outputs • A national inventory of existing implemented nature-based solutions to mitigate coastal hazards [spatial dataset] • Final technical report with analysed data, including a short summary of recommendations for policy makers of key findings [written]

  • This record provides an overview of the NESP Marine and Coastal Hub Research Plan 2024 project "Assessing the condition of natural values within priority temperate Australian Marine Parks to evaluate management effectiveness". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Parks Australia has developed an adaptive management approach to the Australian Marine Parks (AMPs), which cover 48% of Australia's Exclusive Economic Zone. Key to the success of this framework is robust biological and ecological data to assess the performance of management approaches. The project will collect data to measure the trend in natural values to allow for evaluation of management performance at various levels on the continental shelf regions of four AMPs: Hunter (Temperate East Network), Beagle (South-east Network), South-west Corner and Geographe (South-west Network). These AMPs were selected based on previous partnerships between Parks Australia and NESP projects. This project aligns with Parks Australia’s science plans, supporting adaptive management and addressing emerging threats. Marine sampling and monitoring Standard Operating Procedures (SOPs) will be used to systematically collect data that will provide trusted scientific evidence for decision-makers, aiding in effectively safeguarding the ecological integrity of these marine ecosystems. Outputs • Fish scoring data from BRUV, BOSS and ROV platforms [dataset] • Benthic imagery with annotations from AUV platform [dataset] • Lobster catch data [dataset] • Spatially-referenced highlight videos/imagery for communication purposes [dataset] • Final project report [written]

  • 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]

  • This record provides an overview of the NESP Marine and Coastal Hub Research Plan 2024 project "Delivery of science to support the implementation of a marine park management effectiveness system". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Parks Australia has developed an adaptive management approach to the Australian Marine Parks (AMPs). This Management Effectiveness (ME) system is designed to allow Parks Australia to test the effectiveness of the AMP system and ensure that AMPs are effectively and appropriately managed. Parks Australia have identified priorities for research to assist in the implementation of the ME system, to identify scientific outputs needed for network management and adapt to new issues in the marine environment through the Australian Marine Parks Science Plan. This project will deliver several of the key science needs identified in the plan and will draw on the combined expertise of the partners and scientists within the Marine and Coastal Hub to generate the outcomes which build onto extensive work previously delivered. The project will deliver the following four outputs required for the 2028 National AMP management plan review: 1) Develop monitoring protocols for Tier 1 & 2 priority monitoring sites to assess the effectiveness of management arrangements; 2) Improve workflows for assessing natural values, activities and pressures; 3) Identify and define impacts and management options for emerging industries; and 4) Improve overall understand the entire AMP system through increased collaboration. Outputs • Updated national-scale spatial datasets of: (1) Natural Values Ecosystems; (2) Key Natural Values; (3) Pressures & Activities; (4) Cumulative impacts; (5) Ecosystem-level risk assessment (absolute risk) [datasets] • Refined list of monitoring priorities for AMPs [written] • Monitoring protocols for monitoring priorities [written] • Final project report [written]

  • This record provides an overview of the NESP Marine and Coastal Hub small-scale study - "OzSET: Integration and publication of the Australian Surface Elevation Table dataset". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Australian coastal floodplains and wetlands are threatened by accelerating rates of sea-level rise. The assessment of vulnerability of these environments requires measurements of rates of vertical accretion, subsidence and elevation gain across a range of coastal settings. Australia’s network of Surface Elevation Tables is one of the most extensive in the world, consisting of over 200 benchmark monitoring stations from Westernport Bay, Victoria to Darwin Harbour, NT. We collate and make available through a national platform data on accretion, subsidence and elevation change in mangroves, saltmarshes, seagrasses and tidal freshwater forests, information vital to coastal risk assessment. Planned • SET-MH database: collation of data from existing Surface Elevation Table (SET-MH) stations [dataset] • Final technical report with analysed data, including a short summary of recommendations for policy makers of key findings [written]

  • This record provides an overview of the NESP Marine and Coastal Hub Research Plan 2024 project "Environmental DNA for measuring offshore marine biodiversity: what can DNA in water collected from the RV Investigator tell us?". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Environmental DNA (eDNA) is genetic material that is found in the environment. In marine ecosystems eDNA is ubiquitous in seawater and is derived from everything from bacteria to invertebrates and fishes. eDNA can be recovered by filtering water samples and then used it to characterise biodiversity. Using environmental DNA (eDNA) found in seawater to get a snapshot of the species present in an area is an emerging technology with diverse applications in marine ecosystem monitoring. This project will collect a large eDNA dataset during the Southeast Australian Marine Ecosystem Survey (SEA-MES). The eDNA samples will be taken from the RV Investigator throughout the water column at offshore sites stretching from Tasmania to NSW, including sites within the South-east Marine Park Network. The voyage includes parallel collection of biodiversity data using a suite of conventional methods (nets, cameras, and acoustics) which will allow for an assessment of how eDNA compliments these approaches. The project will provide a new baseline and unique eDNA-based perspective on the biodiversity of the southeast Australian marine region. It will also allow for evaluation of eDNA sampling methods and guidance for design of effective, scalable, and non-extractive biomonitoring tools for marine ecosystems. Outputs • eDNA sequences with associated collection metadata (x2 voyages x50 sites) [dataset] • Final project report [written]

  • This project undertook a rapid exploration of information on a priority subset of species identified by the Department of Climate Change, Energy, the Environment and Water (DCCEEW) and the National Offshore Petroleum Safety and Environment Authority (NOPSEMA) that are listed as critically endangered or endangered under the Environment Protection and Biodiversity Conservation Act 1999. It specifically focused on these species in relation to the Gippsland declaration area, and the adjacent areas to the declaration area in Bass Strait. This rapid exploration of information was conducted as follows: 1) identify datasets and information sources relevant to priority species identified by DCCEEW and NOPSEMA for the Gippsland declaration area; 2) identify the source of these datasets and information and their level of accessibility; 3) evaluate the utility of datasets and information identified in 2) for assessments/regulatory processes required to be undertaken by DCCEEW and NOPSEMA; and 4) identify what activities would need to be undertaken to improve the accessibility and utility of datasets and information sources identified in 3) that are not currently accessible in useable formats. Fifteen priorities species (12 birds, 3 cetaceans) were identified for which publicly-available occurrence data could be located. This record and the attached download describes the data inventory for Humpback Whales (Megaptera novaeangliae). To download the data inventory for all fifteen priority species, see https://doi.org/10.25959/GB51-RW44.
