In 2024, the Project Seagrass team introduced the Seagrass Hug to our planting methodology. The method was developed by Anouska Mendzil, Senior Science Officer at Project Seagrass and Swansea University, and aims to determine whether surrounding seeding plots with more established transplants provides protection for emerging seeds in restoration practices. Anouska said: “In this restoration methodology trial we sought to incorporate different Zostera marina life stages by means of seeds and transplants, in a planting design aimed to minimise, and test, hydrodynamic impact on planted seagrass. By implementing multiple restoration strategies, we hope to improve seagrass restoration success and gain valuable knowledge in life-stage bottlenecks to seagrass survival and resilience, site-specific interactions, and insights for scaling-up. The Seagrass Consortium have been wonderful partners in collaborating on this cross-European wide trial, working towards furthering our understanding on seagrass meadow restoration, recovery, resilience and rehabilitation” Members of the Project Seagrass team planting seagrass seeds at Thorness, Isle of Wight using the DIS method.

Graphic provided by Anouska Mendzil Initial trials of the method took place as part of spring planting efforts in the Isle of Wight, in South England, forming part of active restoration work taking place as part of the Solent Seascape Project. The approach involves planting seagrass seeds using the Dispenser Injection Seeding (DIS) method (developed by The Fieldwork Company) and surrounding these seeding plots with more established seagrass transplants using a bare-root plant with anchoring peg. Project Seagrass’ planting trials used seagrass transplants grown from seed at our Seagrass Nursery in West Wales and local donor meadow transplants to provide the “hug” which will also be tested as part of the experiment. https://www.projectseagrass.org/wp-content/uploads/2025/11/Template-Website-Images-Landscape.mp4 The Seagrass Hug planting design has been aligned with seagrass planting being undertaken by our partners at The Seagrass Consortium and has been replicated as part of restoration efforts in the Bay of Arcachon, Etang de Berre, the Bay of Santander, Oosterschelde in the Netherlands, North Wales and the Mediterranean Sea at Mallorca. Monitoring of these experimental plots including seagrass traits and environmental parameters will enable us to assess whether this approach provides protection for the emerging seeds. Scaling the trial in collaboration with international partners helps to build our collective knowledge. Results will be published and shared on SeagrassRestorer to share the findings openly and foster further collaboration within the seagrass community.

Scientists have warned efforts to protect and restore marine habitats along the UK’s coastline could be hindered by a lack of public knowledge about these initiatives. In the face of climate change and rising sea levels, nature-based coastal solutions (NBCS) are emerging as a sustainable and environmentally friendly way to protect our shores. These innovative solutions—which include living shorelines, engineered reefs, and restoration of saltmarshes and dunes—offer a greener alternative to traditional hard defenses like seawalls and barriers. However, new research reveals that while NBCS are preferred by many for their environmental benefits, public understanding of their effectiveness lags behind. In a study published in the Journal of Environmental Management, researchers surveyed over 500 UK residents and found a striking divide between public preference and their perception of effectiveness. Most respondents expressed a preference for nature-based coastal solutions due to their sustainability and aesthetic appeal. Yet hard defenses, which were long-established and visibly effective, remained widely thought-of as the most reliable way to mitigate coastal risks like flooding and erosion. Spatial distribution in preferences and perceived effectives for the two active coastal management strategies considered: hard defenses and nature-based coastal solutions. Credit: Journal of Environmental Management (2024). DOI: 10.1016/j.jenvman.2024.123413 The study highlights a critical knowledge gap. Although NBCS offer significant environmental advantages- including carbon sequestration, enhanced biodiversity, and community resilience—their long-term effectiveness is not well understood by the public. This disconnect could hinder efforts to implement NBCS at scale, despite growing calls from the coastal science community to adopt these solutions as a cornerstone of sustainable coastal management. To bridge this gap, researchers emphasize the need for greater public engagement and education about nature-based initiatives. Collaborative approaches, such as systems mapping, could play an important role in involving local communities in the decision-making process. By fostering dialogue among residents, scientists, and policymakers, systems mapping can help ensure that coastal management strategies are both inclusive and effective. Dr. Scott Mahadeo, from the School of Accounting, Economics and Finance at the University of Portsmouth, explains, “Nature based coastal solutions offer a promising path toward sustainable coastal management, combining environmental benefits with resilience against climate challenges. However, our findings highlight a clear knowledge gap between the scientific community’s advocacy for these solutions and the public’s understanding of their effectiveness. Bridging this gap through meaningful dialogue and inclusive decision-making will be key to fostering widespread support and ensuring robust, long-term coastal policies.” The study highlights that coastal zones hold deep socio-cultural significance, from family heritage and community cohesion to recreation and environmental stewardship. Researchers say that any changes to these landscapes can profoundly impact the lives and identities of coastal residents and users. This is why public support and understanding are crucial for the successful adoption of NBCS and other coastal management strategies. Dr. Mahadeo adds, “As the UK and the world grapple with the challenges of climate change, balancing innovative solutions with community needs is essential. The path forward lies in building trust, sharing knowledge, and working together to safeguard our coasts for generations to come.” The University of Portsmouth is involved in several projects that use nature as a potential solution to climate-related or pollution-related issues. These include the Rapid Reduction of Nutrients in Transitional Waters (RaNTrans) project, which is exploring how nature-based approaches can improve and protect marine ecosystems. Restoration projects are also underway across the south coast of England, including the pioneering Blue Marine Foundation’s Solent Oyster Restoration Project, and the UK’s first seascape restoration project the Solent Seascape Project. Both projects are based at the University of Portsmouth’s Institute of Marine Sciences in Langstone Harbour, and aim to restore multiple habitats such as oyster reefs, seagrass meadows, saltmarsh and birds, to reconnect and revive our ailing coastal waters. This latest study was conducted by a team of interdisciplinary scientists—in coastal geomorphology, environmental economics, and human geography—and focused on public perceptions of coastal management in the UK. Using innovative survey and analysis techniques, the authors hope the research will help develop more sustainable and inclusive coastal policies.

Seagrass Restoration Efforts to restore seagrass marine habitat at our two restoration sites on the Isle of Wight began in March and April this year under the Solent Seascape Project. A total of 132,000 seeds and 2,160 transplants have been planted across the two sites. There are plans to continue this planting in spring 2025 using the same methods. Continued monitoring of the restoration sites and WWF seagrass planting trials are undertaken during fieldwork on a monthly basis. Summer Seagrass Seed Harvest During July, we collected seagrass seeds (Zostera marina) from three meadows around the Isle of Wight. We were joined by 117 volunteers and some of our funders and project partners as part of our seagrass seed harvesting wade and pick event. We collectively harvested 101, 710 seeds in total, which will contribute towards 2025’s restoration efforts. Seagrass Safe Sailor We’ve been working with the boating community on the island to explore Advanced Mooring Systems (AMS), and promote seagrass safe sailing practices. Two AMS have been designed and are in the final stages of being installed at Seaview. These AMS provide a demonstration of how AMS can work safelyin a challenging tidal environment with moving sediment and currents, whilst reducing scarring on the extensive seagrass meadow here. In 2025, we’ll be monitoring seagrass recovery at Seaview, and working with local stakeholders to map the seagrass meadow. You can explore our Seagrass Safe Sailor resources here. Fragment Walks This year we, and many volunteers have also been restoring seagrass through fragments (washed up seagrass). We have: Set up two fragment collection points at St Helen’s and Arc Biodiversity in Sandown Run eight fragment collection walks Planted 329 plants over 17m² Run two school-focused fragment collection walks Worked with over 200 volunteers. To find out more about our Fragment Walk initiative visit our blog article. Looking Back and Moving Forward: A Big Thank You to Our Volunteers! This year has been incredibly busy, and we couldn’t have succeeded without our amazing volunteers. Your dedication has been invaluable. As we plan for an exciting 2025, we’re eager to welcome familiar faces back and meet new ones. Let’s make next year even better together! Thank you for being a vital part of the seagrass community.
