Earlier this month Project Seagrass’ Senior Conservation Officer Katy Waring attended the yearly gathering for coastal communities from the Coastal Communities Network facilitated by Fauna and Flora International. The event was held on the island of Millport at their field studies centre. The 3-day event was inspiring; groups from around Scotland showcased their projects, held skill-sharing workshops, and collectively unpacked common challenges such as funding, advocacy, and management to explore collaborative solutions. Project Seagrass Trustee Rosslyn Barr was also in attendance with her project Edinburgh Shoreline. Rosslyn shared Edinburgh Shoreline’s story, including their part in Restoration Forth and news of an exciting new project they are developing looking at blue mussels. Many of the seagrass groups were in attendance, providing an opportunity to catch up and explore opportunities for collaboration in 2025. As part of the gathering, Katy delivered a pilot of a new survey developed as part of “Accelerate Seagrass” a new collaborative programme with Climate Impact Partners, Deloitte, and the National Oceanography Centre. The survey aims to connect with local ecological knowledge around Scotland on both current and historical seagrass and to understand localised drivers of decline. This data will help identify areas for tailored conservation and restoration work from a social-ecological perspective ensuring resilience of projects. Katy gathered valuable feedback from members of COAST, CROMACH, Eigg Environmental Action Group, and CLP nature action which will be used to inform further development of the survey. Thanks to these projects for their feedback, we are looking forward to sharing the final piece with you soon. The breadth of positive action delivered by these mostly voluntary ran community groups was inspiring and highlights the power of community. Thanks to the team at Fauna and Flora International for inviting us and the work they do supporting these groups to flourish.

Researchers from the University of Liège (BE) studied the fate of the material produced by Posidonia seagrass meadows. This study, carried out in the Mediterranean Sea at STARESO, shows that the dead leaves of what is commonly known as Neptune grass accumulate in shallow areas, where they break down like a compost, remineralizing the organic matter. This has a previously underestimated effect on carbon fluxes in the Mediterranean coastal environments. Surprisingly, alongside this CO2 emission, oxygen production was also measured. This is linked to the presence of photosynthetic organisms living in this compost in the sea, which fundamentally differentiates it from compost on land. The work is published in the journal Estuarine, Coastal and Shelf Science. From left to right: View of the STARESO harbor entrance with Posidonia meadow islands and an accumulation of dead leaves. Close-up of litter accumulation. Experimental benthic incubation device (‘bell’) installed on accumulations of Posidonia dead leaves (10 m deep). Credit: G.Lepoint & W. Champenois / ULiège Posidonia, a flowering plant emblematic of the Mediterranean Sea, commonly known as Neptune grass, forms vast meadows (underwater prairies) in shallow waters (less than 40m deep). “It is a terrestrial plant that recolonized the marine environment several million years ago, a small quirk of evolution,” explains Alberto Borges, an oceanographer at ULiège. “Like most terrestrial plants in our regions, Posidonia loses its oldest leaves in autumn. These dead leaves accumulate as litter (like at the base of trees) in large patches near the seagrass meadows.” It is these accumulations of dead leaves and their breakdown and transformation that interested the researchers who traveled to STARESO, an underwater and oceanographic research station located in Calvi, Corsica, to conduct a study on the primary production and degradation of organic matter in Posidonia litter. “In the litter, the organic matter breaks down and releases nutrients and CO2, like compost in gardens,” explains Gilles Lepoint. “The litter accumulates in open, sun-light areas.” “Every gardener knows that to grow plants, you need nutrients and light. It is on this basis that we conducted our study which led to a surprising first result: in the litter resulting from the accumulation of material that one would initially imagine as dead and inert, we measured oxygen production, a consequence of the photosynthetic activity of macroalgae drifted from rocks, living Posidonia shoots detached from the nearby meadow, and diatoms (microscopic algae) present in the litter.” To summarize, in this nutrient-rich environment, all living plants associated with the litter thrive and photosynthesize. This oxygen production is significant but does not offset the oxygen consumption by the decomposition of the dead leaves. These accumulations, therefore, remain net consumers of oxygen and, consequently, net emitters of CO2, much like compost and litter in terrestrial environments. The second result from this study somewhat surprised the researchers. “While we thought that Posidonia litter degraded relatively quickly, this study showed us the opposite, based on measurements of litter mass loss—it degrades more slowly,” says Alberto Borges. “We measured respiration through short-term (1-day) incubations based on very precise oxygen measurements.” These measurements provided a more realistic and accurate estimate, with lower values than those traditionally obtained by monitoring mass loss over very long periods (several months). This result could modify the current carbon balance calculations for these ecosystems, which are based on traditional mass loss measurements. As part of this study, the researchers also examined the primary production and degradation of organic matter from the macroalgae growing on rocks adjacent to the Posidonia meadows. “We hypothesized that there might be exchanges between the two systems, which one might initially imagine to be separate and compartmented. Once again, we obtained an unexpected result,” says Willy Champenois. “These macroalgae, despite undergoing photosynthesis, were net consumers of oxygen rather than net producers. This means that the communities of bacteria and invertebrates living within the algae community consume more organic matter than the algae produce. This necessarily implies that this excess organic matter must come from an external source.” By calculating a mass balance, the researchers concluded that this excess organic matter was likely provided by the Posidonia in the form of dissolved organic molecules diffusing from the seagrass meadow and litter to the rocks. In summary, there is a two-way exchange between the macroalgae on the rocks and the Posidonia meadows. The macroalgae drifting from the rocks can accumulate in the Posidonia litter and contribute to primary production there. In turn, the seagrass can supply organic molecules that diffuse to the rocks and are assimilated by the bacterial communities associated with the macroalgae on the rocks. A mutually beneficial relationship, indeed. This study provides new insights into the quantification and understanding of the organic carbon balance of Posidonia seagrass meadows in the Bay of Calvi, which has been the subject of research by oceanographers and marine biologists at the University of Liège since the 1980s, notably through the STARESO marine research station.

Climate Impact Partners and Deloitte, in collaboration with Project Seagrass and the UK’s National Oceanography Centre, announce a groundbreaking program to fund UK seagrass recovery and unlock long-term finance to save and reinstate vital seagrass meadows. The program will fund critical research across UK seagrass meadows, mapping the ecosystems and developing methods to restore them at scale. Crucially, this work will support the development of a new seagrass carbon code in the UK and beyond – enabling companies to finance seagrass recovery at greater speed and scale. Despite seagrass’ crucial role in sequestering carbon, protecting coastlines, and supporting marine biodiversity; seagrass restoration has been underfunded, with nearly a third of seagrass lost globally in the last century. This program will look to address the barriers that prevent finance flowing to seagrass restoration, including improving the scientific knowledge of carbon sequestration, piloting new techniques for seagrass propagation and engaging communities in meadow restoration. This program forms a key part of Deloitte’s Beyond Value Chain Mitigation (BVCM) activities, supporting innovative solutions outside their value chain. Deloitte is using skills, influence and targeted investment to catalyze environmental and social impact across the energy transition, circularity, sustainable food systems and nature restoration. “Reaching net-zero will require the global economy to decarbonize as part of a connected system,” said Smruti Naik-Jones, Chief Sustainability Officer of Deloitte UK and North & South Europe. “This incredible seagrass program, developed by Climate Impact Partners, enables us to learn more about these marine ecosystems, fund critical research and help unlock a powerful tool in the fight against the climate crisis.” “Deloitte is demonstrating true climate leadership through this program. Seagrass offers a unique opportunity to mitigate climate change while delivering significant co-benefits for biodiversity and coastal communities,” said Kirsty Schneeberger, Head of Product Innovation at Climate Impact Partners. “Imagine seagrass meadows as underwater vaults – they lock away enormous amounts of carbon for long periods, potentially millennia, as long as they remain healthy and undisturbed. We need to ensure they receive long-term and large-scale financing to accelerate the restoration and protection of these underwater wonders.” https://www.youtube.com/watch?v=1sEISirUSn0 “We need to protect and restore seagrass whilst supporting the continuation of sustainable human activities that occur amongst or depend directly upon seagrass ecosystems”, said Dr Leanne Cullen-Unsworth, Chief Executive Officer and Charity Co-Founder, Project Seagrass. “We need to do this now, as a connected global community. This program helps to deliver this.” “Seagrass meadows are the powerhouses of coastal seas providing a nature-based solution to climate change, said Dr Claire Evans, Biogeochemist, the UK’s National Oceanography Centre. “They have been neglected for decades, which has led to their large-scale degradation and loss. This program exemplifies how we can turn that loss into an opportunity for environmental renewal through large-scale restoration.” In coordination with Project Seagrass, a team of volunteers from Deloitte and Climate Impact Partners helped harvest seedlings from a healthy seagrass meadow for the recovery program.
With data from the Copernicus Sentinel-2 mission, researchers have revealed seasonal variations in intertidal seagrass across Western Europe and North Africa. As a key indicator of biodiversity, these new findings offer valuable insights for the conservation and restoration of these vital ecosystems. The intertidal zone is the area where the ocean meets the land between high and low tides, and here seagrasses can form extensive meadows. These flowering marine plants provide critical habitats, acting as shelter, nurseries, and feeding and spawning grounds for a diverse range of birds, fish and invertebrates. Beyond their ecological importance, seagrass meadows also stabilize sediments and protect coastlines from erosion. Monitoring the occurrence, extent, condition and diversity of intertidal seagrass as a key biodiversity variable is essential for assessing the overall health of local ecosystems. Current global estimates of seagrass coverage do not differentiate between seagrasses in the intertidal zone and those in the subtidal zone, which remain submerged below the sea surface. However, a recent paper, published in Communications Earth & Environment, details how a team of scientists used high-resolution imagery from the Copernicus Sentinel-2 mission to demonstrate its ability to map intertidal seagrass meadows and their seasonal changes across continents with consistency and precision. Bede Ffinian Rowe Davies from Nantes University in France and lead author of the paper, said, “Coastal regions, like much of the world, are experiencing rapid and alarming biodiversity loss. To address this, it’s crucial to develop efficient monitoring methods so that timely and appropriate action can be taken to preserve delicate ecosystems. “Using data from Sentinel-2 within the BiCOME project, we were able to reveal significant seasonal variations in intertidal seagrass. The peaks in extent shifted by as much as five months—challenging previous assumptions that there was little or no seasonal fluctuation.” The satellite images below illustrate changes in intertidal seagrass cover in the Bay of Bourgneuf, located north of the Bay of Biscay, off the western coast of France. The image on the left, from April 2021, shows sparse intertidal seagrass, while the image on the right, from September 2021, reveals abundant growth. Victor Martinez-Vicente, BiCOME project principal investigator, noted, “This study demonstrates the potential of satellite observations to track changes in the extent of natural coastal ecosystems, providing valuable insights for indicators in the Global Biodiversity Framework. Further research is needed to develop long-term satellite-based monitoring systems and datasets to support global progress toward achieving the framework goals.” ESA’s Marie-Helene Rio added, “These new findings clearly demonstrate the value that Sentinel-2 can bring to monitoring intertidal seagrass. We now believe that these intertidal meadows behave differently to the type of seagrass that spends most of its life submerged by seawater. This suggests that previous estimates, which grouped the two types together, could be misleading. The research paves the way to further monitoring and assessment of intertidal seagrass meadows using Sentinel-2 data.” The Sentinel-2 satellites each carry a multispectral imager that takes high-resolution images of Earth’s land, islands, and inland and coastal waters. And with a large swath width of 290 km, it provides these images in 13 spectral bands with resolutions of 10 m, 20 m and 60 m. The third Sentinel-2 satellite, Sentinel-2C, was launched on 5 September 2024, and has already delivered its first images of Earth.

The Seagrass Ocean Rescue North Wales programme relies on the commitment and enthusiasm of local volunteers. We spoke to regular volunteer Neil about his experiences of volunteering as part of the programme. Volunteer Interview Tell us a little bit about yourself: I grew up in North Wales, then moved around a lot during a career in the automotive industry. After Covid, there was an opportunity to step out and do something different, so it was time to do things I wanted to do rather than had to do. How did you first get involved with the seagrass restoration community project? I’d seen the team operating in Porthdinllaen , read about it, and started to preach about it to anyone that was unfortunate to be in hearing range! Then there was a stroke of luck and I managed to inflict myself upon the boat crew for a few days. What are your hopes for this restoration work? That the word spreads, that more people who don’t mean to negatively affect the environment can learn not to, and that I can keep visiting the areas that we are developing and planting to see them flourish and provide a starting base for more wildlife to move in. It’s great to see how quickly nature can respond, given a chance. I’ve learnt that it’s very subtle changes we make that can help or hinder the natural environment. What inspired you to get involved, what drives your commitment to this cause? I’d just semi-retired, had wandered past the boat team working in Porthdinllaen, did some reading, started to tell others about it, then it was a lucky break to be involved in one of the boat teams. Then it just got out of control from there really! I go snorkelling, boating, and diving and I get frustrated when I see the natural environment being needlessly abused, so this is just one way to try and stop that. The amazing areas of the world provide lots of fun, inspiration and happiness for so many people, sometimes the consequence is pressure on the very thing we go to see, by providing more of those areas then it’s good for everyone. What does it mean to you to spend time in nature, what do you feel nature provides you with? It’s great to see how quickly nature can respond, given a chance. I’ve learnt that it’s very subtle changes we make that can help or hinder the natural environment. What seagrass restoration activities have you taken part in? So far, planting both seeds and shoots, harvesting new seeds and monitoring. Learning from the different team members, chatting with ambassadors and meeting other people that are getting involved. What part of this restoration work are you most proud of? I think it’s the planting, because when we go back to monitor progress and after only a few months we see that nature has already started to move in, then that’s a good thing. The Seagrass Ocean Rescue Project is managed by WWF, in partnership with Project Seagrass, the North Wales Wildlife Trust, Pen Llŷn a’r Sarnau Special Area of Conservation (SAC) and Swansea University. The project is made possible with support from funders that include the National Lottery Heritage Fund, Garfield Weston Foundation, and the Moondance Foundation.

An invasive species of seagrass has been on a steady march across the world, taking over ecosystems well beyond its native waters of the Red Sea, Persian Gulf and Indian Ocean. Scientists have long wondered when it would reach the waters off the coast of Florida. Florida International University scientists say that day has arrived. Florida International University marine scientist Justin Campbell has positively identified Halophila stipulacea growing in Crandon Marina and nearby areas of Biscayne Bay. It is the first time this non-native species has been found in waters along the continental United States. The study appears on the preprint server bioRxiv. “I think this species could pose a considerable threat,” Campbell said. “There are several reports of it being able to outcompete native seagrasses in other areas across the Caribbean. It is plausible that this could also be true for seagrasses here in South Florida.” A marina worker first noticed the seagrass last month and reached out to Campbell, who conducted tests to determine the species. Halophila stipulacea first started spreading its distribution with the opening of the Suez Canal in the late 1800s, hitching rides on the anchors and other parts of boats. By the early 2000s, it was found in the Caribbean. Field photographs of H. Stipulacea inside Crandon Marina (Key Biscayne, Florida) (a,b). Close-up detail of samples collected inside the marina, structure and leaf cross veins (c,d). Credit: Matthew White (a,b) and Justin Campbell (c,d). Healthy seagrass meadows are vital for healthy oceans. They are nursery habitats for commercially and economically important fish as well as shrimp, stone crabs, scallops and other crustaceans and shellfish. Seagrasses are a primary food source for sea turtles, manatees and other marine herbivores. And for the health of the planet, seagrasses are really good at sucking carbon emissions out of the air and storing that carbon long-term. While scientists are still working to understand possible impacts from the invasive species entering waters around the U.S., early research suggests some fish species may avoid the shorter seagrass when scouting nursery locations and local sea turtles in the Caribbean avoid eating the invasive seagrass, preferring native species as part of their regular diets. While most species of seagrass are on the decline from warming waters and other human-induced impacts, Halophila stipulacea has the unique ability to grow quickly and adapt to different conditions including salinity levels, temperature and light availability. Just a small piece can float through water and grow. Once it settles into soil, it can take hold easily and grow at a variety of depths. While most seagrass species require shallower depths to attain sunlight, Halophila stipulacea has been observed flourishing at depths of 60 feet or more. “The arrival of yet another invasive species to Florida is a reminder that all of our earth is interconnected and that human actions have the power to change the planet, for good or bad,” said James Fourqurean, co-author of the research and director of the Coastlines and Oceans Division in FIU’s Institute of Environment. Fourqurean has studied seagrasses, especially those in Florida, for more than 40 years. A foremost expert, he is one of the lead scientists in the International Blue Carbon Working Group, as well as scientific representative to the International Blue Carbon Policy Working Group—both dedicated to the recognition and preservation of seagrass meadows, mangroves and tidal salt marshes as critical contributors to slowing the rise of CO2 in the atmosphere. “Given the importance of seagrasses to a healthy South Florida, we now need to do what we can to limit the spread of this invasive species and be wary of disruptions to the natural order it may cause,” Fourqurean said. Stipulacea has a very different appearance and structure than the native seagrasses in South Florida and throughout the Caribbean. At least 19 Caribbean islands have reported this seagrass growing in nearby waters and, in some cases, overtaking meadows of native grass. “We don’t know whether Stipulacea provides similar ecological benefits as compared to our native species,” Campbell said. “Our seagrass meadows here are some of the most pristine and well-protected in the Western Hemisphere. They are iconic and emblematic. We certainly don’t want to lose them.” So how long has this non-native species been in South Florida? It is hard for Campbell to say, but based on the current distribution, he believes it first started taking root several years ago. It had gone unnoticed because, to the casual observer, it can be difficult to distinguish from native vegetation, he said. Crandon Marina can accommodate medium and large sized sailboats, likely capable of travel to and from areas where Stipulacea is well-established. This is one possible and likely way the non-native seagrass reached Biscayne Bay. With other large marinas in the region, Campbell said surveys and monitoring should be expanded now that this invasive species is confirmed to be in South Florida. More information:Justin E.

Restoration Forth aims to restore seagrass meadows and native oysters into the Firth of Forth, to create a healthier coastline for people and nature. Find out more about the project here. Restoration Forth August Fieldwork | Seagrass highlights from Orkney The seagrass team are not long back from Orkney, where they spent just under a month conducting this year’s seagrass seed harvest as part of the Restoration Forth August fieldwork. Many snorkel sessions were conducted to harvest seed baring reproductive shoots to further drive our restoration trials here in the Forth. Despite the fair-weather conditions and ample snorkel sessions the team have returned with slightly less material than what was collected last year. However, this should not prohibit our restoration ambitions next spring. Whilst in Orkney the team were able to deliver a range of community events, which included participating in this year’s Stromness shopping week. MSPs Ariane Burgess and Liam McArthur joined Restoration Forth’s community snorkel sessions in Orkney where, along with members of the local community, they met the team and learned about how projects like Restoration Forth aim to restore nature and drive future restoration. Increasing knowledge amongst elected representatives about the importance of these habitats is an important part of highlighting the need for the Scottish Government to bring forward legislation to protect and restore Scotland’s nature. In addition to the seeds collected from Orkney, the team will be visiting the Moray Firth. In the first week of September the team will meet up Mossy Earth and Moray Ocean Community to organise an intertidal seagrass pick. This community and knowledge exchange intends to bring our projects closer together and further our collective knowledge. Intertidal seeds gathered from the Moray coast will provide insights into whether there are differences in germination rates between subtidal and intertidal seeds. Newhaven Oyster Mural is going ahead! We are pleased to announce that the Oyster Mural planned for the Heart of Newhaven’s Anchor building has been granted planning permission. Thank you to everyone who was involved in workshopping ideas for the design, including Victoria Primary school. Natasha Russell, Edinburgh based illustrator and mural artist, has created the design to incorporate many of the local species that people expressed an interest in. The mural aims to engage passers by with the wonders of local biodiversity. Captured within the oyster shells in the design, there are scenes and stories that represent the cultural importance of oysters in the Forth, including the fishing of, and release of oysters into the water. It celebrates the oyster’s return to the Forth and their key role within the local ecosystems, whilst acknowledging the deep local history with the oyster fishing trade. The mural will be painted in September. Come along to the Doors Open Day at the Heart of Newhaven on the 28th September at 11.00, to see the unveiling of the mural.
Read our fieldwork notes from our summer seagrass seed collection: North Wales Seed Collection A brilliant start to our annual seed collections, with summer finally arriving right on time! The weather has been fantastic, with underwater visibility not too far off 10m, and not a drop of rain so far… Here’s hoping it holds out until next week! It’s been a very busy start, but here’s just a few of the highlights: Day 0.5 – Day 1 | Saturday 27th – Sunday 28thAfter arriving in good time on Saturday afternoon and launching Gwen with no troubles, the team spent Sunday morning moving all our equipment into Cabin Gryff and Gwen, before setting up the temporary seed storage tanks. We then went through a few rescue refreshers. The dive team set up the keep nets on the RNLI buoys, which will be home to all the seeds collected by both teams during the trip. The team practiced diver recovery drills, before finishing the day with a first seed collection dive The snorkel team went out seed collecting, but having missed the morning Low Tide, learnt the hard way that duck diving for seeds is rather tiring! Day 2 | Monday 29thThe snorkel team, led by Amel, started the day as they will throughout the trip, with seed tank water changes! They then had a far more successful seed collection snorkel, bagging plenty of seeds. Charles has also started his VR footage collection using the 360 camera, capturing some fantastic images of the meadow. Fingers crossed some fun species ‘take the bait’. Meanwhile, Manning has been sampling sites as part of his Masters project, with the help of Richard, who has been out flying the drone round the LLyn, taking advantage of the clear skys! The dive team completed three meadow health surveys, which will help us assess the current state of the Porthdinllaen meadow, and monitor any potential impact of our seed collections going forward. We were joined by Katie Dubois, a lecturer at Bangor University, who helped with our afternoon seed collection dives. The meadow is bursting with seeds, so we should be set for a good collection! Day 3 | Tuesday 30thThe snorkel team had their best collection yet today, and were in the water battling the cold for a good 4 hours! Another big haul of seeds! The dive team ticked off half the mechanisation surveys, which will help wrap up the mechanisation project. We then went seed collecting, whilst dropping down Charles’s VR camera to catch some footage. Day 4 | 31st JulyWe arrived early to set up our stand ready for our FIRST volunteers. We also welcomed our Ambassador Miranda Krestovnikoff. Day 5 | 1st AugustOne quick water change later and we’re back in the water! We started by taking the VR camera out to get a series of snorkeling shots through and coming out of the seagrass meadow before placing down for an hour-long shot. We then proceeded to pick seeds joined by Leanne and Miranda. Once again, a perfect dive, with pristine waters and life abundant. To end our day off we did a quick evening session with the VR camera. It was an amazing shoot with many fish species and a perfect way to end the day. Day 6 | 2nd AugustToday we rested. Day 7 | 3rd AugustAfter an excellent rest day we proceeded to begin our week of volunteer seed collections. We started the day by transporting volunteer divers off before getting everything prepared for the snorkel volunteers. The day went brilliantly, with all snorkelers/waders returning, smiling and with happy faces. We chatted, and met so many fantastic people! Day 8 | 4th AugustOnce again, Amel and Emma were up bright and early to transport volunteer divers before joining the rest of the day. We joined WWF for a Philanthropy Day, a day for all of our donors and backers. The day started with a quick meal before returning to set up all equipment and stand ready to take our donors for a quick snorkel. All came back with smiles and a successful day all around. The dive team been out every day for seed collections, seed collections, seed collections! Jake Davies and Neil Shone have joined throughout, and we had Dr Katie Dubois (Bangor University) with us again on Sunday! Day 9 | 5th AugustA windy and rainy storm has scarpered all snorkelling activities! We’ve all but finished the mechanisation trial surveys (there’s a few buoys missing so we may have to return and drop shot lines on the coordinates). The best news is there are still lots of seeds coming up after every dive! We’ve all but filled three keepnets (the total we managed last year), so hopefully we should be well on target for 1.5 million by the end of the trip! We’ll be out to install another keepnet tomorrow. Volunteers divers have also been joining since Saturday, with great feedback from all. Day 10 | 6th AugustToday was the first of our snorkel and wading volunteering sessions and it went really well! We were joined by 51 volunteers including WWF, Iwan Rheon, the Crown Estate, North Wales Wildlife Trust (with their Youth Forum and Interns) alongside lots of Project Seagrass volunteers! BBC joined us and interviewed Leanne and Rich! The dive team carried out two more dives (for me at least) with lots of seeds collected. We are into our fourth keepnet of seeds, which exceeds last year’s total already, and we’re hopeful the reproductive shoots are bearing more seeds than previous years too. Day 11 | 7th AugustCharles, Andrew, and volunteer Antje headed to Porthdinllaen this morning to capture more footage for the VR Project while Andrew and Corinne headed to Hafan y Mor to install a seagrass information sign. Another successful snorkel and wading volunteering session delivered in the afternoon/early evening. Over 30 volunteers joined us including representatives from the Crown Estate, WWF, and North Wales Wildlife Trust. BBC Radio Cymru joined to interview members of the
Seagrass meadows are essential for the health of our oceans. They provide vital habitats for marine life, improve water quality, and store significant amounts of carbon. Unfortunately, these vital ecosystems are in decline. Here at Project Seagrass, we are on a mission to restore seagrass meadows to help create a healthier world and protect against the impacts of climate change. To achieve this, we are partnering with Tandem Ventures to develop an underwater seagrass seed harvester to help us to more efficiently collect seagrass seeds and scale up the restoration process. In order to do this, we need your help. We need to raise £30,000 to design, develop, and test this innovative new technology. Supporting our Crowdfunder will make seagrass restoration faster, more efficient, and scalable. Donate Today The Problem Currently, seagrass seed collection relies on divers using scissors – a slow and labour-intensive process. This bottleneck limits large-scale restoration efforts. We need to invent a new and radically better method this summer, while the seagrass is producing seeds. Time is ticking! Our Solution: The Underwater Seagrass Seed Harvester Key Features Automated Operation: Operates far more efficiently, reducing the need for manual labour. Efficient Collection: Gently harvests seeds without damaging the seagrass beds. Boat-Towed Design: Causes minimal disturbance to the seabed while covering large areas quickly. Adjustable: Key elements of the design can be adjusted to most efficiently collect Seagrass seeds in differing environments. Open-Source Design: Thoroughly documented and shareable plans, allowing replication and application worldwide. Join Us in Making a Difference We need to raise £30,000 to make this vision a reality.

Scientists from The University of Western Australia have partnered with Indigenous rangers on a seagrass restoration project in Gathaagudu (Shark Bay) to help moderate climate change and conserve biodiversity. Dr. Elizabeth Sinclair and Professor Gary Kendrick, from UWA’s School of Biological Sciences and Oceans Institute, were co-authors of the paper published in Ocean & Coastal Management. “Solutions that integrate western science and Traditional Ecological Knowledge are key to improving restoration outcomes,” Dr. Sinclair said. Researchers partnered with Malgana Aboriginal Corporation Rangers on a program that included On Country workshop-based knowledge sharing in north-west Western Australia, with a focus on seagrass restoration. Malgana Elder, Auntie Pat Oakley said managing and caring for a living and dynamic Country are at the heart of well-being for all Indigenous Peoples. “The global rate of seagrass decline continues largely due to human activities, including the widespread impacts from climate change,” Professor Kendrick said. “Reversing this decline by restoring seagrass ecosystems and the benefits they provide is challenging and can take decades, even when human impacts are reduced.” The program found with the right resourcing and logistics, there are opportunities to support training workshops that develop expertise in seagrass restoration activities in Shark Bay. Sean McNeair, Malgana man and ranger coordinator, said field-based restoration workshops helped people reconnect with Country through two-way knowledge sharing. “We need to empower the Malgana Aboriginal Corporation Rangers and local Indigenous-led businesses to schedule restoration activities that help build seasonal local economies and increase the ability to restore seagrass at larger scales,” Dr. Sinclair said.
