Pioneering Eco-Moorings to Safeguard Studland Bay's Seahorse Haven Project Overview In a groundbreaking collaboration with the National Trust and The Seahorse Trust, Apex Diving & Marine led the installation of hundreds of innovative "eco-moorings" in Studland Bay, Dorset—the first of their kind in the UK. This ambitious project, part of the Studland Bay Marine Partnership (SBMP), aimed to protect the bay's fragile seagrass meadows, a vital breeding ground for the endangered spiny and short-snouted seahorses. Traditional boat anchors had long scoured the seabed, devastating these biodiverse habitats. By deploying eco-moorings—helical screw anchors connected to buoys via flexible elastic ropes—we minimized seabed disturbance, allowing seagrass to regenerate and marine life to thrive. Studland Bay, designated a Marine Conservation Zone (MCZ) in 2019 after over a decade of advocacy by The Seahorse Trust and partners including the University of Southampton, spans six nautical miles along the Dorset coast. Home to Dorset's largest seagrass meadow, it supports protected species like seahorses, undulate rays, pipefish, and commercial fish such as sea bream and bass. Our installation marked a pivotal step in the SBMP's 10-year strategy to balance conservation with sustainable recreation, ensuring the bay remains accessible for boaters while fostering ecosystem recovery. The Challenge Studland Bay's popularity as a sheltered boating destination has come at a cost. Rising visitor numbers—over 1.5 million annually to the area managed by the National Trust—led to increased anchoring, which uprooted seagrass and fragmented habitats. Seagrass meadows, the only marine flowering plants in UK waters, are global carbon sinks, capturing 10% of oceanic carbon burial and producing up to 10 tonnes of oxygen daily in Studland alone—enough for 10,000 people. Their decline threatened the spiny seahorse (Hippocampus guttulatus), whose primary UK breeding ground is here, alongside the short-snouted seahorse (Hippocampus hippocampus). Surveys showed dwindling populations, exacerbated by climate change and habitat loss. The SBMP, formed in 2021 by The Seahorse Trust, boatfolk marinas, the National Trust, Royal Yachting Association (RYA), and others, introduced a Voluntary No Anchor Zone (VNAZ) in 2021. However, without alternatives, compliance was challenging. Eco-moorings were the solution: their 16 cm seabed footprint allows seagrass to grow unimpeded, unlike chain moorings that scour up to 10 meters wide. Funding challenges persisted, with installations costing £240,000 for the full rollout, sourced from grants like the Marine Management Organisation's Fisheries and Seafood Scheme (£186,000), crowdfunding (£66,000), and donors including The Crown Estate, SEA LIFE Trust, and The Pig-on the Beach hotel. Our Solution Apex Diving & Marine was selected as the lead contractor for this pioneering installation, leveraging our expertise in underwater engineering and marine conservation. We designed and deployed eco-moorings using helical screw anchors driven deep into the sediment for stability, paired with elastic risers that absorb tidal movements without chain drag. These were the UK's first large-scale eco-mooring array, installed across the VNAZ from Handfast Point to Middle Beach. Our team conducted precise seabed surveys using side-scan sonar to site moorings optimally, avoiding sensitive zones. Installation involved certified divers in challenging conditions—currents up to 2 knots and visibility as low as 1 meter—ensuring zero environmental impact. We collaborated closely with SBMP partners for compliance with MCZ regulations and integrated public education, including signage and boater briefings. Results and Impact The project has been a resounding success, transforming Studland Bay into a model for UK marine conservation. Key outcomes include: Habitat Recovery: Seagrass coverage increased, with meadows regenerating around moorings. The small footprint has enabled denser growth, boosting biodiversity. Seahorse Surge: Volunteer surveys by The Seahorse Trust reported a "monumental" rise, from rare single sightings pre-project to 33 spiny seahorses in one 2025 dive—described as "spectacular" by experts. Peak sightings hit 21 in a single dive in 2020, with numbers doubling post-installations. Boater Adoption: Over 58% of surveyed users expressed interest in conservation, with high VNAZ compliance. Eco-moorings reduced anchor damage by providing 100+ spots, accommodating peak summer traffic. Broader Ecosystem Benefits: Enhanced nursery grounds for fish stocks, carbon sequestration, and oxygen production. The bay now exemplifies "nature-positive" recreation, praised by figures like Chris Packham. Maintenance costs (~£100,000 annually) are offset by fees and donations via the National Trust's Studland Bay Appeal, ensuring sustainability. Conclusion Apex Diving & Marine's role in this landmark project underscores our commitment to innovative, eco-friendly marine solutions. By installing the UK's first eco-moorings, we've not only protected Studland Bay's seahorses and seagrass but also set a blueprint for global conservation efforts. As Neil Garrick-Maidment of The Seahorse Trust noted, these moorings "bring space and time for recovery," breathing new life into dwindling populations. We're proud to partner with the National Trust and SBMP, proving that collaboration can harmonize human enjoyment with nature's resilience.
