More than 430 seagrass shoots have been found in Cornwall’s Fowey Estuary, offering fresh hope for a restoration project that appeared uncertain earlier this year.
Cornwall Wildlife Trust recorded the new growth across 50 patches of seabed during summer surveys. In April, just six seedlings had emerged, raising fears that the trial might not succeed.
A boost for a valuable marine habitat
Volunteers collected seeds from a donor meadow in Torpoint in autumn 2025 and planted them in the estuary. The seeds remained buried over winter before beginning to grow in spring.
The work is part of Seeding Change Together, a partnership between Cornwall Wildlife Trust and Seasalt Cornwall that began in 2022. More seeds are due to be planted in the Fowey and Helford estuaries, with further monitoring planned for spring 2027.
Seagrass meadows provide shelter and nursery grounds for fish and other marine life. They can also help improve water quality, store carbon and reduce coastal erosion. The trust says mainland Britain has lost up to 92% of its seagrass meadows over the past century.
The project has faced setbacks, including algal growth at one Helford site. However, three surviving plants were later found to be spreading.
Why it matters for Britain
The results suggest careful, volunteer-led restoration can help rebuild an important coastal habitat in Cornwall. Healthier seagrass meadows could support marine life, improve water quality and help protect estuaries from erosion.
