Seagrasses are flowering plants that live in the shallow, sheltered areas of our coast. These sensitive plants are different from seaweed and grow bright green leaves forming dense underwater meadows. These meadows are full of life, supporting thousands of marine species, producing oxygen, storing carbon, stabilising our coastlines and keeping our ocean clean and clear. Yet, they are globally threatened and are facing significant loss around the world.

Since the late 19th century, it is estimated that one third of our worlds seagrass meadows have disappeared. It’s vital we save what we have left and restore what we have lost.

Saving seagrass means saving our seas. We need to protect and restore seagrass whilst supporting the continuation of sustainable
human activities that occur amongst or depend directly upon seagrass ecosystems. We need to do this now, as a connected global community, using and sharing knowledge and expertise, recognising, and espousing the vast body of largely untapped local ecological knowledge and empowering action from the local to international scale.

Since 2013, Project Seagrass has been committed conserving seagrass ecosystems to ensure that the benefits they provide people and planet are sustained now and for the future.
By bridging community, research and action, we can save the world’s seagrass.

In September 2025, Project Segrass welcomed Anya, Dylan, Will, Grace, Iestyn, Jasper, and Ewan as our interns for the 2025-26 academic year. In this Q&A our interns share their experiences and highlights from their first three months as interns with Project Seagrass. What have been the highlights from your internship
Bonefish & Tarpon Trust have selected Project Seagrass’ Chief Conservation Officer and Co-Founder Dr. Benjamin Jones as the recipient of the inaugural Davidson Science Award. The award has been established to recognize transformative scientific contributions to flats conservation, coastal inshore waters utilized by anglers which are dominated by seagrass meadows.
In a new blog series, our Conservation Trainee Abi David explores some of the amazing creatures that call seagrass meadows their home. Sea snails are a hugely diverse group of marine gastropod found in all over the world. There is such a vast range of different colours, sizes, diets and
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.
