Membership success stories

We work tirelessly to protect our ocean for the future and your membership contribution helps determine the scale and scope of our efforts. With your continuous support, we can continue to fund vital marine conservation projects which will preserve the health of our oceans for generations to come.

Restoring Seagrass

By using innovative solutions to safeguard ocean biodiversity, we've collectively given space for rewilding to take place. We’re working with local communities to protect the seabed. In the south of England, our project has driven a 212% increase in seagrass cover following the installation of protective measures, benefitting wildlife, people, and planet.

Reintroducing Oysters

We’re reintroducing native oysters to Scottish seas. Oysters play a vital role in supporting ocean recovery, forming reefs which provide habitat for marine life, and filtering up to 200 litres of water per day. With an 85% global decline in oyster numbers, we’re working to reverse this trend through pioneering projects.
