Why Restore Seagrass?

Seagrasses are the unsung heros of our coastal seas. As much as 92% of the UK’s seagrass has been lost, restoring it is vital for ocean health. Seagrass has huge benefits. It can protect coasts, improve water filtration and plays the following important roles:


Spiny seahorse (Hippocampus guttulatus) female sheltering is meadow of common Eelgrass (Zostera marina). Studland Bay, Dorset, England.

Stablising Sediment

“30 by 2030”

The decade from 2021-2030 has been declared by the United Nations General Assembly in New York as the “UN Decade on Ecosystem Restoration”. This ‘call to action’ was put forward to motivate people, communities and countries across the world to increase the speed at which we are restoring degraded ecosystems. The Bonn Challenge was set in 2011 with a goal to restore 350 million hectares of degraded and deforested terrestrial ecosystems by 2030, but no such challenge has been issued for the marine environment.

The UN Decade of Ecosystem Restoration declaration also coincides with the UN Decade of Ocean Science for Sustainable Development, which aims to reverse deterioration in ocean health.

Our restoration work builds on research led by Swansea University in Wales that has been inspired by the achievements of successful restoration globally

Our approach is simple, its all about underwater gardening to collect, separate and plant seeds. To date we have restored 2ha of seagrass off the coast of Wales, but we have set ourselves the target of 3000ha (30km2) by 2030.

At Project Seagrass we wish to deliver on both of these United Nations calls to action.

YOU can too by helping us plant seagrass!
