Five million seagrass seeds are being planted off the Llŷn Peninsula in Gwynedd and Anglesey, in North Wales, with the aim of creating 10 hectares (100,000 sq metres) of seagrass meadow by the end of 2026.
By harvesting seeds from existing meadows of seagrass, the conservation workers can plant and grow more underwater meadows.
The World Wildlife Fund (WWF) are working with the charity Project Seagrass, Swansea University, North Wales Wildlife Trust and Pen Llŷn a’r Sarnau Special Area of Conservation.
Alec Taylor from the World Wildlife Fund (WWF) said: “We see seagrass as this wonder plant because of its ability to fight climate change, to help fish stocks, coastal communities and livelihoods.”
Those running the project hope that local communities will join the efforts to help the sea beds thrive by using the sea in an environmentally-friendly way, protecting the area in which they live for future generations to come.
