Seagrass meadow restoration in the United Kingdom

Loch Craignish, United Kingdom
Seagrasses are the only flowering plants that can live underwater. Just like plants on the land, they have leaves, stems, roots, and photosynthetic activity. The plants’ long but strong leaves form dense meadows under the sea. Loch Craignish in Scotland has 10 small seagrass meadows and there are 80 hectares of mud where we think seagrass can be restored. With this seagrass meadow restoration project, in cooperation with Seawilding, we are trying to rebuild damaged seagrass meadows and expand the meadows already existing. This is vital, becau...Read more

Seagrass transplantation area, May - July 2024

In 2024, between May and July (the planting season), and with the help of over 40 volunteers, we harvested, processed, and replanted over 8,000 seagrass plants - rhizomes - in Loch Craignish over an area measuring approximately 485 square meters of seabed. We focused on a single area, Dun Mhuilig Bay, adjacent to an existing seagrass meadow, where ...Read more

Seagrass transplantation area, March - July 2025

With the help of 47 incredible volunteers from the UK, Europe, and beyond, our local team in Scotland transplanted 20,000 shoots over a five-week sprint this spring, potentially creating 2,600 m² of new seagrass meadow. That’s a 300% increase from last year’s efforts. They're growing, literally and figuratively. In 2024, we often planted bundles o...Read more
