We developed a novel and scalable seagrass restoration technique, in which seagrass seeds are mixed with sand and applied in a thin layer upon a degraded seabed.…
Scotland sand capping
We successfully executed sand-capping with seagrass seeds to restore seagrass at scale in Scotland. 100,000 eelgrass (Zostera marina) seeds were distributed, in combination with sediment nourishment, across an area of 1,000 square meters. The project is executed in collaboration with a local organisation, Seawilding, that will monitor the establishment and survival of the seedlings.

In this pilot project, we test the developed sand capping technique in Loch Craignish, Scotland. We applied sandy sediments with optimal densities of eelgrass seeds onto a degraded, muddy seafloor, via a modified spray-pontoon. By sand capping the seabed, we aim to create more favourable conditions for the dispersed seagrass seeds to thrive and enhance biodiversity by reducing resuspension, increasing light availability and temporarily excluding seed predators.
To evaluate this method’s effectiveness, our local partner Seawilding will closely monitor the site over the next year, tracking germination and seedling development.
