A BBC article highlights volunteer efforts to harvest seagrass seeds from the Solent, where the UK has lost over 90% of its seagrass meadows. Seagrass can absorb 35 times more carbon per area than tropical rainforest, making restoration a high-impact natural climate solution. Volunteers collect seeds during low tide, which are then processed and stored for spring planting. The process involves collecting seed-bearing spathes, rotting them in seawater tanks, and storing seeds in cold saline water until spring. The University of Portsmouth supports the science behind this restoration. While small-scale, the project demonstrates a replicable model for coastal carbon removal and habitat recovery. For carbon credit markets, seagrass restoration offers measurable carbon sequestration alongside biodiversity co-benefits, though scaling remains a challenge.
