Dorset Seagrass Meadows Recover 93.6% After Eco-Moorings Replace Anchors

A new study from Studland Bay in Dorset shows seagrass meadows healing quickly after traditional chain moorings were replaced with eco-moorings. Over four years, bare patches in the primary trial zone shrank by 93.6%, a recovery rate of about 57 square meters per year. The eco-moorings use a helical screw anchored deep in the seabed and an elastic rode, eliminating the dragging chains that scoured the seagrass. Seagrass is a major blue carbon sink, sequestering CO2 faster than tropical rainforests, so this recovery matters for climate mitigation as well as biodiversity. The study provides clear evidence that removing physical disturbance can restore degraded marine habitats relatively quickly. It offers a scalable, low-cost model for coastal managers balancing recreation and conservation.
