Seagrass Regrows in 5 Years Thanks to Eco-Moorings
21 Sep
Summary
- Eco-moorings helped Dorset's seagrass meadows recover significantly.
- Bare patches in seagrass shrank by 94% in areas with eco-moorings.
- Seagrass recovery boosts populations of seahorses and other marine life.
Seagrass meadows in Studland Bay, Dorset, are showing significant recovery thanks to the introduction of eco-moorings. These specialized anchors, installed in 2021, have drastically reduced the seabed damage previously caused by traditional anchors.
Research indicates that in areas with eco-moorings, bare seagrass patches decreased by an average of 94% between 2021 and 2025. This rapid regeneration highlights the habitat's capacity to recover when physical disturbance is mitigated.
The positive impact extends to marine life, with observed increases in seahorses and other species like eels and crabs. This restoration effort provides a promising model for protecting and reviving seagrass meadows in other busy marine areas facing similar pressures globally.
Eco-moorings work by using a helical screw that secures to the seabed, connected to a buoy via an elasticated riser. This system prevents scouring as tides change, safeguarding the delicate seagrass ecosystem. The Studland Bay Marine Partnership hopes these findings will encourage wider adoption of eco-mooring technology.
