New eco-moorings help seahorse habitats heal off Dorset coast
A scientific study shows that new eco-moorings installed off the Dorset coast since 2021 are helping damaged seagrass meadows recover.
Study tracks seabed recovery progress
Researchers analysed five years of monitoring data to track changes across thirty-nine damaged areas. Sonar surveys and historical satellite imagery revealed that bare patches in the seagrass shrank significantly over time. In the trial area where ten new moorings were placed, the size of these scars dropped by an average of 93.6 percent between 2021 and 2025.
Recovery rates exceed initial expectations
The rate of healing was around fifty-seven square metres each year in the protected zones. David Brown, who chairs the partnership steering group, stated that the impact has surpassed what was expected. He described the findings as incredibly exciting for the local marine environment.
Comparison with old moorings
A second study area kept traditional chain moorings until 2023 to serve as a control group. The research team noted that scars in this location remained visible while the new sites improved rapidly. This comparison highlights the effectiveness of switching from heavy chains to lighter eco-moorings.
