Seaweed removal project sparks 600% coral regrowth

A citizen scientist-led seaweed removal initiative off Magnetic Island's coast has resulted in a remarkable coral regrowth of up to 600%. Over three years, volunteers cleared macroalgae from experimental reef plots, leading to significant coral rejuvenation and increased diversity. The method, akin to weeding a garden, offers a low-cost approach for reef restoration, particularly in developing nations. The success has prompted plans to expand the project to other locations facing different stressors, highlighting the positive impact of community involvement in safeguarding coral reefs. The Earthwatch Institute-led program will continue on Magnetic Island until at least 2025. (Phys.org)
