Clams Plant Seagrass Seeds Underwater
30 Oct
Summary
- Clams naturally burrow, carrying seagrass seeds to the seafloor.
- Project attaches seeds to shells, aiming to restore coastal habitats.
- 10,000 clams will carry 300,000 seagrass seeds this season.
Conservation efforts in Connecticut are employing an inventive strategy to revitalize eelgrass meadows within the Long Island Sound. This project, funded by Restore America's Estuaries, utilizes clams to naturally plant eelgrass seeds.
The method involves attaching eelgrass seeds to clam shells. Once released into the water, the clams burrow into the sandy seafloor, carrying the seeds to suitable locations for growth. This technique offers a more effective way to re-establish these vital underwater ecosystems, which are crucial for sheltering young marine life, preventing shoreline erosion, and enhancing water clarity.
Initial testing began in 2025, and early observations have shown promising growth in eelgrass coverage. Researchers have experimented with different methods to secure the seeds, including rice paper and underwater glue, to ensure their successful delivery and germination.
This season, conservation teams aim to release 10,000 clams, collectively carrying approximately 300,000 eelgrass seeds. While early progress is encouraging, the long-term survival and establishment of these newly planted meadows are still being monitored.
