What is it about?
We studied the feasibility of restoring eelgrass meadows using seeds in the Swedish west coast. We found that seed predation from crabs, seed transport by currents, and bioturbation by lugworms were the main causes of seed loss, while light availability and physical disturbance affected shoot development. We also identified optimal conditions for long-term seed storage and found that covering the seeds with a layer of sand increased seedling establishment. However, high seed-loss and shoot mortality pose a challenge for large-scale restoration using seeds.

Why is it important?
This study provides insights into the challenges and potential solutions for restoring eelgrass meadows using seeds, particularly in high-latitude regions with long winters. The findings can inform the development of effective restoration strategies and improve the success of restoration efforts.
Perspectives
Eelgrass restoration is crucial for the conservation of marine biodiversity and the provision of important ecosystem services. The challenges and potential solutions identified in this study highlight the importance of considering the complexities of the restoration process and the need for interdisciplinary collaboration in developing effective restoration strategies.
