What is it about?
Seagrass meadows and their associated biodiversity have declined globally. We conducted a restoration trial of eelgrass in Sweden to test the role of patch size in driving faunal colonization. We found rapid faunal colonization following the transplantation of eelgrass shoots in all plots, with both invertebrate densities reaching 50-80% of the reference meadow after only one growing season. Biodiversity and functional diversity were similar among different planted plots, indicating that smaller patches can be as effective for promoting biodiversity as continuous patches, with reduced costs and fewer shoots required.

Why is it important?
Our study provides insight into the effectiveness of different patch sizes in driving faunal colonization in eelgrass restoration projects. Our findings show that smaller patches can be just as effective for promoting biodiversity as continuous patches, which has practical implications for the design and implementation of seagrass restoration projects worldwide.
Perspectives
As a marine biologist, I find this study particularly interesting because it highlights the potential for small patches of eelgrass to have a significant impact on biodiversity in restoration projects. This emphasizes the need to carefully plan and monitor restoration projects, considering the effectiveness of different patch sizes and the dynamic nature of seagrass ecosystems. Our findings provide important guidance for the development of more efficient and cost-effective restoration strategies for seagrass meadows.
