Restoration of Seagrass Beds Using Biodegradable Bioplastic-Based Eco-Friendly Planting Frames

Restoration of Seagrass Beds Using Biodegradable Bioplastic-Based Eco-Friendly Planting Frames

The international community aims for carbon neutrality by 2050, recognizing the importance of “blue carbon” in marine ecosystems like seagrass beds. The Korea National Park Service is dedicated to enhancing carbon absorption through the restoration of eelgrass in Hallyeohaesang National Park.

Since 2018, restoration efforts faced challenges with initial transplantation methods showing variable success rates. In 2021, an eco-friendly planting frame using paper egg cartons was developed, but it was inefficient. The following year, biodegradable bioplastic frames were introduced, yet they were too light and restricted eelgrass growth.

In 2023, a new planting frame was created from biodegradable bioplastic with greater density, providing adequate space for eelgrass expansion. This frame was successfully used to restore seagrass beds along the Daegopo coast.
