Coral reefs play a crucial role in underwater ecosystems, providing habitats and the foundation of food chains for numerous marine species. In the waters of Hainan Province, researchers have been diligently "planting" corals underwater for years.

Since 2004, the Hainan Boundary Island tourist area has been working with the local authorities to implement a series of coral conservation programs, including coral reef transplantation and other marine ecological restoration projects.

On World Oceans Day, an underwater coral transplant event was also held in the waters surrounding the area. This initiative not only supports marine ecological restoration, but also demonstrates aspects of the coral conservation work in the area and its achievements to tourists participating in diving projects.

Thanks to years of dedicated conservation efforts, the coral cover in the waters around Boundary Island has increased significantly, providing a wider habitat for a growing number of marine species.
