Scientists from the Tokyo University of Marine Science and Technology are already planning the second phase of their ambitious goal of artificially restoring the largest coral reef in Japan. Damage by starfish and rising temperatures have reduced coral densities by over 80% in Sekisei Lagoon where the cultured stony corals are being planted. Although only a third of the 5600 colonies planted in 2006 survived, the researchers believe that with lessons learned they should have much better success with the 6000 colonies being planted on the seabed this month.
