Species Info

  • Rhizophora mucronata
  • Rhizophora apiculata
  • Avicennia officinalis


  • The mission of this project is to rehabilitate coastal ecosystems, reforest areas of abandoned prawn ponds, fight against global warming, and create local jobs for community members in Indonesia.
  • This project was started in 2004 by Akira Yamamoto, president of the PT. Yamamoto Asri and YL Investment Company Ltd. who had the goal of replanting 0.1 million hectares of degraded mangroves near the coast of Bantam Island, Indonesia.
  • Since 2005, over 4000 workers have been employed to plant about 17 million trees over an area of 13,450 ha.
  • Rhizophora mucronata and Rhizophora apiculata were the main species planted; Avicennia officinalis was introduced to rehabilitate the abandoned prawn culture pond.
  • The Rhizophora mucronata trees planted along the Temoyong Islands have grown around 2m in the 3-4 years since planting.
  • Future plans include turning the project into an AR-CDM project so that the project can gain funding through emissions reductions and not depend solely on private investment.
  • Future plans to continue mangrove planting on the scale of 0.1 million hectares.
