The royal initiated forestry projects (the Kun Mae Kuang Project -- Chiangmai, the Huay Bang Sai Project -- Mukdahan, the Phupan Project -- Sakon Nakhon) emphasize deforestation, conservation and rehabilitation of watershed forests. The rehabilitation includes the planting of various tree types that would maintain humidity and emit more oxygen, the wet fire-break forests created by check dams, as well as the conservation of swamp and mangrove forests.
