Since 2005, students from the Koh Yao Noi school, working together with the Chiba Environmental Council (Japan), Koh Yao Noi Eco-Tourism Club and with coordination from NACA have endeavoured to restore the environmental damage from the tsunami, and to improve the livelihoods of local people through a variety of initiatives. One of the main activities has been the annual replanting of seedlings of locally occurring mangroves and tropical forest trees to regenerate the damaged areas.
