Forest ecotourism is an important part of the construction of Hainan International Tourism Island. Forest ecotourism is an important and effective effort to enhance environmental services and local livelihoods in Hainan Province. Investigation and assessment of tropical forest ecotourism resources is the most important step for implementing and promoting tropical forest ecotourism in Hainan Province. Six typical tropical forest ecotourism resources (forest landscape and/or forest community level) in Hainan Province will be selected as demonstrative objects to assess the potential of developing tropical forest tourism. A sound methodology for investigating and assessing tropical forest ecotourism resources in Hainan Province will be developed through reviewing relevant knowledge and best practices and participatory multi-stakeholders consultation process. A comprehensive assessment report on six typical forest ecotourism resources will be published and distributed to interested parties in China. The project originates from the ITTO Thematic Programme on Reducing Deforestation and Forest Degradation and Enhancing Environmental Services in Tropical Forests (REDDES).
