The agricultural function of the native reserves should be declining since Taiwan became a member of the World Trade Organization. Owing to the abundant landscape resources in some reserves and increasing demand on outdoor recreation, it has been proved by relevant studies as a new survival way for native people to develop leisure and recreation business in terms of their reserves' land uses. However, it is possible to threaten the sustainable management of the ecotourism due to a lack of knowledge and experience in activity programming. This is the basic concern of this article. If the relevant government agencies have some training programs for native people to carry out their ecotourism business, the curricula design for the training programs may refer to the results and suggestions of this article. An integrated study results from Tanaiku ecological park at Arlishan village, Chiayi county, Songher community at Hopin village, Taichung county and Pagou Lass reserve, Nantou county were used as information in this study. This article is a primary exploration of the principles of ecotourism programming and planning skills for the reference of ecotourism providers. Hopefully this primary exploration would inspire those who are interested in this issue to promote sustainable ecotourism in the native reserve areas.
