This study utilizes quantitative indicators as well as qualitative survey to analyze the use of ethnobotany in North Tsou tribal region situated in the Alishan Township of Chiayi County, Taiwan. In the region, 276 species in 101 families of vascular plants were utilized, including 15 species in 12 families of pteridophyte, 4 speices in 3 families of gymnosperms, 206 species in 72 families of Dicotyledon and 51 species in 14 families of monocotyledon. The ethnobotanic uses were grouped into seven use categories and seventeen items, that is, People's livelihood, Seasonal events, Faiths & customs, Cultural language, Ethnic arts, Everyday life and Others. People’s livelihood was further divided into eleven use items, that is, Food, Weaving, Building materials, Transportation, Pasturage, Fuel, Economic Plants, Agricultural material, Medicine, Hunting & fishing and Entertainments.

Warb. ex Schum. & Laut., and Yushania niitakayamensis (Hayata) Keng f. were among the top three plants of diverse uses. Furthermore, plants of single use items were accounted for 53.26%, while the rest were of multiple use items. Phyllostachys makinoi Hayata, with eighteen use items, is the most popular plant.

As of Use Value index, Phyllostachys makinoi Hayata (3.00) is the most valuable plant, followed by Dendrocalamus latiflorus Munro (2.67) and Calamus quiquesetinervius Burret. (2.67). As of Relative Importance index, Phyllostachys makinoi Hayata (2.00) is the most frequently used species, followed by Dendrocalamus latiflorus Munro (1.56), Calamus quiquesetinervius Burret. (1.56) and Miscanthus floridulus (Labill.) Warb. ex Schum. & Laut. (1.50).
