The ethnobotanical survey was made among the Thai, Muong, and Kinh tribes in the Nam Dong Commune, Quan Hoa District, Thanh Hoa Province of northern Vietnam. The investigation mainly focused on the plants used for various non-medicinal purposes (like basket and rope making, construction, traditional decorations, the fish poison, food, and forage) through structured questionnaires and consultations with knowledgeable ethnic elders. Totally 62 plant species were identified as economically important plants in the traditional ethnic lifestyle in the area. The present study accentuates the significant role of ethnobotanical researches, which needs to be documented by the extraction of traditional knowledge pertaining to the use of plants by future generations.
