Ethnobotanical study on wild edible plants used by three trans-boundary ethnic groups in Jiangcheng County, Pu’er, Southwest China

Traditional knowledge of wild edible plants, owned by Dai, Hani, and Yao people in Jiangcheng County, is rich but at risk of being lost among the young generation. Diversified cultivation of wild edible plants by the local communities could be a solution for the sustainable use of natural resources and to conserve the endangered species in this trans-boundary region.
