The protection of medicinal plants has been effective as a key factor in preserving the environment of medicinal plants. As such, this paper aims to map the environment of medicinal plants based on biodiversity and indigenous knowledge, in which its role is constantly seen in environmental studies. The study method was based on field survey in the target areas: Morvarid, Heiderabad, Dehmoord, Fath al-Mubin in Darab city in Fars province. Based on the findings of the study, a total of 89 species belonging to 43 families in the target areas were identified, with the highest frequency belonging to the Mint family. According to the results of studies, Anghozeh, Baneh, Thyme Shirazi, Arjan, Kenar, Jashir (Prangos), Lemon balm, Myrtus, cumins, and Kakuti in need of protective measures. Combining indigenous plant ethnological knowledge with new technologies along with high genetic diversity will be the way to control damage and protect the effective genes of medicinal plants. Ultimately, the elimination of the inheritance of desirable plant genes will lead to the erosive growth and acceleration of the regression of plant cover, which is considered as a rich chain and preserver of soil sanctity and stability of nature in the environment.
