Ethnopharmacological study of native medicinal plants and the impact of pastoralism on their loss in arid to semiarid ecosystems of southeastern Iran.

摘要: The purpose of this study was to gather ethnopharmacological information on plants used by the pastorals southeastern Iran. relationships between ecological value plant species and ethnobotanical indices were investigated. loss medicinal its effective factors also determined under nomadism sedentary pastoralism. Ethnopharmacological collected through interviews with 85 local people including nomads (43%) (57%). Ethnobotanical relative frequency citation (RFC), importance (RI), cultural (CV), use (UV) estimated. Canopy cover density measured at 60 sampling plots in exclosure, nomadic rangelands rangelands. Importance Value Index (IVI) Relative Loss (RL) estimated for both pastoral Pearson correlation coefficient investigate relationship IVI species. Bayesian networks loss. In total, 156 50 families identified region locals. Positive observed (RFC RI) index (IVI). mean decline approximately three times higher than showed that value, seed exploitation aerial parts had direct Bunium persicum, an ecologically socially important species, been extensively harvested (more 60%) rangelands, making it a priority future conservation programs. Medicinal high severely exploited, threatening sustainability arid semiarid ecosystems. Local not only as herbal remedies but consider them source income. Popular multiple uses more susceptible Higher knowledge did help mitigate loss, requesting new plans aware circumstances often leads removal from community. Given importance, abundance widespread plants, further studies can provide basis their identifying therapeutic effects region.
