Rapid ethnobotanical diagnosis of the Fulni-6 Indigenous lands (NE Brazil): floristic survey and local conservation priorities for medicinal plants

摘要

This study was developed as part of the project "Studies for Environmental and Cultural Sustainability of the Fulni-6 Medical System: Office on handling medicinal plants". The Fulni-6 people are located in Pernambuco State, Northeastern Brazil. One of the components of this project was an ethnobotanical diagnosis of the indigenous land, where a phytosociological survey was performed in an area of Caatinga vegetation, located at Ouricuri settlement. Based on these ethnobotanical data, we calculated a conservation priority index aiming to rank species that should receive immediate attention from the Fulni-6 people. We identified 44 woody plants, 50% of which have a medicinal use. Among these, six plants were considered highly vulnerable and in need of immediate conservationist attention, in order to ensure the perpetuation of these species and the sustainability of traditional therapeutic practices of the Fulni-6: Anadenanthera colubrina, Myracrodruon urundeuva, Lippia sp., Spondias tuberosa, Maytenus rigida, and Siderox-ylon obtusifolium. We recommend the direct involvement of the Fulni-6 people in the conservation and the management of local resources by implementing a management plan and monitoring strategies for the populations of plants considered most important by the indigenous group.
