Abstract

The aim of the research was to verify plant genetic resources for medicinal purposes in transition areas in the State of Maranhão, Brazil. It was held in the municipalities of Morros, Cachoeira Grande and Rosario, located in the transition area Amazon?Cerrado, in Northeast Brazil. The study aims to analyze the risk of plant genetic resources used by local populations for medicinal purposes. Semi? structured interviews, informal conversations and free listings were applied for obtain the data, which encompassed the use and management of natural resources, economic activities and subsistence. Were 126 species cited, divided into 47 families. Highlights included four native woody species with greater importance and greater diversity of use: frangipani (Himatanthus sp.), aroeira (Astronium sp.), mapa (Parahancornia sp.), jatoba (Hymenaea sp.) The municipality of Rosario presented more cited species and the greatest number of exclusive species. In the three municipalities were cited 20 species. When analyzed Risk of Use (RU) for these species, it was observed that Himatanthus sp. RU showed high in all three municipalities; Parahancornia sp. RU presented high in Rosario and Cachoeira Grande, andAstronium sp. only in Rosario; Hymenaea sp., despite not having reached high risk values are in thelist of Brazilian flora plants at risk of extinction. The research cited species deserve more attention andstudies about use and management in order to avoid their vulnerability in their natural environments.
