SILVA, T.S.  e  FREIRE, E.M.X.. Ethnobotanical approach to medicinal plants mentioned by people from the environs of a caatinga conservation unit in Rio Grande do Norte, Brazil. Rev. bras. plantas med. [online]. 2010, vol.12, n.4, pp.427-435. ISSN 1516-0572.  http://dx.doi.org/10.1590/S1516-05722010000400005.

Caatinga, the only exclusively Brazilian biome, has suffered exploitation of its natural resources, with loss of biodiversity associated with wood and plant extract supply. The resulting impacts on this biome have led to the search for strategies for its conservation like the establishment of Conservation Units (CUs), such as the Ecological Station of Seridó (ESEC Seridó) located in Rio Grande do Norte State. The human communities in ESEC Seridó environs maintain a strong relationship with this conservation unit. Considering that the misuse of caatinga resources has been strongly linked to the needs of its inhabitants, this work aimed to investigate the environmental perception of communities from the environs of ESEC Seridó, focusing on the popular knowledge about plants of medicinal use. This investigation recorded 48 native and 39 exotic species, of which 31 and 14 species, respectively, had medicinal properties. The communities surveyed showed a deep knowledge of the plants found in that region and the wealth of these results is relevant for future management strategies in this Conservation Unit.

Palavras-chave : environmental perception; ethno-knowledge; native plants; exotic plants.
