No. of bitstreams: 1 AlanAR.pdf: 1676053 bytes, checksum: d3e0a1b377dfeb8291975976b8ac7146 (MD5) Previous issue date: 2009-03-02 / The aim of the present study was to identify the main plant use categories of native varieties from the Caatinga biome, in the rural community of Caic?, Rio Grande do Norte state (Northeastern Brazil). Semi-structured and structured interviews were used to gather information from local specialists about the use of the plants. The uses of 69 species are described by 23 observers (woodsmen, herb doctors, healers, farmers and housewives) aged 35 years or more. These species were allocated to seven categories: medicinal, wood plants, nutritional, mystic, fuel, forage plants and domestic use. The most represented families were Fabaceae (14 spp.), Euphorbiaceae (6 spp.), Cucurbitaceae (3 spp.) and Cactaceae (3 spp.). The calculation of use- value showed that the cumaru (Amburana cearensis (Allem?o) A. C. Sm) and the jurema-preta (Mimosa tenuiflora (Willd.) Poir) were the most commonly mentioned, in addition to having the largest number of uses. The data obtained confirm the potential of the plants from the Serid? region and reinforce the importance of biodiversity for rural communities, underscoring the need for local plant management / O presente estudo teve como objetivo identificar as principais categorias de uso de plantas nativas do bioma Caatinga, em uma comunidade rural no munic?pio de Caic?, Rio Grande do Norte (Nordeste do Brasil). Para isso, utilizaram-se entrevistas semiestruturadas e estruturadas buscando informa??es, junto a especialistas locais, sobre o uso das plantas. S?o descritos os usos de 69 esp?cies, reportadas por 23 informantes (mateiros, rezadeiras, raizeiros, agricultores e donas-de-casa) com idade superior a 35 anos. Estas esp?cies foram enquadradas em sete categorias de uso: medicinal, aliment?cia, madeireira, m?stica, combust?vel, forrageira e uso dom?stico. As fam?lias com maior representatividade na consulta foram Fabaceae (14 spp.), Euphorbiaceae (6 spp.), Cucurbitaceae (3 spp.) e Cactaceae (3 spp.). Atrav?s do c?lculo do valor de uso, observouse que o cumaru (Amburana cearensis (Allem?o) A. C. Sm.) e a jurema-preta (Mimosa tenuiflora (Willd.) Poir.) destacaram-se como as esp?cies com o maior n?mero de cita??es, sendo estas tamb?m as que obtiveram o maior n?mero de indica??es de usos. Os dados levantados comprovam o potencial de uso que possui a flora da regi?o do Serid? e tamb?m refor?am a import?ncia que a biodiversidade tem sobre as comunidades rurais, viabilizando o in?cio do manejo da vegeta??o local
