          Abstract

          A Reserva Extrativista Marinha de Arraial do Cabo (RESEX) localiza-se no município de Arraial do Cabo, região de Cabo Frio. É uma unidade de conservação de interesse ecológico-social e visa proteger o sustento dos pescadores artesanais, a flora e a fauna locais. O clima da região é tropical seco e a vegetação é de restinga. Este estudo objetivou inventariar as espécies vegetais usadas na faixa terrestre da RESEX, associando este conhecimento às tradições locais. As informações etnobotânicas foram obtidas através de observação participante e entrevistas estruturadas com pescadores artesanais. Das 444 citações de uso, catalogou-se 68 espécies, 61 gêneros e 42 famílias. As categorias de uso foram: alimentar (45,6%), medicinal (39,7%), tecnológica (29,4%), lenha (10,2%), construção (8,8%) e ornamental (2,9%). Utilizou-se o Índice de Shannon para análise da diversidade de espécies resultando: 1,78 (base 10) e 4,10 (base e), denotando que os pescadores possuem bom conhecimento da biodiversidade local, quando comparado a outros estudos da costa brasileira. Os dados obtidos nesta pesquisa possibilitarão a formulação de estratégias de uso sustentável dos recursos naturais, considerando a percepção ambiental da população, baseado nos sistemas cognitivos desenvolvidos ao longo do convívio do homem com a natureza.

          The Arraial do Cabo Marine Extractive Reserve (RESEX), is located on Arraial do Cabo Municipality, Cabo Frio region. It is a conservation unit with social and ecological interest, that intends to protect the livelihood of traditional fishermen, local flora and fauna. The climate is tropical dry and the vegetation classified as sandy-coastal-plain vegetation. This study goal was to survey useful species on the land part of RESEX, and associate this knowledge to local traditions. The ethnobotanical data was obtained by observer participation and structured interviews with traditional fishermen. From the 444 use citations, there were 68 species, 61 genera and 42 families. Use categories were as follows: food (45,6%), medicinal (39,7%), technology (29,4%), firewood (10,2%), construction (8,8%) and ornamental (2,9%). The Shannon Index was used to analyse the diversity of useful species, with the result of 1,78 (base 10) and 4,10 (base e), showing that the local fishermen have knowledge about the biodiversity, compared to other studies of Brazilian coast. Data from this research will make possible the development of strategies for the sustainable use of natural resources, considering the environment perception of the population, based on cognitive systems developed over time between man and nature.
