The number of publications about the Caiçaras population is growing, which shows that researchers are interested in these natives. This study aimed to survey the flora used by local specialists of the Praia do Sono Caiçara community, and recorded how these taxa were used, with the goal of understanding traditional management systems that help to conserve natural ecosystems. Twelve informants were selected and interviewed. The applied grouping analysis, together with the chi-squared test, underlined that the analysed ethnobotanical knowledge showed a heterogeneous distribution in relation to the gender of the interviewee. A total of 190 taxa were cited and were classified into nine usage categories. The Shannon-Wiener index (H') value obtained in this study was the second highest in comparison to other Brazilian coastal communities. This work showed that the local specialists of this Caiçara community maintain a wide knowledge of, and affinity to, the plant resources that surround them. This knowledge is not only important, but fundamental to discussions about the application of sustainable use and management strategies for this area of conservation value.
