Resumo
Ethnobotany is defined as the study of knowledge and concepts developed by any society about the plant world, covering either the way how the social group classifies plants, or their uses. Brazil, that is quite different, has about 40,982 species of flora and no less than 218 Indians, adding a population of approximately 350 thousand people. One of the aspects of ethnobotany is the survey of the species used by traditional communities. Such survey can serve as basis for the development of sustainable models once that natural environments such as the Brazilian Atlantic Forest, and their coastal environments, has been endangered for many years, and its original vegetation drastically diminished. Therefore, this study aimed to conduct the survey of the species known and used by communities from Pontal do Ipiranga and Degredo in order to generate data that contribute to the conservation of forest remnants and knowledge associated with them The study was done in Pontal do Ipiranga and Degredo, both localized in Linhares, ES. in area of sandbank that has been endangered by the human action. For the survey, were conducted excursions between March/2010 up to August/2010 with interviews, guided tours and collection of botanical material. The data obtained in the field were synthesized and were made qualitative and quantitative analysis, such as the value of use of species and the index of diversity. Three informers (two women in Pontal do Ipiranga and a man in Degredo) were identified by the method of Snowball. Besides, 57 people chosen randomly in both localizations, were interviewed. As the results were collected in a total of 85 species belonging 67 genus and 39 families for the both localizations. The families with the largest number of collected species were Fabaceae and Myrtaceae and the categories of use more representative were medicinal, alimentary, technology and ornamental. The ritualistic category only was registered in Pontal and honey varieties only in Degredo. The habit more often of the species in Pontal do Ipiranga was grass and in Degredo was bush and the most commonly used parts were fruits, flowers and stalk. The species with large value of use were AnacardiumoccidentaleL. and Eugenia unifloraL. with1,17 and 0,98 respectively. The diversity index of ethnobotany knowledge of the communities from Pontal do Ipiranga and Degredo was 1,67 in the base 10, considered low in relation to other studies. The main conclusions of the study are that the local informers, instead of in reduced number, can be recognized as specialist in the communities; the communities know little about of the native species more restricted; there are species, which not only useful to communities, are at risk of extinction and is critical to create a Conservation Unit in Pontal do Ipiranga and Degredo.
