Diversity of plant uses in two Caicara communities from the Atlantic forest coast, Brazil

摘要

Caicara are native inhabitants of the Atlantic coast on southeastern Brazil, whose subsistence is based especially on agriculture and artisanal fishing. Because of their knowledge about the environment acquired through generations, Caicara people can play an important role in Atlantic Forest conservation. An ethnobotanical study was conducted within two Caicara communities (Ponta do Almada and Camburi beach, Sao Paulo State, Brazi), focusing on plant uses. In 102 interviews, 227 plant ethnospecieswere quoted, mainly for food, medicine, handicraft and construction of houses and canoes. People from studied communities depend on the native vegetation for more than a half of the species known and used. Using diversity indices, plant uses are comparedbetween studied communities and between gender and age categories within each community. We found quantitative differences in the knowledge about plants between gender categories for each kind of use (medicinal, food and handicrafts). Older and youngerinformants also have different knowledge about plants for handicraft and medicine, but not for edible plants.
