13. Availability and use of woody plants in a agrarian reform settlement in the cerrado of the state of Goiás, Brazil
Protected areas are important sources providing plant resources for human populations, and contributing to the livelihood and income of families. To test the ecological apparency hypothesis, that there is positive relationship between the visibility of a species and its use, we conducted an ethnobotanical survey in the protected area of the Itaúna rural set
