Priority conservation of medicinal woody plants from protected forests based on ecological and ethnobotanical data.

The combination of ethnobotanical and ecological knowledge is an important tool in indicating priority species for conservation. We sought to gather ethnobotanical knowledge on the diversity and use of woody medicinal plants in the Chapada Araripe region, assessing the real availability of woody medicinal resources in the Araripe Forests in the cerrado and carrasco areas, and indicate priority species for conservation. A total of 107 species were recorded in the ethnobotanical surveys, classified into 39 families and 83 genera, of which 92 species, 36 families and 70 genera for the cerrado areas, and 47 species, 25 families and 39 genera, for the carrasco areas.
