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. 59% were present in the phytosociological surveys for cerrado and 38% for carrascos. Species with high versatility of medicinal use did not necessarily have high local availability, and some were not recorded in the sampling. Thirteen species in cerrados and four in carrascos were indicated as conservation priorities. Use not aligned of species with the reality of the present time can indeed affect the vegetation landscape, and in a future scenario, not taking local measures to conserve protected forest resources, besides increasing the lists of local conservation priorities, can affect economic practices, increasing social and environmental conflicts.
