Cultural keystone species of fauna as a method for assessing conservation priorities in a Protected Area of the Brazilian semiarid

The Cultural Keystone Species (CKS) method of identification has been used to define culturally important species. The objective of this study was to identify and characterize CKS vertebrates in the communities surrounding the Environmental Protection Area of Chapada do Araripe and define conservation priorities using semi-structured interviews and free listings. Interviews were conducted with 246 people; 53 species were identified and then included in categories of use: food, medicinal, handicraft and symbolic. Food preference was identified for Mazama gouazoubira, Penelope superciliaris, Dasyprocta prymnolopha and Dasypus novencimctus. As medicinal resources, Salvator merianae and M. gouazoubira represented 51.85% of treatment recommendations. For use in handicrafts, M. gouazoubira, which is also the only species recorded for symbolic use, stands out. Use values (UV) varied from 0.03 to 1.34, and M. gouazoubira had the highest UV (1.34) and a 0.74 projection. Regarding cultural importance, M. gouazoubira was the species with the highest UV and projection, and was indicated as a CKS to be prioritized in research and conservation studies.
