Medium and large sized mammals of the Boqueirão da Onça, North of Bahia State, Brazil

ABSTRACT The mosaic of protected areas of Boqueirão da Onça (8.636 km²), created in the north of Bahia state, is located in the Caatinga, an exclusively Brazilian biome, but exposed to a range of anthropic impacts that threaten its species and natural resources. Few data are available for various zoological groups in Caatinga, including mammals. In order to characterize the community of mammals of this region, considering species richness, we installed 80 camera-trap stations. With a sampling effort of 10,370 camera-days we recorded 28 species (22 wild and six domestic). Opportunistically, we recorded four mammals, resulting in a total richness of 32 species, five of which are included in the global list of endangered species, and seven in the national list. The results are significant, since the richness of wild mammals of the Boqueirão da Onça (S = 26) presented a high value when compared to other Caatinga localities. During the study we found evidence of human activities threatening the conservation of the region, such as poaching and deforestation. Therefore, there is an urgent need in the publication of the Management Plan of the recently created Boqueirão da Onça National Park, to minimize negative impacts on biodiversity and ensure the maintenance of ecological processes
