The Brazilian dwarf brocket deer (Mazama nana; Mammalia: Cervidae) is an elusive deer species that occupies the forests of southern Brazil, northern Argentina, and eastern Paraguay. A drastic reduction in forested areas has greatly affected the species, the least studied Neotropical deer. As do many threatened and elusive species, the Brazilian dwarf brocket deer needs a refinement of its distribution that would indicate proper sites to guide its conservation in situ. This project aimed to determine species distribution in order to establish priority areas for conservation. Given the rarity and elusiveness of the species, we proposed indirect methods to achieve this objective. We tracked and collected faecal samples in protected areas spread over southern Brazil with the help of a scat detection dog. Following species identification by PCR/RFLP and sample spatialisation, we modelled the species distribution using MaxEnt software. We found that the potential geographical distribution of the Brazilian dwarf brocket deer in Brazil is spread over the states of Parana, Santa Catarina, northern and central Rio Grande do Sul, the extreme south of SAo Paulo and Mato Grosso do Sul, eastern Paraguay, and the Misiones province in Argentina. The west and centre of Parana state and part of western Santa Catarina state were identified as high conservation priority areas.
