The Serra do Brigadeiro State Park Minas Gerais covered its largest part for the Atlantic forest. Being known that the Atlantic forest is one of the main hotspots in the world, the recovery of this hotspot is a large challenge. The knowledge of the ecology of the species of mammals is of great importance in the biological dynamics of the rainforest, as the Atlantic forest, the understanding of this dynamics and the knowledge of the populations in forest fragments are important for elaboration of handling plans. The use of photographic traps for the knowledge of the ecology of the species of mammal medium and large sized, stands out for being a noninvasive, registers stealthy animals, animals that occur in low densities and allows monitoring of several points for long periods. The general objective of this work was to evaluate the diversity of mammals of medium and big load of terrestrial habits, through the camera trap along the Conservation Unit State Park of Serra do BrigadeiroMG. This study was led in the period of January from 2011 to August of 2012. The area of PESB was logistically subdivided in six areas that it accounted 59,175 Km2 in its totality, approximately 39,49% of the total area of the park. With this study it was possible to note 21 species of mammals, 15 were of wild mammal medium and large sized, two were small sized, three were domestic species, the man specie also was registered. The observed richness of wild mammals of medium and large size in this study represents 78.95% of terrestrial wild mammals of medium and large sized, that were already diagnosed in the park. The subarea 6 obtained the largest number of species of wild mammals of medium and big load registered (nine), following by the subareas 1 and 2 with eight species and the subareas 3, 4 and 5, was obtained seven, six five species registered respectively. The most abundant species for the PESB as a whole was the Cuniculus paca, followed by Puma concolor, Leopardus pardalis and the Pecari tajacu. The species P. concolor was the only species registered in all of the subareas, the species L. pardalis only was not registered in the subarea 6. Was estimated a richness to the PESB of 18 ± 1.73 species of wild mammals of medium and large. There is a great heterogeneity in the wealth and distribution in the wild mammal fauna of medium and large sized along the PESB. Through the interpretation of the data on the aspects of the diversity as the indexes of Jaccard Similarity, Shannon-Wiener Diversity and Pielou Evenness, was observed that there is an ecological heterogeneity in the mammal fauna of medium and big load along the PESB. Due to the found ecological heterogeneity, in environments in these conditions, it is verified that, a distribution of the effort of sampling in the sampling area is more effective than a great effort in a representative area, for a survey of mammal fauna of medium and large sized.The presence of humans and domestic mammalian species recorded throughout the study reveals the fragility of this unit conservation and is recommended surveillance improved by the management of the conservation area to prevent the free movement of people and animals within the UC.
