The composition, structure and dynamics of the community of medium and large-sized terrestrial mammals of Parque Estadual da Serra do Brigadeiro (PESB), an Atlantic Forest fragment in southeastern Minas Gerais. In this study, three samplo blocks were selected for data collection from July 2007 to Agust 2008. The camera trap methodology was used for registering species. To evaluate vegetational dendrometric structure, the quadrant point methodology was used. Eleven species were registered, being one domestic and four in some threat category. All sample points in Vale Perdido registered at least one species of terrestrial mammal in four field trips. In Matipó block, the same collection effort resulted in at least one species registered in 62.50% of the sample points. In Ararica block, only 25% of sample points (N=2) were responsible for species registers. Community structure was based in geometric series with dominance of few species. In contraposition there was a relatively high proportion of species that would be expected to be rare for the observed structure, with prevalence of the puma (Puma concolor) over the others species of the community. Dendrometric structure data from each sample block presented little differences, indicating that blocks structure is similar, with exception for the median distance between trees and their highness (Matipó vs. Ararica). Our results show that the sample block named Vale Perdido is the most important for mammalian conservation in PESB, because it can presents in its conformation, structural and spatial characteristics that favour area usage by species. The structure of PESB medium and large-sized terrestrial mammals community is found destructurate or in structuration. Possibly, this model was occasionated by negative historical effects in the regional where PESB is located. Dendrometric characteristics were not sufficient to explain possible differences found among species richness in the north area of the park, since Matipó seems to be in a more advanced secondary successional sere. However, it was not the sample block with more species registers.
