Abstract The investigation of land use changes by anthropic processes, spatially and temporally, is a fundamental tool to establish correlations between landscape patterns and processes and management of the buffer zone of Conservation Units. This study aimed to analyze the forest fragmentation and land use dynamics in the buffer zone of the Rio Doce State Park (PERD), located in Minas Gerais, Brazil, for the year 2015. Its buffer zone was delimited to a radius of 10 km, covering a total area of 128.893,36 ha. Land use classification was based on Landsat 8 image, orbit 217, point 73 and 74, and two types of ecosystems were identified: natural and anthropic. In the thematic mapping, the pressure of the anthropic use over the natural was notified, as well as the high number of forest fragments, which is a negative impact on the resilience required for the conservation of biodiversity and the local Atlantic forest. The fragments have different shapes and sizes and are distributed through‑ out the buffer zone of the PERD. There is a need to adopt conservation strategies, such as environmental education, reforestation techniques, recovery of degraded areas and eco‑ logical corridors. Even with a worrying current scenario, this finding makes it possible to establish an optimistic point for biodiversity conservation, associated with a tendency to reduce the forces of direct changes on natural systems.

1 Introduction Habitats fragmentation has steadily increased in Brazil directly affecting the provision of multiple ecosystem services and associated biodiversity loss (Tabarelli and Gascon 2005). Atlantic Forest in Brazil is one of the most fragmented tropical forests in the world (Metzger 2009) holding 84% of its remaining area with isolated forest patches up to 50 ha (Ribeiro et al. 2009). However, several studies have been reporting a recent trend of forest transition. Between 2016 and 2017, total deforestation in the Atlantic Forest (across 17 Brazilian states) hit is minimum value of 12.562 ha. This is the lowest value since the monitoring carried out
