A transition between the Cerrado and the Atlantic Forest creates a unique landscape, characterized by significant biological diversity, yet constantly threatened by human actions. Understanding the landscape structure focusing on forest fragmentation is crucial to provide support for biodiversity conservation, enabling society to sustainably utilize forest resources in the future. The aim of this study was to analyze forest fragmentation in an ecotone area between the Cerrado and the Atlantic Forest, considered a priority for environmental restoration in the state of Minas Gerais. Information available in MapBiomas 2022 served as the basis for creating the land use and land cover map of the region and the forest fragmentation map. Geoprocessing operations were conducted using ArcGIS, and landscape metrics, such as size and shape of each patch, were calculated using Fragstats. The landscape matrix is dominated by agricultural activities, and forest fragments have an average area of 5.74 hectares, with 82.16% being smaller than that. Fragments smaller than 1 hectare account for 32.57%. In the Atlantic Forest, there is a predominance of fragments smaller than 5 hectares, while in the Cerrado, 32.9% of forest cover is in fragments larger than 100 hectares. The values of the shape index did not differ significantly between biomes, except in the largest size class. It can be concluded that the landscape matrix characterized by agricultural activities has led to significant forest fragmentation in the region, with the Atlantic Forest area being more fragmented than the Cerrado area.
