Resumo
In a landscape, it is important to consider its dynamic to understand the causes of habitat loss and the relationship of this landscape with other elements to propose priority areas for biodiversity conservation. In the present study, we considered the municipality of Rio Verde (GO) and analyzed its landscape in the years of 1987 and 2016. This municipality has an essentially agricultural economy and, therefore, its natural habitats had been converted in the anthropic landscape. We conducted the initial analysis interpreting the images of Landsat satellite for the years of 1987 and 2016, where we characterized: 1) increase in the agriculture areas; 2) reduction in the pasture areas; 3) reduction in the areas of savanna formation; 4) increase in the areas of forest formation; and 5) increase in the areas of Grassland formation. We observed that those areas of abandoned pasture or areas of savanna formation that were altered over the years were occupied by areas of Grassland formation. Based on landscape metrics obtained from Fragstats software, we observed that isolation was not altered among the analysed class, with the exception of urban areas and water. In 2016, the municipality of Rio Verde had only 198 fragments of native vegetation with more than 100 hectares, therefore, we suggest such fragments are the most priority to conserve the local biodiversity.
