| Summary: | The aim of this work was to map forest fragments in the Rio da Prata subwatershed, in Ibiraçu and Aracruz — ES, as well as to analyze the structure of the forest landscape by metric indexes and landscape ecology. Mapping was obtained by photo interpretation in a scale of 1:5,000. A hundred and sixty-four fragments were found, representing 40.69% of the Rio da Prata subwatershed total area. Very small fragments (<5 ha) were predominating in the subwatershed, totalizing 138 fragments. Therefore, the forest constitution in the subwatershed is mostly made up of fragments smaller than 5 ha, indicating an elevated degree of forest fragmentation. |
