The mosaic landscape structure formed by conservation units in north coastal of Paraná

Abstract

The objective of this study was to analyze the landscape structure, matrix and patches, of the conservation units (CUs) that occur in the same area of Environmental Protection Area (EPA) of Guaraqueçaba to verify the mosaic functionality formed by these CUs. From the supervised classification of digital image Landsat-5 was defined the land cover classes and the area and perimeter attributes of polygons obtained. According to the landscape structure analysis, was observed that the CUs were communicated through native vegetation matrix interrupted by the presence of patches. The patches cover 21,40% of the studied area, which belong to classes of changed vegetation, exposed soil, urban areas, sad and water; mostly have less than one hectare and have a regular shape. The management categories of these areas match with the goals in each CU decree creating. The buffers zones of integral protection CUs are not fully incorporated within the limits of EPAs Federal and State of Guaraqueçaba. It concludes that, when taken together, each CU contributes to the local landscape conservation, promoting a functional mosaic of natural protected areas, according to the landscape structure and mosaic’s laws.
