摘要
Biodiversity corridors are important environmental structures with the purpose of conserving and restoring biodiversity. This is mainly applied in areas degraded by uncontrolled human development that favors forest fragmentation and loss of connectivity between different habitats. Making use of remote sensing and geographic information systems, we sought to identify areas to act as biodiversity corridors, allowing gene flow between remnant fragments and areas of permanent preservation. For such purpose, a spatial analysis of the remaining fragments on Sao Gabriel do Oeste, Mato Grosso do Sul, was made, by its form, size and location. The areas for the corridors were identified from the location of fragments with potential, i.e., with proper size and conservation, besides considering the chart of land classes for mechanization and the map of priority areas for conservation from Ministry of Environment [Ministerio do Meio Ambiente], allowing the choice of better areas for biodiversity corridors. It was verified, that geotechnologies are important tools in helping to determine suitable areas for the integrated analysis of the landscape, as in helping on the delimitation of suitable areas for implanting corridors, generating an alternative scenario for environmental recovery, ecological zoning and environmental conservation.
