| Sumario: | The methodology is focused on the use of digital air photos to monitor changes in land covers and to study its dynamics and its patterns in the last 50 years. The dissertation also take into account the relationship between open habitats patterns/dynamics versus biodiversity persistence, increase risk of fire, land ownership and management. Therefore Geographic Information System (GIS) is a very interesting mapping tool that enables geographic or spatial data capture, storage, retrieval, manipulation, analysis and modeling. Finally this research develop a heuristic model to create sites using suitability maps and a reserve design model to select the most optimum sites in order to increase landscape heterogeneity at the less cost. |
