Ecological networks as a new approach for nature conservation in Turkey: A case study of Izmir Province

This paper aims to identify and evaluate a potential ecological network including core areas and large-scale corridors in the ¿zmir Province and its surrounding areas, Turkey. It is one of the first studies on the connectivity for mammal species and the detection of potential ecological corridors for Turkey. Four wide-ranging species (Hyaena hyaena, Lynx lynx, Caracal caracal, and Felis chaus) have been chosen as target species. Existing Key Biodiversity Areas (KBAs) and surrounding lands have been evaluated based on a three criteria: (1) vegetation/habitat types, (2) carrying capacity and (3) road density using simple GIS-based models. The results are evaluated using the Minimum Viable Metapopulation (MVMP) standards. No KBA in the study region has a Key Population (KP) or Minimum Viable Population (MVP) with the exception of Boz Da¿lar. Least cost-path analysis has been applied to identify linkages between KBAs relevant for the four target species. The conclusion is that it is possible to maintain MVPs in the region when the KBAs are linked by ecological corridors
