摘要: Defragmentation, i.e. the systematic action of reconnecting even smaller and more isolated landscape patches, is a major concern for analysists planners. Landscape fragmentation (LF) can jeopardize both ecosystem continuity quality. Transport mobility infrastructures (TMIs) are considered one main causes LF trigger negative effects, such as death wild animals killed by vehicular traffic, decrease connectivity. The effectiveness defragmentation actions be monitored through indices, Infrastructural Fragmentation Index (IFI) and, counterpart, connectivity index (CI). In this paper, we aim at illustrating effect based on use wildlife crossing structures (WCSs). WCSs targeted boar ideally located different linear densities in fragmented car accidents very rich unit Alghero, Sardinia, Italy. Results demonstrate that higher WCSs’ density average cost increases scenarios with denser WCSs.
