Optiflux: a tool for measuring wild animal population fluxes for the optimization of road infrastructures
In West European countries natural habitats are often fragmented. In those countries fragmentation is both characterized by an increase in the number of habitat fragments and a decrease in their size, leading to animal population isolation. The geometry of linear infrastructures (e.g., roads, railways) is not so much a cause of destruction of animal habitats, but rather it acts more as a barrier between fragments. If we consider linear infrastructure as a barrier in landscapes, it is important to study biological fluxes between landscape features before deciding the final route of such infrastructures. OptiFlux development is based on the “resistance concept,” developed by G. Pain for his Ph.D. (2001) for SCETAUROUTE.
