Large carnivores require vast territories and safe passage between habitat fragments. Wildlife corridor design that enables carnivore movement reduces conflict mortality, inbreeding, and the welfare costs of habitat fragmentation.
Wildlife corridors serve both conservation and welfare functions. Isolated carnivore populations experience inbreeding-related immune deficiencies, developmental abnormalities, and reduced fertility — all welfare harms compounded over generations. Individual animals attempting to cross roads or navigate fragmented landscapes face collision risk and territory disputes with established residents. Corridors reduce these welfare costs by enabling natural dispersal, genetic exchange, and territory establishment without forced confrontation. The welfare benefit to individual animals — reduced road mortality, reduced territorial conflict, reduced inbreeding — complements the population-level conservation benefit.
