Large carnivores require vast territories that increasingly conflict with human land use, and wildlife corridors enable safe movement that reduces conflict deaths and welfare harm.
Large carnivores living in fragmented habitats face a sustained welfare and survival challenge. Individuals attempting to cross highways in search of mates or new territories are frequently killed or injured by vehicles. Those confined to isolated habitat patches may face reduced prey availability, inbreeding, and eventual local extinction. Wildlife crossings — bridges or underpasses designed for wildlife — are highly effective and relatively low-cost investments that allow carnivores to move safely between habitat areas. Each crossing prevents vehicle collisions that cause acute suffering and death, while maintaining genetic connectivity that supports long-term population viability. The welfare case for corridor investment mirrors the conservation case: both are served by enabling natural movement.
