Road infrastructure expansion through jaguar habitat in South America is creating significant welfare and conservation impacts through vehicle collisions and habitat fragmentation.
Vehicle collision injuries in jaguars are among the most acute welfare events in large carnivore conservation. A jaguar struck by a vehicle and surviving the impact may experience severe trauma — fractured limbs, internal injuries, neurological damage — without access to veterinary care in remote road areas. Cub survival after maternal death in road collisions adds a secondary welfare crisis: dependent young without mothers face starvation unless rescued rapidly. The infrastructure decisions driving jaguar road mortality are made in planning processes that rarely account for wildlife welfare impacts. Incorporating wildlife mortality and welfare data into environmental impact assessments, and requiring wildlife crossing structures as a standard component of new roads through jaguar habitat, would reduce both welfare impacts and conservation costs.
