Wildlife Corridors and Animal Migration Welfare

Wildlife corridors allow animals to move safely between habitat patches — improving welfare and survival.

Key Facts

Over 1 million animals are killed on US roads every day
Wildlife crossing structures reduce road mortality by up to 95%
Mountain lions in fragmented California habitat show high rates of inbreeding
I-80 wildlife crossings in Nevada have documented use by dozens of species

Welfare Considerations

Wildlife corridors address one of the most pervasive sources of animal suffering in modern landscapes — habitat fragmentation. Road mortality kills millions of animals daily, from deer and coyotes to salamanders and turtles. Fragmented populations suffer from isolation, inbreeding, and difficulty accessing food and mates. Wildlife crossings — underpasses, bridges, and culverts — allow animals to move safely between habitat patches. Communities near wildlife crossing projects report significant reductions in vehicle-animal collisions with associated human safety benefits.
