Wild Animal Welfare

Wildlife Corridors and Mammal Welfare

How wildlife corridors reduce stress, injury, and mortality for mammals by enabling safe movement between habitat patches.

Key Facts

Habitat fragmentation forces mammals to cross roads, leading to millions of road deaths annually
Wildlife underpasses and overpasses reduce road mortality by 80-95% for target species
Isolation of populations increases inbreeding stress and reduces genetic diversity
Large mammals like mountain lions require ranges of hundreds of square miles
Corridors also reduce human-wildlife conflict by enabling natural movement patterns

Welfare Considerations

Wildlife corridors directly benefit mammal welfare by reducing road collision injuries and deaths, stress from habitat isolation, and population-level vulnerability to disease. For individual animals, safe movement between habitat patches means access to mates, food, and territory without the extreme stress of road crossing. Corridor design that considers species-specific movement patterns maximizes welfare benefits.

What You Can Do

Support local wildlife crossing projects through advocacy and donations
Slow down when driving through wildlife corridor areas
Plant native vegetation to connect backyard habitats to larger green corridors
Vote for ballot measures that fund wildlife crossing infrastructure
