Wildlife Corridors and Animal Welfare

Wildlife corridors enable animal movement between fragmented habitats, reducing road mortality, inbreeding, and welfare harms of habitat isolation.

Key Facts

Habitat fragmentation is one of the leading threats to wildlife populations globally
Corridors allow safe movement between habitat patches for feeding, mating, and seasonal migration
Road mortality kills an estimated 1 million vertebrates per hour on US roads alone
Wildlife underpasses and overpasses reduce road mortality by 70-90% where properly implemented
Florida panthers, grizzly bears, and wolverines are among species whose range recovery depends on corridors
Urban wildlife corridors support fox, deer, raccoon, and bird populations through cities

Welfare Considerations

Habitat isolation causes welfare harm through food insecurity when populations cannot reach seasonal resources, stress from inability to avoid competitors, inbreeding causing health problems, and the acute suffering of road casualties. Corridors address these welfare harms while also serving conservation goals - the welfare and conservation cases are strongly aligned. Road mortality in particular represents direct individual welfare harm at enormous scale, making road mitigation a high-impact intervention.

What You Can Do

Support land trusts and conservation organizations purchasing corridor land
Advocate for wildlife crossing infrastructure in road projects through public comment
Drive cautiously at dawn and dusk when wildlife is most active near roads
Install wildlife-friendly fencing on your property that allows passage of small animals
Plant native vegetation to extend habitat connectivity through suburban and urban areas
Support planning regulations that require wildlife corridor assessments for new development
