Wildlife Corridor Design: Connecting Habitats for Animal Welfare

Wildlife corridors link fragmented habitats and allow animals to move safely between populations, improving survival and welfare.

Key Facts

Habitat fragmentation is the leading driver of wildlife population decline globally
Wildlife corridors — strips of connected habitat — enable safe movement between isolated patches
Road mortality is significantly reduced in areas with well-designed wildlife crossing structures
Corridors support genetic exchange, reducing inbreeding depression in small isolated populations
Effective corridors must be wide enough for target species to use confidently
Overpasses and underpasses have dramatically reduced mortality for large mammals in many regions

Welfare Considerations

Habitat fragmentation causes welfare harm at multiple levels: individual animals attempting to cross roads face injury and death; isolated populations suffer from reduced genetic diversity and inbreeding effects; and habitat patches too small to support natural home ranges confine animals to areas that cannot meet their behavioural and nutritional needs. Wildlife corridors restore connectivity, enabling animals to move between patches safely, find mates, access seasonal resources, and avoid human-dense areas. Welfare improvements from corridor restoration — reduced road mortality, genetic diversity maintenance, and access to larger effective home ranges — benefit both individual animals and population viability.
