Designing Wildlife Corridors for Safe Movement

Wildlife corridors connecting fragmented habitats allow animals to move safely between areas for foraging, breeding, and dispersal, improving both population viability and individual welfare.

Key Facts

Habitat fragmentation is the leading cause of wildlife population decline globally
Road mortality kills an estimated 1.3 million vertebrates per day in the US alone
Wildlife underpasses and overpasses can reduce road mortality by over 90% for targeted species
Corridors must be wide enough for target species to use them with confidence
Green roofs and urban gardens can form corridor stepping stones in cities

Welfare Considerations

Habitat fragmentation forces animals into dangerous situations that cause direct mortality and chronic stress. Animals attempting to cross roads, navigate suburban gardens, or traverse industrial land to reach food, mates, or seasonal ranges face risks that cause injury and death. Well-designed wildlife corridors reduce these risks by providing safe passage routes with appropriate cover and connectivity. The individual welfare benefit of a wildlife underpass is real: each animal that uses it safely instead of attempting a road crossing avoids a potentially fatal or injurious encounter.

What You Can Do

Advocate for wildlife crossing infrastructure on major roads in your region
Create garden corridors by collaborating with neighbours on hedge gaps and pond creation
Support green infrastructure requirements in local planning policy
Donate to organisations mapping and protecting wildlife movement routes
Volunteer for wildlife monitoring programmes that track corridor use
