Urban Wildlife Corridors: Connecting Green Spaces for Animal Welfare

Urban wildlife corridors connect fragmented green spaces, allowing animals to move safely between habitat patches. Designing cities with corridors significantly improves urban wildlife welfare.

Key Facts

Urban areas cover approximately 3 percent of Earth's land surface but are growing rapidly
Green corridor networks in cities support higher wildlife diversity than isolated parks
Underpasses and overpasses specifically designed for wildlife reduce road mortality in urban areas
Private gardens collectively constitute significant habitat that can function as wildlife corridors when managed well
Urban heat islands create thermal stress for wildlife that shade corridors can partially mitigate

Welfare Considerations

Urban wildlife corridors address the fundamental welfare problem of habitat fragmentation in the built environment. Urban animals that cannot move safely between habitat patches are effectively trapped in small areas with limited resources, facing stress from high predation pressure, reduced food diversity, and inability to establish territories or find mates. Purpose-designed wildlife infrastructure — underpasses, green bridges, planted corridor strips — allows safe movement that reduces these welfare costs. Garden networks can function as informal corridors when managed with wildlife in mind: connecting hedgehog highways between gardens, planting pollinator strips that create movement routes for invertebrates, and reducing barriers to movement through boundary design all contribute to network function.

What You Can Do

Create hedgehog highways connecting your garden to neighbors through fence gaps
Advocate for wildlife corridor requirements in urban planning and development approvals
Support urban green infrastructure funding that prioritizes connectivity over isolation
Plant native species in gardens and verges that provide stepping stone habitat for wildlife movement
