Urban Wildlife Corridors and Connectivity

Urban wildlife corridors connect fragmented habitat patches, allowing animals to move safely between areas, maintaining population genetics and individual welfare in increasingly developed landscapes.

Key Facts

An estimated 65% of global land is fragmented by human development to some degree
Wildlife corridors reduce roadkill, inbreeding, and the genetic depression of isolated populations
Green roofs, garden networks, and stream corridors all function as urban wildlife habitat connections
The Yellowstone to Yukon initiative protects a 3,200 km corridor spanning national boundaries
Smaller-scale garden connectivity through hedgehog holes and bat boxes supports local urban wildlife

Welfare Considerations

Urban wildlife corridors benefit individual animal welfare by enabling the movements essential for feeding, breeding, and seasonal behavior. Animals trapped in isolated habitat patches face food shortages, inbreeding, and inability to disperse from deteriorating conditions. Simple connectivity measures at garden scale — hedgehog holes, bat boxes, wildlife-friendly fencing — aggregate into functional corridors at neighborhood and city scale. Urban corridor development is simultaneously a welfare and conservation intervention that residents can implement at home.

What You Can Do

Create a hedgehog hole in your garden fence to contribute to local connectivity
Plant native hedgerows and shrubs that serve as wildlife movement corridors
Engage with local planning authorities about incorporating wildlife corridors in development approvals
Support city and regional wildlife connectivity mapping and protection programs
Donate to organizations designing and implementing urban wildlife corridor initiatives
