Urban Wildlife Corridors: Connecting Fragmented Habitats

Creating connected habitat corridors through urban areas reduces the welfare impacts of habitat fragmentation on wildlife populations.

Key Facts

Urban areas cover around 10% of England but support significant wildlife populations
Habitat fragmentation isolates populations and reduces genetic diversity and resilience
Urban green corridors including parks, gardens, and road verges provide movement routes for many species
The wildlife-friendly garden movement has engaged millions of UK householders in habitat creation
Road crossing structures including badger tunnels and otter holts have significantly reduced road mortality

Welfare Considerations

Individual animals in fragmented urban habitats suffer welfare consequences including increased road mortality when attempting to move between patches, malnutrition in isolated territories with insufficient food resources, and reproductive failure from inability to find mates. Connecting fragmented habitats through corridor creation reduces these welfare impacts by enabling safer movement, gene flow, and access to seasonally variable resources. Even small garden modifications including log piles, native plantings, and pond creation can provide stepping stone habitat for invertebrates, birds, and small mammals. The cumulative welfare benefit of coordinated urban habitat creation across many gardens and public spaces is substantial.

What You Can Do

Create a wildlife-friendly garden with native plants, a pond, and shelter features
Join local wildlife corridor projects coordinated by your local wildlife trust
Advocate for wildlife-friendly design in urban planning and green infrastructure
Install hedgehog highways and log piles to connect your garden to neighbouring habitats
Report wildlife road casualties and advocate for road mitigation measures in your area
