Wildlife Corridors and Animal Welfare

Wildlife corridors connect fragmented habitats, reducing animal stress and mortality from isolation, inbreeding and attempted crossings of dangerous human infrastructure.

Key Facts

Habitat fragmentation forces animals to attempt road crossings, causing 1.3 million vertebrate deaths daily in the US alone
Wildlife bridges (ecoducts) in the Netherlands have reduced road mortality by up to 60% for target species
Isolated small populations show increased inbreeding and reduced disease resistance within 5 generations
Corridor connectivity allows range shifts in response to climate change, reducing climate-driven welfare harms
Rewilding projects with corridors show increased predator-prey balance and reduced prey stress from ambush risk

Welfare Considerations

Wildlife corridors address a pervasive but often invisible cause of animal suffering: habitat fragmentation. Animals in isolated patches experience the welfare harms of inbreeding, resource competition and stress from being unable to follow natural movement patterns. Those that attempt to cross roads or other barriers face high mortality. Corridors improve welfare at the population level by enabling animals to live out natural behavioral repertoires — migrating, finding mates, accessing seasonal resources — rather than being trapped in degraded fragments.

What You Can Do

Support land trusts and conservation organizations acquiring corridor land
Advocate for wildlife crossing infrastructure on major roads through wildlife habitat
Reduce garden barriers by creating hedgehog-friendly gaps in fences
Support planning policies that require wildlife corridor preservation in development projects
