Wildlife Corridors and Animal Welfare

Wildlife corridors connecting fragmented habitat patches reduce road mortality, enable genetic exchange, and allow seasonal migrations that are essential to wildlife welfare.

Key Facts

Habitat fragmentation from roads and development is one of the leading causes of wildlife population decline globally
Wildlife overpasses and underpasses in Banff National Park reduced wildlife-vehicle collisions by over 80%
Without corridors, isolated populations face inbreeding depression, reduced disease resistance, and local extinction
Migrating species including elk, deer, pronghorn, and wolves depend on corridors for seasonal range access
The Western Wildway project proposes a wildlife corridor from Mexico to Canada through the Rocky Mountains
Nature-based solutions including hedgerow networks and road underpasses can create corridors at landscape scale

Welfare Considerations

Wildlife trapped in habitat fragments face welfare harms that accumulate over time: road mortality risk for every movement, competition for limited resources in isolated patches, failed reproduction from inbreeding, and starvation when local food sources are depleted. Corridors restore the behavioral freedom animals evolved to use - migration, dispersal, and seasonal ranging. Each individual animal that can move safely through a corridor instead of across a road represents a welfare improvement alongside the conservation benefit.
