Welfare of Wild Animals in Ecological Corridor Programs

Wildlife corridors reconnect fragmented habitats but also expose animals to corridor-specific welfare risks including road crossings, conflict zones, and novel predation dynamics.

Key Facts

Wildlife corridor programs have restored connectivity for mountain lions, black bears, and wolves in North America
Animals moving through corridors encounter road traffic, agricultural land, and human settlements as hazards
Corridors that are too narrow lack the habitat quality needed to support animals long-term
Successful corridors include underpasses, overpasses, and habitat management along their full length
Corridor effectiveness monitoring tracks both animal movement and welfare outcomes for corridor users

Welfare Considerations

Wildlife corridors are a critical tool for addressing habitat fragmentation, but corridor design determines whether animals moving through them gain welfare benefit or encounter new hazards. A corridor that funnels animals through a high-traffic road creates a mortality trap. A well-designed corridor with safe crossing infrastructure, adequate habitat quality, and appropriate width enables genuine movement with manageable welfare risk. Monitoring corridor use and welfare outcomes — not just presence of movement — is essential for optimizing corridor design.

What You Can Do

Support wildlife corridor programs that include welfare monitoring alongside movement tracking
Advocate for wildlife crossing infrastructure in corridor design as a standard requirement
Donate to organizations building and monitoring wildlife corridor effectiveness
Engage with land use planning processes to maintain potential corridor connections
