Wildlife Corridor Effectiveness Evidence

Research increasingly validates the effectiveness of wildlife corridors in maintaining genetic connectivity and reducing mortality from fragmentation.

Key Facts

Corridors increase population viability by connecting isolated fragments
Camera traps confirm diverse species use designed corridors
Crossing structures reduce road mortality for large mammals significantly
Poorly placed corridors may increase predation if predators also use them

Welfare Considerations

Corridors reduce the welfare cost of fragmentation by enabling safer movement for individual animals. Animals forced to cross roads or open ground experience heightened stress, injury risk, and energy expenditure. Well-designed corridors reduce these individual-level welfare costs across entire populations.

What You Can Do

Support land trusts acquiring corridor properties between protected areas
Advocate for wildlife crossing infrastructure in road planning processes
Donate to organizations mapping and prioritizing critical corridor gaps
Engage with local planning processes to protect corridor lands from development
