Wild Common Toad Road Ecology

Road ecology research has quantified the welfare cost of toad road mortality and identified optimal mitigation strategies.

Key Facts

Common toad road mortality during spring migration has been quantified at thousands of deaths per crossing per year at major hotspots
Toad tunnels reduce crossing mortality by over 95 percent at monitored sites
Optimal tunnel dimensions of 15 cm diameter and maximum 30 m length maximize toad use
Toad tunnel programs require drift fencing to guide toads to tunnel entrances
Mapping and prioritizing crossings by mortality rate allows efficient allocation of conservation resources

Welfare Considerations

Toads struck by vehicles suffer acute traumatic injury. Tunnel programs not only save individual lives but reduce the scale of suffering experienced by thousands of animals at mortality hotspots.

What You Can Do

Support Toad Patrol volunteer groups at key crossing sites during March migration
Advocate for toad tunnel funding from highway authorities as standard road safety infrastructure
Donate to mapping programs identifying and prioritizing toad crossing hotspots for tunnel installation
