Toad and Frog Road Mortality During Migration

Amphibian spring migration crossing roads results in mass mortality events that deplete local breeding populations.

Key Facts

Common toads may lose 30 to 50% of migrating individuals to road mortality in a single season
Mass road crossings occur at predictable times and locations determined by temperature and rainfall
Volunteer toad patrol programs using buckets to carry migrating toads across roads have been operating for decades
Amphibian tunnels under roads with drift fencing provide permanent solutions in high-mortality crossing zones
Amphibian populations have declined by 40% globally, with road mortality a contributing factor in fragmented landscapes

Welfare Considerations

Toads struck by vehicles experience acute trauma. Mass road mortality events during spring migration can functionally eliminate breeding populations from local ponds. The welfare harm is both acute and population-level. Toad patrols and tunnel installations are among the simplest and most cost-effective wildlife welfare interventions available.

What You Can Do

Volunteer with local toad patrol groups during spring migration season (typically February to April)
Advocate for local councils to install amphibian tunnels at known high-mortality road crossing sites
Drive slowly at night in rural areas near ponds and wetlands during mild, wet spring evenings
