The common toad is undergoing significant population decline in the UK, with road mortality during migration a key welfare and conservation issue.
Road mortality during toad migration causes death for large numbers of individual animals over a very short seasonal window. The welfare harm to toads struck by vehicles - which may survive injured in the road - is significant. Volunteer rescue programmes provide meaningful individual welfare relief while also contributing population-level conservation benefits. Structural solutions including permanent tunnels represent a longer-term welfare investment.
