Common toad populations have declined by 68% in the UK since the 1980s. Road mortality during spring migration is a significant welfare concern that community action can address.
Road mortality during toad migration causes traumatic deaths for individual toads attempting to return to their ancestral breeding ponds. Vehicles that strike toads at speed kill them instantly or leave them injured to die slowly at the roadside. Toad patrols that collect and carry toads across roads save individual animals from this fate and provide valuable population data. The evidence from sites where toad tunnels have been installed shows dramatic reduction in road mortality with rapid population recovery. Both interventions - toad patrols and permanent tunnels - address the same welfare problem: individual toad mortality during a brief, predictable seasonal event.
