Common toads face severe mortality during their annual migration to breeding ponds, with roads crossing traditional migration routes causing population declines across Britain.
Road mortality during toad migration represents acute, preventable suffering on a large scale. Individual toads hit by vehicles may not be killed instantly, experiencing significant distress before death. The scale of mortality is sufficient to cause measurable population declines at many sites, meaning road-crossing mortality is simultaneously a welfare and conservation crisis. Toad patrol volunteers provide direct welfare benefit by physically reducing mortality during migration nights, while longer-term solutions including toad tunnels and road closures during peak migration provide permanent infrastructure improvements.
