Common Toad: Dramatic Population Crash Needs Urgent Action

Common toad populations have crashed by 68 percent since 1985 making them one of the most rapidly declining British vertebrates.

Key Facts

UK common toad populations declined by 68 percent between 1985 and 2010
They migrate from overwintering sites to breeding ponds over short periods in early spring
Road mortality during migration kills hundreds of thousands each year
Common toads produce toxic bufadienolide secretions as a defence against predators
They are important predators of garden slugs and other invertebrates

Welfare Considerations

Common toads face welfare threats from road mortality during mass migration when hundreds are killed in short periods. Pond loss removes breeding sites. Agricultural drainage has eliminated many traditional ponds. Pesticide use reduces the invertebrate prey on which toads depend. Climate change is shifting migration timing leading to mismatches with volunteer toad patrol schedules.

What You Can Do

Volunteer with Toads on Roads patrol schemes during spring migration
Create garden ponds as breeding and resting habitat
Report local toad migration routes to Froglife for patrol coordination
Support pond restoration on farms and in green spaces
Advocate for toad tunnels and road management near major crossing sites
