The Common Toad is one of the UK’s most widespread amphibians and a familiar species in gardens, woodlands and farmland. Adults typically measure 8–13cm in length, with females larger than males. They have dry, warty brown or olive skin, copper-coloured eyes with horizontal pupils, and distinctive parotoid glands behind the eyes which secrete a mild toxin to deter predators.
Common Toads spend most of the year on land, favouring damp habitats such as woodland, hedgerows, rough grassland, parks and gardens, where they feed on invertebrates including slugs, beetles and worms. In early spring, adults migrate – often returning to the same breeding site each year – to spawn in ponds or lakes. Unlike frogs, toads lay their eggs in long strings wrapped around submerged vegetation. After breeding, adults return to terrestrial habitats, while juveniles disperse into the wider landscape.
Although still relatively widespread, Common Toad populations have declined significantly in recent decades. Their reliance on both aquatic and terrestrial habitats makes them particularly vulnerable to habitat fragmentation and barriers within the landscape. In 2016 Froglife analysed its Toads on Roads dataset, this citizen science project operates with volunteers rescuing toads from road mortality in the spring months. Froglife’s research found a 68% decline in common toad populations across the UK including Scotland. Following this finding Froglife and many other conservation organisations put a heavy focus on toad conservation actions. In 2024 Froglife re-ran the research adding a further 8-years of data. This concluded that common toad population declines had dropped to 47%, this remains an alarming decline but is evidence that with concerted conservation efforts wildlife declines can be reversed.
Action Needed
Protect and restore ponds, ensuring they are well connected to suitable terrestrial habitat. Safeguard rough grassland, hedgerows, woodland edges and garden habitats. Reduce road mortality through toad patrols, temporary road closures or wildlife tunnels. Promote wildlife-friendly gardening and create new ponds to strengthen local populations. Support monitoring programmes to track trends and guide conservation action.
Threats
Habitat loss and fragmentation are major threats, particularly the loss of breeding ponds and surrounding terrestrial habitat. Toads are hereditary and will attempt to return to the same breeding pond, often having to cross roads and other transport infrastructure. Road mortality during spring migrations causes significant population declines. Urban development, agricultural intensification and drainage reduce habitat connectivity. Pollution and climate change – including drought affecting breeding sites – further impact populations.
