Will the UK's Common Toads Survive from Traffic and Population Collapse?

It's Friday night at 7:30, but instead of going out or watching a film, I've caught a train to a market town in Wiltshire to meet up with local helpers from a amphibian rescue group. These committed people give up their nights to safeguard the local toad population.

A Worrying Decline in Numbers

The common toad is growing more rare. A latest research led by an amphibian and reptile charity showed that the British common toad numbers have almost halved since 1985. Seeing a species that has been a fixture of the UK landscape in decline is labeled "concerning" by experts. Toads "don't require very specific conditions" and "should be able to live quite well in the majority of habitats in the UK," meaning if even they are struggling to persist, "it kind of suggests that the ecosystem is unbalanced."

The Danger from Traffic

Though the study didn't cover the causes for the drop, cars is a major factor. Estimates indicate that 20 tonnes of toads are killed on British roads annually – that is, hundreds of thousands. Unlike frogs, which might be content to mate "if you left out a bucket of water," toads prefer big bodies of water. Their ability to remain away from water for longer than frogs allows they can journey farther to find them – often hundreds of metres. They tend to follow their traditional paths – it's common for adult toads to go back to their natal pond to mate.

Migration Patterns

Fittingly, the first toads start their journey for a mate around Valentine's day, but some move as late as spring, waiting until it gets dark and moving through the night. During that period, toads begin migrating from wherever they have been overwintering "all pretty much at the same time."

One volunteer, who was raised in the area and has been trying to protect its toad population since he was a boy, explains that "Their sole purpose: to go and mate." If their route crosses a road, they could all get run over, and that mating period would never happen – stopping a new generation of toads from being produced.

Toad Patrols Across the United Kingdom

Seeing many of dead toads on nearby streets "inherently strikes a chord with people," and has resulted in the formation of rescue teams across the UK – 274 groups are currently registered with a countrywide program. These teams pick up toads and carry them across roads in containers, as well as recording the quantity of toads they encounter and lobbying for other protection measures, such as road closures and underground wildlife tunnels.

Patrols usually work during the migration season, when amphibian movements are frequent. However, this means they can miss groups of toadlets, which, having been spawn and then tadpoles, leave their ponds over an irregular timetable in the end of summer. Because of their small stature – just one or two centimetres wide – "they are destroyed by car traffic." And as being run over "essentially crushes them," it's more difficult to collect information on them. At least when adult toads are lost, their carcasses can be tallied.

Annual Efforts

Unlike most patrols, one local team, who are in their eighth year of operating, go out throughout the year – not every night, but whenever weather are warm and wet, or if someone has posted about a toad sighting in their messaging app. When I request to accompany them on duty, they admit it is "not a toady night" – toad hibernation season has begun and it's been a dry day – but a few of the volunteers willingly accept to walk up and down their route with me and search for any toads. "Should anyone can locate any toads tonight, those two will find one," says the patrol manager, indicating her teenage child and the experienced member. After for 120 minutes without a single toad sighting, and now they have climbed over a wire barrier to inspect beneath some wood.

Community Participation

The family duo joined the group a year and a half ago. The teenager loves all things nature-related and has an goal to become a environmentalist, so his parent started to search for activities they could do jointly to protect native animals. Now she loves it as much as he does, the middle-aged small business owner explains – so when the team was seeking a fresh coordinator lately, she volunteered for the role.

The teenager, too, has played an important role in the organization. A video he made, imploring the local council to block a road through a protected area during migration season, influenced the outcome the team's way. After a year of lobbying, the authority agreed to an "restricted access" restriction between evening and morning from late winter through to April. Most drivers duly avoided the road.

Additional Species and Challenges

A few cars go past when I'm out on duty and we find some victims as a consequence – no toads, but several crushed salamanders. We spot one living newt as well, and the teenager is especially excited to see a harvestman, which dances in his hands. Yet in spite of the team's best efforts to let me see a toad, the local population has obviously settled down for the winter. It seems that I couldn't have found any better success anywhere else in the country – all the patrol groups I reach out to clarify that it's near-impossible at this time of year.

A message I receive from another volunteer, who has generously taken the trouble to check for toads in a famous site, thought to be the biggest tracked toad group in the UK, reaches me with the subject line: "None found." However, in late winter, he tells me, the group plans to assist around ten thousand adult toads across the road.

Impact and Challenges

What level of impact can these organizations truly achieve? "The fact that people are doing this consistently on chilly, wet and miserable late nights is quite extraordinary," notes an researcher. "That's something that very much should be celebrated." However, while rescue teams are able to slow the decline, they cannot prevent it entirely – partly since vehicles is not the only threat.

Other Dangers

The climate crisis has meant longer periods of drought, which cause the poor environment for some of the animals that toads eat, such as worms and slugs, while warmer ponds have caused an increase of blue-green algae, which can be harmful to toads. Warmer cold seasons also lead toads to wake up from their dormancy more often, disrupting the resource preservation vital to their life cycle. Habitat destruction – especially the disappearance of big water bodies – is another menace.

Researchers are "often concerned about overemphasizing practical benefits on biodiversity," but "There is a big value in just having these animals around." But toads play an important role in the ecosystem, consuming almost any small creatures or small animals they can fit in their mouths and in turn sustaining a number of birds and mammals, such as hedgehogs and otters. Improving conditions for toads – ie creating more ponds, protecting forests and constructing toad tunnels – "we'll improve them for a whole bunch of other species."

Historical Significance

An additional motive to work to preserve toads around is their "important cultural value," notes an specialist. Legends and tales around toads date back {centuries|hundred
