Will the UK's Toads Survive from Roads and Terrible Decline?
It is Friday evening at 7:30, but instead of heading to the pub or relaxing at home, I've caught a train to a town in Wiltshire to meet up with local helpers from a toad patrol. These committed people sacrifice their nights to protect the native amphibian community.
An Alarming Decline in Population
The Bufo bufo is becoming increasingly uncommon. A recent study led by an amphibian and reptile charity showed that the UK toad population have almost halved since 1985. Observing a creature that has been a fixture of the British countryside in decrease is described as "concerning" by experts. Toads "don't need very specific conditions" and "should be able to live quite well in the majority of habitats in Britain," so if even they are struggling to persist, "it indicates that things are not as they should be."

The Danger from Traffic
Though the study didn't examine the reasons for the decline, traffic certainly plays a part. Estimates suggest that 20 tonnes of toads are crushed on UK roads annually – that is, several hundred thousand. In contrast to frogs, which would probably be content to mate "with just a bucket of water," toads favor big bodies of water. Their capacity to stay out of water for more time than frogs means they can journey farther to find them – sometimes long distances. They tend to stick to their traditional paths – it's common for mature amphibians to go back to their natal pond to mate.
Breeding Habits
Fittingly, the first toads start their journey for a partner around February 14th, but some move as late as April, until it gets dark and travelling after sunset. During that time, toads begin migrating from where they have been overwintering "almost simultaneously."
One volunteer, who was raised in the area and has been working to save its amphibians since he was a boy, explains that "Their sole purpose: to go and have an orgy." If their path happens to a road, they could be killed by traffic, and that breeding season would be lost – preventing a new generation of toads from being born.
Toad Patrols Throughout the United Kingdom
Seeing hundreds of dead toads on local roads "resonates deeply with people," and has led to the creation of toad patrols across the UK – 274 groups are currently registered with a national initiative. These groups collect toads and carry them across roads in containers, as well as counting the quantity of toads they encounter and lobbying for other safety solutions, such as blocked roads and amphibian passages.
Patrols tend to operate during the breeding period, when amphibian movements are frequent. However, this implies they can miss groups of toadlets, which, having existed as spawn and then juveniles, exit their ponds over an irregular timetable in the end of summer. Because of their size – just one or two centimetres wide – "they are destroyed by vehicles." And as being run over "essentially crushes them," it's harder to get data on them. At least when mature amphibians are lost, their remains can be tallied.
Annual Efforts
In contrast to most patrols, a specific volunteer group, who are in their eighth season of functioning, go out throughout the year – not nightly, but when weather are damp, or if someone has reported about a toad sighting in their messaging app. When I request to accompany them on patrol, they concede it is "not a toady night" – toad hibernation season has begun and it's been a dry day – but several of the volunteers gamely agree to patrol their route with me and see what we can find. "If anyone can find any toads tonight, those two will find one," says the patrol manager, indicating her 14-year-old son and the longtime volunteer. We've been out for two hours without a glimpse of any amphibians, and now they have scaled a barbed wire fence to check under some logs.
Family Involvement
The mother and son became part of the group a year and a half ago. The youngster adores all things wildlife and has an goal to become a environmentalist, so his parent started to search for things 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 decided to step up.
The teenager, too, has been instrumental in the organization. A video he made, imploring the local council to block a street through a nature reserve during breeding time, swung the decision the team's way. After a year of lobbying, the council agreed to an "restricted access" rule between evening and morning from late winter through to spring. Most drivers respected and avoided the route.
Additional Species and Difficulties
Several cars go past when I'm out on duty and we find some victims as a consequence – no amphibians, but three squashed newts. We see one live amphibian as well, and the youngster is especially excited to see a daddy longlegs, which dances in his hands. Yet in spite of the team's hardest attempts to show me a toad, the native community has clearly gone dormant for the colder months. It seems that I wouldn't have had any more luck anywhere else in the country – all the rescue teams I reach out to clarify that it's very difficult at this season.

A message I get from a different helper, who has generously taken the trouble to look for toads in a famous site, considered the biggest tracked toad population in the UK, arrives in my inbox with the subject line: "None found." However, in February and March, he tells me, the team plans to assist around ten thousand adult toads across the road.
Impact and Limitations
How much of a difference can these organizations truly achieve? "The reality that volunteers are doing this consistently on cold, damp and unpleasant late nights is remarkable," says an expert. "This effort that very much deserves recognition." However, while toad patrols are able to reduce the drop, they cannot prevent it entirely – partly since traffic is not the only threat.
Additional Threats
The global warming has resulted in extended spells of drought, which create the poor environment for some of the creatures that toads consume, such as invertebrates, while warmer ponds have caused an rise of toxic plants, which can be harmful to toads. Warmer cold seasons also cause toads to wake up from their hibernation more often, interfering with the energy conservation crucial to their existence. Habitat destruction – particularly the disappearance of big water bodies – is another menace.
Researchers are "always a bit worried about overemphasizing practical benefits on biodiversity," however "There is a big value in just their presence." But toads do have an important role in the ecosystem, consuming pretty much any invertebrates or small animals they can fit in their mouths and in turn feeding a number of birds and mammals, such as hedgehogs and otters. Improving situations for toads – such as creating more ponds, conserving woodland and installing toad tunnels – "we'll improve them for a whole bunch of additional wildlife."
Historical Importance
Another reason to try to keep toads around is their "historical significance," notes an expert. Myths and folklore around toads date back {centuries|hundred
