Can the UK's Toads Survive from Traffic and Terrible Decline?
It is a Friday evening at 7:30, but rather than heading to the pub or relaxing at home, I've taken a train to a town in the countryside to join local helpers from a amphibian rescue group. These dedicated individuals give up their evenings to protect the native amphibian community.
An Alarming Drop in Numbers
The common toad is growing more rare. A recent research led by an wildlife conservation group revealed that the UK toad population have almost halved since the mid-1980s. Seeing a creature that has been a stalwart of the UK landscape in decline is described as "worrying" by experts. Toads "don't require very particular environments" and "ought to live successfully in most of habitats in Britain," so if even they are struggling to persist, "it kind of suggests that the ecosystem is unbalanced."

The Threat from Roads
Though the research didn't cover the causes for the drop, traffic certainly plays a part. Estimates indicate that 20 tonnes of toads are killed on UK roads annually – that is, several hundred thousand. Unlike frogs, which would probably be happy to mate "with just a small container," toads favor large ponds. Their ability to stay out of water for more time than frogs allows they can journey farther to reach them – sometimes long distances. They tend to follow their traditional paths – it's common for adult toads to return to their natal pond to mate.
Migration Patterns
Appropriately enough, the first toads begin their quest for a partner around February 14th, but others travel as late as spring, waiting until it gets night and moving through the night. During that period, toads start moving from where they have been overwintering "all pretty much at the same time."
One volunteer, who was raised in the area and has been working to save its toad population since he was a child, explains that "They've got just one focus: to go and have an orgy." If their path crosses a street, they could be killed by traffic, and that breeding season would never happen – stopping a next generation of toads from being produced.
Toad Patrols Across the UK
Finding hundreds of dead toads on nearby streets "resonates deeply with people," and has led to the formation of toad patrols throughout the UK – hundreds of organizations are officially listed with a countrywide program. These teams pick up toads and transport them across roads in containers, as well as counting the number of toads they find and lobbying for other safety solutions, such as blocked roads and amphibian passages.
Volunteers usually work during the migration season, when toad crossings are frequent. However, this implies they can miss numbers of toadlets, which, having existed as eggs and then juveniles, leave their water habitats over an unpredictable schedule in late summer. Because of their small stature – just a couple of cm wide – "they can get obliterated by vehicles." And as being run over "basically turns them into mush," it's more difficult to collect information on them. At least when mature amphibians are killed, their carcasses can be counted.
Annual Efforts
In contrast to many groups, one local team, who are in their eighth year of functioning, go out year-round – not nightly, but when conditions are damp, or if a member has posted about a toad sighting in their messaging app. When I ask to join them on patrol, they concede it is "not a toady night" – toad hibernation season has started and it's been a arid period – but several of the helpers willingly accept to walk up and down their route with me and see what we can find. "If anyone can find any toads tonight, that pair will spot one," says the patrol manager, pointing to her teenage child and the longtime volunteer. We've been out for 120 minutes without a single toad sighting, and now they have scaled a wire barrier to inspect beneath some logs.
Community Participation
The family duo became part of the patrol a year and a half ago. The youngster adores all things wildlife and has an goal to become a conservationist, so his parent started to search for activities they could do jointly to help native animals. Now she loves it as much as he does, the 41-year-old entrepreneur tells me – so when the group was seeking a fresh coordinator recently, she volunteered for the role.
The youth, too, has been instrumental in the group. A video he created, imploring the municipal authority to close a road through a nature reserve during migration season, influenced the outcome the team's way. After a twelve months of campaigning, the council agreed to an "access-only" rule between evening and morning from February through to spring. The majority of motorists duly avoided the road.
Other Wildlife and Challenges
Several cars go past when I'm out on duty and we find some victims as a consequence – no amphibians, but several crushed salamanders. We see one living newt as well, and the teenager is particularly pleased to see a harvestman, which moves in his hands. Yet in spite of the group's hardest attempts to show me a toad, the native community has obviously gone dormant for the colder months. It seems that I couldn't have found any more luck anywhere else in the country – all the rescue teams I contact explain that it's near-impossible at this season.

One email I get from a different helper, who has kindly made the effort to look for toads in a noted location, considered the largest accurately monitored toad group in the UK, reaches me with the subject line: "None found." However, in February and March, he informs me, the group plans to assist around 10,000 adult toads across the road.
Impact and Limitations
What level of impact can these groups truly achieve? "The fact that people are doing this consistently on chilly, wet and miserable evenings is remarkable," says an researcher. "That's something that very much should be celebrated." However, while toad patrols are able to slow the decline, they cannot prevent it entirely – not least because traffic is not the only threat.
Additional Threats
The climate crisis has meant longer periods of drought, which create the wrong conditions for some of the creatures that toads eat, such as invertebrates, while warmer ponds have caused an rise of toxic plants, which can be toxic to toads. Warmer cold seasons also lead toads to wake up from their dormancy more frequently, disrupting the energy conservation crucial to their existence. Loss of environment – particularly the disappearance of large ponds – is another menace.
Researchers are "often concerned about overemphasizing practical benefits on wildlife," but "It's important in just having these animals around." But toads play an significant part in the ecosystem, consuming almost any invertebrates or small animals they can swallow and in turn sustaining a number of predators, such as hedgehogs and otters. Enhancing conditions for toads – such as building water habitats, protecting forests and constructing amphibian passages – "benefits for a wide range of other species."
Cultural Importance
Another reason to try to keep toads around is their "historical significance," notes an specialist. Myths and folklore around toads go back {centuries|hundred
