Can Britain's Toads Survive from Roads and Terrible Decline?
It's a Friday evening at 7:30, but rather than going out or watching a film, I've caught a train to a market town in the countryside to join local helpers from a toad patrol. These dedicated individuals give up their evenings to protect the local toad population.
A Worrying Decline in Numbers
The Bufo bufo is becoming increasingly uncommon. A latest research led by an wildlife conservation group showed that the UK toad population have almost halved since the mid-1980s. Seeing a creature that has been a fixture of the British countryside in decrease is described as "worrying" by experts. Toads "don't need very particular environments" and "ought to live successfully in the majority of areas in the UK," meaning if even they are not managing to survive, "it kind of suggests that things are not as they should be."

The Threat from Roads
Though the study didn't examine the reasons for the drop, cars certainly plays a part. Estimates suggest that 20 tons of toads are killed on British roads annually – that is, several hundred thousand. Unlike frogs, which might be happy to mate "with just a bucket of water," toads favor big bodies of water. Their capacity to remain away from water for longer than frogs means they can travel further to reach them – often hundreds of metres. They tend to follow their ancestral migration routes – it's common for adult toads to return to their birth pond to mate.
Migration Habits
Fittingly, the initial amphibians begin their quest for a partner around Valentine's day, but some move as far as spring, waiting until it gets dark and moving after sunset. During that time, toads start moving from where they have been overwintering "almost simultaneously."
One volunteer, who was raised in the area and has been working to save its toad population since he was a child, notes that "Their sole purpose: to go and have an orgy." If their route crosses a road, they could all get run over, and that breeding season would be lost – preventing a new generation of toads from being born.
Toad Patrols Across the United Kingdom
Finding hundreds of toad carcasses on nearby streets "resonates deeply with people," and has resulted in the creation of rescue teams throughout the UK – 274 groups are officially listed with a countrywide program. These teams collect toads and transport them over streets in buckets, as well as recording the number of toads they encounter and advocating for other protection measures, such as road closures and amphibian passages.
Patrols usually work during the breeding period, when amphibian movements are frequent. However, this means they can miss groups of young toads, which, having been eggs and then tadpoles, exit their ponds over an irregular timetable in the end of summer. Because of their size – just one or two centimetres wide – "they can get obliterated by car traffic." And as being hit "basically turns them into mush," it's harder to collect information on them. At least when mature amphibians are lost, their carcasses can be counted.
Year-Round Efforts
In contrast to many groups, one local team, who are in their eighth year of operating, go out throughout the year – not every night, but whenever conditions are warm and wet, or if someone has posted about a amphibian spotting in their group chat. When I ask to join them on patrol, they admit it is "not ideal conditions" – winter dormancy has begun and it's been a dry day – but a few of the volunteers willingly accept to patrol their route with me and search for any toads. "If anyone can locate any toads tonight, that pair will find one," says the patrol manager, pointing to her 14-year-old son and the longtime volunteer. After for two hours without a glimpse of any amphibians, and now they have scaled a barbed wire fence to check under some wood.
Family Involvement
The mother and son became part of the patrol a year and a half ago. The youngster adores all things nature-related and has an ambition to become a conservationist, so his parent started to search for activities they could do together to protect local wildlife. Now she loves it as much as he does, the 41-year-old small business owner explains – so when the group was seeking a new manager recently, she volunteered for the role.
The youth, too, has been instrumental in the group. A clip he created, urging the local council to close a street through a protected area during breeding time, swung the decision the group's way. After a twelve months of campaigning, the council approved an "restricted access" rule between 5pm and 5am from late winter through to spring. Most drivers respected and avoided the road.
Additional Species and Challenges
Several vehicles go past when I'm out on duty and we discover some victims as a result – no amphibians, but several crushed salamanders. We spot one living newt as well, and the youngster is especially excited to see a daddy longlegs, which moves in his hands. Yet despite the group's best efforts to let me see a toad, the native community has clearly gone dormant for the winter. It appears that I couldn't have found any better success anywhere else in the nation – all the rescue teams I reach out to explain that it's very difficult at this season.

One email I receive from a different helper, who has kindly made the effort to check for toads in a noted location, thought to be the biggest tracked toad group in the UK, reaches me with the subject line: "None found." However, in February and March, he informs me, the team plans to assist approximately 10,000 mature amphibians across the road.
Impact and Limitations
How much of a difference can these organizations actually make? "The fact that people are doing this consistently on chilly, wet and miserable evenings is quite extraordinary," notes an researcher. "That's something that very much should be celebrated." However, while rescue teams are able to reduce the drop, they cannot prevent it entirely – not least because traffic is just one danger.
Additional Threats
The global warming has resulted in extended spells of drought, which create the poor environment for some of the animals that toads eat, such as invertebrates, while higher water temperatures have led to an rise of toxic plants, which can be harmful to toads. Milder winters also lead toads to wake up from their hibernation more often, interfering with the resource preservation vital to their existence. Loss of environment – especially the loss of large ponds – is an additional threat.
Researchers are "always a bit worried about putting too much of a utilitarian spin on wildlife," but "It's important in just having these animals around." But toads do have an significant part in the ecosystem, consuming pretty much any small creatures or tiny organisms they can fit in their mouths and in turn feeding a variety of predators, such as hedgehogs and otters. Enhancing conditions for toads – such as building water habitats, protecting forests and installing toad tunnels – "benefits for a wide range of other species."
Historical Significance
An additional motive to try to keep toads present is their "historical significance," notes an specialist. Legends and tales around toads go back {centuries|hundred
