Can the UK's Common Toads Be Saved from Traffic and Population Collapse?
It's Friday night at half past seven, but instead of going out or watching a film, I've taken a train to a town in the countryside to meet up with local helpers from a toad patrol. These committed people sacrifice their nights to protect the native amphibian community.
An Alarming Drop in Numbers
The common toad is becoming increasingly rare. A latest study conducted by an amphibian and reptile charity revealed that the British common toad numbers have dropped by half since 1985. Seeing a creature that has been a fixture of the UK landscape in decrease is labeled "concerning" by experts. Toads "don't require very particular environments" and "should be able to live quite well in the majority of areas in Britain," so if even they are not managing to survive, "it indicates that things are not as they should be."

The Danger from Roads
Though the research didn't cover the reasons for the drop, cars certainly plays a part. Calculations suggest that 20 tons of toads are killed on UK roads every year – that is, several hundred thousand. Unlike frogs, which would probably be happy to mate "with just a bucket of water," toads prefer big bodies of water. Their ability to stay out of water for more time than frogs allows they can travel further to find them – sometimes hundreds of metres. They tend to stick to their traditional paths – it's typical for adult toads to return to their birth pond to mate.
Breeding Patterns
Appropriately enough, 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 travelling after sunset. During that period, toads begin migrating from wherever they have been hibernating "all pretty much at the same time."
One volunteer, who grew up in the area and has been trying to protect its toad population since he was a boy, notes that "They've got just one focus: to go and have an orgy." If their path happens to a street, they could be killed by traffic, and that mating period would never happen – preventing a new generation of toads from being born.
Rescue Groups Across the United Kingdom
Finding many of toad carcasses on local roads "inherently strikes a chord with people," and has resulted in the formation of toad patrols throughout the UK – hundreds of organizations are officially listed with a national initiative. These teams pick up toads and carry them across roads in containers, as well as counting the quantity of toads they encounter and lobbying for other protection measures, such as blocked roads and amphibian passages.
Volunteers tend to operate during the migration season, when amphibian movements are frequent. However, this implies they can overlook numbers of young toads, which, having existed as eggs and then juveniles, exit their ponds over an irregular timetable in the end of summer. Because of their size – just a couple of cm wide – "they can get obliterated by vehicles." And as being run over "essentially crushes them," it's harder to collect information on them. At least when adult toads are lost, their remains can be tallied.
Annual Work
Unlike most patrols, one local team, who are in their eighth year of functioning, go out throughout the year – not every night, but when conditions are damp, or if someone has posted about a amphibian spotting in their group chat. When I ask to join them on duty, they admit it is "not ideal conditions" – winter dormancy has started and it's been a arid period – but a few of the helpers gamely agree 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 find one," says the patrol manager, pointing to her teenage child and the experienced member. After for 120 minutes without a single toad sighting, and now they have scaled a barbed wire fence to inspect beneath some logs.
Community Participation
The family duo became part of the group a year and a half ago. The teenager loves all things wildlife and has an ambition to become a environmentalist, so his mother started to search for things they could do jointly to help local wildlife. Now she loves it as much as he does, the 41-year-old entrepreneur tells me – so when the group was seeking a new manager lately, she decided to step up.
The teenager, too, has played an important role in the organization. A video he created, urging the municipal authority to block a road through a nature reserve during breeding time, swung the decision the team's way. After a twelve months of lobbying, the council approved an "restricted access" rule between evening and morning from February through to spring. Most drivers duly avoided the route.
Additional Species and Challenges
Several cars go by when I'm out on duty and we discover some victims as a result – no amphibians, but three squashed newts. We see one live amphibian as well, and the teenager is especially excited to see a daddy longlegs, which moves in his hands. Yet despite the group's best efforts to show me a toad, the native community has obviously settled down for the winter. It appears that I couldn't have found any better success elsewhere in the country – all the rescue teams I reach out to clarify that it's very difficult at this season.

One email I get from a different helper, who has generously taken the trouble to check for toads in a noted location, thought to be the largest accurately monitored toad group in the UK, reaches me with the title: "No toads." However, in February and March, he informs me, the group plans to assist approximately 10,000 adult toads across the road.
Effectiveness and Limitations
How much of a difference can these organizations actually make? "The fact that people are doing this regularly on cold, damp and unpleasant evenings is remarkable," notes an researcher. "This effort that very much deserves recognition." However, while toad patrols are able to reduce the drop, they cannot prevent it entirely – partly since vehicles is not the only threat.
Other Dangers
The climate crisis has resulted in longer periods of drought, which cause the poor environment for some of the creatures that toads eat, such as worms and slugs, while higher water temperatures have led to an increase of blue-green algae, which can be harmful to toads. Warmer cold seasons also lead toads to wake up from their hibernation more frequently, interfering with the energy conservation crucial to their existence. Habitat destruction – especially the loss of big water bodies – is another menace.
Experts are "always a bit worried about overemphasizing practical benefits on wildlife," but "It's important in just their presence." But toads play an significant part in the ecosystem, eating 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 wildlife. Enhancing situations for toads – ie creating more ponds, protecting forests and constructing toad tunnels – "benefits for a whole bunch of other species."
Historical Importance
Another reason to try to keep toads around is their "important cultural value," adds an specialist. Myths and folklore around toads go back {centuries|hundred
