Will Britain's Common Toads Survive from Traffic and Terrible Decline?
It's Friday evening at half past seven, but instead of heading to the pub or relaxing at home, I've taken a train to a market town in the countryside to join local helpers from a toad patrol. These dedicated individuals sacrifice their nights to safeguard the native amphibian community.
A Worrying Drop in Population
The Bufo bufo is growing more rare. A latest study led by an amphibian and reptile charity revealed that the British common toad numbers have almost halved since the mid-1980s. Seeing a creature that has been a stalwart of the UK landscape in decline is labeled "concerning" by researchers. Toads "don't need very particular environments" and "should be able to live quite well in most of habitats in Britain," meaning if even they are not managing to survive, "it indicates that the ecosystem is unbalanced."

The Threat from Roads
Though the research didn't examine the reasons for the drop, traffic is a major factor. Calculations indicate that 20 tons of toads are crushed on British 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 large ponds. Their ability to stay out of water for more time than frogs means they can travel further to find them – sometimes long distances. They usually follow their ancestral migration routes – it's typical for adult toads to return to their birth pond to mate.
Migration Patterns
Fittingly, the first toads begin their quest for a partner around February 14th, but some move as far as spring, until it gets night and moving through the night. During that time, toads start moving from where they have been hibernating "all pretty much at the same time."
A local helper, who was raised in the area and has been working to save its toad population since he was a boy, explains that "They've got just one focus: to go and mate." If their path happens to a road, they could be killed by traffic, and that mating period would never happen – stopping a new generation of toads from being born.
Toad Patrols Across the UK
Finding hundreds of dead toads on nearby streets "inherently strikes a chord with people," and has resulted in the creation of toad patrols throughout the UK – hundreds of organizations are officially listed with a national initiative. These teams collect toads and carry them across roads in containers, as well as recording the number of toads they find and advocating for other protection measures, such as road closures and amphibian passages.
Patrols tend to operate during the migration season, when amphibian movements are more regular. However, this implies they can overlook numbers 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 a couple of cm wide – "they can get obliterated by car traffic." And as being run over "essentially crushes them," it's more difficult to get data on them. At least when adult toads are lost, their remains can be tallied.
Year-Round Work
In contrast to many groups, a specific volunteer group, who are in their eighth season of functioning, go out throughout the year – not nightly, but when conditions are warm and wet, or if a member has reported about a toad sighting in their messaging app. When I ask to join them on duty, they admit it is "not a toady night" – toad hibernation season has started 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 see what we can find. "If anyone can locate any toads tonight, those two will find one," says the group coordinator, pointing to her teenage child and the experienced member. After for 120 minutes without a glimpse of any amphibians, and now they have climbed over a barbed wire fence to check under some wood.
Community Involvement
The family duo joined the group a year and a half ago. The youngster loves all things nature-related and has an goal to become a conservationist, so his mother started to search for things they could do jointly to protect local wildlife. Now she enjoys it as much as he does, the middle-aged small business owner explains – so when the team was seeking a new manager recently, she volunteered for the role.
The teenager, too, has been instrumental in the organization. A clip he made, imploring the local council to close a street through a nature reserve during breeding time, influenced the outcome the group's way. After a year of lobbying, the authority agreed to an "restricted access" rule between evening and morning from February through to April. The majority of motorists respected and avoided the road.
Other Wildlife and Difficulties
A few cars go past when I'm out on duty and we find some victims as a consequence – no toads, but three squashed newts. We see one live amphibian as well, and the youngster is especially excited to see a harvestman, which moves in his palms. Yet in spite of the team's hardest attempts to let me see a toad, the local population has clearly settled down for the winter. It seems that I couldn't have found any better success elsewhere in the country – all the rescue teams I contact clarify that it's near-impossible at this season.
This team anticipates assisting around ten thousand mature toads over the street
A message I receive from another volunteer, who has kindly taken the trouble to check for toads in a famous site, considered the biggest tracked toad population in the UK, reaches me with the subject line: "None found." However, in late winter, he tells me, the group expects to help around ten thousand adult toads across the road.
Impact and Challenges
How much of a difference can these groups actually make? "The reality that people are performing this regularly on cold, damp and unpleasant late nights is quite extraordinary," 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 – partly since traffic is not the only threat.
Other Dangers
The global warming has meant extended spells of drought, which create the wrong conditions for some of the animals that toads eat, such as invertebrates, while warmer ponds have led to an increase 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 resource preservation crucial to their existence. Loss of environment – particularly the disappearance of big water bodies – is an additional threat.
Experts are "often concerned about overemphasizing practical benefits on biodiversity," but "There is a big value in just having these animals around." But toads do have an significant part in the food chain, consuming almost any invertebrates or tiny organisms they can swallow and in turn feeding a number of predators, such as hedgehogs and otters. Improving conditions for toads – such as building water habitats, protecting forests and constructing amphibian passages – "we'll improve them for a wide range of additional wildlife."
Cultural Significance
An additional motive to try to keep toads around is their "historical significance," notes an expert. Legends and tales around toads date back {centuries|hundred
