Can the UK's Toads Survive from Roads and Terrible Decline?
It's a Friday night at half past seven, but instead of going out or relaxing at home, I've caught a train to a town in Wiltshire to join local helpers from a toad patrol. These committed people sacrifice their evenings to protect the local toad population.
A Worrying Decline in Numbers
The common toad is becoming increasingly uncommon. A latest research led by an wildlife conservation group revealed that the British common toad numbers have almost halved since 1985. Observing a creature that has been a stalwart of the UK landscape in decrease is labeled "worrying" by experts. Toads "don't require very specific conditions" and "should be able to live quite well in the majority of areas in Britain," meaning if even they are not managing to survive, "it indicates that things are not as they should be."

The Danger from Traffic
Though the research didn't cover the causes for the drop, traffic certainly plays a part. Estimates suggest that 20 tons of toads are crushed on UK roads annually – that is, several hundred thousand. In contrast to frogs, which might be happy to mate "if you left out a bucket of water," toads favor big bodies of water. Their capacity to stay out of water for more time than frogs allows they can journey farther to reach them – often long distances. They tend to stick to their traditional paths – it's typical for mature amphibians to return to their birth pond to mate.
Breeding Patterns
Appropriately enough, the first toads begin their quest for a partner around February 14th, but others travel as late as spring, until it gets dark and moving through the night. During that period, toads begin migrating from wherever they have been hibernating "almost simultaneously."
One volunteer, who was raised in the region and has been working to save its toad population since he was a child, notes that "They've got just one focus: to go and have an orgy." If their route crosses a street, they could all get run over, and that mating period would never happen – stopping a next generation of toads from being produced.
Toad Patrols Throughout the UK
Finding many of toad carcasses on nearby streets "inherently strikes a chord with people," and has resulted in the creation of rescue teams throughout the UK – hundreds of organizations are currently registered with a countrywide program. These groups collect toads and transport them over streets in buckets, as well as counting the quantity of toads they encounter and lobbying for other protection measures, such as road closures and amphibian passages.
Patrols tend to operate during the breeding period, when amphibian movements are more regular. However, this means they can miss groups of toadlets, which, having been eggs and then juveniles, leave their water habitats over an irregular timetable in late summer. Because of their size – just one or two centimetres wide – "they can get obliterated by vehicles." And as being hit "essentially crushes them," it's more difficult to get data on them. At least when adult toads are killed, their carcasses can be tallied.
Year-Round Efforts
Unlike many groups, a specific volunteer group, who are in their eighth season of functioning, go out throughout the year – not every night, but when weather are warm and wet, or if someone has reported about a amphibian spotting 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 several of the volunteers willingly accept to walk up and down their area with me and search for any toads. "If anyone can locate any toads tonight, that pair will find one," says the group coordinator, indicating her 14-year-old son and the experienced member. We've been out for two hours without a single toad sighting, and now they have scaled a wire barrier to inspect beneath some logs.
Family Participation
The family duo became part of the group a while back. The youngster loves all things wildlife and has an goal to become a conservationist, so his mother started to search for activities they could do jointly to help local wildlife. Now she enjoys it as much as he does, the middle-aged small business owner explains – so when the group was looking for a fresh coordinator lately, she volunteered for the role.
The teenager, too, has been instrumental in the organization. A video he made, imploring the municipal authority to block a road through a protected area during breeding time, influenced the outcome the team's way. After a twelve months of lobbying, the authority agreed to an "restricted access" rule between evening and morning from February through to spring. The majority of motorists duly avoided the route.
Other Wildlife and Difficulties
A few vehicles go past when I'm out on duty and we find some victims as a consequence – no toads, but several crushed salamanders. We spot one live amphibian as well, and the youngster is particularly pleased to see a harvestman, which dances in his palms. Yet despite the team's hardest attempts to let me see a toad, the local population has obviously gone dormant for the colder months. It appears that I couldn't have found any more luck anywhere else in the country – all the rescue teams I contact clarify that it's near-impossible at this season.

A message I receive from a different helper, who has kindly taken the trouble to look for toads in a famous site, considered the biggest tracked toad group in the UK, arrives in my inbox with the subject line: "None found." However, in late winter, he tells me, the group expects to help around 10,000 adult toads across the road.
Impact and Challenges
How much of a difference can these groups actually make? "The fact that people are doing this regularly on cold, damp and unpleasant evenings is quite extraordinary," 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 – not least because vehicles is not the only threat.
Additional Threats
The climate crisis has meant longer periods of dry weather, which cause the wrong conditions for some of the animals that toads consume, such as invertebrates, while higher water temperatures have led to an rise of blue-green algae, which can be toxic to toads. Warmer cold seasons also cause toads to wake up from their hibernation more often, disrupting the energy conservation crucial to their life cycle. Loss of environment – particularly the disappearance of large ponds – is an additional threat.
Researchers are "often concerned about overemphasizing practical benefits on biodiversity," but "It's important in just having these animals around." But toads do have an significant part in the food chain, eating almost any invertebrates or tiny organisms they can fit in their mouths and in turn sustaining a variety of birds and mammals, such as hedgehogs and otters. Enhancing situations for toads – ie creating more ponds, conserving woodland and constructing amphibian passages – "benefits for a whole bunch of additional wildlife."
Cultural Significance
An additional motive to work to preserve toads present is their "historical significance," notes an specialist. Myths and folklore around toads date back {centuries|hundred
