Can Britain's Toads Be Saved from Roads and Population Collapse?
It is a Friday evening at half past seven, but rather than going out or relaxing at home, I've caught a train to a town in the countryside to join local helpers from a toad patrol. These committed people give up their nights to safeguard the local toad population.
A Worrying Drop in Population
The common toad is becoming increasingly uncommon. A latest study led by an wildlife conservation group revealed that the British common toad numbers have almost halved since the mid-1980s. Observing a creature that has been a fixture of the British countryside in decline is described as "concerning" by experts. Toads "don't require very particular environments" and "ought to live successfully in most of areas in the UK," so if even they are not managing to survive, "it indicates that the ecosystem is unbalanced."

The Threat from Traffic
Though the research didn't cover the causes for the decline, traffic is a major factor. Estimates indicate that 20 tons of toads are killed on British roads every year – that is, hundreds of thousands. In contrast to frogs, which might be happy to mate "if you left out a bucket of water," toads favor large ponds. Their capacity to stay out of water for more time than frogs allows they can journey farther to find them – sometimes hundreds of metres. They usually follow their traditional paths – it's common for mature amphibians to go back to their birth pond to mate.
Migration Patterns
Appropriately enough, the first toads start their journey for a mate around February 14th, but some move as late as spring, until it gets night and moving after sunset. During that period, toads begin migrating from wherever they have been overwintering "all pretty much at the same time."
One volunteer, who was raised in the region and has been trying to protect its toad population since he was a child, explains that "They've got just one focus: to go and mate." If their path crosses a road, they could all get run over, and that breeding season would be lost – stopping a new generation of toads from being produced.
Toad Patrols Across the United Kingdom
Finding many of dead toads on nearby streets "inherently strikes a chord with people," and has led to the creation of toad patrols across the UK – hundreds of organizations are officially listed with a national initiative. These teams collect toads and carry them across roads in buckets, as well as recording the quantity of toads they encounter and advocating for other safety solutions, such as blocked roads and amphibian passages.
Volunteers usually work during the breeding period, when amphibian movements are more regular. However, this implies they can overlook groups of young toads, which, having existed as eggs and then juveniles, leave their water habitats over an irregular timetable in the end of summer. Because of their small stature – just one or two centimetres wide – "they are destroyed by car traffic." And as being run over "basically turns them into mush," it's more difficult to get data on them. At least when mature amphibians are lost, their carcasses can be counted.
Annual Work
Unlike many groups, a specific volunteer group, who are in their eighth season of operating, go out throughout the year – not nightly, but whenever weather are damp, or if someone has reported about a toad sighting in their messaging app. When I request to accompany 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 helpers gamely agree to walk up and down their area with me and search for any toads. "If anyone can find any toads tonight, that pair will find one," says the patrol manager, indicating her teenage child and the experienced member. After for two hours without a single toad sighting, and now they have climbed over a wire barrier to inspect beneath some wood.
Community Involvement
The family duo joined the patrol a year and a half ago. The youngster adores all things wildlife and has an ambition to become a environmentalist, so his parent started to search for activities they could do jointly to protect local wildlife. Now she enjoys it as much as he does, the middle-aged entrepreneur tells me – so when the group was looking for a new manager recently, she decided to step up.
The youth, too, has been instrumental in the group. A clip he made, imploring the local council to block a street through a nature reserve during migration season, swung the decision the group's way. After a twelve months of lobbying, the authority approved an "access-only" restriction between 5pm and 5am from late winter through to spring. Most drivers duly avoided the road.
Additional Species and Difficulties
A few vehicles go past when I'm out on duty and we find some casualties as a consequence – no amphibians, but several crushed salamanders. We spot one living newt as well, and the youngster is particularly pleased to see a daddy longlegs, which dances in his palms. Yet despite the group's best efforts to show me a toad, the local population has clearly gone dormant for the colder months. It appears that I couldn't have found any better success anywhere else in the country – all the patrol groups I reach out to explain that it's near-impossible at this season.

One email I receive from another volunteer, who has generously taken the trouble to check for toads in a famous site, considered the biggest tracked toad population in the UK, arrives in my inbox with the subject line: "None found." However, in February and March, he informs me, the team expects to help around ten thousand mature amphibians across the road.
Effectiveness and Limitations
What level of impact can these organizations actually make? "The fact that volunteers are performing this regularly on chilly, wet and miserable evenings is quite extraordinary," notes an researcher. "This effort that very much deserves recognition." However, while rescue teams are able to reduce the drop, they cannot prevent it entirely – not least because traffic is just one danger.
Other Dangers
The climate crisis has resulted in longer periods of drought, which cause the poor environment for some of the creatures that toads consume, such as invertebrates, while higher water temperatures have led to an rise 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 energy conservation vital to their existence. Habitat destruction – particularly the disappearance of big water bodies – is another menace.
Experts are "often concerned about putting too much of a utilitarian spin on wildlife," however "It's important in just having these animals around." But toads play an important role in the food chain, eating almost any small creatures 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 wide range of other species."
Cultural Significance
An additional motive to try to keep toads around is their "important cultural value," notes an expert. Myths and folklore around toads go back {centuries|hundred
