Will Britain's Toads Survive from Traffic and Terrible Decline?
It is a Friday night at half past seven, but instead of heading to the pub or watching a film, I've caught a train to a market town in Wiltshire to join volunteers from a toad patrol. These dedicated individuals sacrifice their evenings to safeguard the local toad population.
A Worrying Decline in Population
The Bufo bufo is growing more rare. A latest research led by an wildlife conservation group revealed that the British common toad numbers have almost halved since 1985. Seeing a species that has been a fixture of the UK landscape in decrease is labeled "worrying" by experts. Toads "don't need very specific conditions" and "should be able to live successfully in the majority of habitats in Britain," so if even they are not managing to survive, "it indicates that the ecosystem is unbalanced."

The Danger from Traffic
Though the study didn't cover the causes for the drop, traffic certainly plays a part. Calculations suggest that 20 tonnes of toads are crushed on UK roads every year – in other words, several hundred thousand. In contrast to frogs, which might be content to mate "if you left out a small container," toads favor big bodies of water. Their capacity to remain away from water for more time than frogs allows they can travel further to find them – sometimes long distances. They usually stick to their traditional paths – it's typical for adult toads to go back to their natal pond to mate.
Breeding Habits
Fittingly, the first toads begin their quest for a mate around February 14th, but some move as far as spring, waiting until it gets night and moving through the night. During that period, toads start moving from wherever they have been overwintering "almost simultaneously."
A local helper, who was raised in the region and has been trying to protect its amphibians since he was a boy, notes that "Their sole purpose: to go and mate." If their path crosses a street, they could all get run over, and that mating period would be lost – stopping a new generation of toads from being produced.
Toad Patrols Throughout the United Kingdom
Finding many of dead toads on nearby streets "resonates deeply 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 groups collect toads and transport them across roads in containers, as well as recording the quantity of toads they encounter and lobbying for other safety solutions, such as road closures and underground wildlife tunnels.
Volunteers usually work 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, leave their ponds over an irregular timetable in late summer. Because of their size – just a couple of cm wide – "they are destroyed by car traffic." And as being hit "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 every night, but whenever weather are warm and wet, or if someone has posted about a amphibian spotting in their group chat. When I request to accompany them on patrol, 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 patrol their area with me and see what we can find. "Should anyone can find any toads tonight, those two will spot one," says the patrol manager, pointing to her teenage child and the experienced member. After for two hours without a single toad sighting, and now they have scaled a wire barrier to check under some logs.
Community Participation
The family duo joined the group a year and a half ago. The teenager adores all things nature-related and has an ambition to become a environmentalist, so his mother started to search for things they could do together to help 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 fresh coordinator recently, she decided to step up.
The youth, too, has played an important role in the organization. A clip he made, urging the municipal authority to block a street through a protected area during migration season, swung the decision the group's way. After a twelve months of campaigning, the council approved an "access-only" rule between evening and morning from late winter through to April. Most drivers respected and avoided the road.
Additional Species and Difficulties
A few cars go by when I'm out on duty and we find some casualties as a result – no toads, but several crushed salamanders. We spot one living newt as well, and the teenager is particularly pleased to see a harvestman, which moves in his palms. Yet in spite of the group's hardest attempts to let me see a toad, the local population has clearly gone dormant for the colder months. It seems that I couldn't have found any more luck elsewhere in the nation – all the rescue teams I contact explain that it's very difficult at this time of year.

A message I receive from a different helper, who has kindly made the effort to check for toads in a famous site, thought to be the biggest tracked toad group in the UK, arrives in my inbox with the title: "None found." However, in February and March, he informs me, the team plans to assist around 10,000 adult toads over the street.
Effectiveness and Challenges
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," 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 – partly since traffic is just one danger.
Other Dangers
The global warming has resulted in longer periods of drought, which create the poor environment for some of the creatures that toads consume, such as invertebrates, while warmer ponds have led to an rise of blue-green algae, which can be toxic to toads. Warmer cold seasons also cause toads to emerge from their dormancy more frequently, interfering with the energy conservation crucial to their existence. Habitat destruction – especially the disappearance of big water bodies – is another menace.
Researchers are "often concerned about overemphasizing practical benefits on wildlife," but "There is a big value in just their presence." But toads do have an significant part in the ecosystem, eating pretty much any small creatures or small animals they can fit in their mouths and in turn sustaining a variety of predators, such as wildlife. Improving conditions for toads – ie creating more ponds, conserving woodland and constructing amphibian passages – "we'll improve them for a whole bunch of additional wildlife."
Cultural Significance
An additional motive to try to keep toads present is their "important cultural value," adds an expert. Myths and folklore around toads date back {centuries|hundred
