It is Friday evening at half past seven, but rather than heading to the pub or relaxing at home, I've caught a train to a town in the countryside to meet up with local helpers from a toad patrol. These dedicated individuals give up their evenings to protect the local toad population.

An Alarming Drop in Numbers

The Bufo bufo is growing more uncommon. A latest study conducted by an amphibian and reptile charity revealed that the British common toad numbers have dropped by half since the mid-1980s. Seeing a species that has been a fixture of the British countryside in decrease is described as "concerning" by experts. Toads "don't require very specific conditions" and "should be able to live successfully in the majority of habitats in Britain," so if even they are struggling to persist, "it indicates that the ecosystem is unbalanced."

The UK toad population has almost halved since 1985

The Threat from Roads

Though the study didn't cover the reasons for the drop, traffic certainly plays a part. Estimates indicate that 20 tonnes of toads are crushed on UK roads annually – in other words, hundreds of thousands. In contrast to frogs, which would probably be happy to mate "if you left out a small container," toads prefer big bodies of water. Their ability to remain away from water for more time than frogs means they can journey farther to find them – often hundreds of metres. They usually stick to their ancestral migration routes – it's typical for adult toads to go back to their birth pond to mate.

Breeding Habits

Appropriately enough, the first toads begin their quest for a partner around Valentine's day, but some move as far as April, until it gets night and moving through the night. During that time, toads begin migrating from where they have been hibernating "all pretty much at the same time."

One volunteer, who grew up in the area and has been working to save its amphibians 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 all get run over, and that breeding season would be lost – preventing a next generation of toads from being born.

Rescue Groups Throughout the UK

Seeing hundreds of toad carcasses on local roads "resonates deeply with people," and has resulted in the creation of rescue teams across the UK – 274 groups are officially listed with a countrywide program. These groups collect toads and transport them across roads in containers, as well as counting the number of toads they find and advocating for other safety solutions, such as road closures and amphibian passages.

Patrols usually work during the breeding period, when toad crossings are frequent. However, this means they can overlook groups of young toads, which, having been spawn and then juveniles, exit their ponds over an irregular timetable in late summer. Because of their small stature – just one or two centimetres wide – "they can get obliterated by car traffic." And as being hit "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 tallied.

Annual Work

In contrast to 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 warm and wet, or if someone has posted about a toad sighting 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 willingly accept to walk up and down their area with me and see what we can find. "Should anyone can locate any toads tonight, that pair will spot one," says the group coordinator, pointing to 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 climbed over a wire barrier to inspect beneath some wood.

Community Involvement

The mother and son became part of the group a year and a half ago. The youngster adores all things nature-related and has an ambition to become a environmentalist, so his parent started to look for things they could do together to help local wildlife. Now she enjoys it as much as he does, the 41-year-old entrepreneur tells me – so when the team was seeking a new manager lately, she volunteered for the role.

The youth, too, has played an important role in the organization. A video he created, urging the municipal authority to block a road through a protected area during migration season, swung the decision the team's way. After a twelve months of lobbying, the authority approved an "restricted access" rule between evening and morning from late winter through to April. Most drivers duly avoided the route.

Additional Species and Difficulties

Several vehicles go by when I'm out on patrol and we discover some victims as a consequence – no amphibians, but several crushed salamanders. We see one live amphibian as well, and the teenager is especially excited to see a daddy longlegs, which moves in his hands. Yet in spite of the group's hardest attempts to show me a toad, the native community has clearly settled down for the winter. It appears that I couldn't have found any more luck anywhere else in the country – all the patrol groups I reach out to explain that it's very difficult at this time of year.

The group expects to help approximately 10,000 adult toads across the road

One email I receive from another volunteer, who has generously made the effort to look for toads in a famous site, considered the largest accurately monitored toad population in the UK, arrives in my inbox with the subject line: "No toads." However, in late winter, he tells me, the group expects to help approximately 10,000 adult toads across the road.

Effectiveness and Challenges

How much of a difference can these organizations truly achieve? "The reality that people are doing this consistently 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 just one danger.

Other Dangers

The global warming has meant extended spells of drought, which create the wrong conditions for some of the creatures that toads consume, such as invertebrates, while warmer ponds have caused an rise of toxic plants, which can be harmful to toads. Milder winters also cause toads to wake up from their dormancy more often, interfering with the energy conservation crucial to their life cycle. Loss of environment – especially the disappearance of large ponds – is an additional threat.

Experts are "always a bit worried about overemphasizing practical benefits on wildlife," however "There is a big value in just having these animals around." But toads do have an important role in the food chain, eating almost any small creatures or tiny organisms they can swallow and in turn sustaining a number of predators, such as wildlife. Improving situations for toads – such as building water habitats, conserving woodland and constructing amphibian passages – "benefits for a whole bunch of additional wildlife."

Cultural Importance

Another reason to try to keep toads present is their "important cultural value," adds an specialist. Myths and folklore around toads date back {centuries|hundred
