It is Friday evening at half past seven, but rather than heading to the pub or watching a film, I've taken a train to a town in Wiltshire to join volunteers from a toad patrol. These dedicated individuals give up their nights to safeguard the native amphibian community.

An Alarming Drop in Numbers

The Bufo bufo is becoming increasingly uncommon. A latest study led by an wildlife conservation group revealed that the British common toad numbers have dropped by half since 1985. Observing a species that has been a stalwart of the UK landscape in decrease is described as "concerning" by experts. Toads "don't require very specific conditions" and "ought to live successfully in most of habitats in the UK," so if even they are struggling to persist, "it indicates that the ecosystem is unbalanced."

Since 1985, Britain's toad numbers have nearly been cut in half

The Danger from Traffic

Though the study didn't examine the causes for the drop, traffic certainly plays a part. Calculations indicate that 20 tonnes of toads are killed on UK roads every year – in other words, several hundred thousand. In contrast to frogs, which might be happy to mate "with just a bucket of water," toads prefer big bodies of water. Their capacity to remain away from water for more time than frogs means they can journey farther to find them – sometimes hundreds of metres. They tend to follow their traditional paths – it's common for adult toads to return to their natal pond to mate.

Migration Patterns

Appropriately enough, the initial amphibians start their journey for a partner around Valentine's day, but others travel as far as April, until it gets night and travelling through the night. During that time, toads begin migrating from wherever they have been hibernating "all pretty much at the same time."

One volunteer, who grew up in the area and has been trying to protect its toad population since he was a boy, explains that "Their sole purpose: to go and have an orgy." If their route crosses a street, they could be killed by traffic, and that breeding season would be lost – stopping a next generation of toads from being born.

Rescue Groups Across the United Kingdom

Finding many of dead toads on nearby streets "inherently strikes a chord with people," and has resulted in the creation of toad patrols across the UK – hundreds of organizations are currently registered with a national initiative. These teams pick up toads and transport them over streets in buckets, as well as recording the quantity of toads they encounter and lobbying for other safety solutions, such as road closures and amphibian passages.

Volunteers usually work during the breeding period, when toad crossings are frequent. However, this means they can overlook numbers of young toads, which, having been eggs and then juveniles, leave their ponds over an unpredictable schedule in late summer. Because of their size – just one or two centimetres wide – "they can get obliterated by car traffic." And as being run over "basically turns them into mush," it's harder to get data on them. At least when adult toads are killed, their remains can be counted.

Annual Efforts

In contrast to many groups, one local team, who are in their eighth year of operating, go out year-round – not nightly, but when weather are damp, or if someone has reported about a amphibian spotting in their group chat. When I request to accompany them on duty, they concede it is "not ideal conditions" – toad hibernation season has begun and it's been a dry day – but several of the helpers gamely agree to walk up and down their area with me and see what we can find. "Should anyone can locate any toads tonight, those two will spot one," says the group coordinator, indicating her 14-year-old son and the experienced member. We've been out for two hours without a glimpse of any amphibians, and now they have scaled a wire barrier to check under some logs.

Community Participation

The mother and son joined the group a while back. The youngster loves 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 native animals. Now she loves it as much as he does, the 41-year-old small business owner tells me – so when the team was looking for a fresh coordinator recently, she volunteered for the role.

The youth, too, has played an important role in the organization. A video he made, urging the municipal authority to close a street through a nature reserve during migration season, swung the decision the group's way. After a year of lobbying, the council agreed to an "access-only" restriction between 5pm and 5am 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 patrol and we discover some casualties as a result – no toads, but several crushed salamanders. We spot one live amphibian as well, and the teenager is particularly pleased to see a harvestman, which moves in his palms. Yet despite the group's best efforts to show me a toad, the local population has clearly settled down for the colder months. It appears that I couldn't have found any better success elsewhere in the nation – all the patrol groups I reach out to explain that it's near-impossible at this time of year.

This team anticipates assisting around ten thousand mature toads over the street

One email I get from another volunteer, who has generously taken the trouble to look for toads in a noted location, thought to be the largest accurately monitored toad group in the UK, arrives in my inbox with the title: "No toads." However, in February and March, he tells me, the team plans to assist approximately ten thousand adult toads over the street.

Impact and Limitations

How much of a difference can these organizations actually make? "The reality that people are performing this consistently on chilly, wet and miserable evenings is quite extraordinary," notes an expert. "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 vehicles is not the only threat.

Other Dangers

The climate crisis has meant extended spells of drought, which create the poor environment for some of the animals that toads consume, such as worms and slugs, while warmer ponds have caused an rise of toxic plants, which can be harmful to toads. Warmer cold seasons also lead toads to wake up from their hibernation more often, interfering with the resource preservation vital to their life cycle. Loss of environment – especially the disappearance of large ponds – is an additional threat.

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 significant part in the food chain, consuming almost any invertebrates or tiny organisms they can fit in their mouths and in turn feeding a variety of predators, such as hedgehogs and otters. Improving conditions for toads – such as building water habitats, conserving woodland and constructing toad tunnels – "we'll improve them for a whole bunch of additional wildlife."

Cultural Importance

Another reason to work to preserve toads present is their "historical significance," notes an specialist. Myths and folklore around toads go back {centuries|hundred
