It's Friday evening at half past seven, but instead of heading to the pub or watching a film, I've taken a train to a market town in Wiltshire to meet up with volunteers from a amphibian rescue group. These dedicated individuals give up their nights to safeguard the native amphibian community.

A Worrying Drop in Numbers

The Bufo bufo is becoming increasingly rare. A recent study conducted by an amphibian and reptile charity showed that the UK toad population have almost halved since the mid-1980s. Observing a species that has been a fixture of the UK landscape in decrease is labeled "worrying" by researchers. Toads "don't require very specific conditions" and "should be able to live successfully in the majority of areas in Britain," meaning 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 drop, traffic is a major factor. Estimates suggest that 20 tonnes of toads are crushed on UK roads every year – in other words, several hundred thousand. In contrast to frogs, which would probably be content to mate "if you left out 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 – often hundreds of metres. They tend to stick to their traditional paths – it's typical for adult toads to go back to their natal pond to mate.

Breeding Patterns

Appropriately enough, the first toads start their journey for a partner around Valentine's day, but others travel as late as spring, waiting until it gets dark and travelling after sunset. During that time, toads begin migrating from where they have been overwintering "almost simultaneously."

One volunteer, who grew up in the region and has been working to save its toad population since he was a boy, notes that "Their sole purpose: to go and have an orgy." If their path happens to a street, they could be killed by traffic, and that mating period would be lost – stopping a new generation of toads from being produced.

Rescue Groups Throughout the UK

Finding hundreds of toad carcasses on nearby streets "inherently strikes a chord with people," and has resulted in the creation of rescue teams across the UK – 274 groups are currently registered with a national initiative. These teams pick up toads and transport them across roads in buckets, as well as counting the number of toads they encounter and advocating for other protection measures, such as road closures and amphibian passages.

Patrols tend to operate during the breeding period, when toad crossings are more regular. However, this means they can miss numbers of toadlets, which, having been eggs and then juveniles, exit their ponds over an irregular timetable in the end of summer. Because of their small stature – just one or two centimetres wide – "they can get obliterated by vehicles." And as being hit "essentially crushes them," it's more difficult to collect information on them. At least when mature amphibians are killed, their carcasses can be tallied.

Year-Round Work

In contrast to many groups, a specific volunteer group, who are in their eighth season of operating, go out throughout the year – not every night, but when weather are warm and wet, or if someone has posted about a toad sighting in their messaging app. When I ask to join them on patrol, they concede it is "not a toady night" – winter dormancy has begun and it's been a dry day – but several of the helpers gamely agree to walk up and down their route with me and see what we can find. "Should anyone can locate any toads tonight, those two will find one," says the patrol manager, pointing to her 14-year-old son and the longtime volunteer. We've been out for 120 minutes without a single toad sighting, and now they have scaled a barbed wire fence to check under some logs.

Family Involvement

The family duo joined 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 activities they could do jointly to protect native animals. Now she loves it as much as he does, the 41-year-old entrepreneur explains – so when the group was seeking a new manager recently, she volunteered for the role.

The youth, too, has been instrumental in the organization. A video he created, imploring the municipal authority to close a road through a nature reserve during breeding time, influenced the outcome the team's way. After a twelve months of lobbying, the council agreed to an "access-only" rule between evening and morning from February through to spring. Most drivers duly avoided the route.

Other Wildlife and Challenges

A few cars go past when I'm out on duty and we find some casualties as a consequence – no toads, but several crushed salamanders. We spot one living newt as well, and the teenager is especially excited to see a harvestman, which moves in his hands. Yet in spite of the team's best efforts to show me a toad, the native community has obviously settled down for the colder months. It seems that I couldn't have found any more luck elsewhere in the country – all the rescue teams 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 famous site, considered the largest accurately monitored toad population in the UK, reaches me with the subject line: "None found." However, in late winter, he tells me, the team plans to assist around ten thousand adult toads across the road.

Impact and Challenges

How much of a difference can these groups truly achieve? "The reality that people are doing this regularly on chilly, wet and miserable late nights 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 just one danger.

Additional Threats

The global warming has meant extended spells of dry weather, which create the poor environment for some of the creatures that toads eat, such as worms and slugs, while warmer ponds have led to an rise of blue-green algae, which can be harmful to toads. Milder winters also cause toads to emerge from their dormancy more often, disrupting the resource preservation vital to their existence. Loss of environment – especially the disappearance of large ponds – is an additional threat.

Researchers are "always a bit worried about putting too much of a utilitarian spin on biodiversity," however "It's important in just their presence." But toads do have an significant part in the ecosystem, eating almost any small creatures or tiny organisms they can swallow and in turn sustaining a variety of predators, such as hedgehogs and otters. Enhancing situations for toads – such as building water habitats, conserving woodland and installing amphibian passages – "we'll improve them for a wide range of additional wildlife."

Cultural Significance

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