It's a Friday night at 7:30, 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 toad patrol. These dedicated individuals sacrifice their evenings to protect the native amphibian community.

A Worrying Decline in Population

The common toad is growing more uncommon. A recent study conducted by an amphibian and reptile charity showed that the UK toad population have almost halved since the mid-1980s. Seeing a creature that has been a fixture of the UK landscape in decline is described as "worrying" by researchers. Toads "don't require very particular environments" and "should be able to live successfully in the majority of areas in Britain," meaning if even they are struggling to persist, "it kind of suggests that the ecosystem is unbalanced."

The Danger from Roads

Though the research didn't cover the reasons for the drop, traffic certainly plays a part. Estimates suggest that 20 tonnes of toads are crushed on British roads annually – in other words, several hundred thousand. In contrast to frogs, which might be happy to mate "if you left out a small container," toads favor large ponds. Their ability to stay out of water for longer than frogs allows they can journey farther to find them – often long distances. They tend to stick to their traditional paths – it's common for mature amphibians to go back to their birth pond to mate.

Breeding Habits

Fittingly, the initial amphibians start their journey for a partner around February 14th, but others travel as late as spring, until it gets night and moving through the night. During that time, toads begin migrating from where they have been overwintering "all pretty much at the same time."

A local helper, 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 crosses a street, they could all get run over, and that breeding season would never happen – preventing a new generation of toads from being born.

Rescue Groups Across the United Kingdom

Finding hundreds of toad carcasses on nearby streets "resonates deeply with people," and has resulted in the creation of rescue teams throughout the UK – 274 groups are currently registered with a countrywide program. These groups collect toads and transport them across roads in buckets, as well as counting the number of toads they encounter and lobbying for other safety solutions, such as blocked roads and underground wildlife tunnels.

Volunteers usually work during the breeding period, when toad crossings are more regular. However, this implies they can miss numbers of young toads, which, having been spawn and then tadpoles, leave their ponds over an unpredictable schedule in the end of summer. Because of their size – just a couple of cm wide – "they can get obliterated by car traffic." And as being hit "basically turns them into mush," it's harder to collect information on them. At least when adult toads are lost, their carcasses can be tallied.

Annual Efforts

Unlike many groups, one local team, who are in their eighth season of functioning, go out year-round – not nightly, but when weather are damp, or if a member has posted about a amphibian spotting in their messaging app. When I request to accompany them on duty, they admit it is "not ideal conditions" – winter dormancy has started and it's been a dry day – but several of the volunteers gamely agree to patrol their route with me and search for any toads. "If anyone can find any toads tonight, those two will find one," says the patrol manager, indicating her teenage child and the longtime volunteer. After for two hours without a single toad sighting, and now they have climbed over a barbed wire fence to inspect beneath some wood.

Family Involvement

The mother and son joined the group a while back. The youngster adores all things nature-related and has an ambition to become a environmentalist, so his mother started to look for things they could do jointly to protect local wildlife. Now she enjoys it as much as he does, the middle-aged small business owner explains – so when the group was looking for a new manager recently, she volunteered for the role.

The teenager, too, has been instrumental in the organization. A video he created, urging the local council to close a street through a nature reserve during breeding time, influenced the outcome the team's way. After a twelve months of campaigning, the council agreed to an "access-only" rule between evening and morning from late winter through to spring. Most drivers duly avoided the route.

Other Wildlife and Challenges

A few vehicles go past when I'm out on duty and we discover some casualties as a consequence – no amphibians, but several crushed salamanders. We spot one living newt as well, and the teenager is especially excited to see a daddy longlegs, which dances in his hands. Yet in spite of the team's hardest attempts to let me see a toad, the local population has obviously settled down for the winter. It seems that I couldn't have found any better success anywhere else in the country – all the rescue teams I reach out to explain that it's very difficult at this season.

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

One email I get from a different helper, who has kindly taken the trouble to look for toads in a famous site, thought to be the largest accurately monitored toad population in the UK, reaches me with the subject line: "No toads." However, in February and March, he informs me, the team plans to assist approximately ten thousand mature amphibians over the street.

Impact and Challenges

What level of impact can these groups actually make? "The reality that people are performing this consistently on chilly, wet and miserable evenings is quite extraordinary," says an researcher. "This effort that very much should be celebrated." However, while rescue teams are able to reduce the drop, they cannot prevent it entirely – partly since vehicles is just one danger.

Other Dangers

The climate crisis has meant extended spells of drought, which create the poor environment for some of the creatures that toads consume, such as worms and slugs, while higher water temperatures have caused an rise of toxic plants, which can be harmful to toads. Warmer cold seasons also lead toads to emerge from their hibernation more often, disrupting the resource preservation vital to their existence. Loss of environment – especially the loss of big water bodies – is an additional threat.

Experts are "always a bit worried about putting too much of a utilitarian spin on biodiversity," however "There is a big value in just their presence." But toads play an significant part in the food chain, eating pretty much any invertebrates or small animals they can swallow and in turn sustaining a number of birds and mammals, such as hedgehogs and otters. Improving conditions for toads – ie creating more ponds, conserving woodland and installing toad tunnels – "we'll improve them for a whole bunch of other species."

Cultural Importance

Another reason to try to keep toads around is their "important cultural value," notes an specialist. Legends and tales around toads go back {centuries|hundred
