It's a Friday night at 7:30, but instead of heading to the pub or relaxing at home, I've taken a train to a town in Wiltshire to meet up with 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 growing more uncommon. A latest study conducted by an wildlife conservation group showed that the UK toad population have dropped by half since 1985. Observing a creature that has been a stalwart of the British countryside in decline is described as "concerning" by researchers. Toads "don't require very particular environments" and "ought to live quite well in the majority of habitats in Britain," meaning if even they are struggling to persist, "it kind of suggests that the ecosystem is unbalanced."

The Threat from Roads

Though the study didn't examine the causes for the drop, cars certainly plays a part. Calculations indicate that 20 tonnes of toads are killed on British roads every year – in other words, several hundred thousand. Unlike frogs, which might be happy to mate "if you left out a bucket of water," toads prefer large ponds. Their ability to remain away from water for more time than frogs means they can journey farther to reach them – often long distances. They usually stick to their traditional paths – it's typical for mature amphibians to go back to their natal pond to mate.

Migration Patterns

Appropriately enough, the initial amphibians begin their quest for a partner around Valentine's day, but some move as late as April, until it gets night and moving through the night. During that period, toads start moving 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 toad population since he was a child, explains that "They've got just one focus: to go and have an orgy." If their path crosses a road, they could be killed by traffic, and that mating period would be lost – preventing a new generation of toads from being produced.

Toad Patrols Across the UK

Seeing hundreds of dead toads on nearby streets "resonates deeply with people," and has led to the formation of rescue teams throughout the UK – 274 groups are officially listed with a national initiative. These teams collect toads and carry them over streets in containers, as well as counting the number of toads they encounter and advocating for other protection measures, such as road closures and amphibian passages.

Patrols usually work during the breeding period, when toad crossings are more regular. However, this implies they can overlook groups of young toads, which, having been eggs and then juveniles, leave their water habitats over an irregular timetable in the end of summer. Because of their size – just one or two centimetres wide – "they are destroyed by vehicles." And as being hit "basically turns them into mush," it's harder to collect information on them. At least when adult toads are killed, their remains can be counted.

Year-Round Work

Unlike most patrols, one local team, who are in their eighth season of functioning, go out throughout the year – not nightly, but when conditions are warm and wet, or if a member has posted about a amphibian spotting in their messaging app. When I request to accompany them on duty, they concede it is "not a toady night" – toad hibernation season has begun and it's been a dry day – but several of the helpers gamely agree to patrol their area with me and see what we can find. "If anyone can locate any toads tonight, those two will find one," says the patrol manager, pointing to her 14-year-old son and the experienced member. We've been out for 120 minutes without a glimpse of any amphibians, and now they have climbed over a wire barrier to inspect beneath some logs.

Community Participation

The family duo became part of the patrol a while back. The youngster loves all things nature-related and has an ambition to become a conservationist, so his parent started to search for things they could do jointly to protect native animals. Now she enjoys it as much as he does, the 41-year-old entrepreneur tells me – so when the team was looking for a new manager recently, she decided to step up.

The teenager, too, has been instrumental in the group. A video he created, urging the municipal authority to close a road through a nature reserve during breeding time, influenced the outcome the group's way. After a twelve months of lobbying, the council agreed to an "restricted access" restriction between evening and morning from late winter through to spring. Most drivers respected and avoided the route.

Additional Species 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 see one living newt as well, and the youngster is particularly pleased to see a daddy longlegs, which moves in his hands. Yet in spite of the team's best efforts to let me see a toad, the local population has clearly settled down for the winter. It seems that I couldn't have found any better success elsewhere in the country – all the patrol groups I contact explain that it's near-impossible at this season.

They project rescuing nearly 10,000 grown amphibians during migration

One email I receive from another volunteer, who has kindly taken the trouble to check for toads in a famous site, considered the biggest tracked toad population in the UK, arrives in my inbox with the title: "No toads." However, in February and March, he tells me, the team expects to help around 10,000 mature amphibians over the street.

Impact and Challenges

What level of impact can these organizations actually make? "The fact that people are doing this consistently on chilly, wet and miserable late nights is remarkable," notes an expert. "This effort that very much should be celebrated." However, while rescue teams are able to slow the decline, they cannot prevent it entirely – not least because traffic is just one danger.

Other Dangers

The global warming has meant longer periods of drought, which cause the wrong conditions for some of the creatures that toads consume, such as worms and slugs, while higher water temperatures have caused an rise of blue-green algae, which can be harmful to toads. Milder winters also cause toads to wake up from their hibernation more frequently, interfering with the resource preservation vital to their life cycle. Habitat destruction – particularly 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," but "There is a big value in just having these animals around." But toads do have an significant part in the food chain, consuming almost any invertebrates or small animals they can swallow and in turn sustaining a variety of birds and mammals, such as wildlife. Enhancing conditions for toads – ie building water habitats, protecting forests and constructing toad tunnels – "benefits for a whole bunch of other species."

Cultural Importance

An additional motive to try to keep toads around is their "historical significance," notes an expert. Legends and tales around toads go back {centuries|hundred
