It's Friday night at half past seven, but rather than heading to the pub or relaxing at home, 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 nights to protect the native amphibian community.

An Alarming Drop in Numbers

The Bufo bufo 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 species that has been a stalwart of the UK landscape in decrease is labeled "worrying" by experts. Toads "don't require very particular environments" and "should be able to live quite well in most of areas in Britain," so if even they are not managing to survive, "it kind of suggests that the ecosystem is unbalanced."

Toad populations across the UK have declined by almost 50% since the 1980s

The Threat from Traffic

Though the research didn't examine the causes for the drop, traffic is a major factor. Estimates suggest that 20 tons of toads are killed on British roads annually – that is, hundreds of thousands. In contrast to frogs, which might be happy 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 allows they can journey farther to find them – sometimes long distances. They tend to stick to their ancestral migration routes – it's typical for mature amphibians to go back to their natal pond to mate.

Breeding Patterns

Appropriately enough, the first toads begin their quest for a mate around February 14th, but others travel as late as April, until it gets night and travelling through the night. During that period, toads start moving from where they have been overwintering "all pretty much at the same time."

A local helper, who was raised in the region 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 route happens to a street, they could all get run over, and that mating period would be lost – stopping a next generation of toads from being born.

Toad Patrols Throughout the UK

Finding hundreds of dead toads on nearby streets "inherently strikes a chord with people," and has resulted in the formation of toad patrols across the UK – 274 groups are officially listed with a national initiative. These teams 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.

Volunteers usually work during the breeding period, when amphibian movements are more regular. However, this implies they can overlook numbers of toadlets, which, having existed as eggs and then tadpoles, leave their water habitats over an unpredictable schedule in the end of summer. Because of their size – just one or two centimetres wide – "they can get obliterated by vehicles." And as being run over "essentially crushes them," it's more difficult to get data on them. At least when mature amphibians are lost, their carcasses can be counted.

Annual Work

In contrast to most patrols, a specific volunteer group, who are in their eighth season of functioning, go out throughout the year – not nightly, but whenever weather are damp, or if someone has reported about a toad sighting in their messaging app. When I request to accompany them on patrol, they admit it is "not a toady night" – toad hibernation season has begun and it's been a dry day – but several of the volunteers gamely agree to walk up and down their route with me and see what we can find. "If anyone can find any toads tonight, that pair will find one," says the group coordinator, indicating her teenage child and the experienced member. After for two hours without a glimpse of any amphibians, and now they have climbed over a barbed wire fence to check under some logs.

Community Participation

The mother and son joined the group a year and a half ago. The teenager adores all things wildlife and has an goal to become a conservationist, so his mother started to look for activities 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 group was seeking a fresh coordinator recently, she volunteered for the role.

The youth, too, has played an important role in the group. A video he created, imploring the local council to block a street through a nature reserve during migration season, swung the decision the group's way. After a year of lobbying, the council approved an "access-only" rule between 5pm and 5am from February through to April. The majority of motorists respected and avoided the route.

Other Wildlife and Difficulties

A few cars go past when I'm out on duty and we discover some casualties as a result – no amphibians, but three squashed newts. We see one living newt as well, and the teenager is particularly pleased to see a harvestman, which dances in his hands. Yet despite the team's hardest attempts to show me a toad, the native community has obviously gone dormant for the colder months. It seems that I couldn't have found any more luck elsewhere in the country – all the rescue teams I contact clarify that it's near-impossible at this season.

One email I get from a different helper, who has generously made the effort to look for toads in a noted location, thought to be the biggest tracked toad population in the UK, reaches me with the subject line: "No toads." However, in late winter, he informs me, the team plans to assist approximately ten thousand adult toads over the street.

Impact and Challenges

How much of a difference can these organizations truly achieve? "The fact that volunteers are doing this consistently on cold, damp and unpleasant late nights is quite extraordinary," notes an researcher. "This effort that very much deserves recognition." However, while rescue teams are able to reduce the drop, they cannot prevent it entirely – partly since vehicles is not the only threat.

Other Dangers

The global warming has meant longer periods of drought, which cause the wrong conditions 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. Warmer cold seasons also lead toads to emerge from their hibernation more frequently, disrupting the resource preservation vital to their existence. Loss of environment – especially the loss of large ponds – is an additional threat.

Experts are "always a bit worried about overemphasizing practical benefits on biodiversity," but "There is a big value in just having these animals around." But toads play an important role in the food chain, eating pretty much any invertebrates or tiny organisms they can swallow and in turn feeding a number of birds and mammals, such as hedgehogs and otters. Improving situations for toads – such as building water habitats, protecting forests and installing toad tunnels – "we'll improve them for a whole bunch of other species."

Historical Importance

Another reason to try to keep toads present is their "historical significance," adds an expert. Legends and tales around toads date back {centuries|hundred
