It's Friday night 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 local helpers from a toad patrol. These committed people sacrifice their nights to protect the native amphibian community.

A Worrying Drop in Numbers

The Bufo bufo is growing more uncommon. A recent study conducted by an amphibian and reptile charity revealed that the UK toad population have dropped by half since the mid-1980s. Observing a species that has been a fixture of the British countryside in decline is described as "concerning" by experts. Toads "don't need very specific conditions" and "should be able to live quite well in the majority of habitats in Britain," meaning if even they are not managing to survive, "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 decline, cars certainly plays a part. Calculations suggest that 20 tonnes of toads are killed on British roads annually – that is, hundreds of thousands. Unlike frogs, which might be content to mate "if you left out a small container," toads favor big bodies of water. Their capacity to remain away from water for longer than frogs allows they can journey farther to reach 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.

Breeding Habits

Fittingly, the initial amphibians start their journey for a partner around February 14th, but others travel as far as spring, waiting until it gets dark and travelling through the night. During that period, toads begin migrating from wherever they have been hibernating "all pretty much at the same time."

A local helper, who was raised in the region and has been trying to protect its toad population since he was a child, notes that "They've got just one focus: to go and have an orgy." If their path happens to a road, they could be killed by traffic, and that breeding season would never happen – preventing a next generation of toads from being produced.

Toad Patrols Across the UK

Finding hundreds of dead toads on local roads "inherently strikes a chord with people," and has led to the creation of rescue teams throughout the UK – hundreds of organizations are officially listed with a national initiative. These teams collect toads and transport them over streets in buckets, as well as recording the quantity of toads they find and lobbying for other safety solutions, such as road closures and underground wildlife tunnels.

Patrols tend to operate during the migration season, when amphibian movements are more regular. However, this means they can overlook numbers of toadlets, which, having been eggs and then tadpoles, exit their ponds over an unpredictable schedule in the end of summer. Because of their size – just one or two centimetres 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 mature amphibians are lost, their carcasses can be tallied.

Year-Round Efforts

Unlike many groups, a specific volunteer group, who are in their eighth year of functioning, go out throughout the year – not nightly, but when weather are warm and wet, or if someone has reported about a amphibian spotting in their messaging app. When I ask to join them on patrol, they admit it is "not ideal conditions" – toad hibernation season has started and it's been a arid period – but several of the volunteers gamely agree to patrol their route with me and see what we can find. "If anyone can locate any toads tonight, those two will spot one," says the group coordinator, indicating 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 wire barrier to check under some logs.

Family Participation

The mother and son became part of the group a year and a half ago. The youngster loves all things wildlife and has an goal to become a environmentalist, so his mother started to look for things they could do jointly to help native animals. Now she loves it as much as he does, the middle-aged entrepreneur explains – so when the team was seeking a fresh coordinator recently, she decided to step up.

The teenager, too, has played an important role in the group. A video he created, urging the local council to close a road through a protected area during migration season, swung the decision the group's way. After a twelve months of campaigning, the authority agreed to an "restricted access" rule between 5pm and 5am from February through to spring. The majority of motorists duly avoided the route.

Other Wildlife and Difficulties

Several cars go past when I'm out on patrol 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 especially excited to see a harvestman, which moves in his palms. Yet despite the group's best efforts to let me see a toad, the native community has clearly gone dormant for the colder months. It seems that I couldn't have found any better success elsewhere in the nation – 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 receive from another volunteer, who has kindly made the effort to check for toads in a famous site, considered the biggest tracked toad group in the UK, arrives in my inbox with the subject line: "No toads." However, in late winter, he tells me, the group 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 people are doing this consistently on chilly, wet and miserable late nights is remarkable," says an researcher. "That's something that very much deserves recognition." However, while toad patrols are able to slow the decline, they cannot prevent it entirely – partly since traffic is not the only threat.

Additional Threats

The climate crisis has meant extended spells of dry weather, which cause the wrong conditions for some of the creatures that toads eat, such as invertebrates, while higher water temperatures have caused an rise of toxic plants, which can be harmful to toads. Warmer cold seasons also cause toads to emerge from their hibernation more frequently, disrupting the energy conservation crucial to their life cycle. Habitat destruction – especially the disappearance of large ponds – is another menace.

Researchers are "often concerned about putting too much of a utilitarian spin on biodiversity," but "There is a big value in just their presence." But toads do have an significant part in the ecosystem, eating almost any invertebrates or small animals they can swallow and in turn sustaining a number of predators, such as hedgehogs and otters. Improving situations for toads – such as creating more ponds, protecting forests and constructing toad tunnels – "we'll improve them for a whole bunch of other species."

Cultural Importance

An additional motive to try to keep toads present is their "important cultural value," notes an expert. Myths and folklore around toads go back {centuries|hundred
