It's a Friday evening at half past seven, but instead of going out or relaxing at home, I've caught a train to a town in Wiltshire to meet up with volunteers from a toad patrol. These committed people sacrifice their nights to safeguard the native amphibian community.

A Worrying Drop in Numbers

The Bufo bufo is growing more uncommon. A latest study conducted by an amphibian and reptile charity showed that the British common toad numbers have almost halved since 1985. Observing a species that has been a fixture of the UK landscape in decrease is labeled "concerning" by researchers. Toads "don't need very particular environments" and "ought to live successfully in the majority of habitats in Britain," so if even they are struggling to persist, "it kind of suggests that things are not as they should be."

Since 1985, Britain's toad numbers have nearly been cut in half

The Threat from Roads

Though the research didn't examine the reasons for the decline, traffic is a major factor. Estimates indicate that 20 tons of toads are crushed on UK roads annually – that is, several hundred thousand. Unlike frogs, which might be content to mate "with just a small container," toads favor big bodies of water. Their ability to remain away from water for longer than frogs allows they can travel further to reach them – often hundreds of metres. They tend to follow their traditional paths – it's common for mature amphibians to return to their natal pond to mate.

Breeding Habits

Fittingly, the first toads begin their quest for a mate around Valentine's day, but others travel as far as April, until it gets dark and travelling after sunset. During that period, toads start moving from wherever they have been hibernating "almost simultaneously."

One volunteer, who grew up in the region and has been working to save its amphibians since he was a boy, notes 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 next generation of toads from being produced.

Rescue Groups Throughout the United Kingdom

Finding many of dead toads on local roads "resonates deeply with people," and has led to the creation of toad patrols across the UK – hundreds of organizations are officially listed with a national initiative. These groups collect toads and transport them over streets in buckets, as well as counting the number of toads they find and advocating for other protection measures, such as road closures and underground wildlife tunnels.

Patrols usually work during the breeding period, when toad crossings are frequent. However, this implies they can overlook groups of young toads, which, having existed as spawn and then juveniles, exit their water habitats over an unpredictable schedule in late summer. Because of their size – just one or two centimetres wide – "they are destroyed by vehicles." And as being run over "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.

Annual Work

Unlike most patrols, one local team, who are in their eighth year of operating, go out throughout the year – not every night, but whenever conditions are warm and wet, or if a member has reported about a amphibian spotting in their group chat. When I request to accompany them on patrol, they concede it is "not ideal conditions" – toad hibernation season has begun and it's been a arid period – but several of the volunteers gamely agree to walk up and down their area with me and search for any toads. "If anyone can locate any toads tonight, that pair will find one," says the patrol manager, pointing to her 14-year-old son and the longtime volunteer. We've been out for two hours without a glimpse of any amphibians, and now they have climbed over a wire barrier to check under some logs.

Community Participation

The family duo joined the patrol a year and a half ago. The teenager loves all things nature-related and has an goal to become a conservationist, so his mother started to look for things they could do jointly to help native animals. Now she enjoys it as much as he does, the middle-aged entrepreneur tells me – so when the group was seeking a new manager lately, she volunteered for the role.

The teenager, too, has played an important role in the organization. A video he created, imploring the municipal authority to close 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 "restricted access" restriction between evening and morning from late winter through to spring. Most drivers respected and avoided the route.

Additional Species and Difficulties

A few vehicles go past when I'm out on duty and we discover some victims as a consequence – no amphibians, but several crushed salamanders. We see one live amphibian as well, and the youngster is especially excited to see a daddy longlegs, which moves in his hands. Yet despite the group'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 better success elsewhere in the nation – all the rescue teams I contact explain that it's very difficult at this time of year.

The group expects to help approximately 10,000 adult toads across the road

One email I receive from a different helper, who has kindly taken the trouble to check for toads in a noted location, thought to be the largest accurately monitored toad population in the UK, reaches me with the title: "No toads." However, in February and March, he tells me, the group plans to assist around ten thousand adult toads across the road.

Effectiveness and Challenges

How much of a difference can these organizations truly achieve? "The reality that volunteers are doing this regularly on chilly, wet and miserable evenings is remarkable," notes an expert. "That's something that very much deserves recognition." However, while toad patrols are able to reduce the drop, they can't stop it completely – partly since vehicles is not the only threat.

Other Dangers

The climate crisis has resulted in extended spells of drought, which cause the wrong conditions for some of the animals 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 emerge from their hibernation more often, interfering with the resource preservation vital to their existence. Habitat destruction – particularly the disappearance of big water bodies – is an additional threat.

Experts are "often concerned about overemphasizing practical benefits on biodiversity," however "It's important in just their presence." But toads do have an important role in the ecosystem, consuming almost any small creatures or small animals they can swallow and in turn feeding a variety of predators, such as hedgehogs and otters. Enhancing situations for toads – ie creating more ponds, conserving woodland and constructing amphibian passages – "we'll improve them for a whole bunch of additional wildlife."

Historical Significance

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