It's Friday night at half past seven, but instead of going out or relaxing at home, I've taken a train to a market town in the countryside to join volunteers from a amphibian rescue group. These dedicated individuals sacrifice their nights to safeguard the local toad population.

A Worrying Decline in Numbers

The Bufo bufo is growing more uncommon. A latest study led by an wildlife conservation group revealed that the British common toad numbers have almost halved since 1985. Seeing a species that has been a fixture of the UK landscape in decline is labeled "concerning" by experts. Toads "don't need very specific conditions" and "ought to live successfully in the majority of areas in Britain," meaning if even they are not managing to survive, "it kind of suggests that things are not as they should be."

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

The Threat from Traffic

Though the study didn't cover the reasons for the decline, cars certainly plays a part. Estimates indicate that 20 tons of toads are killed on British roads annually – that is, hundreds of thousands. In contrast to frogs, which might be content to mate "if you left out a small container," toads prefer large ponds. Their capacity to remain away from water for more time than frogs allows they can journey farther to find them – often long distances. They usually stick to their ancestral migration routes – it's common for mature amphibians to go back to their natal pond to mate.

Migration Patterns

Fittingly, the first toads begin their quest for a partner around Valentine's day, but others travel as far as spring, waiting until it gets dark and travelling through the night. During that time, toads begin migrating from where they have been overwintering "all pretty much at the same time."

One volunteer, 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 route crosses a road, they could all get run over, and that mating period would never happen – preventing a next generation of toads from being produced.

Toad Patrols Across the United Kingdom

Finding hundreds of toad carcasses on local roads "resonates deeply with people," and has resulted in the creation of toad patrols across the UK – 274 groups are officially listed with a national initiative. These groups collect toads and transport them across roads 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 usually work during the migration season, when amphibian movements are more regular. However, this implies they can overlook numbers of young toads, which, having been spawn and then juveniles, exit their ponds over an unpredictable schedule in late summer. Because of their size – just one or two centimetres wide – "they can get obliterated by car traffic." And as being run over "basically turns them into mush," it's more difficult to collect information on them. At least when adult toads are lost, their carcasses can be counted.

Year-Round Work

Unlike 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 a member has reported about a toad sighting in their messaging app. When I request to accompany them on duty, they admit it is "not ideal conditions" – toad hibernation season has begun and it's been a dry day – but a few of the helpers willingly accept to walk up and down their route with me and see what we can find. "If anyone can locate any toads tonight, that pair will find one," says the patrol manager, pointing to her teenage child and the longtime volunteer. We've been out for 120 minutes without a single toad sighting, and now they have climbed over a barbed wire fence to check under some wood.

Community Participation

The family duo joined the patrol a while back. The youngster loves all things wildlife and has an goal to become a conservationist, so his parent started to search for things they could do jointly to protect native animals. Now she loves 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 volunteered for the role.

The youth, too, has been instrumental in the organization. A clip he created, urging the municipal authority to close a road through a nature reserve during breeding time, influenced the outcome the team's way. After a year of campaigning, the authority approved 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 by when I'm out on duty and we find some casualties as a consequence – no amphibians, but several crushed salamanders. We spot one live amphibian as well, and the youngster is particularly pleased to see a daddy longlegs, which dances in his palms. Yet in spite of the group's best efforts to show me a toad, the native community has obviously gone dormant for the winter. It seems that I couldn't have found any more luck elsewhere in the country – all the patrol groups I reach out to explain that it's near-impossible at this time of year.

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

One email I get from a different helper, who has kindly taken the trouble to check for toads in a noted location, considered the biggest tracked toad group in the UK, reaches me with the title: "None found." However, in February and March, he tells me, the group plans to assist approximately 10,000 mature amphibians across the road.

Impact and Limitations

How much of a difference can these organizations truly achieve? "The reality that people are doing this consistently on chilly, wet and miserable late nights is remarkable," says an expert. "This effort that very much deserves recognition." However, while rescue teams are able to slow the decline, they can't stop it completely – partly since vehicles is not the only threat.

Other Dangers

The global warming has resulted in extended spells of dry weather, which cause the poor environment for some of the creatures that toads consume, such as worms and slugs, while warmer ponds have led to an rise of toxic plants, which can be toxic to toads. Milder winters also cause toads to emerge from their hibernation more often, interfering with the energy conservation vital to their existence. Loss of environment – especially the loss of large ponds – is another menace.

Researchers are "always a bit worried about putting too much of a utilitarian spin on wildlife," but "There is a big value in just their presence." But toads play an important role in the ecosystem, consuming almost any invertebrates or tiny organisms they can swallow and in turn sustaining a variety of predators, such as hedgehogs and otters. Enhancing conditions for toads – ie creating more ponds, conserving woodland and installing amphibian passages – "we'll improve them for a whole bunch of other species."

Historical Significance

Another reason to work to preserve toads around is their "historical significance," notes an specialist. Myths and folklore around toads go back {centuries|hundred
