It's Friday evening at 7:30, but rather than heading to the pub or relaxing at home, I've caught a train to a town in Wiltshire to meet up with local helpers from a toad patrol. These dedicated individuals give up their evenings to protect the native amphibian community.

An Alarming Decline in Numbers

The Bufo bufo is becoming increasingly uncommon. A recent study led by an wildlife conservation group showed that the British common toad numbers have dropped by half since the mid-1980s. Observing a species that has been a fixture of the British countryside in decline is labeled "worrying" by experts. Toads "don't require very particular environments" and "ought to live quite well in most of areas in Britain," so if even they are not managing to survive, "it indicates 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 research didn't examine the reasons for the decline, cars is a major factor. Calculations suggest that 20 tonnes of toads are crushed on UK roads every year – in other words, hundreds of thousands. In contrast to frogs, which might be content to mate "if you left out a small container," toads prefer big bodies of water. Their capacity to stay out of water for longer than frogs means they can journey farther to reach them – sometimes hundreds of metres. They usually stick to their traditional paths – it's typical for mature amphibians to return to their natal pond to mate.

Migration Patterns

Fittingly, the initial amphibians begin their quest for a partner around Valentine's day, but some move as far as spring, until it gets night and travelling after sunset. During that time, toads start moving from where they have been overwintering "almost simultaneously."

One volunteer, who grew up in the area and has been trying to protect its amphibians since he was a child, notes that "Their sole purpose: to go and mate." If their path 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 produced.

Rescue Groups Throughout the UK

Finding many of dead toads on local roads "resonates deeply with people," and has led to the creation of rescue teams throughout the UK – 274 groups are currently registered with a national initiative. These groups pick up toads and transport them across roads in containers, as well as counting the number of toads they encounter and lobbying for other protection measures, such as blocked roads and underground wildlife tunnels.

Patrols tend to operate during the breeding period, when toad crossings are frequent. However, this implies they can overlook numbers of toadlets, which, having existed as eggs and then juveniles, exit their water habitats over an irregular timetable in late summer. Because of their size – just one or two centimetres wide – "they are destroyed by car traffic." And as being run over "essentially crushes them," it's more difficult to get data on them. At least when adult toads are lost, their remains can be counted.

Year-Round Work

In contrast to many groups, a specific volunteer group, who are in their eighth season of operating, go out year-round – not every night, but when weather are warm and wet, or if someone has posted about a toad sighting in their messaging app. When I ask to join 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 patrol their area with me and see what we can find. "If anyone can find any toads tonight, that pair will find one," says the group coordinator, pointing to 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 barbed wire fence to inspect beneath 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 ambition to become a conservationist, so his mother started to search for activities they could do together to help local wildlife. 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 volunteered for the role.

The teenager, too, has been instrumental in the group. A clip he created, imploring the municipal authority to close a street through a protected area during breeding time, swung the decision the group's way. After a twelve months of campaigning, the council agreed to an "restricted access" rule between evening and morning from February through to spring. The majority of motorists respected and avoided the road.

Other Wildlife and Difficulties

Several vehicles go past when I'm out on duty and we find some casualties as a consequence – no amphibians, but three squashed newts. We see one living newt as well, and the youngster is particularly pleased to see a harvestman, which dances in his hands. Yet despite the group's best efforts to show me a toad, the native community has clearly gone dormant for the winter. It appears that I wouldn't have had any more luck elsewhere in the country – all the rescue teams I reach out to clarify that it's near-impossible at this season.

This team anticipates assisting around ten thousand mature toads over the street

One email I get from another volunteer, who has kindly made the effort to look for toads in a famous site, considered the largest accurately monitored toad group in the UK, reaches me with the subject line: "None found." However, in February and March, he informs me, the team plans to assist approximately 10,000 mature amphibians across the road.

Effectiveness and Limitations

How much of a difference can these groups truly achieve? "The reality that people are performing this regularly on chilly, wet and miserable evenings is quite extraordinary," notes an researcher. "This effort that very much deserves recognition." However, while toad patrols are able to slow the decline, they cannot prevent it entirely – not least because traffic is not the only threat.

Additional Threats

The global warming has resulted in longer periods of drought, which create the poor environment for some of the creatures that toads eat, such as invertebrates, while higher water temperatures have led to an increase of blue-green algae, which can be harmful to toads. Warmer cold seasons also cause toads to wake up from their dormancy more often, disrupting the energy conservation crucial to their existence. Habitat destruction – especially the disappearance of large ponds – is another menace.

Researchers are "always a bit worried about putting too much of a utilitarian spin on biodiversity," but "It's important in just their presence." But toads do have an important role in the food chain, eating almost any invertebrates or small animals they can swallow and in turn feeding a number of birds and mammals, such as wildlife. Enhancing conditions for toads – such as building water habitats, conserving woodland and constructing toad tunnels – "we'll improve them for a whole bunch of other species."

Historical Importance

Another reason to try to keep toads around is their "important cultural value," notes an expert. Myths and folklore around toads date back {centuries|hundred
