It's Friday evening at 7:30, but instead of going out or watching a film, I've caught a train to a town in Wiltshire to meet up with local helpers from a toad patrol. These dedicated individuals sacrifice their evenings to protect the native amphibian community.

An Alarming Drop in Numbers

The Bufo bufo is growing more rare. A recent research led by an wildlife conservation group revealed that the British common toad numbers have almost halved since 1985. Seeing a creature that has been a stalwart of the UK landscape in decrease is labeled "worrying" by researchers. Toads "don't need very specific conditions" and "ought to live successfully in the majority of habitats in the UK," so if even they are struggling to persist, "it indicates that the ecosystem is unbalanced."

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

The Threat from Traffic

Though the study didn't examine the reasons for the drop, traffic is a major factor. Estimates indicate that 20 tonnes of toads are killed on UK roads annually – that is, several hundred thousand. In contrast to frogs, which would probably be happy 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 means they can journey farther to find them – often hundreds of metres. They usually follow their ancestral migration routes – it's common for adult toads to go back to their natal pond to mate.

Migration Habits

Appropriately enough, the initial amphibians start their journey for a mate around February 14th, but some move as late as spring, until it gets night and travelling after sunset. During that period, toads begin migrating from where they have been overwintering "all pretty much at the same time."

One volunteer, who was raised in the area and has been working to save its toad population since he was a child, notes that "They've got just one focus: to go and mate." If their route happens to a road, they could be killed by traffic, and that mating period would be lost – stopping a next generation of toads from being born.

Rescue Groups Throughout the UK

Finding many of toad carcasses on local roads "inherently strikes a chord with people," and has resulted in the creation of rescue teams across the UK – hundreds of organizations are currently registered with a national initiative. These groups collect toads and carry 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.

Volunteers tend to operate during the breeding period, when amphibian movements are more regular. However, this implies they can miss numbers of toadlets, which, having existed as eggs and then juveniles, leave their water habitats over an unpredictable schedule in the end of summer. Because of their small stature – just a couple of cm wide – "they can get obliterated by car traffic." And as being run over "basically turns them into mush," it's harder to get data on them. At least when mature amphibians are killed, their remains can be counted.

Annual Efforts

In contrast to most patrols, a specific volunteer group, who are in their eighth season of operating, go out throughout the year – not nightly, but whenever weather are warm and wet, or if someone has posted about a toad sighting in their messaging app. When I request to accompany them on duty, they concede it is "not a toady night" – toad hibernation season has started 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. "Should anyone can find any toads tonight, those two will spot one," says the group coordinator, pointing to her 14-year-old son and the experienced member. We've been out for 120 minutes without a glimpse of any amphibians, and now they have climbed over a barbed wire fence to check under some wood.

Family Involvement

The family duo joined the patrol a year and a half ago. The youngster adores all things wildlife and has an goal to become a environmentalist, so his mother started to look for things they could do together 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 fresh coordinator recently, she decided to step up.

The teenager, too, has been instrumental in the organization. A clip he created, imploring the local council to close a street through a nature reserve during migration season, swung the decision the group's way. After a year of campaigning, the council agreed to an "access-only" rule between 5pm and 5am from February through to spring. The majority of motorists duly avoided the route.

Additional Species and Challenges

A few vehicles go by when I'm out on duty and we find some victims as a result – no amphibians, but several crushed salamanders. We see one live amphibian as well, and the youngster is especially excited to see a harvestman, which moves in his hands. Yet despite the team's best efforts to let me see a toad, the local population has clearly gone dormant for the colder months. It appears that I wouldn't have had any better success anywhere else in the country – all the rescue teams I contact explain that it's near-impossible at this season.

They project rescuing nearly 10,000 grown amphibians during migration

A message I get from another volunteer, who has kindly taken the trouble to check for toads in a famous site, considered the largest accurately monitored toad group in the UK, arrives in my inbox with the subject line: "None found." However, in February and March, he informs me, the group expects to help approximately 10,000 mature amphibians across the road.

Impact and Challenges

What level of impact can these groups actually make? "The reality that volunteers are doing this consistently on chilly, wet and miserable late nights is quite extraordinary," notes an researcher. "That's something that very much should be celebrated." However, while rescue teams are able to reduce the drop, they cannot prevent it entirely – partly since vehicles is just one danger.

Other Dangers

The global warming has meant extended spells of dry weather, which cause the poor environment for some of the animals 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 wake up from their hibernation more frequently, disrupting the energy conservation crucial to their life cycle. Loss of environment – especially the disappearance of big water bodies – is an additional threat.

Experts are "often concerned about overemphasizing practical benefits on biodiversity," but "It's important in just having these animals around." But toads do have an important role in the ecosystem, eating almost any invertebrates or tiny organisms they can swallow and in turn sustaining a variety of birds and mammals, such as hedgehogs and otters. Enhancing conditions for toads – such as building water habitats, conserving woodland and installing toad tunnels – "we'll improve them for a wide range of other species."

Historical Importance

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