It's Friday night at 7:30, but instead of going out or watching a film, I've taken a train to a town in the countryside to meet up with volunteers from a amphibian rescue group. These dedicated individuals give up their evenings to protect the native amphibian community.

An Alarming Drop in Numbers

The common toad is becoming increasingly rare. A latest study conducted by an amphibian and reptile charity revealed that the British common toad numbers have almost halved since 1985. Seeing a species that has been a stalwart of the UK landscape in decrease is described as "concerning" by experts. Toads "don't need very particular environments" and "should be able to live quite well in the majority of habitats in Britain," so if even they are struggling to persist, "it kind of suggests that the ecosystem is unbalanced."

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

The Danger from Traffic

Though the study didn't cover the causes for the decline, traffic certainly plays a part. Estimates indicate that 20 tonnes of toads are killed on UK roads every year – in other words, hundreds of thousands. In contrast to frogs, which would probably be happy 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 allows they can journey farther to find them – sometimes long distances. They usually follow their ancestral migration routes – 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 Valentine's day, but others travel as late as April, waiting until it gets night and travelling after sunset. During that time, toads begin migrating from where they have been hibernating "almost simultaneously."

One volunteer, who was raised in the region and has been trying to protect its toad population since he was a child, explains that "Their sole purpose: to go and mate." If their route crosses a street, they could be killed by traffic, and that mating period would be lost – preventing a new generation of toads from being born.

Toad Patrols Throughout the UK

Seeing many of toad carcasses on local roads "resonates deeply with people," and has resulted in the formation of rescue teams throughout the UK – 274 groups are currently registered with a national initiative. These teams collect toads and carry them over streets in containers, as well as recording the number of toads they encounter and advocating for other safety solutions, such as road closures and amphibian passages.

Patrols tend to operate during the migration season, when toad crossings are frequent. However, this means they can overlook numbers of young toads, which, having existed as eggs and then tadpoles, leave their water habitats over an unpredictable schedule in late summer. Because of their size – just one or two centimetres wide – "they can get obliterated by vehicles." And as being hit "basically turns them into mush," it's harder to collect information on them. At least when mature amphibians are killed, their remains can be tallied.

Year-Round Efforts

Unlike most patrols, one local team, who are in their eighth year of functioning, go out year-round – not nightly, but whenever 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 patrol, they concede it is "not a toady night" – toad hibernation season has begun and it's been a arid period – 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, those two will spot one," says the group coordinator, 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 scaled a barbed wire fence to inspect beneath some wood.

Community Involvement

The mother and son became part of the group a year and a half ago. The teenager loves all things nature-related and has an goal to become a environmentalist, so his mother started to search for things they could do together to protect local wildlife. Now she enjoys 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 made, imploring the local council to block a street through a protected area during migration season, swung the decision the team's way. After a year of campaigning, the authority approved an "restricted access" rule between evening and morning from February through to April. Most drivers respected and avoided the road.

Additional Species and Challenges

Several cars go by when I'm out on duty and we discover some casualties as a consequence – no amphibians, but several crushed salamanders. We spot one live amphibian as well, and the teenager is particularly pleased to see a daddy longlegs, which moves in his palms. Yet in spite of the team's hardest attempts to let me see a toad, the local population has clearly gone dormant for the winter. It appears that I wouldn't have had any better success elsewhere in the country – all the rescue teams I reach out to clarify that it's very difficult at this season.

They project rescuing nearly 10,000 grown amphibians during migration

A message I receive from a different helper, who has generously taken the trouble to check for toads in a famous site, thought to be the largest accurately monitored toad population in the UK, arrives in my inbox with the title: "None found." However, in February and March, he tells me, the team plans to assist around 10,000 mature amphibians over the street.

Impact and Limitations

What level of impact can these groups actually make? "The fact that volunteers are doing this regularly on chilly, wet and miserable late nights is quite extraordinary," says an expert. "That's something that very much should be celebrated." However, while toad patrols are able to reduce the drop, they can't stop it completely – partly since traffic is just one danger.

Other Dangers

The global warming has meant longer periods of drought, which create the poor environment for some of the animals 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 lead toads to wake up from their hibernation more often, interfering with the resource preservation vital to their life cycle. Loss of environment – especially the disappearance of big water bodies – is another menace.

Experts are "often concerned about overemphasizing practical benefits on wildlife," but "It's important in just their presence." But toads play an important role in the ecosystem, eating pretty much any small creatures or small animals they can fit in their mouths and in turn sustaining a variety of predators, such as wildlife. Enhancing conditions for toads – such as building water habitats, conserving woodland and installing toad tunnels – "benefits for a wide range of other species."

Historical Significance

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