It is a Friday night at 7:30, but instead of heading to the pub or relaxing at home, I've caught a train to a town in Wiltshire to join local helpers from a toad patrol. These dedicated individuals sacrifice their evenings to safeguard the native amphibian community.

An Alarming Decline in Population

The Bufo bufo is becoming increasingly uncommon. A latest study conducted by an amphibian and reptile charity showed that the British common toad numbers have almost halved since the mid-1980s. Seeing a creature that has been a fixture of the British countryside in decline is described as "worrying" by experts. Toads "don't need very specific conditions" and "should be able to live quite well in most of habitats in the UK," meaning if even they are struggling to persist, "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 Danger from Roads

Though the research didn't examine the causes for the decline, cars certainly plays a part. Estimates suggest that 20 tonnes of toads are crushed on British roads annually – in other words, several hundred thousand. In contrast to frogs, which would probably 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 means they can travel further to find them – often hundreds of metres. They usually stick to their ancestral migration routes – it's common for mature amphibians to return to their natal pond to mate.

Breeding Patterns

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

One volunteer, who was raised in the area and has been trying to protect its amphibians since he was a child, explains that "They've got just one focus: to go and mate." If their route crosses a road, they could all get run over, and that breeding season would never happen – stopping a next generation of toads from being produced.

Toad Patrols Throughout the UK

Seeing many of toad carcasses on nearby streets "inherently strikes a chord with people," and has resulted in the creation of rescue teams throughout the UK – hundreds of organizations are officially listed with a national initiative. These groups collect toads and carry them over streets in containers, as well as recording the quantity of toads they encounter and lobbying for other safety solutions, such as blocked roads and underground wildlife tunnels.

Patrols tend to operate during the migration season, when amphibian movements are frequent. However, this means they can miss numbers of young toads, which, having been spawn and then juveniles, exit their water habitats over an unpredictable schedule in the end of summer. Because of their small stature – 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 tallied.

Annual Efforts

In contrast to most patrols, a specific volunteer group, who are in their eighth season of functioning, go out throughout the year – not every night, 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 patrol, they concede it is "not a toady night" – toad hibernation season has begun and it's been a dry day – but a few of the helpers willingly accept to patrol their route with me and search for any toads. "If anyone can locate any toads tonight, those two will find one," says the group coordinator, pointing to her teenage child and the experienced member. After for two hours without a single toad sighting, and now they have climbed over a barbed wire fence to check under some logs.

Family Involvement

The mother and son became part of the patrol a while back. The youngster adores all things wildlife and has an goal to become a conservationist, so his mother started to look for activities they could do together to protect native animals. Now she enjoys it as much as he does, the 41-year-old small business owner explains – so when the group was looking for a new manager recently, she decided to step up.

The youth, too, has been instrumental in the group. A clip he created, imploring the municipal authority to block a street through a nature reserve during migration season, swung the decision the group's way. After a year of lobbying, the authority approved an "access-only" rule between evening and morning from February through to spring. Most drivers duly avoided the route.

Additional Species and Difficulties

A few vehicles go past when I'm out on patrol and we discover some victims as a result – no amphibians, but several crushed salamanders. We spot one living newt as well, and the youngster is particularly pleased to see a harvestman, which dances in his hands. Yet in spite of the team's hardest attempts to let me see a toad, the native community has clearly gone dormant for the winter. It seems that I couldn't have found any better success anywhere else in the nation – all the patrol groups I contact clarify that it's very difficult at this season.

They project rescuing nearly 10,000 grown amphibians during migration

One email I get from a different helper, who has generously taken the trouble to check for toads in a famous site, thought to be the biggest tracked toad population in the UK, reaches me with the title: "None found." However, in late winter, he informs me, the group expects to help approximately 10,000 adult toads over the street.

Effectiveness and Limitations

What level of impact can these organizations truly achieve? "The reality that people are doing this regularly on cold, damp and unpleasant late nights is remarkable," says an researcher. "That's something that very much should be celebrated." However, while rescue teams are able to reduce the drop, they can't stop it completely – not least because traffic is just one danger.

Other Dangers

The climate crisis has resulted in extended spells of drought, which create the wrong conditions for some of the creatures that toads eat, such as invertebrates, while warmer ponds have led to an increase of blue-green algae, which can be toxic to toads. Warmer cold seasons also cause toads to emerge from their dormancy more frequently, disrupting the energy conservation crucial to their life cycle. Habitat destruction – particularly the loss of large ponds – is another menace.

Researchers are "often concerned about putting too much of a utilitarian spin on wildlife," but "There is a big value in just their presence." 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 predators, such as hedgehogs and otters. Improving situations for toads – such as creating more ponds, conserving woodland and constructing amphibian passages – "benefits for a whole bunch of additional wildlife."

Historical Significance

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