Will the UK's Common Toads Survive from Roads and Population Collapse?

It is Friday evening at half past seven, but rather than going out or relaxing at home, I've caught a train to a town in Wiltshire to meet up with volunteers from a toad patrol. These committed people sacrifice their evenings to protect the local toad population.

An Alarming Decline in Population

The Bufo bufo is becoming increasingly uncommon. A latest research conducted by an amphibian and reptile charity revealed that the UK toad population have almost halved since 1985. Seeing a creature that has been a fixture of the UK landscape in decline is labeled "worrying" by experts. Toads "don't require very specific conditions" and "should be able to live successfully in the majority of habitats in the UK," meaning if even they are not managing to survive, "it indicates that things are not as they should be."

Since 1985, Britain's toad numbers have nearly been cut in half

The Threat from Traffic

Though the study didn't cover the causes for the drop, cars certainly plays a part. Estimates suggest that 20 tons of toads are killed on British roads every year – in other words, several hundred thousand. In contrast to frogs, which might be content to mate "with just a small container," toads favor large ponds. Their capacity to stay out of water for longer than frogs means they can journey farther to find them – often hundreds of metres. They tend to follow their traditional paths – it's common for adult toads to go back to their natal pond to mate.

Migration Habits

Appropriately enough, the first toads begin their quest for a mate around February 14th, but others travel as far as April, waiting until it gets night and moving through the night. During that period, toads begin migrating from where they have been overwintering "all pretty much at the same time."

A local helper, who was raised in the region and has been working to save its amphibians since he was a boy, notes that "They've got just one focus: to go and mate." If their path crosses a road, they could be killed by traffic, and that mating period would never happen – preventing a new generation of toads from being produced.

Toad Patrols Across the UK

Finding many of toad carcasses on local roads "inherently strikes a chord with people," and has led to the formation of rescue teams throughout the UK – hundreds of organizations are currently registered with a national initiative. These teams collect toads and carry them across roads in buckets, as well as counting the quantity of toads they encounter and lobbying for other protection measures, such as road closures and underground wildlife tunnels.

Patrols tend to operate during the breeding period, when amphibian movements are more regular. However, this means they can overlook groups 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 a couple of cm wide – "they can get obliterated by car traffic." And as being run over "essentially crushes them," it's more difficult to get data on them. At least when mature amphibians are killed, their remains can be tallied.

Annual Efforts

Unlike most patrols, a specific volunteer group, who are in their eighth season of operating, go out throughout the year – not every night, but whenever weather are damp, or if a member has reported about a toad sighting in their group chat. When I request to accompany them on duty, they admit it is "not ideal conditions" – winter dormancy has begun and it's been a dry day – but several of the volunteers willingly accept to patrol their area with me and search for any toads. "If anyone can locate any toads tonight, that pair will find one," says the patrol manager, pointing to her 14-year-old son and the longtime volunteer. After for two hours without a glimpse of any amphibians, and now they have scaled a wire barrier to check under some logs.

Family Participation

The mother and son became part of the group a while back. The teenager adores all things nature-related and has an ambition to become a environmentalist, so his parent started to search for activities they could do jointly to help native animals. Now she enjoys it as much as he does, the 41-year-old entrepreneur explains – so when the team was looking for a fresh coordinator lately, she decided to step up.

The teenager, too, has played an important role in the organization. A clip he created, urging the local council to block a road through a nature reserve during breeding time, influenced the outcome the group's way. After a year of lobbying, the authority agreed to an "access-only" restriction between 5pm and 5am from February through to spring. The majority of motorists respected and avoided the route.

Additional Species and Challenges

Several cars go past when I'm out on patrol and we find some victims 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 dances in his hands. Yet despite the team's hardest attempts to show me a toad, the native community has obviously settled down for the colder months. It seems that I wouldn't have had any more luck elsewhere in the country – all the patrol groups I contact explain that it's very difficult at this season.

They project rescuing nearly 10,000 grown amphibians during migration

A message I get from a different helper, who has kindly taken the trouble to check for toads in a noted location, considered the largest accurately monitored toad group in the UK, arrives in my inbox with the title: "No toads." However, in late winter, he informs me, the team plans to assist approximately 10,000 mature amphibians across the road.

Impact and Challenges

What level of impact can these groups truly achieve? "The fact that people are doing this regularly on cold, damp and unpleasant evenings is remarkable," says an researcher. "This effort that very much deserves recognition." However, while toad patrols are able to slow the decline, they can't stop it completely – not least because vehicles is just one danger.

Additional Threats

The climate crisis has meant longer periods of drought, which cause the poor environment for some of the creatures that toads eat, such as worms and slugs, while higher water temperatures have caused an rise of toxic plants, which can be toxic to toads. Milder winters also cause toads to wake up from their hibernation more frequently, interfering with the energy conservation vital to their existence. Loss of environment – especially the disappearance of large ponds – is another menace.

Experts are "often concerned about putting too much of a utilitarian spin on wildlife," however "There is a big value in just their presence." But toads play an significant part in the food chain, consuming pretty much any small creatures or small animals they can swallow and in turn feeding a variety of birds and mammals, such as hedgehogs and otters. Enhancing situations for toads – such as creating more ponds, conserving woodland and constructing amphibian passages – "we'll improve them for a whole bunch of additional wildlife."

Historical Importance

An additional motive to try to keep toads around is their "historical significance," notes an expert. Legends and tales around toads date back {centuries|hundred
