Can Britain's Common Toads Survive from Roads and Terrible Decline?

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 the countryside to meet up with local helpers from a amphibian rescue group. These committed people sacrifice their evenings to safeguard the native amphibian community.

An Alarming Decline in Population

The Bufo bufo is becoming increasingly uncommon. A recent study led by an amphibian and reptile charity revealed that the British common toad numbers have almost halved since the mid-1980s. Seeing a creature that has been a stalwart of the British countryside in decrease is labeled "concerning" by experts. Toads "don't need very particular environments" and "should be able to live successfully in the majority of areas in the UK," meaning 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 Danger from Traffic

Though the study didn't examine the reasons for the decline, cars is a major factor. Calculations suggest that 20 tons of toads are crushed on British roads annually – in other words, hundreds of thousands. In contrast to frogs, which would probably be content to mate "if you left out a small container," toads prefer large ponds. Their ability to stay out of water for more time than frogs allows they can travel further to reach them – often hundreds of metres. They usually stick to their ancestral migration routes – it's common for mature amphibians to go back to their natal pond to mate.

Breeding Patterns

Fittingly, the initial amphibians start their journey for a mate around Valentine's day, but others travel as far as spring, until it gets dark and travelling through the night. During that period, toads begin migrating from wherever they have been hibernating "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 "Their sole purpose: to go and have an orgy." If their route happens to a street, they could be killed by traffic, and that breeding season would be lost – preventing a new generation of toads from being born.

Toad Patrols Across the UK

Finding hundreds of toad carcasses on nearby streets "inherently strikes a chord with people," and has resulted in the formation of rescue teams across the UK – 274 groups are currently registered with a countrywide program. These teams pick up toads and transport them over streets in containers, as well as counting the quantity of toads they encounter and advocating for other protection measures, such as road closures and underground wildlife tunnels.

Patrols tend to operate during the breeding period, when toad crossings are more regular. However, this means they can miss groups of young toads, which, having been spawn and then juveniles, exit their water habitats over an irregular timetable in late summer. Because of their size – just a couple of cm wide – "they are destroyed by car traffic." And as being hit "essentially crushes them," it's more difficult to get data on them. At least when mature amphibians are lost, their carcasses can be counted.

Annual Work

Unlike most patrols, one local team, who are in their eighth season of operating, go out year-round – not every night, but whenever conditions are damp, or if a member has posted about a amphibian spotting in their messaging app. When I request to accompany them on patrol, they concede it is "not ideal conditions" – toad hibernation season has started and it's been a dry day – but a few of the volunteers gamely agree to patrol their route with me and search for any toads. "If anyone can locate any toads tonight, those two will spot one," says the patrol manager, 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 wire barrier to check under some logs.

Community 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 look for things they could do together to protect local wildlife. Now she enjoys it as much as he does, the middle-aged small business owner tells me – so when the team was seeking a new manager lately, she volunteered for the role.

The youth, too, has played an important role in the organization. A clip he created, urging the local council to block a street through a protected area during breeding time, swung the decision the team's way. After a twelve months of campaigning, the authority agreed to an "restricted access" restriction between 5pm and 5am from late winter through to spring. Most drivers duly avoided the route.

Other Wildlife and Difficulties

A few cars go past when I'm out on duty and we discover some casualties as a result – no amphibians, but several crushed salamanders. We spot one live amphibian as well, and the teenager is particularly pleased to see a harvestman, which dances in his palms. Yet despite the group's best efforts to let me see a toad, the local population has clearly settled down for the winter. It seems that I couldn't have found any more luck anywhere else in the country – all the rescue teams I contact clarify that it's very difficult at this time of year.

The group expects to help approximately 10,000 adult toads across the road

One email I get from another volunteer, who has kindly taken the trouble to check for toads in a noted location, considered the biggest tracked toad group in the UK, arrives in my inbox with the subject line: "None found." However, in late winter, he tells me, the team plans to assist approximately ten thousand mature amphibians over the street.

Impact and Challenges

What level of impact can these groups actually make? "The reality that people are performing this consistently on chilly, wet and miserable evenings is quite extraordinary," notes an expert. "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 traffic is just one danger.

Other Dangers

The climate crisis has resulted in extended spells of dry weather, which create the poor environment for some of the creatures that toads consume, such as worms and slugs, while warmer ponds have led to an increase of blue-green algae, which can be harmful to toads. Warmer cold seasons also cause toads to emerge from their hibernation more often, interfering with the resource preservation crucial to their existence. Habitat destruction – particularly the disappearance of large ponds – is an additional threat.

Experts are "often concerned about putting too much of a utilitarian spin on biodiversity," however "It's important in just having these animals around." 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 sustaining a variety of birds and mammals, such as wildlife. Improving situations for toads – such as building water habitats, protecting forests and installing toad tunnels – "benefits for a whole bunch of other species."

Historical Importance

Another reason to work to preserve toads around is their "historical significance," adds an specialist. Legends and tales around toads date back {centuries|hundred
