Can the UK's Toads Survive from Traffic and Population Collapse?

It's Friday evening at 7:30, but rather than going out or relaxing at home, I've caught a train to a town in Wiltshire to join volunteers from a amphibian rescue group. These dedicated individuals give up their evenings to safeguard the native amphibian community.

An Alarming Drop in Numbers

The common toad is becoming increasingly rare. A latest research led by an amphibian and reptile charity revealed that the British common toad numbers have dropped by half since the mid-1980s. Seeing a creature that has been a stalwart of the UK landscape in decrease is described as "concerning" by researchers. Toads "don't need very particular environments" and "ought to live successfully in the majority of habitats in the UK," so if even they are struggling to persist, "it indicates that things are not as they should be."

The Threat from Roads

Though the study didn't examine the reasons for the drop, traffic is a major factor. Estimates indicate that 20 tons of toads are killed on British roads every year – in other words, several hundred thousand. In contrast to frogs, which would probably be happy to mate "with just a small container," toads prefer big bodies of water. Their capacity to remain away from water for longer than frogs allows they can journey farther to find them – sometimes long distances. They tend to stick to their ancestral migration routes – it's typical for mature amphibians to return to their natal pond to mate.

Breeding Patterns

Appropriately enough, the first toads 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 start moving from where they have been overwintering "all pretty much at the same time."

One volunteer, who grew up in the area and has been working to save its toad population since he was a child, explains that "Their sole purpose: to go and have an orgy." If their path crosses a street, they could be killed by traffic, and that mating period would never happen – stopping a next generation of toads from being born.

Rescue Groups Across the United Kingdom

Seeing hundreds of toad carcasses on local roads "inherently strikes a chord with people," and has led to the creation of toad patrols throughout the UK – 274 groups are officially listed with a national initiative. These groups pick up toads and carry them over streets in containers, as well as counting the quantity of toads they find and advocating for other protection measures, such as road closures and amphibian passages.

Volunteers usually work during the breeding period, when amphibian movements are more regular. However, this implies they can overlook groups of toadlets, which, having been spawn and then tadpoles, exit their ponds over an irregular timetable in the end of summer. Because of their size – just a couple of cm wide – "they can get obliterated by vehicles." And as being run over "essentially crushes them," it's more difficult to get data on them. At least when adult toads are killed, their remains can be tallied.

Year-Round Efforts

Unlike most patrols, one local team, who are in their eighth year of operating, go out throughout the year – not nightly, but when conditions 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 admit it is "not a toady night" – toad hibernation season has started and it's been a dry day – but a few of the volunteers willingly accept to walk up and down their area with me and search for any toads. "If anyone can find any toads tonight, those two will spot one," says the patrol manager, pointing to her 14-year-old son and the experienced member. After for two hours without a single toad sighting, and now they have scaled a barbed wire fence to check under some wood.

Family Participation

The mother and son joined the patrol a year and a half ago. The youngster loves all things nature-related and has an goal to become a environmentalist, so his mother started to search for activities they could do jointly to help native animals. Now she loves it as much as he does, the 41-year-old small business owner tells me – so when the group was looking for a fresh coordinator lately, she volunteered for the role.

The teenager, too, has been instrumental in the organization. A clip he made, imploring the local council to close a street through a nature reserve during migration season, influenced the outcome the group's way. After a year of campaigning, the authority agreed to an "restricted access" restriction between evening and morning from late winter through to April. The majority of motorists duly avoided the road.

Additional Species and Difficulties

Several cars go by when I'm out on patrol and we discover some casualties as a result – no amphibians, but three squashed newts. We see one live amphibian as well, and the youngster is particularly pleased to see a daddy longlegs, which moves in his palms. Yet despite the team's best efforts to show me a toad, the native community has clearly settled down for the winter. It appears that I couldn't have found any more luck anywhere else in the nation – all the rescue teams I contact clarify that it's very difficult at this season.

One email I get from a different helper, who has generously taken the trouble to look for toads in a famous site, thought to be the biggest tracked toad group in the UK, arrives in my inbox with the title: "No toads." However, in February and March, he informs me, the team expects to help approximately 10,000 mature amphibians over the street.

Effectiveness and Challenges

What level of impact can these organizations actually make? "The fact that people are performing this consistently on chilly, wet and miserable late nights is remarkable," notes an expert. "This effort that very much should be celebrated." However, while rescue teams are able to slow the decline, they cannot prevent it entirely – partly since 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 animals that toads eat, such as worms and slugs, while higher water temperatures have caused an increase of toxic plants, which can be toxic to toads. Warmer cold seasons also lead toads to wake up from their dormancy more frequently, interfering with the energy conservation vital to their existence. Loss of environment – especially the disappearance of big water bodies – is another menace.

Researchers are "often concerned about putting too much of a utilitarian spin on wildlife," however "There is a big value in just having these animals around." But toads play an significant part in the food chain, eating pretty much any small creatures or tiny organisms they can fit in their mouths and in turn feeding a variety of birds and mammals, such as wildlife. Improving situations for toads – such as building water habitats, protecting forests and constructing amphibian passages – "we'll improve them for a whole bunch of other species."

Cultural Importance

An additional motive to work to preserve toads present is their "important cultural value," adds an specialist. Myths and folklore around toads date back {centuries|hundred
