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

It's Friday evening at half past seven, but instead of heading to the pub or watching a film, I've taken a train to a town in Wiltshire to meet up with volunteers from a amphibian rescue group. These committed people sacrifice their nights to protect the native amphibian community.

A Worrying Drop in Numbers

The common toad is becoming increasingly uncommon. A latest research conducted by an amphibian and reptile charity revealed that the UK toad population have almost halved since the mid-1980s. Seeing a creature that has been a stalwart of the UK landscape in decline is labeled "concerning" by researchers. Toads "don't need very particular environments" and "should be able to live quite well in most of areas in the UK," so if even they are struggling to persist, "it kind of suggests that the ecosystem is unbalanced."

The Threat from Roads

Though the research didn't cover the causes for the drop, traffic is a major factor. Calculations indicate that 20 tonnes 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 favor big bodies of water. Their capacity to stay out of water for longer than frogs allows they can travel further to reach them – often long distances. They usually follow their ancestral migration routes – it's typical for mature amphibians to go back to their natal pond to mate.

Breeding Patterns

Fittingly, the initial amphibians start their journey for a partner around February 14th, but others travel as far as spring, until it gets night and travelling after sunset. During that period, toads begin migrating from wherever they have been hibernating "all pretty much at the same time."

One volunteer, who grew up in the region and has been working to save its amphibians since he was a boy, explains that "They've got just one focus: to go and mate." If their route crosses a street, they could all get run over, and that mating period would never happen – stopping a next generation of toads from being born.

Rescue Groups Across the United Kingdom

Finding hundreds of dead toads on nearby streets "inherently strikes a chord with people," and has resulted in the formation of toad patrols across the UK – 274 groups are currently registered with a national initiative. These teams collect toads and carry them across roads in containers, as well as counting the number of toads they find and advocating for other protection measures, such as road closures and underground wildlife tunnels.

Volunteers usually work during the migration season, when toad crossings are frequent. However, this implies they can overlook groups of toadlets, which, having existed as spawn and then tadpoles, leave their ponds over an unpredictable schedule in late summer. Because of their size – just one or two centimetres wide – "they can get obliterated 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 killed, their carcasses can be counted.

Annual Work

In contrast to most patrols, one local team, who are in their eighth season of operating, go out year-round – not nightly, but when weather are warm and wet, or if someone has reported about a amphibian spotting in their group chat. When I ask to join them on patrol, they admit it is "not a toady night" – toad hibernation season has started and it's been a dry day – but several of the helpers willingly accept to walk up and down 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, indicating her teenage child and the experienced member. After for two hours without a glimpse of any amphibians, and now they have scaled a wire barrier to inspect beneath some logs.

Family Participation

The mother and son joined the patrol a year and a half ago. The teenager loves all things wildlife and has an ambition to become a environmentalist, so his parent started to look for activities they could do together to protect local wildlife. Now she enjoys it as much as he does, the 41-year-old entrepreneur tells me – so when the team was looking for a fresh coordinator lately, she volunteered for the role.

The youth, too, has been instrumental in the organization. A clip he made, urging the local council to close a street through a protected area during migration season, swung the decision the team's way. After a year of lobbying, the authority agreed to an "access-only" rule between 5pm and 5am from late winter through to April. Most drivers respected and avoided the route.

Additional Species and Difficulties

Several cars go by when I'm out on patrol and we find some victims as a result – no toads, but several crushed salamanders. We see one living newt as well, and the youngster is particularly pleased to see a daddy longlegs, which moves in his palms. Yet in spite of the group's best efforts to show me a toad, the native community has clearly gone dormant for the winter. It appears that I couldn't have found any better success elsewhere in the nation – all the rescue teams I contact explain that it's near-impossible at this time of year.

A message I get from another volunteer, who has generously made the effort to look for toads in a famous site, thought to be the largest accurately monitored toad group in the UK, arrives in my inbox with the subject line: "None found." However, in late winter, he tells me, the group plans to assist approximately ten thousand mature amphibians across the road.

Impact and Limitations

How much of a difference can these groups actually make? "The reality that people are performing this regularly on cold, damp and unpleasant late nights is quite extraordinary," notes an expert. "This effort that very much should be celebrated." However, while rescue teams are able to reduce the drop, they cannot prevent it entirely – not least because vehicles is not the only threat.

Other Dangers

The climate crisis has resulted in longer periods of dry weather, which cause the poor environment for some of the animals that toads consume, such as worms and slugs, while higher water temperatures have caused an increase of toxic plants, which can be toxic to toads. Milder winters also lead toads to wake up from their hibernation more often, disrupting the energy conservation crucial to their existence. Loss of environment – especially the loss of big water bodies – is another menace.

Experts are "often concerned about overemphasizing practical benefits on biodiversity," but "It's important in just having these animals around." But toads play an significant part in the food chain, consuming almost any small creatures or tiny organisms they can fit in their mouths and in turn feeding a number of predators, such as hedgehogs and otters. Improving conditions for toads – ie building water habitats, conserving woodland and constructing amphibian passages – "benefits for a wide range of additional wildlife."

Cultural Significance

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