Will Britain's Toads Survive from Traffic and Population Collapse?

It's Friday evening at 7:30, but rather than heading to the pub or relaxing at home, I've caught a train to a market town in Wiltshire to join volunteers from a amphibian rescue group. These committed people give up their nights to safeguard the native amphibian community.

A Worrying Decline in Population

The common toad is becoming increasingly rare. A recent study conducted 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 described as "concerning" by researchers. Toads "don't need very particular environments" and "should be able to live quite well in the majority 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 study didn't cover the reasons for the decline, cars is a major factor. Calculations suggest that 20 tonnes of toads are killed on British roads annually – that is, hundreds of thousands. Unlike frogs, which might be content to mate "with just a small container," toads prefer large ponds. Their capacity to remain away from water for longer than frogs allows they can journey farther to find them – sometimes hundreds of metres. They tend to follow their traditional paths – it's common for mature amphibians to go back to their natal pond to mate.

Breeding Habits

Fittingly, the first toads start their journey for a partner around Valentine's day, but some move as late as April, waiting until it gets dark and moving through the night. During that time, toads begin migrating from wherever they have been overwintering "all pretty much at the same time."

A local helper, who was raised in the area and has been working to save its amphibians since he was a boy, explains that "Their sole purpose: to go and mate." If their path crosses a road, they could all get run over, and that breeding season would be lost – preventing a next generation of toads from being produced.

Toad Patrols Throughout the UK

Seeing hundreds of toad carcasses on nearby streets "inherently strikes a chord with people," and has led to the creation of rescue teams throughout the UK – 274 groups are currently registered with a national initiative. These groups collect toads and carry them across roads in containers, as well as recording 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 amphibian movements are frequent. However, this implies they can miss groups of young toads, which, having existed as eggs and then juveniles, exit their water habitats over an irregular timetable in late summer. Because of their small stature – just one or two centimetres wide – "they can get obliterated by vehicles." And as being hit "essentially crushes them," it's more difficult to get data on them. At least when adult toads are lost, their carcasses can be counted.

Annual Work

Unlike many groups, a specific volunteer group, who are in their eighth year of operating, go out year-round – not every night, but whenever conditions are damp, or if someone has reported about a amphibian spotting in their group chat. When I request to accompany them on duty, they concede it is "not a toady night" – toad hibernation season has started and it's been a arid period – but several of the helpers gamely agree to walk up and down their route with me and search for any toads. "Should anyone can find any toads tonight, that pair will find one," says the group coordinator, pointing to her 14-year-old son and the longtime volunteer. We've been out for 120 minutes without a glimpse of any amphibians, and now they have climbed over a wire barrier to check under some logs.

Community Participation

The family duo became part of the group a year and a half ago. The youngster adores all things nature-related and has an ambition to become a conservationist, so his mother started to search for activities they could do together to help local wildlife. Now she loves it as much as he does, the middle-aged small business owner tells me – so when the group was seeking a new manager recently, she volunteered for the role.

The teenager, too, has been instrumental in the group. A clip he made, urging the local council to close a road through a nature reserve during breeding time, swung the decision the group's way. After a year of lobbying, the council agreed to an "access-only" restriction between evening and morning from late winter through to April. The majority of motorists duly avoided the road.

Additional Species and Difficulties

A few cars go past when I'm out on duty and we discover some victims as a result – no toads, but several crushed salamanders. We spot one living newt as well, and the youngster is particularly pleased to see a daddy longlegs, which dances in his palms. Yet in spite of the group's hardest attempts to show me a toad, the local population has obviously 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 reach out to clarify that it's very difficult at this time of year.

They project rescuing nearly 10,000 grown amphibians during migration

A message I receive from another volunteer, who has kindly taken the trouble to check for toads in a noted location, thought to be the largest accurately monitored toad group in the UK, arrives in my inbox with the subject line: "No toads." However, in late winter, he informs me, the team plans to assist around 10,000 mature amphibians across the road.

Impact and Limitations

How much of a difference can these organizations actually make? "The fact that volunteers are performing this regularly on cold, damp and unpleasant late nights is remarkable," says an expert. "This effort that very much deserves recognition." However, while rescue teams are able to reduce the drop, they cannot prevent it entirely – partly since traffic is not the only threat.

Additional Threats

The climate crisis has meant longer periods of drought, which cause the poor environment for some of the animals that toads eat, such as invertebrates, while higher water temperatures have led to an increase of toxic plants, which can be harmful to toads. Milder winters also cause toads to wake up from their hibernation more often, interfering with the resource preservation crucial to their existence. Habitat destruction – particularly the disappearance of big water bodies – is another menace.

Experts are "often concerned about overemphasizing practical benefits on wildlife," but "It's important in just their presence." But toads do have 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. Enhancing conditions for toads – such as building water habitats, conserving woodland and constructing amphibian passages – "benefits for a whole bunch of additional wildlife."

Historical Importance

Another reason to try to keep toads around is their "important cultural value," notes an specialist. Legends and tales around toads date back {centuries|hundred
