Can the UK's Common Toads Be Saved from Roads and Population Collapse?

It is Friday night at half past seven, but rather than heading to the pub or watching a film, I've taken a train to a town in the countryside to join local helpers from a toad patrol. These dedicated individuals sacrifice their evenings to safeguard the local toad population.

An Alarming Drop in Population

The common toad is growing more uncommon. A recent study led by an wildlife conservation group showed that the British common toad numbers have almost halved since the mid-1980s. Observing a creature that has been a fixture of the British countryside in decrease is described as "concerning" by experts. Toads "don't need very particular environments" and "ought to live quite well in the majority of areas in the UK," meaning if even they are not managing to survive, "it kind of suggests that things are not as they should be."

The Danger from Roads

Though the research didn't examine the reasons for the decline, traffic is a major factor. Estimates indicate that 20 tonnes of toads are killed on UK roads annually – in other words, hundreds of thousands. Unlike frogs, which might be happy to mate "with just a bucket of water," toads prefer big bodies of water. Their capacity to remain away from water for longer than frogs means they can journey farther to find them – often long distances. They usually stick to their traditional paths – it's typical for adult toads to go back to their natal pond to mate.

Migration Habits

Fittingly, the first toads start their journey for a mate around Valentine's day, but some move as far as spring, waiting until it gets night and travelling after sunset. During that time, toads start moving from where they have been overwintering "almost simultaneously."

One volunteer, who was raised in the region and has been working to save its toad population since he was a child, explains that "Their sole purpose: to go and mate." If their path crosses a street, they could all get run over, and that breeding season would be lost – stopping a new generation of toads from being produced.

Rescue Groups Across the United Kingdom

Finding many of toad carcasses on nearby streets "resonates deeply with people," and has resulted in the creation of toad patrols throughout the UK – 274 groups are officially listed with a countrywide program. These groups pick up toads and transport them across roads in buckets, as well as recording the number of toads they find and advocating for other protection measures, such as blocked roads and amphibian passages.

Volunteers tend to operate during the migration season, when amphibian movements are more regular. However, this implies they can overlook numbers of young toads, which, having been spawn and then juveniles, leave 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 car traffic." And as being hit "basically turns them into mush," it's harder to collect information on them. At least when mature amphibians are killed, their remains can be tallied.

Year-Round Work

Unlike many groups, a specific volunteer group, who are in their eighth season of operating, go out throughout the year – not every night, but when weather are warm and wet, or if a member 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 volunteers willingly accept to walk up and down their area with me and see what we can find. "If anyone can find any toads tonight, that pair will find one," says the group coordinator, indicating her 14-year-old son and the experienced member. After for two hours without a glimpse of any amphibians, and now they have climbed over a wire barrier to inspect beneath some logs.

Community Involvement

The family duo became part of the patrol a year and a half ago. The teenager loves all things nature-related and has an ambition to become a conservationist, so his parent started to look for things they could do jointly to help 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 recently, she volunteered for the role.

The youth, too, has been instrumental in the group. A video he made, urging the municipal authority to close a street through a nature reserve during breeding time, swung the decision the team's way. After a year of campaigning, the council approved an "restricted access" restriction between evening and morning from February through to spring. Most drivers respected and avoided the road.

Other Wildlife and Difficulties

Several vehicles go past when I'm out on duty and we discover some victims as a consequence – no amphibians, but three squashed newts. We see one living newt 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 show me a toad, the local population has clearly gone dormant for the winter. It appears that I couldn't have found any better success anywhere else in the nation – all the rescue teams I reach out to explain that it's very difficult at this season.

This team anticipates assisting around ten thousand mature toads over the street

A message I get from another volunteer, who has generously made the effort to look for toads in a noted location, considered the largest accurately monitored toad population in the UK, reaches me with the title: "None found." However, in February and March, he informs me, the team plans to assist approximately ten thousand mature amphibians across the road.

Effectiveness and Limitations

What level of impact can these organizations actually make? "The fact that people are doing this regularly on chilly, wet and miserable late nights is quite extraordinary," says an researcher. "That's something that very much should be celebrated." However, while toad patrols are able to slow the decline, they cannot prevent it entirely – not least because traffic is just one danger.

Other Dangers

The climate crisis has resulted in longer periods of dry weather, which create the wrong conditions for some of the animals that toads consume, such as invertebrates, while higher water temperatures have caused an rise of blue-green algae, which can be toxic to toads. Warmer cold seasons also lead toads to emerge from their dormancy more frequently, disrupting the energy conservation vital to their life cycle. Loss of environment – particularly the loss of large ponds – is an additional threat.

Experts are "always a bit worried 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, eating pretty much any invertebrates or small animals they can fit in their mouths and in turn sustaining a number of birds and mammals, such as wildlife. Improving situations for toads – such as creating more ponds, conserving woodland and constructing amphibian passages – "we'll improve them for a whole bunch of other species."

Historical Importance

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