Can the UK's Toads Survive from Traffic and Terrible Decline?

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 meet up with local helpers from a amphibian rescue group. These dedicated individuals give up their evenings to protect the local toad population.

A Worrying Drop in Numbers

The common toad is growing more uncommon. A latest research conducted by an wildlife conservation group revealed that the UK toad population have dropped by half since the mid-1980s. Seeing a species that has been a fixture of the British countryside in decline is labeled "worrying" by researchers. Toads "don't need very specific conditions" and "ought to live quite well in the majority of areas in Britain," meaning if even they are not managing to survive, "it indicates that the ecosystem is unbalanced."

The Danger from Roads

Though the research didn't examine the reasons for the drop, cars is a major factor. Estimates indicate that 20 tonnes of toads are killed on British roads annually – that is, several hundred thousand. In contrast to frogs, which might be happy to mate "with just a small container," toads prefer big bodies of water. Their ability to remain away from water for longer than frogs means they can journey farther to reach them – sometimes long distances. They usually follow their ancestral migration routes – it's common for adult toads to return to their birth pond to mate.

Breeding Habits

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

One volunteer, who grew up in the area and has been trying to protect its toad population since he was a child, explains that "They've got just one focus: to go and mate." If their route happens to a road, they could be killed by traffic, and that mating period would never happen – stopping a next generation of toads from being born.

Toad Patrols Throughout the United Kingdom

Finding many of toad carcasses on local roads "inherently strikes a chord with people," and has led to the formation of rescue teams throughout the UK – hundreds of organizations are officially listed with a national initiative. These groups collect toads and transport them over streets in buckets, as well as recording the quantity of toads they encounter and advocating for other protection measures, such as blocked roads and underground wildlife tunnels.

Volunteers tend to operate during the migration season, when toad crossings are more regular. However, this implies they can overlook numbers of young toads, which, having existed as spawn and then juveniles, leave their ponds over an irregular timetable in the end of summer. Because of their small stature – just one or two centimetres wide – "they can get obliterated by car traffic." And as being run over "essentially crushes them," it's harder to collect information on them. At least when adult toads are killed, their carcasses can be counted.

Annual Work

Unlike many groups, one local team, who are in their eighth year of functioning, go out throughout the year – not nightly, but when conditions are warm and wet, or if a member has reported about a amphibian spotting in their group chat. When I ask to join them on patrol, they admit it is "not ideal conditions" – winter dormancy has started and it's been a dry day – but a few of the volunteers willingly accept to patrol their route with me and search for any toads. "If anyone can locate any toads tonight, that pair will spot one," says the patrol manager, indicating her teenage child and the experienced member. After for two hours without a glimpse of any amphibians, and now they have scaled a barbed wire fence to check under some wood.

Community Involvement

The mother and son became part of the group a year and a half ago. The youngster loves all things wildlife and has an ambition to become a conservationist, so his parent started to look for things they could do together to help native animals. Now she enjoys it as much as he does, the middle-aged entrepreneur tells me – so when the group was looking for a fresh coordinator lately, she decided to step up.

The teenager, too, has been instrumental in the organization. A video he made, imploring 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 authority approved an "restricted access" rule between evening and morning from late winter through to spring. The majority of motorists duly avoided the route.

Additional Species and Difficulties

A few vehicles go past when I'm out on duty and we find some victims as a consequence – no amphibians, but several crushed salamanders. We see one living newt as well, and the teenager is especially excited to see a harvestman, which dances in his palms. Yet despite the team's hardest attempts to let me see a toad, the native community has obviously gone dormant for the colder months. It appears that I wouldn't have had any better success elsewhere in the country – all the patrol groups I reach out to clarify that it's near-impossible at this season.

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

A message I receive from another volunteer, who has generously taken the trouble to check for toads in a famous site, considered the largest accurately monitored toad population in the UK, arrives in my inbox with the subject line: "No toads." However, in late winter, he tells me, the group plans to assist around 10,000 mature amphibians across the road.

Impact and Limitations

How much of a difference can these groups actually make? "The reality that volunteers are performing this regularly on chilly, wet and miserable late nights is quite extraordinary," says an expert. "That's something that very much should be celebrated." However, while rescue teams are able to slow the decline, they cannot prevent it entirely – not least because vehicles is just one danger.

Additional Threats

The climate crisis has resulted in extended spells of dry weather, which create the wrong conditions for some of the creatures that toads consume, such as invertebrates, while higher water temperatures have led to an increase of toxic plants, which can be toxic to toads. Milder winters also lead toads to wake up from their dormancy more frequently, disrupting the resource preservation crucial to their life cycle. Loss of environment – especially the disappearance of big water bodies – is an additional threat.

Researchers are "always a bit worried about putting too much of a utilitarian spin on biodiversity," but "There is a big value in just their presence." But toads play an important role in the food chain, consuming almost any small creatures or small animals they can swallow and in turn feeding a variety of predators, such as hedgehogs and otters. Enhancing situations for toads – ie creating more ponds, protecting forests and installing amphibian passages – "we'll improve them for a whole bunch of other species."

Cultural Significance

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