Can Britain's Common Toads Survive from Traffic and Population Collapse?

It's a Friday night at 7:30, but rather than heading to the pub or watching a film, I've caught a train to a market town in the countryside to meet up with local helpers from a amphibian rescue group. These committed people give up their evenings to protect the local toad population.

A Worrying Drop in Numbers

The Bufo bufo is growing more uncommon. A recent research led by an amphibian and reptile charity revealed that the UK toad population have dropped by half since 1985. Seeing a species that has been a stalwart of the UK landscape in decline is described as "worrying" by experts. Toads "don't require very particular environments" and "ought to live quite well in the majority of habitats in Britain," meaning if even they are struggling to persist, "it kind of suggests that things are not as they should be."

Since 1985, Britain's toad numbers have nearly been cut in half

The Threat from Roads

Though the study didn't cover the causes for the drop, cars is a major factor. Estimates indicate that 20 tonnes of toads are killed on UK roads annually – in other words, several hundred thousand. Unlike frogs, which would probably be content to mate "with just a small container," toads favor large ponds. Their capacity to remain away from water for more time than frogs allows they can journey farther to find them – sometimes hundreds of metres. They tend to follow their ancestral migration routes – it's typical for mature amphibians to return to their birth pond to mate.

Breeding Patterns

Appropriately enough, the initial amphibians start their journey for a mate around Valentine's day, but others travel as far as spring, waiting until it gets dark and moving through the night. During that period, toads start moving from wherever they have been overwintering "all pretty much at the same time."

One volunteer, who was raised in the region and has been trying to protect its toad population since he was a boy, notes that "Their sole purpose: to go and mate." If their route crosses a road, they could all get run over, and that mating period would never happen – preventing a new generation of toads from being born.

Rescue Groups Throughout the United Kingdom

Finding hundreds of dead toads on local roads "inherently strikes a chord with people," and has led to the creation of rescue teams across the UK – hundreds of organizations are currently registered with a national initiative. These groups collect toads and transport them over streets in buckets, as well as recording the quantity of toads they find and lobbying for other safety solutions, such as blocked roads and underground wildlife tunnels.

Volunteers usually work during the migration season, when toad crossings are more regular. However, this implies they can overlook groups of young toads, which, having existed as spawn and then juveniles, leave their water habitats over an irregular timetable in the end of summer. Because of their size – just one or two centimetres wide – "they can get obliterated by car traffic." And as being run over "basically turns them into mush," it's more difficult to get data on them. At least when adult toads are lost, their remains can be counted.

Year-Round Efforts

Unlike many groups, a specific volunteer group, who are in their eighth year of operating, go out year-round – not every night, but whenever weather are warm and wet, or if a member has posted about a toad sighting in their group chat. When I request to accompany them on duty, they concede it is "not ideal conditions" – toad hibernation season has begun and it's been a arid period – but a few of the volunteers willingly accept to patrol their route with me and search for any toads. "Should anyone can locate any toads tonight, those two will spot one," says the patrol manager, pointing to her 14-year-old son and the longtime volunteer. After for 120 minutes without a single toad sighting, and now they have climbed over a wire barrier to inspect beneath some logs.

Family Participation

The mother and son joined the group a year and a half ago. The teenager loves all things nature-related and has an goal to become a conservationist, so his parent started to search for things they could do jointly to protect local wildlife. Now she enjoys it as much as he does, the middle-aged small business owner tells me – so when the team was looking for a fresh coordinator recently, she volunteered for the role.

The teenager, too, has been instrumental in the group. A clip 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 February 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 patrol and we find some casualties as a consequence – no toads, but several crushed salamanders. We see one live amphibian as well, and the teenager is especially excited to see a daddy longlegs, which dances in his palms. Yet despite the group's best efforts to let me see a toad, the native community has obviously gone dormant for the winter. It appears that I wouldn't have had any more luck elsewhere in the nation – all the patrol groups I reach out to explain that it's very difficult at this time of year.

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

One email I get from another volunteer, who has generously made the effort to look for toads in a famous site, considered the largest accurately monitored toad population in the UK, reaches me with the title: "None found." However, in late winter, he informs me, the group expects to help approximately ten thousand adult toads over the street.

Effectiveness and Challenges

How much of a difference can these organizations actually make? "The fact that volunteers are performing this consistently on chilly, wet and miserable evenings is quite extraordinary," says an researcher. "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 just one danger.

Other Dangers

The global warming has meant longer periods of drought, which create the wrong conditions for some of the creatures that toads eat, such as worms and slugs, while higher water temperatures have caused an increase of blue-green algae, which can be toxic to toads. Warmer cold seasons also cause toads to wake up from their hibernation more often, interfering with the energy conservation crucial to their life cycle. Habitat destruction – especially the disappearance of big water bodies – is another menace.

Experts are "always a bit worried about putting too much of a utilitarian spin on biodiversity," however "It's important in just their presence." But toads play an important role in the food chain, eating pretty much any small creatures or small animals they can fit in their mouths and in turn feeding a number of birds and mammals, such as hedgehogs and otters. Improving conditions for toads – such as building water habitats, conserving woodland and installing amphibian passages – "we'll improve them for a whole bunch of other species."

Cultural Significance

Another reason to try to keep toads around is their "historical significance," adds an expert. Legends and tales around toads date back {centuries|hundred
