It's a Friday evening at 7:30, 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 volunteers from a toad patrol. These committed people sacrifice their evenings to safeguard the local toad population.

An Alarming Decline in Population

The Bufo bufo is growing more rare. A latest research led by an amphibian and reptile charity showed that the British common toad numbers have almost halved since 1985. Seeing a creature that has been a stalwart of the UK landscape in decline is labeled "concerning" by researchers. Toads "don't require very specific conditions" and "ought to live quite well in most of habitats in the UK," meaning if even they are struggling to persist, "it kind of suggests that the ecosystem is unbalanced."

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

The Threat from Traffic

Though the study didn't cover the causes for the decline, traffic is a major factor. Calculations indicate that 20 tons of toads are crushed on British roads annually – in other words, hundreds of thousands. Unlike frogs, which might be happy to mate "with just a bucket of water," toads favor big bodies of water. Their ability to remain away from water for more time than frogs means they can journey farther to reach them – often hundreds of metres. They tend to stick to their ancestral migration routes – it's common for mature amphibians to return to their birth pond to mate.

Migration Patterns

Appropriately enough, the initial amphibians begin their quest for a mate around Valentine's day, but some move as far as April, waiting until it gets dark and travelling through the night. During that period, toads begin migrating from wherever they have been overwintering "all pretty much at the same time."

One volunteer, who grew up in the area and has been working to save its toad population since he was a boy, notes that "They've got just one focus: to go and mate." If their path 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 UK

Finding hundreds of toad carcasses on local roads "resonates deeply with people," and has led to the creation of toad patrols across the UK – hundreds of organizations are currently registered with a national initiative. These teams collect toads and transport them across roads in buckets, as well as counting the quantity of toads they find and lobbying for other safety solutions, such as blocked roads and amphibian passages.

Patrols tend to operate during the migration season, when amphibian movements are frequent. However, this means they can miss numbers of toadlets, which, having existed as spawn and then juveniles, exit their water habitats over an irregular timetable in late summer. Because of their size – just a couple of cm wide – "they can get obliterated by car traffic." And as being run over "essentially crushes them," it's harder to get data on them. At least when adult toads are lost, their carcasses can be counted.

Annual Efforts

In contrast to many groups, a specific volunteer group, who are in their eighth season of functioning, go out year-round – not every night, but whenever 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 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 area with me and search for any toads. "If anyone can find any toads tonight, those two will find one," says the group coordinator, indicating her 14-year-old son and the longtime volunteer. After for 120 minutes without a single toad sighting, and now they have scaled a barbed wire fence to inspect beneath some wood.

Family Participation

The family duo joined the patrol a year and a half ago. The youngster loves all things wildlife and has an ambition to become a environmentalist, so his mother started to search for activities they could do together to protect local wildlife. Now she loves it as much as he does, the middle-aged entrepreneur tells me – so when the group was seeking a fresh coordinator lately, she volunteered for the role.

The youth, too, has played an important role in the organization. A clip he made, imploring the local council to block a street through a nature reserve during migration season, influenced the outcome the group's way. After a twelve months of lobbying, the authority approved an "access-only" rule between evening and morning from late winter through to April. Most drivers respected and avoided the route.

Additional Species and Difficulties

A few cars go past when I'm out on duty and we discover some casualties as a consequence – no amphibians, but three squashed newts. We spot one living newt as well, and the teenager is particularly pleased to see a daddy longlegs, which moves in his palms. Yet despite the group's best efforts to show me a toad, the local population has obviously gone dormant for the winter. It seems that I wouldn't have had any better success anywhere else in the nation – all the rescue teams I contact explain that it's near-impossible at this season.

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

A message I receive from a different helper, who has kindly made the effort to check for toads in a famous site, considered the largest accurately monitored toad group in the UK, reaches me with the title: "No toads." However, in late winter, he informs me, the group plans to assist around 10,000 mature amphibians over the street.

Effectiveness and Challenges

How much of a difference can these groups actually make? "The reality that people are performing this consistently on cold, damp and unpleasant evenings is quite extraordinary," notes an expert. "This effort that very much should be celebrated." However, while rescue teams are able to slow the decline, they cannot prevent it entirely – partly since traffic is just one danger.

Other Dangers

The global warming has meant longer periods of dry weather, which create the wrong conditions for some of the creatures that toads eat, such as worms and slugs, while warmer ponds have caused an rise of toxic plants, which can be harmful to toads. Milder winters also lead toads to emerge from their hibernation more often, disrupting the energy conservation vital to their life cycle. Habitat destruction – especially the loss of large ponds – is an additional threat.

Experts are "always a bit worried about overemphasizing practical benefits on wildlife," however "There is a big value in just their presence." But toads do have an significant part in the food chain, eating pretty much any invertebrates or tiny organisms they can fit in their mouths and in turn feeding a variety of predators, such as wildlife. Improving conditions for toads – ie building water habitats, conserving woodland and constructing toad tunnels – "benefits for a whole bunch of other species."

Cultural Significance

An additional motive to try to keep toads present is their "historical significance," adds an expert. Myths and folklore around toads date back {centuries|hundred
