It is a Friday evening at 7:30, but instead of heading to the pub or relaxing at home, I've taken a train to a market town in Wiltshire to meet up with volunteers from a amphibian rescue group. These dedicated individuals sacrifice their nights to protect the local toad population.

An Alarming Decline in Population

The common toad is growing more uncommon. A latest study conducted by an amphibian and reptile charity revealed that the British common toad numbers have dropped by half since 1985. Observing a creature that has been a stalwart of the UK landscape in decrease is labeled "worrying" by researchers. Toads "don't require very specific conditions" and "should be able to live successfully in most of habitats in Britain," so if even they are struggling to persist, "it kind of suggests that the ecosystem is unbalanced."

The Danger from Roads

Though the study didn't examine the reasons for the decline, cars is a major factor. Estimates suggest that 20 tonnes of toads are crushed on British roads every year – that is, hundreds of thousands. Unlike frogs, which might be happy to mate "with just a bucket of water," toads favor big bodies of water. Their capacity to remain away from water for longer than frogs allows they can journey farther to reach them – sometimes long distances. They tend to stick to their ancestral migration routes – it's common for adult toads to go back to their birth pond to mate.

Migration Habits

Appropriately enough, the initial amphibians begin their quest for a partner around February 14th, but others travel as late as spring, waiting until it gets night and travelling through the night. During that time, toads begin migrating from where they have been overwintering "almost simultaneously."

One volunteer, who grew up in the area and has been working to save its toad population since he was a boy, 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 never happen – stopping a next generation of toads from being born.

Toad Patrols Across the United Kingdom

Seeing many of dead toads 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 currently registered with a countrywide program. These groups pick up toads and carry them over streets in buckets, as well as counting the number of toads they find and lobbying for other protection measures, such as blocked roads and underground wildlife tunnels.

Patrols 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 eggs and then juveniles, exit 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 vehicles." And as being hit "basically turns them into mush," it's harder to collect information on them. At least when adult toads are lost, their remains can be tallied.

Annual Work

Unlike many groups, one local team, who are in their eighth season of functioning, go out year-round – not nightly, but when conditions are damp, or if a member has posted about a amphibian spotting in their group chat. When I ask to join them on duty, they admit it is "not a toady night" – winter dormancy has begun and it's been a arid period – but a few of the helpers gamely agree to patrol their area with me and see what we can find. "If anyone can locate 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 two hours without a single toad sighting, and now they have climbed over a barbed wire fence to inspect beneath some wood.

Community Participation

The mother and son became part of the patrol a year and a half ago. The youngster adores all things wildlife and has an ambition to become a environmentalist, so his parent started to search for things they could do together to help native animals. Now she enjoys it as much as he does, the middle-aged small business owner explains – so when the group was seeking a new manager lately, she volunteered for the role.

The youth, too, has played an important role in the organization. A clip he made, urging the municipal authority to close a road through a nature reserve during migration season, swung the decision the team's way. After a year of campaigning, the authority approved an "access-only" restriction between evening and morning from February through to spring. The majority of motorists respected and avoided the route.

Additional Species and Difficulties

Several vehicles go by when I'm out on duty and we discover some casualties as a result – no amphibians, but three squashed newts. We see one living newt as well, and the youngster is particularly pleased to see a harvestman, which dances in his hands. Yet despite the group's best efforts to show me 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 very difficult at this time of year.

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

A message I get from another volunteer, who has kindly taken the trouble to check for toads in a noted location, considered the largest accurately monitored toad group in the UK, reaches me with the subject line: "None found." However, in February and March, he informs me, the group plans to assist around 10,000 mature amphibians across the road.

Impact 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 remarkable," says an expert. "This effort that very much should be celebrated." However, while toad patrols are able to reduce the drop, they cannot prevent it entirely – not least because traffic is just one danger.

Other Dangers

The global warming has meant longer periods of dry weather, which cause the poor environment for some of the animals that toads consume, such as invertebrates, while higher water temperatures have caused an rise of toxic plants, which can be toxic to toads. Milder winters also cause toads to emerge from their hibernation more frequently, disrupting the energy conservation vital to their life cycle. Habitat destruction – particularly the loss of big water bodies – is an additional threat.

Researchers are "often concerned about overemphasizing practical benefits on biodiversity," but "There is a big value in just their presence." But toads do have an significant part in the ecosystem, consuming almost any small creatures or tiny organisms they can fit in their mouths and in turn feeding a number of predators, such as wildlife. Improving situations for toads – such as building water habitats, protecting forests and constructing amphibian passages – "we'll improve them for a wide range of additional wildlife."

Cultural Importance

An additional motive to work to preserve toads around is their "important cultural value," notes an expert. Legends and tales around toads date back {centuries|hundred
