It is Friday evening at half past seven, but rather than heading to the pub or relaxing at home, I've taken a train to a town in Wiltshire to join volunteers from a amphibian rescue group. These committed people sacrifice 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 wildlife conservation group revealed that the British common toad numbers have almost halved since 1985. Observing a species that has been a fixture of the British countryside in decline is described as "concerning" by experts. Toads "don't need very specific conditions" and "ought to live successfully in most of areas in Britain," so if even they are struggling to persist, "it kind of suggests that the ecosystem is unbalanced."

Toad populations across the UK have declined by almost 50% since the 1980s

The Threat from Traffic

Though the research didn't examine the causes for the drop, traffic certainly plays a part. Estimates suggest that 20 tonnes of toads are crushed on UK roads every year – that is, hundreds of thousands. In contrast to frogs, which would probably be content to mate "with just a bucket of water," toads prefer 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 long distances. They tend to follow their ancestral migration routes – it's typical for adult toads to return to their birth pond to mate.

Migration Patterns

Fittingly, the first toads begin their quest for a partner around Valentine's day, but some move as late as spring, waiting until it gets night and travelling after sunset. 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 child, notes that "Their sole purpose: to go and mate." If their path crosses a road, they could all get run over, and that mating period would never happen – stopping a new generation of toads from being born.

Toad Patrols Across the UK

Finding many of toad carcasses on nearby streets "resonates deeply with people," and has resulted in the creation of rescue teams throughout the UK – hundreds of organizations are officially listed with a countrywide program. These teams pick up 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 road closures and amphibian passages.

Patrols usually work during the breeding period, when amphibian movements are frequent. However, this implies they can miss numbers of young toads, which, having been spawn and then juveniles, exit their ponds over an irregular timetable in late summer. Because of their small stature – just one or two centimetres wide – "they are destroyed by car traffic." And as being hit "essentially crushes them," it's more difficult to collect information on them. At least when mature amphibians are lost, their remains can be tallied.

Year-Round Efforts

Unlike most patrols, a specific volunteer group, who are in their eighth year of operating, go out throughout the year – 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 concede it is "not ideal conditions" – winter dormancy has begun and it's been a dry day – but several of the volunteers gamely agree to walk up and down their area with me and search for any toads. "If anyone can locate any toads tonight, that pair will spot one," says the group coordinator, indicating her 14-year-old son and the experienced member. We've been out for 120 minutes without a glimpse of any amphibians, and now they have scaled a barbed wire fence to inspect beneath some wood.

Community Involvement

The family duo became part of the patrol a while back. The youngster adores all things wildlife and has an ambition to become a conservationist, so his parent started to look for activities they could do together to help local wildlife. Now she loves it as much as he does, the middle-aged small business owner tells me – so when the group was seeking a fresh coordinator recently, she volunteered for the role.

The youth, too, has played an important role in the organization. A clip he made, imploring the municipal authority to close a street through a nature reserve during migration season, swung the decision the group's way. After a year of lobbying, the council agreed to an "access-only" rule between 5pm and 5am from February through to April. The majority of motorists respected and avoided the route.

Other Wildlife and Difficulties

A few vehicles go by when I'm out on duty and we discover some victims as a result – no amphibians, but three squashed newts. We see one live amphibian as well, and the youngster is particularly pleased to see a daddy longlegs, which dances in his hands. Yet in spite of the team's hardest attempts to let me see a toad, the native community has obviously settled down for the colder months. It seems that I couldn't have found any more luck elsewhere in the nation – all the rescue teams I reach out to explain that it's near-impossible at this time of year.

A message I get from another volunteer, who has generously made the effort to look for toads in a famous site, considered the biggest tracked toad population in the UK, reaches me with the title: "No toads." However, in February and March, he informs me, the group expects to help around ten thousand adult toads across the road.

Impact and Limitations

How much of a difference can these groups truly achieve? "The fact that people are performing this regularly on cold, damp and unpleasant evenings is remarkable," says an expert. "This effort that very much should be celebrated." However, while rescue teams are able to reduce the drop, they can't stop it completely – partly since traffic is not the only threat.

Additional Threats

The climate crisis has meant extended spells of drought, which create the poor environment for some of the animals that toads eat, such as invertebrates, while higher water temperatures have led to an rise of blue-green algae, which can be toxic to toads. Milder winters also lead toads to wake up from their dormancy more frequently, disrupting the energy conservation crucial to their existence. Loss of environment – especially the disappearance of big water bodies – is an additional threat.

Experts are "often concerned about putting too much of a utilitarian spin on biodiversity," but "There is a big value in just having these animals around." But toads do have an significant part in the food chain, consuming pretty much any small creatures or tiny organisms they can swallow and in turn sustaining a number of birds and mammals, such as hedgehogs and otters. Improving situations for toads – ie building water habitats, conserving woodland and constructing toad tunnels – "benefits for a whole bunch of other species."

Historical Significance

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