It's Friday night at half past seven, but instead of going out or watching a film, I've taken a train to a market town in Wiltshire to join local helpers from a toad patrol. These committed people sacrifice their evenings to protect the native amphibian community.

An Alarming Drop in Numbers

The Bufo bufo is growing more rare. A recent research conducted by an wildlife conservation group revealed that the UK toad population have dropped by half since 1985. Observing a species that has been a fixture of the UK landscape in decline is described as "worrying" by experts. Toads "don't need very particular environments" and "ought to live quite well in the majority of habitats in Britain," so if even they are not managing to survive, "it kind of suggests that things are not as they should be."

The Danger from Traffic

Though the research didn't cover the reasons for the drop, traffic certainly plays a part. Calculations suggest that 20 tonnes of toads are killed on UK roads every year – in other words, hundreds of thousands. In contrast to frogs, which would probably be happy to mate "if you left out a small container," toads prefer big bodies of water. Their capacity to remain away from water for longer than frogs allows they can travel further to reach them – often hundreds of metres. They usually follow their traditional paths – it's typical for adult toads to go back to their birth pond to mate.

Migration Habits

Appropriately enough, the initial amphibians start their journey for a partner around February 14th, but others travel as far as spring, waiting until it gets night and travelling through the night. During that period, toads begin migrating from where they have been hibernating "all pretty much at the same time."

A local helper, who was raised in the region and has been trying to protect its amphibians since he was a boy, notes that "Their sole purpose: to go and have an orgy." If their path crosses a road, they could all get run over, and that mating period would be lost – stopping a new generation of toads from being born.

Rescue Groups Throughout the United Kingdom

Finding hundreds of dead toads on local roads "resonates deeply with people," and has resulted in the formation of toad patrols across the UK – 274 groups are currently registered with a national initiative. These teams pick up toads and transport them over streets in containers, as well as recording the number of toads they find and lobbying for other protection measures, such as road closures and underground wildlife tunnels.

Patrols usually work during the migration season, when amphibian movements are more regular. However, this implies they can miss groups of young toads, which, having been eggs and then tadpoles, leave their water habitats over an unpredictable schedule 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 more difficult to collect information on them. At least when adult toads are lost, their remains can be counted.

Annual Efforts

Unlike many groups, a specific volunteer group, who are in their eighth season of functioning, go out throughout the year – not every night, but whenever conditions are warm and wet, or if someone has reported about a amphibian spotting in their group chat. When I ask to join them on patrol, they concede it is "not ideal conditions" – toad hibernation season has begun and it's been a dry day – but several of the helpers gamely agree to patrol their area with me and search for any toads. "Should anyone can locate any toads tonight, that pair will spot one," says the patrol manager, 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 logs.

Family Involvement

The family duo became part of the group a while back. The teenager loves all things nature-related and has an goal to become a environmentalist, so his parent started to search for activities they could do jointly to protect native animals. Now she enjoys it as much as he does, the 41-year-old small business owner explains – so when the group was looking for a fresh coordinator recently, she decided to step up.

The youth, too, has been instrumental in the organization. A video he made, imploring the municipal authority to block a street through a protected area during migration season, influenced the outcome the group's way. After a twelve months of campaigning, the council approved an "access-only" restriction between 5pm and 5am from late winter through to spring. Most drivers respected and avoided the road.

Other Wildlife and Challenges

Several cars go by when I'm out on duty and we find some victims as a result – no toads, but several crushed salamanders. We spot one live amphibian as well, and the youngster is especially excited to see a harvestman, which dances in his hands. Yet in spite of the group's hardest attempts to show me a toad, the local population has clearly gone dormant for the colder months. It appears that I couldn't have found any more luck elsewhere in the country – all the patrol groups I reach out to explain that it's very difficult at this time of year.

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

A message I get from another volunteer, who has generously made the effort to look for toads in a noted location, thought to be the biggest tracked toad group in the UK, arrives in my inbox with the title: "No toads." However, in late winter, he tells me, the group expects to help approximately 10,000 mature amphibians over the street.

Effectiveness and Limitations

What level of impact can these groups actually make? "The reality that people are performing this consistently on chilly, wet and miserable evenings is remarkable," says an expert. "This effort that very much deserves recognition." However, while rescue teams are able to reduce the drop, they can't stop it completely – not least because traffic is just one danger.

Additional Threats

The climate crisis has meant extended spells of drought, which cause the wrong conditions for some of the creatures that toads eat, such as invertebrates, while warmer ponds 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 dormancy more often, disrupting the energy conservation crucial to their existence. Loss of environment – particularly the disappearance of big water bodies – is an additional threat.

Researchers are "often concerned about overemphasizing practical benefits on wildlife," but "It's important in just their presence." But toads play an significant part in the ecosystem, consuming pretty much any invertebrates or tiny organisms they can fit in their mouths and in turn feeding a variety of birds and mammals, such as hedgehogs and otters. Improving conditions for toads – ie building water habitats, conserving woodland and constructing amphibian passages – "we'll improve them for a wide range 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 go back {centuries|hundred
