It is a Friday evening at half past seven, but rather than going out or watching a film, I've caught a train to a town in Wiltshire to meet up with local helpers from a amphibian rescue group. These committed people sacrifice their evenings to protect the local toad population.

An Alarming Decline in Population

The common toad is becoming increasingly uncommon. A latest study conducted by an amphibian and reptile charity revealed that the British common toad numbers have almost halved since 1985. Seeing a creature that has been a stalwart of the British countryside in decline is labeled "worrying" by experts. Toads "don't need very particular environments" and "should be able to live quite well in the majority 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 research didn't examine the causes for the decline, traffic certainly plays a part. Estimates suggest that 20 tonnes of toads are crushed on British roads every year – in other words, hundreds of thousands. Unlike frogs, which would probably be content to mate "if you left out a bucket of water," toads favor large ponds. Their ability to remain away from water for longer than frogs allows they can journey farther to reach them – sometimes long distances. They usually stick to their traditional paths – it's typical for adult toads to return to their natal pond to mate.

Migration Patterns

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

One volunteer, who grew up in the region 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 breeding season would never happen – preventing a next generation of toads from being born.

Toad Patrols Across the UK

Finding many of toad carcasses on local roads "resonates deeply with people," and has resulted in the creation of rescue teams throughout the UK – hundreds of organizations are currently registered with a national initiative. These groups pick up toads and transport them across roads in buckets, as well as recording the quantity of toads they find and lobbying for other safety solutions, such as road closures and underground wildlife tunnels.

Patrols tend to operate during the migration season, when amphibian movements are more regular. However, this implies they can miss numbers of young toads, which, having existed as eggs and then tadpoles, leave their water habitats over an irregular timetable in late summer. Because of their size – just one or two centimetres wide – "they are destroyed by vehicles." And as being run over "essentially crushes them," it's harder to collect information on them. At least when mature amphibians are killed, their carcasses can be counted.

Annual Work

Unlike most patrols, one local team, who are in their eighth year of operating, go out year-round – not nightly, but whenever weather are damp, or if a member has reported about a toad sighting in their group chat. When I ask to join them on patrol, they admit it is "not a toady night" – toad hibernation season has started and it's been a dry day – but a few of the helpers gamely agree to walk up and down their route with me and search for any toads. "If anyone can locate any toads tonight, that pair will find one," says the group coordinator, pointing to her teenage child and the experienced member. We've been out for two hours without a single toad sighting, and now they have climbed over a wire barrier to check under some wood.

Family Involvement

The family duo joined the patrol a year and a half ago. The teenager adores all things wildlife and has an ambition to become a environmentalist, so his mother started to search for activities they could do jointly to help native animals. Now she enjoys it as much as he does, the 41-year-old small business owner tells me – so when the team was looking for a new manager recently, she volunteered for the role.

The teenager, too, has been instrumental in the group. A video he created, imploring the municipal authority to block a road through a protected area during migration season, influenced the outcome the group's way. After a twelve months of campaigning, the council agreed to an "restricted access" rule between 5pm and 5am from February through to spring. Most drivers respected and avoided the route.

Other Wildlife and Challenges

Several vehicles go past when I'm out on duty and we find some casualties as a result – no amphibians, but three squashed newts. We see one living newt as well, and the teenager is particularly pleased to see a daddy longlegs, which dances in his hands. Yet in spite of the team's hardest attempts to show me a toad, the local population has clearly settled down for the colder months. It appears that I couldn't have found any more luck elsewhere in the country – all the rescue teams I contact explain that it's near-impossible at this time of year.

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

One email I get from another volunteer, who has generously made the effort to look for toads in a noted location, considered the biggest tracked toad group in the UK, arrives in my inbox with the subject line: "None found." However, in February and March, he tells me, the group plans to assist around ten thousand mature amphibians over the street.

Impact and Limitations

What level of impact can these groups actually make? "The fact that volunteers 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 toad patrols are able to reduce the drop, they can't stop it completely – not least because vehicles is just one danger.

Other Dangers

The climate crisis has meant extended spells 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 increase of toxic plants, which can be harmful to toads. Warmer cold seasons also cause toads to wake up from their dormancy more frequently, disrupting the energy conservation crucial to their existence. Loss of environment – especially the disappearance of large ponds – is an additional threat.

Experts are "often concerned about putting too much of a utilitarian spin on biodiversity," however "There is a big value in just their presence." But toads do have an important role in the ecosystem, eating almost any small creatures or tiny organisms they can fit in their mouths and in turn feeding a number of birds and mammals, such as wildlife. Enhancing conditions for toads – ie creating more ponds, conserving woodland and constructing amphibian passages – "benefits for a wide range of additional wildlife."

Cultural Significance

Another reason to try to keep toads around is their "historical significance," adds an specialist. Myths and folklore around toads go back {centuries|hundred
