It is Friday night at half past seven, but rather than going out or watching a film, I've taken a train to a town in Wiltshire to meet up with local helpers from a toad patrol. These dedicated individuals give up their nights to safeguard the local toad population.

An Alarming Decline in Numbers

The common toad is becoming increasingly rare. A recent study conducted by an amphibian and reptile charity revealed that the British common toad numbers have dropped by half since the mid-1980s. Seeing a species that has been a fixture of the UK landscape in decline is described as "concerning" by researchers. Toads "don't need very particular environments" and "should be able to live successfully in the majority of areas in the UK," so if even they are struggling to persist, "it indicates that things are not as they should be."

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

The Danger from Traffic

Though the research didn't cover the causes for the decline, traffic is a major factor. Calculations indicate that 20 tonnes of toads are killed on British roads annually – that is, hundreds of thousands. Unlike 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 allows 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 natal pond to mate.

Migration Patterns

Fittingly, the initial amphibians begin their quest for a partner around Valentine's day, but others travel as far as April, waiting until it gets night and moving after sunset. During that time, toads start moving from wherever they have been hibernating "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 child, explains that "They've got just one focus: to go and have an orgy." If their route crosses a street, they could be killed by traffic, and that breeding season would never happen – stopping a next generation of toads from being produced.

Toad Patrols Across the UK

Seeing hundreds of dead toads on nearby streets "resonates deeply with people," and has resulted in the formation of rescue teams throughout the UK – 274 groups are officially listed with a national initiative. These groups collect toads and transport them across roads in containers, as well as recording the number of toads they find and advocating for other protection measures, such as road closures and underground wildlife tunnels.

Volunteers tend to operate during the migration season, when toad crossings are frequent. However, this means they can miss groups of young toads, which, having existed as spawn and then juveniles, leave their ponds over an unpredictable schedule 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 get data on them. At least when mature amphibians are killed, their remains can be tallied.

Annual Efforts

In contrast to most patrols, one local team, who are in their eighth year of operating, go out year-round – not nightly, but whenever conditions are damp, or if someone has reported about a amphibian spotting in their messaging app. When I request to accompany them on patrol, they concede it is "not a toady night" – toad hibernation season has started and it's been a dry day – but a few of the helpers willingly accept to walk up and down their area with me and search for any toads. "If anyone can find any toads tonight, those two will find one," says the patrol manager, pointing to her 14-year-old son and the longtime volunteer. We've been out for two hours without a glimpse of any amphibians, and now they have climbed over a wire barrier to check under some logs.

Community Participation

The family duo joined the patrol a while back. The youngster loves all things nature-related and has an ambition to become a conservationist, so his mother started to look for things they could do jointly to protect 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 seeking a new manager recently, she decided to step up.

The teenager, too, has been instrumental in the group. A video he made, imploring the municipal authority to close a road through a protected area during breeding time, swung the decision the team's way. After a year of campaigning, the council approved an "restricted access" restriction between 5pm and 5am from February through to April. The majority of motorists respected and avoided the route.

Other Wildlife and Challenges

A few vehicles go by when I'm out on duty and we find some victims as a consequence – no toads, but several crushed salamanders. We see one live amphibian as well, and the teenager is especially excited 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 gone dormant for the winter. It appears that I couldn't have found any more luck anywhere else in the nation – all the rescue teams I contact clarify that it's very difficult at this season.

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

A message I get from another volunteer, who has generously taken the trouble to check 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 February and March, he informs me, the team expects to help around ten thousand mature amphibians over the street.

Effectiveness and Limitations

How much of a difference can these groups truly achieve? "The reality that people are performing this regularly on cold, damp and unpleasant late nights is remarkable," notes an researcher. "That's something that very much deserves recognition." However, while toad patrols are able to reduce the drop, they cannot prevent it entirely – not least because vehicles is just one danger.

Other Dangers

The climate crisis has resulted in extended spells of drought, which create the poor environment for some of the animals that toads consume, such as worms and slugs, while higher water temperatures have caused an increase of blue-green algae, which can be harmful to toads. Milder winters also lead toads to wake up from their dormancy more frequently, interfering with the resource preservation crucial to their life cycle. Habitat destruction – especially the disappearance of big water bodies – is another menace.

Experts are "often concerned about overemphasizing practical benefits on biodiversity," but "It's important in just having these animals around." But toads do have an important role in the ecosystem, eating almost any invertebrates or small animals they can fit in their mouths and in turn feeding a number of predators, such as hedgehogs and otters. Enhancing situations for toads – such as creating more ponds, conserving woodland and constructing amphibian passages – "we'll improve them for a wide range of additional wildlife."

Historical Importance

An additional motive to try to keep toads present is their "important cultural value," notes an specialist. Myths and folklore around toads date back {centuries|hundred
