It's Friday evening at half past seven, but instead of heading to the pub or watching a film, I've caught a train to a market town in Wiltshire to meet up with local helpers from a toad patrol. These dedicated individuals sacrifice their evenings to protect the local toad population.

A Worrying Drop in Population

The common toad is becoming increasingly uncommon. 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 stalwart of the British countryside in decrease is labeled "concerning" by researchers. Toads "don't require very specific conditions" and "ought to live successfully in the majority of habitats in the UK," so if even they are struggling to persist, "it indicates that the ecosystem is unbalanced."

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

The Danger from Traffic

Though the research didn't examine the causes for the drop, traffic is a major factor. Estimates indicate that 20 tons of toads are crushed on UK roads annually – that is, several hundred thousand. Unlike frogs, which might be content to mate "with just a bucket of water," toads prefer large ponds. Their capacity to stay out of water for more time than frogs allows they can journey farther to find them – sometimes long distances. They usually stick to their traditional paths – it's common for mature amphibians to return to their natal pond to mate.

Breeding Patterns

Fittingly, the first toads begin their quest for a mate around Valentine's day, but some move as far as spring, until it gets night and moving through the night. During that period, toads begin migrating from wherever they have been hibernating "all pretty much at the same time."

A local helper, who grew up in the region 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 mate." If their route crosses a street, they could be killed by traffic, and that mating period would never happen – preventing a new generation of toads from being produced.

Toad Patrols Across the UK

Seeing many of toad carcasses on local roads "resonates deeply with people," and has led to the formation of toad patrols across the UK – hundreds of organizations are currently registered with a national initiative. These teams collect toads and carry them over streets in containers, as well as recording the number of toads they encounter and advocating for other protection measures, such as road closures and amphibian passages.

Volunteers tend to operate during the migration season, when amphibian movements are more regular. However, this means they can miss numbers of toadlets, which, having been eggs and then juveniles, exit their water habitats over an irregular timetable in the end of summer. Because of their size – just a couple of cm 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 adult toads are lost, their remains can be counted.

Year-Round Efforts

In contrast to many groups, a specific volunteer group, who are in their eighth year of operating, go out throughout the year – not nightly, but whenever weather 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 ideal conditions" – toad hibernation season has started and it's been a dry day – but a few of the volunteers gamely agree to patrol their route with me and search for any toads. "If anyone can find any toads tonight, that pair will spot one," says the group coordinator, pointing to her 14-year-old son and the experienced member. After for two hours without a single toad sighting, and now they have climbed over a barbed wire fence to inspect beneath some wood.

Community Involvement

The family duo joined the group a while back. The teenager loves all things wildlife and has an ambition to become a conservationist, so his parent started to look for activities they could do jointly to help local wildlife. Now she loves it as much as he does, the 41-year-old small business owner explains – so when the team was looking for a fresh coordinator recently, she decided to step up.

The teenager, too, has been instrumental in the group. A video he made, imploring the municipal authority to block a street through a protected area during breeding time, swung the decision the team's way. After a year of campaigning, the council approved an "access-only" restriction between 5pm and 5am from late winter through to spring. Most drivers duly avoided the route.

Additional Species and Difficulties

Several cars go by when I'm out on duty and we find some casualties as a consequence – no toads, but three squashed newts. We spot one living newt as well, and the teenager is especially excited to see a harvestman, which dances in his palms. Yet in spite of the team's best efforts to let me see a toad, the local population has obviously gone dormant for the colder months. It seems that I wouldn't have had any better success elsewhere in the country – all the rescue teams I contact explain that it's very difficult at this season.

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

A message I receive from a different helper, who has generously made the effort to look for toads in a famous site, thought to be the largest accurately monitored toad population in the UK, arrives in my inbox with the title: "None found." However, in February and March, he informs me, the team plans to assist approximately 10,000 adult toads over the street.

Impact and Limitations

How much of a difference can these organizations truly achieve? "The fact that volunteers are performing this regularly on chilly, wet and miserable late nights is quite extraordinary," notes an researcher. "That's something that very much deserves recognition." However, while toad patrols are able to slow the decline, they can't stop it completely – not least because vehicles is just one danger.

Additional Threats

The climate crisis has meant longer periods of dry weather, which cause 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 toxic to toads. Milder winters also cause toads to emerge from their dormancy more often, interfering with the resource preservation crucial to their existence. Habitat destruction – particularly the loss of large ponds – is an additional threat.

Experts are "always a bit worried about putting too much of a utilitarian spin on biodiversity," however "It's important in just their presence." But toads play an significant part in the food chain, eating pretty much any small creatures or small animals they can fit in their mouths and in turn sustaining a variety of predators, such as wildlife. Improving situations for toads – such as creating more ponds, protecting forests and installing toad tunnels – "we'll improve them for a wide range of other species."

Cultural Significance

Another reason to work to preserve toads present is their "historical significance," adds an expert. Myths and folklore around toads date back {centuries|hundred
