It's Friday night at 7:30, but rather than heading to the pub or relaxing at home, I've taken a train to a town in the countryside to join volunteers from a toad patrol. These dedicated individuals sacrifice their nights to protect the native amphibian community.

An Alarming Drop in Population

The Bufo bufo is growing more rare. A recent study conducted by an amphibian and reptile charity showed that the British common toad numbers have almost halved since 1985. Seeing a species that has been a stalwart of the UK landscape in decline is labeled "worrying" by researchers. Toads "don't require very specific conditions" and "should be able to live successfully in most of habitats in the UK," so if even they are struggling to persist, "it indicates that things are not as they should be."

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 decline, cars certainly plays a part. Estimates indicate that 20 tons of toads are killed on British roads annually – in other words, several hundred thousand. In contrast to frogs, which would probably be content to mate "if you left out a small container," toads prefer large ponds. Their capacity to stay out of water for longer than frogs allows they can journey farther to find them – often hundreds of metres. They usually stick to their ancestral migration routes – it's common for adult toads to return to their natal pond to mate.

Migration Patterns

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

One volunteer, who grew up in the area and has been trying to protect its toad population since he was a child, notes that "They've got just one focus: to go and have an orgy." If their route happens to a street, they could all get run over, and that mating period would be lost – preventing a next generation of toads from being born.

Rescue Groups Across the United Kingdom

Finding many of toad carcasses on local roads "resonates deeply with people," and has resulted in the formation of rescue teams across the UK – 274 groups are currently registered with a countrywide program. These teams collect toads and carry them across roads in containers, as well as recording the quantity of toads they encounter and advocating for other protection measures, such as road closures and amphibian passages.

Volunteers usually work during the breeding period, when amphibian movements are more regular. However, this implies they can miss groups of young toads, which, having been eggs and then juveniles, leave their ponds 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 "basically turns them into mush," it's harder to collect information on them. At least when mature amphibians are killed, their remains can be tallied.

Annual Work

Unlike many groups, a specific volunteer group, who are in their eighth year of operating, go out year-round – not every night, but whenever weather are warm and wet, or if someone has posted about a amphibian spotting in their messaging app. When I request to accompany them on duty, they admit it is "not ideal conditions" – toad hibernation season has started and it's been a dry day – but several of the helpers gamely agree to patrol their area with me and see what we can find. "If anyone can find any toads tonight, that pair will spot 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 single toad sighting, and now they have scaled a barbed wire fence to check under some wood.

Community Participation

The mother and son joined the group a while back. The youngster loves all things nature-related and has an ambition to become a conservationist, so his mother started to search for activities they could do together to protect local wildlife. Now she enjoys it as much as he does, the middle-aged small business owner tells me – so when the group was seeking a new manager lately, she decided to step up.

The teenager, too, has played an important role in the group. A video he created, imploring the municipal authority to block a road through a nature reserve during migration season, swung the decision the team's way. After a year of lobbying, the authority agreed to an "restricted access" rule between evening and morning from late winter through to April. Most drivers duly avoided the road.

Additional Species and Challenges

A few 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 live amphibian as well, and the teenager is particularly pleased to see a harvestman, which dances in his palms. Yet in spite of the team's hardest attempts to let me see a toad, the native community has obviously gone dormant for the winter. It seems that I wouldn't have had any better success anywhere else in the nation – all the patrol groups I reach out to explain that it's very difficult at this time of year.

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

A message I receive from a different helper, who has kindly taken the trouble to check for toads in a famous site, considered the biggest tracked toad group in the UK, reaches me with the title: "No toads." However, in late winter, he informs me, the group expects to help approximately 10,000 mature amphibians across the road.

Impact and Challenges

What level of impact can these organizations truly achieve? "The fact that volunteers are performing this consistently on cold, damp and unpleasant evenings is remarkable," notes an expert. "This effort that very much deserves recognition." However, while toad patrols are able to reduce the drop, they can't stop it completely – not least because vehicles is not the only threat.

Other Dangers

The global warming has resulted in longer periods of drought, which create the poor environment for some of the creatures that toads consume, such as invertebrates, while warmer ponds have caused an rise of toxic plants, which can be harmful to toads. Milder winters also cause toads to emerge from their hibernation more frequently, interfering with the resource preservation vital to their existence. Habitat destruction – especially the loss of big water bodies – is another menace.

Researchers are "always a bit worried about overemphasizing practical benefits on biodiversity," however "There is a big value in just having these animals around." But toads play an significant part in the food chain, consuming almost any small creatures or tiny organisms they can swallow and in turn sustaining a number of birds and mammals, such as hedgehogs and otters. Enhancing situations for toads – ie building water habitats, conserving woodland and installing amphibian passages – "we'll improve them for a wide range of other species."

Cultural Importance

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