It's a Friday evening at 7:30, but instead of going out or watching a film, I've taken a train to a town in Wiltshire to join volunteers from a toad patrol. These dedicated individuals give up their evenings to safeguard the local toad population.

A Worrying Drop in Numbers

The Bufo bufo is growing more rare. A recent study led by an amphibian and reptile charity showed that the UK toad population have dropped by half since the mid-1980s. Seeing a creature that has been a stalwart of the UK landscape in decrease is labeled "worrying" by researchers. Toads "don't need very particular environments" and "should be able to live quite well in the majority of areas in Britain," so if even they are struggling to persist, "it kind of suggests that things are not as they should be."

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

The Threat from Roads

Though the research didn't examine the causes for the drop, traffic certainly plays a part. Calculations indicate that 20 tons of toads are killed on British roads every year – that is, hundreds of thousands. In contrast to frogs, which might be content to mate "with just a small container," toads favor large ponds. Their capacity to remain away from water for more time than frogs allows they can journey farther to find them – sometimes long distances. They usually stick to their ancestral migration routes – it's common for mature amphibians to go back to their natal pond to mate.

Migration Patterns

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

One volunteer, who was raised in the region and has been working to save its amphibians since he was a child, notes that "They've got just one focus: to go and mate." If their path crosses a road, they could all get run over, and that breeding season would be lost – preventing a next generation of toads from being produced.

Rescue Groups Across the UK

Finding hundreds of dead toads on nearby streets "resonates deeply with people," and has led to the creation of toad patrols throughout the UK – hundreds of organizations are officially listed with a countrywide program. These teams pick up toads and transport them across roads in containers, as well as recording the number of toads they encounter and advocating for other protection measures, such as blocked roads and amphibian passages.

Patrols usually work during the breeding period, when toad crossings are frequent. However, this implies they can miss numbers of young toads, which, having been spawn and then tadpoles, exit their ponds over an irregular timetable in the end of summer. Because of their small stature – just a couple of cm wide – "they can get obliterated by car traffic." And as being hit "basically turns them into mush," it's more difficult to collect information on them. At least when adult toads are killed, their carcasses can be tallied.

Year-Round Work

Unlike most patrols, one local team, who are in their eighth year of operating, go out throughout the year – not nightly, but whenever weather are damp, or if a member has posted about a amphibian spotting in their group chat. When I request to accompany them on patrol, they admit it is "not a toady night" – toad hibernation season has begun and it's been a arid period – but several of the volunteers gamely agree to walk up and down their route with me and search for any toads. "If anyone can locate any toads tonight, those two will spot one," says the patrol manager, pointing to her 14-year-old son and the experienced member. We've been out for two hours without a glimpse of any amphibians, and now they have climbed over a wire barrier to inspect beneath some wood.

Community Participation

The mother and son joined the patrol a year and a half ago. The youngster adores all things wildlife and has an goal to become a environmentalist, so his mother started to search for things they could do together to protect local wildlife. Now she loves it as much as he does, the 41-year-old small business owner tells me – so when the group was looking for a new manager lately, she volunteered for the role.

The youth, too, has been instrumental in the group. A clip he made, urging the local council to block a road through a protected area during breeding time, influenced the outcome the group's way. After a twelve months of campaigning, the council agreed to an "access-only" restriction between evening and morning from February through to April. Most drivers respected and avoided the road.

Additional Species and Difficulties

Several cars go by when I'm out on patrol and we find some victims as a result – no toads, but several crushed salamanders. We see one live amphibian as well, and the youngster is especially excited to see a harvestman, which dances in his hands. Yet despite the group's hardest attempts to show me a toad, the local population has clearly settled down for the winter. It seems that I couldn't have found any better success elsewhere in the country – all the patrol groups I contact clarify 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 made the effort to look for toads in a noted location, thought to be the largest accurately monitored toad population in the UK, reaches me with the subject line: "No toads." However, in late winter, he tells me, the team expects to help approximately 10,000 mature amphibians over the street.

Impact and Challenges

What level of impact can these groups actually make? "The reality that people are performing this regularly on chilly, wet and miserable evenings is quite extraordinary," says an expert. "That's something that very much deserves recognition." However, while rescue teams are able to reduce the drop, they can't stop it completely – partly since traffic is not the only threat.

Other Dangers

The climate crisis has meant longer periods of drought, which cause the wrong conditions for some of the creatures that toads eat, such as worms and slugs, while higher water temperatures have caused an increase of toxic plants, which can be toxic to toads. Milder winters also cause toads to wake up from their hibernation more frequently, interfering with the resource preservation vital to their existence. Loss of environment – particularly the disappearance of large ponds – is another menace.

Researchers are "always a bit worried about putting too much of a utilitarian spin on biodiversity," however "It's important in just having these animals around." But toads play an important role in the food chain, consuming pretty much any invertebrates or tiny organisms they can fit in their mouths and in turn sustaining a number of predators, such as hedgehogs and otters. Enhancing situations for toads – such as creating more ponds, protecting forests and installing amphibian passages – "we'll improve them for a wide range of other species."

Historical Importance

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