It is Friday night at 7:30, but instead of heading to the pub 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 safeguard the local toad population.

A Worrying Drop in Population

The Bufo bufo is growing more uncommon. A recent research led by an amphibian and reptile charity revealed that the UK toad population have dropped by half since 1985. Seeing a species that has been a fixture of the British countryside in decrease is described as "worrying" by experts. Toads "don't require very particular environments" and "should be able to live quite well in most of areas in the UK," meaning if even they are struggling to persist, "it indicates that the ecosystem is unbalanced."

Toad populations across the UK have declined by almost 50% since the 1980s

The Danger from Traffic

Though the study didn't cover the causes for the decline, traffic is a major factor. Estimates indicate that 20 tons of toads are crushed on UK roads every year – in other words, several hundred thousand. In contrast to frogs, which would probably be content to mate "with just a small container," toads favor big bodies of water. Their capacity to stay out of water for more time than frogs means they can journey farther to reach them – sometimes long distances. They tend to stick to their ancestral migration routes – it's common for adult toads to return to their natal pond to mate.

Breeding Habits

Appropriately enough, the initial amphibians start their journey for a mate around February 14th, but some move as far as April, waiting until it gets dark and travelling through the night. During that time, toads start moving from where they have been overwintering "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, explains that "Their sole purpose: to go and have an orgy." If their route happens to a road, they could be killed by traffic, and that mating period would be lost – preventing a new generation of toads from being produced.

Toad Patrols Across the United Kingdom

Finding hundreds of dead toads on nearby streets "resonates deeply with people," and has led to the formation of rescue teams across the UK – hundreds of organizations are currently registered with a countrywide program. These groups pick up toads and transport 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 underground wildlife tunnels.

Volunteers tend to operate during the breeding period, when toad crossings are more regular. However, this implies they can overlook numbers of young toads, which, having been spawn and then tadpoles, exit their ponds over an unpredictable schedule in the end of summer. Because of their size – just a couple of cm wide – "they are destroyed by vehicles." And as being run over "basically turns them into mush," it's harder to get data on them. At least when adult toads are lost, their carcasses can be tallied.

Annual Work

Unlike most patrols, a specific volunteer group, who are in their eighth year of functioning, go out year-round – not nightly, but whenever conditions are warm and wet, or if someone has reported about a amphibian spotting in their messaging app. When I request to accompany them on duty, they admit it is "not a toady night" – toad hibernation season has begun and it's been a arid period – but a few of the helpers willingly accept to patrol their route with me and see what we can find. "If anyone can find any toads tonight, those two will spot one," says the group coordinator, pointing to her 14-year-old son and the experienced member. After for two hours without a glimpse of any amphibians, and now they have scaled a barbed wire fence to check under some wood.

Family Involvement

The family duo became part of the group a year and a half ago. The youngster loves all things nature-related and has an ambition to become a environmentalist, so his parent started to look for activities they could do together to help local wildlife. Now she enjoys it as much as he does, the 41-year-old entrepreneur tells me – so when the group was seeking a new manager lately, she volunteered for the role.

The teenager, too, has been instrumental in the group. A video he created, urging the municipal authority to block a street through a nature reserve during breeding time, influenced the outcome the group's way. After a twelve months of campaigning, the council approved an "restricted access" rule between 5pm and 5am from February through to spring. Most drivers duly avoided the road.

Other Wildlife and Difficulties

Several vehicles go by when I'm out on duty and we find some casualties as a result – no toads, but several crushed salamanders. We see one live amphibian as well, and the youngster is particularly pleased to see a harvestman, which dances in his hands. Yet in spite of the group's best efforts to let me see a toad, the local population has clearly settled down for the winter. It appears that I wouldn't have had any more luck anywhere else in the country – all the rescue teams I contact explain that it's very difficult at this time of year.

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

A message I get from a different helper, who has kindly taken the trouble to look for toads in a famous site, considered the biggest tracked toad population in the UK, reaches me with the title: "No toads." However, in late winter, he tells me, the team plans to assist approximately ten thousand adult toads across the road.

Impact and Challenges

How much of a difference can these groups actually make? "The fact that people 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 resulted in extended spells of drought, which create the wrong conditions for some of the creatures that toads eat, such as invertebrates, while higher water temperatures have caused an increase of blue-green algae, which can be toxic to toads. Milder winters also lead toads to emerge from their dormancy more frequently, interfering with the resource preservation crucial to their existence. Habitat destruction – especially the loss of large ponds – is another menace.

Experts are "always a bit worried about putting too much of a utilitarian spin on biodiversity," but "It's important in just having these animals around." But toads do have an significant part in the ecosystem, eating pretty much any small creatures or small animals they can fit in their mouths and in turn feeding a number of predators, such as wildlife. Improving situations for toads – ie creating more ponds, protecting forests and constructing toad tunnels – "benefits for a whole bunch of other species."

Cultural Importance

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