It is Friday evening at half past seven, but rather than going out or relaxing at home, I've taken a train to a town in Wiltshire to join volunteers from a toad patrol. These dedicated individuals sacrifice their evenings to safeguard the local toad population.

A Worrying Decline in Numbers

The Bufo bufo is becoming increasingly uncommon. A latest research conducted by an wildlife conservation group revealed that the British common toad numbers have almost halved since the mid-1980s. Seeing a species that has been a stalwart of the UK landscape in decrease is labeled "concerning" by experts. Toads "don't require very particular environments" and "ought to live successfully in the majority of areas in the UK," meaning if even they are struggling to persist, "it kind of suggests that things are not as they should be."

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

The Threat from Roads

Though the research didn't cover the reasons for the drop, cars certainly plays a part. Estimates indicate that 20 tons of toads are killed on British roads annually – in other words, 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 stay out of water for longer than frogs means they can travel further to reach them – often long distances. They usually follow their traditional paths – it's common for mature amphibians to go back to their natal pond to mate.

Breeding Habits

Appropriately enough, the first toads begin their quest for a partner around Valentine's day, but others travel as far as April, until it gets dark and travelling after sunset. During that period, toads begin migrating from where they have been overwintering "almost simultaneously."

A local helper, who grew up in the area and has been working to save its amphibians since he was a boy, 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 breeding season would be lost – preventing a new generation of toads from being born.

Toad Patrols Across the United Kingdom

Finding many of toad carcasses on nearby streets "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 buckets, as well as recording the number of toads they encounter and advocating for other protection measures, such as blocked roads and underground wildlife tunnels.

Volunteers usually work during the migration season, when amphibian movements are frequent. However, this means they can overlook numbers of toadlets, which, having been eggs and then tadpoles, exit their water habitats over an irregular timetable in the end of summer. Because of their small stature – just one or two centimetres wide – "they can get obliterated by car traffic." And as being run over "essentially crushes them," it's more difficult to collect information on them. At least when mature amphibians are killed, their remains can be tallied.

Year-Round Efforts

Unlike most patrols, a specific volunteer group, who are in their eighth year of functioning, go out throughout the year – not nightly, but when weather are damp, or if a member has posted about a amphibian spotting in their group chat. When I request to accompany them on duty, they concede it is "not a toady night" – toad hibernation season has begun 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, those two will spot one," says the group coordinator, indicating her teenage child and the experienced member. We've been out for two hours without a glimpse of any amphibians, and now they have scaled a barbed wire fence to inspect beneath some logs.

Family Participation

The family duo became part of the group a year and a half ago. The youngster adores all things wildlife and has an ambition to become a environmentalist, so his parent started to search for things they could do together 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 seeking a new manager lately, she volunteered for the role.

The teenager, too, has been instrumental in the group. A clip he made, imploring the municipal authority to close a street through a protected area during breeding time, swung the decision the team's way. After a year of lobbying, the council agreed to an "restricted access" restriction between evening and morning from late winter through to April. Most drivers respected and avoided the route.

Additional Species and Challenges

Several cars go by when I'm out on patrol and we find some victims as a consequence – no amphibians, but several crushed salamanders. We see one living newt as well, and the teenager is especially excited to see a daddy longlegs, which dances in his hands. Yet in spite of the group's best efforts to show me a toad, the local population has clearly settled down for the colder months. It seems that I couldn't have found any better success elsewhere in the country – all the patrol groups I reach out to explain that it's near-impossible at this time of year.

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

A message I receive from another volunteer, who has kindly made the effort to check for toads in a famous site, considered the largest accurately monitored toad group in the UK, arrives in my inbox with the title: "None found." However, in late winter, he tells me, the group expects to help approximately ten thousand adult toads over the street.

Effectiveness and Challenges

What level of impact can these organizations truly achieve? "The reality that people are doing this consistently on cold, damp and unpleasant evenings is remarkable," notes an researcher. "This effort that very much should be celebrated." However, while rescue teams are able to slow the decline, they cannot prevent it entirely – partly since traffic is just one danger.

Additional Threats

The climate crisis has meant extended spells of drought, which cause the poor environment for some of the creatures that toads consume, such as worms and slugs, while warmer ponds have caused an rise of blue-green algae, which can be harmful to toads. Warmer cold seasons also lead toads to emerge from their dormancy more frequently, interfering with the energy conservation crucial to their existence. Habitat destruction – especially the disappearance of large ponds – is another menace.

Researchers are "often concerned about overemphasizing practical benefits on wildlife," but "It's important in just having these animals around." But toads do have an important role in the ecosystem, consuming pretty much any small creatures or tiny organisms they can swallow and in turn feeding a number of birds and mammals, such as hedgehogs and otters. Enhancing conditions for toads – ie building water habitats, protecting forests and installing amphibian passages – "we'll improve them for a whole bunch of additional wildlife."

Cultural Importance

An additional motive to work to preserve toads present is their "historical significance," adds an specialist. Myths and folklore around toads go back {centuries|hundred
