It is a Friday evening at 7:30, but rather than going out or watching a film, I've taken a train to a town in Wiltshire to meet up with volunteers from a toad patrol. These committed people give up their evenings to safeguard the local toad population.

An Alarming Drop in Numbers

The Bufo bufo is becoming increasingly rare. A recent research led by an wildlife conservation group revealed that the UK toad population have dropped by half since the mid-1980s. Observing a species that has been a fixture of the UK landscape in decrease is labeled "concerning" by researchers. Toads "don't need very particular environments" and "ought to live quite well in most of areas in the UK," so if even they are not managing to survive, "it indicates that the ecosystem is unbalanced."

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

The Threat from Roads

Though the study didn't cover the causes for the drop, cars certainly plays a part. Estimates suggest that 20 tons of toads are killed on UK roads annually – that is, several hundred thousand. Unlike frogs, which might be happy to mate "if you left out a bucket of water," toads prefer big bodies of water. Their ability to remain away from water for more time than frogs means they can journey farther to reach them – often hundreds of metres. They tend to stick to their ancestral migration routes – it's common for adult toads to go back to their natal pond to mate.

Migration Habits

Appropriately enough, the first toads start their journey for a partner around Valentine's day, but others travel as far as spring, until it gets dark and moving through the night. During that time, toads begin migrating from where 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 toad population since he was a boy, explains that "They've got just one focus: to go and mate." If their path happens to a road, they could be killed by traffic, and that mating period would never happen – preventing a new generation of toads from being produced.

Toad Patrols Throughout the United Kingdom

Finding many of dead toads on nearby streets "resonates deeply with people," and has resulted in the formation of rescue teams across the UK – hundreds of organizations are currently registered with a countrywide program. These groups collect toads and carry them over streets in buckets, as well as recording the quantity of toads they find and advocating for other safety solutions, such as blocked roads and underground wildlife tunnels.

Patrols usually work during the migration season, when toad crossings are frequent. However, this implies they can miss groups of toadlets, which, having existed as eggs and then tadpoles, exit their ponds over an irregular timetable in the end of summer. Because of their size – just one or two centimetres wide – "they are destroyed by vehicles." And as being hit "essentially crushes them," it's more difficult to collect information on them. At least when adult toads are killed, their remains can be counted.

Year-Round Efforts

Unlike many groups, a specific volunteer group, who are in their eighth season of functioning, go out year-round – not every night, but when 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 patrol, they admit it is "not ideal conditions" – toad hibernation season has started and it's been a dry day – but several of the helpers willingly accept to walk up and down their area with me and search for any toads. "If anyone can locate any toads tonight, those two will spot one," says the group coordinator, indicating her 14-year-old son and the experienced member. We've been out for 120 minutes without a single toad sighting, and now they have climbed over a barbed wire fence to check under some logs.

Community Involvement

The family duo became part of the patrol a while back. The youngster loves all things wildlife and has an goal to become a conservationist, so his parent started to search for activities they could do jointly to help local wildlife. Now she loves it as much as he does, the middle-aged entrepreneur explains – so when the group was looking for a fresh coordinator lately, she volunteered for the role.

The youth, too, has been instrumental in the group. A video he created, imploring the municipal authority to block a road through a nature reserve during breeding time, influenced the outcome the group's way. After a twelve months of lobbying, the authority agreed to an "restricted access" rule between 5pm and 5am from late winter through to April. Most drivers duly avoided the road.

Additional Species and Challenges

Several vehicles go past when I'm out on patrol and we find some casualties as a consequence – no toads, but several crushed salamanders. We spot one live amphibian as well, and the youngster is especially excited to see a daddy longlegs, which moves in his palms. Yet despite the team's hardest attempts to let me see a toad, the local population has obviously gone dormant for the colder months. It appears that I couldn't have found any better success elsewhere in the nation – all the patrol groups I reach out to clarify that it's very difficult at this time of year.

They project rescuing nearly 10,000 grown amphibians during migration

One email I receive from a different helper, who has kindly made the effort to check for toads in a famous site, considered the largest accurately monitored toad population in the UK, arrives in my inbox with the subject line: "No toads." However, in February and March, he tells me, the team expects to help approximately 10,000 adult toads over the street.

Effectiveness and Challenges

What level of impact can these groups actually make? "The reality that volunteers are performing this consistently on chilly, wet and miserable late nights is remarkable," says an expert. "This effort that very much deserves recognition." However, while rescue teams are able to slow the decline, they can't stop it completely – not least because traffic is just one danger.

Other Dangers

The climate crisis has resulted in extended spells of dry weather, which create the wrong conditions for some of the animals that toads consume, such as worms and slugs, while higher water temperatures have caused an rise of blue-green algae, which can be toxic to toads. Milder winters also cause toads to wake up from their dormancy more often, interfering with the resource preservation crucial to their life cycle. Loss of environment – particularly the disappearance of big water bodies – is an additional threat.

Experts are "often concerned about overemphasizing practical benefits on biodiversity," but "It's important in just their presence." But toads play an significant part in the food chain, consuming pretty much any invertebrates or small animals they can fit in their mouths and in turn feeding a number of birds and mammals, such as hedgehogs and otters. Improving conditions for toads – ie building water habitats, protecting forests and constructing toad tunnels – "benefits for a wide range of additional wildlife."

Historical Significance

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