It's a Friday night at half past seven, but instead of going out or relaxing at home, I've taken a train to a town in Wiltshire to join volunteers from a amphibian rescue group. These committed people sacrifice their nights to protect the local toad population.

A Worrying Decline in Numbers

The Bufo bufo is becoming increasingly rare. A recent study conducted by an amphibian and reptile charity revealed that the British common toad numbers have almost halved since the mid-1980s. Observing a species that has been a stalwart of the British countryside in decline is labeled "concerning" by experts. Toads "don't require very particular environments" and "should be able to live successfully in most of habitats 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 Threat from Roads

Though the study didn't examine the reasons for the decline, cars certainly plays a part. Estimates suggest that 20 tonnes of toads are killed on UK roads every year – that is, several hundred thousand. In contrast to frogs, which would probably be content to mate "if you left out a bucket of water," toads prefer large ponds. Their capacity to remain away from water for longer than frogs means they can journey farther to reach them – often hundreds of metres. They usually stick to their ancestral migration routes – it's typical for adult toads to go back to their natal pond to mate.

Migration Patterns

Fittingly, the first toads begin their quest for a mate around Valentine's day, but others travel as far as April, waiting until it gets dark and moving after sunset. During that time, toads start moving from where they have been hibernating "all pretty much at the same time."

One volunteer, who grew up in the region and has been trying to protect its toad population since he was a boy, notes that "Their sole purpose: to go and mate." If their route happens to a road, they could all get run over, and that breeding season would be lost – stopping a next 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 national initiative. These teams collect toads and carry them across roads in buckets, as well as recording the quantity of toads they encounter and advocating for other safety solutions, such as road closures and underground wildlife tunnels.

Patrols tend to operate during the breeding period, when toad crossings are frequent. However, this means they can overlook groups of young toads, which, having been spawn and then juveniles, leave their ponds over an irregular timetable in late summer. Because of their small stature – 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 Efforts

Unlike many groups, one local team, who are in their eighth year of functioning, go out year-round – not nightly, but when conditions are damp, or if someone has reported about a toad sighting in their group chat. When I request to accompany them on patrol, they admit it is "not a toady night" – winter dormancy has started and it's been a arid period – but several of the volunteers gamely agree to patrol their area with me and see what we can find. "Should anyone can find any toads tonight, those two will find 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 single toad sighting, and now they have climbed over a wire barrier to check under some wood.

Family Participation

The mother and son became part of the patrol a while back. The youngster loves all things nature-related and has an ambition to become a environmentalist, so his mother started to search for activities they could do together to protect local wildlife. Now she loves it as much as he does, the 41-year-old small business owner explains – so when the group was looking for a new manager lately, she volunteered for the role.

The youth, too, has been instrumental in the organization. A video he made, imploring the municipal authority to close a street 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 spring. The majority of motorists duly avoided the road.

Other Wildlife and Challenges

A few vehicles go past when I'm out on patrol and we find some casualties as a consequence – no amphibians, but three squashed newts. We see one living newt as well, and the youngster is particularly pleased to see a daddy longlegs, which moves in his hands. Yet in spite of the team's hardest attempts to let me see a toad, the local population has clearly settled down for the colder months. It appears that I wouldn't have had any better success anywhere else in the nation – all the rescue teams I reach out to clarify that it's near-impossible at this time of year.

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

A message I receive from another volunteer, who has generously made the effort to look for toads in a noted location, thought to be the biggest tracked toad group in the UK, reaches me with the subject line: "No toads." However, in late winter, he tells me, the team expects to help approximately ten thousand adult toads across the road.

Impact and Challenges

What level of impact can these organizations truly achieve? "The reality that volunteers are doing this regularly on chilly, wet and miserable late nights is quite extraordinary," says an researcher. "This effort that very much deserves recognition." However, while rescue teams are able to slow the decline, they cannot prevent it entirely – not least because vehicles is just one danger.

Additional Threats

The global warming has meant longer periods of dry weather, which create the poor environment for some of the animals that toads eat, such as worms and slugs, while warmer ponds have caused an rise of blue-green algae, which can be toxic to toads. Warmer cold seasons also cause toads to emerge from their dormancy more frequently, disrupting the resource preservation vital to their life cycle. Loss of environment – especially the loss of big water bodies – is an additional threat.

Experts are "always a bit worried about putting too much of a utilitarian spin on wildlife," however "It's important in just their presence." But toads play an important role in the ecosystem, consuming almost any small creatures or tiny organisms they can fit in their mouths and in turn feeding a variety of birds and mammals, such as wildlife. Improving situations for toads – ie building water habitats, conserving woodland and constructing amphibian passages – "benefits for a wide range of additional wildlife."

Historical Importance

Another reason to work to preserve toads present is their "historical significance," notes an specialist. Myths and folklore around toads go back {centuries|hundred
