It's a Friday evening at 7:30, but instead of heading to the pub or relaxing at home, I've caught a train to a market 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 Population

The common toad is growing more uncommon. A latest research led by an amphibian and reptile charity showed that the British common toad numbers have dropped by half since the mid-1980s. Observing a species that has been a stalwart of the British countryside in decrease is described as "concerning" by researchers. Toads "don't require very specific conditions" and "ought to live quite well in most of habitats in the UK," so 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 Roads

Though the research didn't examine the causes for the drop, cars certainly plays a part. Calculations suggest that 20 tonnes of toads are crushed on British roads every year – in other words, hundreds of thousands. In contrast to frogs, which might be content to mate "with just a small container," toads prefer large ponds. Their ability to stay out of water for more time than frogs allows they can journey farther to reach them – sometimes hundreds of metres. They usually stick to their traditional paths – it's typical for adult toads to return to their birth pond to mate.

Migration Patterns

Appropriately enough, the initial amphibians begin their quest for a partner around Valentine's day, but others travel as far as April, waiting until it gets night and travelling after sunset. During that period, toads start moving from where they have been hibernating "almost simultaneously."

One volunteer, who grew up in the region and has been working to save its amphibians since he was a boy, notes that "They've got just one focus: to go and mate." If their route happens to a street, they could all get run over, and that mating period would never happen – preventing a new generation of toads from being born.

Rescue Groups Across the UK

Finding hundreds of dead toads on local roads "resonates deeply with people," and has resulted in the creation of toad patrols throughout the UK – hundreds of organizations are officially listed with a countrywide program. These groups pick up toads and carry them across roads in buckets, as well as counting the number of toads they encounter and lobbying for other protection measures, such as blocked roads and underground wildlife tunnels.

Volunteers tend to operate during the breeding period, when toad crossings are more regular. However, this implies they can miss groups of toadlets, which, having been eggs and then juveniles, exit their water habitats 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 "essentially crushes them," it's more difficult to get data on them. At least when adult toads are killed, their remains can be counted.

Year-Round Efforts

Unlike most patrols, one local team, who are in their eighth year of operating, go out throughout the year – not nightly, but when conditions are damp, or if someone has reported about a amphibian spotting in their group chat. When I ask to join them on duty, they admit it is "not a toady night" – winter dormancy has started and it's been a dry day – but a few of the helpers gamely agree to walk up and down their area with me and search for any toads. "Should anyone can find any toads tonight, those two will spot one," says the patrol manager, indicating her 14-year-old son and the longtime volunteer. We've been out for two hours without a glimpse of any amphibians, and now they have scaled a wire barrier to check under some logs.

Community Involvement

The mother and son joined 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 jointly to protect native animals. Now she loves it as much as he does, the middle-aged entrepreneur tells me – so when the team was seeking a fresh coordinator recently, she volunteered for the role.

The youth, too, has played an important role in the group. A clip he created, urging the local council to close a road through a nature reserve during migration season, swung the decision the group's way. After a year of lobbying, the authority agreed to an "restricted access" rule between evening and morning from late winter through to spring. The majority of motorists respected and avoided the road.

Additional Species and Challenges

A few vehicles go past when I'm out on patrol and we discover some casualties as a result – no amphibians, but several crushed salamanders. We spot one living newt as well, and the teenager is particularly pleased to see a harvestman, which moves in his hands. Yet despite the team's hardest attempts to show me a toad, the local population has clearly settled down for the winter. It appears that I couldn't have found any better success anywhere else in the country – all the patrol groups I contact explain that it's near-impossible at this time of year.

A message I receive from another volunteer, who has kindly taken the trouble to look for toads in a famous site, thought to be the biggest tracked toad group in the UK, reaches me with the title: "None found." However, in late winter, he informs me, the group expects to help around ten thousand adult toads across the road.

Effectiveness and Limitations

What level of impact can these organizations actually make? "The fact that people are performing this consistently on chilly, wet and miserable late nights is remarkable," says an expert. "That's something that very much should be celebrated." However, while toad patrols are able to slow the decline, they cannot prevent it entirely – partly since traffic is not the only threat.

Additional Threats

The climate crisis has resulted in longer periods of drought, which cause the wrong conditions for some of the animals that toads eat, such as invertebrates, while higher water temperatures have led to an rise of toxic plants, which can be toxic to toads. Warmer cold seasons also lead toads to emerge from their dormancy more frequently, disrupting the resource preservation vital 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 wildlife," but "There is a big value in just having these animals around." But toads play an important role in the ecosystem, eating pretty much any invertebrates or small animals they can swallow and in turn sustaining a variety of predators, such as wildlife. Improving conditions for toads – such as creating more ponds, protecting forests and constructing amphibian passages – "benefits for a whole bunch of additional wildlife."

Historical Importance

An additional motive to work to preserve toads present is their "important cultural value," notes an expert. Myths and folklore around toads date back {centuries|hundred
