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 market town in Wiltshire to meet up with local helpers from a toad patrol. These dedicated individuals give up their nights to safeguard the local toad population.

A Worrying Drop 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 need very specific conditions" and "should be able to live quite well in most of habitats in the UK," meaning if even they are not managing to survive, "it kind of suggests that the ecosystem is unbalanced."

Since 1985, Britain's toad numbers have nearly been cut in half

The Threat from Traffic

Though the research didn't examine the causes for the drop, cars certainly plays a part. Estimates indicate that 20 tons of toads are crushed on UK roads annually – in other words, several hundred thousand. In contrast to frogs, which would probably be content to mate "with just a small container," toads prefer big bodies of water. Their capacity to remain away from water for more time than frogs means they can travel further to find them – often hundreds of metres. They tend to follow their ancestral migration routes – it's common for adult toads to return to their birth pond to mate.

Breeding Habits

Fittingly, the first toads start their journey for a mate around Valentine's day, but some move as late as April, waiting until it gets night and travelling through the night. During that period, toads start moving from where they have been hibernating "almost simultaneously."

A local helper, who grew up in the region and has been trying to protect its toad population since he was a boy, explains that "They've got just one focus: to go and have an orgy." If their route happens to a road, they could all get run over, and that breeding season would be lost – stopping a new generation of toads from being produced.

Rescue Groups Throughout the United Kingdom

Finding many of toad carcasses on local roads "resonates deeply with people," and has led to the formation of toad patrols across the UK – 274 groups are officially listed with a national initiative. These groups pick up toads and transport them over streets in buckets, as well as counting the number of toads they encounter and lobbying for other safety solutions, such as blocked roads and underground wildlife tunnels.

Patrols usually work during the breeding period, when amphibian movements are more regular. However, this implies they can overlook groups of toadlets, which, having existed as eggs and then tadpoles, leave their water habitats over an irregular timetable in late summer. Because of their small stature – just one or two centimetres wide – "they are destroyed by vehicles." And as being hit "essentially crushes them," it's harder to get data on them. At least when adult toads are killed, their carcasses can be counted.

Annual Work

In contrast to many groups, a specific volunteer group, who are in their eighth season of operating, go out year-round – not every night, but whenever weather are warm and wet, or if someone has posted about a toad sighting in their messaging app. When I ask to join them on patrol, they admit it is "not ideal conditions" – toad hibernation season has begun and it's been a arid period – 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, that pair will find one," says the group coordinator, indicating her 14-year-old son and the longtime volunteer. After for two hours without a glimpse of any amphibians, and now they have scaled a wire barrier to check under some wood.

Family Involvement

The family duo joined the group a year and a half ago. The teenager loves all things nature-related and has an goal to become a conservationist, so his mother started to search for activities they could do jointly to help native animals. Now she loves it as much as he does, the 41-year-old entrepreneur explains – so when the group was seeking a fresh coordinator recently, she decided to step up.

The teenager, too, has been instrumental in the group. A clip he made, imploring the municipal authority to close a road through a nature reserve during migration season, swung the decision the group's way. After a twelve months of campaigning, the council approved an "access-only" restriction between 5pm and 5am from late winter through to spring. The majority of motorists duly avoided the route.

Additional Species and Difficulties

Several vehicles go by when I'm out on duty and we find some casualties as a consequence – no toads, but three squashed newts. We see one live amphibian as well, and the teenager is especially excited to see a harvestman, which moves in his palms. Yet in spite of the team's best efforts to let me see a toad, the local population has obviously gone dormant for the winter. It appears that I wouldn't have had any more luck anywhere else in the country – all the patrol groups I reach out to explain that it's near-impossible at this time of year.

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

One email I receive from another volunteer, who has kindly made the effort to look for toads in a famous site, thought to be the biggest tracked toad population in the UK, reaches me with the subject line: "No toads." However, in late winter, he informs me, the group plans to assist approximately ten thousand mature amphibians over the street.

Effectiveness and Limitations

How much of a difference can these organizations actually make? "The fact that people are performing this regularly on cold, damp and unpleasant late nights is quite extraordinary," notes 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.

Additional Threats

The climate crisis has meant extended spells of drought, which create the wrong conditions for some of the creatures that toads eat, such as worms and slugs, while warmer ponds have caused an rise of toxic plants, which can be toxic to toads. Milder winters also cause toads to wake up from their hibernation more often, disrupting the energy conservation vital to their existence. Habitat destruction – particularly the loss of big water bodies – is an additional threat.

Researchers are "always a bit worried about putting too much of a utilitarian spin on biodiversity," however "There is a big value in just having these animals around." But toads do have an significant part in the ecosystem, eating pretty much any small creatures or tiny organisms they can swallow and in turn feeding a variety of birds and mammals, such as hedgehogs and otters. Improving situations for toads – ie building water habitats, conserving woodland and constructing toad tunnels – "we'll improve them for a whole bunch of other species."

Historical Importance

Another reason to try to keep toads present is their "historical significance," notes an specialist. Legends and tales around toads go back {centuries|hundred
