It's a Friday night at half past seven, but instead of heading to the pub or watching a film, I've taken a train to a market town in the countryside to join volunteers from a amphibian rescue group. These dedicated individuals sacrifice their nights to safeguard the native amphibian community.

An Alarming Drop in Population

The common toad is becoming increasingly uncommon. A recent research conducted by an amphibian and reptile charity showed that the British common toad numbers have almost halved since 1985. Observing a creature that has been a stalwart of the British countryside in decrease is described as "concerning" by experts. Toads "don't require very specific conditions" and "ought to live successfully in most of areas in the UK," so if even they are not managing to survive, "it indicates that the ecosystem is unbalanced."

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

The Danger from Traffic

Though the study didn't cover the reasons for the drop, traffic certainly plays a part. Calculations indicate that 20 tons of toads are killed on UK roads annually – in other words, hundreds of thousands. In contrast to frogs, which might be content to mate "with just a small container," toads prefer big bodies of water. Their capacity to stay out of water for longer than frogs allows they can travel further to reach them – often long distances. They tend to follow their traditional paths – it's common for adult toads to go back to their birth pond to mate.

Migration Patterns

Fittingly, the first toads start their journey for a partner around Valentine's day, but some move as late as April, until it gets night and moving after sunset. During that time, toads start moving from wherever they have been overwintering "almost simultaneously."

A local helper, who was raised in the area and has been trying to protect its toad population since he was a boy, explains that "Their sole purpose: to go and mate." If their route crosses 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 Throughout the United Kingdom

Finding many of dead toads on nearby streets "inherently strikes a chord with people," and has led to the creation of toad patrols across the UK – 274 groups are officially listed with a national initiative. These groups collect toads and transport them over streets in containers, as well as recording the quantity of toads they find and lobbying for other protection measures, such as road closures and underground wildlife tunnels.

Patrols tend to operate during the breeding period, when toad crossings are frequent. However, this implies they can overlook groups of young toads, which, having existed as spawn and then tadpoles, leave their ponds over an unpredictable schedule in late summer. Because of their size – just a couple of cm wide – "they are destroyed by vehicles." And as being hit "basically turns them into mush," it's harder to get data on them. At least when adult toads are killed, their remains can be counted.

Annual Work

Unlike most patrols, one local team, who are in their eighth year of functioning, go out throughout the year – not nightly, but whenever weather are damp, or if someone has posted about a toad sighting in their messaging app. When I request to accompany them on patrol, they concede it is "not ideal conditions" – winter dormancy has begun and it's been a arid period – but several of the volunteers willingly accept 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 patrol manager, indicating her 14-year-old son and the longtime volunteer. After for 120 minutes without a single toad sighting, and now they have climbed over a wire barrier to inspect beneath some wood.

Community Participation

The family duo joined the patrol a year and a half ago. The teenager adores all things wildlife and has an ambition to become a environmentalist, so his mother started to search for activities they could do together to help native animals. Now she loves it as much as he does, the middle-aged entrepreneur tells me – so when the team was seeking a new manager recently, she volunteered for the role.

The teenager, too, has been instrumental in the group. A video he made, imploring the local council to block a street through a protected area during migration season, swung the decision the team's way. After a year of lobbying, the council agreed to an "restricted access" rule between evening and morning from February through to April. The majority of motorists respected and avoided the route.

Other Wildlife and Difficulties

A few vehicles go by when I'm out on duty and we discover some casualties as a consequence – no toads, but three squashed newts. We spot one live amphibian as well, and the teenager is particularly pleased to see a harvestman, which dances in his hands. Yet in spite of the team's best efforts to show me a toad, the local population has obviously settled down for the colder months. It seems that I couldn't have found any more luck anywhere else in the country – all the rescue teams I contact explain that it's near-impossible 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 taken the trouble to check for toads in a noted location, considered the largest accurately monitored toad population in the UK, reaches me with the title: "None found." However, in February and March, he tells me, the team expects to help around 10,000 mature amphibians across the road.

Impact and Challenges

How much of a difference can these organizations actually make? "The reality that volunteers are doing this consistently on chilly, wet and miserable late nights is remarkable," notes an researcher. "That's something that very much should be celebrated." However, while toad patrols are able to reduce the drop, they can't stop it completely – not least because traffic is not the only threat.

Other Dangers

The climate crisis has meant extended spells of drought, which cause the poor environment for some of the creatures that toads consume, such as invertebrates, while higher water temperatures have led to an increase of blue-green algae, which can be harmful to toads. Warmer cold seasons also lead toads to wake up from their hibernation more often, disrupting the energy conservation crucial to their life cycle. Loss of environment – especially the disappearance of large ponds – is another menace.

Experts are "often concerned about overemphasizing practical benefits on wildlife," however "It's important in just having these animals around." But toads do have an significant part in the ecosystem, consuming pretty much any small creatures or small animals they can swallow and in turn feeding a number of birds and mammals, such as wildlife. Enhancing conditions for toads – ie building water habitats, conserving woodland and constructing toad tunnels – "benefits for a wide range of additional wildlife."

Cultural Significance

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