It's a Friday evening at half past seven, but rather than going out or watching a film, I've caught a train to a town in Wiltshire to join volunteers from a amphibian rescue group. These dedicated individuals give up their nights to protect the native amphibian community.

A Worrying Decline in Population

The common toad is growing more uncommon. A recent study conducted by an wildlife conservation group showed that the UK toad population have dropped by half since the mid-1980s. Observing a species that has been a stalwart of the UK landscape in decline is described as "concerning" by researchers. Toads "don't need very specific conditions" and "should be able to live quite well in the majority of habitats in the UK," so if even they are not managing to survive, "it indicates that the ecosystem is unbalanced."

The Danger from Roads

Though the research didn't cover the reasons for the drop, cars certainly plays a part. Estimates indicate that 20 tonnes of toads are crushed on British roads annually – in other words, hundreds of thousands. Unlike frogs, which might be happy to mate "with just a small container," toads favor big bodies of water. Their capacity to remain away from water for longer than frogs allows they can travel further to reach them – sometimes 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.

Breeding Patterns

Fittingly, the initial amphibians begin their quest for a partner around February 14th, but others travel as late as April, until it gets dark and travelling through the night. During that period, toads begin migrating from where they have been hibernating "all pretty much at the same time."

A local helper, who was raised in the area and has been working to save its toad population since he was a child, explains that "Their sole purpose: to go and have an orgy." If their path happens to a road, they could all get run over, and that breeding season would never happen – stopping a next generation of toads from being produced.

Rescue Groups Across the United Kingdom

Finding many of toad carcasses on local roads "inherently strikes a chord with people," and has resulted in the formation of toad patrols across the UK – 274 groups are officially listed with a countrywide program. These groups collect toads and transport them over streets in containers, as well as counting the number of toads they encounter and lobbying for other safety solutions, such as blocked roads and underground wildlife tunnels.

Volunteers usually work during the breeding period, when amphibian movements are more regular. However, this means they can miss groups of toadlets, which, having been eggs and then juveniles, leave their water habitats over an irregular timetable in the end of summer. Because of their size – just one or two centimetres wide – "they can get obliterated by car traffic." And as being run over "essentially crushes them," it's harder to collect information on them. At least when adult toads are killed, their carcasses can be tallied.

Year-Round Work

Unlike most patrols, a specific volunteer group, who are in their eighth season of functioning, go out year-round – not every night, but when weather are damp, or if someone has reported about a toad sighting in their group chat. When I request to accompany them on patrol, they concede it is "not ideal conditions" – winter dormancy has started and it's been a arid period – but several of the volunteers gamely agree to patrol their route with me and search for any toads. "Should anyone can locate any toads tonight, those two will spot one," says the group coordinator, indicating her 14-year-old son and the longtime volunteer. After for two hours without a single toad sighting, and now they have climbed over a barbed wire fence to check under some wood.

Community Involvement

The family duo became part of the patrol a while back. The teenager loves all things wildlife and has an ambition to become a environmentalist, so his mother started to search for things they could do jointly to protect native animals. Now she enjoys it as much as he does, the middle-aged small business owner tells me – so when the team was seeking a fresh coordinator lately, she volunteered for the role.

The youth, too, has been instrumental in the organization. A video he created, urging the local council to block a road through a protected area during migration season, swung the decision the group's way. After a year of campaigning, the council approved an "restricted access" restriction between 5pm and 5am from February through to April. The majority of motorists respected and avoided the route.

Additional Species and Challenges

Several cars go past when I'm out on duty and we find some victims as a result – no toads, but several crushed salamanders. We see one living newt as well, and the youngster is especially excited to see a daddy longlegs, which dances in his hands. Yet despite the group's best efforts to let me see a toad, the native community has clearly gone dormant for the winter. It seems that I couldn't have found any more luck anywhere else in the nation – all the rescue teams I reach out to explain that it's very difficult at this time of year.

The group expects to help approximately 10,000 adult toads across the road

A message I receive from a different helper, who has generously taken the trouble to look for toads in a famous site, thought to be the largest accurately monitored toad group in the UK, arrives in my inbox with the subject line: "No toads." However, in February and March, he informs me, the team plans to assist around 10,000 adult toads across the road.

Impact and Challenges

How much of a difference can these organizations truly achieve? "The reality that volunteers are doing this consistently on chilly, wet and miserable late nights is quite extraordinary," notes an researcher. "That's something that very much deserves recognition." However, while rescue teams are able to slow the decline, they can't stop it completely – not least because vehicles is not the only threat.

Other Dangers

The climate crisis has meant extended spells of dry weather, which cause the wrong conditions for some of the creatures that toads consume, such as invertebrates, while warmer ponds have caused an increase of toxic plants, which can be toxic to toads. Milder winters also cause toads to wake up from their hibernation more frequently, disrupting the energy conservation vital to their existence. Loss of environment – particularly the disappearance of big water bodies – is an additional threat.

Researchers are "always a bit worried about overemphasizing practical benefits on biodiversity," but "It's important in just having these animals around." But toads play an significant part in the food chain, eating pretty much any invertebrates or small animals they can swallow and in turn sustaining a number of birds and mammals, such as hedgehogs and otters. Improving situations for toads – ie creating more ponds, protecting forests and installing amphibian passages – "we'll improve them for a wide range of additional wildlife."

Cultural Importance

An additional motive to work to preserve toads around is their "important cultural value," adds an specialist. Legends and tales around toads go back {centuries|hundred
