It is Friday night at 7:30, but rather than going out or watching a film, I've taken a train to a market town in Wiltshire to meet up with local helpers from a amphibian rescue group. These committed people sacrifice their nights to protect the local toad population.

A Worrying Drop in Population

The Bufo bufo is growing more rare. A latest study led by an amphibian and reptile charity showed that the UK toad population have dropped by half since 1985. Observing a creature that has been a fixture of the UK landscape in decline is described as "worrying" by researchers. Toads "don't need very particular environments" and "ought to live quite well in the majority of habitats in Britain," so if even they are struggling to persist, "it kind of suggests that things are not as they should be."

The Danger from Traffic

Though the study didn't examine the causes for the decline, traffic certainly plays a part. Estimates suggest that 20 tonnes of toads are killed on UK roads every year – in other words, hundreds of thousands. In contrast to frogs, which would probably be content to mate "if you left out a bucket of water," toads prefer big bodies of water. Their capacity to stay out of water for more time than frogs means they can journey farther to reach them – often hundreds of metres. They tend to stick to their ancestral migration routes – it's typical for adult toads to go back to their birth pond to mate.

Breeding Habits

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

A local helper, who was raised 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 have an orgy." If their route crosses a road, they could be killed by traffic, and that mating period would be lost – preventing a next generation of toads from being produced.

Toad Patrols Throughout the UK

Seeing hundreds of dead toads on nearby streets "resonates deeply 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 pick up toads and transport them over streets in buckets, as well as recording the number of toads they encounter and lobbying for other safety solutions, such as road closures and amphibian passages.

Volunteers tend to operate during the migration season, when toad crossings are frequent. However, this means they can overlook groups of toadlets, which, having existed as eggs and then tadpoles, 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 "basically turns them into mush," it's more difficult to get data on them. At least when adult toads are killed, their remains can be counted.

Annual Efforts

Unlike most patrols, one local team, who are in their eighth season of functioning, go out year-round – not every night, but whenever weather are damp, or if a member has posted about a amphibian spotting in their messaging app. When I ask to join them on patrol, they concede it is "not ideal conditions" – winter dormancy has begun and it's been a dry day – but several of the volunteers gamely agree to walk up and down their area 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 experienced member. We've been out for two hours without a single toad sighting, and now they have climbed over a wire barrier to inspect beneath some wood.

Community Involvement

The family duo 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 look for activities they could do together to protect native animals. Now she loves it as much as he does, the 41-year-old entrepreneur explains – so when the team was looking for a new manager lately, she volunteered for the role.

The teenager, too, has been instrumental in the group. A clip he created, imploring the local council to block a street through a protected area during migration season, swung the decision the team's way. After a twelve months of campaigning, the authority agreed to an "access-only" restriction between evening and morning from late winter through to spring. The majority of motorists duly avoided the route.

Additional Species and Difficulties

A few cars go past when I'm out on duty and we discover some casualties as a consequence – no toads, but several crushed salamanders. We spot one live amphibian as well, and the teenager is especially excited to see a harvestman, which dances in his palms. 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 seems that I couldn't have found any better success elsewhere in the nation – all the rescue teams I contact clarify that it's near-impossible at this season.

They project rescuing nearly 10,000 grown amphibians during migration

A message I get from another volunteer, who has generously made the effort to look for toads in a famous site, thought to be the largest accurately monitored toad group in the UK, reaches me with the subject line: "None found." However, in February and March, he informs me, the team plans to assist approximately 10,000 adult toads across the road.

Impact and Challenges

What level of impact can these groups actually make? "The reality that volunteers are performing this consistently on chilly, wet and miserable late nights is remarkable," says an researcher. "This effort that very much should be celebrated." However, while rescue teams are able to reduce the drop, they can't stop it completely – not least because vehicles is just one danger.

Additional Threats

The global warming has meant longer periods of dry weather, which cause the poor environment for some of the creatures that toads eat, such as invertebrates, while higher water temperatures have caused an increase of toxic plants, which can be harmful to toads. Warmer cold seasons also lead toads to wake up from their dormancy more frequently, interfering with the energy conservation vital to their existence. Habitat destruction – especially the disappearance of large ponds – is another menace.

Experts are "always a bit worried about putting too much of a utilitarian spin on wildlife," but "There is a big value in just their presence." But toads do have an important role in the food chain, consuming almost any small creatures or tiny organisms they can swallow and in turn feeding a number of birds and mammals, such as hedgehogs and otters. Improving situations for toads – ie creating more ponds, conserving woodland and installing toad tunnels – "we'll improve them for a whole bunch of additional wildlife."

Cultural Importance

Another reason to work to preserve toads present is their "important cultural value," notes an specialist. Legends and tales around toads go back {centuries|hundred
