It is Friday night at 7:30, but rather than going out or relaxing at home, I've taken a train to a market town in Wiltshire to join volunteers from a amphibian rescue group. These committed people sacrifice their evenings to safeguard the native amphibian community.

A Worrying Drop in Population

The common toad is growing more uncommon. A latest study led by an amphibian and reptile charity showed that the UK toad population have dropped by half since 1985. Observing a species that has been a fixture of the UK landscape in decrease is labeled "concerning" by experts. Toads "don't require very specific conditions" and "should be able to live quite well in the majority of habitats in Britain," so if even they are not managing to survive, "it kind of suggests that things are not as they should be."

Toad populations across the UK have declined by almost 50% since the 1980s

The Threat from Roads

Though the study didn't cover the reasons for the drop, cars is a major factor. Calculations indicate that 20 tonnes of toads are crushed on British roads every year – in other words, hundreds of thousands. Unlike frogs, which might be happy to mate "with just a bucket of water," toads prefer large ponds. Their ability to remain away from water for more time than frogs allows they can travel further to reach them – sometimes long distances. They usually follow their ancestral migration routes – it's typical for mature amphibians to go back to their birth pond to mate.

Migration Habits

Fittingly, the initial amphibians start their journey for a partner around Valentine's day, but others travel as far as spring, until it gets dark and moving through the night. During that period, toads begin migrating from wherever they have been hibernating "all pretty much at the same time."

One volunteer, who grew up in the area and has been trying to protect its toad population since he was a child, notes that "They've got just one focus: to go and have an orgy." If their path happens to a street, they could all get run over, and that breeding season would be lost – preventing a new generation of toads from being born.

Rescue Groups Across the UK

Seeing hundreds of dead toads on nearby streets "inherently strikes a chord with people," and has led to the creation of toad patrols throughout the UK – hundreds of organizations are currently registered with a countrywide program. These groups pick up toads and transport them across roads in containers, as well as counting the quantity of toads they find and advocating for other protection measures, such as road closures and underground wildlife tunnels.

Volunteers tend to operate during the migration season, when amphibian movements are frequent. However, this implies they can miss numbers of toadlets, which, having existed as spawn and then juveniles, exit their ponds over an irregular timetable in the end of summer. Because of their size – just a couple of cm wide – "they can get obliterated by car traffic." And as being hit "basically turns them into mush," it's harder to collect information on them. At least when mature amphibians are lost, their remains can be tallied.

Year-Round Work

Unlike most patrols, one local team, who are in their eighth year of operating, go out throughout the year – not nightly, but whenever conditions are damp, or if someone has reported about a amphibian spotting in their messaging app. 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 several of the helpers willingly accept to patrol their area with me and search for any toads. "If anyone can find any toads tonight, those two will find one," says the group coordinator, indicating her teenage child and the experienced member. We've been out for two hours without a glimpse of any amphibians, and now they have scaled a wire barrier to inspect beneath some logs.

Community Participation

The mother and son became part of the patrol a while back. The youngster adores all things nature-related and has an ambition to become a environmentalist, so his parent started to search for activities they could do together to protect native animals. Now she loves it as much as he does, the 41-year-old small business owner tells me – so when the team was seeking a new manager recently, she decided to step up.

The youth, too, has played an important role in the group. A video he created, urging the municipal authority to close a street through a nature reserve during migration season, influenced the outcome the team's way. After a year of lobbying, the council agreed to an "access-only" restriction between 5pm and 5am from February through to spring. Most drivers duly avoided the road.

Other Wildlife and Difficulties

A few cars go by when I'm out on patrol and we discover some victims as a result – no amphibians, but three squashed newts. 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 show me a toad, the native community has obviously gone dormant for the colder months. It seems that I wouldn't have had any more luck elsewhere in the country – all the patrol groups I reach out to explain that it's near-impossible at this time of year.

One email I receive from another volunteer, who has kindly taken the trouble to check for toads in a famous site, considered the biggest tracked toad group in the UK, arrives in my inbox with the title: "No toads." However, in February and March, he informs me, the team plans to assist approximately ten thousand adult toads across the road.

Effectiveness and Challenges

How much of a difference can these groups truly achieve? "The reality that people are performing this regularly on chilly, wet and miserable late nights is remarkable," says an researcher. "This effort that very much deserves recognition." However, while toad patrols are able to reduce the drop, they can't stop it completely – not least because traffic is just one danger.

Additional Threats

The climate crisis has meant longer periods of dry weather, which cause 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 harmful to toads. Milder winters also cause toads to wake up from their hibernation more frequently, interfering with the energy conservation vital to their life cycle. Habitat destruction – particularly the loss of big water bodies – is an additional threat.

Researchers are "always a bit worried about overemphasizing practical benefits on wildlife," but "It's important in just having these animals around." But toads do have an important role in the food chain, eating almost any invertebrates or tiny organisms they can swallow and in turn feeding a variety of birds and mammals, such as hedgehogs and otters. Improving conditions for toads – ie building water habitats, conserving woodland and installing amphibian passages – "benefits for a wide range of additional wildlife."

Historical Importance

Another reason to work to preserve toads present is their "historical significance," adds an specialist. Myths and folklore around toads date back {centuries|hundred
