It's Friday night at 7:30, but rather than heading to the pub or watching a film, I've taken a train to a market town in Wiltshire to join volunteers from a amphibian rescue group. These dedicated individuals sacrifice their evenings to protect the local toad population.

A Worrying Decline in Numbers

The common toad is becoming increasingly uncommon. A latest study conducted by an amphibian and reptile charity showed that the British common toad numbers have dropped by half since the mid-1980s. Seeing a creature that has been a fixture of the British countryside in decrease is described as "worrying" by experts. Toads "don't need very particular environments" and "ought to live quite well in most of habitats in the UK," so if even they are struggling to persist, "it indicates that things are not as they should be."

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

The Danger from Roads

Though the study didn't cover the causes for the decline, traffic certainly plays a part. Estimates suggest that 20 tonnes of toads are crushed on UK roads annually – that is, hundreds of thousands. Unlike frogs, which would probably be content to mate "with just a bucket of water," toads favor big bodies of water. Their capacity to stay out of water for longer than frogs allows they can travel further to find them – sometimes hundreds of metres. They tend to 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 begin their quest for a mate around Valentine's day, but others travel as late as April, until it gets night and moving after sunset. During that period, toads begin migrating from where they have been overwintering "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 boy, notes that "They've got just one focus: to go and mate." If their path happens to a street, they could all get run over, and that mating period would never happen – stopping a next generation of toads from being produced.

Toad Patrols Throughout the United Kingdom

Seeing many of toad carcasses on local roads "inherently strikes a chord with people," and has led to the creation of rescue teams 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 recording the number of toads they encounter and advocating for other protection measures, such as road closures and underground wildlife tunnels.

Volunteers tend to operate during the breeding period, when amphibian movements are frequent. However, this implies they can overlook numbers of young toads, which, having existed as spawn and then juveniles, leave their water habitats over an unpredictable schedule in the end of summer. Because of their small stature – just a couple of cm wide – "they can get obliterated by vehicles." And as being run over "essentially crushes them," it's more difficult to collect information on them. At least when adult toads are killed, their remains can be counted.

Year-Round Efforts

In contrast to many groups, one local team, who are in their eighth season of operating, go out throughout the year – not every night, but when weather are damp, or if someone has reported about a toad sighting in their group chat. When I ask to join them on patrol, they concede it is "not a toady night" – toad hibernation season has started and it's been a dry day – but several of the helpers willingly accept to patrol their area with me and see what we can find. "Should anyone can find any toads tonight, that pair will find 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 Participation

The family duo became part of the patrol a while back. The teenager adores all things nature-related and has an goal to become a environmentalist, so his parent started to look for things they could do together to protect native animals. Now she enjoys it as much as he does, the 41-year-old entrepreneur tells me – so when the group was seeking a fresh coordinator recently, she volunteered for the role.

The teenager, too, has played an important role in the group. A video he made, imploring the municipal authority to close a street through a protected area during migration season, influenced the outcome the team's way. After a year of campaigning, the authority agreed to an "access-only" restriction between 5pm and 5am from late winter through to spring. The majority of motorists respected and avoided the road.

Additional Species and Challenges

A few vehicles go past when I'm out on patrol and we find some casualties as a consequence – no toads, but three squashed newts. We spot one living newt as well, and the youngster is particularly pleased to see a daddy longlegs, which dances in his hands. Yet in spite of the team's best efforts to show me a toad, the native community has clearly gone dormant for the colder months. It seems that I wouldn't have had any better success elsewhere in the nation – all the rescue teams I contact explain that it's very difficult 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 taken the trouble to look for toads in a noted location, considered the biggest tracked toad group in the UK, reaches me with the title: "None found." However, in late winter, he informs me, the team expects to help around ten thousand adult toads over the street.

Impact and Challenges

What level of impact can these organizations actually make? "The fact that people are performing this regularly on cold, damp and unpleasant late nights is remarkable," says an researcher. "This effort that very much deserves recognition." However, while rescue teams are able to slow the decline, they cannot prevent it entirely – partly since vehicles is not the only threat.

Other Dangers

The climate crisis has resulted in longer periods of dry weather, which cause the poor environment for some of the creatures that toads eat, such as worms and slugs, while warmer ponds have caused an rise of blue-green algae, which can be harmful to toads. Warmer cold seasons also lead toads to emerge from their hibernation more often, interfering with the energy conservation crucial to their life cycle. Habitat destruction – especially the disappearance of big water bodies – is an additional threat.

Experts are "always a bit worried about overemphasizing practical benefits on wildlife," however "It's important in just their presence." But toads do have an important role in the food chain, eating almost any small creatures or tiny organisms they can fit in their mouths and in turn feeding a number of predators, such as hedgehogs and otters. Enhancing situations for toads – ie building water habitats, conserving woodland and installing toad tunnels – "benefits for a whole bunch of other species."

Historical Importance

Another reason to work to preserve toads around is their "important cultural value," notes an specialist. Myths and folklore around toads date back {centuries|hundred
