It's Friday evening at half past seven, but rather than heading to the pub or watching a film, I've taken a train to a market town in Wiltshire to join local helpers from a amphibian rescue group. These committed people give up their evenings to safeguard the local toad population.

An Alarming Decline in Numbers

The common toad is becoming increasingly rare. A latest study led by an amphibian and reptile charity revealed that the British common toad numbers have almost halved since the mid-1980s. Seeing a creature that has been a fixture of the UK landscape in decline is described as "concerning" by researchers. Toads "don't require very specific conditions" and "ought to live quite well in most of habitats in Britain," meaning if even they are struggling to persist, "it indicates that things are not as they should be."

The Threat from Roads

Though the study didn't examine the reasons for the decline, traffic certainly plays a part. Calculations indicate that 20 tonnes of toads are crushed on British roads every year – that is, hundreds of thousands. Unlike frogs, which might be happy to mate "if you left out a small container," toads prefer big bodies of water. Their ability to remain away from water for longer than frogs means they can journey farther to reach them – often long distances. They tend to stick to their traditional paths – it's typical for mature amphibians to return to their natal pond to mate.

Breeding Habits

Fittingly, the first toads start their journey for a partner around February 14th, but others travel as late as April, waiting until it gets dark and travelling through the night. During that time, toads begin migrating from where 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, explains that "They've got just one focus: to go and have an orgy." If their route happens to a street, they could be killed by traffic, and that breeding season would be lost – stopping a new generation of toads from being produced.

Toad Patrols Across the UK

Seeing many of toad carcasses on local roads "resonates deeply with people," and has resulted in the formation of toad patrols throughout the UK – 274 groups are officially listed with a national initiative. These teams pick up toads and carry them across roads in buckets, as well as counting the quantity of toads they find and lobbying for other safety solutions, such as blocked roads and underground wildlife tunnels.

Volunteers tend to operate 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 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 more difficult to collect information on them. At least when adult toads are killed, their remains can be counted.

Annual Work

Unlike most patrols, a specific volunteer group, who are in their eighth season of functioning, go out year-round – not nightly, but when conditions are damp, or if a member has reported about a amphibian spotting in their group chat. When I ask to join them on duty, they admit it is "not ideal conditions" – toad hibernation season has started and it's been a dry day – but several of the helpers gamely agree to patrol their area with me and search for any toads. "If anyone can find any toads tonight, that pair will find one," says the group coordinator, pointing to her 14-year-old son and the experienced member. After for 120 minutes without a single toad sighting, and now they have climbed over a barbed wire fence to check under some logs.

Community Participation

The family duo joined the group a year and a half ago. The youngster loves all things nature-related and has an goal to become a environmentalist, so his parent started to search for things they could do jointly to protect native animals. Now she loves it as much as he does, the middle-aged small business owner explains – so when the group was seeking a fresh coordinator lately, she volunteered for the role.

The teenager, too, has been instrumental in the group. A video he made, urging the municipal authority to block a street through a protected area during migration season, influenced the outcome the group's way. After a year of campaigning, the authority approved an "restricted access" rule between evening and morning from late winter through to April. Most drivers respected and avoided the route.

Other Wildlife and Difficulties

Several cars go past when I'm out on duty and we discover some casualties as a result – no toads, but several crushed salamanders. We see one live amphibian as well, and the teenager is particularly pleased to see a harvestman, which dances in his palms. Yet despite the team's best efforts to let me see a toad, the native community has clearly gone dormant 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 very difficult at this season.

A message I receive from a different helper, who has kindly taken the trouble to look for toads in a noted location, considered the biggest tracked toad population in the UK, reaches me with the title: "No toads." However, in late winter, he tells me, the team plans to assist approximately ten thousand adult toads over the street.

Impact and Limitations

How much of a difference can these groups actually make? "The reality that people are doing this regularly on chilly, wet and miserable late nights is remarkable," says an researcher. "That's something that very much should be celebrated." However, while toad patrols are able to slow the decline, they cannot prevent it entirely – partly since traffic is just one danger.

Additional Threats

The climate crisis has meant longer periods of drought, which create the poor environment for some of the animals 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. Loss of environment – particularly the disappearance of big water bodies – is another menace.

Experts are "always a bit worried about putting too much of a utilitarian spin on biodiversity," but "There is a big value in just having these animals around." But toads do have an significant part in the food chain, eating pretty much any small creatures or tiny organisms they can fit in their mouths and in turn feeding a number of birds and mammals, such as wildlife. Improving situations for toads – ie building water habitats, conserving woodland and installing toad tunnels – "benefits for a whole bunch of other species."

Cultural Importance

An additional motive to work to preserve toads around is their "historical significance," adds an expert. Legends and tales around toads go back {centuries|hundred
