It is Friday night at half past seven, but instead of heading to the pub or watching a film, I've taken a train to a town in Wiltshire to join volunteers from a toad patrol. These committed people give up their nights to protect the native amphibian community.

A Worrying Drop in Population

The Bufo bufo is growing more uncommon. A latest study led by an wildlife conservation group revealed that the UK toad population have almost halved since the mid-1980s. Observing a species that has been a fixture of the UK landscape in decline is labeled "concerning" by experts. Toads "don't require very particular environments" and "ought to live quite well in the majority of habitats in the UK," meaning if even they are struggling to persist, "it kind of suggests that the ecosystem is unbalanced."

Since 1985, Britain's toad numbers have nearly been cut in half

The Danger from Traffic

Though the research didn't examine the reasons for the decline, cars is a major factor. Calculations indicate that 20 tonnes of toads are killed on UK roads every year – that is, hundreds of thousands. Unlike frogs, which might be content to mate "if you left out a small container," toads favor big bodies of water. Their ability to remain away from water for more time than frogs allows they can journey farther to reach them – often long distances. They usually follow their traditional paths – it's common for adult toads to return to their natal pond to mate.

Migration Habits

Appropriately enough, the first toads start their journey for a mate around February 14th, but others travel as late as spring, waiting until it gets night and travelling after sunset. During that period, toads begin migrating from wherever they have been hibernating "almost simultaneously."

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

Toad Patrols Across the United Kingdom

Seeing many of dead toads on nearby streets "resonates deeply with people," and has resulted in the formation of rescue teams across the UK – 274 groups are currently registered with a national initiative. These teams collect toads and transport them across roads in containers, as well as counting the number of toads they find and advocating for other safety solutions, such as blocked roads and amphibian passages.

Patrols usually work during the migration season, when toad crossings are more regular. However, this means they can miss numbers of young toads, which, having been spawn and then juveniles, leave their water habitats over an unpredictable schedule in late summer. Because of their size – just one or two centimetres 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 tallied.

Annual Work

In contrast to many groups, one local team, who are in their eighth season of functioning, go out throughout the year – not nightly, but when weather are damp, or if someone has posted about a toad sighting in their messaging app. When I request to accompany them on duty, they concede it is "not a toady night" – toad hibernation season has started and it's been a dry day – but several of the volunteers gamely agree to walk up and down their area with me and see what we can find. "Should anyone can locate any toads tonight, those two will spot one," says the patrol manager, indicating her 14-year-old son and the experienced member. We've been out for 120 minutes without a glimpse of any amphibians, and now they have climbed over a wire barrier to inspect beneath some logs.

Community Involvement

The mother and son became part of the patrol a while back. The teenager adores all things wildlife and has an goal to become a conservationist, so his parent started to look for activities they could do together to help local wildlife. Now she loves it as much as he does, the 41-year-old entrepreneur explains – so when the group was looking for a fresh coordinator lately, she volunteered for the role.

The teenager, too, has been instrumental in the group. A video he made, urging the local council 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 approved an "access-only" restriction between 5pm and 5am from February through to April. The majority of motorists respected and avoided the route.

Additional Species and Challenges

A few cars go by when I'm out on patrol and we discover some victims as a result – no amphibians, but several crushed salamanders. We spot one living newt as well, and the youngster is particularly pleased to see a harvestman, which dances in his hands. Yet in spite of the group's best efforts to let me see a toad, the local population has clearly gone dormant for the winter. It appears that I couldn't have found any more luck elsewhere in the nation – all the rescue teams I contact explain that it's very difficult at this season.

This team anticipates assisting around ten thousand mature toads over the street

One email I get from a different helper, who has kindly made the effort to check for toads in a noted location, considered 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 mature amphibians over the street.

Effectiveness and Challenges

What level of impact can these groups actually make? "The reality that people are performing this consistently on chilly, wet and miserable late nights is quite extraordinary," notes an expert. "This effort that very much deserves recognition." However, while toad patrols are able to slow the decline, they cannot prevent it entirely – partly since traffic is not the only threat.

Other Dangers

The climate crisis has resulted in longer periods of drought, which cause the wrong conditions for some of the animals that toads eat, such as worms and slugs, while higher water temperatures have caused an increase of toxic plants, which can be harmful to toads. Warmer cold seasons also lead toads to emerge from their hibernation more often, disrupting the energy conservation crucial to their life cycle. Loss of environment – particularly the loss of large ponds – is an additional threat.

Experts are "always a bit worried about putting too much of a utilitarian spin on biodiversity," however "There is a big value in just having these animals around." But toads play an significant part in the food chain, consuming pretty much any invertebrates or small animals they can fit in their mouths and in turn sustaining a number of predators, such as hedgehogs and otters. Enhancing situations for toads – ie building water habitats, conserving woodland and installing amphibian passages – "we'll improve them for a wide range of additional wildlife."

Historical Significance

Another reason to try to keep toads present is their "important cultural value," adds an specialist. Myths and folklore around toads date back {centuries|hundred
