It's Friday night at half past seven, but rather than going out or relaxing at home, I've caught a train to a town in Wiltshire to join local helpers from a toad patrol. These committed people give up their nights to safeguard the native amphibian community.

A Worrying Decline in Population

The Bufo bufo is growing more rare. A latest research led by an wildlife conservation group revealed that the British common toad numbers have dropped by half since the mid-1980s. Seeing a species that has been a fixture of the British countryside in decline is labeled "worrying" by researchers. Toads "don't need very particular environments" and "ought to live successfully 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."

The UK toad population has almost halved since 1985

The Danger from Roads

Though the research didn't cover the causes for the drop, cars certainly plays a part. Calculations suggest that 20 tonnes of toads are crushed on UK roads every year – in other words, several hundred thousand. Unlike frogs, which might be happy to mate "if you left out a small container," toads prefer large ponds. Their capacity to remain away from water for more time than frogs allows they can travel further to find them – sometimes long distances. They usually stick to their ancestral migration routes – it's typical for mature amphibians to return to their birth pond to mate.

Breeding Patterns

Appropriately enough, the initial amphibians start their journey for a mate around February 14th, but some move as far as April, until it gets dark and travelling through the night. During that period, toads start moving from where they have been hibernating "almost simultaneously."

One volunteer, who grew up 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 path crosses a street, they could all get run over, and that mating period would be lost – stopping a new generation of toads from being born.

Toad Patrols Across the United Kingdom

Seeing many of toad carcasses on nearby streets "resonates deeply with people," and has led to the formation of rescue teams throughout the UK – 274 groups are officially listed with a countrywide program. These teams collect toads and carry them across roads in buckets, as well as counting the quantity of toads they find and advocating for other safety solutions, such as road closures and underground wildlife tunnels.

Patrols tend to operate during the migration season, when amphibian movements are more regular. However, this implies they can miss 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 size – just one or two centimetres wide – "they are destroyed by car traffic." And as being run over "basically turns them into mush," it's harder 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, a specific volunteer group, who are in their eighth season of operating, go out year-round – not nightly, but when weather are warm and wet, or if a member has reported about a amphibian spotting in their group chat. When I request to accompany them on duty, they concede it is "not ideal conditions" – toad hibernation season has started and it's been a arid period – but a few of the helpers willingly accept to walk up and down their route with me and see what we can find. "If anyone can find any toads tonight, that pair will find one," says the patrol manager, indicating her teenage child and the longtime volunteer. After for 120 minutes without a glimpse of any amphibians, and now they have climbed over a barbed wire fence to check under some logs.

Family Involvement

The family duo became part of the patrol a year and a half ago. The teenager loves all things nature-related and has an ambition to become a environmentalist, so his parent started to look for things they could do together to help native animals. Now she loves 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 youth, too, has played an important role in the organization. A video he made, urging the local council to block a road through a protected area during breeding time, swung the decision the group's way. After a year of lobbying, the council approved an "restricted access" rule between evening and morning from February through to April. Most drivers duly avoided the road.

Other Wildlife and Challenges

A few cars go by when I'm out on duty and we find some victims as a consequence – no toads, but several crushed salamanders. We see one live amphibian as well, and the teenager is especially excited to see a daddy longlegs, which moves in his hands. Yet despite the group's hardest attempts to let me see a toad, the local population has clearly gone dormant for the colder months. It appears that I wouldn't have had any more luck elsewhere in the country – all the patrol groups I reach out to clarify 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 get from another volunteer, who has kindly made the effort to look for toads in a famous site, thought to be the largest accurately monitored toad population in the UK, arrives in my inbox with the subject line: "None found." However, in late winter, he tells me, the team expects to help approximately 10,000 adult toads over the street.

Impact and Challenges

What level of impact can these groups truly achieve? "The reality that volunteers are performing this consistently on cold, damp and unpleasant evenings is quite extraordinary," notes an expert. "This effort that very much should be celebrated." However, while toad patrols are able to slow the decline, they can't stop it completely – partly since traffic is just one danger.

Other Dangers

The climate crisis has resulted in extended spells of drought, which create the wrong conditions for some of the creatures that toads consume, such as invertebrates, while higher water temperatures have caused an rise of toxic plants, which can be harmful to toads. Warmer cold seasons also lead toads to wake up from their hibernation more often, disrupting the energy conservation crucial to their life cycle. Habitat destruction – particularly the loss of big water bodies – is another menace.

Researchers are "always a bit worried about overemphasizing practical benefits on wildlife," however "It's important in just having these animals around." But toads play an important role in the ecosystem, eating pretty much any small creatures or small animals they can swallow and in turn sustaining a number of birds and mammals, such as wildlife. Improving conditions for toads – ie creating more ponds, conserving woodland and constructing toad tunnels – "benefits for a wide range of additional wildlife."

Historical Importance

An additional motive to try to keep toads around is their "historical significance," notes an specialist. Myths and folklore around toads go back {centuries|hundred
