It's a Friday night at 7:30, but instead of heading to the pub or watching a film, I've caught a train to a town in the countryside to meet up with volunteers from a toad patrol. These dedicated individuals give up their evenings to protect the native amphibian community.

An Alarming Decline in Population

The common toad is becoming increasingly rare. A recent study led by an amphibian and reptile charity revealed that the UK toad population have dropped by half since 1985. Observing a species that has been a fixture of the UK landscape in decline is described as "concerning" by experts. Toads "don't need very particular environments" and "should be able to live successfully in the majority of habitats in Britain," meaning if even they are struggling to persist, "it indicates that the ecosystem is unbalanced."

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

The Threat from Roads

Though the study didn't cover the causes for the drop, cars is a major factor. Calculations suggest that 20 tons of toads are crushed on UK roads annually – that is, several hundred thousand. Unlike frogs, which might be content to mate "if you left out a small container," toads favor large ponds. Their ability to stay out of water for longer than frogs means they can journey farther to reach them – often hundreds of metres. They usually follow their traditional paths – it's typical for adult toads to return to their natal pond to mate.

Breeding Patterns

Fittingly, the first toads start their journey for a mate around Valentine's day, but others travel as far as spring, until it gets dark and travelling through the night. During that time, toads start moving from where they have been hibernating "almost simultaneously."

A local helper, who grew up in the area and has been working to save its amphibians since he was a boy, explains that "Their sole purpose: to go and have an orgy." If their route happens to a road, they could be killed by traffic, and that breeding season would be lost – stopping a next generation of toads from being born.

Rescue Groups Throughout the United Kingdom

Seeing hundreds of dead toads on nearby streets "resonates deeply with people," and has led to the creation of rescue teams across the UK – 274 groups are officially listed with a national initiative. These groups collect toads and carry them across roads in containers, as well as recording the quantity of toads they find and advocating for other protection measures, such as blocked roads and underground wildlife tunnels.

Volunteers tend to operate during the migration season, when amphibian movements are frequent. However, this means they can miss numbers of young toads, which, having existed as spawn and then juveniles, exit their water habitats over an unpredictable schedule in the end of summer. Because of their small stature – just one or two centimetres wide – "they are destroyed by car traffic." And as being run over "basically turns them into mush," it's more difficult to collect information on them. At least when mature amphibians are lost, their carcasses can be tallied.

Year-Round Work

Unlike many groups, a specific volunteer group, who are in their eighth season of operating, go out throughout the year – not every night, but when weather are warm and wet, or if a member has reported about a amphibian spotting in their messaging app. When I request to accompany them on duty, they concede it is "not ideal conditions" – winter dormancy has begun and it's been a dry day – but several of the volunteers willingly accept 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 find one," says the patrol manager, indicating her 14-year-old son and the longtime volunteer. After for two hours without a single toad sighting, and now they have scaled a wire barrier to inspect beneath some logs.

Family Involvement

The family duo joined the group a year and a half ago. The youngster adores all things nature-related and has an goal to become a conservationist, so his mother started to look for activities they could do jointly to help native animals. Now she loves it as much as he does, the 41-year-old small business owner tells me – so when the group was seeking a new manager recently, she decided to step up.

The teenager, too, has played an important role in the group. A clip he made, imploring the municipal authority to block a road through a nature reserve during breeding time, influenced the outcome the group's way. After a twelve months of campaigning, the council agreed to an "restricted access" rule between evening and morning from February through to spring. The majority of motorists duly avoided the road.

Additional Species and Difficulties

A few vehicles go by when I'm out on patrol and we discover some victims as a consequence – no amphibians, but three squashed newts. We see one living newt as well, and the youngster is especially excited to see a harvestman, which moves in his hands. Yet despite the team's best efforts to let me see a toad, the local population has obviously settled down for the winter. It seems that I wouldn't have had any better success elsewhere in the country – all the patrol groups I reach out to explain that it's near-impossible at this time of year.

The group expects to help approximately 10,000 adult toads across the road

A message I get from another volunteer, who has kindly made the effort to check for toads in a famous site, thought to be the biggest tracked toad group in the UK, reaches me with the subject line: "None found." However, in late winter, he tells me, the team plans to assist around 10,000 mature amphibians over the street.

Impact and Challenges

How much of a difference can these groups truly achieve? "The reality that volunteers are doing this consistently on cold, damp and unpleasant late nights is quite extraordinary," notes an researcher. "This effort that very much deserves recognition." However, while toad patrols are able to slow the decline, they can't stop it completely – not least because vehicles is just one danger.

Other Dangers

The climate crisis has meant extended spells of drought, which cause the poor environment for some of the creatures that toads consume, such as invertebrates, while warmer ponds have led to an increase of toxic plants, which can be harmful to toads. Warmer cold seasons also lead toads to emerge from their dormancy more frequently, interfering with the energy conservation vital to their life cycle. Habitat destruction – particularly the disappearance 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 their presence." But toads play an important role in the food chain, eating pretty much any invertebrates or small animals they can fit in their mouths and in turn feeding a number of birds and mammals, such as hedgehogs and otters. Enhancing conditions for toads – such as building water habitats, protecting forests and installing amphibian passages – "benefits for a whole bunch of additional wildlife."

Historical Significance

An additional motive to work to preserve toads around is their "important cultural value," adds an specialist. Legends and tales around toads go back {centuries|hundred
