It is a Friday evening at half past seven, but instead of going out or watching a film, I've caught a train to a town in the countryside to join volunteers from a toad patrol. These committed people give up their nights to safeguard the native amphibian community.

A Worrying Drop in Numbers

The Bufo bufo is becoming increasingly rare. A recent study conducted by an wildlife conservation group showed that the British common toad numbers have dropped by half since 1985. Seeing a species that has been a stalwart of the British countryside in decrease is described as "worrying" by researchers. Toads "don't need very specific conditions" and "ought to live successfully in the majority of areas in the UK," meaning if even they are not managing to survive, "it kind of suggests that things are not as they should be."

The Danger from Roads

Though the study didn't cover the reasons for the decline, cars certainly plays a part. Calculations indicate that 20 tonnes of toads are crushed on British roads annually – that is, hundreds of thousands. In contrast to frogs, which would probably be happy to mate "with just a small container," toads favor big bodies of water. Their ability to remain away from water for more time than frogs allows they can travel further to reach them – sometimes long distances. They usually follow their ancestral migration routes – it's typical for adult toads to return to their birth pond to mate.

Breeding Habits

Fittingly, the initial amphibians start their journey for a partner around February 14th, but others travel as far as spring, until it gets dark and moving after sunset. During that period, toads start moving from where they have been overwintering "almost simultaneously."

One volunteer, who grew up in the area and has been working to save its amphibians since he was a child, explains that "Their sole purpose: to go and mate." If their route happens to a road, they could be killed by traffic, and that mating period would be lost – stopping a next generation of toads from being born.

Rescue Groups Across the United Kingdom

Seeing many of toad carcasses on local roads "resonates deeply with people," and has resulted in the formation of rescue teams throughout the UK – hundreds of organizations are officially listed with a national initiative. These groups collect toads and transport them across roads in containers, as well as counting the quantity of toads they find and advocating for other safety solutions, such as blocked roads and amphibian passages.

Volunteers usually work during the breeding period, when amphibian movements are frequent. However, this means they can miss groups of young toads, which, having been spawn and then juveniles, exit their water habitats over an unpredictable schedule in the end of summer. Because of their size – just one or two centimetres wide – "they can get obliterated 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 lost, their carcasses can be tallied.

Annual Efforts

In contrast to many groups, one local team, who are in their eighth year of functioning, go out year-round – not nightly, but whenever weather are damp, or if a member has reported about a toad sighting in their messaging app. When I request to accompany them on duty, they admit it is "not a toady night" – winter dormancy has begun and it's been a dry day – but a few of the helpers gamely agree to walk up and down their area with me and search for any toads. "If anyone can find any toads tonight, those two will spot one," says the group coordinator, 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 check under some wood.

Family Involvement

The mother and son joined the group a year and a half ago. The youngster adores all things wildlife and has an goal to become a conservationist, so his parent started to look for things they could do together to protect native animals. Now she loves it as much as he does, the middle-aged small business owner tells me – so when the team was seeking a fresh coordinator recently, she decided to step up.

The teenager, too, has been instrumental in the organization. A clip he made, urging the municipal authority to close a road through a protected area during migration season, swung the decision the team's way. After a year of campaigning, the authority approved an "access-only" restriction between 5pm and 5am from late winter through to spring. The majority of motorists duly avoided the road.

Additional Species and Difficulties

Several cars go past when I'm out on duty and we discover some casualties as a result – no amphibians, but three squashed newts. We see one live amphibian as well, and the teenager is especially excited 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 anywhere else in the country – all the rescue teams I contact clarify that it's near-impossible at this time of year.

A message I receive from a different helper, who has kindly made the effort to check for toads in a famous site, thought to be the largest accurately monitored toad group in the UK, arrives in my inbox with the title: "No toads." However, in late winter, he informs me, the team expects to help around ten thousand mature amphibians across the road.

Effectiveness and Limitations

How much of a difference can these organizations truly achieve? "The reality that people are doing this regularly on cold, damp and unpleasant late nights is remarkable," notes an expert. "This effort that very much deserves recognition." However, while toad patrols are able to reduce the drop, they cannot prevent it entirely – not least because vehicles is not the only threat.

Other Dangers

The climate crisis has meant longer periods of dry weather, which create the poor environment for some of the animals that toads consume, such as worms and slugs, while higher water temperatures have caused an increase of blue-green algae, which can be toxic to toads. Milder winters also lead toads to wake up from their dormancy more often, disrupting the resource preservation vital to their existence. Loss of environment – especially the disappearance of big water bodies – is another menace.

Researchers are "always a bit worried about putting too much of a utilitarian spin on biodiversity," but "It's important in just their presence." But toads play an important role in the ecosystem, consuming pretty much any invertebrates or small animals they can swallow and in turn feeding a number of birds and mammals, such as hedgehogs and otters. Enhancing situations for toads – ie creating more ponds, protecting forests and installing toad tunnels – "we'll improve them for a wide range of other species."

Cultural Importance

Another reason to work to preserve toads present is their "important cultural value," notes an expert. Legends and tales around toads go back {centuries|hundred
