It is Friday night at 7:30, but rather than going out or relaxing at home, I've caught a train to a town in the countryside to meet up with local helpers from a toad patrol. These dedicated individuals give up their evenings to safeguard the native amphibian community.

An Alarming Drop in Population

The common toad is becoming increasingly uncommon. A recent study conducted by an wildlife conservation group revealed that the UK toad population have dropped by half since the mid-1980s. Seeing a species that has been a stalwart of the UK landscape in decrease is described as "worrying" by experts. Toads "don't require very particular environments" and "ought to live successfully in the majority of areas in Britain," so if even they are not managing to survive, "it indicates 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 cover the reasons for the decline, cars certainly plays a part. Calculations suggest that 20 tonnes of toads are killed on British roads annually – that is, hundreds of thousands. In contrast to frogs, which would probably be happy to mate "if you left out a small container," toads prefer large ponds. Their capacity to remain away from water for longer than frogs means they can travel further to reach them – often long distances. They tend to follow their ancestral migration routes – it's typical for adult toads to go back to their birth pond to mate.

Breeding Patterns

Fittingly, the initial amphibians begin their quest for a mate around Valentine's day, but some move as far as spring, waiting until it gets dark and moving after sunset. During that time, toads start moving from where they have been overwintering "all pretty much at the same time."

One volunteer, who grew up in the area and has been trying to protect its toad population since he was a child, notes that "Their sole purpose: to go and have an orgy." If their path happens to 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 Throughout the United Kingdom

Seeing hundreds of dead toads on local roads "resonates deeply with people," and has led to the formation of toad patrols throughout the UK – hundreds of organizations are currently registered with a national initiative. These groups pick up toads and carry them across roads in buckets, as well as recording the quantity of toads they find and lobbying for other protection measures, such as road closures and amphibian passages.

Volunteers tend to operate during the migration season, when toad crossings are frequent. However, this implies they can overlook groups of toadlets, which, having been eggs and then juveniles, leave their water habitats over an irregular timetable in the end of summer. Because of their size – just a couple of cm wide – "they can get obliterated by car traffic." And as being hit "basically turns them into mush," it's harder to collect information on them. At least when mature amphibians are killed, their remains can be counted.

Year-Round Efforts

Unlike many groups, a specific volunteer group, who are in their eighth season of operating, go out throughout the year – not every night, but whenever weather are warm and wet, or if someone has posted about a amphibian spotting in their group chat. When I request to accompany them on duty, they concede it is "not ideal conditions" – winter dormancy has started and it's been a arid period – but a few of the helpers gamely agree to patrol their area with me and search for any toads. "Should anyone can find any toads tonight, that pair will find one," says the patrol manager, pointing to 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 wood.

Community Involvement

The mother and son joined the patrol a while back. The teenager adores all things nature-related and has an ambition to become a conservationist, so his mother started to look for activities they could do jointly to help local wildlife. Now she enjoys it as much as he does, the 41-year-old entrepreneur explains – so when the team was seeking a new manager lately, she volunteered for the role.

The teenager, too, has been instrumental in the organization. A clip he made, imploring the municipal authority to close a street through a nature reserve during breeding time, swung the decision the team's way. After a year of lobbying, the authority agreed to an "access-only" rule between 5pm and 5am from late winter through to spring. Most drivers respected and avoided the route.

Other Wildlife and Difficulties

A few cars go past when I'm out on patrol and we discover some casualties as a result – no toads, but three squashed newts. We spot one living newt as well, and the teenager is especially excited to see a harvestman, which moves in his palms. Yet despite the group's best efforts to show me a toad, the local population has obviously gone dormant for the colder months. It appears that I couldn't have found any more luck anywhere else in the nation – all the rescue teams I reach out to clarify that it's near-impossible at this time of year.

They project rescuing nearly 10,000 grown amphibians during migration

One email I receive from another volunteer, who has generously made the effort to check for toads in a noted location, considered the biggest tracked toad population in the UK, arrives in my inbox with the title: "No toads." However, in late winter, he tells me, the team plans to assist approximately 10,000 mature amphibians over the street.

Impact and Limitations

How much of a difference can these organizations truly achieve? "The reality that volunteers are doing this consistently on cold, damp and unpleasant late nights is quite extraordinary," says an researcher. "That's something that very much deserves recognition." However, while toad patrols are able to slow the decline, they cannot prevent it entirely – not least because traffic is just one danger.

Additional Threats

The climate crisis has resulted in extended spells of dry weather, which create the wrong conditions for some of the animals that toads consume, such as worms and slugs, while higher water temperatures have caused an rise of toxic plants, which can be toxic to toads. Milder winters also lead toads to wake up from their hibernation more frequently, interfering with the resource preservation crucial to their existence. Loss of environment – especially the loss of big water bodies – is an additional threat.

Experts are "always a bit worried about overemphasizing practical benefits on wildlife," however "It's important in just having these animals around." But toads do have an important role in the ecosystem, eating almost any invertebrates or small animals they can swallow and in turn feeding a number of predators, such as hedgehogs and otters. Improving conditions for toads – such as building water habitats, protecting forests and constructing toad tunnels – "benefits for a whole bunch of additional wildlife."

Cultural Significance

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