It is Friday evening at 7:30, but instead of going out or watching a film, I've caught a train to a town in Wiltshire to join local helpers from a toad patrol. These committed people sacrifice their nights to protect the local toad population.

A Worrying Decline in Population

The Bufo bufo is growing more rare. A latest study led by an amphibian and reptile charity showed that the British common toad numbers have almost halved since the mid-1980s. Observing a species that has been a stalwart of the British countryside in decline is described as "concerning" by experts. Toads "don't need very particular environments" and "ought to live successfully in the majority of habitats in Britain," meaning if even they are not managing to survive, "it kind of suggests that things are not as they should be."

The Danger from Traffic

Though the research didn't cover the reasons for the drop, traffic certainly plays a part. Calculations indicate that 20 tons of toads are killed on British roads annually – in other words, several hundred thousand. In contrast to frogs, which might be content to mate "if you left out a bucket of water," toads prefer large ponds. Their capacity to remain away from water for more time than frogs allows they can journey farther to reach them – often long distances. They tend to stick to their traditional paths – it's typical for mature amphibians to go back 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 late as April, until it gets night and travelling after sunset. During that time, toads begin migrating from where they have been hibernating "almost simultaneously."

One volunteer, who grew up in the region and has been trying to protect its toad population since he was a boy, explains that "Their sole purpose: to go and mate." If their route crosses a road, they could all get run over, and that mating period would never happen – stopping a next generation of toads from being produced.

Rescue Groups Throughout the UK

Seeing hundreds of dead toads on nearby streets "resonates deeply with people," and has led to the creation of toad patrols across the UK – hundreds of organizations are officially listed with a national initiative. These teams collect toads and transport them over streets in buckets, as well as recording the quantity of toads they encounter and lobbying for other protection measures, such as road closures and underground wildlife tunnels.

Volunteers usually work during the migration season, when toad crossings are frequent. However, this means they can miss numbers of young toads, which, having been spawn and then tadpoles, leave their ponds over an irregular timetable in late summer. Because of their size – just a couple of cm wide – "they can get obliterated by vehicles." 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 carcasses can be tallied.

Annual Work

In contrast to many groups, one local team, who are in their eighth season of functioning, go out year-round – not nightly, but when conditions are damp, or if a member has posted about a toad sighting in their group chat. When I request to accompany them on patrol, they concede it is "not a toady night" – winter dormancy has started and it's been a arid period – but a few of the helpers gamely agree to walk up and down their route with me and see what we can find. "Should anyone can find any toads tonight, that pair will find one," says the patrol manager, indicating her teenage child and the experienced member. After for two hours without a single toad sighting, and now they have scaled a wire barrier to check under some logs.

Family Participation

The mother and son became part of the patrol a year and a half ago. The teenager loves all things wildlife and has an goal to become a conservationist, so his parent started to search 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 looking for a new manager lately, she volunteered for the role.

The youth, too, has been instrumental in the group. A clip he made, imploring the municipal authority to block a street through a nature reserve during migration season, influenced the outcome the group's way. After a twelve months of lobbying, the council agreed to an "access-only" rule between 5pm and 5am from late winter through to spring. The majority of motorists respected and avoided the road.

Additional Species and Challenges

A few vehicles go by when I'm out on duty and we discover some casualties as a consequence – no toads, but three squashed newts. We spot one live amphibian as well, and the teenager is particularly pleased to see a harvestman, which dances in his palms. Yet in spite of the team's hardest attempts to show me a toad, the local population has clearly gone dormant for the winter. It appears that I wouldn't have had any better success anywhere else in the nation – all the rescue teams I contact clarify that it's very difficult at this time of year.

One email I get from a different helper, who has kindly made the effort to look for toads in a noted location, considered the biggest tracked toad population in the UK, reaches me with the title: "No toads." However, in February and March, he informs me, the group plans to assist approximately 10,000 adult toads over the street.

Effectiveness and Limitations

What level of impact can these organizations actually make? "The reality that people are doing this consistently on cold, damp and unpleasant late nights is quite extraordinary," notes an researcher. "This effort that very much should be celebrated." However, while toad patrols are able to reduce the drop, they can't stop it completely – not least because vehicles is not the only threat.

Other Dangers

The global warming 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 warmer ponds have caused an rise of toxic plants, which can be harmful to toads. Milder winters also lead toads to wake up from their dormancy more frequently, disrupting the energy conservation crucial to their existence. Loss of environment – particularly the disappearance of large ponds – is an additional threat.

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 significant part in the food chain, consuming almost any small creatures or tiny organisms they can swallow and in turn feeding a number of predators, such as wildlife. Improving conditions for toads – such as building water habitats, protecting forests and installing toad tunnels – "we'll improve them for a whole bunch of additional wildlife."

Historical Significance

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