It's a Friday evening at half past seven, but instead of going out or watching a film, I've caught a train to a market town in Wiltshire to join local helpers from a amphibian rescue group. These committed people sacrifice their evenings to protect the local toad population.

A Worrying Drop in Numbers

The common toad is growing more uncommon. A recent research led by an amphibian and reptile charity revealed that the British common toad numbers have almost halved since 1985. Seeing a species that has been a fixture of the UK landscape in decline is described as "worrying" by researchers. Toads "don't need very particular environments" and "should be able to live successfully in the majority of areas in Britain," so if even they are not managing to survive, "it kind of suggests that the ecosystem is unbalanced."

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

The Danger from Traffic

Though the study didn't cover the causes for the decline, traffic is a major factor. Estimates indicate that 20 tonnes of toads are crushed on British roads every year – in other words, hundreds of thousands. In contrast to frogs, which might be content to mate "with just a bucket of water," toads prefer large ponds. Their ability to stay out of water for more time than frogs allows they can travel further to reach them – often hundreds of metres. They usually follow their traditional paths – it's typical for mature amphibians to go back to their natal pond to mate.

Breeding Habits

Fittingly, the first toads begin their quest for a partner around Valentine's day, but others travel as far as spring, waiting until it gets night and moving through the night. During that period, toads start moving from where they have been overwintering "all pretty much at the same time."

A local helper, who grew up in the region and has been working to save its toad population since he was a boy, explains that "They've got just one focus: to go and have an orgy." If their path crosses a street, they could be killed by traffic, and that mating period would never happen – stopping a next generation of toads from being produced.

Rescue Groups Across the United Kingdom

Seeing hundreds of dead toads on nearby streets "inherently strikes a chord with people," and has led to the formation of toad patrols across the UK – hundreds of organizations are officially listed with a countrywide program. These teams pick up toads and carry them over streets in buckets, as well as recording the number of toads they encounter and advocating for other protection measures, such as road closures and underground wildlife tunnels.

Patrols tend to operate during the migration season, when amphibian movements are frequent. However, this means they can overlook numbers of young toads, which, having been eggs and then tadpoles, leave their ponds over an irregular timetable in late summer. Because of their size – just one or two centimetres wide – "they are destroyed by car traffic." And as being run over "essentially crushes them," it's more difficult to collect information on them. At least when mature amphibians are lost, their carcasses can be counted.

Year-Round Work

In contrast to many groups, one local team, who are in their eighth season 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 group chat. When I ask to join them on duty, they concede it is "not ideal conditions" – winter dormancy has started and it's been a dry day – but a few of the helpers gamely agree to patrol their area with me and search for any toads. "If anyone can locate any toads tonight, that pair will find one," says the group coordinator, indicating her 14-year-old son and the experienced member. We've been out for two hours without a glimpse of any amphibians, and now they have climbed over a wire barrier to inspect beneath some logs.

Family Participation

The family duo became part of the group a while back. The youngster loves all things nature-related and has an ambition to become a conservationist, so his mother started to look for things they could do jointly to help 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 fresh coordinator recently, she decided to step up.

The teenager, too, has been instrumental in the group. A video he made, imploring the municipal authority to block a road through a nature reserve during breeding time, swung the decision the group's way. After a twelve months of lobbying, the council approved an "access-only" rule between evening and morning from late winter through to spring. The majority of motorists respected and avoided the road.

Other Wildlife and Challenges

A few cars go past when I'm out on patrol and we find some casualties as a consequence – no toads, but several crushed salamanders. We see one live amphibian as well, and the youngster is especially excited to see a harvestman, which moves in his hands. Yet in spite of the team's best efforts to show me a toad, the native community has clearly settled down for the winter. It seems that I wouldn't have had any more luck anywhere else in the country – all the rescue teams I reach out to clarify that it's near-impossible at this time of year.

This team anticipates assisting around ten thousand mature toads over the street

A message 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 group in the UK, reaches me with the title: "No toads." However, in February and March, he informs me, the team expects to help around ten thousand mature amphibians over the street.

Effectiveness and Limitations

How much of a difference can these groups truly achieve? "The fact that volunteers are doing this consistently on cold, damp and unpleasant late nights is quite extraordinary," says an expert. "That's something that very much deserves recognition." However, while toad patrols are able to reduce the drop, they cannot prevent it entirely – not least because traffic is not the only threat.

Additional Threats

The global warming has resulted in extended spells of dry weather, which create the poor environment for some of the creatures that toads consume, such as invertebrates, while higher water temperatures have led to an rise of blue-green algae, which can be harmful to toads. Milder winters also lead toads to wake up from their dormancy more often, disrupting the energy conservation vital to their life cycle. Habitat destruction – particularly the loss of big water bodies – is another menace.

Experts are "always a bit worried about overemphasizing practical benefits on biodiversity," but "It's important in just their presence." But toads play an significant part in the food chain, eating almost any small creatures or tiny organisms 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 creating more ponds, conserving woodland and installing amphibian passages – "benefits for a whole bunch of additional wildlife."

Historical Importance

An additional motive to try to keep toads around is their "important cultural value," notes an expert. Myths and folklore around toads date back {centuries|hundred
