It is Friday night at half past seven, but rather than going out or watching a film, I've taken a train to a town in Wiltshire to join local helpers from a amphibian rescue group. These committed people sacrifice their evenings to safeguard the native amphibian community.

A Worrying Decline in Population

The Bufo bufo is growing more rare. A latest study led by an wildlife conservation group showed that the British common toad numbers have almost halved since the mid-1980s. Observing a creature that has been a fixture of the UK landscape in decline is labeled "worrying" by experts. Toads "don't require very particular environments" and "ought to live quite well in most of areas in Britain," so if even they are struggling to persist, "it indicates that the ecosystem is unbalanced."

The Threat from Roads

Though the study didn't examine the reasons for the drop, cars is a major factor. Calculations indicate that 20 tonnes of toads are killed on British roads annually – in other words, several hundred thousand. Unlike frogs, which would probably be happy to mate "if you left out a bucket of water," toads prefer large ponds. Their ability to remain away from water for more time than frogs allows they can travel further to find them – sometimes long distances. They tend to follow their ancestral migration routes – it's typical for mature amphibians to go back to their natal pond to mate.

Migration Habits

Fittingly, the initial amphibians begin their quest for a mate around February 14th, but others travel as far as April, until it gets night and travelling after sunset. During that period, toads start moving from wherever they have been overwintering "almost simultaneously."

A local helper, who was raised in the region and has been working to save its toad population since he was a boy, explains that "Their sole purpose: to go and mate." If their path crosses a road, they could all get run over, and that mating period would never happen – preventing a new generation of toads from being produced.

Rescue Groups Across the UK

Seeing hundreds of dead toads on nearby streets "resonates deeply with people," and has resulted in the creation of rescue teams across the UK – hundreds of organizations are currently registered with a national initiative. These groups pick up toads and transport them across roads in containers, as well as recording the number of toads they encounter and advocating for other safety solutions, such as blocked roads and amphibian passages.

Volunteers tend to operate during the migration season, when amphibian movements are frequent. However, this implies they can overlook numbers of young toads, which, having been spawn and then tadpoles, exit their water habitats over an irregular timetable in late summer. Because of their size – just a couple of cm wide – "they are destroyed 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 carcasses can be counted.

Annual Work

In contrast to most patrols, one local team, who are in their eighth season of operating, go out year-round – not every night, but whenever weather are warm and wet, or if someone has reported about a toad sighting in their group chat. When I ask to join them on duty, they admit it is "not a toady night" – winter dormancy has started and it's been a dry day – but several of the helpers gamely agree to walk up and down their route with me and search for any toads. "If anyone can find any toads tonight, that pair will find one," says the group coordinator, pointing to her 14-year-old son and the longtime volunteer. After for 120 minutes without a glimpse of any amphibians, and now they have scaled a barbed wire fence to inspect beneath some logs.

Family Participation

The family duo became part of the group a while back. The teenager adores all things nature-related and has an goal to become a environmentalist, so his mother started to look for activities they could do jointly to help local wildlife. Now she loves it as much as he does, the 41-year-old entrepreneur tells me – so when the team was seeking a new manager recently, she volunteered for the role.

The youth, too, has played an important role in the organization. A clip he made, imploring the municipal authority to close a street through a protected area during breeding time, swung the decision the group's way. After a year of campaigning, the authority agreed to an "access-only" restriction between evening and morning from February through to spring. The majority of motorists duly avoided the route.

Other Wildlife and Difficulties

A few vehicles go past when I'm out on duty and we discover some victims as a result – no amphibians, but three squashed newts. We spot one live amphibian as well, and the teenager is especially excited to see a daddy longlegs, which dances in his hands. Yet in spite of the group's best efforts to show me a toad, the native community has obviously settled down for the winter. It seems that I wouldn't have had any more luck anywhere else in the nation – all the rescue teams I reach out to explain that it's near-impossible at this time of year.

One email I get from a different helper, who has generously taken the trouble to look for toads in a noted location, thought to be the biggest tracked toad group in the UK, arrives in my inbox with the subject line: "No toads." However, in late winter, he tells me, the group expects to help around ten thousand adult toads over the street.

Effectiveness and Limitations

How much of a difference can these organizations actually make? "The fact that people are performing this regularly on cold, damp and unpleasant evenings 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 can't stop it completely – not least because vehicles is not the only threat.

Additional Threats

The global warming has meant extended spells of dry weather, which cause the poor environment for some of the animals that toads eat, such as invertebrates, while higher water temperatures have caused an rise of toxic plants, which can be harmful to toads. Warmer cold seasons also lead toads to wake up from their hibernation more often, interfering with the energy conservation vital to their existence. Habitat destruction – especially the loss of large ponds – is another menace.

Experts are "often concerned about overemphasizing practical benefits on wildlife," but "It's important in just their presence." But toads play an significant part in the ecosystem, consuming pretty much any invertebrates or small animals they can fit in their mouths and in turn feeding a variety of birds and mammals, such as wildlife. Improving conditions for toads – such as building water habitats, conserving woodland and installing amphibian passages – "benefits for a wide range of other species."

Historical Importance

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