It's Friday evening at 7:30, but instead of heading to the pub or relaxing at home, I've taken a train to a market town in the countryside to meet up with local helpers from a amphibian rescue group. These committed people sacrifice their nights to safeguard the local toad population.

An Alarming Decline in Numbers

The Bufo bufo is becoming increasingly rare. A latest study conducted by an amphibian and reptile charity showed that the British common toad numbers have almost halved since 1985. Seeing a species that has been a fixture of the UK landscape in decrease is described as "worrying" by experts. Toads "don't need very specific conditions" and "ought to live quite well in the majority of habitats in the UK," 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 Roads

Though the research didn't examine the causes for the decline, traffic certainly plays a part. Estimates suggest that 20 tonnes of toads are killed on UK roads annually – that is, several hundred thousand. Unlike frogs, which might be content to mate "if you left out a bucket of water," toads favor big bodies of water. Their capacity to remain away from water for longer than frogs means they can journey farther to reach them – sometimes long distances. They usually follow their ancestral migration routes – it's common for mature amphibians to go back to their natal pond to mate.

Breeding Patterns

Appropriately enough, the first toads start their journey for a mate around Valentine's day, but others travel as late as spring, until it gets dark and travelling after sunset. During that time, toads start moving from wherever they have been overwintering "almost simultaneously."

One volunteer, who grew up in the region and has been working to save its amphibians since he was a child, notes that "They've got just one focus: to go and have an orgy." 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 born.

Toad Patrols Across the UK

Seeing hundreds of dead toads on nearby streets "inherently strikes a chord with people," and has resulted in the formation of rescue teams across the UK – hundreds of organizations are officially listed with a national initiative. These teams pick up toads and transport 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 underground wildlife tunnels.

Volunteers tend to operate during the migration season, when toad crossings are frequent. However, this means they can miss groups of young toads, which, having been spawn and then tadpoles, exit their ponds over an irregular timetable in late summer. Because of their size – just a couple of cm wide – "they can get obliterated by car traffic." And as being hit "essentially crushes them," it's harder to collect information on them. At least when mature amphibians are lost, their remains can be counted.

Annual Work

In contrast to most patrols, a specific volunteer group, who are in their eighth year of operating, go out year-round – not every night, but whenever conditions are damp, or if a member has posted about a amphibian spotting in their messaging app. When I request to accompany them on duty, they concede it is "not ideal conditions" – winter dormancy has begun and it's been a dry day – but several of the volunteers gamely agree to walk up and down their route with me and see what we can find. "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. We've been out for 120 minutes without a single toad sighting, and now they have scaled a wire barrier to check under some wood.

Family Participation

The mother and son became part of the patrol a while back. The youngster adores all things nature-related and has an ambition to become a environmentalist, so his parent started to search for activities they could do jointly to protect local wildlife. Now she loves it as much as he does, the 41-year-old entrepreneur tells me – so when the team was looking for a fresh coordinator recently, she volunteered for the role.

The youth, too, has played an important role in the group. A video he created, imploring the local council to close a street through a protected area during breeding time, swung the decision the team's way. After a year of campaigning, the council agreed to an "access-only" restriction between 5pm and 5am from February through to spring. The majority of motorists respected and avoided the road.

Other Wildlife and Difficulties

Several cars go past when I'm out on patrol and we discover some victims as a result – no amphibians, but three squashed newts. We see one living newt as well, and the youngster is especially excited to see a daddy longlegs, which moves in his hands. Yet despite the group's hardest attempts to let me see a toad, the local population has clearly settled down for the winter. It appears that I couldn't have found any better success elsewhere in the country – all the patrol groups I reach out to clarify that it's very difficult at this time of year.

They project rescuing nearly 10,000 grown amphibians during migration

A message I receive from a different helper, who has generously made the effort to check for toads in a noted location, considered the largest accurately monitored toad group in the UK, arrives in my inbox with the subject line: "None found." However, in February and March, he tells me, the group expects to help around 10,000 adult toads across the road.

Effectiveness and Limitations

How much of a difference can these groups truly achieve? "The reality that people are performing this regularly on cold, damp and unpleasant late nights is remarkable," 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 – partly since traffic is just one danger.

Other Dangers

The global warming has resulted in extended spells of drought, which create 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 toxic to toads. Milder winters also cause toads to emerge from their dormancy more often, disrupting the energy conservation vital to their existence. Loss of environment – particularly the loss of large ponds – 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 ecosystem, eating pretty much any small creatures or tiny organisms they can fit in their mouths and in turn feeding a variety of birds and mammals, such as hedgehogs and otters. Enhancing conditions for toads – such as building water habitats, conserving woodland and constructing 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
