It's Friday night at 7:30, but instead of heading to the pub or watching a film, I've taken a train to a market town in Wiltshire to meet up with volunteers from a amphibian rescue group. These dedicated individuals sacrifice their evenings to safeguard the local toad population.

A Worrying Drop in Population

The Bufo bufo is growing more rare. A recent research conducted by an wildlife conservation group revealed that the British common toad numbers have dropped by half since the mid-1980s. Observing a species that has been a stalwart of the British countryside in decrease is labeled "concerning" by experts. Toads "don't require very particular environments" and "ought to live quite well in the majority of areas in Britain," meaning if even they are not managing to survive, "it kind of suggests that things are not as they should be."

The UK toad population has almost halved since 1985

The Danger from Roads

Though the study didn't examine the causes for the decline, cars is a major factor. Estimates indicate that 20 tons of toads are killed on British roads every year – that is, several hundred thousand. Unlike frogs, which would probably be content to mate "with just a small container," toads prefer large ponds. Their ability to stay out of water for more time than frogs allows they can journey farther to find them – often hundreds of metres. They usually stick to their traditional paths – it's typical for adult toads to return to their natal pond to mate.

Breeding Habits

Appropriately enough, the first toads begin their quest for a mate around Valentine's day, but others travel as late as spring, waiting until it gets dark and moving after sunset. During that period, toads begin migrating from wherever they have been hibernating "almost simultaneously."

A local helper, who grew up in the region and has been working to save its toad population since he was a child, notes that "Their sole purpose: to go and have an orgy." If their route crosses a road, they could be killed by traffic, and that breeding season would never happen – stopping a next generation of toads from being born.

Rescue Groups Throughout the United Kingdom

Finding hundreds of dead toads on local roads "resonates deeply with people," and has resulted in the creation of rescue teams throughout the UK – 274 groups are officially listed with a countrywide program. These teams pick up toads and transport them across roads in containers, as well as counting the number of toads they find and advocating for other protection measures, such as blocked roads and amphibian passages.

Volunteers usually work during the breeding period, when toad crossings are more regular. However, this means they can miss numbers of young toads, which, having been eggs and then tadpoles, exit their ponds over an irregular timetable in late summer. Because of their small stature – just a couple of cm wide – "they can get obliterated by vehicles." And as being run over "basically turns them into mush," it's more difficult to collect information on them. At least when adult toads are lost, their carcasses can be tallied.

Year-Round Efforts

Unlike many groups, a specific volunteer group, who are in their eighth season of functioning, go out throughout the year – not nightly, but whenever weather are warm and wet, or if someone has reported about a amphibian spotting in their messaging app. When I ask to join them on duty, they admit it is "not ideal conditions" – winter dormancy has started and it's been a dry day – but a few of the volunteers willingly accept 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 spot one," says the patrol manager, pointing to her teenage child and the experienced member. We've been out for 120 minutes without a glimpse of any amphibians, and now they have climbed over a barbed wire fence to inspect beneath some wood.

Family Involvement

The family duo joined the group a year and a half ago. The teenager loves all things nature-related and has an goal to become a environmentalist, 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 explains – so when the team was looking for a new manager recently, she decided to step up.

The teenager, too, has played an important role in the organization. A video he created, urging the local council to close a road through a nature reserve during migration season, swung the decision the team's way. After a twelve months of lobbying, the council approved an "restricted access" restriction between evening and morning from late winter through to spring. Most drivers duly avoided the route.

Other Wildlife and Difficulties

A few vehicles go past when I'm out on duty and we find some casualties as a result – no toads, but several crushed salamanders. We spot one live amphibian as well, and the teenager is especially excited to see a daddy longlegs, which moves in his palms. Yet despite the team's hardest attempts to let me see a toad, the native community has clearly settled down for the winter. It appears that I couldn't have found any more luck anywhere else in the nation – 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 kindly made the effort to look for toads in a famous site, thought to be the largest accurately monitored toad population in the UK, reaches me with the subject line: "No toads." However, in February and March, he tells me, the team expects to help around ten thousand adult toads over the street.

Impact and Limitations

How much of a difference can these organizations truly achieve? "The fact that people are doing this consistently on chilly, wet and miserable evenings is remarkable," says an researcher. "That's something that very much should be celebrated." However, while rescue teams are able to slow the decline, they cannot prevent it entirely – partly since traffic is just one danger.

Additional Threats

The global warming has meant extended spells of drought, which create the wrong conditions for some of the creatures that toads eat, such as worms and slugs, while higher water temperatures have led to an rise of toxic plants, which can be harmful to toads. Milder winters also lead toads to wake up from their hibernation more frequently, disrupting the resource preservation vital to their life cycle. Loss of environment – especially the loss of large ponds – is an additional threat.

Experts are "always a bit worried about putting too much of a utilitarian spin on biodiversity," but "It's important in just having these animals around." But toads play an important role in the ecosystem, eating almost any small creatures or tiny organisms they can swallow and in turn feeding a number of predators, such as hedgehogs and otters. Enhancing conditions for toads – such as creating more ponds, protecting forests and installing toad tunnels – "we'll improve them for a whole bunch of other species."

Cultural Importance

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