It is Friday night at half past seven, but rather than going out or watching a film, I've caught a train to a market town in Wiltshire to meet up with local helpers from a amphibian rescue group. These committed people give up their evenings to protect the native amphibian community.

An Alarming Decline in Population

The Bufo bufo is growing more uncommon. A recent study conducted by an wildlife conservation group revealed that the British common toad numbers have dropped by half since the mid-1980s. Observing a creature that has been a stalwart of the UK landscape in decline is described as "concerning" by experts. Toads "don't require very specific conditions" and "should be able to live quite well in most of habitats in Britain," meaning if even they are not managing to survive, "it kind of suggests that the ecosystem is unbalanced."

Since 1985, Britain's toad numbers have nearly been cut in half

The Threat from Roads

Though the research didn't cover the causes for the decline, cars certainly plays a part. Estimates suggest that 20 tons of toads are killed on UK roads annually – in other words, several hundred thousand. Unlike frogs, which might be happy to mate "if you left out a small container," toads prefer large ponds. Their ability to stay out of water for more time than frogs allows they can travel further to find them – sometimes hundreds of metres. They tend to stick to their traditional paths – it's common for adult toads to return to their birth pond to mate.

Breeding Patterns

Appropriately enough, the first toads start their journey for a mate around Valentine's day, but others travel as far as spring, until it gets dark and moving through the night. During that period, toads begin migrating from wherever they have been overwintering "all pretty much at the same time."

One volunteer, who was raised in the area and has been trying to protect its toad population since he was a child, notes that "They've got just one focus: to go and mate." If their path happens to a street, they could all get run over, and that mating period would be lost – stopping a next generation of toads from being born.

Toad Patrols Across the United Kingdom

Seeing many of toad carcasses on local roads "inherently strikes a chord with people," and has led to the formation of rescue teams throughout the UK – 274 groups are currently registered with a national initiative. These groups pick up toads and carry them across roads in containers, as well as recording the quantity of toads they encounter and advocating for other safety solutions, such as blocked roads and underground wildlife tunnels.

Patrols usually work during the migration season, when toad crossings are frequent. However, this implies they can overlook numbers of toadlets, which, having been spawn and then tadpoles, leave their ponds over an irregular timetable in late summer. Because of their small stature – just one or two centimetres wide – "they can get obliterated by vehicles." And as being run over "essentially crushes them," it's harder to collect information on them. At least when mature amphibians are killed, their carcasses can be tallied.

Annual Efforts

Unlike many groups, one local team, who are in their eighth year 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 group chat. When I ask to join them on patrol, they admit it is "not a toady night" – winter dormancy has started and it's been a arid period – but a few of the volunteers 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 group coordinator, indicating her 14-year-old son and the longtime volunteer. After for 120 minutes without a single toad sighting, and now they have scaled a barbed wire fence to check under some logs.

Community Participation

The family duo became part of the patrol a year and a half ago. The teenager loves all things wildlife and has an ambition to become a conservationist, so his parent started to look for things they could do together to help local wildlife. Now she enjoys it as much as he does, the 41-year-old small business owner explains – so when the team was looking for a fresh coordinator lately, she volunteered for the role.

The teenager, too, has played an important role in the organization. A video he made, imploring the municipal authority to close a road through a nature reserve during migration season, influenced the outcome the group's way. After a year of campaigning, the council approved an "access-only" restriction between evening and morning from late winter through to spring. The majority of motorists duly avoided the road.

Other Wildlife and Difficulties

Several vehicles go by when I'm out on duty and we find some victims as a consequence – no toads, but several crushed salamanders. We see one live amphibian as well, and the teenager is especially excited to see a harvestman, which moves in his hands. Yet in spite of the team's best efforts to let me see a toad, the native community has obviously settled down for the winter. It appears that I couldn't have found any more luck anywhere else in the country – all the rescue teams I reach out to explain that it's very difficult at this time of year.

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

A message I receive from a different helper, who has kindly taken the trouble to look for toads in a famous site, thought to be the largest accurately monitored toad population in the UK, reaches me with the title: "No toads." However, in February and March, he informs me, the group expects to help approximately ten thousand mature amphibians across the road.

Effectiveness and Limitations

How much of a difference can these organizations truly achieve? "The fact that people are performing this consistently on chilly, wet and miserable late nights is remarkable," says an researcher. "This effort that very much deserves recognition." However, while rescue teams are able to reduce the drop, they cannot prevent it entirely – not least because vehicles is not the only threat.

Additional Threats

The climate crisis has resulted in extended spells of dry weather, which create the poor environment for some of the creatures that toads eat, such as worms and slugs, while warmer ponds have led to an rise of toxic plants, which can be toxic to toads. Milder winters also cause toads to wake up from their dormancy more often, interfering with the resource preservation crucial to their life cycle. Habitat destruction – especially the loss of big water bodies – is an additional threat.

Researchers are "often concerned about putting too much of a utilitarian spin on biodiversity," however "There is a big value in just having these animals around." But toads do have an important role in the ecosystem, eating almost any small creatures or tiny organisms they can swallow and in turn sustaining a variety of birds and mammals, such as hedgehogs and otters. Improving conditions for toads – ie creating more ponds, protecting forests and installing toad tunnels – "we'll improve them for a wide range of other species."

Cultural Significance

Another reason to work to preserve toads around is their "historical significance," adds an expert. Myths and folklore around toads date back {centuries|hundred
