It's Friday night at half past seven, but rather than going out or relaxing at home, I've caught a train to a town in Wiltshire to join local helpers from a toad patrol. These committed people give up their evenings to safeguard the local toad population.

An Alarming Drop in Numbers

The Bufo bufo is becoming increasingly rare. A latest study conducted by an amphibian and reptile charity revealed that the British common toad numbers have dropped by half since the mid-1980s. Observing a creature that has been a fixture of the British countryside in decrease is described as "concerning" by researchers. Toads "don't need very particular environments" and "should be able to live quite well in the majority of habitats in the UK," so if even they are struggling to persist, "it indicates that things are not as they should be."

The UK toad population has almost halved since 1985

The Danger from Roads

Though the research didn't examine the reasons for the decline, cars certainly plays a part. Calculations indicate that 20 tons of toads are crushed on UK roads every year – that is, hundreds of thousands. In contrast to frogs, which might be happy to mate "with just a small container," toads prefer big bodies of water. Their ability to remain away from water for longer than frogs allows they can travel further to find them – sometimes hundreds of metres. They tend to stick to their ancestral migration routes – it's common for adult toads to return to their natal pond to mate.

Migration Habits

Appropriately enough, the first toads begin their quest for a mate around Valentine's day, but some move as far as April, waiting until it gets night and moving through the night. During that time, toads begin migrating from wherever they have been overwintering "all pretty much at the same time."

A local helper, who was raised in the region and has been trying to protect its amphibians since he was a boy, notes that "They've got just one focus: to go and have an orgy." If their route happens to a street, they could all get run over, and that mating period would be lost – stopping a new generation of toads from being produced.

Rescue Groups Across the UK

Seeing many of dead toads on local roads "resonates deeply with people," and has led to the formation of toad patrols across the UK – 274 groups are officially listed with a countrywide program. These teams pick up toads and carry them over streets in buckets, as well as recording the quantity of toads they find and lobbying for other protection measures, such as blocked roads and underground wildlife tunnels.

Volunteers tend to operate during the breeding period, when toad crossings are more regular. However, this means they can overlook numbers of toadlets, which, having been spawn and then juveniles, leave their water habitats over an unpredictable schedule in late summer. Because of their size – just one or two centimetres wide – "they are destroyed by vehicles." And as being hit "basically turns them into mush," it's more difficult to collect information on them. At least when adult toads are killed, their remains can be counted.

Annual Work

Unlike most patrols, one local team, who are in their eighth season of operating, go out year-round – not nightly, but whenever conditions are warm and wet, or if someone has reported about a toad sighting in their messaging app. When I ask to join them on duty, they concede it is "not a toady night" – winter dormancy has begun and it's been a arid period – but a few of the volunteers willingly accept to patrol their area with me and search for any toads. "If anyone can find any toads tonight, that pair will find one," says the patrol manager, indicating her teenage child and the experienced member. After for 120 minutes without a single toad sighting, and now they have climbed over a barbed wire fence to check under some wood.

Family Involvement

The mother and son became part of the group a while back. The youngster adores all things nature-related and has an goal to become a conservationist, so his parent started to look for activities they could do jointly to help local wildlife. Now she enjoys it as much as he does, the 41-year-old small business owner tells me – so when the group was seeking a new manager lately, she volunteered for the role.

The youth, too, has played an important role in the group. A video he created, urging the local council to block a road through a protected area during migration season, swung the decision the group's way. After a twelve months of campaigning, the authority approved an "restricted access" rule between evening and morning from February through to spring. The majority of motorists duly avoided the road.

Additional Species and Challenges

A few vehicles go past when I'm out on patrol and we find some casualties as a consequence – no amphibians, but several crushed salamanders. We spot 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 best efforts to show me a toad, the native community has obviously gone dormant for the winter. It seems that I couldn't have found any better success anywhere else in the country – all the rescue teams I contact clarify that it's very difficult at this time of year.

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

One email I get from another volunteer, who has generously taken the trouble to check for toads in a famous site, thought to be the largest accurately monitored toad group in the UK, arrives in my inbox with the subject line: "No toads." However, in February and March, he tells me, the team plans to assist around 10,000 adult toads over the street.

Effectiveness and Challenges

What level of impact can these groups actually make? "The fact that volunteers are doing this regularly on cold, damp and unpleasant evenings is quite extraordinary," notes an expert. "This effort that very much should be celebrated." However, while rescue teams are able to slow the decline, they can't stop it completely – partly since vehicles is just one danger.

Additional Threats

The global warming has resulted in extended spells of drought, which cause the wrong conditions for some of the creatures that toads consume, 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 lead toads to emerge from their hibernation more frequently, disrupting the energy conservation vital to their existence. Habitat destruction – especially the disappearance of large ponds – is another menace.

Researchers are "often concerned 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 food chain, consuming almost any small creatures or small animals they can fit in their mouths and in turn sustaining a number of predators, such as hedgehogs and otters. Enhancing conditions for toads – such as creating more ponds, protecting forests and installing toad tunnels – "benefits for a wide range of additional wildlife."

Cultural Significance

An additional motive to work to preserve toads around is their "historical significance," notes an specialist. Legends and tales around toads go back {centuries|hundred
