It is Friday evening at half past seven, but instead of going out or watching a film, I've taken a train to a market town in Wiltshire to meet up with volunteers from a toad patrol. These committed people sacrifice their nights to safeguard the native amphibian community.

A Worrying Decline in Population

The Bufo bufo is growing more uncommon. A latest study led by an wildlife conservation group showed 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 decrease is described as "worrying" by experts. Toads "don't require very particular environments" and "ought to live quite well in most of habitats in Britain," meaning if even they are struggling to persist, "it kind of suggests that things are not as they should be."

Toad populations across the UK have declined by almost 50% since the 1980s

The Threat from Traffic

Though the research didn't cover the causes for the drop, cars certainly plays a part. Estimates suggest that 20 tons of toads are crushed on UK roads annually – in other words, several hundred thousand. Unlike frogs, which would probably be content to mate "with just a bucket of water," toads favor big bodies of water. Their ability to remain away from water for longer than frogs allows they can travel further to reach them – sometimes long distances. They tend to follow their traditional paths – it's common for adult toads to go back to their birth pond to mate.

Migration Patterns

Appropriately enough, the first toads begin their quest for a partner around Valentine's day, but others travel as far as April, until it gets night and moving after sunset. During that period, toads start moving from where they have been hibernating "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 "Their sole purpose: to go and mate." If their route happens to a road, they could all get run over, and that breeding season would be lost – stopping a new generation of toads from being produced.

Toad Patrols Throughout the UK

Finding hundreds of dead toads on nearby streets "inherently strikes a chord with people," and has led to the creation of rescue teams throughout the UK – 274 groups are officially listed with a national initiative. These groups pick up toads and carry 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.

Patrols usually work during the breeding period, when toad crossings are frequent. However, this means they can miss groups of toadlets, which, having existed as eggs 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 more difficult to collect information on them. At least when mature amphibians are killed, their remains can be tallied.

Annual Work

In contrast to many groups, one local team, who are in their eighth year of functioning, go out throughout the year – not nightly, but whenever weather are damp, or if a member has reported about a amphibian spotting in their messaging app. 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 arid period – but a few of the volunteers willingly accept to walk up and down their area with me and see what we can find. "If anyone can find any toads tonight, those two will spot one," says the patrol manager, indicating her 14-year-old son and the longtime volunteer. We've been out for two hours without a single toad sighting, and now they have climbed over a wire barrier to inspect beneath some wood.

Family Participation

The mother and son became part of the patrol a year and a half ago. The teenager adores all things wildlife and has an goal to become a environmentalist, so his parent started to search for things they could do together to help native animals. Now she enjoys it as much as he does, the 41-year-old small business owner explains – so when the team was seeking a fresh coordinator lately, she volunteered for the role.

The youth, too, has been instrumental in the group. A video he created, urging the municipal authority to block a road through a nature reserve during breeding time, influenced the outcome the team's way. After a year of campaigning, the authority agreed to an "restricted access" restriction between evening and morning from late winter through to spring. The majority of motorists duly avoided the route.

Additional Species and Difficulties

A few vehicles go past when I'm out on patrol and we discover some victims as a result – no toads, but several crushed salamanders. We spot one living newt as well, and the teenager is particularly pleased to see a harvestman, which moves in his palms. Yet despite the team's best efforts to let me see a toad, the native community has obviously gone dormant for the colder months. It appears that I wouldn't have had any better success elsewhere in the country – all the rescue teams I contact explain that it's very difficult at this season.

The group expects to help approximately 10,000 adult toads across the road

One email I receive from another volunteer, who has kindly made the effort to look for toads in a famous site, considered the largest accurately monitored toad population in the UK, arrives in my inbox with the subject line: "No toads." However, in February and March, he tells me, the team expects to help approximately 10,000 mature amphibians over the street.

Effectiveness and Limitations

What level of impact can these groups truly achieve? "The fact that volunteers are performing this regularly on chilly, wet and miserable late nights is quite extraordinary," says an expert. "That's something that very much should be celebrated." However, while toad patrols are able to reduce the drop, they cannot prevent it entirely – partly since vehicles is just one danger.

Other Dangers

The climate crisis has resulted in longer periods of dry weather, which cause the wrong conditions for some of the animals that toads consume, such as invertebrates, while higher water temperatures have caused an increase of toxic plants, which can be toxic to toads. Milder winters also lead toads to emerge from their hibernation more often, interfering with the energy conservation crucial to their life cycle. Habitat destruction – particularly the loss of big water bodies – is another menace.

Researchers are "always a bit worried about putting too much of a utilitarian spin on biodiversity," however "There is a big value in just having these animals around." But toads play an important role in the ecosystem, eating pretty much any small creatures or small animals they can fit in their mouths and in turn sustaining a variety of predators, such as hedgehogs and otters. Enhancing conditions for toads – such as building water habitats, conserving woodland and installing amphibian passages – "we'll improve them for a wide range of additional wildlife."

Historical Importance

Another reason to work to preserve toads around is their "important cultural value," adds an expert. Legends and tales around toads go back {centuries|hundred
