It's a Friday evening at half past seven, but instead of heading to the pub or relaxing at home, I've caught a train to a town in Wiltshire to meet up with local helpers from a toad patrol. These dedicated individuals give up their evenings to safeguard the native amphibian community.

A Worrying Drop in Numbers

The Bufo bufo is becoming increasingly uncommon. A latest study conducted by an amphibian and reptile charity showed that the British common toad numbers have dropped by half since 1985. Seeing a species that has been a stalwart of the UK landscape in decline is described as "worrying" by experts. Toads "don't require very particular environments" and "ought to live quite well in most of areas in the UK," so if even they are struggling to persist, "it indicates that the ecosystem is unbalanced."

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

The Danger from Roads

Though the research didn't examine the causes for the decline, cars certainly plays a part. Estimates indicate that 20 tonnes of toads are killed on UK roads annually – in other words, hundreds of thousands. In contrast to frogs, which would probably be content to mate "with just a small container," toads favor large ponds. Their ability to stay out of water for more time than frogs means they can journey farther to reach them – often long distances. They tend to stick to their ancestral migration routes – it's common for mature amphibians to return to their natal pond to mate.

Breeding Habits

Appropriately enough, the first toads start their journey for a mate around February 14th, but others travel as late as spring, until it gets night and travelling through the night. During that period, toads begin migrating from wherever they have been hibernating "all pretty much at the same time."

One volunteer, who grew up in the region 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 route happens to a road, they could all get run over, and that mating period would be lost – stopping a next generation of toads from being produced.

Rescue Groups Across the United Kingdom

Seeing hundreds of toad carcasses on local roads "inherently strikes a chord with people," and has led to the creation of toad patrols across the UK – hundreds of organizations are officially listed with a countrywide program. These teams pick up toads and transport them across roads in containers, as well as counting the quantity of toads they find and lobbying for other protection measures, such as blocked roads and underground wildlife tunnels.

Patrols usually work during the breeding period, when toad crossings are frequent. However, this means they can overlook numbers of toadlets, which, having been eggs and then tadpoles, exit their water habitats 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 run over "basically turns them into mush," it's harder to get data on them. At least when adult toads are lost, their remains can be tallied.

Year-Round Efforts

Unlike most patrols, one local team, who are in their eighth year of operating, go out throughout the year – not nightly, but when conditions are warm and wet, or if a member has reported about a amphibian spotting in their group chat. When I request to accompany them on patrol, 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 gamely agree to walk up and down their route with me and search for any toads. "If anyone can locate any toads tonight, that pair will spot one," says the group coordinator, 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 logs.

Community Involvement

The family duo joined the patrol a while back. The teenager adores 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 enjoys it as much as he does, the middle-aged entrepreneur explains – so when the group was seeking a fresh coordinator lately, she volunteered for the role.

The youth, too, has played an important role in the group. A clip he made, urging the local council to block a road through a protected area during breeding time, swung the decision the group's way. After a year of lobbying, the council approved an "restricted access" rule between evening and morning from late winter through to April. The majority of motorists duly avoided the route.

Other Wildlife and Difficulties

Several cars go past when I'm out on duty and we find some casualties as a result – no amphibians, 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 hands. Yet despite the group's best efforts to let me see a toad, the native community has obviously gone dormant for the winter. It seems that I wouldn't have had any more luck elsewhere in the nation – all the patrol groups 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

One email I get from a different helper, who has generously taken the trouble to check for toads in a noted location, considered the biggest tracked 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 expects to help approximately ten thousand adult toads across the road.

Effectiveness and Challenges

How much of a difference can these groups truly achieve? "The reality 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 deserves recognition." However, while rescue teams are able to slow the decline, they cannot prevent it entirely – not least because vehicles is just one danger.

Additional Threats

The global warming has meant extended spells of drought, which cause the poor environment for some of the animals that toads eat, such as worms and slugs, while higher water temperatures have led to an increase of blue-green algae, which can be harmful to toads. Warmer cold seasons also lead toads to wake up from their hibernation more often, interfering with the energy conservation vital to their life cycle. Loss of environment – particularly the loss of large ponds – is an additional threat.

Researchers are "always a bit worried about putting too much of a utilitarian spin on wildlife," however "It's important in just having these animals around." But toads play an important role in the food chain, eating almost any invertebrates or tiny organisms they can fit in their mouths and in turn feeding a number of predators, such as hedgehogs and otters. Improving situations for toads – ie building water habitats, conserving woodland and constructing toad tunnels – "benefits for a whole bunch of other species."

Historical Significance

Another reason to try to keep toads present is their "historical significance," notes an expert. Myths and folklore around toads go back {centuries|hundred
