It is a Friday evening at 7:30, but rather than going out or relaxing at home, I've taken a train to a town in the countryside to meet up with volunteers from a toad patrol. These dedicated individuals sacrifice their nights to protect the native amphibian community.

An Alarming Decline in Population

The common toad is becoming increasingly rare. A recent research led by an amphibian and reptile charity showed that the UK toad population have almost halved since the mid-1980s. Observing a species that has been a fixture of the British countryside in decrease is described as "concerning" by researchers. 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 indicates that the ecosystem is unbalanced."

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

The Danger from Roads

Though the study didn't cover the reasons for the decline, cars is a major factor. Estimates suggest that 20 tonnes of toads are killed on UK roads annually – in other words, several hundred thousand. In contrast to frogs, which would probably be happy to mate "if you left out a small container," toads favor large ponds. Their capacity to remain away from water for longer than frogs allows they can travel further to reach them – sometimes long distances. They tend to stick to their traditional paths – it's typical for mature amphibians to return to their natal pond to mate.

Breeding Patterns

Fittingly, the initial amphibians start their journey for a mate around Valentine's day, but some move as late as April, waiting until it gets night and travelling after sunset. During that time, toads begin migrating from where they have been overwintering "all pretty much at the same time."

A local helper, who grew up in the region and has been working to save its toad population since he was a boy, notes that "They've got just one focus: to go and have an orgy." If their path crosses a street, they could all get run over, and that mating period would be lost – stopping a new generation of toads from being born.

Rescue Groups Throughout the United Kingdom

Finding hundreds of dead toads on nearby streets "inherently strikes a chord with people," and has led to the formation of rescue teams throughout the UK – 274 groups are officially listed with a countrywide program. These teams collect toads and carry them over streets in containers, as well as counting the quantity of toads they encounter and lobbying for other safety solutions, such as road closures and amphibian passages.

Patrols tend to operate during the breeding period, when toad crossings are more regular. However, this implies they can overlook numbers of toadlets, which, having existed as eggs and then juveniles, exit 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 "basically turns them into mush," it's more difficult to collect information on them. At least when mature amphibians are killed, their carcasses can be counted.

Year-Round Efforts

In contrast to many groups, a specific volunteer group, who are in their eighth year of functioning, go out throughout the year – not nightly, but when weather are damp, or if a member has posted about a amphibian spotting in their group chat. When I ask to join them on patrol, they admit it is "not a toady night" – toad hibernation season has begun and it's been a arid period – but several of the volunteers willingly accept to patrol their area with me and search for any toads. "If anyone can locate any toads tonight, that pair will find one," says the group coordinator, indicating her 14-year-old son and the experienced member. After for 120 minutes without a glimpse of any amphibians, and now they have climbed over a barbed wire fence to inspect beneath some logs.

Community Participation

The mother and son joined the patrol a year and a half ago. The youngster adores all things wildlife and has an ambition to become a environmentalist, so his parent started to look for things they could do together to protect local wildlife. Now she loves it as much as he does, the middle-aged small business owner tells me – so when the team was seeking a fresh coordinator recently, she decided to step up.

The teenager, too, has been instrumental in the group. A video he created, urging the local council to close a street through a nature reserve during migration season, influenced the outcome the team's way. After a year of lobbying, the authority agreed to an "access-only" restriction between 5pm and 5am from late winter through to April. Most drivers respected and avoided the road.

Additional Species and Difficulties

A few cars go by when I'm out on duty and we discover some casualties as a result – no amphibians, but several crushed salamanders. We see one living newt as well, and the youngster is especially excited to see a harvestman, which moves in his hands. Yet in spite of the group's best efforts to show me a toad, the local population has obviously settled down for the winter. It appears that I wouldn't have had any more luck anywhere else in the nation – all the rescue teams I contact explain that it's very difficult at this time of year.

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

A message 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 informs me, the team plans to assist around 10,000 mature amphibians across the road.

Effectiveness and Challenges

What level of impact can these groups actually make? "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 reduce the drop, they cannot prevent it entirely – partly since traffic is just one danger.

Other Dangers

The global warming has resulted in extended spells of dry weather, which create the wrong conditions for some of the animals that toads eat, such as invertebrates, while higher water temperatures have caused an increase of blue-green algae, which can be toxic to toads. Warmer cold seasons also cause toads to emerge from their hibernation more frequently, interfering with the energy conservation vital to their life cycle. Loss of environment – especially the loss of large ponds – is another menace.

Researchers are "often concerned about overemphasizing practical benefits on biodiversity," but "There is a big value in just having these animals around." But toads play an significant part in the food chain, eating almost any small creatures or tiny organisms they can fit in their mouths and in turn feeding a number of predators, such as hedgehogs and otters. Enhancing conditions for toads – such as building water habitats, protecting forests and constructing amphibian passages – "we'll improve them for a whole bunch of additional wildlife."

Cultural Significance

An additional motive to work to preserve toads present is their "important cultural value," notes an expert. Legends and tales around toads go back {centuries|hundred
