It is Friday night at half past seven, but instead of heading to the pub or watching a film, I've taken a train to a market town in Wiltshire to meet up with local helpers from a amphibian rescue group. These committed people sacrifice their nights to protect the local toad population.

A Worrying Drop in Numbers

The common toad is growing more rare. A recent research led by an amphibian and reptile charity revealed that the British common toad numbers have almost halved since the mid-1980s. Observing a creature that has been a stalwart of the British countryside in decrease is described as "concerning" by experts. Toads "don't need very particular environments" and "should be able to live successfully in most of habitats in the UK," 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 Danger from Traffic

Though the study didn't cover the reasons for the decline, traffic is a major factor. Estimates indicate that 20 tonnes of toads are crushed on British roads annually – in other words, hundreds of thousands. In contrast to frogs, which might be content to mate "if you left out a bucket of water," toads prefer big bodies of water. Their ability to remain away from water for longer than frogs means they can journey farther to reach them – often long distances. They usually follow their ancestral migration routes – it's typical for mature amphibians to return to their natal pond to mate.

Migration Patterns

Fittingly, the first toads start their journey for a partner around February 14th, but others travel as far as spring, until it gets dark and travelling 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 grew up in the area and has been working to save its amphibians since he was a boy, notes that "Their sole purpose: to go and mate." If their route 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.

Toad Patrols Throughout the UK

Finding many of dead toads on local roads "inherently strikes a chord with people," and has resulted in the creation of rescue teams across the UK – 274 groups are officially listed with a national initiative. These groups collect toads and carry them over streets in containers, as well as recording the number of toads they encounter and advocating for other safety solutions, such as road closures and underground wildlife tunnels.

Volunteers usually work during the breeding period, when amphibian movements are more regular. However, this means they can overlook numbers of toadlets, which, having existed as spawn and then tadpoles, exit their water habitats over an unpredictable schedule in late summer. Because of their small stature – just one or two centimetres wide – "they can get obliterated by car traffic." And as being run over "basically turns them into mush," it's harder to collect information on them. At least when adult toads are lost, their remains can be tallied.

Annual Work

Unlike most patrols, one local team, who are in their eighth season of functioning, go out year-round – not nightly, but when conditions are warm and wet, or if someone has posted about a amphibian spotting in their messaging app. When I request to accompany them on patrol, they concede it is "not ideal conditions" – winter dormancy has begun and it's been a dry day – but a few of the helpers willingly accept to patrol their route with me and search for any toads. "Should anyone can find any toads tonight, that pair will find one," says the patrol manager, indicating her teenage child and the experienced member. We've been out for 120 minutes without a glimpse of any amphibians, and now they have scaled a barbed wire fence to inspect beneath some logs.

Community Involvement

The family duo joined the patrol a while back. The youngster loves all things wildlife and has an goal to become a conservationist, so his parent started to search for things they could do together to protect native animals. Now she loves it as much as he does, the middle-aged entrepreneur explains – so when the team was looking for a new manager lately, she decided to step up.

The teenager, too, has played an important role in the organization. A video he made, imploring the local council to block a street through a protected area during migration season, swung the decision the group's way. After a year of lobbying, the authority agreed to an "access-only" restriction between 5pm and 5am from February through to April. Most drivers respected and avoided the road.

Additional Species and Difficulties

Several cars go by when I'm out on patrol and we discover some casualties as a result – no toads, but several crushed salamanders. We spot one live amphibian as well, and the teenager is especially excited to see a harvestman, which moves in his hands. Yet despite the team's best efforts to show me a toad, the local population has obviously settled down for the colder months. It seems that I couldn't have found any more luck elsewhere in the nation – all the patrol groups I contact explain that it's near-impossible 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 made the effort to check for toads in a famous site, thought to be 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 group expects to help around ten thousand adult toads across the road.

Impact and Challenges

How much of a difference can these groups actually make? "The fact that volunteers are performing this consistently on cold, damp and unpleasant evenings is remarkable," notes an expert. "That's something that very much deserves recognition." However, while rescue teams are able to reduce the drop, they can't stop it completely – partly since vehicles is just one danger.

Additional Threats

The global warming has resulted in longer periods of drought, which cause the wrong conditions for some of the animals that toads consume, such as worms and slugs, while higher water temperatures have caused an increase of blue-green algae, which can be harmful to toads. Milder winters also lead toads to emerge from their hibernation more often, disrupting the energy conservation crucial to their existence. Loss of environment – especially the disappearance of big water bodies – is another menace.

Experts are "often concerned about overemphasizing practical benefits on wildlife," however "It's important in just their presence." But toads do have an significant part in the ecosystem, consuming almost any small creatures or tiny organisms they can swallow and in turn sustaining a variety of birds and mammals, such as wildlife. Improving situations for toads – such as creating more ponds, conserving woodland and installing toad tunnels – "benefits for a wide range of additional wildlife."

Cultural Significance

An additional motive to try to keep toads around is their "important cultural value," adds an specialist. Legends and tales around toads go back {centuries|hundred
