It is a Friday evening at half past seven, but instead of going out or relaxing at home, I've caught a train to a market town in Wiltshire to join local helpers from a toad patrol. These committed people give up their evenings to protect the local toad population.

A Worrying Drop in Numbers

The Bufo bufo is growing more uncommon. A recent study led by an wildlife conservation group revealed that the UK toad population have almost halved since 1985. Seeing a creature that has been a fixture of the UK landscape in decrease is labeled "concerning" by experts. Toads "don't require very particular environments" and "ought to live quite well in the majority of habitats in Britain," so if even they are not managing to survive, "it indicates that things are not as they should be."

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

The Threat from Traffic

Though the study didn't cover the causes for the decline, cars certainly plays a part. Estimates suggest that 20 tonnes of toads are killed on UK roads every year – that is, several hundred thousand. Unlike frogs, which would probably be happy to mate "with just a small container," toads prefer large ponds. Their ability to remain away from water for longer than frogs means they can journey farther to find them – often long distances. They usually stick to their traditional paths – it's common for adult toads to go back to their natal pond to mate.

Breeding Habits

Fittingly, the first toads begin their quest for a mate around Valentine's day, but some move as late as April, waiting until it gets dark and travelling through the night. During that period, toads start moving from where they have been hibernating "all pretty much at the same time."

One volunteer, who grew up in the area and has been trying to protect its amphibians since he was a boy, explains that "They've got just one focus: to go and have an orgy." If their path happens to a street, they could be killed by traffic, and that breeding season would never happen – stopping a new generation of toads from being born.

Toad Patrols Across the UK

Finding many of dead toads on nearby streets "resonates deeply 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 pick up toads and carry them over streets in containers, as well as counting the number of toads they encounter and lobbying for other safety solutions, such as road closures and underground wildlife tunnels.

Volunteers usually work during the migration season, when amphibian movements are more regular. However, this implies they can miss groups of toadlets, which, having been spawn and then tadpoles, leave 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 get data on them. At least when mature amphibians are lost, their remains can be tallied.

Annual Work

In contrast to most patrols, one local team, who are in their eighth season of functioning, go out year-round – not nightly, but whenever weather are damp, or if a member has posted about a toad sighting in their messaging app. When I ask to join them on duty, they admit it is "not ideal conditions" – winter dormancy has started and it's been a arid period – but a few of the volunteers willingly accept to patrol their area with me and see what we can find. "If anyone can find any toads tonight, that pair will spot one," says the group coordinator, pointing to her teenage child and the experienced member. We've been out for two hours without a glimpse of any amphibians, and now they have climbed over a wire barrier to inspect beneath some wood.

Family Involvement

The mother and son joined the patrol a year and a half ago. The youngster loves all things wildlife and has an ambition to become a conservationist, so his parent started to look for activities they could do jointly to help 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 lately, she decided to step up.

The teenager, too, has played an important role in the group. A video he made, urging the local council to block a street through a protected area during migration season, swung the decision the team's way. After a twelve months of campaigning, the authority agreed to an "restricted access" rule between 5pm and 5am from late winter through to April. The majority of motorists respected and avoided the route.

Other Wildlife and Difficulties

Several vehicles 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 live amphibian as well, and the youngster is particularly pleased to see a daddy longlegs, which dances in his hands. Yet despite the group's best efforts to show me a toad, the native community has clearly settled down for the colder months. It seems that I wouldn't have had any more luck elsewhere in the country – all the patrol groups I contact explain that it's very difficult at this time of year.

They project rescuing nearly 10,000 grown amphibians during migration

A message I get from another volunteer, who has kindly taken the trouble 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 informs me, the team expects to help approximately 10,000 mature amphibians across the road.

Impact and Challenges

How much of a difference can these organizations truly achieve? "The reality that people are performing this regularly on chilly, wet and miserable evenings is quite extraordinary," says an expert. "That's something that very much should be celebrated." However, while rescue teams are able to reduce the drop, they cannot prevent it entirely – not least because vehicles is just one danger.

Additional Threats

The climate crisis has resulted in longer periods of drought, which cause the poor environment for some of the creatures that toads consume, such as worms and slugs, while warmer ponds have caused an rise of blue-green algae, which can be toxic to toads. Milder winters also lead toads to emerge from their hibernation more frequently, disrupting the energy conservation crucial to their existence. Loss of environment – particularly the loss of big water bodies – is another menace.

Experts are "always a bit worried about overemphasizing practical benefits on biodiversity," however "It's important in just having these animals around." But toads do have an significant part in the ecosystem, eating pretty much any invertebrates or small animals they can swallow and in turn sustaining a variety of birds and mammals, such as wildlife. Improving conditions for toads – such as building water habitats, protecting forests and installing amphibian passages – "we'll improve them for a wide range of other species."

Historical Importance

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