It is a Friday evening at half past seven, but rather than going out or watching a film, I've caught a train to a market town in Wiltshire to meet up with local helpers from a toad patrol. These committed people give up their nights to protect the local toad population.

A Worrying Drop in Population

The Bufo bufo is growing more uncommon. A latest study led by an wildlife conservation group showed that the UK toad population have almost halved since 1985. Observing a creature that has been a fixture of the UK landscape in decrease is labeled "worrying" by experts. Toads "don't require very specific conditions" and "should be able to live quite well in the majority of areas in the UK," meaning if even they are not managing to survive, "it kind of suggests that the ecosystem is unbalanced."

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

The Threat from Roads

Though the research didn't cover the causes for the drop, traffic is a major factor. Calculations indicate that 20 tonnes of toads are killed on UK roads annually – that is, hundreds of thousands. Unlike frogs, which might be content to mate "if you left out a bucket of water," toads prefer big bodies of water. Their ability to stay out of water for more time than frogs allows they can journey farther to reach them – sometimes long distances. They usually follow their traditional paths – it's typical for mature amphibians to go back to their natal pond to mate.

Migration Patterns

Fittingly, the initial amphibians begin their quest for a partner around Valentine's day, but some move as far as April, until it gets night and travelling after sunset. During that time, toads start moving from where they have been hibernating "almost simultaneously."

One volunteer, who grew up in the area and has been working to save its toad population since he was a child, notes that "Their sole purpose: to go and mate." If their route crosses a road, they could all get run over, and that breeding season would be lost – preventing a next generation of toads from being born.

Rescue Groups Across the UK

Finding hundreds of toad carcasses on nearby streets "resonates deeply with people," and has resulted in the creation of rescue teams across the UK – 274 groups are officially listed with a national initiative. These teams pick up toads and carry them across roads in buckets, as well as counting the number of toads they find and lobbying for other protection measures, such as blocked roads and underground wildlife tunnels.

Volunteers usually work during the breeding period, when amphibian movements are more regular. However, this means they can miss numbers of toadlets, which, having been eggs and then juveniles, leave their water habitats over an irregular timetable in the end of summer. Because of their small stature – just a couple of cm wide – "they are destroyed by vehicles." And as being hit "essentially crushes them," it's harder to get data on them. At least when mature amphibians are lost, their carcasses can be counted.

Year-Round Work

Unlike most patrols, a specific volunteer group, who are in their eighth year of operating, go out year-round – not every night, but when conditions are damp, or if a member has posted about a amphibian spotting in their group chat. When I request to accompany them on duty, they admit it is "not ideal conditions" – winter dormancy has started and it's been a arid period – but several of the volunteers willingly accept to patrol their area with me and see what we can find. "Should anyone can find any toads tonight, that pair will spot one," says the group coordinator, indicating her teenage child and the experienced member. After for two hours without a glimpse of any amphibians, and now they have scaled a wire barrier to check under some logs.

Family Participation

The family duo joined the group a year and a half ago. The teenager loves all things nature-related and has an ambition to become a conservationist, so his mother started to look for activities they could do jointly to protect native animals. Now she enjoys it as much as he does, the middle-aged entrepreneur tells me – so when the team was looking for a new manager recently, she decided to step up.

The teenager, too, has played an important role in the group. A clip he made, imploring the local council to block a road through a nature reserve during migration season, influenced the outcome the group's way. After a twelve months of lobbying, the authority agreed to an "restricted access" rule between 5pm and 5am from late winter through to April. Most drivers respected and avoided the route.

Other Wildlife and Difficulties

A few vehicles go past when I'm out on patrol and we discover some casualties as a result – no amphibians, but several crushed salamanders. We see one live amphibian as well, and the teenager is especially excited to see a harvestman, which dances in his hands. Yet despite the team's hardest attempts to show me a toad, the local population has obviously settled down for the colder months. It appears that I wouldn't have had any more luck anywhere else in the country – all the patrol groups I contact clarify that it's near-impossible at this time of year.

They project rescuing nearly 10,000 grown amphibians during migration

One email I get from another volunteer, who has kindly taken the trouble to look for toads in a famous site, considered the biggest tracked toad population in the UK, reaches me with the subject line: "No toads." However, in February and March, he tells me, the team expects to help around 10,000 adult toads across the road.

Impact and Challenges

How much of a difference can these groups truly achieve? "The fact that people are performing this regularly on cold, damp and unpleasant evenings is quite extraordinary," says an researcher. "That's something that very much deserves recognition." However, while toad patrols are able to reduce the drop, they can't stop it completely – not least because vehicles is not the only threat.

Additional Threats

The climate crisis has resulted in extended spells of dry weather, which cause the wrong conditions for some of the animals that toads eat, such as worms and slugs, 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 often, disrupting the resource preservation crucial to their life cycle. Loss of environment – particularly the disappearance of large ponds – is an additional threat.

Experts are "often concerned about overemphasizing practical benefits on biodiversity," however "It's important in just their presence." But toads do have an important role in the ecosystem, consuming almost any invertebrates or small animals they can swallow and in turn sustaining a number of birds and mammals, such as hedgehogs and otters. Improving conditions for toads – such as creating more ponds, protecting forests and constructing amphibian passages – "we'll improve them for a whole bunch of additional wildlife."

Historical Significance

An additional motive to work to preserve toads present is their "historical significance," adds an specialist. Legends and tales around toads date back {centuries|hundred
