It is Friday night 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 committed people sacrifice their evenings to protect the native amphibian community.

An Alarming Drop in Numbers

The Bufo bufo is growing more uncommon. A latest study led by an wildlife conservation group revealed that the British common toad numbers have almost halved since 1985. Seeing a species that has been a stalwart of the UK landscape in decrease is labeled "concerning" by researchers. Toads "don't require very particular environments" and "should be able to live quite well in the majority of habitats in Britain," meaning if even they are not managing to survive, "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 cover the reasons for the decline, cars is a major factor. Estimates indicate that 20 tons of toads are killed on British roads every year – in other words, several hundred thousand. In contrast to frogs, which would probably be happy 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 means they can travel further to reach them – often long distances. They tend to stick to their traditional paths – it's common for adult toads to return to their natal pond to mate.

Breeding Patterns

Fittingly, the initial amphibians begin their quest for a mate around February 14th, but some move as late as spring, until it gets dark and travelling through the night. During that period, toads start moving from where 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 toad population since he was a child, 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 breeding season would be lost – preventing a new generation of toads from being born.

Toad Patrols Across the United Kingdom

Finding many of toad carcasses on local roads "inherently strikes a chord with people," and has resulted in the formation of rescue teams across the UK – hundreds of organizations are currently registered with a national initiative. These teams collect toads and transport them over streets in buckets, as well as counting the quantity of toads they find and lobbying for other safety solutions, such as blocked roads and underground wildlife tunnels.

Patrols usually work during the migration season, when toad crossings are frequent. However, this means they can miss groups of toadlets, which, having existed as spawn and then juveniles, exit their ponds over an irregular timetable in the end of summer. Because of their size – just a couple of cm wide – "they are destroyed by car traffic." And as being hit "basically turns them into mush," it's harder to get data on them. At least when adult toads are lost, their carcasses can be tallied.

Annual Efforts

In contrast to many groups, a specific volunteer group, 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 toad sighting in their group chat. When I request to accompany them on duty, 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 walk up and down their route with me and see what we can find. "If anyone can find any toads tonight, those two will spot one," says the group coordinator, pointing to her 14-year-old son and the longtime volunteer. We've been out for 120 minutes without a single toad sighting, and now they have scaled a wire barrier to inspect beneath some wood.

Community Involvement

The mother and son became part of the group a year and a half ago. The youngster adores all things nature-related and has an goal to become a environmentalist, so his mother started to look for activities they could do jointly to help native animals. Now she loves it as much as he does, the middle-aged small business owner explains – so when the team was looking for a fresh coordinator recently, she decided to step up.

The youth, too, has been instrumental in the organization. A video he made, imploring the municipal authority to block a street through a nature reserve during breeding time, swung the decision the team's way. After a year of campaigning, the council agreed to an "access-only" rule between evening and morning from late winter through to spring. Most drivers respected and avoided the road.

Additional Species and Challenges

Several vehicles go by when I'm out on patrol and we discover some casualties as a consequence – no amphibians, but three squashed newts. We spot one living newt as well, and the youngster is especially excited to see a harvestman, which dances in his palms. Yet despite the team's hardest attempts to let me see a toad, the local population has obviously settled down for the colder months. It appears that I wouldn't have had any better success anywhere else in the country – all the rescue teams I reach out to explain that it's near-impossible 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 kindly made the effort to check for toads in a famous site, thought to be the biggest tracked toad group in the UK, reaches me with the title: "None found." However, in late winter, he tells me, the team expects to help around ten thousand adult toads over the street.

Effectiveness and Challenges

What level of impact can these organizations actually make? "The fact that people are doing this consistently on cold, damp and unpleasant evenings is remarkable," says an expert. "This effort that very much should be celebrated." However, while toad patrols are able to reduce the drop, they can't stop it completely – partly since traffic is just one danger.

Additional Threats

The climate crisis has resulted in longer periods of dry weather, which cause the poor environment for some of the creatures that toads eat, such as invertebrates, while warmer ponds have caused an increase of blue-green algae, which can be toxic to toads. Warmer cold seasons also cause toads to emerge from their dormancy more often, disrupting the energy conservation crucial to their life cycle. Habitat destruction – especially the loss of big water bodies – is an additional threat.

Researchers are "always a bit worried about overemphasizing practical benefits on biodiversity," but "There is a big value in just their presence." But toads do have an important role in the ecosystem, consuming almost any small creatures or tiny organisms they can swallow and in turn feeding a number of birds and mammals, such as wildlife. Improving situations for toads – ie creating more ponds, protecting forests and installing toad tunnels – "we'll improve them for a whole bunch of additional wildlife."

Historical Importance

Another reason to work to preserve toads around is their "historical significance," notes an specialist. Legends and tales around toads date back {centuries|hundred
