It's a Friday night at half past seven, but instead of going out or relaxing at home, I've taken a train to a market town in the countryside to join volunteers from a amphibian rescue group. These committed people give up their evenings to protect the local toad population.

A Worrying Decline in Population

The Bufo bufo is becoming increasingly uncommon. A latest study led by an amphibian and reptile charity revealed that the UK toad population have dropped by half since the mid-1980s. Seeing a creature that has been a stalwart of the UK landscape in decrease is described as "concerning" by experts. Toads "don't require very specific conditions" and "ought to live successfully in the majority of habitats in Britain," meaning if even they are struggling to persist, "it indicates that the ecosystem is unbalanced."

The Danger from Traffic

Though the study didn't examine the causes for the drop, cars certainly plays a part. Calculations indicate that 20 tonnes of toads are killed on UK roads annually – in other words, several hundred thousand. In contrast to frogs, which might be content to mate "with just a bucket of water," toads favor large ponds. Their capacity to stay out of water for longer than frogs means they can journey farther to find them – often long distances. They tend to stick to their ancestral migration routes – it's typical for mature amphibians to return to their natal pond to mate.

Migration Patterns

Appropriately enough, the first toads start their journey for a mate around Valentine's day, but some move as far as April, until it gets night and travelling through the night. During that time, toads begin migrating from wherever they have been overwintering "almost simultaneously."

A local helper, who grew up in the area and has been working to save its amphibians since he was a child, explains that "Their sole purpose: to go and mate." If their route happens to a road, they could all get run over, and that mating period would never happen – preventing a next generation of toads from being born.

Rescue Groups Across the UK

Finding many of toad carcasses on nearby streets "resonates deeply with people," and has led to the formation of rescue teams across the UK – hundreds of organizations are currently registered with a national initiative. These teams pick up toads and carry them over streets in buckets, as well as recording the number of toads they encounter and lobbying for other safety solutions, such as blocked roads and underground wildlife tunnels.

Volunteers tend to operate during the migration season, when toad crossings are frequent. However, this means they can miss groups of young toads, which, having been spawn and then juveniles, leave their water habitats over an irregular timetable in late summer. Because of their size – just one or two centimetres wide – "they are destroyed by car traffic." And as being run over "basically turns them into mush," it's more difficult to get data on them. At least when mature amphibians are killed, their carcasses can be tallied.

Year-Round Efforts

In contrast to most patrols, one local team, who are in their eighth year of operating, go out throughout the year – not nightly, but whenever weather are damp, or if a member has posted about a amphibian spotting in their messaging app. When I ask to join them on duty, they concede it is "not a toady night" – winter dormancy has started and it's been a arid period – but a few of the volunteers willingly accept to walk up and down their area with me and see what we can find. "If anyone can find any toads tonight, those two will find one," says the patrol manager, 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 check under some wood.

Community Involvement

The family duo joined the patrol a while back. The teenager loves all things wildlife and has an ambition to become a environmentalist, so his parent started to look for activities they could do together to protect local wildlife. Now she enjoys it as much as he does, the 41-year-old small business owner tells me – so when the group was seeking a new manager lately, she decided to step up.

The teenager, too, has played an important role in the group. A clip he made, urging the local council to close a street through a nature reserve during migration season, swung the decision the group's way. After a twelve months of lobbying, the council agreed to an "restricted access" rule between evening and morning from February through to April. The majority of motorists duly avoided the route.

Additional Species and Challenges

A few cars go by when I'm out on duty and we discover some victims as a consequence – no toads, but three squashed newts. We see one live amphibian as well, and the teenager is especially excited to see a harvestman, which moves in his palms. Yet in spite of the team's hardest attempts to let me see a toad, the native community has clearly settled down for the colder months. It seems that I couldn't have found any more luck elsewhere in the country – all the rescue teams I reach out to explain that it's very difficult at this time of year.

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

One email I receive from another volunteer, who has kindly taken the trouble to check for toads in a noted location, considered the largest accurately monitored toad population in the UK, arrives in my inbox with the title: "None found." However, in late winter, he informs me, the group plans to assist around ten thousand adult toads across the road.

Impact and Limitations

What level of impact can these groups truly achieve? "The reality that volunteers are doing this regularly on cold, damp and unpleasant late nights is remarkable," notes an expert. "This effort that very much should be celebrated." However, while toad patrols are able to reduce the drop, they cannot prevent it entirely – not least because traffic is just one danger.

Other Dangers

The climate crisis has resulted in extended spells of drought, which create the poor environment for some of the creatures that toads eat, such as worms and slugs, while higher water temperatures have caused an increase of toxic plants, 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 life cycle. Habitat destruction – especially the disappearance of large ponds – is an additional threat.

Researchers are "always a bit worried about putting too much of a utilitarian spin on biodiversity," but "There is a big value in just their presence." But toads do have an important role in the food chain, eating almost any invertebrates or tiny organisms they can swallow and in turn sustaining a number of birds and mammals, such as wildlife. Improving conditions for toads – ie creating more ponds, protecting forests and installing amphibian passages – "we'll improve them for a whole bunch of other species."

Historical Significance

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