It's Friday evening at half past seven, but instead of going out or relaxing at home, I've taken a train to a town in the countryside to join volunteers from a amphibian rescue group. These dedicated individuals sacrifice their evenings to safeguard the local toad population.

A Worrying Decline in Population

The Bufo bufo is becoming increasingly uncommon. A recent research led by an amphibian and reptile charity showed that the UK toad population have dropped by half since 1985. Observing a species that has been a fixture of the British countryside in decline is described as "worrying" by experts. Toads "don't require very particular environments" and "ought to live successfully in the majority of areas in the UK," meaning if even they are struggling to persist, "it indicates that the ecosystem is unbalanced."

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

The Danger from Roads

Though the study didn't examine the causes for the drop, traffic certainly plays a part. Calculations suggest that 20 tonnes of toads are killed on UK roads every year – 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 favor big bodies of water. Their capacity to remain away from water for more time than frogs means they can travel further to reach them – sometimes long distances. They usually stick to their ancestral migration routes – it's typical for mature amphibians to return to their birth pond to mate.

Breeding Patterns

Appropriately enough, the initial amphibians begin their quest for a mate around Valentine's day, but others travel as late as spring, until it gets dark and travelling through the night. During that period, toads start moving from wherever they have been hibernating "almost simultaneously."

A local helper, who grew up in the area and has been trying to protect its amphibians since he was a boy, notes that "They've got just one focus: to go and have an orgy." If their path happens to a street, they could all get run over, and that mating period would never happen – preventing a next generation of toads from being born.

Toad Patrols Throughout the UK

Finding many of toad carcasses on nearby streets "resonates deeply with people," and has resulted in the formation of rescue teams across the UK – 274 groups are officially listed with a countrywide program. 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.

Patrols usually work during the breeding period, when amphibian movements are frequent. However, this means they can miss numbers of toadlets, which, having existed as eggs and then juveniles, exit their water habitats over an unpredictable schedule in late summer. Because of their small stature – just one or two centimetres wide – "they are destroyed by car traffic." And as being hit "essentially crushes them," 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 many groups, one local team, who are in their eighth season of operating, go out throughout the year – not every night, but when conditions are damp, or if a member has reported about a toad sighting in their messaging app. When I request to accompany them on duty, they concede it is "not a toady night" – winter dormancy has begun and it's been a dry day – but a few of the volunteers gamely agree to walk up and down their route with me and see what we can find. "If anyone can locate any toads tonight, those two will find one," says the patrol manager, pointing to her 14-year-old son and the experienced member. We've been out for two hours without a single toad sighting, and now they have climbed over a barbed wire fence to inspect beneath some logs.

Community Participation

The mother and son joined the group a year and a half ago. The teenager loves all things nature-related and has an ambition to become a environmentalist, so his mother started to look for things they could do jointly to help local wildlife. Now she enjoys it as much as he does, the 41-year-old entrepreneur explains – so when the team was seeking a fresh coordinator recently, she volunteered for the role.

The youth, too, has been instrumental in the organization. A video he created, imploring the local council to block a street through a protected area during migration season, influenced the outcome the team's way. After a twelve months of campaigning, the council approved an "access-only" rule between evening and morning from February through to April. Most drivers duly avoided the route.

Other Wildlife and Challenges

A few cars go by when I'm out on patrol and we find some casualties as a consequence – no toads, but several crushed salamanders. We spot one live amphibian as well, and the teenager is especially excited to see a daddy longlegs, which moves in his palms. Yet despite the team's best efforts to show me a toad, the local population has obviously gone dormant for the colder months. It appears that I wouldn't have had any better success anywhere else in the nation – all the rescue teams I reach out to clarify that it's very difficult at this season.

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 look for toads in a noted location, thought to be the biggest tracked toad group in the UK, arrives in my inbox with the title: "No toads." However, in late winter, he tells me, the group expects to help approximately 10,000 adult toads across the road.

Impact and Limitations

How much of a difference can these groups truly achieve? "The fact that volunteers are doing this consistently on chilly, wet and miserable late nights is quite extraordinary," says 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 climate crisis has resulted in longer periods of dry weather, which cause the wrong conditions for some of the creatures that toads eat, such as worms and slugs, while warmer ponds have led to an increase of blue-green algae, which can be harmful to toads. Milder winters also cause toads to emerge from their hibernation more often, disrupting the resource preservation crucial to their existence. Habitat destruction – particularly the disappearance of big water bodies – is another menace.

Researchers are "always a bit worried about putting too much of a utilitarian spin on biodiversity," however "There is a big value in just having these animals around." But toads play an significant part in the food chain, consuming almost any invertebrates or tiny organisms they can swallow and in turn feeding a number of birds and mammals, such as hedgehogs and otters. Enhancing situations for toads – such as creating more ponds, conserving woodland and constructing toad tunnels – "benefits for a whole bunch of additional wildlife."

Historical Significance

An additional motive to try to keep toads around is their "historical significance," notes an expert. Legends and tales around toads date back {centuries|hundred
