Can the UK's Common Toads Survive from Roads and Terrible Decline?

It is Friday night at 7:30, but instead of going out or relaxing at home, I've taken a train to a market town in the countryside to join local helpers from a amphibian rescue group. These dedicated individuals give up their nights to safeguard the native amphibian community.

An Alarming Decline in Numbers

The Bufo bufo is becoming increasingly rare. A recent research led by an amphibian and reptile charity revealed that the UK toad population have dropped by half since the mid-1980s. Seeing a species that has been a fixture of the British countryside in decrease is labeled "concerning" by experts. Toads "don't need very specific conditions" and "ought to live successfully 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."

The Danger from Traffic

Though the study didn't cover the causes for the drop, cars is a major factor. Calculations indicate that 20 tonnes of toads are crushed on British roads every year – in other words, several hundred thousand. In contrast to frogs, which might be content to mate "if you left out a bucket of water," toads favor large ponds. Their ability to remain away from water for more time than frogs allows they can journey farther to reach them – often long distances. They usually stick to their traditional paths – it's typical for adult toads to return to their birth pond to mate.

Breeding Patterns

Fittingly, the initial amphibians begin their quest for a partner around Valentine's day, but some move as late as April, until it gets night and travelling after sunset. During that time, toads start moving from where they have been overwintering "all pretty much at the same time."

A local helper, who grew up in the area and has been trying to protect its amphibians since he was a boy, explains that "Their sole purpose: to go and mate." If their route crosses a road, they could be killed by traffic, and that mating period would never happen – stopping a new generation of toads from being produced.

Rescue Groups Across the UK

Finding many of toad carcasses on nearby streets "inherently strikes a chord with people," and has led to the creation of rescue teams across the UK – hundreds of organizations are currently registered with a national initiative. These groups pick up toads and carry them across roads in containers, as well as recording the quantity of toads they encounter and lobbying for other safety solutions, such as blocked roads and amphibian passages.

Patrols tend to operate during the migration season, when toad crossings are more regular. However, this means they can overlook groups of young toads, which, having been spawn and then tadpoles, exit their water habitats over an irregular timetable in late summer. Because of their small stature – just one or two centimetres wide – "they are destroyed by car traffic." And as being hit "basically turns them into mush," it's more difficult to collect information on them. At least when mature amphibians are lost, their carcasses can be counted.

Annual Work

In contrast to most patrols, one local team, who are in their eighth year of functioning, go out year-round – not nightly, but whenever conditions are damp, or if a member has posted about a toad sighting 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 dry day – but several of the volunteers willingly accept to walk up and down their route with me and see what we can find. "Should anyone can locate any toads tonight, that pair will find one," says the group coordinator, pointing to her teenage child 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 logs.

Community Involvement

The family duo joined the patrol a year and a half ago. The teenager 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 protect native animals. Now she enjoys it as much as he does, the 41-year-old entrepreneur explains – so when the group was looking for a fresh coordinator recently, she decided to step up.

The youth, too, has been instrumental in the group. A video he created, urging the municipal authority to block a street through a protected area during migration season, influenced the outcome the group's way. After a year of campaigning, the council approved an "access-only" restriction between 5pm and 5am from February through to spring. The majority of motorists duly avoided the route.

Other Wildlife and Difficulties

A few vehicles go by when I'm out on patrol and we discover some victims as a result – 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 in spite of the group's best efforts to show me a toad, the local population has obviously settled down for the winter. It seems that I couldn't have found any better success elsewhere in the nation – all the patrol groups I contact clarify that it's very difficult at this season.

A message I receive from a different helper, who has generously taken the trouble to check for toads in a famous site, considered the biggest tracked toad group in the UK, reaches me with the subject line: "None found." However, in February and March, he tells me, the group expects to help approximately ten thousand adult toads over the street.

Impact and Limitations

What level of impact can these groups truly achieve? "The fact that people are doing this consistently on chilly, wet and miserable evenings is quite extraordinary," notes an researcher. "That's something that very much deserves recognition." However, while toad patrols are able to slow the decline, they cannot prevent it entirely – not least because vehicles is just one danger.

Additional Threats

The climate crisis has meant extended spells of drought, which create the poor environment for some of the animals that toads eat, such as worms and slugs, while higher water temperatures have led to an increase of toxic plants, which can be toxic to toads. Milder winters also lead toads to wake up from their hibernation more frequently, interfering with the resource preservation vital to their life cycle. Loss of environment – especially the loss of large ponds – is another menace.

Experts are "often concerned about overemphasizing practical benefits on wildlife," however "There is a big value in just their presence." But toads play an important role in the food chain, consuming almost any invertebrates or tiny organisms they can swallow and in turn feeding a variety of birds and mammals, such as hedgehogs and otters. Improving situations for toads – ie creating more ponds, protecting forests and constructing amphibian passages – "benefits for a whole bunch of other species."

Cultural Importance

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