Can Britain's Common Toads Be Saved from Roads and Population Collapse?

It is Friday night at 7:30, but rather than heading to the pub or watching a film, I've taken a train to a market town in the countryside to join local helpers from a amphibian rescue group. These committed people give up their nights to protect the local toad population.

A Worrying Decline in Population

The Bufo bufo is growing more rare. A recent study conducted by an amphibian and reptile charity revealed that the British common toad numbers have dropped by half since the mid-1980s. Observing a creature that has been a stalwart of the British countryside in decline is labeled "worrying" by researchers. Toads "don't need very specific conditions" and "ought to live successfully in the majority of habitats in the UK," meaning if even they are not managing to survive, "it indicates that things are not as they should be."

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

The Threat from Roads

Though the research didn't examine the causes for the drop, cars is a major factor. Estimates indicate that 20 tons of toads are killed on British roads annually – in other words, several hundred thousand. Unlike frogs, which might be content to mate "with just a small container," toads prefer big bodies of water. Their capacity to stay out of water for longer than frogs allows they can travel further to reach them – often hundreds of metres. They tend to stick to their traditional paths – it's common for mature amphibians to go back to their natal pond to mate.

Breeding Habits

Fittingly, the initial amphibians begin their quest for a partner around Valentine's day, but some move as late as April, until it gets dark and moving after sunset. During that period, toads begin migrating from where they have been overwintering "almost simultaneously."

One volunteer, who was raised in the area and has been trying to protect its toad population since he was a boy, notes that "Their sole purpose: to go and mate." If their path happens to a street, they could be killed by traffic, and that breeding season would never happen – stopping a new generation of toads from being produced.

Toad Patrols Across the UK

Seeing hundreds of toad carcasses on nearby streets "resonates deeply with people," and has resulted in the creation of toad patrols throughout the UK – hundreds of organizations are currently registered with a national initiative. These teams collect toads and carry them across roads in containers, as well as recording the number of toads they encounter and lobbying for other protection measures, such as blocked roads and amphibian passages.

Volunteers tend to operate during the migration season, when toad crossings are frequent. However, this implies they can miss groups of young toads, which, having been spawn and then juveniles, exit their water habitats over an irregular timetable in the end of summer. Because of their size – just a couple of cm wide – "they can get obliterated by car traffic." And as being run over "essentially crushes them," it's harder to collect information on them. At least when mature amphibians are lost, their remains can be counted.

Year-Round Work

Unlike most patrols, a specific volunteer group, who are in their eighth year of functioning, go out throughout the year – not nightly, but when conditions are damp, or if a member has posted about a amphibian spotting in their messaging app. When I ask to join them on patrol, they concede it is "not a toady night" – winter dormancy has started and it's been a dry day – but a few of the helpers gamely agree to patrol their route with me and search for any toads. "Should anyone can locate any toads tonight, those two will spot 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 glimpse of any amphibians, and now they have climbed over a wire barrier to inspect beneath some logs.

Community Participation

The family duo became part of the patrol a year and a half ago. The youngster adores all things wildlife and has an goal to become a conservationist, so his parent started to search for activities they could do jointly to help native animals. Now she enjoys it as much as he does, the 41-year-old small business owner explains – so when the group was looking for a fresh coordinator lately, she volunteered for the role.

The teenager, too, has been instrumental in the organization. A video he created, imploring the local council to block a street through a nature reserve during breeding time, influenced the outcome the team's way. After a twelve months of lobbying, the council agreed to an "access-only" rule between 5pm and 5am from late winter through to April. The majority of motorists respected and avoided the route.

Other Wildlife and Difficulties

Several vehicles go by when I'm out on duty and we discover some casualties as a result – no toads, but three squashed newts. We spot one live amphibian as well, and the youngster 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 local population has obviously settled down for the winter. It seems that I wouldn't have had any better success elsewhere in the nation – all the rescue teams I contact 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 receive from a different helper, who has generously taken the trouble to look for toads in a famous site, thought to be the largest accurately monitored toad group in the UK, arrives in my inbox 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.

Impact and Challenges

How much of a difference can these organizations actually make? "The fact that people are performing this regularly on chilly, wet and miserable late nights is quite extraordinary," notes an researcher. "This effort that very much should be celebrated." However, while rescue teams are able to slow the decline, they cannot prevent it entirely – partly since vehicles is just one danger.

Other Dangers

The climate crisis has meant extended spells of drought, which cause the wrong conditions for some of the creatures that toads consume, such as worms and slugs, while warmer ponds have caused an rise of toxic plants, which can be toxic to toads. Warmer cold seasons also cause toads to wake up from their hibernation more often, disrupting the resource preservation vital to their existence. Loss of environment – particularly the disappearance of big water bodies – is another menace.

Experts are "always a bit worried about putting too much of a utilitarian spin on biodiversity," however "There is a big value in just their presence." But toads play an significant part in the ecosystem, eating pretty much any invertebrates or small animals they can fit in their mouths and in turn feeding a number of predators, such as hedgehogs and otters. Improving conditions for toads – ie building water habitats, conserving woodland and constructing toad tunnels – "benefits for a whole bunch of additional wildlife."

Historical Importance

An additional motive to try to keep toads present is their "important cultural value," notes an specialist. Legends and tales around toads date back {centuries|hundred
