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

It is Friday evening at half past seven, but instead of heading to the pub or relaxing at home, I've taken a train to a town in the countryside to join local helpers from a toad patrol. These committed people sacrifice their nights to safeguard the local toad population.

A Worrying Decline in Numbers

The Bufo bufo is growing more uncommon. A recent study conducted by an wildlife conservation group showed that the UK toad population have almost halved since the mid-1980s. Seeing a species that has been a stalwart of the British countryside in decline is labeled "concerning" by researchers. Toads "don't need very specific conditions" and "should be able to live successfully in most of habitats in Britain," so if even they are not managing to survive, "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 research didn't examine the reasons for the decline, cars is a major factor. Estimates suggest that 20 tons of toads are crushed on British roads every year – in other words, hundreds of thousands. Unlike frogs, which would probably be happy to mate "if you left out a small container," toads prefer big bodies of water. Their ability to remain away from water for longer than frogs allows they can journey farther to find them – often long distances. They usually stick to their ancestral migration routes – it's common for mature amphibians to return to their natal pond to mate.

Migration Habits

Fittingly, the initial amphibians begin their quest for a mate around Valentine's day, but some move as far as April, until it gets night and moving after sunset. During that period, toads begin migrating from wherever they have been hibernating "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 child, notes that "Their sole purpose: to go and mate." If their path happens to a road, they could all get run over, and that mating period would be lost – stopping a new generation of toads from being born.

Toad Patrols Across the United Kingdom

Seeing many of dead toads on nearby streets "inherently strikes a chord with people," and has led to the formation of rescue teams across the UK – hundreds of organizations are currently registered with a countrywide program. These groups collect toads and carry them over streets in buckets, as well as counting the quantity of toads they find and lobbying for other protection measures, such as road closures and underground wildlife tunnels.

Volunteers tend to operate during the migration season, when toad crossings are frequent. However, this implies they can miss numbers of young toads, which, having been eggs and then juveniles, leave their ponds over an unpredictable schedule in late summer. Because of their size – just one or two centimetres wide – "they can get obliterated by car traffic." And as being hit "essentially crushes them," it's more difficult to collect information on them. At least when mature amphibians are killed, their remains can be counted.

Year-Round Work

In contrast to most patrols, one local team, who are in their eighth season of operating, 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 ask to join them on patrol, they admit it is "not a toady night" – toad hibernation season has started and it's been a dry day – but a few of the helpers willingly accept to patrol their route with me and see what we can find. "If anyone can locate any toads tonight, that pair will find one," says the group coordinator, 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 scaled a wire barrier to check under some wood.

Community Involvement

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 look for things they could do jointly to protect native animals. Now she enjoys it as much as he does, the middle-aged entrepreneur tells me – so when the group was seeking a fresh coordinator lately, she decided to step up.

The youth, too, has played an important role in the organization. A clip he created, imploring the municipal authority to close a street through a nature reserve during migration season, influenced the outcome the team's way. After a twelve months of lobbying, the authority approved an "access-only" rule between 5pm and 5am from February through to April. The majority of motorists duly avoided the road.

Additional Species and Difficulties

A few cars go past when I'm out on patrol and we find some victims as a result – no toads, but three squashed newts. We spot one living newt as well, and the teenager is especially excited to see a harvestman, which moves in his palms. Yet despite the team's hardest attempts to show me a toad, the local population has obviously gone dormant for the colder months. It seems that I wouldn't have had any more luck anywhere else in the country – all the patrol groups I reach out to clarify that it's very difficult at this season.

This team anticipates assisting around ten thousand mature toads over the street

One email I get from another volunteer, who has generously taken the trouble to check for toads in a noted location, thought to be the largest accurately monitored toad group in the UK, arrives in my inbox with the title: "No toads." However, in February and March, he informs me, the team expects to help around 10,000 mature amphibians over the street.

Effectiveness and Limitations

How much of a difference can these groups actually make? "The fact that people are performing this consistently on cold, damp and unpleasant late nights is quite extraordinary," notes an researcher. "This effort that very much deserves recognition." However, while rescue teams are able to slow the decline, they cannot prevent it entirely – partly since traffic is not the only threat.

Other Dangers

The climate crisis has meant extended spells of drought, which create the wrong conditions for some of the animals that toads consume, such as worms and slugs, while warmer ponds have led to an rise of blue-green algae, which can be toxic to toads. Milder winters also lead toads to wake up from their hibernation more often, interfering with the resource preservation vital to their existence. Habitat destruction – particularly the loss of large ponds – is another menace.

Researchers are "often concerned about overemphasizing practical benefits on biodiversity," but "It's important in just their presence." But toads play an important role in the ecosystem, eating pretty much any invertebrates or tiny organisms they can fit in their mouths and in turn feeding a number of predators, such as hedgehogs and otters. Improving conditions for toads – such as building water habitats, protecting forests and constructing amphibian passages – "benefits for a wide range of other species."

Historical Significance

An additional motive to work to preserve toads present is their "important cultural value," adds an expert. Myths and folklore around toads go back {centuries|hundred
