Will Britain's Toads Survive from Roads and Terrible Decline?
It's Friday night at half past seven, but instead of heading to the pub or relaxing at home, I've caught a train to a market town in Wiltshire to meet up with volunteers from a toad patrol. These committed people give up their nights to safeguard the local toad population.
An Alarming Drop in Numbers
The Bufo bufo is becoming increasingly uncommon. A recent study led by an wildlife conservation group showed that the UK toad population have dropped by half since the mid-1980s. Seeing a creature that has been a stalwart of the British countryside in decline is described as "worrying" by researchers. Toads "don't require very particular environments" and "ought to live successfully in most of habitats in Britain," so 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 decline, traffic certainly plays a part. Estimates indicate that 20 tons of toads are crushed on British roads every year – in other words, several hundred thousand. Unlike frogs, which might be happy to mate "with just a bucket of water," toads favor big bodies of water. Their ability to stay out of water for more time than frogs means they can travel further to find them – sometimes hundreds of metres. They usually stick to their ancestral migration routes – it's common for mature amphibians to return to their natal pond to mate.
Migration Habits
Appropriately enough, the initial amphibians begin their quest for a mate around Valentine's day, but some move as far as April, waiting until it gets night and travelling after sunset. During that time, toads begin migrating from where they have been overwintering "almost simultaneously."
A local helper, who grew up in the region and has been trying to protect its amphibians since he was a boy, notes that "They've got just one focus: to go and mate." If their path happens to a road, they could be killed by traffic, and that mating period would never happen – stopping a next generation of toads from being born.
Rescue Groups Across the United Kingdom
Finding hundreds of toad carcasses on nearby streets "inherently strikes a chord with people," and has resulted in the formation of toad patrols throughout the UK – 274 groups are currently registered with a countrywide program. These teams collect toads and transport them over streets in containers, as well as recording the quantity of toads they find and advocating for other safety solutions, such as blocked roads and amphibian passages.
Patrols usually work during the breeding period, when toad crossings are more regular. However, this means they can miss groups of young toads, which, having been spawn and then juveniles, exit their ponds over an unpredictable schedule in the end of summer. Because of their size – just one or two centimetres wide – "they are destroyed by vehicles." And as being run over "basically turns them into mush," it's harder to collect information on them. At least when mature amphibians are lost, their remains can be counted.
Year-Round Work
In contrast to many groups, a specific volunteer group, who are in their eighth year of operating, go out year-round – not every night, but whenever conditions are damp, or if a member has posted about a amphibian spotting in their group chat. When I request to accompany them on patrol, they admit it is "not ideal conditions" – winter dormancy has begun and it's been a arid period – but several of the helpers gamely agree to walk up and down their route with me and see what we can find. "Should anyone can find any toads tonight, that pair will find one," says the group coordinator, pointing to her 14-year-old son and the experienced member. After for two hours without a glimpse of any amphibians, and now they have scaled a wire barrier to inspect beneath some logs.
Community Participation
The mother and son joined the patrol a year and a half ago. The youngster adores all things wildlife and has an ambition to become a conservationist, so his parent started to look for things they could do together to protect native animals. 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 fresh coordinator recently, she volunteered for the role.
The youth, too, has been instrumental in the group. A video he created, imploring the municipal authority to close a road through a nature reserve during breeding time, influenced the outcome the group's way. After a twelve months of lobbying, the authority agreed to an "access-only" rule between 5pm and 5am from February through to April. Most drivers respected and avoided the road.
Additional Species and Challenges
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 living newt as well, and the youngster is especially excited to see a daddy longlegs, which moves in his palms. Yet despite the group's hardest attempts to show me a toad, the native community has obviously settled down for the colder months. It seems that I couldn't have found any better success anywhere else in the country – all the rescue teams I contact explain that it's very difficult at this time of year.
This team anticipates assisting around ten thousand mature toads over the street
One email I get from a different helper, who has kindly made the effort to look for toads in a famous site, considered the biggest tracked toad population in the UK, reaches me with the title: "None found." However, in February and March, he tells me, the group expects to help around ten thousand mature amphibians over the street.
Impact and Limitations
What level of impact can these organizations actually make? "The fact that volunteers are performing this regularly on chilly, wet and miserable evenings is quite extraordinary," says an researcher. "This effort that very much should be celebrated." However, while toad patrols are able to slow the decline, they cannot prevent it entirely – not least because traffic is just one danger.
Additional Threats
The climate crisis has meant extended spells of dry weather, which cause the poor environment for some of the animals that toads consume, such as worms and slugs, while higher water temperatures have led to an rise of toxic plants, which can be harmful to toads. Milder winters also cause toads to wake up from their hibernation more frequently, interfering with the energy conservation vital to their life cycle. Loss of environment – especially the disappearance of big water bodies – is an additional threat.
Researchers 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 do have an important role in the food chain, eating almost any invertebrates or tiny organisms they can swallow and in turn sustaining a variety of birds and mammals, such as hedgehogs and otters. Enhancing conditions for toads – such as building water habitats, conserving woodland and constructing toad tunnels – "we'll improve them for a whole bunch of other species."
Cultural Significance
Another reason to work to preserve toads present is their "historical significance," notes an specialist. Myths and folklore around toads go back {centuries|hundred
