Will the UK's Common Toads Be Saved from Traffic and Terrible Decline?
It is Friday evening at 7:30, but rather than heading to the pub or relaxing at home, I've caught a train to a market town in Wiltshire to meet up with local helpers from a amphibian rescue group. These committed people give up their evenings to protect the native amphibian community.
A Worrying Drop in Numbers
The common toad is growing more uncommon. A latest study led by an wildlife conservation group revealed that the British common toad numbers have almost halved since the mid-1980s. Observing a creature that has been a stalwart of the British countryside in decline is labeled "concerning" by researchers. Toads "don't require very specific conditions" and "ought to live quite well in the majority of areas in Britain," meaning if even they are not managing to survive, "it indicates that things are not as they should be."

The Threat from Roads
Though the study didn't examine the reasons for the decline, cars is a major factor. Calculations suggest that 20 tons of toads are killed on British roads annually – that is, hundreds of thousands. Unlike frogs, which would probably be content to mate "if you left out a small container," toads favor large ponds. Their capacity to remain away from water for more time than frogs allows they can journey farther to find them – often long distances. They tend to stick to their traditional paths – it's typical for mature amphibians to go back to their birth pond to mate.
Breeding Habits
Appropriately enough, the first toads begin their quest for a mate around Valentine's day, but some move as far as April, waiting until it gets dark and moving through the night. During that time, toads begin migrating from where they have been hibernating "all pretty much at the same time."
A local helper, who was raised in the region and has been working to save its toad population since he was a boy, explains that "They've got just one focus: to go and have an orgy." If their path crosses a road, they could all get run over, and that mating period would be lost – preventing a next generation of toads from being produced.
Toad Patrols Throughout the UK
Finding many of dead toads on nearby streets "inherently strikes a chord with people," and has resulted in the creation of toad patrols across the UK – 274 groups are officially listed with a national initiative. These groups pick up toads and transport them across roads in containers, as well as counting the quantity of toads they find and lobbying for other safety solutions, such as blocked roads and underground wildlife tunnels.
Volunteers usually work during the breeding period, when amphibian movements are more regular. However, this implies they can overlook groups of toadlets, which, having existed as spawn and then tadpoles, exit their water habitats over an irregular timetable in the end of summer. Because of their size – just a couple of cm wide – "they are destroyed by vehicles." And as being hit "essentially crushes them," it's harder to collect information on them. At least when mature amphibians are killed, their remains can be tallied.
Annual Work
Unlike many groups, one local team, who are in their eighth year of functioning, go out year-round – not every night, but whenever weather 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" – toad hibernation season has started and it's been a arid period – but several of the helpers gamely agree to patrol their route with me and see what we can find. "If anyone can locate any toads tonight, those two will find one," says the group coordinator, indicating her teenage child and the experienced member. We've been out for 120 minutes without a glimpse of any amphibians, and now they have scaled a barbed wire fence to inspect beneath some logs.
Family Participation
The mother and son joined the patrol a year and a half ago. The teenager adores all things nature-related and has an goal 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 entrepreneur explains – so when the group was looking for a fresh coordinator recently, she volunteered for the role.
The youth, too, has played an important role in the organization. A video he created, imploring the municipal authority to block a street through a protected area during migration season, swung the decision the team's way. After a year of lobbying, the council approved an "access-only" restriction between 5pm and 5am from February through to April. The majority of motorists respected and avoided the road.
Additional Species and Challenges
A few cars go by when I'm out on patrol and we discover some victims as a consequence – no amphibians, but three squashed newts. We spot one live amphibian as well, and the teenager is especially excited to see a daddy longlegs, which moves in his hands. Yet in spite of the group's best efforts to show me a toad, the local population has clearly settled down for the colder months. It seems that I couldn't have found any better success anywhere else in the nation – all the patrol groups I reach out to clarify that it's near-impossible at this time of year.
This team anticipates assisting around ten thousand mature toads over the street
One email I receive from another volunteer, who has kindly made the effort to look for toads in a noted location, thought to be the largest accurately monitored toad group in the UK, reaches me with the subject line: "No toads." However, in February and March, he tells me, the group plans to assist approximately ten thousand adult toads over the street.
Effectiveness and Challenges
How much of a difference can these organizations truly achieve? "The fact that people are performing this consistently on chilly, wet and miserable late nights is remarkable," notes an researcher. "This effort that very much deserves recognition." However, while toad patrols are able to slow the decline, they cannot prevent it entirely – partly since vehicles is not the only threat.
Additional Threats
The global warming has resulted in longer periods of drought, which create the wrong conditions for some of the creatures that toads consume, such as worms and slugs, while higher water temperatures have led to an rise of toxic plants, which can be toxic to toads. Milder winters also cause toads to emerge from their hibernation more frequently, disrupting the energy conservation vital to their existence. Habitat destruction – particularly the loss of big water bodies – is an additional threat.
Experts are "always a bit worried about putting too much of a utilitarian spin on biodiversity," but "It's important in just their presence." But toads play an significant part in the food chain, consuming almost any small creatures or tiny organisms they can swallow and in turn feeding a variety of predators, such as wildlife. Enhancing conditions for toads – ie creating more ponds, conserving woodland and installing toad tunnels – "benefits for a whole bunch of additional wildlife."
Historical Significance
An additional motive to try to keep toads around is their "important cultural value," notes an expert. Myths and folklore around toads go back {centuries|hundred
