Can Britain's Common Toads Be Saved from Roads and Terrible Decline?
It's Friday night at 7:30, but rather than heading to the pub or watching a film, I've caught a train to a market town in the countryside to meet up with local helpers from a amphibian rescue group. These dedicated individuals sacrifice their evenings to safeguard the native amphibian community.
A Worrying Decline in Population
The Bufo bufo is becoming increasingly rare. A recent study conducted by an wildlife conservation group revealed that the UK toad population have almost halved since the mid-1980s. Seeing a creature that has been a fixture of the UK landscape in decline is labeled "concerning" by researchers. Toads "don't require very particular environments" and "ought to live successfully in the majority of habitats in the UK," meaning if even they are struggling to persist, "it kind of suggests that the ecosystem is unbalanced."

The Danger from Roads
Though the study didn't cover the reasons for the drop, cars certainly plays a part. Calculations indicate that 20 tons of toads are killed on British roads annually – in other words, hundreds of thousands. Unlike frogs, which would probably be content to mate "if you left out a bucket of water," toads prefer big bodies of water. Their capacity to stay out of water for longer than frogs allows they can journey farther to reach them – sometimes hundreds of metres. They usually stick to their ancestral migration routes – it's typical for mature amphibians to go back to their natal pond to mate.
Migration Patterns
Fittingly, the first toads begin their quest for a partner around February 14th, but some move as far as spring, until it gets dark and moving through the night. During that time, toads begin migrating from where they have been hibernating "almost simultaneously."
A local helper, who was raised in the area and has been working to save its toad population since he was a child, explains that "They've got just one focus: to go and mate." If their route crosses a street, they could be killed by traffic, and that mating period would never happen – preventing a next generation of toads from being produced.
Toad Patrols Across the UK
Finding many of dead toads on nearby streets "inherently strikes a chord with people," and has led to the creation of toad patrols across the UK – 274 groups are officially listed with a countrywide program. These teams collect toads and transport them over streets in buckets, as well as recording the number of toads they find and advocating for other safety solutions, such as blocked roads and underground wildlife tunnels.
Patrols tend to operate during the migration season, when amphibian movements are more regular. However, this implies they can overlook groups of toadlets, which, having been spawn and then juveniles, 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 run over "basically turns them into mush," it's harder to collect information on them. At least when adult toads are killed, their remains can be counted.
Annual Work
Unlike most patrols, one local team, who are in their eighth season of operating, go out year-round – not nightly, but whenever weather are warm and wet, or if a member has reported about a amphibian spotting in their messaging app. When I ask to join them on patrol, they admit it is "not a toady night" – winter dormancy has started and it's been a dry day – but a few of the volunteers willingly accept to patrol their area with me and search for any toads. "If anyone can locate any toads tonight, those two will find one," says the group coordinator, pointing to her 14-year-old son and the longtime volunteer. We've been out for 120 minutes without a single toad sighting, and now they have climbed over a wire barrier to check under some wood.
Family Participation
The mother and son became part of the patrol a year and a half ago. The teenager adores all things wildlife and has an ambition to become a conservationist, so his mother started to search for activities they could do together to help native animals. Now she enjoys it as much as he does, the middle-aged entrepreneur explains – so when the team was seeking a new manager lately, she volunteered for the role.
The youth, too, has been instrumental in the group. A clip he created, urging the local council to block a street through a nature reserve during breeding time, influenced the outcome the group's way. After a twelve months of lobbying, the authority approved an "restricted access" rule between 5pm and 5am from late winter through to April. The majority of motorists respected and avoided the route.
Other Wildlife and Challenges
Several cars go by when I'm out on duty and we discover some casualties as a consequence – no amphibians, but three squashed newts. We see one living newt as well, and the teenager is particularly pleased to see a daddy longlegs, which moves in his palms. Yet in spite of the team's best efforts to let me see a toad, the local population has clearly settled down for the colder months. It appears that I wouldn't have had any more luck anywhere else in the country – all the patrol groups I reach out to explain that it's near-impossible at this time of year.
They project rescuing nearly 10,000 grown amphibians during migration
One email I receive from another volunteer, who has generously made the effort to look for toads in a noted location, considered the biggest tracked toad group in the UK, reaches me with the subject line: "None found." However, in late winter, he tells me, the group plans to assist around 10,000 adult toads across the road.
Effectiveness and Challenges
What level of impact can these groups actually make? "The reality that people are performing this consistently on chilly, wet and miserable evenings is remarkable," says an researcher. "That's something that very much should be celebrated." 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 global warming has meant longer periods of drought, which create the poor environment 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 dormancy more frequently, disrupting the resource preservation vital to their life cycle. Loss of environment – particularly the disappearance of big water bodies – is another menace.
Researchers are "often concerned about putting too much of a utilitarian spin on biodiversity," however "It's important in just their presence." But toads do have an significant part in the ecosystem, consuming almost any small creatures or small animals they can fit in their mouths and in turn feeding a variety of birds and mammals, such as wildlife. Enhancing conditions for toads – ie building water habitats, conserving woodland and installing toad tunnels – "benefits for a whole bunch of other species."
Cultural Importance
Another reason to work to preserve toads present is their "historical significance," notes an expert. Myths and folklore around toads date back {centuries|hundred
