Can Britain's Toads Be Saved from Traffic and Terrible Decline?
It is Friday evening 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 join local helpers from a amphibian rescue group. These dedicated individuals give up their evenings to safeguard the local toad population.
An Alarming Drop in Population
The Bufo bufo is becoming increasingly rare. A recent research conducted by an amphibian and reptile charity showed that the UK toad population have almost halved since 1985. Seeing a creature that has been a fixture of the UK landscape in decrease is labeled "worrying" by experts. Toads "don't require very particular environments" and "should be able to live successfully in most of areas in the UK," so if even they are struggling to persist, "it indicates that the ecosystem is unbalanced."

The Threat from Traffic
Though the research didn't cover the reasons for the decline, cars certainly plays a part. Calculations indicate that 20 tonnes of toads are crushed on British roads annually – in other words, several hundred thousand. Unlike frogs, which might be content to mate "with just a small container," toads favor large ponds. Their ability to remain away from water for longer than frogs allows they can journey farther to reach them – sometimes hundreds of metres. They tend to stick to their ancestral migration routes – it's common for adult toads to return to their birth pond to mate.
Migration Patterns
Appropriately enough, the first toads start their journey for a mate around February 14th, but others travel as far as April, waiting until it gets dark and moving through the night. During that time, toads start moving from wherever 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, explains that "Their sole purpose: to go and have an orgy." If their path crosses a street, they could be killed by traffic, and that breeding season would be lost – stopping a next generation of toads from being born.
Rescue Groups Throughout the UK
Seeing 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 – hundreds of organizations are officially listed with a countrywide program. These teams collect toads and carry them over streets in buckets, as well as recording the quantity of toads they encounter and advocating for other safety solutions, such as road closures and amphibian passages.
Patrols tend to operate during the breeding period, when amphibian movements are more regular. However, this implies they can miss groups of toadlets, which, having been eggs and then juveniles, exit their ponds over an irregular timetable in late summer. Because of their small stature – just a couple of cm wide – "they can get obliterated by car traffic." And as being run over "basically turns them into mush," it's more difficult to collect information on them. At least when adult toads are lost, their remains can be counted.
Annual Work
In contrast to many groups, one local team, who are in their eighth year of operating, go out throughout the year – not every night, but when conditions 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 gamely agree to walk up and down their area with me and search for any toads. "Should anyone can find any toads tonight, that pair will spot one," says the patrol manager, 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 scaled a wire barrier to inspect beneath some wood.
Community Participation
The family duo joined the patrol a year and a half ago. The youngster loves all things nature-related and has an goal to become a conservationist, so his mother started to look for activities they could do jointly to protect native animals. Now she enjoys it as much as he does, the middle-aged entrepreneur explains – so when the team was looking for a new manager lately, she decided to step up.
The youth, too, has played an important role in the organization. A clip he created, urging the municipal authority to block a street through a nature reserve during migration season, swung the decision the team's way. After a year of lobbying, the authority agreed to an "restricted access" rule between evening and morning from February through to April. The majority of motorists duly avoided the route.
Additional Species and Difficulties
A few cars go past when I'm out on duty and we find some victims as a consequence – no toads, but several crushed salamanders. We spot one live amphibian as well, and the youngster is particularly pleased to see a daddy longlegs, which dances in his palms. Yet in spite of the group's hardest attempts to show me a toad, the native community has obviously gone dormant for the colder months. It seems that I couldn't have found any more luck elsewhere in the country – all the patrol groups I reach out to explain that it's very difficult at this time of year.
This team anticipates assisting around ten thousand mature toads over the street
A message I receive from a different helper, who has generously taken the trouble to check for toads in a noted location, considered the largest accurately monitored toad population in the UK, arrives in my inbox with the subject line: "No toads." However, in late winter, he tells me, the team expects to help approximately ten thousand adult toads across the road.
Effectiveness and Challenges
How much of a difference can these groups truly achieve? "The fact that people are performing this consistently on chilly, wet and miserable late nights is quite extraordinary," notes an expert. "This effort that very much deserves recognition." However, while toad patrols are able to reduce the drop, they can't stop it completely – not least because vehicles is not the only threat.
Other Dangers
The global warming has meant extended spells of drought, which cause the poor environment for some of the animals that toads consume, such as worms and slugs, while higher water temperatures have caused an rise of toxic plants, which can be harmful to toads. Milder winters also cause toads to emerge from their dormancy more often, disrupting the resource preservation vital to their existence. Habitat destruction – particularly the loss of big water bodies – is another menace.
Experts are "always a bit worried about putting too much of a utilitarian spin on wildlife," but "It's important in just their presence." But toads play an important role in the ecosystem, eating almost any invertebrates or tiny organisms they can swallow and in turn sustaining a number of predators, such as wildlife. Improving situations for toads – such as creating more ponds, conserving woodland and constructing amphibian passages – "we'll improve them for a wide range of other species."
Cultural Importance
Another reason to work to preserve toads around is their "historical significance," adds an expert. Myths and folklore around toads go back {centuries|hundred
