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

It's a Friday evening at 7:30, but rather than going out or relaxing at home, I've taken a train to a town in the countryside to join local helpers from a toad patrol. These dedicated individuals sacrifice their nights to protect the local toad population.

An Alarming Drop in Population

The Bufo bufo is growing more rare. A recent research led by an wildlife conservation group revealed that the British common toad numbers have dropped by half since 1985. Seeing a creature that has been a stalwart of the British countryside in decrease is labeled "concerning" by experts. Toads "don't require very specific conditions" and "ought to live quite well in most of habitats in the UK," meaning if even they are not managing to survive, "it indicates that the ecosystem is unbalanced."

The Threat from Traffic

Though the research didn't examine the causes for the decline, cars is a major factor. Estimates indicate that 20 tons of toads are killed on British roads annually – in other words, hundreds of thousands. In contrast to frogs, which might be content to mate "if you left out a small container," toads favor big bodies of water. Their capacity to stay out of water for more time than frogs allows they can journey farther to reach them – sometimes 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.

Migration Patterns

Appropriately enough, the first toads begin their quest for a partner around Valentine's day, but others travel as late as April, waiting until it gets night and travelling after sunset. During that period, toads begin migrating from wherever they have been hibernating "all pretty much at the same time."

One volunteer, who was raised in the area and has been trying to protect its amphibians since he was a child, notes that "Their sole purpose: to go and have an orgy." If their route crosses a road, they could be killed by traffic, and that breeding season would be lost – stopping a new generation of toads from being produced.

Toad Patrols Across the UK

Finding hundreds of toad carcasses on local roads "resonates deeply with people," and has led to the creation of rescue teams throughout the UK – hundreds of organizations are currently registered with a national initiative. These groups pick up toads and transport them across roads in containers, as well as counting the number of toads they encounter and lobbying for other safety solutions, such as road closures and underground wildlife tunnels.

Patrols tend to operate during the migration season, when amphibian movements are frequent. However, this implies they can miss groups of toadlets, which, having been eggs and then juveniles, exit their ponds 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 run over "essentially crushes them," it's harder to get data on them. At least when mature amphibians are killed, their remains can be tallied.

Annual Efforts

Unlike most patrols, a specific volunteer group, who are in their eighth year of functioning, go out year-round – not every night, but whenever weather are warm and wet, or if someone has posted about a amphibian spotting in their messaging app. When I request to accompany them on duty, they admit it is "not a toady night" – toad hibernation season has begun and it's been a dry day – but a few of the volunteers willingly accept to walk up and down their route with me and see what we can find. "Should anyone can locate any toads tonight, those two will spot one," says the group coordinator, indicating her 14-year-old son and the longtime volunteer. We've been out for 120 minutes without a glimpse of any amphibians, and now they have scaled a wire barrier to check under some wood.

Family Involvement

The family duo became part of the group a year and a half ago. The youngster loves all things nature-related and has an ambition to become a conservationist, so his mother started to search for things they could do jointly to help local wildlife. Now she enjoys it as much as he does, the middle-aged small business owner tells me – so when the team was looking for a new manager recently, she volunteered for the role.

The teenager, too, has played an important role in the organization. A clip he created, imploring the local council to block a road through a protected area during migration season, influenced the outcome the group's way. After a year of lobbying, the authority agreed to an "restricted access" rule between 5pm and 5am from February through to spring. Most drivers duly avoided the road.

Additional Species and Difficulties

A few vehicles go by when I'm out on duty and we find some victims as a consequence – no toads, but three squashed newts. We spot one living newt as well, and the teenager is especially excited to see a harvestman, which dances in his palms. Yet despite the team's hardest attempts to show me a toad, the local population has obviously gone dormant for the winter. It appears that I wouldn't have had any more luck anywhere else in the nation – all the rescue teams I contact clarify that it's very difficult at this time of year.

The group expects to help approximately 10,000 adult toads across the road

One email I get from another volunteer, who has generously made the effort to look for toads in a noted location, considered the largest accurately monitored toad group in the UK, arrives in my inbox with the subject line: "None found." However, in February and March, he tells me, the team expects to help around 10,000 mature amphibians across the road.

Impact and Limitations

How much of a difference can these organizations truly achieve? "The fact that volunteers are doing this regularly on cold, damp and unpleasant evenings is quite extraordinary," says an expert. "This effort that very much should be celebrated." However, while toad patrols are able to reduce the drop, they cannot prevent it entirely – partly since vehicles is just one danger.

Additional Threats

The global warming has meant longer periods of dry weather, which create the poor environment for some of the animals that toads eat, such as worms and slugs, while higher water temperatures have led to an increase of toxic plants, which can be toxic to toads. Milder winters also cause toads to emerge from their dormancy more often, interfering with the energy conservation crucial to their life cycle. Loss of environment – especially the disappearance of big water bodies – is an additional threat.

Experts are "often concerned about putting too much of a utilitarian spin on biodiversity," but "There is a big value in just having these animals around." But toads play an important role in the food chain, consuming almost any small creatures or small animals they can swallow and in turn sustaining a variety of birds and mammals, such as wildlife. Enhancing situations for toads – such as building water habitats, conserving woodland and constructing amphibian passages – "we'll improve them for a whole bunch of additional wildlife."

Historical Significance

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