Will the UK's Common Toads Survive from Traffic and Population Collapse?

It is a Friday night at half past seven, but instead of heading to the pub or watching a film, I've caught a train to a town in the countryside to meet up with volunteers from a toad patrol. These committed people sacrifice their evenings to safeguard the local toad population.

An Alarming Drop in Population

The common toad is becoming increasingly rare. A recent research conducted by an wildlife conservation group revealed that the UK toad population have almost halved since the mid-1980s. Seeing a species that has been a fixture of the UK landscape in decline is labeled "concerning" by researchers. Toads "don't need very specific conditions" and "ought to live quite well in most of habitats in Britain," meaning if even they are struggling to persist, "it kind of suggests that the ecosystem is unbalanced."

The Danger from Roads

Though the research didn't examine the reasons for the drop, traffic certainly plays a part. Estimates suggest that 20 tons of toads are killed on British roads every year – in other words, several hundred thousand. Unlike frogs, which might be happy to mate "with just a small container," toads prefer big bodies of water. Their capacity to stay out of water for longer than frogs means they can travel further 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.

Migration Habits

Fittingly, 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 moving through the night. During that time, toads begin migrating from wherever they have been hibernating "almost simultaneously."

One volunteer, who grew up in the region and has been working to save its toad population since he was a child, explains that "Their sole purpose: to go and have an orgy." If their route crosses a road, they could all get run over, and that mating period would be lost – stopping a new generation of toads from being born.

Rescue Groups Throughout the United Kingdom

Seeing hundreds of toad carcasses on local roads "resonates deeply with people," and has resulted in the formation of rescue teams across the UK – hundreds of organizations are currently registered with a countrywide program. These groups pick up toads and transport them across roads in containers, as well as counting the quantity of toads they find and advocating for other safety solutions, such as blocked roads and amphibian passages.

Patrols tend to operate during the migration season, when amphibian movements are more regular. However, this implies they can overlook groups of young toads, which, having been eggs and then tadpoles, leave their ponds over an unpredictable schedule in the end of summer. Because of their size – just a couple of cm wide – "they can get obliterated by vehicles." And as being hit "basically turns them into mush," it's harder to get data on them. At least when adult toads are killed, their carcasses can be counted.

Year-Round Work

In contrast to most patrols, one local team, who are in their eighth year 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 group chat. When I request to accompany them on patrol, they concede it is "not ideal conditions" – toad hibernation season has started and it's been a arid period – but a few of the volunteers willingly accept to patrol their route with me and search for any toads. "Should anyone can locate 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 two hours without a glimpse of any amphibians, and now they have scaled a wire barrier to inspect beneath some logs.

Family Participation

The mother and son became part of the patrol a while back. The youngster adores all things nature-related and has an ambition to become a conservationist, so his mother started to look for activities they could do together to help native animals. Now she loves it as much as he does, the 41-year-old entrepreneur tells me – so when the team was seeking a new manager lately, she decided to step up.

The teenager, too, has been instrumental in the organization. A clip he made, imploring the local council to close a road through a protected area during migration season, swung the decision the group's way. After a twelve months of lobbying, the council 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 vehicles go past when I'm out on patrol and we find some casualties as a result – no amphibians, but three squashed newts. We spot one live amphibian as well, and the youngster is especially excited to see a daddy longlegs, which moves in his hands. Yet despite the team's hardest attempts to show me a toad, the native community has obviously settled down for the winter. It seems that I couldn't have found any more luck elsewhere in the nation – all the rescue teams I reach out to clarify that it's very difficult at this time of year.

One email I receive from a different helper, who has kindly taken the trouble to look for toads in a famous site, considered the biggest tracked toad population in the UK, arrives in my inbox with the subject line: "No toads." However, in late winter, he tells me, the group plans to assist approximately ten thousand mature amphibians over the street.

Impact and Challenges

What level of impact can these groups actually make? "The reality that volunteers are performing this regularly on cold, damp and unpleasant evenings is quite extraordinary," notes an expert. "That's something that very much should be celebrated." However, while rescue teams are able to slow the decline, they can't stop it completely – not least because vehicles is just one danger.

Other Dangers

The global warming has meant longer periods of drought, which create the wrong conditions for some of the creatures that toads consume, such as worms and slugs, while warmer ponds have led to an rise of toxic plants, which can be harmful to toads. Warmer cold seasons also lead toads to emerge from their hibernation more often, disrupting the energy conservation crucial to their existence. Habitat destruction – especially the disappearance of large ponds – is another menace.

Researchers 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 ecosystem, consuming pretty much any small creatures or small animals they can fit in their mouths and in turn feeding a number of birds and mammals, such as wildlife. Improving conditions for toads – such as building water habitats, protecting forests and installing amphibian passages – "we'll improve them for a whole bunch of additional wildlife."

Cultural Significance

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