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

It is Friday evening at half past seven, but instead of heading to the pub or watching a film, I've taken a train to a town in Wiltshire to meet up with volunteers from a amphibian rescue group. These committed people sacrifice their evenings to safeguard the native amphibian community.

A Worrying Decline in Population

The common toad is growing more uncommon. A recent study conducted by an wildlife conservation group showed that the British common toad numbers have dropped by half since the mid-1980s. Seeing a creature that has been a fixture of the British countryside in decline is labeled "worrying" by experts. Toads "don't require very specific conditions" and "ought to live successfully in most of habitats in the UK," meaning if even they are struggling to persist, "it kind of suggests that the ecosystem is unbalanced."

Since 1985, Britain's toad numbers have nearly been cut in half

The Danger from Traffic

Though the research didn't examine the reasons for the decline, traffic is a major factor. Calculations indicate that 20 tons of toads are crushed 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 ability to remain away from water for longer than frogs means they can travel further to reach them – sometimes hundreds of metres. They tend to follow their traditional paths – it's common for mature amphibians to return to their birth pond to mate.

Breeding Habits

Appropriately enough, the initial amphibians start their journey for a mate around February 14th, but some move as late as April, waiting until it gets dark and moving after sunset. During that time, toads begin migrating from wherever they have been hibernating "almost simultaneously."

A local helper, who grew up in the region and has been trying to protect its amphibians since he was a child, notes that "They've got just one focus: to go and have an orgy." If their route happens to a street, they could all get run over, and that mating period would be lost – stopping a next generation of toads from being produced.

Toad Patrols Throughout the United Kingdom

Seeing hundreds of toad carcasses on local roads "resonates deeply with people," and has resulted in the formation of toad patrols throughout the UK – 274 groups are officially listed with a countrywide program. These groups collect toads and transport them across roads in containers, as well as counting the number of toads they find and advocating for other protection measures, such as road closures and underground wildlife tunnels.

Patrols tend to operate during the breeding period, when amphibian movements are more regular. However, this implies they can overlook numbers of toadlets, which, having existed as eggs and then tadpoles, exit their ponds over an irregular timetable in the end of summer. Because of their small stature – just one or two centimetres wide – "they can get obliterated by vehicles." And as being hit "essentially crushes them," it's more difficult to get data on them. At least when adult toads are killed, their remains can be counted.

Year-Round Work

In contrast to most patrols, one local team, who are in their eighth season of operating, go out year-round – not nightly, but when weather are damp, or if a member has reported about a toad sighting in their group chat. When I request to accompany them on duty, they admit it is "not a toady night" – toad hibernation season has started and it's been a arid period – but several of the volunteers gamely agree to walk up and down their area with me and see what we can find. "Should anyone can find any toads tonight, those two will find one," says the patrol manager, indicating her 14-year-old son and the experienced member. We've been out for 120 minutes without a glimpse of any amphibians, and now they have climbed over a wire barrier to inspect beneath some logs.

Family Involvement

The family duo became part of the patrol a year and a half ago. The teenager loves all things nature-related and has an goal to become a conservationist, so his mother started to look 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 decided to step up.

The youth, too, has been instrumental in the organization. A clip he created, imploring the municipal authority to close a street through a protected area during breeding time, influenced the outcome the team's way. After a twelve months of campaigning, the council agreed to an "access-only" rule between 5pm and 5am from February through to spring. The majority of motorists duly avoided the route.

Additional Species and Challenges

Several vehicles go by when I'm out on duty and we find some casualties as a consequence – no toads, but several crushed salamanders. We see one live amphibian as well, and the youngster is particularly pleased to see a harvestman, which dances in his palms. Yet in spite of the group's hardest attempts to let me see a toad, the local population has clearly settled down for the winter. It appears that I wouldn't have had any better success anywhere else in the nation – all the rescue teams I reach out to clarify that it's near-impossible at this time of year.

One email I get from a different helper, who has kindly made the effort to look for toads in a famous site, considered the largest accurately monitored toad group in the UK, arrives in my inbox with the subject line: "No toads." However, in February and March, he tells me, the team plans to assist approximately ten thousand adult toads across the road.

Impact and Challenges

What level of impact can these groups actually make? "The fact that volunteers are performing this consistently on chilly, wet and miserable late nights is remarkable," notes an expert. "That's something that very much deserves recognition." However, while toad patrols are able to slow the decline, they can't stop it completely – not least because vehicles is just one danger.

Additional Threats

The climate crisis has resulted in longer periods of dry weather, which create the wrong conditions for some of the creatures that toads eat, such as invertebrates, while warmer ponds have caused an increase of toxic plants, which can be harmful to toads. Warmer cold seasons also cause toads to wake up from their hibernation more frequently, interfering with the energy conservation vital to their existence. Loss of environment – particularly the disappearance of big water bodies – is an additional threat.

Experts are "often concerned about putting too much of a utilitarian spin on wildlife," but "It's important in just having these animals around." But toads do have an important role in the food chain, consuming almost any invertebrates or small animals they can swallow and in turn feeding a number of predators, such as wildlife. Enhancing conditions for toads – ie building water habitats, protecting forests and installing amphibian passages – "we'll improve them for a whole bunch of additional wildlife."

Historical Importance

An additional motive to work to preserve toads around is their "historical significance," adds an specialist. Legends and tales around toads date back {centuries|hundred
