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

It's a Friday evening at 7:30, but instead of going out or watching a film, I've taken a train to a town in the countryside to join local helpers from a amphibian rescue group. These dedicated individuals give up their evenings to protect the local toad population.

A Worrying Decline in Numbers

The common toad is becoming increasingly rare. A recent research led by an wildlife conservation group showed that the UK toad population have almost halved since the mid-1980s. Seeing a species that has been a stalwart of the UK landscape in decrease is labeled "concerning" by experts. Toads "don't need very particular environments" and "should be able to live successfully in most of habitats in the UK," so if even they are struggling to persist, "it kind of suggests that things are not as they should be."

Toad populations across the UK have declined by almost 50% since the 1980s

The Danger from Roads

Though the study didn't cover the reasons for the decline, traffic is a major factor. Calculations indicate that 20 tonnes of toads are crushed on UK roads every year – that is, hundreds of thousands. In contrast to frogs, which might be happy to mate "with just a bucket of water," toads favor large ponds. Their capacity to remain away from water for more time than frogs allows they can journey farther to find them – often long distances. They usually stick to their ancestral migration routes – it's common for mature amphibians to go back to their birth pond to mate.

Migration Patterns

Fittingly, the first toads begin their quest for a mate around February 14th, but others travel as far as April, waiting until it gets night and moving through the night. During that period, toads start moving from where they have been hibernating "almost simultaneously."

One volunteer, who grew up in the region and has been trying to protect its amphibians since he was a boy, notes that "They've got just one focus: to go and mate." If their path crosses a street, they could all get run over, and that mating period would be lost – preventing a new generation of toads from being produced.

Rescue Groups Across the United Kingdom

Seeing many of toad carcasses on local roads "inherently strikes a chord with people," and has resulted in the creation of rescue teams across the UK – 274 groups are currently registered with a national initiative. These groups pick up toads and transport them across roads in buckets, as well as recording the quantity of toads they find and advocating for other protection measures, such as blocked roads and amphibian passages.

Volunteers usually work during the migration season, when amphibian movements are more regular. However, this implies they can overlook groups of toadlets, which, having been eggs and then tadpoles, leave their water habitats over an unpredictable schedule in the end of summer. Because of their size – just one or two centimetres wide – "they can get obliterated by car traffic." And as being hit "basically turns them into mush," it's more difficult to collect information on them. At least when adult toads are lost, their carcasses can be counted.

Year-Round Work

Unlike most patrols, one local team, who are in their eighth year of operating, go out year-round – not every night, but whenever weather are warm and wet, or if a member has posted about a toad sighting in their group chat. When I request to accompany them on patrol, they concede it is "not ideal conditions" – toad hibernation season has begun and it's been a arid period – but several of the volunteers gamely agree to walk up and down their area with me and search for any toads. "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. After for two hours without a glimpse of any amphibians, and now they have climbed over a wire barrier to inspect beneath some wood.

Community Involvement

The family duo joined the group a year and a half ago. The youngster adores all things nature-related and has an goal to become a conservationist, so his parent started to search for things they could do jointly to protect local wildlife. Now she enjoys it as much as he does, the middle-aged entrepreneur explains – so when the group was seeking a fresh coordinator recently, she decided to step up.

The teenager, too, has been instrumental in the group. A clip he made, imploring the municipal authority to block a road through a nature reserve during breeding time, influenced the outcome the group's way. After a year of lobbying, the authority approved an "restricted access" rule between 5pm and 5am from February through to April. The majority of motorists respected and avoided the route.

Additional Species and Difficulties

A few cars go past when I'm out on duty and we discover some victims as a consequence – no toads, but three squashed newts. We see one living newt as well, and the youngster is particularly pleased 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 colder months. It appears that I wouldn't have had any better success anywhere else in the nation – all the rescue teams I contact clarify that it's near-impossible at this season.

One email I receive from another volunteer, who has kindly taken the trouble to check for toads in a famous site, considered the largest accurately monitored toad population in the UK, arrives in my inbox with the title: "No toads." However, in late winter, he informs me, the team plans to assist around ten thousand mature amphibians across the road.

Effectiveness and Limitations

What level of impact can these groups actually make? "The fact that people are performing this consistently on cold, damp and unpleasant late nights is remarkable," notes an researcher. "That's something that very much deserves recognition." However, while toad patrols are able to slow the decline, they cannot prevent it entirely – partly since traffic is just one danger.

Additional Threats

The global warming has resulted in extended spells of drought, which cause the poor environment for some of the creatures that toads consume, such as invertebrates, while warmer ponds have caused an rise of toxic plants, which can be toxic to toads. Warmer cold seasons also cause toads to wake up from their dormancy more frequently, disrupting the energy conservation vital to their existence. Loss of environment – especially the loss of big water bodies – is another menace.

Experts are "always a bit worried about putting too much of a utilitarian spin on biodiversity," but "It's important in just having these animals around." But toads play an significant part in the food chain, eating almost any invertebrates or tiny organisms they can fit in their mouths and in turn sustaining a variety of predators, such as wildlife. Improving situations for toads – ie building water habitats, conserving woodland and constructing amphibian passages – "we'll improve them for a whole bunch of other species."

Cultural Importance

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