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

It is a Friday evening at half past seven, but instead of going out or relaxing at home, I've caught a train to a town in Wiltshire to join local helpers from a toad patrol. These committed people sacrifice their nights to safeguard the local toad population.

An Alarming Drop in Numbers

The Bufo bufo is growing more uncommon. A recent research led by an amphibian and reptile charity showed that the British common toad numbers have almost halved since the mid-1980s. Observing a creature that has been a stalwart of the British countryside in decline is described as "concerning" by researchers. Toads "don't need very specific conditions" and "should be able to live successfully in most of areas in Britain," so if even they are not managing to survive, "it kind of suggests that the ecosystem is unbalanced."

The Threat from Roads

Though the study didn't cover the causes for the drop, traffic is a major factor. Calculations indicate that 20 tonnes of toads are killed on British roads annually – that is, hundreds of thousands. In contrast to frogs, which would probably be content to mate "with just a bucket of water," toads favor big bodies of water. Their ability to remain away from water for more time than frogs allows they can travel further to find them – sometimes long distances. They tend to follow their traditional paths – it's typical for mature amphibians to return to their birth pond to mate.

Migration Patterns

Appropriately enough, the first toads start their journey for a partner around Valentine's day, but others travel as far as April, until it gets dark and moving after sunset. During that period, toads begin migrating from where they have been hibernating "all pretty much at the same time."

One volunteer, who grew up in the area and has been working to save its amphibians since he was a child, explains that "They've got just one focus: to go and mate." If their path happens to a road, they could be killed by traffic, and that breeding season would never happen – stopping a new generation of toads from being born.

Rescue Groups Throughout the United Kingdom

Seeing hundreds of dead toads on nearby streets "inherently strikes a chord with people," and has resulted in the formation of rescue teams across the UK – 274 groups are currently registered with a countrywide program. These groups pick up toads and transport them across roads in containers, as well as recording the number of toads they find and advocating for other safety solutions, such as blocked roads and underground wildlife tunnels.

Volunteers usually work during the breeding period, when amphibian movements are frequent. However, this means they can overlook groups of toadlets, which, having been spawn 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 are destroyed by car traffic." And as being run over "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 functioning, go out year-round – not nightly, but whenever weather are damp, or if someone has reported about a amphibian spotting in their group chat. When I ask to join them on duty, they admit it is "not a toady night" – toad hibernation season has begun and it's been a dry day – but several of the helpers willingly accept to walk up and down their area with me and search for any toads. "If anyone can find any toads tonight, those two will find one," says the group coordinator, pointing to her teenage child and the longtime volunteer. After for 120 minutes without a single toad sighting, and now they have scaled a wire barrier to inspect beneath some logs.

Family Involvement

The family duo joined the group a while back. The teenager adores all things wildlife and has an ambition to become a conservationist, so his mother started to look for things they could do together to help local wildlife. Now she loves it as much as he does, the middle-aged entrepreneur explains – so when the team was looking for a new manager recently, she decided to step up.

The teenager, too, has been instrumental in the organization. A video he made, imploring the municipal authority to close a road through a nature reserve during migration season, swung the decision the group's way. After a twelve months of campaigning, the council approved an "access-only" rule between evening and morning from late winter through to spring. The majority of motorists duly avoided the road.

Additional Species and Challenges

Several cars go by when I'm out on duty and we find some casualties as a consequence – no amphibians, but several crushed salamanders. We see one live amphibian as well, and the youngster is particularly pleased to see a harvestman, which moves in his palms. Yet despite the group's best efforts to let me see a toad, the native community has clearly settled down for the colder months. It seems that I wouldn't have had any better success elsewhere in the nation – all the rescue teams I contact explain that it's very difficult at this season.

A message I get from a different helper, who has kindly made the effort to look for toads in a noted location, thought to be the biggest tracked toad population in the UK, arrives in my inbox with the subject line: "No toads." However, in February and March, he informs me, the group expects to help around 10,000 adult toads over the street.

Impact and Limitations

How much of a difference can these groups truly achieve? "The reality that people are doing this consistently on cold, damp and unpleasant late nights 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 can't stop it completely – not least because traffic is not the only threat.

Other Dangers

The climate crisis has meant longer periods of dry weather, which cause the wrong conditions for some of the creatures that toads consume, such as invertebrates, while warmer ponds have led to an rise of blue-green algae, 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 crucial to their life cycle. Habitat destruction – especially the loss of large ponds – is an additional threat.

Researchers are "often concerned about putting too much of a utilitarian spin on wildlife," but "There is a big value in just their presence." But toads do have an important role in the ecosystem, consuming pretty much any small creatures or small animals they can swallow and in turn feeding a variety of predators, such as hedgehogs and otters. Improving conditions for toads – ie creating more ponds, protecting forests and constructing amphibian passages – "we'll improve them for a wide range of additional wildlife."

Cultural Significance

Another reason to work to preserve toads present is their "historical significance," notes an expert. Legends and tales around toads date back {centuries|hundred
