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

It is a Friday evening at 7:30, but rather than going out or watching a film, I've taken a train to a town in the countryside to join local helpers 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 growing more rare. A latest research conducted by an amphibian and reptile charity revealed that the British common toad numbers have dropped by half since 1985. Observing a species that has been a stalwart of the British countryside in decrease is labeled "worrying" by researchers. Toads "don't require very particular environments" and "ought to live successfully in most of areas in Britain," so if even they are struggling to persist, "it indicates that the ecosystem is unbalanced."

The Threat from Traffic

Though the research didn't examine the causes for the drop, cars is a major factor. Calculations suggest that 20 tons of toads are killed on UK roads annually – in other words, several hundred thousand. Unlike frogs, which might be content to mate "if you left out a small container," toads favor large ponds. Their ability to remain away from water for more time than frogs allows they can travel further to find them – sometimes hundreds of metres. They tend to stick to their traditional paths – it's common for mature amphibians to return to their natal pond to mate.

Breeding Habits

Appropriately enough, the initial amphibians begin their quest for a mate around February 14th, but some move as late as spring, until it gets dark and travelling through the night. During that period, toads start moving from where they have been hibernating "almost simultaneously."

A local helper, who was raised in the region and has been trying to protect its toad population since he was a boy, notes that "They've got just one focus: to go and have an orgy." If their path happens to a road, they could all get run over, and that breeding season would be lost – stopping a next generation of toads from being born.

Rescue Groups Across the United Kingdom

Seeing hundreds of toad carcasses on local roads "resonates deeply with people," and has resulted in the creation of toad patrols throughout the UK – hundreds of organizations are currently registered with a national initiative. These groups pick up toads and transport them across roads in buckets, as well as recording the number of toads they encounter and advocating for other safety solutions, such as road closures and amphibian passages.

Patrols usually work during the breeding period, when amphibian movements are frequent. However, this implies they can miss numbers of toadlets, which, having been spawn and then juveniles, exit their ponds over an irregular timetable in late summer. Because of their small stature – just one or two centimetres wide – "they are destroyed by vehicles." And as being hit "essentially crushes them," it's more difficult to collect information on them. At least when adult toads are lost, their remains can be tallied.

Year-Round Efforts

Unlike many groups, a specific volunteer group, who are in their eighth year of operating, go out throughout the year – not nightly, but when weather are warm and wet, or if a member has posted about a amphibian spotting in their group chat. When I ask to join them on patrol, they admit it is "not a toady night" – toad hibernation season has begun and it's been a arid period – but a few of the volunteers gamely agree to walk up and down their route with me and see what we can find. "If anyone can locate any toads tonight, those two will find one," says the patrol manager, pointing to her teenage child and the longtime volunteer. We've been out for 120 minutes without a single toad sighting, and now they have scaled a barbed wire fence to inspect beneath some wood.

Community Involvement

The mother and son became part of the group a while back. The teenager loves all things wildlife and has an ambition to become a environmentalist, so his parent started to look for activities they could do together to protect local wildlife. Now she enjoys it as much as he does, the 41-year-old small business owner explains – so when the group was seeking a new manager lately, she decided to step up.

The teenager, too, has played an important role in the group. A clip he created, urging the local council to block a road through a protected area during migration season, influenced the outcome the team's way. After a year of campaigning, the council approved an "access-only" rule between 5pm and 5am from February through to April. Most drivers duly avoided the route.

Additional Species and Challenges

A few vehicles go by when I'm out on patrol and we discover some victims as a result – no toads, but three squashed newts. We see one living newt as well, and the youngster is particularly pleased to see a daddy longlegs, which moves in his palms. Yet despite the team's hardest attempts to show me a toad, the native community has obviously gone dormant for the winter. It seems that I wouldn't have had any better success anywhere else in the country – all the rescue teams I reach out to explain that it's very difficult at this season.

One email I get from a different helper, who has kindly made the effort to look for toads in a noted location, thought to be the largest accurately monitored toad group in the UK, reaches me with the subject line: "None found." However, in February and March, he tells me, the group expects to help approximately 10,000 mature amphibians over the street.

Impact and Limitations

How much of a difference can these organizations actually make? "The fact that volunteers are doing this consistently on chilly, wet and miserable late nights is quite extraordinary," notes an researcher. "This effort that very much should be celebrated." However, while rescue teams are able to reduce the drop, they can't stop it completely – not least because traffic is not the only threat.

Other Dangers

The global warming has meant extended spells of drought, which create the poor environment for some of the animals that toads eat, such as worms and slugs, while warmer ponds have led to an rise of blue-green algae, which can be toxic to toads. Warmer cold seasons also cause toads to emerge from their hibernation more often, interfering with the resource preservation vital to their existence. Habitat destruction – particularly the loss of large ponds – is an additional threat.

Researchers are "always a bit worried about overemphasizing practical benefits on biodiversity," however "There is a big value in just their presence." But toads play an important role in the ecosystem, eating almost any small creatures or tiny organisms 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 installing toad tunnels – "we'll improve them for a wide range of other species."

Historical Significance

An additional motive to work to preserve toads present is their "historical significance," notes an expert. Myths and folklore around toads go back {centuries|hundred
