Will Britain's Common Toads Survive from Traffic and Population Collapse?
It is Friday night at half past seven, but rather than heading to the pub or watching a film, I've taken a train to a town in the countryside to meet up with local helpers from a toad patrol. These committed people give up their nights to protect the native amphibian community.
An Alarming Drop in Population
The Bufo bufo is becoming increasingly rare. A latest research led by an wildlife conservation group revealed that the British common toad numbers have dropped by half since 1985. Seeing a species that has been a stalwart of the UK landscape in decrease is labeled "concerning" by experts. Toads "don't need very specific conditions" and "should be able to live successfully in most of habitats in Britain," meaning if even they are not managing to survive, "it indicates that things are not as they should be."

The Danger from Traffic
Though the study didn't examine the reasons for the drop, cars certainly plays a part. Calculations suggest that 20 tonnes of toads are crushed on UK roads annually โ in other words, several hundred thousand. Unlike frogs, which would probably be content to mate "with just a bucket of water," toads favor large ponds. Their capacity to remain away from water for more time than frogs means they can travel further to reach them โ sometimes hundreds of metres. They tend to follow their traditional paths โ it's typical for adult toads to return to their birth pond to mate.
Breeding Habits
Fittingly, the initial amphibians start their journey for a partner around February 14th, but some move as far as April, until it gets dark and travelling after sunset. During that period, toads start moving from where they have been overwintering "all pretty much at the same time."
A local helper, who grew up in the region and has been working to save its amphibians since he was a boy, notes that "They've got just one focus: to go and have an orgy." If their route crosses a road, they could be killed by traffic, and that mating period would never happen โ stopping a new generation of toads from being produced.
Toad Patrols Throughout the UK
Finding many of dead toads on local roads "inherently strikes a chord with people," and has led to the creation of rescue teams across the UK โ 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 lobbying for other protection measures, such as road closures and amphibian passages.
Patrols tend to operate during the breeding period, when toad crossings are more regular. However, this means they can overlook groups of toadlets, which, having been spawn and then juveniles, leave their ponds over an unpredictable schedule in the end of summer. Because of their small stature โ just one or two centimetres wide โ "they can get obliterated by vehicles." And as being run over "essentially crushes them," it's harder to collect information on them. At least when adult toads are lost, their remains can be counted.
Year-Round Efforts
In contrast to many groups, one local team, who are in their eighth season of functioning, go out year-round โ not nightly, but whenever conditions are damp, or if someone has posted about a amphibian spotting in their group chat. When I request to accompany them on duty, they admit it is "not ideal conditions" โ winter dormancy has begun and it's been a arid period โ but several of the helpers willingly accept to walk up and down their area with me and search for any toads. "If anyone can locate any toads tonight, those two will spot one," says the patrol manager, indicating her teenage child and the longtime volunteer. After for two hours without a single toad sighting, and now they have scaled a barbed wire fence to inspect beneath some wood.
Community Participation
The family duo became part of the group a while back. The teenager loves all things nature-related and has an goal to become a environmentalist, so his parent started to search for things they could do together to protect native animals. Now she loves it as much as he does, the middle-aged small business owner explains โ so when the team was looking for a new manager lately, she decided to step up.
The teenager, too, has played an important role in the group. A clip he made, imploring the local council to close a road through a protected area during breeding time, swung the decision the team's way. After a twelve months of lobbying, the council agreed to an "restricted access" restriction between 5pm and 5am from late winter through to April. The majority of motorists duly avoided the route.
Additional Species and Difficulties
Several cars go by when I'm out on patrol and we find some victims as a consequence โ 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 dances in his hands. Yet in spite of the team's best efforts to show me a toad, the native community has clearly settled down for the winter. It seems that I wouldn't have had any better success elsewhere in the nation โ all the patrol groups I contact explain that it's very difficult at this season.
This team anticipates assisting around ten thousand mature toads over the street
A message I get from another volunteer, who has generously made the effort to look for toads in a noted location, thought to be the biggest tracked toad population in the UK, reaches me with the subject line: "No toads." However, in late winter, he tells me, the group expects to help around ten thousand mature amphibians over the street.
Effectiveness and Limitations
What level of impact can these groups truly achieve? "The reality that volunteers are doing this regularly on cold, damp and unpleasant late nights is remarkable," notes an expert. "This effort that very much deserves recognition." However, while rescue teams are able to slow the decline, they cannot prevent it entirely โ not least because vehicles is not the only threat.
Additional Threats
The climate crisis has resulted in extended spells of drought, which cause the wrong conditions for some of the creatures that toads eat, such as worms and slugs, while warmer ponds have led to an increase of blue-green algae, which can be harmful to toads. Warmer cold seasons also lead toads to emerge from their hibernation more frequently, interfering with the energy conservation vital to their life cycle. Habitat destruction โ particularly the disappearance of big water bodies โ is another menace.
Experts are "often concerned about putting too much of a utilitarian spin on biodiversity," but "It's important in just their presence." But toads do have an important role in the ecosystem, eating almost any small creatures or small animals they can swallow and in turn sustaining a number of predators, such as hedgehogs and otters. Improving conditions for toads โ such as creating more ponds, conserving woodland and constructing amphibian passages โ "benefits for a whole bunch of other species."
Cultural Importance
Another reason to try to keep toads around is their "historical significance," notes an expert. Legends and tales around toads go back {centuries|hundred
