Can Britain's Toads Survive from Roads and Population Collapse?
It is a Friday evening at 7:30, but rather than going out or watching a film, I've caught a train to a market town in the countryside to meet up with local helpers from a toad patrol. These dedicated individuals give up their evenings to safeguard the local toad population.
A Worrying Decline in Numbers
The common toad is becoming increasingly uncommon. A latest study conducted by an amphibian and reptile charity showed that the UK toad population have almost halved since 1985. Observing a creature that has been a stalwart of the British countryside in decline is described as "worrying" by experts. Toads "don't require very specific conditions" and "ought to live quite well in the majority of habitats in the UK," so if even they are not managing to survive, "it indicates that things are not as they should be."

The Danger from Roads
Though the research didn't cover the causes for the drop, cars certainly plays a part. Estimates suggest that 20 tons of toads are crushed on UK roads annually – in other words, hundreds of thousands. Unlike frogs, which might be happy to mate "if you left out a small container," toads prefer large ponds. Their ability to remain away from water for more time than frogs allows they can travel further to find them – often hundreds of metres. They usually follow their ancestral migration routes – it's common for adult toads to go back to their natal pond to mate.
Breeding Habits
Appropriately enough, the first toads start their journey for a partner around Valentine's day, but some move as far as April, waiting until it gets night and moving through the night. During that period, toads start moving from wherever they have been hibernating "all pretty much at the same time."
A local helper, who grew up in the region and has been working to save its toad population since he was a child, notes that "They've got just one focus: to go and have an orgy." If their path happens to a street, they could all get run over, and that mating period would be lost – stopping a new generation of toads from being produced.
Toad Patrols Throughout the UK
Seeing hundreds of dead toads on local roads "resonates deeply with people," and has led to the formation of rescue teams throughout the UK – hundreds of organizations are currently registered with a countrywide program. These teams pick up toads and carry them over streets in containers, as well as counting the quantity of toads they encounter and advocating for other safety solutions, such as blocked roads and underground wildlife tunnels.
Volunteers tend to operate during the breeding period, when toad crossings are frequent. However, this implies they can overlook numbers of young toads, which, having existed as spawn and then juveniles, leave their water habitats over an irregular timetable in late summer. Because of their size – just one or two centimetres wide – "they can get obliterated by car traffic." And as being run over "basically turns them into mush," it's harder to collect information on them. At least when adult toads are lost, their remains can be tallied.
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 when weather are warm and wet, or if a member has posted about a toad sighting in their messaging app. When I ask to join them on patrol, they concede it is "not ideal conditions" – winter dormancy has started and it's been a arid period – but several of the helpers gamely agree to patrol their route with me and see what we can find. "If anyone can locate any toads tonight, that pair will find one," says the patrol manager, pointing to her teenage child and the longtime volunteer. After for two hours without a glimpse of any amphibians, and now they have climbed over a barbed wire fence to check under some wood.
Family Involvement
The family duo became part of the patrol a while back. The youngster loves all things nature-related and has an ambition to become a environmentalist, so his mother started to search for things they could do jointly to help native animals. Now she enjoys it as much as he does, the middle-aged small business owner tells me – so when the team was seeking a new manager lately, she decided to step up.
The teenager, too, has been instrumental in the organization. A video he created, urging the local council to close a street through a protected area during migration season, influenced the outcome the group's way. After a year of campaigning, the council approved an "access-only" restriction between evening and morning from February through to April. The majority of motorists duly avoided the route.
Other Wildlife and Difficulties
A few vehicles go by when I'm out on patrol and we discover some victims as a result – no amphibians, but several crushed salamanders. We spot one living newt as well, and the teenager is particularly pleased to see a daddy longlegs, which dances in his hands. Yet despite the team's hardest attempts to show me a toad, the local population has clearly gone dormant for the colder months. It appears that I couldn't have found any better success elsewhere in the country – all the rescue teams I reach out to clarify that it's very difficult at this season.
The group expects to help approximately 10,000 adult toads across the road
A message I get from a different helper, who has generously taken the trouble to check for toads in a noted location, considered the largest accurately monitored toad group in the UK, reaches me with the subject line: "None found." However, in late winter, he informs me, the group plans to assist approximately ten thousand mature amphibians across the road.
Effectiveness and Challenges
How much of a difference can these groups truly achieve? "The reality that people are performing this regularly on cold, damp and unpleasant late nights is remarkable," says an researcher. "This effort that very much should be celebrated." However, while rescue teams are able to slow the decline, they can't stop it completely – partly since traffic is not the only threat.
Additional Threats
The global warming has meant extended spells of drought, which cause the poor environment for some of the creatures that toads eat, such as worms and slugs, while warmer ponds have led to an increase of toxic plants, which can be harmful to toads. Warmer cold seasons also lead toads to emerge from their hibernation more often, interfering with the resource preservation crucial to their life cycle. Habitat destruction – particularly the disappearance of large ponds – is another menace.
Experts are "often concerned about putting too much of a utilitarian spin on biodiversity," however "There is a big value in just their presence." But toads do have an important role in the ecosystem, eating almost any invertebrates or tiny organisms they can swallow and in turn sustaining a variety of predators, such as hedgehogs and otters. Improving conditions for toads – such as creating more ponds, protecting forests and constructing amphibian passages – "benefits for a whole bunch of additional wildlife."
Historical Significance
Another reason to work to preserve toads around is their "important cultural value," adds an expert. Legends and tales around toads go back {centuries|hundred
