Can the UK's Common Toads Survive from Traffic and Terrible Decline?
It is Friday night at half past seven, but rather than heading to the pub or relaxing at home, I've caught a train to a town in the countryside to meet up with local helpers from a toad patrol. These committed people sacrifice their nights to protect the native amphibian community.
A Worrying Drop in Numbers
The common toad is becoming increasingly uncommon. A recent research conducted by an wildlife conservation group revealed that the UK toad population have dropped by half since the mid-1980s. Observing a species that has been a stalwart of the UK landscape in decrease is labeled "worrying" by researchers. Toads "don't need very particular environments" and "should be able to live quite well in the majority of areas in Britain," 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 decline, cars certainly plays a part. Estimates indicate that 20 tons of toads are crushed on British roads every year – in other words, hundreds of thousands. In contrast to frogs, which might be content to mate "if you left out a bucket of water," toads prefer large ponds. Their ability to stay out of water for more time than frogs allows they can journey farther to reach them – often long distances. They usually stick to their ancestral migration routes – it's typical for adult toads to go back to their birth pond to mate.
Breeding Patterns
Appropriately enough, the first toads start their journey for a partner around February 14th, but others travel as far as spring, until it gets night and moving after sunset. During that period, toads begin migrating from wherever they have been overwintering "all pretty much at the same time."
A local helper, who grew up in the region and has been trying to protect its amphibians since he was a boy, explains that "They've got just one focus: to go and mate." If their path happens to a street, they could all get run over, and that breeding season would be lost – stopping a new generation of toads from being produced.
Rescue Groups Across the United Kingdom
Seeing many of dead toads on nearby streets "inherently strikes a chord with people," and has resulted in the creation of toad patrols across the UK – 274 groups are currently registered with a countrywide program. These teams collect toads and carry them over streets in containers, as well as recording the number of toads they find and lobbying for other safety solutions, such as blocked roads and amphibian passages.
Patrols usually work during the migration season, when toad crossings are frequent. However, this implies they can overlook groups of toadlets, which, having existed as eggs and then juveniles, leave their ponds over an unpredictable schedule in late summer. Because of their size – just one or two centimetres wide – "they are destroyed by vehicles." 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 remains can be tallied.
Annual Work
In contrast to many groups, one local team, who are in their eighth year of operating, go out year-round – not every night, but when conditions are warm and wet, or if someone has reported about a toad sighting in their messaging app. When I request to accompany them on duty, they admit it is "not a toady night" – toad hibernation season has started and it's been a arid period – but several of the helpers willingly accept to walk up and down their route with me and search for any toads. "If anyone can locate any toads tonight, that pair will find one," says the patrol manager, indicating her 14-year-old son and the experienced member. After for two hours without a glimpse of any amphibians, and now they have scaled a barbed wire fence to inspect beneath some logs.
Family Participation
The family duo joined the group a year and a half ago. The youngster loves all things wildlife and has an goal to become a environmentalist, so his parent started to look for things they could do together to protect native animals. Now she enjoys it as much as he does, the middle-aged entrepreneur explains – so when the team was seeking a new manager lately, she decided to step up.
The youth, too, has played an important role in the group. A clip he created, urging the local council to close a street through a nature reserve during breeding time, influenced the outcome the group's way. After a year of campaigning, the authority agreed to an "access-only" restriction between evening and morning from February through to April. The majority of motorists respected and avoided the road.
Additional Species and Challenges
A few vehicles go by when I'm out on duty and we find some casualties as a consequence – no toads, but several crushed salamanders. We see one live amphibian 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 let me see a toad, the local population has clearly gone dormant for the colder months. It appears that I wouldn't have had any more luck anywhere else in the country – all the rescue teams I reach out to explain that it's near-impossible at this time of year.
The group expects to help approximately 10,000 adult toads across the road
A message I get from a different helper, who has kindly made the effort to check for toads in a noted location, considered the biggest tracked toad population in the UK, arrives in my inbox with the title: "None found." However, in late winter, he tells me, the group expects to help approximately ten thousand adult toads across the road.
Impact and Challenges
What level of impact can these groups actually make? "The reality that people are performing this consistently on chilly, wet and miserable late nights is remarkable," says an expert. "That's something that very much should be celebrated." However, while rescue teams are able to reduce the drop, they cannot prevent it entirely – not least because traffic is not the only threat.
Additional Threats
The climate crisis has resulted in extended spells of dry weather, which cause the poor environment for some of the creatures that toads consume, such as worms and slugs, while warmer ponds have led to an rise of toxic plants, which can be harmful to toads. Milder winters also lead toads to wake up from their dormancy more often, disrupting the energy conservation vital to their existence. Habitat destruction – especially the loss of big water bodies – is another menace.
Researchers are "always a bit worried about overemphasizing practical benefits on wildlife," but "It's important in just their presence." But toads play an significant part in the ecosystem, consuming almost any invertebrates or tiny organisms they can swallow and in turn sustaining a variety of birds and mammals, such as wildlife. Improving conditions for toads – ie creating more ponds, conserving woodland and constructing amphibian passages – "we'll improve them for a whole bunch of additional wildlife."
Cultural Importance
Another reason to work to preserve toads around is their "important cultural value," adds an expert. Myths and folklore around toads go back {centuries|hundred
