Can the UK's Common Toads Survive from Traffic and Terrible Decline?
It's Friday evening at half past seven, but rather than going out or relaxing at home, I've taken a train to a market town in the countryside to join volunteers from a toad patrol. These dedicated individuals give up their nights to safeguard the local toad population.
A Worrying Decline in Population
The Bufo bufo is becoming increasingly uncommon. A latest study led by an amphibian and reptile charity showed 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 experts. Toads "don't require very specific conditions" and "ought to live quite well in the majority of areas in Britain," meaning if even they are not managing to survive, "it kind of suggests that things are not as they should be."
Toad populations across the UK have declined by almost 50% since the 1980s
The Danger from Traffic
Though the study didn't cover the causes for the decline, traffic certainly plays a part. Calculations indicate that 20 tons of toads are crushed on British roads every year – that is, several hundred thousand. In contrast to frogs, which would probably be happy to mate "with just a bucket of water," toads prefer large ponds. Their capacity to stay out of water for longer than frogs means they can journey farther to reach them – sometimes hundreds of metres. They tend to stick to their ancestral migration routes – it's common for adult toads to go back to their natal pond to mate.
Migration Patterns
Fittingly, the first toads start their journey for a partner around Valentine's day, but some move as late as spring, waiting until it gets dark and travelling after sunset. During that time, toads begin migrating from wherever they have been hibernating "almost simultaneously."
One volunteer, who grew up in the area 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 route crosses a street, they could all get run over, and that breeding season would never happen – preventing a next generation of toads from being born.
Toad Patrols Across the UK
Seeing hundreds of toad carcasses on local roads "inherently strikes a chord with people," and has resulted in the creation of toad patrols across the UK – hundreds of organizations are currently registered with a countrywide program. These groups collect toads and transport them over streets in buckets, as well as counting the number of toads they find and advocating for other safety solutions, such as blocked roads and underground wildlife tunnels.
Patrols usually work during the migration season, when toad crossings are more regular. However, this implies they can overlook groups of toadlets, which, having been eggs and then tadpoles, exit their water habitats over an unpredictable schedule in late summer. Because of their small stature – just one or two centimetres wide – "they are destroyed by car traffic." And as being run over "basically turns them into mush," it's harder to get data on them. At least when adult toads are lost, their carcasses can be counted.
Year-Round Efforts
In contrast to many groups, a specific volunteer group, who are in their eighth season of operating, go out year-round – not nightly, but when conditions are warm and wet, or if a member has reported about a toad sighting in their messaging app. When I request to accompany 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 helpers willingly accept to patrol their route with me and see what we can find. "If anyone can find any toads tonight, that pair will spot 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 climbed over a barbed wire fence to check under some wood.
Family Participation
The family duo joined the patrol a year and a half ago. The youngster loves all things wildlife and has an ambition to become a conservationist, so his parent started to search for things they could do together to protect local wildlife. Now she loves it as much as he does, the 41-year-old small business owner explains – so when the team was seeking a new manager recently, she volunteered for the role.
The youth, too, has played an important role in the organization. A video he made, imploring the local council to block a road through a nature reserve during breeding time, influenced the outcome the team'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 respected and avoided the route.
Other Wildlife and Challenges
A few cars go past 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 especially excited to see a harvestman, which moves in his palms. Yet despite the group's best efforts to show me a toad, the local population has obviously settled down for the colder months. It seems that I wouldn't have had any better success anywhere else in the nation – all the patrol groups I reach out to clarify 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 receive from a different helper, who has kindly taken the trouble to check for toads in a famous site, considered the largest accurately monitored toad group in the UK, arrives in my inbox with the subject line: "None found." However, in February and March, he informs me, the team plans to assist around 10,000 mature amphibians over the street.
Impact and Limitations
What level of impact can these organizations truly achieve? "The reality that people are doing this regularly on chilly, wet and miserable late nights is remarkable," notes an expert. "That's something that very much should be celebrated." However, while rescue teams are able to slow the decline, they cannot prevent it entirely – partly since vehicles is just one danger.
Other Dangers
The climate crisis has resulted in extended spells of drought, which cause the wrong conditions for some of the creatures that toads consume, such as worms and slugs, while warmer ponds have led to an increase of blue-green algae, which can be toxic to toads. Milder winters also lead toads to wake up from their dormancy more frequently, interfering with the resource preservation vital to their life cycle. Loss of environment – especially the disappearance of large ponds – is an additional threat.
Experts are "often concerned about overemphasizing practical benefits on biodiversity," but "It's important in just having these animals around." But toads play an important role in the food chain, eating almost any small creatures or small animals they can fit in their mouths and in turn sustaining a number of predators, such as wildlife. Enhancing conditions for toads – such as creating more ponds, protecting forests and installing toad tunnels – "we'll improve them for a wide range of additional wildlife."
Historical Importance
Another reason to work to preserve toads present is their "historical significance," adds an specialist. Legends and tales around toads go back {centuries|hundred
