Can Britain's Toads Survive from Traffic and Terrible Decline?
It is Friday evening at half past seven, but rather than heading to the pub or relaxing at home, I've taken a train to a market town in the countryside to meet up with local helpers from a toad patrol. These dedicated individuals sacrifice their nights to protect 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 the mid-1980s. Seeing a species that has been a fixture of the UK landscape in decrease is described as "concerning" by researchers. Toads "don't require very specific conditions" and "ought to live quite well in the majority of areas in the UK," meaning if even they are struggling to persist, "it kind of suggests that the ecosystem is unbalanced."

The Threat from Roads
Though the study didn't cover the reasons for the decline, cars certainly plays a part. Estimates suggest that 20 tonnes of toads are killed on British roads every year – that is, several hundred thousand. In contrast to 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 journey farther to reach them – often long distances. They tend to stick to their ancestral migration routes – it's common for adult toads to return to their birth pond to mate.
Migration Patterns
Fittingly, the initial amphibians start their journey for a partner around Valentine's day, but others travel as far as spring, until it gets dark and travelling after sunset. During that time, toads start moving from wherever they have been overwintering "all pretty much at the same time."
One volunteer, who was raised in the region and has been working to save its toad population since he was a boy, explains that "They've got just one focus: to go and have an orgy." If their route happens to a road, they could be killed by traffic, and that breeding season would never happen – preventing a new generation of toads from being born.
Toad Patrols Across the UK
Seeing hundreds of dead toads on nearby streets "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 over streets in containers, as well as counting the quantity of toads they encounter and lobbying for other safety solutions, such as blocked roads and underground wildlife tunnels.
Patrols tend to operate during the migration season, when amphibian movements are frequent. However, this implies they can miss groups of toadlets, which, having existed as spawn and then tadpoles, leave their ponds over an irregular timetable in the end of summer. Because of their small stature – just a couple of cm wide – "they are destroyed by vehicles." And as being hit "basically turns them into mush," it's harder to collect information on them. At least when adult toads are lost, their remains can be counted.
Annual Efforts
In contrast to many groups, one local team, who are in their eighth year of functioning, go out throughout the year – not nightly, but whenever conditions are damp, or if someone has reported about a toad sighting 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 dry day – but several of the volunteers willingly accept to patrol their route with me and search for any toads. "Should anyone can find any toads tonight, those two will find one," says the patrol manager, pointing to 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 wood.
Family Involvement
The mother and son joined the patrol a year and a half ago. The youngster adores all things wildlife and has an ambition to become a environmentalist, so his mother started to search for things they could do together to protect local wildlife. Now she loves it as much as he does, the middle-aged small business owner tells me – so when the group was looking for a fresh coordinator lately, she volunteered for the role.
The youth, too, has played an important role in the organization. A video he created, imploring the local council to block a road through a protected area during migration season, influenced the outcome the group's way. After a twelve months of campaigning, the authority approved an "access-only" restriction between evening and morning from February through to April. The majority of motorists duly avoided the road.
Additional Species and Difficulties
A few vehicles go by when I'm out on patrol and we discover some casualties as a result – no toads, but three squashed newts. We spot one live amphibian as well, and the teenager is particularly pleased to see a harvestman, which dances in his palms. Yet despite the team's best efforts to show me a toad, the native community has clearly gone dormant for the colder months. It appears that I wouldn't have had any more luck elsewhere in the nation – all the patrol groups I reach out to explain that it's very difficult at this time of year.
They project rescuing nearly 10,000 grown amphibians during migration
One email I get from a different helper, who has generously taken the trouble to check for toads in a noted location, considered the biggest tracked toad population in the UK, arrives in my inbox with the subject line: "None found." However, in February and March, he informs me, the group plans to assist approximately 10,000 mature amphibians over the street.
Effectiveness and Limitations
What level of impact can these groups truly achieve? "The fact that people are doing this consistently on cold, damp and unpleasant evenings 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 – partly since traffic is just one danger.
Other Dangers
The global warming has meant extended spells of dry weather, which create the poor environment for some of the animals that toads consume, such as invertebrates, while warmer ponds have caused an increase of blue-green algae, which can be harmful to toads. Warmer cold seasons also lead toads to wake up from their dormancy more frequently, disrupting the resource preservation crucial to their existence. Loss of environment – especially the loss of big water bodies – is another menace.
Experts are "often concerned about putting too much of a utilitarian spin on wildlife," however "It's important in just their presence." But toads do have an important role in the food chain, consuming almost any small creatures or small animals they can fit in their mouths and in turn feeding a number of predators, such as wildlife. Enhancing conditions for toads – ie building water habitats, conserving woodland and installing amphibian passages – "benefits for a wide range of other species."
Historical Importance
Another reason to try to keep toads present is their "historical significance," notes an expert. Legends and tales around toads go back {centuries|hundred
