Will Britain's Common Toads Be Saved from Roads and Population Collapse?
It is a Friday night at 7:30, but rather than going out or relaxing at home, I've taken a train to a town in the countryside to join volunteers from a toad patrol. These dedicated individuals sacrifice their evenings to safeguard the local toad population.
A Worrying Drop in Numbers
The Bufo bufo is growing more rare. A latest research conducted by an wildlife conservation group showed that the British common toad numbers have dropped by half since the mid-1980s. Observing a species that has been a fixture of the UK landscape in decrease is described as "worrying" by researchers. Toads "don't need very particular environments" and "ought to live successfully in the majority of habitats in Britain," so if even they are not managing to survive, "it kind of suggests that things are not as they should be."

The Danger from Traffic
Though the research didn't examine the causes for the drop, traffic certainly plays a part. Calculations suggest that 20 tonnes of toads are killed on British roads annually – in other words, several hundred thousand. In contrast to frogs, which would probably be content 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 journey farther to reach them – sometimes long distances. They tend to follow their traditional paths – it's typical for mature amphibians to go back to their birth pond to mate.
Breeding Habits
Appropriately enough, the first toads begin their quest for a mate around February 14th, but others travel as late as spring, until it gets night and moving after sunset. During that time, toads start moving from where 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 child, explains that "They've got just one focus: to go and have an orgy." If their route crosses a road, they could all get run over, and that mating period would be lost – stopping a new generation of toads from being produced.
Toad Patrols Across the UK
Seeing many of toad carcasses 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 countrywide program. These teams collect toads and carry them across roads in containers, as well as counting the number 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 eggs and then tadpoles, exit their ponds over an unpredictable schedule in the end of summer. Because of their size – just one or two centimetres wide – "they are destroyed by car traffic." And as being hit "essentially crushes them," it's more difficult to collect information on them. At least when adult toads are lost, their carcasses can be counted.
Annual Efforts
In contrast to many groups, one local team, who are in their eighth season 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 messaging app. When I request to accompany them on patrol, they admit it is "not a toady night" – winter dormancy has begun and it's been a arid period – but several of the helpers willingly accept to patrol their route with me and search for any toads. "Should anyone can locate any toads tonight, those two will spot one," says the patrol manager, pointing to her 14-year-old son and the longtime volunteer. After for 120 minutes without a glimpse of any amphibians, and now they have scaled a barbed wire fence to check under some logs.
Family Participation
The family duo joined the patrol a while back. The youngster adores all things nature-related and has an goal to become a conservationist, so his mother started to look for things they could do jointly to protect native animals. Now she enjoys it as much as he does, the middle-aged entrepreneur tells me – so when the group was looking for a fresh coordinator recently, she volunteered for the role.
The youth, too, has played an important role in the group. A clip he made, urging the local council to block a road through a protected area during breeding time, influenced the outcome the team's way. After a year of lobbying, the council approved an "restricted access" restriction between 5pm and 5am from late winter through to spring. The majority of motorists respected and avoided the road.
Other Wildlife and Challenges
Several vehicles go by when I'm out on patrol and we find some victims as a result – no toads, but three squashed newts. We spot one live amphibian as well, and the youngster is particularly pleased to see a harvestman, which moves in his hands. Yet despite the group's best efforts to let me see a toad, the native community has obviously settled down for the colder months. It appears that I couldn't have found any better success anywhere else in the country – all the patrol groups I reach out to clarify that it's near-impossible at this time of year.

A message I get from a different helper, who has generously made the effort to check for toads in a noted location, thought to be the biggest tracked toad group in the UK, arrives in my inbox with the title: "None found." However, in February and March, he informs me, the team expects to help around ten thousand adult toads across the road.
Impact and Limitations
How much of a difference can these organizations truly achieve? "The reality that people are doing this consistently on chilly, wet and miserable evenings is quite extraordinary," says an expert. "That's something that very much should be celebrated." However, while toad patrols are able to reduce the drop, they can't stop it completely – not least because vehicles is not the only threat.
Additional Threats
The climate crisis has resulted in extended spells of drought, which create the poor environment for some of the creatures that toads eat, such as worms and slugs, while higher water temperatures have led to an increase of toxic plants, which can be toxic to toads. Warmer cold seasons also cause toads to wake up from their hibernation more often, disrupting the energy conservation crucial to their existence. Habitat destruction – especially the disappearance of big water bodies – is another menace.
Researchers are "often concerned about putting too much of a utilitarian spin on wildlife," however "There is a big value in just having these animals around." But toads play an important role in the food chain, consuming almost any invertebrates or tiny organisms they can fit in their mouths and in turn feeding a variety of predators, such as hedgehogs and otters. Improving conditions for toads – such as building water habitats, protecting forests and installing amphibian passages – "we'll improve them for a wide range of additional wildlife."
Historical Significance
An additional motive to work to preserve toads around is their "historical significance," notes an expert. Myths and folklore around toads go back {centuries|hundred
