Will Britain's Common Toads Be Saved from Traffic and Population Collapse?
It's Friday night at half past seven, but instead of going out or relaxing at home, I've caught a train to a market town in the countryside to join local helpers from a amphibian rescue group. These dedicated individuals give up their evenings to safeguard the native amphibian community.
An Alarming Decline in Population
The common toad is becoming increasingly uncommon. A latest research led by an amphibian and reptile charity showed that the British common toad numbers have almost halved since 1985. Observing a creature 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 "should be able to live successfully in the majority of habitats in the UK," so if even they are struggling to persist, "it indicates that the ecosystem is unbalanced."

The Danger from Roads
Though the research didn't examine the reasons for the decline, cars is a major factor. Estimates suggest 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 "with just a bucket of water," toads prefer large ponds. Their capacity to remain away from water for more time than frogs allows they can journey farther to reach them – sometimes hundreds of metres. They tend to follow their traditional paths – it's common for adult toads to go back to their natal 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, waiting until it gets dark and travelling through the night. During that time, toads begin migrating from wherever they have been hibernating "almost simultaneously."
One volunteer, who was raised in the area and has been working to save its amphibians since he was a child, explains that "They've got just one focus: to go and have an orgy." If their route happens to a street, they could all get run over, and that mating period would never happen – preventing a new generation of toads from being produced.
Toad Patrols Across the United Kingdom
Seeing many of toad carcasses on local roads "inherently strikes a chord with people," and has led to the formation of toad patrols throughout the UK – hundreds of organizations are officially listed with a national initiative. These teams pick up toads and transport them over streets in buckets, as well as recording the quantity of toads they find and lobbying for other safety solutions, such as blocked roads and underground wildlife tunnels.
Volunteers usually work during the breeding period, when toad crossings are frequent. However, this implies they can overlook numbers of young toads, which, having been spawn and then tadpoles, leave their ponds over an unpredictable schedule in the end of summer. Because of their small stature – just a couple of cm wide – "they are destroyed by car traffic." And as being run over "essentially crushes them," it's more difficult to collect information on them. At least when adult toads are lost, their carcasses can be counted.
Year-Round Efforts
Unlike most patrols, one local team, who are in their eighth season of functioning, go out throughout the year – not nightly, but whenever conditions are warm and wet, or if someone has reported about a amphibian spotting in their group chat. When I request to accompany them on duty, they concede it is "not ideal conditions" – winter dormancy has begun and it's been a arid period – but several of the helpers gamely agree to walk up and down their area with me and search for any toads. "Should anyone can find any toads tonight, that pair will spot one," says the patrol manager, indicating her 14-year-old son 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 inspect beneath some logs.
Community Involvement
The mother and son joined 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 look for activities they could do jointly to protect local wildlife. Now she enjoys 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 decided to step up.
The teenager, too, has played an important role in the organization. A clip he made, urging the local council to block a road through a protected area during breeding time, swung the decision the team's way. After a year of campaigning, the council approved an "access-only" rule between evening and morning from late winter through to April. Most drivers duly avoided the route.
Additional Species and Difficulties
A few vehicles go by when I'm out on duty and we discover some casualties as a consequence – no toads, but several crushed salamanders. We see one living newt as well, and the youngster is particularly pleased to see a harvestman, which moves in his palms. Yet in spite of the group's hardest attempts to show me a toad, the local population has clearly gone dormant for the winter. It seems that I wouldn't have had any more luck elsewhere in the country – all the patrol groups I contact explain that it's near-impossible at this time of year.
This team anticipates assisting around ten thousand mature toads over the street
A message I get from another volunteer, who has kindly taken the trouble to check for toads in a noted location, considered the largest accurately monitored toad population in the UK, reaches me with the title: "No toads." However, in February and March, he informs me, the team plans to assist approximately 10,000 adult toads over the street.
Effectiveness and Challenges
What level of impact can these groups truly achieve? "The fact that volunteers are performing this consistently on cold, damp and unpleasant evenings is remarkable," says an expert. "This effort that very much should be celebrated." However, while rescue teams are able to reduce the drop, they cannot prevent it entirely – partly since traffic is just one danger.
Other Dangers
The climate crisis has meant extended spells of drought, which create the poor environment for some of the animals that toads eat, such as worms and slugs, while higher water temperatures have caused an rise of blue-green algae, which can be toxic to toads. Milder winters also lead toads to emerge from their hibernation more frequently, interfering with the energy conservation vital to their existence. Habitat destruction – particularly the loss of large ponds – is another menace.
Experts are "often concerned about overemphasizing practical benefits on wildlife," but "It's important in just their presence." But toads do have an important role in the food chain, eating pretty much any small creatures or tiny organisms they can swallow and in turn sustaining a number of predators, such as hedgehogs and otters. Enhancing conditions for toads – ie building water habitats, protecting forests and constructing amphibian passages – "benefits for a whole bunch of additional wildlife."
Historical Importance
Another reason to try to keep toads present is their "historical significance," adds an specialist. Myths and folklore around toads go back {centuries|hundred
