Can the UK's Toads Be Saved from Roads and Population Collapse?
It's a Friday night at 7:30, but rather than heading to the pub or relaxing at home, I've taken a train to a market town in Wiltshire to meet up with volunteers from a toad patrol. These dedicated individuals give up their nights to protect the local toad population.
A Worrying Decline in Numbers
The common toad is growing more rare. A recent study conducted by an wildlife conservation group revealed that the UK toad population have dropped by half since 1985. Seeing a creature that has been a stalwart of the UK landscape in decline is labeled "worrying" by researchers. Toads "don't need very particular environments" and "should be able to live quite well in most of habitats in Britain," meaning if even they are not managing to survive, "it kind of suggests that things are not as they should be."

The Threat from Roads
Though the research didn't examine the causes for the drop, cars certainly plays a part. Estimates suggest that 20 tons 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 "if you left out a bucket of water," toads prefer big bodies of water. Their ability to stay out of water for more time than frogs allows they can journey farther to find them – often long distances. They usually stick to their traditional paths – it's common for adult toads to return to their birth pond to mate.
Breeding Habits
Fittingly, the first toads begin their quest for a partner around Valentine's day, but some move as late as April, until it gets dark and moving after sunset. During that time, toads begin migrating from wherever they have been hibernating "almost simultaneously."
One volunteer, who was raised in the region and has been trying to protect its amphibians since he was a boy, explains that "Their sole purpose: to go and mate." If their route crosses a road, they could be killed by traffic, and that mating period would never happen – stopping a next generation of toads from being produced.
Rescue Groups Across the United Kingdom
Seeing hundreds of dead toads on nearby streets "resonates deeply with people," and has led to the creation of rescue teams throughout the UK – hundreds of organizations are currently registered with a national initiative. These groups collect toads and transport them across roads in containers, as well as recording the number of toads they find and lobbying for other protection measures, such as road closures and amphibian passages.
Volunteers tend to operate during the migration season, when toad crossings are more regular. However, this implies they can overlook numbers of toadlets, which, having existed as eggs and then juveniles, leave their water habitats over an unpredictable schedule in late summer. Because of their size – just one or two centimetres wide – "they can get obliterated by car traffic." And as being hit "basically turns them into mush," it's more difficult to collect information on them. At least when adult toads are killed, their remains can be tallied.
Year-Round Efforts
In contrast to many groups, a specific volunteer group, who are in their eighth year of operating, go out year-round – not nightly, but whenever conditions are warm and wet, or if someone has reported about a toad sighting in their group chat. When I ask to join them on duty, they admit it is "not ideal conditions" – toad hibernation season has started and it's been a arid period – but a few of the helpers willingly accept to patrol their route with me and search for any toads. "Should anyone can find any toads tonight, those two will spot one," says the group coordinator, indicating her 14-year-old son and the experienced member. After for two hours without a single toad sighting, and now they have climbed over a wire barrier to check under some wood.
Community Participation
The mother and son became part of the patrol a while back. The teenager adores all things wildlife and has an goal to become a environmentalist, so his mother started to look for activities they could do together to protect local wildlife. Now she loves it as much as he does, the middle-aged entrepreneur tells me – so when the group was looking for a new manager recently, she decided to step up.
The teenager, too, has been instrumental in the group. A clip he created, imploring the municipal authority to close a street through a nature reserve during breeding time, swung the decision the team's way. After a twelve months of campaigning, the authority agreed to an "restricted access" rule between 5pm and 5am from late winter through to April. The majority of motorists respected and avoided the route.
Additional Species and Difficulties
Several vehicles go by when I'm out on duty and we discover some casualties as a result – no amphibians, but several crushed salamanders. We see one living newt as well, and the youngster is particularly pleased to see a harvestman, which dances in his hands. Yet despite the team's hardest attempts to show me a toad, the native community has clearly gone dormant for the winter. It seems that I wouldn't have had any more luck elsewhere in the nation – all the patrol groups I contact explain that it's very difficult at this season.

A message I get from another volunteer, who has kindly made the effort to check for toads in a noted location, thought to be the largest accurately monitored toad population in the UK, reaches me with the subject line: "None found." However, in February and March, he tells me, the group plans to assist approximately 10,000 adult toads over the street.
Effectiveness and Challenges
How much of a difference can these groups actually make? "The reality that volunteers are performing this consistently on cold, damp and unpleasant evenings is quite extraordinary," says an expert. "That's something that very much deserves recognition." However, while toad patrols are able to reduce the drop, they can't stop it completely – partly since vehicles is just one danger.
Other Dangers
The climate crisis has resulted in extended spells of dry weather, which create the poor environment for some of the creatures that toads eat, such as invertebrates, while warmer ponds have led to an rise of toxic plants, which can be harmful to toads. Warmer cold seasons also cause toads to emerge from their hibernation more frequently, disrupting the resource preservation vital to their life cycle. Habitat destruction – particularly the disappearance of big water bodies – is another menace.
Experts are "often concerned about putting too much of a utilitarian spin on wildlife," but "There is a big value in just their presence." But toads play an significant part in the food chain, consuming pretty much any invertebrates or small animals they can swallow and in turn feeding a number of birds and mammals, such as hedgehogs and otters. Improving conditions for toads – such as creating more ponds, protecting forests and constructing toad tunnels – "benefits for a whole bunch of additional wildlife."
Historical Significance
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
