Will the UK's Toads Survive from Traffic and Terrible Decline?
It is Friday night at 7:30, but instead of heading to the pub or relaxing at home, I've caught a train to a town in the countryside to meet up with volunteers from a amphibian rescue group. These committed people sacrifice their evenings to protect the native amphibian community.
An Alarming Decline in Numbers
The common toad is growing more uncommon. A recent research conducted by an wildlife conservation group revealed that the UK toad population have dropped by half since the mid-1980s. Observing a creature that has been a fixture of the UK landscape in decline is labeled "worrying" by experts. Toads "don't require very specific conditions" and "ought to live successfully in the majority of areas in Britain," so if even they are struggling to persist, "it indicates that the ecosystem is unbalanced."

The Threat from Traffic
Though the research didn't examine the causes for the drop, cars is a major factor. Estimates suggest that 20 tonnes of toads are killed on UK roads annually – that is, hundreds of thousands. In contrast to frogs, which would probably be happy to mate "if you left out a small container," toads prefer large ponds. Their capacity to remain away from water for more time than frogs allows they can journey farther to find them – sometimes long distances. They tend to follow their traditional paths – it's typical for mature amphibians to go back to their natal pond to mate.
Migration Patterns
Appropriately enough, the first toads begin their quest for a partner around February 14th, but others travel as late as spring, until it gets night and moving through the night. During that time, toads begin migrating from wherever they have been overwintering "almost simultaneously."
One volunteer, who grew up in the region and has been working to save its toad population since he was a boy, notes that "They've got just one focus: to go and mate." If their route happens to a street, they could be killed by traffic, and that mating period would never happen – stopping a new generation of toads from being born.
Toad Patrols Across the UK
Finding many of toad carcasses on nearby streets "inherently strikes a chord with people," and has led to the formation of toad patrols across the UK – hundreds of organizations are officially listed with a national initiative. These teams collect toads and carry them over streets in buckets, as well as recording the number of toads they find and advocating for other protection measures, such as blocked roads and amphibian passages.
Volunteers usually work during the migration season, when toad crossings are frequent. However, this implies they can overlook numbers of toadlets, which, having existed as spawn and then tadpoles, leave their water habitats over an irregular timetable in the end of summer. Because of their small stature – just one or two centimetres wide – "they can get obliterated by car traffic." And as being hit "essentially crushes them," it's harder to get data on them. At least when mature amphibians are killed, their carcasses can be counted.
Annual Work
In contrast to most patrols, one local team, who are in their eighth season of functioning, go out year-round – not nightly, but whenever conditions are damp, or if a member has posted about a amphibian spotting in their group chat. When I ask to join them on duty, they admit it is "not a toady night" – toad hibernation season has begun and it's been a dry day – but several of the helpers gamely agree to walk up and down their area 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. We've been out for 120 minutes without a single toad sighting, and now they have scaled a wire barrier to inspect beneath some wood.
Community Involvement
The mother and son became part of the patrol a year and a half ago. The teenager loves all things nature-related and has an ambition to become a environmentalist, so his parent started to look for activities they could do together to protect native animals. Now she enjoys it as much as he does, the middle-aged entrepreneur tells me – so when the team was looking for a fresh coordinator recently, she decided to step up.
The teenager, too, has played an important role in the group. A video he made, urging the local council to close a road through a protected area during breeding time, influenced the outcome the group's way. After a twelve months of campaigning, the council approved an "restricted access" restriction between 5pm and 5am from late winter through to spring. Most drivers respected and avoided the route.
Additional Species and Challenges
Several vehicles go by when I'm out on patrol and we find some casualties as a consequence – no amphibians, but several crushed salamanders. We spot one live amphibian as well, and the youngster is particularly pleased to see a daddy longlegs, which moves in his hands. Yet despite the team's hardest attempts to show me a toad, the local population has clearly gone dormant for the winter. It appears that I wouldn't have had any more luck elsewhere in the country – all the rescue teams I contact explain that it's very difficult at this time of year.

One email I get from another volunteer, who has kindly taken the trouble to look for toads in a famous site, considered the largest accurately monitored toad population in the UK, arrives in my inbox with the title: "No toads." However, in February and March, he informs me, the group plans to assist around ten thousand adult toads across the road.
Effectiveness and Limitations
What level of impact can these organizations truly achieve? "The reality that volunteers are doing this regularly on chilly, wet and miserable evenings is quite extraordinary," says an researcher. "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 longer periods of drought, which cause the wrong conditions for some of the creatures that toads consume, such as worms and slugs, while higher water temperatures have led to an increase of blue-green algae, which can be harmful to toads. Milder winters also cause toads to wake up from their hibernation more often, interfering with the energy conservation crucial to their life cycle. Loss of environment – particularly the loss of large ponds – is another menace.
Experts are "always a bit worried about putting too much of a utilitarian spin on wildlife," but "It's important in just their presence." But toads do have an significant part in the food chain, eating almost any small creatures or small animals they can swallow and in turn sustaining a variety of birds and mammals, such as hedgehogs and otters. Improving conditions for toads – such as creating more ponds, conserving woodland and installing amphibian passages – "we'll improve them for a wide range of additional wildlife."
Historical Importance
Another reason to try to keep toads present is their "historical significance," adds an expert. Myths and folklore around toads go back {centuries|hundred
