Can the UK's Toads Be Saved from Roads and Population Collapse?
It is Friday night at 7:30, but instead of going out or relaxing at home, I've caught 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.
A Worrying Decline in Numbers
The Bufo bufo is becoming increasingly rare. A recent study led by an amphibian and reptile charity revealed that the UK toad population have almost halved since 1985. Observing a species that has been a fixture of the British countryside in decrease is labeled "worrying" by experts. Toads "don't need very particular environments" and "ought to live quite well in most of habitats in Britain," so if even they are struggling to persist, "it indicates that things are not as they should be."

The Danger from Traffic
Though the study didn't examine the reasons for the decline, traffic certainly plays a part. Calculations suggest that 20 tonnes of toads are crushed on UK roads every year β in other words, several hundred thousand. In contrast to frogs, which might be happy to mate "if you left out a bucket of water," toads prefer big bodies of water. Their ability to remain away from water for longer than frogs allows they can journey farther to reach them β sometimes hundreds of metres. They tend to follow their traditional paths β it's common for mature amphibians to go back to their natal pond to mate.
Breeding Patterns
Appropriately enough, the initial amphibians start their journey for a partner around Valentine's day, but others travel as late as April, waiting until it gets night and travelling after sunset. During that time, toads begin migrating from where they have been hibernating "all pretty much at the same time."
One volunteer, who was raised in the area and has been trying to protect its toad population since he was a boy, explains that "Their sole purpose: to go and have an orgy." If their path crosses a road, they could be killed by traffic, and that mating period would be lost β preventing a next generation of toads from being born.
Rescue Groups Throughout the UK
Finding hundreds of toad carcasses on nearby streets "resonates deeply with people," and has resulted in the creation of rescue teams across the UK β 274 groups are officially listed with a national initiative. These teams pick up toads and carry them across roads in buckets, as well as counting the number of toads they find and advocating for other safety solutions, such as road closures and underground wildlife tunnels.
Volunteers usually work during the migration season, when toad crossings are more regular. However, this implies they can miss groups of toadlets, which, having been eggs and then tadpoles, exit their ponds over an irregular timetable in late summer. Because of their small stature β just one or two centimetres wide β "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 lost, their remains can be tallied.
Annual Work
Unlike most patrols, a specific volunteer group, who are in their eighth season of operating, go out throughout the year β not every night, but when weather are damp, or if someone has reported about a amphibian spotting in their group chat. When I ask to join them on patrol, they concede it is "not a toady night" β winter dormancy has started and it's been a dry day β but several of the volunteers gamely agree to patrol their area with me and see what we can find. "If anyone can locate any toads tonight, that pair will spot one," says the patrol manager, pointing to her teenage child and the longtime volunteer. After for 120 minutes without a glimpse of any amphibians, and now they have climbed over a wire barrier to inspect beneath some logs.
Community Participation
The family duo joined the group 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 look for activities they could do jointly to protect local wildlife. Now she loves it as much as he does, the 41-year-old entrepreneur explains β so when the team was looking for a new manager lately, she volunteered for the role.
The teenager, too, has been instrumental in the organization. A clip he created, urging the local council to close a street through a nature reserve during migration season, influenced the outcome the group's way. After a year of campaigning, the council agreed to an "access-only" rule between evening and morning from February through to April. The majority of motorists respected and avoided the route.
Other Wildlife and Challenges
A few vehicles go past when I'm out on duty and we find some victims as a result β no amphibians, but three squashed newts. We see one live amphibian 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 obviously gone dormant for the colder months. It seems that I wouldn't have had any better success anywhere else in the country β all the patrol groups I contact explain that it's near-impossible at this time of year.
The group expects to help approximately 10,000 adult toads across the road
A message I receive from another volunteer, who has kindly made the effort to check for toads in a noted location, considered the largest accurately monitored toad group in the UK, reaches me with the title: "None found." However, in February and March, he tells me, the team expects to help approximately ten thousand mature amphibians over the street.
Effectiveness and Challenges
What level of impact can these organizations actually make? "The reality that people are performing this regularly on chilly, wet and miserable evenings is remarkable," says an expert. "This effort that very much should be celebrated." However, while toad patrols are able to reduce the drop, they cannot prevent it entirely β partly since vehicles is just one danger.
Additional Threats
The climate crisis has resulted in extended spells of dry weather, which create the poor environment for some of the animals that toads consume, such as worms and slugs, while higher water temperatures have caused an increase of toxic plants, which can be toxic to toads. Milder winters also lead toads to emerge from their dormancy more often, interfering with the energy conservation vital to their existence. Habitat destruction β particularly the loss of large ponds β is an additional threat.
Researchers are "often concerned about overemphasizing practical benefits on biodiversity," however "There is a big value in just having these animals around." But toads do have an significant part in the food chain, consuming almost any small creatures or tiny organisms they can swallow and in turn feeding a number of predators, such as wildlife. Enhancing conditions for toads β such as building water habitats, protecting forests and installing toad tunnels β "we'll improve them for a wide range of other species."
Historical Importance
Another reason to try to keep toads around is their "historical significance," notes an specialist. Legends and tales around toads go back {centuries|hundred
