Can Britain's Toads Be Saved from Traffic and Terrible Decline?
It's a Friday evening at 7:30, but instead of going out or relaxing at home, I've caught a train to a market town in Wiltshire to meet up with local helpers from a toad patrol. These committed people give up their evenings to safeguard the local toad population.
An Alarming Drop in Numbers
The common toad is becoming increasingly uncommon. A recent study led by an wildlife conservation group showed that the British common toad numbers have almost halved since 1985. Seeing a creature that has been a fixture of the British countryside in decline is labeled "concerning" by experts. Toads "don't require very particular environments" and "should be able to live quite well in the majority of areas in the UK," meaning if even they are struggling to persist, "it kind of suggests that things are not as they should be."
Toad populations across the UK have declined by almost 50% since the 1980s
The Danger from Roads
Though the study didn't cover the causes for the drop, traffic is a major factor. Estimates indicate that 20 tonnes of toads are crushed on British roads annually – that is, hundreds of thousands. Unlike frogs, which would probably be happy 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 travel further 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.
Migration Patterns
Appropriately enough, the initial amphibians begin their quest for a mate around February 14th, but others travel as far as April, waiting until it gets dark and moving through the night. During that period, toads begin migrating from wherever they have been overwintering "all pretty much at the same time."
A local helper, who was raised in the area and has been trying to protect its amphibians since he was a boy, notes that "Their sole purpose: to go and have an orgy." If their path happens to a street, they could all get run over, and that breeding season would never happen – preventing a new generation of toads from being born.
Toad Patrols Throughout the United Kingdom
Finding hundreds of dead toads on nearby streets "resonates deeply with people," and has led to the creation of toad patrols across the UK – hundreds of organizations are officially listed with a national initiative. These groups collect toads and carry them across roads in buckets, as well as counting the number of toads they find and advocating for other protection measures, such as road closures and underground wildlife tunnels.
Volunteers usually work during the breeding period, when toad crossings are more regular. However, this means they can miss numbers of toadlets, which, having existed as spawn and then juveniles, leave their water habitats over an irregular timetable in late summer. Because of their small stature – just a couple of cm wide – "they are destroyed by car traffic." And as being run over "basically turns them into mush," it's harder to get data on them. At least when mature amphibians are killed, their remains can be tallied.
Annual Efforts
Unlike many groups, a specific volunteer group, who are in their eighth season of functioning, go out year-round – not every night, but whenever 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" – winter dormancy has begun and it's been a arid period – but several of the volunteers willingly accept to walk up and down their area with me and search for any toads. "If anyone can locate any toads tonight, those two will spot one," says the patrol manager, pointing to her 14-year-old son and the experienced member. We've been out for 120 minutes without a glimpse of any amphibians, and now they have climbed over a barbed wire fence to check under some logs.
Community Involvement
The family duo became part of the patrol a while back. The teenager adores all things wildlife and has an ambition to become a conservationist, so his mother started to search for things they could do together to help native animals. Now she loves it as much as he does, the 41-year-old small business owner explains – so when the group was seeking a new manager recently, she decided to step up.
The teenager, too, has played an important role in the organization. A video he made, urging the municipal authority to block a road through a protected area during migration season, swung the decision the group's way. After a twelve months of lobbying, the authority approved an "access-only" rule between evening and morning from February through to spring. The majority of motorists duly avoided the route.
Other Wildlife and Difficulties
A few vehicles go by when I'm out on duty and we find some victims as a consequence – no amphibians, but several crushed salamanders. We see one living newt as well, and the youngster is especially excited to see a harvestman, which moves in his hands. Yet despite the team's hardest attempts to show me a toad, the local population has clearly settled down for the colder months. It seems that I couldn't have found any more luck anywhere else in the nation – all the rescue teams I contact clarify that it's near-impossible at this time of year.
The group expects to help approximately 10,000 adult toads across the road
One email I receive from a different helper, who has generously taken the trouble to look for toads in a famous site, thought to be the largest accurately monitored toad group in the UK, arrives in my inbox with the subject line: "None found." However, in late winter, he informs me, the group plans to assist approximately 10,000 mature amphibians over the street.
Effectiveness and Challenges
How much of a difference can these groups actually make? "The reality that volunteers are performing this regularly on chilly, wet and miserable evenings is quite extraordinary," notes an researcher. "That's something that very much deserves recognition." However, while rescue teams are able to reduce the drop, they cannot prevent it entirely – partly since traffic is not the only threat.
Additional Threats
The global warming has resulted in extended spells of dry weather, which create the wrong conditions for some of the creatures that toads consume, such as worms and slugs, while warmer ponds have caused an rise of toxic plants, which can be harmful to toads. Milder winters also cause toads to wake up from their dormancy more often, interfering with the resource preservation vital to their life cycle. Habitat destruction – particularly the disappearance of big water bodies – is another menace.
Experts are "always a bit worried about putting too much of a utilitarian spin on wildlife," however "There is a big value in just having these animals around." But toads do have an important role in the ecosystem, eating almost any invertebrates or small animals they can swallow and in turn sustaining a variety of birds and mammals, such as wildlife. Improving conditions for toads – ie creating more ponds, conserving woodland and constructing amphibian passages – "we'll improve them for a whole bunch of additional wildlife."
Historical Significance
An additional motive to try to keep toads present is their "important cultural value," notes an specialist. Myths and folklore around toads date back {centuries|hundred
