Will the UK's Toads Be Saved from Roads and Terrible Decline?
It is Friday evening at half past seven, but rather than heading to the pub or watching a film, I've taken a train to a market town in Wiltshire to meet up with local helpers from a toad patrol. These dedicated individuals give up their evenings to protect the local toad population.
A Worrying Decline in Numbers
The Bufo bufo is becoming increasingly rare. A latest research conducted by an wildlife conservation group showed that the British common toad numbers have dropped by half since 1985. Observing a species that has been a stalwart of the British countryside in decrease is labeled "worrying" by researchers. Toads "don't require very specific conditions" and "should be able to live successfully in the majority of areas in the UK," so if even they are struggling to persist, "it indicates that the ecosystem is unbalanced."
Toad populations across the UK have declined by almost 50% since the 1980s
The Threat from Roads
Though the study didn't cover the reasons for the drop, traffic is a major factor. Estimates suggest that 20 tonnes of toads are crushed on British roads every year – in other words, hundreds of thousands. In contrast to frogs, which might be happy to mate "with just a bucket of water," toads prefer big bodies of water. Their ability to remain away from water for longer than frogs means they can travel further to find them – often long distances. They usually stick to their ancestral migration routes – it's common for mature amphibians to return to their natal pond to mate.
Migration Patterns
Fittingly, the initial amphibians begin their quest for a partner around Valentine's day, but some move as far as spring, waiting until it gets dark and moving through the night. During that time, toads start moving from where they have been hibernating "almost simultaneously."
A local helper, who grew up in the region and has been trying to protect its toad population since he was a boy, notes that "Their sole purpose: to go and mate." If their route happens to a street, they could be killed by traffic, and that breeding season would be lost – preventing a next generation of toads from being produced.
Toad Patrols Across the UK
Finding hundreds of dead toads on nearby streets "resonates deeply with people," and has resulted in the formation of rescue teams throughout the UK – hundreds of organizations are currently registered with a countrywide program. These groups pick up toads and carry them over streets in buckets, as well as recording the quantity of toads they find and lobbying for other protection measures, such as blocked roads and amphibian passages.
Volunteers tend to operate during the migration season, when toad crossings are more regular. However, this implies they can miss numbers of young toads, which, having existed as eggs and then juveniles, exit their water habitats over an irregular timetable in the end of summer. Because of their size – just a couple of cm wide – "they are destroyed by vehicles." And as being run over "basically turns them into mush," it's harder to collect information on them. At least when mature amphibians are killed, their remains can be counted.
Year-Round Efforts
Unlike most patrols, a specific volunteer group, who are in their eighth year of operating, go out year-round – not nightly, but whenever weather are damp, or if someone has posted about a toad sighting in their group chat. When I request to accompany them on patrol, they concede it is "not ideal conditions" – winter dormancy has begun and it's been a arid period – but several of the volunteers willingly accept to patrol their route with me and see what we can find. "If anyone can find any toads tonight, that pair will find one," says the patrol manager, pointing to her 14-year-old son and the longtime volunteer. After for 120 minutes without a glimpse of any amphibians, and now they have scaled a barbed wire fence to inspect beneath some logs.
Community Involvement
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 conservationist, so his mother started to look for things they could do together to protect local wildlife. Now she enjoys it as much as he does, the middle-aged small business owner tells me – so when the team was looking for a new manager lately, she decided to step up.
The youth, too, has played an important role in the group. A clip he created, urging the municipal authority to close a road through a nature reserve during migration season, swung the decision the team's way. After a twelve months of lobbying, the council agreed to an "access-only" restriction between evening and morning from late winter through to spring. The majority of motorists respected and avoided the road.
Additional Species and Difficulties
Several vehicles go by when I'm out on duty and we discover some victims as a result – no toads, but several crushed salamanders. We spot one live amphibian as well, and the youngster is particularly pleased to see a harvestman, which moves in his hands. Yet in spite of the team's hardest attempts to let me see a toad, the native community has clearly settled down for the colder months. It appears that I wouldn't have had any better success anywhere else in the country – all the patrol groups I reach out to clarify that it's very difficult at this time of year.
The group expects to help approximately 10,000 adult toads across the road
One email I get from a different helper, who has kindly made the effort to look for toads in a famous site, considered the biggest tracked toad group in the UK, reaches me with the title: "No toads." However, in late winter, he tells me, the team plans to assist around ten thousand adult toads over the street.
Effectiveness and Challenges
How much of a difference can these groups truly achieve? "The fact that volunteers are doing this consistently on cold, damp and unpleasant evenings is remarkable," notes an researcher. "This effort that very much deserves recognition." However, while toad patrols are able to reduce the drop, they cannot prevent it entirely – partly since traffic is not the only threat.
Additional Threats
The climate crisis has resulted in extended spells of dry weather, which cause the poor environment for some of the animals that toads consume, such as invertebrates, while warmer ponds have caused an increase of blue-green algae, which can be toxic to toads. Milder winters also lead toads to wake up from their dormancy more frequently, disrupting the energy conservation crucial to their existence. Loss of environment – particularly the disappearance of large ponds – is another menace.
Researchers are "always a bit worried about putting too much of a utilitarian spin on wildlife," but "There is a big value in just having these animals around." But toads play an significant part in the food chain, eating pretty much any small creatures or small animals they can fit in their mouths and in turn sustaining a number of predators, such as hedgehogs and otters. Enhancing conditions for toads – such as creating more ponds, protecting forests and constructing toad tunnels – "we'll improve them for a wide range of additional wildlife."
Historical Significance
Another reason to try to keep toads around is their "important cultural value," notes an expert. Legends and tales around toads date back {centuries|hundred
