Will the UK's Toads Survive from Traffic and Terrible Decline?
It's a Friday night at half past seven, but rather than going out or relaxing at home, I've taken a train to a town in the countryside to join local helpers from a toad patrol. These dedicated individuals sacrifice their evenings to safeguard the native amphibian community.
An Alarming Decline in Numbers
The Bufo bufo is growing more rare. A latest research led by an wildlife conservation group revealed that the British common toad numbers have almost halved since 1985. Observing a creature that has been a fixture of the British countryside in decline is described as "concerning" by researchers. Toads "don't require very particular environments" and "ought to live quite well in the majority of habitats in the UK," meaning if even they are struggling to persist, "it kind of suggests that the ecosystem is unbalanced."

The Danger from Traffic
Though the research didn't cover the causes for the decline, cars certainly plays a part. Calculations suggest that 20 tonnes of toads are crushed on UK roads annually – that is, hundreds of thousands. In contrast to frogs, which would probably be happy to mate "with just a small container," toads favor large ponds. Their capacity to remain away from water for more time than frogs allows they can journey farther to find them – often long distances. They usually follow their traditional paths – it's common for mature amphibians to go back to their birth pond to mate.
Breeding Habits
Fittingly, the initial amphibians start their journey for a partner around Valentine's day, but some move as late as spring, waiting until it gets dark and travelling 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 amphibians since he was a boy, explains that "Their sole purpose: to go and have an orgy." If their path happens to a road, they could be killed by traffic, and that mating period would be lost – preventing a next generation of toads from being produced.
Toad Patrols Throughout the United Kingdom
Finding many of dead toads on nearby streets "resonates deeply with people," and has led to the formation of toad patrols throughout the UK – hundreds of organizations are officially listed with a national initiative. These groups pick up toads and carry them across roads in buckets, as well as recording the number of toads they encounter and lobbying for other protection measures, such as road closures and underground wildlife tunnels.
Patrols tend to operate during the migration season, when amphibian movements are more regular. However, this implies they can overlook groups of young toads, which, having been spawn and then tadpoles, exit their water habitats over an unpredictable schedule in late summer. Because of their small stature – just a couple of cm wide – "they are destroyed by vehicles." And as being run over "basically turns them into mush," it's more difficult to get data on them. At least when adult toads are lost, their remains can be tallied.
Year-Round Work
Unlike many groups, one local team, who are in their eighth season of functioning, go out throughout the year – not every night, but when weather are damp, or if a member has posted about a toad sighting in their messaging app. 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 volunteers gamely agree to walk up and down their area with me and search for any toads. "Should anyone can find any toads tonight, that pair will spot one," says the group coordinator, pointing to her teenage child and the longtime volunteer. After for 120 minutes without a single toad sighting, and now they have climbed over a barbed wire fence to check under some wood.
Community Involvement
The mother and son joined the group a while back. The youngster loves all things nature-related and has an goal to become a conservationist, so his parent started to search for things they could do together to help local wildlife. Now she loves it as much as he does, the middle-aged small business owner tells me – so when the group was seeking a new manager recently, she volunteered for the role.
The teenager, too, has been instrumental in the organization. A clip he made, urging the municipal authority to close a road through a protected area during breeding time, influenced the outcome the group's way. After a year of lobbying, 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
Several cars go past when I'm out on duty and we find some casualties as a consequence – no toads, but several crushed salamanders. We see one living newt as well, and the youngster is particularly pleased to see a harvestman, which moves in his palms. Yet in spite of the team's hardest attempts to let me see a toad, the local population has clearly settled down for the winter. It seems that I couldn't have found any more luck elsewhere in the country – all the rescue teams I contact clarify that it's very difficult at this time of year.
This team anticipates assisting around ten thousand mature toads over the street
One email I get from another volunteer, who has kindly taken the trouble to check for toads in a famous site, thought to be the biggest tracked toad group in the UK, reaches me with the title: "No toads." However, in February and March, he informs me, the group expects to help around ten thousand adult toads over the street.
Effectiveness and Limitations
How much of a difference can these organizations truly achieve? "The reality that volunteers are performing this consistently on cold, damp and unpleasant late nights is remarkable," notes an researcher. "That's something that very much should be celebrated." However, while rescue teams are able to reduce the drop, they can't stop it completely – not least because vehicles is not the only threat.
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 worms and slugs, while higher water temperatures have caused an increase of toxic plants, which can be harmful to toads. Milder winters also lead toads to wake up from their dormancy more frequently, interfering with the resource preservation vital to their life cycle. Loss of environment – particularly the disappearance of big water bodies – is another menace.
Researchers are "always a bit worried about overemphasizing practical benefits on biodiversity," however "It's important in just their presence." But toads play an important role in the ecosystem, consuming almost any small creatures or small animals they can fit in their mouths and in turn feeding a number of birds and mammals, such as hedgehogs and otters. Improving situations for toads – ie creating more ponds, conserving woodland and constructing amphibian passages – "benefits for a wide range of other species."
Cultural Importance
An additional motive to try to keep toads present is their "important cultural value," adds an specialist. Myths and folklore around toads date back {centuries|hundred
