Can the UK's Toads Survive from Traffic and Terrible Decline?
It is Friday night at half past seven, but rather than going out or relaxing at home, I've caught a train to a town in Wiltshire to join volunteers from a toad patrol. These dedicated individuals sacrifice their evenings to protect the local toad population.
An Alarming Decline in Numbers
The Bufo bufo is growing more uncommon. A latest research conducted by an amphibian and reptile charity revealed that the UK toad population have dropped by half since the mid-1980s. Seeing a species that has been a fixture of the British countryside in decline is labeled "worrying" by experts. Toads "don't require very particular environments" and "ought to live quite well in most of areas in the UK," meaning if even they are not managing to survive, "it kind of suggests that things are not as they should be."

The Threat from Roads
Though the study didn't examine the causes for the decline, traffic is a major factor. Calculations suggest that 20 tons of toads are killed on UK roads every year – in other words, several hundred thousand. In contrast to frogs, which would probably be content to mate "with just a small container," toads favor large ponds. Their capacity to remain away from water for more time than frogs means they can journey farther to find them – sometimes long distances. They usually follow their traditional paths – it's typical for mature amphibians to go back to their birth pond to mate.
Breeding Habits
Fittingly, the first toads start their journey for a partner around February 14th, but others travel as far as April, waiting until it gets dark and moving through the night. During that period, toads start moving from wherever they have been hibernating "all pretty much at the same time."
A local helper, who grew up in the region and has been working to save its toad population since he was a child, explains that "They've got just one focus: to go and mate." If their path happens to a road, they could all get run over, and that breeding season would never happen – preventing a next generation of toads from being born.
Toad Patrols Across the UK
Seeing hundreds of dead toads on local roads "inherently strikes a chord with people," and has resulted in the formation of toad patrols throughout the UK – 274 groups are officially listed with a countrywide program. These groups collect toads and carry them over streets in buckets, as well as counting the number of toads they find and lobbying for other protection measures, such as blocked roads and amphibian passages.
Volunteers usually work during the migration season, when amphibian movements are more regular. However, this implies they can miss groups of toadlets, which, having existed as eggs and then juveniles, leave their ponds over an irregular timetable in the end of summer. Because of their size – just a couple of cm wide – "they are destroyed by car traffic." And as being run over "essentially crushes them," it's more difficult to collect information on them. At least when adult toads are killed, their remains can be tallied.
Annual Efforts
In contrast to most patrols, one local team, who are in their eighth year of functioning, go out throughout the year – not every night, but whenever weather are damp, or if a member has reported about a toad sighting in their group chat. When I request to accompany them on patrol, they concede it is "not a toady night" – toad hibernation season has started and it's been a arid period – but several of the volunteers willingly accept to patrol their route with me and search for any toads. "If anyone can find any toads tonight, that pair will spot one," says the group coordinator, pointing to her 14-year-old son and the longtime volunteer. After for two hours without a single toad sighting, and now they have scaled a barbed wire fence to check under some wood.
Family Involvement
The mother and son became part of the group a year and a half ago. The youngster loves all things wildlife and has an goal 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 entrepreneur explains – so when the group was looking for a new manager lately, she decided to step up.
The youth, too, has played an important role in the organization. A clip he created, urging the municipal authority to block a street through a protected area during breeding time, swung the decision the group's way. After a year of campaigning, the authority agreed to an "restricted access" restriction between evening and morning from late winter through to April. Most drivers respected and avoided the road.
Other Wildlife and Difficulties
A few cars go by when I'm out on patrol and we discover some victims as a consequence – no toads, but several crushed salamanders. We see one live amphibian as well, and the youngster is especially excited to see a harvestman, which dances in his palms. Yet in spite of the team's best efforts to show me a toad, the native community has obviously gone dormant for the colder months. It appears that I wouldn't have had any better success elsewhere in the country – all the patrol groups I contact explain that it's very difficult at this time of year.

A message I get from another volunteer, who has generously taken the trouble to look 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 informs me, the team plans to assist around ten thousand adult toads across the road.
Impact and Limitations
How much of a difference can these organizations actually make? "The reality that volunteers are performing this regularly on chilly, wet and miserable evenings is quite extraordinary," says an researcher. "This effort that very much should be celebrated." However, while toad patrols are able to reduce the drop, they can't stop it completely – partly since traffic is just one danger.
Other Dangers
The global warming has meant 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 rise of blue-green algae, which can be toxic to toads. Warmer cold seasons also lead toads to emerge from their dormancy more often, disrupting the energy conservation crucial to their existence. Loss of environment – especially the loss of big water bodies – is another menace.
Experts are "always a bit worried about overemphasizing practical benefits on biodiversity," but "There is a big value in just their presence." But toads play an significant part in the ecosystem, consuming almost any small creatures or tiny organisms they can fit in their mouths and in turn feeding a variety of birds and mammals, such as wildlife. Improving situations for toads – ie building water habitats, protecting forests and installing amphibian passages – "we'll improve them for a whole bunch of additional wildlife."
Historical Importance
Another reason to work to preserve toads around is their "historical significance," adds an expert. Legends and tales around toads go back {centuries|hundred
