Can the UK's Toads Survive from Roads and Population Collapse?

It's Friday night at half past seven, but instead of going out or relaxing at home, I've taken a train to a market town in Wiltshire to meet up with volunteers from a toad patrol. These dedicated individuals sacrifice their evenings to protect the local toad population.

A Worrying Drop in Numbers

The Bufo bufo is becoming increasingly uncommon. A latest research conducted by an amphibian and reptile charity showed that the British common toad numbers have almost halved since the mid-1980s. Observing a creature that has been a fixture of the UK landscape in decrease is labeled "worrying" by experts. Toads "don't need very specific conditions" and "should be able to live quite well in most of areas in Britain," meaning if even they are not managing to survive, "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 examine the reasons for the drop, cars certainly plays a part. Estimates suggest that 20 tonnes of toads are crushed on British roads every year – that is, several hundred thousand. In contrast to frogs, which might be content to mate "with just a bucket of water," toads prefer big bodies of water. Their ability to stay out of water for more time than frogs allows they can travel further to find them – sometimes hundreds of metres. They tend to follow their ancestral migration routes – it's common for mature amphibians to go back to their natal pond to mate.

Breeding Patterns

Fittingly, the first toads start their journey for a mate around Valentine's day, but others travel as far as spring, until it gets night and travelling through the night. During that period, toads begin migrating from where they have been overwintering "almost simultaneously."

A local helper, who was raised in the area and has been trying to protect its toad population since he was a child, explains that "Their sole purpose: to go and mate." If their path happens to a road, they could all get run over, and that breeding season would never happen – stopping a next generation of toads from being born.

Toad Patrols Across the UK

Seeing many of dead toads on local roads "resonates deeply with people," and has led to the formation of rescue teams across the UK – hundreds of organizations are currently registered with a national initiative. These teams 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 road closures and amphibian passages.

Volunteers usually work during the breeding period, when amphibian movements are frequent. However, this implies they can miss numbers of young toads, which, having existed as eggs and then tadpoles, exit their water habitats over an irregular timetable in the end of summer. Because of their size – just one or two centimetres 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 carcasses can be tallied.

Year-Round Efforts

Unlike many groups, a specific volunteer group, who are in their eighth season of operating, go out year-round – not every night, but when conditions are warm and wet, or if someone has posted about a amphibian spotting in their messaging app. 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 helpers gamely agree to patrol their area with me and see what we can find. "If anyone can find any toads tonight, those two will spot 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 check under some wood.

Family Involvement

The mother and son became part of the patrol a while back. The youngster adores all things wildlife and has an goal to become a environmentalist, so his parent started to look for activities they could do together to help local wildlife. Now she enjoys it as much as he does, the middle-aged small business owner tells me – so when the group was looking for a fresh coordinator lately, she decided to step up.

The youth, too, has been instrumental in the group. A clip he created, imploring the municipal authority to close a street through a protected area during breeding time, influenced the outcome the team's way. After a twelve months of campaigning, the council agreed to an "access-only" 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 amphibians, but several crushed salamanders. We spot one living newt as well, and the teenager is especially excited to see a harvestman, which moves in his palms. Yet despite the team's best efforts to show me a toad, the local population has obviously gone dormant for the winter. It seems that I wouldn't have had any better success elsewhere in the nation – all the rescue teams I reach out to explain that it's near-impossible at this time of year.

This team anticipates assisting around ten thousand mature toads over the street

A message I get from another volunteer, who has kindly taken the trouble to check for toads in a famous site, considered the largest accurately monitored toad group in the UK, reaches me with the title: "No toads." However, in February and March, he informs me, the team plans to assist around ten thousand mature amphibians across the road.

Impact and Challenges

How much of a difference can these organizations truly achieve? "The reality that volunteers are performing this consistently on chilly, wet and miserable late nights is quite extraordinary," says an expert. "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 traffic is just one danger.

Additional Threats

The climate crisis has meant longer periods of dry weather, which cause the poor environment for some of the creatures that toads eat, such as invertebrates, while higher water temperatures have led to an rise 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 resource preservation crucial to their life cycle. Habitat destruction – particularly the loss of big water bodies – is an additional threat.

Experts are "often concerned about putting too much of a utilitarian spin on biodiversity," but "It's important in just their presence." But toads play an important role in the food chain, consuming pretty much any invertebrates or small animals they can swallow and in turn feeding a variety of birds and mammals, such as wildlife. Enhancing situations for toads – such as creating more ponds, conserving woodland and installing toad tunnels – "we'll improve them for a wide range of additional wildlife."

Historical Significance

Another reason to work to preserve toads around is their "important cultural value," notes an specialist. Legends and tales around toads go back {centuries|hundred
