Can the UK's Common Toads Survive from Roads and Terrible Decline?

It is a Friday evening at 7:30, but instead of going out or watching a film, I've taken a train to a market town in the countryside to join local helpers from a amphibian rescue group. These dedicated individuals sacrifice their evenings to safeguard the local toad population.

A Worrying Decline in Numbers

The common toad is growing more uncommon. A latest study conducted by an amphibian and reptile charity revealed that the British common toad numbers have almost halved since 1985. Seeing a species that has been a fixture of the UK landscape in decline is labeled "worrying" by experts. Toads "don't need very particular environments" and "ought to live quite well in the majority of habitats in the UK," so if even they are struggling to persist, "it kind of suggests that the ecosystem is unbalanced."

The Threat from Roads

Though the research didn't cover the causes for the decline, traffic certainly plays a part. Calculations indicate that 20 tons of toads are crushed on British roads annually – that is, hundreds of thousands. Unlike frogs, which might be content to mate "if you left out a small container," toads favor big bodies of water. Their capacity to stay out of water for longer than frogs means 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 birth pond to mate.

Breeding Patterns

Fittingly, the first toads start their journey for a mate around Valentine's day, but some move as late as April, until it gets night and moving after sunset. During that time, toads begin migrating from where they have been overwintering "almost simultaneously."

A local helper, who was raised in the region and has been trying to protect its amphibians since he was a boy, explains that "They've got just one focus: to go and mate." If their path happens to a street, they could be killed by traffic, and that mating period would never happen – stopping a new generation of toads from being born.

Rescue Groups Throughout the United Kingdom

Finding hundreds of dead toads on local roads "inherently strikes a chord with people," and has resulted in the creation of toad patrols across the UK – hundreds of organizations are currently registered with a national initiative. These teams collect toads and transport them across roads in buckets, as well as recording the quantity of toads they find and advocating for other safety solutions, such as blocked roads and amphibian passages.

Volunteers tend to operate during the migration season, when amphibian movements are frequent. However, this means they can miss groups of toadlets, which, having existed as spawn and then juveniles, leave their water habitats over an unpredictable schedule in late summer. Because of their size – just one or two centimetres wide – "they can get obliterated by car traffic." And as being hit "essentially crushes them," it's more difficult to collect information on them. At least when adult toads are lost, their remains can be counted.

Annual Efforts

In contrast to many groups, one local team, who are in their eighth year of operating, go out year-round – not nightly, but whenever conditions are damp, or if someone has reported about a amphibian spotting in their messaging app. When I request to accompany them on duty, they concede it is "not a toady night" – winter dormancy has begun and it's been a dry day – but a few of the helpers gamely agree to walk up and down their route with me and see what we can find. "If anyone can find any toads tonight, those two will spot one," says the patrol manager, indicating her 14-year-old son and the experienced member. After for two hours without a glimpse of any amphibians, and now they have scaled a barbed wire fence to inspect beneath some wood.

Community Involvement

The family duo joined the group a year and a half ago. The youngster adores all things nature-related and has an ambition to become a environmentalist, so his parent started to search for things they could do together to help native animals. Now she loves it as much as he does, the middle-aged entrepreneur explains – so when the team was seeking a fresh coordinator recently, she volunteered for the role.

The youth, too, has played an important role in the organization. A video he made, urging the local council to close a road through a protected area during breeding time, influenced the outcome the team's way. After a year of campaigning, the council agreed to an "restricted access" restriction between 5pm and 5am from late winter through to April. The majority of motorists respected and avoided the road.

Additional Species and Challenges

A few vehicles go past when I'm out on duty and we discover some casualties as a consequence – no amphibians, but three squashed newts. We spot one living newt as well, and the youngster is especially excited to see a daddy longlegs, which dances in his hands. Yet despite the team's best efforts to let me see a toad, the native community has obviously settled down for the winter. It seems that I couldn't have found any better success anywhere else in the country – all the patrol groups I contact explain that it's very difficult at this season.

They project rescuing nearly 10,000 grown amphibians during migration

One email I receive from another volunteer, who has generously made the effort to check for toads in a noted location, considered the biggest tracked toad population in the UK, arrives in my inbox with the title: "No toads." However, in late winter, he informs me, the team plans to assist approximately 10,000 mature amphibians over the street.

Impact and Challenges

What level of impact can these groups actually make? "The reality that volunteers are doing this consistently on chilly, wet and miserable late nights is quite extraordinary," says an expert. "This effort that very much should be celebrated." However, while toad patrols are able to slow the decline, they cannot prevent it entirely – not least because traffic is just one danger.

Additional Threats

The global warming has resulted in longer periods of drought, which create the poor environment for some of the creatures that toads eat, such as worms and slugs, while higher water temperatures have led to an increase of blue-green algae, which can be harmful to toads. Warmer cold seasons also lead toads to emerge from their hibernation more often, interfering with the resource preservation crucial to their life cycle. Loss of environment – especially the loss of large ponds – is an additional threat.

Researchers are "always a bit worried about overemphasizing practical benefits on wildlife," however "It's important in just having these animals around." But toads do have an significant part in the ecosystem, eating pretty much any invertebrates or small animals they can swallow and in turn sustaining a variety of birds and mammals, such as wildlife. Enhancing conditions for toads – such as creating more ponds, protecting forests and constructing amphibian passages – "we'll improve them for a wide range of other species."

Historical Significance

Another reason to try to keep toads around is their "historical significance," adds an specialist. Legends and tales around toads date back {centuries|hundred
