Will Britain's Common Toads Survive from Roads and Population Collapse?

It's a Friday evening at 7:30, but rather than heading to the pub or relaxing at home, I've taken a train to a market town in Wiltshire to meet up with local helpers from a toad patrol. These committed people sacrifice their evenings to protect the native amphibian community.

A Worrying Drop in Population

The common toad is growing more rare. A recent research led by an wildlife conservation group revealed that the British common toad numbers have almost halved since the mid-1980s. Seeing a species that has been a fixture of the British countryside in decrease is described as "concerning" by researchers. Toads "don't require very particular environments" and "ought to live successfully in the majority of habitats in Britain," so if even they are struggling to persist, "it kind of suggests that things are not as they should be."

The Threat from Roads

Though the research didn't examine the causes for the drop, traffic is a major factor. Estimates indicate that 20 tonnes of toads are killed on UK roads annually – that is, hundreds of thousands. In contrast to frogs, which might be content to mate "if you left out a bucket of water," toads favor large ponds. Their ability to stay out of water for more time than frogs means they can travel further to find them – often long distances. They tend to stick to their traditional paths – it's common for mature amphibians to return to their birth pond to mate.

Migration Patterns

Appropriately enough, the initial amphibians start their journey for a partner around February 14th, but others travel as late as spring, until it gets dark and moving after sunset. During that time, toads start moving from wherever they have been overwintering "almost simultaneously."

A local helper, who was raised in the area and has been working to save its amphibians since he was a boy, explains that "Their sole purpose: to go and mate." If their path crosses a street, they could all get run over, and that mating period would never happen – stopping a next generation of toads from being born.

Rescue Groups Across the United Kingdom

Seeing many of toad carcasses on nearby streets "inherently strikes a chord with people," and has resulted in the formation of rescue teams across the UK – hundreds of organizations are officially listed with a countrywide program. These teams collect toads and carry them across roads in containers, as well as counting the number of toads they encounter and lobbying for other safety solutions, such as blocked roads and underground wildlife tunnels.

Volunteers tend to operate during the migration season, when toad crossings are more regular. However, this implies they can miss numbers of toadlets, which, having existed as spawn 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 hit "basically turns them into mush," it's harder to get data on them. At least when mature amphibians are killed, their carcasses can be counted.

Year-Round Efforts

Unlike many groups, one local team, who are in their eighth year of functioning, go out throughout the year – not every night, but when conditions are damp, or if someone has posted about a toad sighting in their group chat. When I request to accompany them on duty, they admit it is "not a toady night" – toad hibernation season has begun and it's been a arid period – but a few of the helpers willingly accept to patrol their area with me and search for any toads. "Should anyone can locate any toads tonight, that pair will find one," says the group coordinator, indicating 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 wire barrier to inspect beneath some logs.

Community Participation

The family duo became part of the group a year and a half ago. The teenager loves all things nature-related and has an goal to become a conservationist, so his mother started to look for activities they could do jointly to help native animals. Now she loves it as much as he does, the 41-year-old entrepreneur explains – so when the group was looking for a new manager recently, she volunteered for the role.

The teenager, too, has played an important role in the group. A clip he created, urging the local council to block a road through a nature reserve during breeding time, swung the decision the team's way. After a twelve months of campaigning, the authority approved 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

Several cars go by when I'm out on duty and we find some casualties as a consequence – no amphibians, but several crushed salamanders. We spot one live amphibian as well, and the teenager is especially excited to see a daddy longlegs, which dances in his palms. Yet in spite of the team's best efforts to let me see a toad, the native community has obviously gone dormant for the colder months. It appears that I wouldn't have had any better success anywhere else in the nation – all the patrol groups I reach out to explain that it's very difficult at this season.

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 population in the UK, arrives in my inbox with the title: "None found." However, in late winter, he tells me, the group plans to assist around ten thousand mature amphibians across the road.

Effectiveness and Challenges

How much of a difference can these groups actually make? "The fact that people are doing this consistently on cold, damp and unpleasant evenings is remarkable," says an researcher. "That's something that very much deserves recognition." However, while toad patrols are able to slow the decline, they can't stop it completely – partly since traffic is just one danger.

Other Dangers

The climate crisis has meant longer periods of dry weather, which cause the poor environment for some of the animals that toads consume, such as invertebrates, while higher water temperatures have led to an rise of toxic plants, which can be toxic to toads. Warmer cold seasons also cause toads to emerge from their hibernation more frequently, interfering with the resource preservation crucial to their existence. Loss of environment – especially the loss of big water bodies – is an additional threat.

Experts are "often concerned about overemphasizing practical benefits on biodiversity," however "It's important in just having these animals around." But toads do have an important role in the ecosystem, consuming almost any small creatures or small animals they can swallow and in turn feeding a variety of birds and mammals, such as hedgehogs and otters. Improving situations for toads – ie creating more ponds, conserving woodland and installing amphibian passages – "benefits for a wide range of other species."

Historical Importance

An additional motive to work to preserve toads around is their "historical significance," notes an expert. Myths and folklore around toads date back {centuries|hundred
