Can Britain's Common Toads Survive from Traffic and Population Collapse?

It is Friday night at half past seven, but instead of going out or watching a film, I've taken a train to a town in the countryside to meet up with volunteers from a toad patrol. These committed people sacrifice their evenings to protect the native amphibian community.

A Worrying Drop in Numbers

The common toad is becoming increasingly uncommon. A recent study led by an amphibian and reptile charity revealed that the UK toad population have dropped by half since the mid-1980s. Observing a creature that has been a fixture of the UK landscape in decline is described as "worrying" by researchers. Toads "don't need very particular environments" and "ought to live quite well in the majority of areas in the UK," meaning if even they are struggling to persist, "it indicates that the ecosystem is unbalanced."

The Threat from Traffic

Though the study didn't examine the causes for the decline, cars is a major factor. Calculations suggest that 20 tons of toads are killed on UK roads annually – in other words, hundreds of thousands. Unlike frogs, which would probably be content to mate "if you left out a small container," toads prefer big bodies of water. Their ability to remain away from water for more time than frogs means they can journey farther to reach them – sometimes long distances. They tend to stick to their ancestral migration routes – it's common for adult toads to go back to their natal pond to mate.

Breeding Patterns

Fittingly, the first toads begin their quest for a mate around February 14th, but some move as far as spring, waiting until it gets night and travelling through the night. During that period, toads start moving from where they have been overwintering "almost simultaneously."

One volunteer, who grew up in the area and has been working to save its amphibians since he was a child, explains that "They've got just one focus: to go and have an orgy." If their path crosses 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

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

Patrols usually work during the migration season, when toad crossings are more regular. However, this implies they can miss numbers of young toads, which, having existed as eggs and then juveniles, exit 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 vehicles." And as being hit "essentially crushes them," it's harder to get data on them. At least when adult toads are killed, their carcasses can be tallied.

Year-Round Efforts

Unlike many groups, one local team, who are in their eighth year of operating, go out year-round – not nightly, 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 duty, they concede it is "not ideal conditions" – winter dormancy has started 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 find any toads tonight, those two will find one," says the patrol manager, indicating her teenage child and the longtime volunteer. We've been out for 120 minutes without a single toad sighting, and now they have climbed over a barbed wire fence to check under some wood.

Community Participation

The mother and son became part of the patrol 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 jointly to protect native animals. Now she loves it as much as he does, the 41-year-old small business owner tells me – so when the group was seeking a new manager recently, she volunteered for the role.

The youth, too, has played an important role in the organization. A video he created, urging the local council to close a street through a nature reserve during breeding time, influenced the outcome the team's way. After a year of lobbying, the council agreed to an "restricted access" restriction between evening and morning from February through to April. The majority of motorists duly avoided the road.

Other Wildlife and Challenges

Several cars go by when I'm out on patrol and we find some casualties as a result – no toads, but three squashed newts. We see one living newt as well, and the teenager is particularly pleased to see a harvestman, which moves in his hands. Yet despite the team's hardest attempts to show me a toad, the local population has obviously settled down for the colder months. It appears that I couldn't have found any better success elsewhere in the nation – all the rescue teams I contact explain that it's near-impossible at this time of year.

The group expects to help approximately 10,000 adult toads across the road

A message I receive from a different helper, who has generously made the effort to look for toads in a noted location, considered the biggest tracked toad group in the UK, arrives in my inbox with the title: "None found." However, in February and March, he informs me, the group plans to assist around ten thousand mature amphibians over the street.

Impact and Challenges

How much of a difference can these groups truly achieve? "The fact that volunteers are performing this consistently on chilly, wet and miserable evenings is quite extraordinary," says an expert. "This effort that very much deserves recognition." However, while toad patrols are able to reduce the drop, they can't stop it completely – partly since vehicles is just one danger.

Other Dangers

The climate crisis has resulted in extended spells of drought, which create the wrong conditions for some of the animals that toads eat, such as invertebrates, while higher water temperatures have caused an increase of toxic plants, which can be toxic to toads. Milder winters also lead toads to emerge from their hibernation more often, interfering with the energy conservation crucial to their existence. Habitat destruction – particularly the disappearance of large ponds – is an additional threat.

Experts are "always a bit worried about putting too much of a utilitarian spin on wildlife," however "It's important in just their presence." But toads play an significant part in the food chain, consuming almost any invertebrates or tiny organisms they can fit in their mouths and in turn sustaining a number of birds and mammals, such as hedgehogs and otters. Enhancing conditions for toads – such as creating more ponds, conserving woodland and installing toad tunnels – "benefits for a wide range of other species."

Historical Importance

Another reason to work to preserve toads around is their "historical significance," notes an specialist. Myths and folklore around toads go back {centuries|hundred
