Can the UK's Toads Be Saved from Traffic and Terrible Decline?
It's a Friday evening at 7:30, but rather than heading to the pub or relaxing at home, I've caught a train to a town in the countryside to meet up with volunteers from a toad patrol. These committed people sacrifice their nights to safeguard the native amphibian community.
A Worrying Drop in Population
The Bufo bufo is growing more uncommon. A latest study conducted by an wildlife conservation group showed 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 decrease is labeled "concerning" by researchers. Toads "don't need very particular environments" and "should be able to live successfully in the majority 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 Danger from Roads
Though the research didn't examine the causes for the drop, traffic certainly plays a part. Estimates indicate that 20 tonnes of toads are crushed on British roads annually – that is, hundreds of thousands. Unlike frogs, which might be content to mate "with just a small container," toads prefer large ponds. Their ability to stay out of water for longer than frogs allows they can journey farther to find them – sometimes hundreds of metres. They usually stick to their ancestral migration routes – it's typical for mature amphibians to return to their natal pond to mate.
Breeding Patterns
Fittingly, the first toads start their journey for a partner around February 14th, but some move as far as spring, waiting until it gets dark and travelling through the night. During that period, toads begin migrating from where they have been overwintering "all pretty much at the same time."
A local helper, who was raised in the area and has been trying to protect its amphibians since he was a boy, notes that "Their sole purpose: to go and have an orgy." If their route crosses a street, they could all get run over, and that breeding season would never happen – stopping a next generation of toads from being born.
Rescue Groups Throughout the United Kingdom
Finding hundreds of toad carcasses on local roads "resonates deeply with people," and has resulted in the creation of toad patrols across the UK – hundreds of organizations are officially listed with a national initiative. These groups collect toads and carry them over streets in buckets, as well as recording the quantity of toads they encounter and lobbying for other protection measures, such as blocked roads and amphibian passages.
Volunteers tend to operate during the migration season, when toad crossings are frequent. However, this implies they can overlook numbers of toadlets, which, having existed as eggs and then juveniles, exit their water habitats over an irregular timetable in the end of summer. Because of their size – just a couple of cm wide – "they can get obliterated by vehicles." And as being run over "essentially crushes them," it's harder to get data on them. At least when mature amphibians are lost, their carcasses can be tallied.
Year-Round Efforts
Unlike most patrols, a specific volunteer group, who are in their eighth year of operating, go out year-round – not every night, but when conditions are damp, or if a member has posted about a toad sighting in their group chat. When I request to accompany them on patrol, they admit it is "not ideal conditions" – winter dormancy has started and it's been a arid period – but several of the helpers willingly accept to patrol their route with me and see what we can find. "Should anyone can locate any toads tonight, that pair will find one," says the patrol manager, pointing to her 14-year-old son and the longtime volunteer. We've been out for two hours without a single toad sighting, and now they have scaled a barbed wire fence to check under some wood.
Family Participation
The mother and son joined the patrol a while back. The teenager adores all things nature-related and has an goal to become a environmentalist, so his mother started to search for things they could do together to help local wildlife. Now she loves it as much as he does, the middle-aged small business owner explains – so when the team was seeking a new manager recently, she decided to step up.
The teenager, too, has played an important role in the group. A clip he made, urging the municipal authority to close a street through a nature reserve during migration season, swung the decision the team's way. After a twelve months of lobbying, 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.
Additional Species and Challenges
Several cars go by when I'm out on patrol and we discover some victims as a result – no toads, but three squashed newts. We spot one live amphibian as well, and the teenager is particularly pleased to see a daddy longlegs, which moves in his hands. Yet despite the group's best efforts to let me see a toad, the native community has obviously settled down for the colder months. It seems that I couldn't have found any better success elsewhere in the country – all the rescue teams I reach out to explain that it's near-impossible at this season.
The group expects to help approximately 10,000 adult toads across the road
A message I get from another volunteer, who has generously taken the trouble to check for toads in a famous site, considered the biggest tracked toad group in the UK, reaches me with the title: "No toads." However, in February and March, he informs me, the group expects to help approximately ten thousand mature amphibians over the street.
Impact and Challenges
What level of impact can these groups actually make? "The fact that people are performing this consistently on cold, damp and unpleasant late nights is quite extraordinary," notes an expert. "That's something that very much should be celebrated." However, while rescue teams are able to slow the decline, they cannot prevent it entirely – partly since traffic is not the only threat.
Additional Threats
The climate crisis has resulted in longer periods of dry weather, which cause the wrong conditions for some of the animals that toads eat, such as worms and slugs, while higher water temperatures have led to an increase of toxic plants, which can be harmful to toads. Milder winters also lead toads to emerge from their dormancy more frequently, disrupting the energy conservation crucial to their existence. Loss of environment – especially the loss of big water bodies – is another menace.
Researchers are "always a bit worried about putting too much of a utilitarian spin on wildlife," but "There is a big value in just their presence." But toads do have an important role in the food chain, eating almost any small creatures or small animals they can swallow and in turn feeding a number of predators, such as wildlife. Improving conditions for toads – ie building water habitats, protecting forests and installing amphibian passages – "benefits for a wide range of other species."
Historical Importance
Another reason to work to preserve toads present is their "important cultural value," notes an expert. Myths and folklore around toads go back {centuries|hundred
