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

It's 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 Wiltshire to join local helpers from a amphibian rescue group. These committed people give up their nights to protect the native amphibian community.

A Worrying Drop in Numbers

The Bufo bufo is becoming increasingly rare. A recent research conducted by an wildlife conservation group showed that the UK toad population have dropped by half since 1985. Observing a creature that has been a stalwart of the UK landscape in decrease is labeled "concerning" by experts. Toads "don't need very specific conditions" and "ought to live quite well in most of habitats in the UK," so if even they are struggling to persist, "it indicates that the ecosystem is unbalanced."

The Threat from Roads

Though the research didn't cover the reasons for the decline, traffic is a major factor. Calculations indicate that 20 tonnes of toads are killed on British roads annually – in other words, hundreds of thousands. In contrast to frogs, which might be happy to mate "with just a small container," toads favor big bodies of water. Their capacity to remain away from water for more time than frogs allows they can travel further to reach them – often hundreds of metres. They usually stick to their ancestral migration routes – it's common for adult toads to return to their natal pond to mate.

Migration Patterns

Fittingly, the first toads start their journey for a partner around February 14th, but some move as far as April, waiting until it gets night and moving after sunset. During that time, toads begin migrating from wherever they have been hibernating "almost simultaneously."

A local helper, who grew up in the region and has been working to save its amphibians since he was a child, notes that "They've got just one focus: to go and have an orgy." If their path crosses a street, they could all get run over, and that breeding season would never happen – stopping a new generation of toads from being born.

Toad Patrols Throughout the UK

Seeing hundreds of dead toads on local roads "resonates deeply with people," and has led to the creation of toad patrols throughout the UK – 274 groups are currently registered with a national initiative. These groups collect toads and carry them over streets in buckets, as well as counting the number of toads they find and lobbying for other safety solutions, such as blocked roads and amphibian passages.

Volunteers tend to operate during the breeding period, when amphibian movements are more regular. However, this means they can overlook groups of toadlets, which, having existed as spawn and then juveniles, leave their water habitats over an irregular timetable in the end of summer. Because of their small stature – just a couple of cm wide – "they are destroyed by vehicles." And as being hit "basically turns them into mush," it's harder to collect information on them. At least when mature amphibians are lost, their remains can be counted.

Year-Round Efforts

Unlike many groups, one local team, who are in their eighth year of operating, go out throughout the year – not nightly, but whenever weather are damp, or if someone has reported about a toad sighting in their messaging app. When I ask to join 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 area with me and see what we can find. "Should anyone can locate any toads tonight, that pair will find one," says the patrol manager, indicating her 14-year-old son and the longtime volunteer. We've been out for 120 minutes without a single toad sighting, and now they have climbed over a wire barrier to check under some wood.

Community Involvement

The family duo joined the patrol a while back. The youngster adores all things nature-related and has an ambition to become a environmentalist, so his mother started to look for things they could do jointly to protect 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 lately, she decided to step up.

The youth, too, has played an important role in the organization. A clip he created, imploring the municipal authority to close a street through a nature reserve during migration season, influenced the outcome the group's way. After a twelve months of campaigning, the council approved an "restricted access" rule between 5pm and 5am from late winter through to spring. Most drivers duly avoided the route.

Additional Species and Difficulties

A few vehicles go past when I'm out on duty and we find some casualties as a result – no amphibians, but several crushed salamanders. We see one living newt as well, and the teenager is especially excited to see a harvestman, which moves in his palms. Yet despite the group's hardest attempts to show me a toad, the local population has clearly settled down for the winter. It seems that I couldn't have found any more luck anywhere else in the country – all the rescue teams I contact clarify that it's very difficult at this time of year.

A message I receive from a different helper, who has generously taken the trouble to look for toads in a noted location, considered the biggest tracked toad population in the UK, arrives in my inbox with the title: "None found." However, in late winter, he informs me, the team plans to assist around 10,000 adult toads across the road.

Effectiveness and Challenges

What level of impact can these groups actually make? "The fact that people are doing this regularly on chilly, wet and miserable late nights is remarkable," notes an researcher. "That's something that very much should be celebrated." However, while toad patrols are able to reduce the drop, they can't stop it completely – partly since traffic is not the only threat.

Other Dangers

The global warming has meant extended spells of dry weather, which create the poor environment for some of the creatures that toads eat, such as worms and slugs, while warmer ponds have caused an increase of toxic plants, which can be harmful to toads. Warmer cold seasons also lead toads to emerge from their dormancy more often, interfering with the energy conservation crucial to their life cycle. Habitat destruction – especially the loss of big water bodies – is another menace.

Researchers are "always a bit worried about overemphasizing practical benefits on biodiversity," but "It's important in just having these animals around." But toads do have an important role in the food chain, eating almost any small creatures or tiny organisms they can fit in their mouths and in turn feeding a number of predators, such as hedgehogs and otters. Enhancing conditions for toads – ie building water habitats, conserving woodland and installing amphibian passages – "benefits for a wide range of other species."

Historical Significance

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