Will the UK's Toads Be Saved from Roads and Population Collapse?

It's Friday night at half past seven, but rather than heading to the pub or watching a film, I've taken a train to a town in Wiltshire to meet up with local helpers from a amphibian rescue group. These committed people give up their nights to safeguard the local toad population.

A Worrying Decline in Numbers

The Bufo bufo is growing more rare. A recent research conducted by an amphibian and reptile charity showed that the UK toad population have dropped by half since the mid-1980s. Observing a species that has been a fixture of the UK landscape in decline is described as "concerning" by researchers. Toads "don't need very specific conditions" and "ought to live successfully in the majority of areas in Britain," so if even they are not managing to survive, "it indicates that things are not as they should be."

The Threat from Traffic

Though the research didn't examine the reasons for the decline, traffic certainly plays a part. Calculations indicate that 20 tonnes of toads are killed on UK roads every year – that is, several hundred thousand. Unlike frogs, which might be content to mate "with just a bucket of water," toads prefer large ponds. Their ability to remain away from water for more time than frogs means they can journey farther to find them – sometimes long distances. They tend to stick to their traditional paths – it's typical for adult toads to return to their natal pond to mate.

Migration Habits

Appropriately enough, the first toads begin their quest for a mate around February 14th, but some move as late as April, until it gets night and travelling after sunset. During that period, toads begin migrating from wherever they have been overwintering "almost simultaneously."

One volunteer, who was raised in the region and has been working to save its amphibians since he was a boy, explains that "Their sole purpose: to go and have an orgy." If their path crosses a road, they could all get run over, and that breeding season would be lost – stopping a new generation of toads from being produced.

Rescue Groups Throughout the United Kingdom

Finding many of dead toads on nearby streets "inherently strikes a chord with people," and has led to the creation of toad patrols throughout the UK – 274 groups are officially listed with a countrywide program. These groups pick up toads and transport them across roads in buckets, as well as counting the quantity of toads they find and lobbying for other safety solutions, such as road closures and amphibian passages.

Patrols tend to operate during the breeding period, when amphibian movements are more regular. However, this implies they can miss groups of young toads, which, having been eggs and then tadpoles, leave their water habitats over an unpredictable schedule in the end of summer. Because of their small stature – just a couple of cm wide – "they are destroyed by vehicles." And as being run over "basically turns them into mush," it's harder to collect information on them. At least when adult toads are killed, their carcasses can be counted.

Annual Efforts

In contrast to many groups, one local team, who are in their eighth year of functioning, go out throughout the year – not nightly, but whenever conditions are warm and wet, or if someone has posted about a amphibian spotting 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 dry day – but several of the helpers gamely agree to patrol their area with me and search for any toads. "If anyone can locate any toads tonight, those two will find one," says the group coordinator, indicating her teenage child and the longtime volunteer. After for two hours without a glimpse of any amphibians, and now they have scaled a wire barrier to check under some wood.

Family Participation

The mother and son became part of the patrol a while back. The youngster adores all things nature-related and has an goal to become a environmentalist, so his parent started to look for things they could do together to help local wildlife. Now she loves it as much as he does, the 41-year-old entrepreneur tells me – so when the group was looking for a fresh coordinator recently, she decided to step up.

The youth, too, has been instrumental in the organization. A clip he created, imploring the municipal authority to block a street through a nature reserve during breeding time, influenced the outcome the group's way. After a twelve months of campaigning, the authority agreed to an "access-only" rule between evening and morning from February through to spring. Most drivers duly avoided the route.

Additional Species and Challenges

A few cars go past when I'm out on duty and we discover some victims 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 hands. Yet despite the team's hardest attempts to show me a toad, the local population has obviously gone dormant for the colder months. It appears that I couldn't have found any more luck anywhere else in the nation – all the patrol groups I reach out to clarify that it's very difficult at this season.

They project rescuing nearly 10,000 grown amphibians during migration

One email I receive from a different helper, who has generously taken the trouble to check for toads in a famous site, considered the biggest tracked toad population in the UK, arrives in my inbox with the title: "No toads." However, in February and March, he informs me, the group expects to help around 10,000 adult toads over the street.

Impact and Limitations

What level of impact can these groups actually make? "The fact that people are performing this regularly on cold, damp and unpleasant late nights is remarkable," says an researcher. "This effort that very much deserves recognition." However, while rescue teams are able to slow the decline, they cannot prevent it entirely – 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 worms and slugs, 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 dormancy more often, disrupting the resource preservation crucial to their existence. Loss of environment – especially the loss of large ponds – is an additional threat.

Experts are "always a bit worried about overemphasizing practical benefits on wildlife," but "There is a big value in just their presence." But toads do have an significant part in the food chain, consuming pretty much any invertebrates or tiny organisms they can swallow and in turn feeding a variety of predators, such as wildlife. Enhancing situations for toads – ie building water habitats, conserving woodland and constructing toad tunnels – "we'll improve them for a wide range of other species."

Cultural Significance

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