It's a Friday night at half past seven, but instead of heading to the pub or watching a film, I've taken a train to a market town in the countryside to meet up with volunteers from a amphibian rescue group. These dedicated individuals sacrifice their evenings to safeguard the native amphibian community.

A Worrying Decline in Population

The Bufo bufo is growing more rare. A recent study led by an wildlife conservation group revealed that the UK toad population have almost halved since the mid-1980s. Seeing a creature that has been a stalwart of the British countryside in decline is described as "worrying" by researchers. Toads "don't require very particular environments" and "ought to live successfully in most of areas in the UK," meaning if even they are not managing to survive, "it kind of suggests that the ecosystem is unbalanced."

Since 1985, Britain's toad numbers have nearly been cut in half

The Danger from Roads

Though the research didn't examine the causes for the decline, traffic is a major factor. Estimates suggest that 20 tons of toads are killed on UK roads every year – in other words, several hundred thousand. Unlike frogs, which might be happy to mate "if you left out a small container," toads favor large ponds. Their capacity to stay out of water for more time than frogs means they can journey farther to reach them – sometimes long distances. They usually stick to their traditional paths – it's typical for adult toads to return to their natal pond to mate.

Breeding Habits

Appropriately enough, the initial amphibians start their journey for a mate around February 14th, but some move as late as spring, waiting until it gets night and travelling through the night. During that time, toads start moving from wherever they have been hibernating "almost simultaneously."

A local helper, who grew up in the region and has been trying to protect its toad population since he was a child, explains that "They've got just one focus: to go and have an orgy." If their path crosses a street, they could be killed by traffic, and that breeding season would be lost – stopping a next generation of toads from being produced.

Toad Patrols Across the United Kingdom

Seeing many of toad carcasses on local roads "resonates deeply with people," and has led to the creation of toad patrols across the UK – 274 groups are officially listed with a countrywide program. These groups collect toads and carry them over streets in containers, as well as recording the number of toads they find and lobbying for other safety solutions, such as road closures and underground wildlife tunnels.

Patrols usually work during the migration season, when amphibian movements are more regular. However, this implies they can overlook groups of toadlets, which, having existed as spawn and then juveniles, exit their water habitats over an unpredictable schedule in late summer. Because of their small stature – just one or two centimetres wide – "they are destroyed by vehicles." And as being run over "basically turns them into mush," it's more difficult to collect information on them. At least when mature amphibians are lost, their carcasses can be counted.

Annual Efforts

Unlike most patrols, a specific volunteer group, who are in their eighth year of functioning, go out throughout the year – not every night, but whenever conditions 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 admit it is "not ideal conditions" – toad hibernation season has begun and it's been a arid period – but a few of the helpers gamely agree to patrol their area with me and see what we can find. "Should anyone can locate any toads tonight, that pair will spot one," says the patrol manager, indicating her teenage child and the experienced member. We've been out for two hours without a glimpse of any amphibians, and now they have scaled a barbed wire fence to inspect beneath some wood.

Community Participation

The mother and son became part of the group a year and a half ago. The teenager loves all things nature-related and has an ambition to become a conservationist, so his parent started to look for things they could do jointly to help 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 lately, she decided to step up.

The teenager, too, has been instrumental in the group. A clip he created, urging the local council to close a street through a protected area during migration season, influenced the outcome the team's way. After a year of lobbying, the authority approved an "restricted access" rule between evening and morning from February through to April. Most drivers duly avoided the road.

Other Wildlife and Difficulties

A few vehicles go past when I'm out on duty and we find some victims as a result – no toads, but several crushed salamanders. We see one live amphibian as well, and the teenager is particularly pleased to see a harvestman, which dances in his hands. Yet in spite of the team's hardest attempts to show me a toad, the native community has obviously gone dormant for the colder months. It seems that I wouldn't have had any more luck elsewhere in the country – all the rescue teams I contact explain that it's very difficult at this time of year.

This team anticipates assisting around ten thousand mature toads over the street

One email I get from another volunteer, who has kindly taken the trouble to look for toads in a famous site, considered the largest accurately monitored toad population in the UK, reaches me with the subject line: "None found." However, in late winter, he informs me, the team plans to assist approximately ten thousand adult toads over the street.

Impact and Limitations

What level of impact can these groups actually make? "The fact that volunteers are performing this regularly on cold, damp and unpleasant evenings is remarkable," notes an expert. "That's something that very much deserves recognition." However, while rescue teams are able to slow the decline, they can't stop it completely – partly since vehicles is just one danger.

Additional Threats

The climate crisis has resulted in extended spells of drought, which cause the poor environment 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 harmful to toads. Milder winters also cause toads to emerge from their dormancy more frequently, disrupting the resource preservation 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 biodiversity," however "There is a big value in just their presence." But toads play an significant part in the food chain, consuming almost any small creatures or small animals they can swallow and in turn feeding a variety of predators, such as wildlife. Enhancing situations for toads – such as creating more ponds, protecting forests and constructing amphibian passages – "we'll improve them for a whole bunch of additional wildlife."

Historical Significance

Another reason to try to keep toads present is their "important cultural value," notes an expert. Legends and tales around toads go back {centuries|hundred
