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

A Worrying Decline in Population

The common toad is becoming increasingly uncommon. A recent study led by an amphibian and reptile charity showed that the British common toad numbers have dropped by half since the mid-1980s. Observing a species that has been a stalwart of the UK landscape in decrease is described as "concerning" by experts. Toads "don't require very particular environments" and "should be able to live successfully in most of areas in Britain," meaning if even they are not managing to survive, "it kind of suggests that the ecosystem is unbalanced."

Toad populations across the UK have declined by almost 50% since the 1980s

The Danger from Traffic

Though the study didn't cover the causes for the decline, cars is a major factor. Calculations indicate that 20 tons of toads are killed on British roads annually – in other words, several hundred thousand. In contrast to frogs, which would probably be happy to mate "with just a bucket of water," toads prefer large ponds. Their capacity to stay out of water for longer than frogs means 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 birth pond to mate.

Migration Habits

Appropriately enough, the initial amphibians begin their quest for a partner around Valentine's day, but some move as far as spring, until it gets night and moving after sunset. During that period, toads start moving from wherever they have been hibernating "all pretty much at the same time."

A local helper, who grew up in the area and has been working to save its amphibians since he was a boy, notes that "They've got just one focus: to go and mate." If their route crosses a road, they could be killed by traffic, and that mating period would be lost – stopping a next generation of toads from being born.

Rescue Groups Throughout the United Kingdom

Finding hundreds of dead toads on local roads "resonates deeply with people," and has resulted in the formation of rescue teams across the UK – hundreds of organizations are officially listed with a national initiative. These teams pick up toads and carry them across roads in buckets, as well as counting the number of toads they find and advocating for other safety solutions, such as blocked roads and amphibian passages.

Volunteers usually work during the migration season, when toad crossings are frequent. However, this means they can overlook groups of young toads, which, having existed as eggs and then tadpoles, 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 hit "basically turns them into mush," it's more difficult to get data on them. At least when mature amphibians are lost, their carcasses can be tallied.

Annual Work

In contrast to many groups, one local team, who are in their eighth year of functioning, go out year-round – not nightly, but whenever conditions are warm and wet, or if a member has reported about a toad sighting in their group chat. When I ask to join them on patrol, they concede it is "not ideal conditions" – winter dormancy has begun and it's been a arid period – but several of the helpers willingly accept to walk up and down their area with me and see what we can find. "Should anyone can find 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 120 minutes without a single toad sighting, and now they have climbed over a wire barrier to inspect beneath some logs.

Community Involvement

The family duo joined the patrol a year and a half ago. The teenager loves all things wildlife and has an ambition to become a conservationist, 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 41-year-old entrepreneur tells me – so when the group was seeking a new manager recently, she decided to step up.

The youth, too, has played an important role in the group. A video he created, imploring the local council to block a road through a nature reserve during breeding time, influenced the outcome the team's way. After a year of lobbying, the authority agreed to an "access-only" restriction between 5pm and 5am from February through to spring. The majority of motorists duly avoided the route.

Additional Species and Difficulties

Several cars go by when I'm out on patrol and we discover some victims as a consequence – no amphibians, but several crushed salamanders. We see one live amphibian as well, and the teenager is particularly pleased to see a daddy longlegs, which moves in his palms. Yet in spite of the team's best efforts 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 elsewhere in the nation – all the patrol groups I contact clarify that it's very difficult at this time of year.

One email I receive from another volunteer, who has generously taken the trouble to look for toads in a famous site, thought to be the biggest tracked toad group in the UK, reaches me with the title: "None found." However, in February and March, he informs me, the team expects to help approximately ten thousand adult toads over the street.

Impact and Limitations

How much of a difference can these groups truly achieve? "The reality that people are doing this regularly on cold, damp and unpleasant late nights is quite extraordinary," notes an researcher. "This effort that very much deserves recognition." However, while toad patrols are able to slow the decline, they can't stop it completely – partly since vehicles is not the only threat.

Other Dangers

The climate crisis has meant extended spells of drought, which cause the wrong conditions for some of the creatures that toads consume, such as worms and slugs, while warmer ponds have led to an rise of toxic plants, which can be harmful to toads. Milder winters also cause toads to emerge from their hibernation more frequently, disrupting the energy conservation crucial to their existence. Habitat destruction – particularly the loss of big water bodies – is an additional threat.

Researchers 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 pretty much any invertebrates or tiny organisms they can fit in their mouths and in turn feeding a variety of birds and mammals, such as wildlife. Improving situations for toads – such as creating more ponds, protecting forests and constructing toad tunnels – "we'll improve them for a wide range of additional wildlife."

Historical Importance

An additional motive to work to preserve toads present is their "important cultural value," notes an specialist. Myths and folklore around toads date back {centuries|hundred
