It is a Friday night at 7:30, but rather than heading to the pub or watching a film, I've taken a train to a market town in Wiltshire to meet up with volunteers from a amphibian rescue group. These committed people give up their nights to protect the native amphibian community.

An Alarming Drop in Population

The common toad is growing more rare. A latest study led by an wildlife conservation group revealed that the UK toad population have almost halved since 1985. Observing a creature that has been a stalwart of the UK landscape in decline is labeled "worrying" by researchers. Toads "don't require very specific conditions" and "ought to live successfully in most of habitats in Britain," meaning if even they are not managing to survive, "it indicates that the ecosystem is unbalanced."

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

The Threat from Traffic

Though the research didn't examine the causes for the decline, traffic is a major factor. Estimates suggest that 20 tonnes of toads are crushed on British roads every year – in other words, several hundred thousand. Unlike frogs, which would probably be happy to mate "if you left out a bucket of water," toads favor large ponds. Their ability to stay out of water for more time than frogs means they can travel further to reach them – sometimes hundreds of metres. They tend to follow their traditional paths – it's typical for adult toads to go back to their natal pond to mate.

Breeding Patterns

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

A local helper, who grew up in the region and has been working to save its amphibians since he was a child, notes that "Their sole purpose: to go and have an orgy." If their route crosses a street, they could be killed by traffic, and that breeding season would never happen – preventing a new generation of toads from being produced.

Toad Patrols Across the UK

Seeing many of toad carcasses on local roads "resonates deeply with people," and has led to the formation of toad patrols throughout the UK – 274 groups are officially listed with a national initiative. These teams collect toads and carry them across roads in containers, as well as recording the quantity of toads they encounter and advocating for other safety solutions, such as blocked roads and amphibian passages.

Volunteers usually work during the migration season, when amphibian movements are more regular. However, this implies they can overlook numbers of toadlets, which, having existed as spawn and then tadpoles, leave their water habitats over an unpredictable schedule 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 "basically turns them into mush," it's more difficult to get data on them. At least when mature amphibians are killed, their carcasses can be counted.

Annual Efforts

Unlike many groups, a specific volunteer group, who are in their eighth season of functioning, go out throughout the year – not nightly, but whenever weather are warm and wet, 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 a toady night" – toad hibernation season 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. "If anyone can find any toads tonight, that pair will find one," says the group coordinator, indicating her teenage child and the longtime volunteer. After for two hours without a single toad sighting, and now they have scaled a wire barrier to inspect beneath some logs.

Family Involvement

The family duo joined the patrol a year and a half ago. The teenager adores all things wildlife and has an ambition to become a environmentalist, so his parent started to search for activities they could do together to help local wildlife. Now she loves it as much as he does, the 41-year-old entrepreneur explains – so when the team was seeking a fresh coordinator recently, she decided to step up.

The youth, too, has played an important role in the organization. A video he made, urging the municipal authority to close a street through a protected area during migration season, influenced the outcome the group's way. After a twelve months of campaigning, the council agreed to an "restricted access" rule between evening and morning from late winter through to April. Most drivers respected and avoided the road.

Other Wildlife and Challenges

A few vehicles go past when I'm out on duty and we find some casualties as a result – no toads, but several crushed salamanders. We spot one living newt as well, and the youngster is particularly pleased to see a daddy longlegs, which moves in his hands. Yet despite the team's best efforts to let me see a toad, the local population has clearly gone dormant 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 explain that it's very difficult at this season.

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

One email I get from another volunteer, who has generously taken the trouble to check for toads in a noted location, thought to be 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 approximately ten thousand adult toads across the road.

Effectiveness and Challenges

How much of a difference can these organizations actually make? "The fact that volunteers are doing this regularly on cold, damp and unpleasant late nights is quite extraordinary," notes an expert. "That's something that very much should be celebrated." However, while toad patrols are able to slow the decline, they cannot prevent it entirely – 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 animals that toads consume, such as invertebrates, while warmer ponds have led to an increase of blue-green algae, which can be harmful to toads. Milder winters also lead toads to wake up from their dormancy more often, disrupting the energy conservation vital to their life cycle. Habitat destruction – especially the loss of large ponds – is an additional threat.

Researchers are "often concerned about overemphasizing practical benefits on biodiversity," however "It's important in just having these animals around." But toads do have an important role in the food chain, eating pretty much any invertebrates or tiny organisms they can fit in their mouths and in turn feeding a variety of predators, such as wildlife. Enhancing situations for toads – ie creating more ponds, protecting forests and constructing amphibian passages – "benefits for a wide range of other species."

Historical Significance

Another reason to work to preserve toads present is their "historical significance," notes an specialist. Myths and folklore around toads go back {centuries|hundred
