It's a Friday evening at half past seven, but instead of going out or watching a film, I've taken a train to a town in Wiltshire to meet up with volunteers from a amphibian rescue group. These dedicated individuals give up their nights to safeguard the local toad population.

A Worrying Drop in Numbers

The Bufo bufo is growing more uncommon. A recent research conducted by an amphibian and reptile charity showed that the UK toad population have almost halved since 1985. Seeing a species that has been a stalwart of the British countryside in decrease is labeled "concerning" by experts. Toads "don't need very particular environments" and "should be able to live quite well in the majority of habitats in the UK," so if even they are struggling to persist, "it kind of suggests that things are not as they should be."

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

The Threat from Traffic

Though the study didn't examine the causes for the decline, traffic certainly plays a part. Calculations indicate that 20 tonnes of toads are crushed on British roads annually – in other words, hundreds of thousands. In contrast to frogs, which might be content to mate "if you left out a small container," toads prefer big bodies of water. Their capacity to remain away from water for more time than frogs means they can journey farther to find them – often hundreds of metres. They usually stick to their traditional paths – it's common for adult toads to return to their birth pond to mate.

Migration Habits

Fittingly, the initial amphibians start their journey for a partner around February 14th, but some move as far as April, until it gets night and moving through the night. During that time, toads begin migrating from where they have been hibernating "all pretty much at the same time."

A local helper, who was raised in the region and has been working to save its toad population since he was a boy, explains that "They've got just one focus: to go and mate." If their route crosses a road, they could all get run over, and that mating period would never happen – stopping a next generation of toads from being produced.

Toad Patrols Throughout the UK

Seeing many of dead toads on local roads "resonates deeply with people," and has led to the creation of toad patrols throughout the UK – hundreds of organizations are officially listed with a countrywide program. These groups collect toads and carry them over streets in buckets, as well as recording the number of toads they find and lobbying for other safety solutions, such as road closures and amphibian passages.

Patrols usually work during the breeding period, when toad crossings are frequent. However, this implies they can miss numbers of toadlets, which, having been eggs and then tadpoles, exit their ponds over an irregular timetable in late summer. Because of their small stature – just one or two centimetres 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 adult toads are killed, their carcasses can be counted.

Year-Round Efforts

In contrast to many groups, a specific volunteer group, who are in their eighth season of functioning, go out throughout the year – not every night, but whenever conditions are damp, or if someone has posted about a amphibian spotting in their group chat. When I request to accompany them on duty, they admit it is "not a toady night" – toad hibernation season has begun and it's been a arid period – but several of the volunteers gamely agree to walk up and down their route with me and see what we can find. "If anyone can locate any toads tonight, that pair will find one," says the group coordinator, 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 check under some logs.

Family Involvement

The family duo joined the group a year and a half ago. The youngster loves all things nature-related and has an goal to become a conservationist, so his mother started to search for things they could do together to protect native animals. Now she enjoys it as much as he does, the 41-year-old small business owner tells me – so when the team was seeking a fresh coordinator recently, she decided to step up.

The youth, too, has been instrumental in the organization. A clip he made, imploring the municipal authority to block a street through a nature reserve during migration season, swung the decision the group's way. After a year of campaigning, the authority approved an "access-only" rule between evening and morning from late winter through to April. The majority of motorists respected and avoided the route.

Additional Species and Challenges

Several cars go by when I'm out on patrol and we find some victims as a result – no amphibians, but several crushed salamanders. We spot one living newt as well, and the teenager is particularly pleased to see a daddy longlegs, which moves in his palms. Yet in spite of the group's hardest attempts to show me a toad, the native community has obviously settled down for the winter. It appears that I couldn't have found any more luck elsewhere in the country – all the patrol groups I contact clarify that it's near-impossible at this time of year.

One email I get from a different helper, who has kindly taken the trouble to check for toads in a noted location, thought to be the largest accurately monitored toad population in the UK, arrives in my inbox with the title: "None found." However, in February and March, he informs me, the group plans to assist approximately ten thousand mature amphibians over the street.

Effectiveness and Limitations

How much of a difference can these groups actually make? "The fact that volunteers are doing this consistently on cold, damp and unpleasant evenings is remarkable," notes an researcher. "That's something that very much deserves recognition." However, while toad patrols are able to slow the decline, they cannot prevent it entirely – partly since traffic is not the only threat.

Additional Threats

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 worms and slugs, while warmer ponds have led to an rise of blue-green algae, which can be toxic to toads. Warmer cold seasons also cause toads to emerge from their hibernation more often, disrupting the energy conservation crucial to their life cycle. Loss of environment – particularly the disappearance of big water bodies – is another menace.

Experts are "often concerned about overemphasizing practical benefits on wildlife," but "It's important in just having these animals around." But toads do have an important role in the ecosystem, consuming almost any invertebrates or small animals they can fit in their mouths and in turn sustaining a variety of birds and mammals, such as hedgehogs and otters. Enhancing conditions for toads – such as creating more ponds, conserving woodland and constructing toad tunnels – "we'll improve them for a whole bunch of other species."

Historical Importance

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